Laparoscopic apparatus for performing electrosurgical procedures
First Claim
1. A system for irrigating a surgical site during an electrosurgical procedure, comprising:
- a hand piece having a housing with a multi-lumen tube extending therefrom and an electrode operatively associated therewith disposed in electrical communication with a generator, the multi-lumen tube including an irrigation tube configured to deliver irrigation fluid and a suction tube configured to withdraw irrigation fluid, the irrigation tube coupled to an irrigation fluid source and the suction tube coupled to a vacuum source, each of the irrigation tube and suction tube disposed in fluid communication with an irrigation tip having at least one outlet defined therein that supplies irrigation fluid and at least one inlet defined therein that withdraws irrigation fluid,wherein the at least one inlet is distal relative to the at least one outlet with respect to the irrigation tip, the disposition of the at least one inlet opening permitting irrigation fluid to flow along a larger segment of the electrode thereby maximizing the transfer of heat from the electrode to the irrigation fluid.

Abstract
A system and apparatus for irrigating a surgical site during an electrosurgical procedure are disclosed. The system includes a hand piece having an elongated housing connected to a multi-lumen tube extending proximally from the housing and having an irrigation tube for delivering irrigation fluid, a suction tube for withdrawing irrigation fluid, and electrical wiring, a first controls for adjusting flow of irrigation fluid within the irrigation tube and second controls for adjusting flow of irrigation fluid within the suction tube. A valve cassette is connected to the multi-lumen tube, which includes an irrigation valve configured to control the flow within the irrigation tube and a suction valve configured to control the flow within the suction tube. A hardware control module controls the irrigation valve and the suction valve based on control signals from the first and second controls.

11. A system for irrigating a surgical site during an electrosurgical procedure, comprising:
-
a generator; an electrode; a hand piece adapted to selectively couple to the generator and in operable communication with the electrode, the hand piece having a housing with a multi-lumen tube extending therefrom, the multi-lumen tube including an irrigation tube adapted to couple to a fluid source and a suction tube adapted to couple to a vacuum source; and an irrigation tip having at least one outlet defined therein that supplies irrigation fluid and at least one inlet defined therein that withdraws irrigation fluid while the electrode is active, the irrigation tip in fluid communication with each of the irrigation tube and suction tube, the at least one inlet is distal relative to the at least one outlet with respect to a distal tip of the irrigation tip, the disposition of the at least one inlet permitting irrigation fluid to flow along a larger segment of the electrode thereby maximizing the transfer of heat from the electrode to the irrigation fluid. - View Dependent Claims (12)
