An irrigation system for use during endoscopic or minimally invasive surgery is shown. Both vacuum and a pressurized irrigation fluid are continually provided to a trumpet valve for immediate use during surgery. A pump that provides the pressurized irrigation fluid has a reusable motor, but a disposable head that can be replaced between procedures. A control circuit automatically reduces the voltage being supplied to the pump if there had not been a request for irrigation fluid for a first time period. If a second time period, which is longer than the first time period, passes and (a) there is no demand for irrigation and (b) the voltage to the pump has not been reduced, either the voltage to the pump will be reduced or the pump shut OFF. The irrigation system is provided in kit form with parts having to be replaced between procedures contained therein.
1. An irrigation system for use during endoscopic surgery on a patient comprising:a vacuum source; a source of irrigation fluid; a trumpet valve for alternately connecting said vacuum source or said irrigation fluid to said patient during said laparoscopic surgery according to demand by the user, a
1. An irrigation system for use during endoscopic surgery on a patient comprising:a vacuum source; a source of irrigation fluid; a trumpet valve for alternately connecting said vacuum source or said irrigation fluid to said patient during said laparoscopic surgery according to demand by the user, a first button of said trumpet valve providing said irrigation fluid from said source to said patient, a second button of said trumpet valve providing suction from said vacuum source to said patient; a pump between said trumpet valve and said source of said irrigation fluid to continually provide said irrigation fluid under pressure to said trumpet valve during said laparoscopic surgery; and a vacuum cannister between said vacuum source and said trumpet valve to collect fluids or particles therein during said suction; said pump including a disposable head and a reusable motor with a quick disconnect therebetween.
