Patent number: 10201384Abstract: 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: October 24, 2017Date of Patent: February 12, 2019Assignee: 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

Publication number: 20180250064Abstract: A bipolar electrosurgical instrument is provided. The bipolar electrosurgical instrument includes first and second shafts each having a jaw member extending from a distal end thereof and a handle disposed at a proximal end thereof for effecting movement of the jaw members relative to one another. A first conductive lead is adapted to connect to a first electrical potential and a second conductive lead is adapted to connect to a second electrical potential. One of the first and second conductive leads extends through the pivot to connect to a respective jaw member.Type: ApplicationFiled: May 3, 2018Publication date: September 6, 2018Inventors: JEFFREY M.

Publication number: 20180206908Abstract: 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: March 21, 2018Publication date: July 26, 2018Inventors: JOHN R. TWOMEY, DYLAN R. KINGSLEY, JAMES D. ALLEN, IV, SEAN T. O'NEILL, JEFFREY M. ROY

Patent number: 9375245Abstract: An end effector of a forceps includes first and second jaw members movable between spaced-apart and approximated positions for grasping tissue. Each jaw member includes a tissue sealing plate that is selectively energizable. The tissue sealing plates are configured to conduct energy therebetween and though tissue to seal tissue. A knife includes a distal surface and an upper surface. The knife is selectively translatable between a retracted position and an extended position wherein the knife extends between the jaw members. The distal surface is configured for dynamic tissue cutting upon translation of the knife from the retracted to the extended position. The upper surface is configured for static tissue cutting with the knife in the extended position. The knife is selectively energizable and is configured to conduct energy between the knife and one or both of the tissue sealing plates and through tissue to electrically cut tissue.Type: GrantFiled: October 22, 2015Date of Patent: June 28, 2016Assignee: Covidien LPInventors: Jeffrey M.
