INVENTOR. JOHN CIRILLO ATTORNEYS INCISION IRRIGATOR FOR USE DURING SURGICAL PROCEDURES FIELD OF THE INVENTION The present invention relates to surgery and more particularly to an instrument used by a surgeon during an operation to wash away blood, body fluid and the like so that the surgeon's vision of the affected area will not be obscured.
SUMMARY OF THE INVENTION An object of the present invention is to provide an incision irrigator which is relatively simple in construction.
Another object is to provide such an irrigator which is readily operated in an efiective manner.
A further object is to provide such an irrigator which is compact in construction yet has a relatively high output at a substantial pressure.
Other and further objects will become more apparent upon reference to the following specification and annexed drawing.
In accordance with the present invention, the foregoing objects are generally accomplished by an incision irrigator which comprises a deformable tube having an inlet end and an outlet end, a check valve at each of the ends, piston means for deforming the tube between the ends thereof, and means for reciprocating the piston means to pump liquid through the tube.
BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a side elevational view, partly in section, illustrating an incision irrigator in accordance with the present invention.
FIG. 2 is an end view of the irrigator as seen substantially along the line 2-2 of FIG. 1.
DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawing in detail, there is shown an incision irrigator or pump which generally comprises a body 10, a deformable tube 11 removably supported by the body, and mechanism generally indicated by the reference numeral 12 for deforming the tube.
The body includes a handle section 14 for grasping the instrument by hand during the use thereof.
The tube 11 has an inlet end provided with acheck valve 15 and has an outlet end provided with a check valve 16. The tube is constructed of soft sterile plastic which is readily deformed. After each use of the instrument, the tube is disposed of and a new tube is installed the next time the instrument is used. As shown in FIG. 1, the inlet end is submerged in a body of liquid such as a sterile saline solution 17.
The mechanism 12 includes a piston 18 mounted for reciprocation in a cylinder 19 within the body 10, a conventional gear train 20 having an output eccentric 21 connected by a rod 22 to the piston and having a toothed input wheel 24, a hand-operated lever 25 pivotally mounted on the handle section 14 and having toothed rack 26 meshing with the wheel 24 to rotate the same, and a return spring 27 for the lever. As shown in FIG. 2, the wheel driven by the lever drives the gear train through means such as a ratchet arrangement 28 for preventing operation of the gear train during the return stroke of the lever. The output to input ratio may be 100 to I.
In use, each upward stroke of the piston 18 squeezes the tube 11 between its ends, for example at 29, to drive a pulse of liquid through the check valve 16, and during the return stroke of the piston, liquid is drawn into the tube through the check valve 15. The instrument preferably is arranged to deliver pulses of liquid at a rate of about 20 per second and at a pressure of about 60 PSI. Each stroke of the lever 25 should cause liquid to be delivered for about 1 to 2 seconds, and the rate of liquid delivered should be about 500 cc per minute.
SUMMATION From the foregoing description, it will be seen that the present invention provides a simple and practical incision irrigator which pumps and delivers liquid in an efl'ective manner.
While a preferred embodiment of the invention has been described, it will be understood that it is illustrative only, and the invention is limited solely by the appended claims.
