End Effector Assembly for Electrosurgical Device
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 disposed therein, the 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, each of the first and second jaw members being pivotable about a living hinge, each of the jaw members including a cam slot defined at a proximal end thereof;
wherein at least one of the jaw members is operatively connected to a distal end of the actuation tube via a cam pin such that distal reciprocation of the actuation tube cams each of the jaw members towards one another about the living hinge.

Abstract
A bipolar forceps is provided and includes a housing having a shaft that extends therefrom which defines a longitudinal axis therethrough. The housing including a drive assembly disposed therein and is operable to reciprocate an actuation tube within the shaft. The bipolar forceps includes an end effector assembly operatively connected to a distal end of the shaft and has a pair of first and second jaw members. The first and second jaw members are pivotable about a living hinge and are adapted to connect to an electrosurgical energy source. Each of the jaw members includes a cam slot defined at a proximal end thereof. One or more of the jaw members is operatively connected to a distal end the actuation tube via a cam pin such that distal reciprocation of the actuation tube cams each of the jaw members towards one another about the respective living hinge to grasp tissue.

10. A bipolar forceps, comprising:
-
a housing having a shaft that extends therefrom that defines a longitudinal axis therethrough, the shaft including cam pins located at a distal end thereof and at least one groove, the housing including a drive assembly disposed therein operable to reciprocate an actuation rod 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, each of the first and second jaw members being pivotable about a living hinge, each of the jaw members including a cam slot defined at a proximal end thereof and at least one support member operatively connected to the at least one groove; wherein at least one of the jaw members is operatively connected to a distal end the actuation rod such that distal reciprocation of the actuation rod cams each of the jaw members towards one another about the living hinge. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A method for performing an electrosurgical procedure, the method comprising the steps of:
-
providing a bipolar forceps including; a housing having a shaft that extends therefrom, the housing including a drive assembly disposed therein operable to reciprocate an actuation tube within the shaft to actuate a pair of first and second jaw members about a living hinge, each of the jaw members including a cam slot defined at a proximal end thereof at least one of the jaw members operatively connected to a distal end the actuation tube via a cam pin; positioning tissue between the pair of first and second jaw members; 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.
