Patent number: 9033981Abstract: An endoscopic bipolar forceps includes a housing and a shaft, the shaft having an end effector assembly which includes two jaw members for grasping tissue therebetween. Each jaw member is adapted to connect to an electrosurgical energy source, enabling them to effect a tissue seal to tissue held therebetween. A drive assembly is included within the housing for moving the jaw members. A movable handle is also included, and movement thereof actuates the drive assembly to move the jaw members relative to each other. A knife channel is included within the end effector configured to allow reciprocation of a knife blade within the knife channel. The knife blade includes a proximal edge adapted to engage a proximal edge of the end effector to impede translation of the knife blade when the jaw members are in an open configuration and the knife blade is retracted within the end effector assembly.Type: GrantFiled: June 8, 2012Date of Patent: May 19, 2015Assignee: Covidien LPInventors: Jessica E. Olson, Jeffrey R. Unger

Patent number: 8241282Abstract: An endoscopic bipolar forceps includes a housing having a shaft affixed thereto the shaft including jaw members at a distal end thereof. The shaft includes a longitudinal axis defined therethrough and the jaw members are adapted to connect to a source of electrosurgical energy such that the jaw members are capable of conducting energy through tissue held therebetween to effect a tissue seal. A movable handle is included that is rotatable about a pivot to force a drive assembly to move the jaw members between the first and second positions. The pivot is located a fixed distance above the longitudinal axis. A cutting assembly is included having at least one blade element disposed within one of the jaw members. The blade element is selectively moveable from a first recessed position within the jaw member to a second extended position for cutting tissue. The cutting assembly also includes a remote actuator which reciprocates a camming element to move the blade element between the first and second positions.Type: GrantFiled: September 5, 2008Date of Patent: August 14, 2012Assignee: TYCO Healthcare Group LPInventors: Jeffrey R. Unger, David W. Hixson, Robert M. Sharp, James D. Allen, IV, Jessica E. Olson
