Definitions
- the handpiece includes transducer means for converting a high frequency alternating current into mechanical vibrations and an impedance transformer for coupling these vibrations to the operative tips. Connections are also provided on the handpiece to a source of treatment fluid and a pump.
- the treatment fluid may be coupled to either the hollow interior of the tool or the surrounding annular passage, while the pump is coupled to the other.
- the vibration of the operative tip against the tissue to be removed causes the latter to break apart into small particles which are then dispersed in the fluid flowing over the operative region.
- the pump withdraws the suspension of the tissue particles in the fluid from the operative site.
- the fluid flow must be regulated so as to control the pressure within limits at the operative site.
- the instrument is thus suitable for removing tissue from an enclosed area whereby the opening to permit access to the tissue to be removed need only be large enough to admit the tip of the operative tool.
- the present invention relates to material removal devices and methods, and more particularly to an instrument having a working operative tip vibrating at high frequencies and with minute amplitudes for breaking apart and removing material from relatively inaccessible places and techniques for its use.
- the present apparatus is of particular advantage when employed as a surgical instrument for breaking apart and the removal of unwanted tissue.
- Vibratory assemblies for the cutting of material have been in use for some time in a wide number of applications.
- One form of such apparatus employs a slurry formed of particles of abrasive material in a liquid medium in conjunction with an ultrasonically vibrating tool, whereby the vibratory energy imparted to the abrasive particles in the slurry hurl them against the surface to be cut with tremendous accelerations, thereby literally chipping away the material.
- This technique has been applied with great success to a wide variety of uses, particularly with respect to industrial machine tools.
- the instrument described herein thus lends itself to the performance of delicate surgical procedures in extremely limited areas.
- One such surgical procedure, for which the instrument has proven especially effective, is the removal of cataracts from the eye.
- a cataract Operation requires total removal of the clouded lens which is usually accomplished by a 180 incision in the cornea, which is then lifted up to remove the clouded lens in one piece.
- the inventive instrument of this application obviates the need for such an incision requiring only one incision in the form ofa small aperture to allow the opera tive end of the instrument to be inserted within the eye.
- the primary object of the present invention is to provide a vibratory instrument and method which are effective to break apart and remove soft, yielding material without the use of an auxiliary cutting medium and which is particularly adapted for use in restricted, enclosed sites, such as are encountered in surgical procedures.
- Still another object of the present invention is to provide an instrument including a handpiece having an operative tip capable of vibrating at ultrasonic frequencies with minute amplitudes and having both a source of fluid and a pumping line adjacent its working end, whereby particles of the material to be removed are dispersed within the fluid and withdrawn from the operative site through the pumping line as they are produced so that further cleaning is unnecessary.
- Another object of the present invention is to provide suitable power and fluid supplies and pumping means for use with such a handpiece, together with switch means for their control.
- a further object of the present invention is to provide various operative tip configurations for use with such a handpiece whereby removal of materials from relatively inaccessible locations is facilitated.
- the present invention comprises an apparatus having a casing in which is mounted a vibratory assembly for converting electrical energy into high frequency mechanical vibrations which are used to break apart the unwanted tissue.
- a first passage for carrying a treatment fluid to the region where the vibrations are applied
- a second passage for carrying a suspension of unwanted material in said treatment fluid away from said region which constitutes the above-mentioned inaccessible place.
- the apparatus also includes a means for supplying electrical energy to said vibratory assembly for the energization thereof and a means for supplying the treatment of fluid to said first passage and a means of withdrawing said suspension from said second passage.
- the casing is adapted to be held in the hand, and the vibratory assembly includes a transducer, such as of the magnetostrictive or piezoelectric type, a removable operative tip and a connecting body in the form of an acoustic impedance transformer for supporting the operative tip and coupling the high frequency vibrations thereto.
- a transducer such as of the magnetostrictive or piezoelectric type
- a removable operative tip and a connecting body in the form of an acoustic impedance transformer for supporting the operative tip and coupling the high frequency vibrations thereto.
