Abstract
An endoscopic surgical instrument 20 includes an irrigation port 21 and an evacuation port 22. Each port, 21 and 22, is connected through independent valves 23 and 24, respectively to a single access conduit 25. The connection between the valves 23 and 24 and conduit 25 is along connector tubes 23a and 24a. The access conduit 25 leads from the valves and their respective valve conduits to a probe connector 26. This probe connector 26 is designed to receive one end, the locating end 27, of a surgical probe 28 which would be used during microsurgical procedures. The surgical instrument 20 also includes a port 31 which allows the surgeon to insert microsurgical instrumentation (not shown) along the access conduit 25 and the bore of the hollow probe 28 to exit from the end 32 thereof. The port 31 should provide a fluid-tight seal when no microsurgical instrumentation is being used with the surgical instrument 20. This will prevent fluid which may be moving along the access conduit 25 to or from the patient, from leaking.
