Vessel sealing cutting assemblies

摘要

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.