- a supply of treatment fluid such as a liquid providing a dispersion medium for the particles to be removed, is coupled through a first passage provided in the housing to an outlet adjacent the operative tip.
- a source of suction provided by a suitable pumping means, is coupled via a second passage within the housing to a point adjacent the operative tip.
- alternating electrical energy is ap plied to the transducer to set the operative tip in vibratory motion.
- the region adjacent the operative site is bathed or flooded with the treatment fluid while the pumping means is activated to withdraw fluid with suspended particles therein from the region.
- the high frequency action of the small area output end of the operative tool tip against the material to be removed rapidly breaks it apart into tiny particles, dispersion of which in the fluid medium is enhanced by the vibratory forces engendered in the medium.
- the pumping means is then effective to withdraw the resultant suspension from the region of operation.
- the material to be removed is not only broken apart into small particles, but completely withdrawn from its original location. No subsequent flushing or aspiration procedures are necessary.
- the operative tip has a bore through its center forming a part of one of the passages and there is a tubular sleeve coupled to the casing, surrounding a portion of the operative tip to form an annular space thereabout which is part of the other of said passages.
- the front portion of the casing referred to as a tubular sleeve
- This tubular sleeve includes a sheath which is composed ofa plastic material. Since this sheath is quite small in diameter, in order to minimize the size of the incision, it would be very difficult to manufacture it from any metallic substance and maintain the proper tolerances to provide for the annular space between it and the operative tip. Also, the resiliency of plastic is necessary to avoid any substantial dampening effect on the vibratory assembly should the sheath contact the operative tip. The heat resistant nature of the plastic material also avoids the transmission of any heat to the cornea from the sheath.
- valve and switch means for selectively operating the source ofelectrical energy, withdrawal means and a line to atmospheric pressure. This is particularly important with respect to an operation in the eye, since it is extremely important to be able to maintain the fluid pressure within the eye within certain limits.
- the vibratory assembly must be supported in some manner within the casing and this is effected by the use of resilient sealing means, an example of which are rubber O rings.
- resilient sealing means serve the dual purpose of supporting the vibratory assembly at approximately a node of longitu dinal motion so as to have a minimum effect on dampening the motion and also serve to define one of the fluid passages.

- FIG. 2 is an enlarged pictorial representation of the tool tip shown in use, to aid in explaining its action;

- FIGS. 5A through SI show various forms of operative tips for use with the instrument.
- FIG. 6 is a schematic diagram of the foot switch control means for the oscillator and pump valves.
- the invention will be described in terms of its use as a surgical instrument, particularly as applied to cataract removal. However, it will be un derstood that the principles of the invention are not so limiting, and the apparatus described is capable ofa wide variety of material breaking and removal applications, within and outside the medical field.
- the elements of the instrument of the inventi include a handpiece indicated generally at 10, which is of a size and weight as to be comfortably held in the hand and easily manipulated by the user.
- the handpiece 10 includes within its outer housing o casing, transducer means for converting high frequctcy electzical energy into mechanical vibrations of high frequency and small amplitude.
- the requisite high frequency alternating current electrical energy is supplied by a conven tional oscillator included in the unit indicated generally at 12.
- a wide range of frequencies is suitable, for example from 1,000 to 100,000 cycles per second.
- a convenient choice of frequency has been found to be approximately 25,000 cps which permits optimum selection of handpiece components, both with respect to overall size and effectiveness, and also is above the range of human hearing, eliminating annoying audible effects obtained at lower frequencies.
- the output of the oscillator in unit 12 is connected by a pair of leads enclosed within the conduit 14 and coupled through the end ofthe handpiece remote from the operative tip.
- the oscillator is provided with suitable frequency and amplitude controls, whereby the precise frequency of operation may be tuned over a range and the amplitude of the electrical signals also may be varied. These controls enable tuning of the instrument to resonance and adjustment of the vibration amplitude ofthe operative tip, in accordance with the needs ofthe user.
