Definitions
- ABSTRACT A vacuum curet for use with uterine aspirator apparatus.
- the curet has a cannula barrel with a suction port at one end, and a manifold or handle at the other.
- a capillary runs along the inner length of the cannula barrel terminating at the cannula tip at one end and at the manifold at the other.
- the entire length of the capillary is pressure-tight.
- the design permits introduction of appropriate fluid into the uterus at any time during the operative procedure. Introduction of the fluid may be accomplished in different ways. One way is to apply manual pressure on a squeeze tube connected either directly (or indirectly through tubing) to the curet manifold. Alternatively, a standard syringe is used in place of the squeeze tube. I 1 Y 10 Claims, 3 Drawing Figures f'ATENTEU HR 18 I974 INVENTOR.
- the invention relates generally to medical equipment and particularly to vacuum cannula apparatus used in uterine aspiration.
- the technique is to aspirate the conceptus from the uterus using a tube which has a flexible connection to a source of suction.
- a typical apparatus includes a suction curet having an oval mouth at its end, or on-one side, and an air hole at the other end to control the suction.'
- a rubber pressure tubing connects the curet to a transparent, e.g., glass, container which in turn is connected to a suction pump. Aspriation of the uterine contents usually takes less than 2 minutes and the debris can readily be seen as it appears in the glass container.
- the method employed may be very briefly reviewed.
- the perineum, vagina, and cervix are disinfected.
- the cervix is then drawn forward with a vulsella.
- the direction of the cervical canal and the depth of the uterine cavity are determined with a uterine sound.
- dilation may be unnecessary in certain cases, and when not needed, an anesthesia generally is not used.
- a local or general anesthesia is administered.
- the suction curet of appropriate diameter and design is inserted carefully into the cervix. The suction is then started.
- the suction reaches the working level which typically is at a mean level of 18 inches of mercury (relative).
- the suction curet is moved gently up and down over all aspects of the uterine cavity.
- the debris from the conceptus passes visibly into the glass container, either whole or piecemeal.
- the degree 'of suction can be controlled with some aspirators by putting a thumb over an airhole in the handle of the curet as well as by using some devices on the pump.
- the uterus reacts by contracting and decreasing volume. Aspiration usually takes less than 2 minutes. It is though to be complete when the uterine wall feels smooth and no further debris emerge.
- a typical apparatus used for uterine aspiration consists of a curet connected by a hose to collection bottle which in turn is connected by a second hose to a vacuum pump.
- An improved apparatus is shown and described in my copending U.S. Pat. application Ser. No. 63.480 have been described.
- the curets are usually made from metal or from converted strong urethral catheters.
- the advantage of metal is that for a given internal diameter, the external diameter can-be less because of the strength of the material.
- transparent curets of either glass or plastic, e.g., plexiglas are popular because cleanliness is obvious and debris can be seen passing through during operation.
- Each aspirator apparatus is outfilled with several suction curets of different sizes, and sometimes, design.
- Curets have been used with oval openings both on the side and on the end to facilitate clearing the cornea.
- a four opening at the working end curet has been described.
- a double tube curet in which sterilized water (30-50ml/min)irrigates the uterus from the cavity between the tubes while the debris passes down the inner tube, has also been described.
- the average curet is 25 cm long with external diameters ranging from 3.5 mm to 15 mm with a mode of about 8 mm.
- the larger diameter'curets are used for later pregenancies.
- the above cited D. Kerslake and D. Casey article reviews various types of curets.
- the apparatus for introducing the medicinal fluid be uncomplicated, and not require large amount of plumbing and hoses in the operating room, and if possible, not require a nurse or other operating room attendant for its proper functioning.
- a further requirement of the equipment used for introducing medicinal fluid during a vacuum currettage is that it be sterile, because the fluid is introduced into the patient. Reservoir sources, while traditionally sterile, may become contaminated when they are introduced with pumps and piping or plumbing necessary for introducing the fluid.
- a surgical fluid reservoir in a plastic squeeze tube which is mounted adjacent to the handle of the curet.
- a capillary tube extends from the sqeeze tube reservoir along the inside ofthe curet to a capillary tip opening near the end of the cannula adjacent to the suction port.
- the surgeon may introduce more or less fluid by squeezing the tube and thus adjusts the flow of fluid in the course of the'operation. With this arrangement, the surgeon has complete control over the introduction of the surgical fluid.
- Thecannula is of course, sterile prior to the operation, having been autoclaved, and the fluid source in the squeeze tube may be prepared under sterile conditions.
- the attachment of the squeeze tube to the can- 'nula may be done with a sterile coupling, and typically a Luer lock connection may be used.
- the mating half on the squeeze would be sterile, and covered with a cap or other plastic member to insure its not being contaminated. Thus, the sterile condition of the medicinal fluid is insured, and the chance of contamination is minimized.
- the medicinal fluid is introduced by the surgeon himself, and it is not necessary to have an operat-' ing room attendant regulate the introduction of a medicinal fluid through an external pump or other pressure-introducing means. Furthermore, it is not necessary to have pumps or complicated equipment in the operating room for the introduction of the medicinal fluid, and the hoses and interconnections between such pumps and the curet are also avoided.
