Patent number: 10729488Abstract: A bipolar electrosurgical instrument includes first and second shafts each having a jaw member extending from its distal end. Each jaw member is adapted to connect to a source of electrosurgical energy such that the jaw members are capable of selectively conducting energy through tissue held therebetween. A knife channel is configured to reciprocate a cutting mechanism therealong. An actuator selectively advances the cutting mechanism. A switch is disposed on the first shaft and is configured to be depressed between a first position and at least one subsequent position upon biasing engagement with a mechanical interface disposed on the second shaft. The first position of the switch relays information to the user corresponding to a desired pressure on tissue and the at least one subsequent position is configured to activate the source of electrosurgical energy to supply electrosurgical energy to the jaw members.Type: GrantFiled: February 7, 2019Date of Patent: August 4, 2020Assignee: COVIDIEN LPInventors: Ryan C. Artale, Jeffrey M. Roy, Tony Moua, Dennis W. Butcher, William J. Dickhans, Daniel A. Joseph, Luke Waaler, Cynthia M. Perry, Meghan Collins Long