- the unit l2 also provides a source of cooling water for the handpiece which ordinarily is required to carry away the heat generated by the electrical-to-mechanical energy conversion occurring in the handpiece.
- the conduit 14 also carries a pair of flexible tubes, one for carrying the coo lant into the handpiece end and the other for withdrawing the coolant therefrom.
- This provides a circulating system for maintaining the temperature of the handpiece at comfortable levels.
- Unit l2, as illustrated, is provided with a water control valve for adjusting the cooling flow.
- the coolant may be obtained from a convenient tap or may be incorporated in a closed circulation system having a small pump and a cooling system for the coolant returned from the handpiece.
- the supporting equipment for the handpiece further includes a pump R6 (to be referred to as a withdrawal means) and a treatment fluid supply 20.
- the pump is coupled via conduit l8 and through an opening in the housing of the handpiece to the interior thereof.
- the pump includes valve means whereby the conduit 18 may be selectively coupled to the pump or opened to atmospheric pressure.
- the treatment fluid supply 20 which may include a reservoir of a premixed solution of appropriate type and a suitable pump, or mixing means whereby the required solution is prepared on a continuous basis, is connected through conduit 22 and into the interior of the housing of the handpiece.
- the handpiece includes internal fluid passages coupled to the conduits l8 and 22 whereby, at the operative tip of the instrument, there may be provided both a flow of treatment fluid and a withdrawal of unwanted particles suspended in the treatment fluid.
- a switch 2 3 is provided to enable control of the oscillator and pump during manipulation of the handpiece by the sur geon.
- the switch 24 may be of any convenient type, preferably resting on the floor and including a control lever 25 adapted to be actuated by the foot selectively between several positions.
- the switch is coupled via conductors 26 to the oscillator housing 12 and the vacuum pump 16 to control the components thereof, as will be described more fully hereinafter.
- FIG. 2 The manner in which the instrument is used for tissue removal is illustrated in FIG. 2.
- 32 indicates a cohesive mass (as distinguished from a collection of discrete particles) of undesired tissue located within a region of healthy tissue 30 below the skin 34.
- a small surgical incision 36 is made through the skin adjacent the mass 32 to enable the operative tip of the handpiece 10 to reach the tissue mass 32.
- the surgeon ac tuates the foot switch 24 to apply alternating current power to the instrument to set the tip into vibration and also to actuate the pump 16.
- the treatment fluid supply is turned on, at controlled pressure, so that at the operative tip of the tool which is brought into contact with the mass 32, three conditions simultaneously obtain.
- the operative tip vibrates at a high frequency rate and with small amplitude against the tissue mass 32 and in the process breaks it apart into minute particles.
- the treatment fluid supply which preferably is a solution compatible with the animal tissue being treated (such as saline), floods or bathes the region at the tip end which is being subjected to the vibratory action.
- the suction source at the operative tip simultaneously withdraws from the operative site the resultant suspension of the small particles of removed tissue in the treatment fluid bathing the area.
- the surgeon manipulates the handpiece 10 until all of the unwanted tissue has been broken apart and removed from the operative site. If necessary, additional small incisions 36 may be made at various other surface points to permit ready access to the mass of unwanted tissue. However, each of these incisions need be only sufficiently large to admit the slender operative tip of the instrument. This reduces trauma and speeds recovery time, as compared to a massive surgical excision by the usual procedures.
- the handpiece itself is shown in cross section in FIGS. 3 and 3A. Substantially all of the operative parts of the handpiece are enclosed within a casing indicated at 40, which includes a generally tubular barrel section 40a, a smaller diameter extension section 40b threaded onto the forward end of the barrel 40a, a forward end cap 400 having a small diameter tubular portion extending therefrom (see FIG. 3A) threadedly engaging the forward end of extension 40b, and a rear closure 40d threadedly engaging the rear portion of the barrel 40a.
