Apparatus for Performing an Electrosurgical Procedure
First Claim
1. An endoscopic forceps, comprising:
- a housing having a shaft extending therefrom, the shaft defining a longitudinal axis therethrough;
an end effector assembly operably coupled to a distal end of the shaft for treating tissue and including first and second jaw members;
a rotating assembly operably coupled to the shaft and configured to rotate the shaft and the end effector about the longitudinal axis; and
a drive assembly configured to selectively and releasably engage the rotating assembly, wherein engagement of the rotating assembly with the drive assembly couples the rotating assembly to the shaft such that the shaft is rotatable about the longitudinal axis when the rotating assembly is rotated, and disengagement of the rotating assembly from the drive assembly uncouples the rotating assembly from the shaft such that the shaft is non-rotatable about the longitudinal axis when the rotating assembly is rotated.

Abstract
An endoscopic forceps includes a housing having a shaft extending therefrom for treating tissue. A longitudinal axis is defined through the shaft. An end effector assembly is operably coupled to a distal end of the shaft and includes a pair of first and second jaw members. A rotating assembly operably coupled to the shaft is configured to rotate the shaft and the end effector about the longitudinal axis. A drive assembly is configured to selectively and releasably engage the rotating assembly. Engagement of the rotating assembly with the drive assembly couples the rotating assembly to the shaft such that the shaft is rotatable about the longitudinal axis in a predetermined direction when the rotating assembly is rotated. And, disengagement of the rotating assembly from the drive assembly uncouples the rotating assembly from the shaft such that the shaft is non-rotatable about the longitudinal axis when the rotating assembly is rotated.
