Abstract:
1. An endoscopic forceps, comprising: a housing having a shaft that extends therefrom and defines a longitudinal axis therethrough; a handle assembly including a movable handle movable relative to the housing, the movable handle including at least one mechanical interface disposed thereon; an end effector assembly operatively connected to a distal end of the shaft and including a pair of first and second jaw members, at least one of the first and second jaw members movable relative to the other jaw member from an open position, wherein the first and second jaw members are disposed in spaced relation relative to one another, to a clamping position, wherein the first and second jaw members cooperate to grasp tissue therebetween; a drive assembly including a having a bias operably associated therewith; and a lock assembly operably coupled to the housing about a pivot point disposed within the housing and in operative communication with the movable handle via the at least one mechanical interface disposed thereon, wherein the at least one mechanical interface moves along a top peripheral surface of the lock assembly within the housing when the movable handle is moved proximally causing the lock assembly to rotate about the pivot point for positioning a distal end of the lock assembly into engagement with at least a portion of the drive assembly such that the bias of the resilient member retains the first and second jaw members in the clamping position.
