Apparatus, System, and Method for Performing an Endoscopic Electrosurgical Procedure
First Claim
1. A bipolar forceps, comprising:
- a housing having a shaft that extends therefrom that defines a longitudinal axis therethrough, the housing including a drive assembly operable to reciprocate an actuation tube within the shaft; and
an end effector assembly operatively connected to a distal end of the shaft having a pair of first and second jaw members biased in an open configuration, at least one of the first and second jaw members pivotable about a living hinge from a first position wherein the jaw members are disposed in spaced relation relative to one another to a clamping position wherein the jaw members are moved closer to one another for grasping tissue, at least one of the jaw members including a cam slot defined at a proximal end thereof,wherein the at least one jaw member is operatively connected to a distal end of the actuation tube via a cam pin that operatively engages the cam slot such that proximal reciprocation of the actuation tube cams the at least one jaw member towards the other jaw member about the living hinge.

Abstract
A bipolar forceps is provided and includes a housing having a shaft that extends therefrom. The housing includes a drive assembly operable to reciprocate an actuation tube within the shaft. An end effector assembly operatively connects to a distal end of the shaft and includes a pair of first and second jaw members biased in an open configuration. One or both of the first and second jaw members is pivotable about a living hinge from a first position to a clamping position. One or both of the jaw members includes a cam slot defined at a proximal end thereof. One of the jaw members is operatively connected to a distal end of the actuation tube via a cam pin that operatively engages the cam slot such that proximal reciprocation of the actuation tube cams at least one jaw member towards the other jaw member about the living hinge

11. A method for performing an electrosurgical procedure, the method comprising the steps of:
-
providing a bipolar forceps including; a drive assembly operable to reciprocate an actuation tube; and an end effector assembly having a pair of first and second jaw members biased in an open configuration, at least one of the first and second jaw members pivotable about a living hinge from a first position wherein the jaw members are disposed in spaced relation relative to one another to a clamping position wherein the jaw members are moved closer to one another, at least one of the jaw members including a cam slot defined at a proximal end thereof, wherein the at least one jaw member is operatively connected to a distal end of the actuation tube via a cam pin that operatively engages the cam slot; positioning tissue between the pair of first and second jaw members; proximally actuating the drive assembly to move the actuation tube causing the cam pin to cam the first and second jaw members to pivot about the living hinge towards each other such that tissue is grasped therebetween; and applying electrosurgical energy to the jaw members such that a tissue seal may be effected therebetween.
