Abstract

A surgical device is provided, the surgical device including a first driver for performing a first movement function; a second driver for performing a second movement function; a first rotatable drive shaft configured, upon actuation, to cause selective engagement of one of the first and second drivers with a second rotatable drive shaft, wherein the second rotatable drive shaft is configured to drive the selectively engaged one of the first and second drivers. Third and fourth drivers may also be included. The drivers may function to rotate a shaft portion of the surgical device relative to, and about the longitudinal axis of, a handle; move a jaw portion relative to the shaft portion; move a first jaw relative to a second jaw; and/or move a surgical member within the second jaw.

Claims

1-37. -37. (canceled)

38. A surgical device comprising:

a jaw portion, having a first jaw in opposed correspondence with a second jaw, the second jaw including a surgical member;

a shaft portion coupled to a proximal end of the jaw portion;

a handle defining a longitudinal axis;

at least one motor configured to rotate the shaft portion of the surgical device relative to the handle, move the jaw portion relative to the shaft portion, move the first jaw relative to the second jaw and move the surgical member within the second jaw.

39. The surgical device of claim 38, wherein the at least one motor is mounted in the handle.

40. The surgical device of claim 38, further comprising:

a remote housing, wherein the at least one motor is mounted in the remote housing.

41. The surgical device of claim 40, further comprising:

a flexible shaft for coupling the surgical device to the at least one motor in the remote housing.

42. The surgical device of claim 41, wherein the surgical device includes, in the handle, a first rotatable drive shaft and a second rotatable drive shaft,

and wherein the flexible shaft includes a first rotatable drive shaft coupleable to the first rotatable drive shaft in the handle and a second rotatable drive shaft coupleable to the second rotatable drive shaft in the handle.

43. The surgical device of claim 42, wherein the first rotatable drive shaft in the handle is configured to cause engagement of a selected driver with the second rotatable drive shaft.

44. The surgical device of claim 42, wherein the selected driver is configured, upon actuation of the driver via rotation of the second rotatable drive shaft in the handle and rotation of the second rotatable drive shaft in the flexible shaft via the at least one motor unit, to rotate the shaft portion of the surgical device relative to the handle, move the jaw portion relative to the shaft portion, move the first jaw relative to the second jaw and move the surgical member within the second jaw.
