Multi-purpose irrigation/aspiration pump system
First Claim
1. A multi-purpose irrigation/aspiration pump system for use with a source of irrigating fluid and with a source of aspirating vacuum during an endoscopic surgical procedure at a surgical work site comprising:
- an elongated fluid inflow conduit connected between said fluid source and the work site;
an elongated fluid outflow conduit connected between the work site and said vacuum source;
pressure producing means for producing a predetermined fluid pressure in said fluid inflow conduit;
aspiration regulating means for regulating the fluid flow in said fluid outflow line;
pressure sensing means for sensing the fluid pressure at a predetermined point in the flow path of said fluid;
control means responsive to said pressure sensing means for controlling said pressure producing means and said aspiration regulating means;
a tubing cassette housing means comprising;
an integrally formed planar body having a front surface and a back surface, a first channel formed in and parallel to said back surface for holding a predetermined intermediate portion of said fluid inflow conduit and a second channel formed in and parallel to said back surface for holding a predetermined intermediate portion of said fluid outflow conduit, said first and second channels being open on said back surface to enable direct access of said pressure producing means and said aspiration regulating means to said predetermined intermediate portions of said fluid inflow and outflow conduits;
coding means on said cassette housing means for containing a code which identifies at least one predetermined irrigation/aspiration operational characteristic;
decoding means for determining said code contained in said coding means and communicating same to said control means;
retention means for receiving said cassette housing means and operatively engaging said fluid inflow conduit with said pressure producing means and said fluid outflow conduit with said aspiration regulating means.

Abstract
An irrigation/aspiration pump system capable of operating in a plurality of different modes suitable for a variety of different endoscopic surgical procedures. The irrigation/aspiration pump system operates with a selected one of a plurality of tubing sets, each tubing set being adapted to provide irrigation and aspiration for a particular surgical procedure and coded to define the type of procedure for which the tubing set is designed. Each tubing set is adapted to be received by the irrigation/aspiration pump console in a way which enables the code associated with the tubing cassette to be automatically read by a code detecting means associated with the system. The code detecting means supplies appropriate control signals to different parts of the irrigation/aspiration pump system in order to assure that the parameters with which the system will be operating, when the chosen tubing set is being used, are those for which the tubing set is designed. A simplified one-piece cassette housing is utilized to retain a plurality of flexible conduits within predetermined positions relative to each other and relative to associated components of the pump system console.

5. A tubing set for use with an irrigation/aspiration console comprising:
-
a first flexible tube for supplying irrigation fluid from a fluid source to a first predetermined location; a second flexible tube for communicating a reduced, aspirating pressure from a source of reduced pressure to a second predetermined location; a flat housing for receiving predetermined intermediate portions of said first and second tubes therein, said housing having parallel front and back surfaces and comprising respective first and second channel means in said back surface for holding said predetermined intermediate portions of said first and second tubes in predetermined positions relative to each other, said first channel means comprising a pair of laterally spaced first channel sections extending entirely across said back surface and adapted to hold said first tube therein with a portion thereof extending beyond the periphery of said housing, said second channel means comprising a semi-circular second channel section, the ends of which are laterally spaced from each other and disposed parallel to and inwardly of said spaced first channel sections. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16)
