The surgical instrument includes a handle portion, a tubular body portion extending from the handle portion and defining a longitudinal axis, and tool structure associated with a distal portion of the tubular body portion. A rotation assembly is provided for effectuating rotation of the tool structure about the longitudinal axis of the body portion. Rotation locking structure is provided to lock the rotation assembly at a predetermined orientation such that it cannot be rotated with respect to the handle.

[ What is claimed is:] [1.] A surgical apparatus comprising:a handle portion;a body portion extending from said handle portion and defining a longitudinal axis;tool means operatively associated with a distal portion of the body portion and remotely actuatable from said handle portion for manipulation of tissue;rotation means operatively associated with said tool means for effecting remote rotation of the tool means about a longitudinal axis of the body portion relative to the handle portion; androtation locking means for locking the rotation means at a fixed position such that the rotation means cannot be rotated with respect to the handle portion;wherein said rotation locking means comprises ratchet structure coaxial with a rotatable collar, the ratchet structure mounted for reciprocal longitudinal movement between an engaged position in restrictive engagement with the rotatable collar and a disengaged position out of engagement with said rotatable collar.