- all of the portions of the casing 40 are made of a metal such as stainless steel, which is sterilizable and which also provides shielding for the electrical and magnetic components within the handpiece.
- the vibratory assembly contained within the casing 40 is composed of a transducer portion 42 and a connecting body 46, the latter preferably in the form of an acoustic impedance transformer.
- the transducer element 42 may be of any suita ble type capable of converting high frequency alternating current signals into corresponding longitudinal mechanism vibrations.
- the transducer is composed of a stack of thin sheets of magnetostrictive material such as nickel, Permendur, or other similar material, insulated from each other and firmly secured together such as by brazing at the ends. As shown, the stack is divided by a lengthwise elongated opening effectively separating the stack into two separate vibratory sections, with the coil 44 wound about each section or leg separately, in such fashion as to produce in phase vibration in both legs.
- the forward end of the stack 42 is coupled, such as by a threaded connection as shown or by a permanent bond, to the input end of the connecting body 46.
- a washer 43 is provided between the end of the stack and the input surface of the member 46 to render the transmission of vibratory energy to the member 46 more effective.
- the connecting body 46 preferably is in the form of an acoustic impedance transformer whereby the amplitude of the longitudinal vibrations induced in the stack 42 may be increased for application to the operative tip of the handpiece.
- the member 46 may be of the type shown in US. Pat. No. 25,033, assigned to the present assignee, formed of a single piece of vibration transmitting material such as Monel metal, having a relatively massive input section 46a and a relatively slender output section 4612, with a tapered transition region 46c.
- maximum amplification of longitu dinal vibrations in such a member occurs when both the input and output sections of the transformer are equal in length to one-fourth of the wavelength in the material at the frequency of vibration and each of said sections is substantially uniform along its length in cross-sectional area.
- sufiicient amplitude of vibration may be obtained under less than maximum amplitude conditions. Accordingly, it will be understood that a relatively wide variation in dimensioning of the impedance transformer 46 is permissible to allow the instrument to perform its intended function effectively. in fact, many different types of connecting bodies may be employed.
- nodes of longitudinal motion would occur approximately midway along the length of the stack 42 and approximately at the junction of the input section 460 and output section 46b of the transformer.
- the effects of the high stresses at the junction are minimized by providing the tapered transition 46c.
- mounting means located approximately at a node of longitudinal motion whereby minimum damping of such motion results.
- such mounting means are provided in the form of a pair of resilient rings, generally referred to as 0" rings, located in a pair of spaced grooves extending circumferentially around the input section'46a of the transformer, as close as possible to the transition region where the nodal plane would be located.
- the rings 48 and 50 are of such diameter that they effect a fluidtight seal between the surface of the transformer input section 460 and the inner wall of the housing barrel 40a.
- a plurality of screws 52 are provided angularly disposed about the axis of the casing, for the purpose of preventing longitudinal or rotational movement of the vibratory structure within the casing and also for radially centering the vibratory structure within the casing.
- the sealing rings 48 and 50 divide the interior volume of the housing 40 into three independent fluid chambers.
- the ring 48 in conjunction with the end closure means to be described hereinafter will form a first chamber in which are disposed the magnetostrictive stack 42 and a portion of the transformer input section 46a.
- An annular chamber of relatively short axial dimension is formed between the two O-rings 48 and 50, and a third chamber is formed forwardly of the ring 50 including the free space within the casing extension 40b.
- the rear portion of the casing barrel 40 is sealed off by means of a grommet 55 which is press fitted into the end of the barrel to form a watertight seal therewith.
- the grommet is provided with openings through which the electrical leads 45 pass from the conduit 14 to the coil 44.
- a coolant fluid inlet tube 54 passes through the grommet 52 and extends within the barrel 40a to a point adjacent the forward end of the stack 42.
- Fluid outlet tube 56 is also passed through the grommet 52 and into the conduit 14 along with the tube 54.
