Abstract:
1. An endoscopic forceps, comprising: a housing having a shaft that extends therefrom and defines a longitudinal axis therethrough; an end effector assembly operatively connected to a distal end of the shaft and including first and second jaw members pivotably coupled to one another about a pivot, at least one of the first and second jaw members movable relative to the other 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 mechanism including a driving structure; a link assembly including at least two links and a central cam pin, the at least two links operably coupled to each other and the driving structure via the central cam pin, the at least two links operably coupled to respective ones of the first and second jaw members; a movable cam member disposed adjacent the end effector, the driving structure configured to move the movable cam member to cam the at least two links toward both a horizontal position and each other; and a first resilient member including a proximal end and a distal end, the proximal end of the first resilient member coupled to the central cam pin and the distal end of the first resilient member coupled to the movable cam member.
