摘要:
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.
