Publication number: 20230054962Abstract: A forceps includes an end effector assembly having a stop and a plurality of overmold teeth within at least one jaw member. One (or both) of the jaw members is moveable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween. One (or both) of the jaw members includes a stop molded within an insulative housing, and an insulator plate with the overmold teeth formed from plastic. The overmold teeth extend through openings within a sealing plate and protrude past the tissue sealing surface of the sealing plate. The stop primarily controls the gap distance between opposing jaw members by bearing most of an applied load and the overmold teeth assist in controlling the gap distance by bearing the remaining applied load.Type: ApplicationFiled: November 7, 2022Publication date: February 23, 2023Inventors: John R. Twomey, Dylan R. Kingsley, James D. Allen, IV, Sean T. O'Neill, Jeffrey M. Roy

Patent number: 11103302Abstract: A forceps includes a housing having a shaft. An end effector assembly operatively connects to a distal end of the shaft and includes a pair of first and second jaw members. One or both of the first and second jaw members is movable relative to the other jaw member from a clamping position to an open position. A resilient member operably couples to the first and second jaw members. The resilient member is configured to bias the first and second jaw members in the clamping position and provide a closure force on tissue disposed therebetween.Type: GrantFiled: June 10, 2019Date of Patent: August 31, 2021Assignee: Covidien LPInventors: David M. Garrison, Jeffrey M. Roy, Duane E. Kerr

Publication number: 20210259763Abstract: 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: ApplicationFiled: May 11, 2021Publication date: August 26, 2021Inventors: 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