- the cooling water supply continually flows into the chamber enclosing the magnetostrictive element from the tube 54, and is withdrawn through the outlet tube 56 after passing over the heat producing elements. It will be understood that the leads 45 and conduits 54 and 56 pass through the grommet 52 in fluid tight relationship.
- a wire coil 15 may be wrapped around the portion of the conduit 14 adjacent the handpiece, in place of the plastic tubing enclosing the remainder of the conduit.
- the coil 15 engages a helical groove provided internally of a retaining element 41. The latter element is compressed about the coil 15 and firmly retained against movement by the threaded cap 40d.
- the impedance transformer 46 is provided with an axial bore 47 extending from the free or forward end of the output section 46b and into the input section 460, to a point between the two sealing rings 48, 50.
- a radial bore 47a connects the bore 47 to the periphery of the transformer 46 and into the annularchamber between the sealing rings.
- Nipple 56 is connected to the periphery of the handpiece barrel we and is provided with an internal bore extending through the casing and communicating with the annular chamber between the rings 48 and 50 and thus with the bore 497 via the radial bore 470.
- a second nipple 58 is connected to the casing extension 30]; at a point near its threaded coupling to the barrel 40a.
- the latter nipple includes an internal passage communicating with the annular chamber extending forwardly of the sealing ring 50 and including the space between the impedance transformer 46 and the inner walls of the casing sections. As shown best in FlG 3A, this latter chamber extends past the free end of the output section of the connecting body 46b and through the cap Mic.
- the operative tool or tip which actually comes into contact with the material to be broken apart and removed is designated by the numeral 60.
- the tip (at) is elongated and provided with a thickened shank portion 604: which preferably is formed with at least a pair of flats to accommodate a wrench for tightening.
- a threaded connection portion MM is formed integrally with the base portion 60a, and a washer 600, of efficient vibration-transmitting material, is disposed adjacent the shoulder between the portion 60a and 60b.
- the other end of the tip 60 is shaped in a manner dependent upon the particular type of material or tissue to be broken apart and removed and the shape of the portion to be removed or its surrounding material.
- an acute-angled taper is provided to leave a relatively sharp, rounded edge 60d.
- An axial bore 6th? extends completely through the tip 60 to provide a fluid passage from threaded end 60! to the outer or working end ofthe tip.
- the bore 47 in the transformer 46 is provided at the free end of the output section with internal threads adapted to receive the threaded portion 60b of the tip (it).
- the end cap 400 is threadedly disengaged from the casing extension 40!; and slid backover and away from the tip 6Q.
- a small wrench may be used to engage the flats on the base section 60a to remove a tip already in place or to snugly in rt anew tip. The end cap 400 is then replaced and the tool is assembled for use.
- the operative tip 6'1 preferably is formed of an extremely hard, sterilizable material, such as titanium, and for most surgical applications is made of extremely small dimension.
- the operative tip had an outside diameter of approximately 1 millimeter. Since this is the only portion of the instrument that is brought into contact with the tissue to be broken apart and removed, it will be evident that only a very short incision need to made in the outer surface to permit access of the tip.
- a sheath 64 of a strong, heat-resistant and inert material such as the plastic known as Teflon.
- the sheath 64 is provided with an axial bore of a diameter somewhat greater than the outer diameter of the tip 60 and has a base section with a counterbore that snugly engages the tubular portion extending from the forward end of the end cap 400. The fit between the latter two parts is made such that the sheath 64 may be secured to the end cap 400 with manual pressure but will not shake loose under normal usage.
- the barrel of the sheath 64 extends along a considerable length of the operative tip 60 and has an outer diameter of sufficient thickness to provide the necessary structural rigidity. Preferably, it is slightly tapered, as shown.
- the annular clearance between the inner surface of the sheath s4 and the outer surface of the operative tip 60 serves as an extension of the fluid passage formed between the transformer section 46); and the casing extension 40)).
