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:
an elongated shaft having a proximal end and a distal end; 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 from a clamping position wherein the first and second jaw members cooperate to grasp tissue therebetween to an open position wherein the first and second jaw members are disposed in spaced relation relative to one another; a cam member configured to translate along a longitudinal axis defined through the shaft; a drive rod configured to translate along the longitudinal axis of the shaft; and a resilient member disposed proximate to at least one of the jaw members and configured to operably couple a distal end of the of the drive rod to a proximal end of the cam member, wherein at least one of the first and second jaw members includes at least one cam slot defined therein configured to receive the cam member such that longitudinal movement of the resilient member along the longitudinal axis of the shaft moves the first and second jaw members from the clamping position to the open position.
