Publication number: 20230329776Abstract: An electrosurgical instrument has a movable tissue cutting mechanism, a shaft housing at least a portion of the movable tissue cutting mechanism, and a pair of opposing jaws rotatable relative to the shaft. Each jaw has an electrically conductive core member, a slot for receiving the cutting mechanism, and a sealing surface. A pin is coupled to the shaft and the jaws. The pin passes through the jaws and the cutting mechanism. A first link is rotatably coupled to the first jaw and a rod. The rod is interior of and translatable relative to the shaft. Each jaw has a coating made of a substantially non-conductive material covering a portion of the conductive core member but exposing the seal surface, whereby the coating limits an energy path from the respective conductive medium to the respective seal surface.Type: ApplicationFiled: June 21, 2023Publication date: October 19, 2023Applicant: BOLDER SURGICAL, LLCInventors: Joseph D.