- alternating current electrical energy having a superimposed direct voltage bias thereon is coupled from the unit 12 and via conductors 45 to the coil on the transducer 42.
- the vibratory structure is thereby set into longitudinal vibration at the oscillator frequency, with the consequent vibration of the operative tip 6h.
- the amplitude of the alternating current supply may be set such that the work ing end of the tip 6 0 has a stroke amplitude of approximately 0.003 inch.
- a coolant supply is circulating in the chamber housing the transducer structure.
- treatment fluid from the supply 2b is provided through the conduit 22 and the nipple 53 to the passage formed between the connecting body 46 and the casing extension 40b and thence through the annular space between the cap 400, sheath 45 i, and the tip 60.
- the tissue adjacent the operating tip is thereby bathed with the treatment fluid.
- the treatment fluid serves two purposes. in addition to maintaining the operative tip relatively cool during use, thereby reducing possible harm to healthy tissue, it provides a dispersion medium in which particles of tissue are suspended as they are broken away from the tissue mass. it will of course be realized that the treatment fluid is being brought into direct contact with delicate tissue and accordingly must be of a neutral nature. In the case of cataract removal, for example, a balanced isotonic saline solution is suitable for this purpose.
- FIG. 4 A portion of a simplified cross section of a human eye is shown to illustrate the manner in which the device is employed.
- the opaque lens or cataract which is to be broken apart and removed to is designated by the numeral 72 and is encased in a membrane including an outer portion 72a known as the anterior capsule and a rear portion 7211 known as the posterior capsule.
- the iris is designated by the numeral '74 and the major gel-filled portion of the eye, or vitreous, is shown at 76.
- the cornea, the transparent outer surface of the eye, is shown at 70.
- suitable drugs are administered to dilate the iris to its maximum extent, so that as much of the anterior capsule 72a is exposed as is possible.
- a small incision 78 is then made in the transparent cornea fluid as far as possible from the center of the pupil area. This incision need only be about l to 3 mm. in length to provide proper access for the operative tip ofthe vibratory assembly.
- the anterior capsule 72a is penetrated, first, either by the operative tip of the vibrating assembly or with a surgical in strument. Once an opening in the anterior capsule has been made, such as indicated in FIG. 4, the operative tip is inserted into the body of the cataract 72, whereby the lens tissue mass is broken apart into minute particles. During this portion of the operation, the transducer is energized and the pump is activated to provide suction force at the operative tip, along with a supply oftreatment fluid.
- the remnants of the anterior capsule and the posterior capsule are withdrawn with capsule forceps. This completes the cataract removal.
- the small incision 78 is subsequently sutured to conclude the surgical procedure. As compared to the conventional cataract removal, which requires a 180 incision around the cornea, trauma to the patient and recovery time are substantially reduced.
- the operative tip of the vibratory assembly is illustrated as inserted into the eye with the plastic sheath 64 in place.
- the sheath also serves to discharge the treatment fluid more directly atthe operative site.
- the sleeve 64 may be removed and the operative tip employed without it where operative conditions permit.
- the treatment fluid supply serves a purpose in addition to providing a dispersion medium for the particles of unwanted tissue and a coolant for the operative tip, by serving to maintain sufficient pressure within the anterior chamber of the eye, between the anterior capsule 72a and the cornea 70, whereby collapse of the latter is avoided.
- the operative tip 60 shown in detail in FIG. A is but one of a number of different forms of operative tip that may be employed with the instrument of the present invention.
- the straight tapered tip shown in FIG. SA will not be able to reach all of the lens tissue within the lens membrane without incurring the danger of piercing the vitreous.
- operative tips having other shapes are employed. Several possible configurations for this and other purposes are shown in FIGS. 58 to SI.
- FIGS. 5B and 5C illustrate, respectively, a symmetrically straight tapered tip end and a symmetrically rounded taper tip end.
