Apparatus for Performing an Electrosurgical Procedure
First Claim
1. A forceps, comprising:
- a housing having a shaft that extends therefrom that defines a longitudinal axis therethrough;
an end effector assembly operatively connected to a distal end of the shaft and having a pair of first and second jaw members, the first and second jaw members moveable from an open position wherein the jaw members are disposed in spaced relation relative to one another, to a clamping position wherein the jaw members cooperate to grasp tissue therebetween;
a handle assembly including a movable handle movable relative to a fixed handle operable connected to impart movement of the jaw members relative to each other; and
a rotating assembly for rotating the shaft and the end effector assembly about the longitudinal axis, the rotating assembly supported in the housing and including a first drive wheel defining an axis of rotation substantially perpendicular to the longitudinal axis of the shaft and a second drive wheel defining an axis of rotation substantially parallel to the longitudinal axis of shaft,wherein each of the first and second drive wheels are selectively movable relative to the housing and configured such that rotation of the first drive wheel causes rotation of the second drive wheel and the shaft.

Abstract
A surgical instrument is provided. The surgical instrument includes a housing having a shaft that extends therefrom that defines a longitudinal axis therethrough. An end effector assembly is operatively connected to a distal end of the shaft and includes a pair of first and second jaw members. The surgical instrument includes a handle assembly that includes a movable handle movable relative to a fixed handle operable to impart movement of the jaw members relative to one another. A rotating assembly is configured for rotating one of the shaft and end effector assembly about the longitudinal axis. The rotating assembly is supported in the housing and includes first and second drive. Each of the first and second drive wheels are selectively movable relative to the housing and configured such that rotation of the first drive wheel causes rotation of the second drive wheel and the shaft.

19. A surgical instrument configured to manipulate tissue, the surgical instrument comprising:
-
a housing having a shaft that extends therefrom that defines a longitudinal axis therethrough; an end effector assembly operatively connected to a distal end of the shaft and having a pair of first and second jaw members, the first and second jaw members moveable from an open position wherein the jaw members are disposed in spaced relation relative to one another, to a clamping position wherein the jaw members cooperate to grasp tissue therebetween; a handle assembly including a movable handle movable relative to a fixed handle operable to impart movement of the jaw members relative to one another; and a rotating assembly for rotating the shaft and the end effector assembly about the longitudinal axis, the rotating assembly being supported in the housing and including a first drive wheel defining an axis of rotation substantially perpendicular to the longitudinal axis of the shaft and a second drive wheel defining an axis of rotation substantially parallel to the longitudinal axis of shaft, wherein each of the first and second drive wheels are selectively movable relative to the housing, wherein each of the first and second drive wheels includes a toothless surface and tooth bearing surface, the plurality of teeth associated with the first drive wheel configured to mesh with the plurality of teeth associated with the second drive wheel such that rotation of the first drive wheel causes rotation of the second drive wheel and the shaft.
