Abstract:
1. A method of removing tissue from a patient utilizing an electrosurgical instrument, the method comprising: providing an electrosurgical instrument having a pair of opposing end effectors, only one of the end effectors including a conductive cutting portion and the other of the end effectors including an opposing portion; positioning the conductive cutting portion on one side of the tissue to be removed and positioning the opposing portion on an opposing side of the tissue to be removed; causing relative movement of the end effectors toward each other to define a direction of movement; constraining the tissue to be removed between the conductive cutting portion and the opposing portion; providing electrosurgical energy to the conductive cutting portion; discharging electrosurgical energy to the tissue ; dissecting the tissue through a combination of the electrosurgical energy discharged to the tissue and the conductive cutting portion; cauterizing the tissue through the electrosurgical energy discharged to the tissue; moving the conductive cutting portion to a position where the opposing portion has slipped past the conductive cutting portion the conductive cutting portion defining only a portion of a lateral extent of the end effector that includes the conductive cutting portion; performing the dissecting and cauterizing steps while constraining the tissue between the conductive cutting portion and the opposing portion; and removing the dissected tissue from the patient while constraining the tissue between the end effectors.
