Patent number: 10085794Abstract: The present disclosure provides a bipolar forceps. The bipolar forceps includes a housing having a handle assembly including a movable handle and one or more shafts. An end effector assembly operatively connects to a distal end of the shaft and includes a pair of first and second jaw members. A solenoid is in operative communication with the movable handle and operatively couples to a drive rod operatively coupled to at least one of the first and second jaw members for causing movement thereof. One or both of the first and second jaw members includes one or more teeth configured to engage one or more teeth located on the drive rod such that rotation of the solenoid imparts one of longitudinal and rotational movement of the drive rod such that at least one of the first and second jaw members moves between the open and closed positions.Type: GrantFiled: May 16, 2016Date of Patent: October 2, 2018Assignee: COVIDIEN LPInventors: Duane E. Kerr, Peter D. Gadsby, Glenn A. Horner

Patent number: 9888958Abstract: A forceps includes an end effector assembly including first and second jaw members. 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 jaw frame including an engagement recess defined on each lateral side thereof and a replaceable component configured for slidable positioning about the jaw frame. The replaceable component includes an outer jaw housing having an engagement tang disposed on each lateral side thereof. The engagement tangs are configured to engage the engagement recesses of the jaw frame upon slidable positioning of the replaceable component about the jaw frame to secure the replaceable component to the jaw frame. The replaceable component includes an electrically conductive tissue sealing plate engaged to the outer jaw housing to define a tissue sealing surface.Type: GrantFiled: January 23, 2015Date of Patent: February 13, 2018Assignee: COVIDIEN LPInventors: Allan J.

Patent number: 8968307Abstract: A forceps includes an end effector assembly having first and second jaw members. One (or both) of the first and second 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 longitudinally-extending blade channel defined therein. An electrical cutting insert is releasably engageable within the blade channel of the jaw member such that the jaw member is transitionable between a mechanical cutting mode, wherein the electrical cutting insert is disengaged from the jaw member to permit reciprocation of a knife blade through the blade channel for mechanically cutting tissue grasped between the jaw members, and an electrical cutting mode, wherein the electrical cutting insert is engaged within the blade channel of the jaw member for electrically cutting tissue grasped between the jaw members.Type: GrantFiled: August 18, 2011Date of Patent: March 3, 2015Assignee: Covidien LPInventors: Allan J.
