Patent number: 11253280Abstract: A forceps includes an end effector assembly having first and second jaw members disposed in parallel orientation relative to one another. One or both of the jaw members is movable along a first axis relative to the other jaw member between a spaced-apart position and an approximated position for grasping tissue therebetween. The first and second jaw members are configured to maintain the parallel orientation therebetween upon movement of the jaw members between the spaced-apart and approximated positions. A drive bar is coupled to one or both of the jaw members. The drive bar is selectively movable along a second axis that is different from the first axis between first and second positions for moving the jaw members between the spaced-apart and approximated positions.Type: GrantFiled: September 19, 2019Date of Patent: February 22, 2022Assignee: Covidien LPInventor: Stephen M. Kendrick

Patent number: 11172952Abstract: A surgical apparatus includes a housing that supports a shaft assembly. The shaft assembly defines a longitudinal axis therethrough and includes coaxially aligned outer and inner shaft members. The inner shaft member is movable within the outer shaft member. An end effector includes a pair of jaw members disposed at a distal end of the outer shaft. At least one of the jaw members is pivotably coupled to the outer shaft and is movable between open and clamping configurations for grasping tissue. The inner shaft contacts a proximal end of the moveable jaw member to maintain the movable jaw member in the open configuration and is slidable against the movable jaw member to move the moveable jaw member between the open configuration and clamping configuration.Type: GrantFiled: November 14, 2016Date of Patent: November 16, 2021Assignee: Covidien LPInventor: Stephen M.

Patent number: 9743976Abstract: A forceps includes a housing defining a window and having an outer shaft extending therefrom. An end effector assembly disposed at a distal end of the outer shaft includes first and second jaw members including distal portions and proximal portions and movable between spaced-apart and approximated positions. An inner shaft is slidably disposed within the outer shaft such that, when the jaw members are disposed in the spaced-apart position, the inner shaft is disposed in a distal position. When the jaw members are moved to the approximated position, the proximal portions urge the inner shaft to a proximal position. An indicator member coupled to the inner shaft includes first and second indicators. The first indicator is visible through the window when the inner shaft is disposed in the distal position. The second indicator is visible through the window when the inner shaft is disposed in the proximal position.Type: GrantFiled: June 27, 2016Date of Patent: August 29, 2017Assignee: COVIDIEN LPInventor: Stephen M.

Publication number: 20170007317Abstract: An electrosurgical pencil with integrated tweezers includes-an elongated housing having an open distal end and an actuator operatively associated therewith. First and second jaw members extend distally through the open distal end of the elongated housing and are transitionable between a closed position and an open position upon actuation of an actuator. One or both of the jaw members is configured to treat tissue with monopolar energy and both jaw members are configured to treat tissue with bipolar energy. One or more switches is operably coupled to a controller disposed in the housing and configured to activate the first and second jaw members to treat tissue with monopolar and bipolar energy.Type: ApplicationFiled: September 26, 2016Publication date: January 12, 2017Inventors: JAMES D.