- a standard syringe is mounted on the curet adjacent the handle.
- a standard syringe is mounted on the curet adjacent the handle.
- between five and twenty cc of distilled water, or other medicinal fluid having an antiseptic and/or analgesic properties are routinely introduced.
- the surgeon would pause for a moment, depress the plunger on the syringe to force the fluid into the uterus, and then continue the operation to remove the injected fluid.
- the fluid reservoir source is mounted on the curet and may be discharged by the surgeon himself without the mandatory assistance ofa nurse and withoutrequiring additional pumping of liquid handling apparatus in the operating room.
- the cannula is of a novel design having a very small diameter capillary tube extending down the inside wall of the cannula barrel.
- the capillary tip is located proximate to the port but further towards the end of the cannula and closer to the opposite side of the cannula.
- a further application of the cannula of this invention is in the use of abortions performed during the second trimester. Vacuum is considered to be less and less effective after the 12 week of pregnancy. Abortions by saline injection seems safer and more effective after this period. Saline injection is accomplished by withdrawing an appropriate amount of amniotic fluid surrounding the fetus and replacing it with an equal amount of saline solution, which induces abortion by natural means.
- the basic cannula, connected to a suitable saline source may be used for this technique.
- the cannala barrel under vacuum is used to withdraw the amniotic fluid and then after the vacuum has been shut off, the saline solution is introduced into the uterus through the capillary.
- FIG. 1 is a perspective view of a vacuum curettage apparatus having the vacuum cannula of this invention.
- FIG. 3 is an end view of a portion of the vacuum cannula apparatus of FIG. 2.
- FIG. 1 there is shown a perspective view of a vacuum curettage apparatus, in which there is shown a curet generally indicated at 10 connected by a hose 12 to a collection bottle 14, which in turn is connected by a. second hose 16 to a vacuum pump 18.
- the collection bottle is of an improved kind, shown and described in detail in my copending US. Pat. application Ser. No. 63,480 filed on Aug. I3, 1970.
- a standard 50 cc syringe 20 is shown attached to the curet 10.
- the syringe is shown attached to'the handle 22 of the curet and makes ,a communicating path with a capillary tube extending down the barrel of the curet to its tip.
- curet 30 is shown adjacent to the curet 10. It is similar to curet 10 but of slightly different dimensions. It is customary to employ different size'currets depending upon the needs of the operation. It will be noted that the curet 30, just beyond the handle,' has two connectors: one connector 32 is to be made with the hose 12, the second connector 34 is to be made to the standard syringe.
- FIG. 2 a side view of an alternative embodiment of the curet of the present invention, and in FIG. 3, an end view of the tip of the curet shown-in FIG. 2 and taken along lines 3-3.
- the curet includes a cannula barrel 40 having a suction port 42 near one end.
- a capillary 44 extends along the inside length of the cannula barrel.
- the capillary terminates at its outer end in a capillary tip opening 46, which extends through the wall of the cannula barrel. This is shown in both FIGS. 2 and 3.
- the capillary tip opening is near the suction port, and as shown in the figure, is preferably further towards the end of the cannula than the suction port, and located on the side away from the port.
- the inside of the cannula barrel extends through the manifold to a tapered fitting 50.
- the other end of the handle 52 is provided with a coupling 54 suitable 'for interconnection with a hose which leads to a collection bottle.
- An optional vacuum control hole 56 is shown in the handle communicating with the hollow interior. The surgeon may regulate the pressure in the operating area by placing his thumb partially or wholly over this hole 56.
- interchangeable handle is shown as part of the path leading from the suction port through the cannula barrel to the vacuum collection system. It should be appreciate that fixed handles may be employed, such as those shown in FIG. 1, or curets with handles that are not in the suction flow path may also be employed.
- a squeeze tube fluid reservoir 62 is shown having a mating Luer lock connection attached to the manifold connection 60.
- the medicinal fluid is prepared and stored in the squeeze tube fluid reservoir 62.
- the fluid is sterile and the Luer lock connection 64 is also sterile and initially covered with a protective material.
- the cannula barrel and manifold are also sterile.
- the protective material (not shown) is removed from the Luer lock connection 64 and the squeeze tube fluid reservoir is attached to the manifold by the connectors 60, 64.
- the surgeon squeezes the tube reservoir 62 slightly, to force the fluid through the port 58 and capillary 88 until a small amount of fluid emerges at the capillary tip opening 46. This is to make sure there is no air in the capillary tube and to insure that no air is introduced into the uterus during the operation.
- the reservoir has been shown attached to the curet by a standard Luer lock connection 60, 64. It should be appreciated that any convenient or conventional locking means may be employed.
- a curet apparatus has been constructed in accordance with the teaching of this invention and the following dimensions for that curet are set forth below. it should be understood however, that these dimensions are for purposes of dimensions only and variations may be made therefrom without departingfrom the spirit or scope of the invention.