- FIGS. 5D and 5E are two views ofa tip having a relatively blunt end and an opening angled to the axis of the main portion of the tip to provide a spoon shape. Such a tip is used to reach the inaccessible corners of the lens capsule without risking damage to or possible puncture of the vitreous.
- FIGS. 5F and 5G and FIGS. 5H and SI show two additional forms of operative tips, each of which incorporates a sharp projection such as might be used for puncturing the anterior capsule of the eye.
- FIG. 6 A suitable switch control a arrangement for the oscillator and coolant supply 12 and the pump 16 (FIG. 1) is shown in FIG. 6.
- the pump 16 includes two input lines, 80 and 82, and a discharge line 92 to a drain or waste line.
- the pump preferably is of the continuous acting type and therefore is either pumping fluid from a sump or reservoir through input line 80 or from the operative site through the handpiece and conduits l8 and 82.
- Control of the conduits 80 and 82 is effected by solenoid valves 86 and 88 respectively, so that the pump is pulling fluid through one or the other at any given time.
- an additional conduit 84 is coupled to in the input line 82 under control of an additional solenoid valve 90.
- the switch 24, having a foot-actuated control arm 25, not only controls the operation of the pump 16 but also the application of energy from the oscillator in unit 12 to the coil on the handpiece transducer.
- the switch has three positions, A, B, and C, the position A having a pair of spaced contacts'94, the position B having a pair of spaced contacts 96, and position C having two pairs of spaced contacts 98 and 100.
- the switch arm 25 is pivoted at one end and includes a pair of spaced conductive segments 25a and 25b, separated by insulating material. When in position C, as shown in the drawing, the segment 25a bridges the contact pair 98 while the segment 25b bridges the contact pair 100. In positions A and B, the segment 25a bridges the contact pairs 94 and 96 respectively.
- a source of operating voltage 102 is coupled to one contact of each of the contact pairs 94, 96 and 98.
- the other contact of contact pair 94 is coupled to the inputs of both solenoid valves 86 and 90.
- the other contacts of pairs 96 and 98 are connected in common to the control input of solenoid valve 88.
- the contact pair 100 interrupts a lead from the oscillator 12 to the handpiece whereby energy is delivered to the latter only when the segment 25b bridges the contact 100, as shown.
- the switch arm 25 is spring urged, such as by a coil spring 104, so that its normal position is in position A, bridging contacts 94.
- Each of the solenoid valves 86, 88 and are normally in their closed position, that is, with no electrical power supplied to their control inputs, they close the channels in which they are interposed.
- valves 86 and 90 With the switch are in position A, the contacts 94 are bridged, permitting connection of the source 102 to both valves 86 and 90. These two valves are thus opened, connecting the pump input to the reservoir or sump and opening the conduit 18 to atmospheric pressure. The valve 88 remains closed.
- valve 88 With the switch arm in position B, bridging contacts 96, valve 88 is opened while valves 86 and 90 remain closed.
- the pump 16 then is coupled directly to the conduit 18 and thus provides a suction force at the tip of the handpiece. It will be noted, that in both positions A and B, the output of the oscillator 12 is not connected to the handpiece and consequently, the operative tip 60 is not set into vibratory motion.
- valve 88 With the switch arm in position C as shown, valve 88 is opened, valves 86 and 90 are closed and the biassed alternating current output of the oscillator is coupled to the hand piece. This establishes the full operative condition of the handpiece, i.e., high frequency vibration of the operative tip and the establishment of a suction force to withdraw fluid from the operative site.
- control of the treatment fluid supply will be maintained preferably by an assistant to the operating surgeon.
- the surgeon will direct the assistant to control the pressure of the fluid supply, between an Off" or no supply position and a High condition, under which maximum flow into the operative site is obtained. (See FIG. 1).
- the amplitude of the oscillator output will be controlled to produce the proper stroke amplitude at the operative tip. Adjustment of the latter is desirable to permit both removal in gross of unwanted tissue as well as the cleaning up of small bits of material where care must be exercised to avoid damaging surrounding tissue.
