Surgical instrument with resilient driving member and related methods of use

摘要

A forceps is provided and includes a housing having a shaft. An end effector assembly operatively connects to a distal end of the shaft and includes a pair of first and second jaw members. One or both of the first and second jaw members is movable relative to the other jaw member from a clamping position to an open position. A resilient member operably couples to at least one of the first and second jaw members. The resilient member is configured to bias the first and second jaw members in the clamping position and provide a closure force on tissue disposed therebetween.

1. An endoscopic forceps, comprising:
a shaft having a proximal end and a distal end and defining a longitudinal axis; an end effector assembly disposed at the distal end of the shaft and including a first jaw member and a second jaw member, at least one of the first and second jaw members movable relative to the other between a clamping position wherein the first and second jaw members cooperate to grasp tissue therebetween and an open position wherein the first and second jaw members are disposed in spaced relation relative to one another; a first cam follower disposed on a proximal end of the first jaw member and a second cam follower disposed on a proximal end of the second jaw member; a cam assembly disposed within the shaft and configured to translate along the longitudinal axis, the cam assembly including a cam pin disposed thereon, the cam pin configured to slide along the first cam follower and the second cam follower; a drive rod configured to translate along the longitudinal axis defined by the shaft; and a resilient member disposed within a guide and operatively coupling the drive rod to the cam assembly.
