Abstract
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 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.
Claims15
An endoscopic forceps, comprising:
- an end effector assembly including a pair of first and second jaw members, 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;
- at least one of the first and second jaw members including at least one cam slot defined therein configured to receive a cam member that upon movement thereof rotates the first and second jaw members from the clamping position to the open position;
- and
- a resilient member operably coupled to at least one of the first and second jaw members via a spring pin positioned through the first and second jaw members, the resilient member configured to bias the first and second jaw members in the clamping position and provide a closure force on tissue disposed therebetween.
A method for performing a laparoscopic surgical procedure, the method comprising:
- providing an endoscopic instrument comprising:
- an end effector assembly including a pair of first and second jaw members, at least one of the first and second jaw members movable relative to the other from a clamping position to an open position, the at least one movable jaw including at least one cam slot defined therein configured to receive a cam member;
- and
- a resilient member coupled to at least one of the first and second jaw members via a spring pin positioned through the first and second jaw members, the resilient member configured to bias the first and second jaw members in the clamping position and provide a closure force on tissue disposed therebetween;
- biasing the first and second jaw members in the clamping position with the resilient member for positioning the end effector adjacent to tissue;
- moving the movable jaw member to the open position;
- positioning tissue between the first and second jaw members;
- and
- moving the movable jaw member to the clamping position.
