Abstract
Abstract A multiple purpose medical forceps allows for simultaneous grasping of tissue while lasing, irrigating, suctioning and cauterizing. The forceps includes a laser fiber and irrigation and suction catheters contained within a tubular housing and exiting adjacent a pair of jaws. The forceps is insertable through a cannula into a patient's abdomen for use during a laparascopy, or into any other bodily cavity where scopic surgery may be performed.
