Surgical device having a rotatable jaw portion
First Claim
1. A surgical device, comprising:
- an elongate shaft assembly;
a drive system for applying a plurality of rotary control motions to the elongate shaft assembly;
a first gear train having a first gear element arrangement including a first pair of gear elements operably interfacing with a second gear element; and
a second gear train having a second gear element arrangement including a second pair of gear elements operably interfacing with a third gear element;
wherein at least one of the second or third gear elements defines a central axis coaxial with a pivot axis around which at least one of a first jaw or a second jaw pivots relative to the elongate shaft assembly, the first and second jaws positioned on a distal end of the elongate shaft assembly.

Abstract
A surgical device is provided that includes a jaw portion, having a first jaw in opposed correspondence with a second jaw, the second jaw including a surgical member. The surgical device may include a shaft portion coupled to a proximal end of the jaw portion and at least one motor configured to rotate the jaw portion relative to the shaft portion, to 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. The surgical member may be prevented from moving within the second jaw unless the first jaw is in a closed position relative to the second jaw. Advantageously, the surgical member may include one or both a cutting element or a stapling element, disposed within one of the jaws.

14. A surgical device, comprising:
-
an elongate shaft assembly; a first jaw, and a second jaw disposed in opposed correspondence relative to the first jaw, the first and second jaws attached at a distal end of the elongate shaft assembly; a drive system for applying a plurality of rotary control motions to the elongate shaft assembly, the drive system including a first driver coupled to a first rotatable drive shaft and a second driver coupled to a second rotatable drive shaft, wherein the first driver moves the first jaw relative to the second jaw, and the second driver drives a cutting and stapling element included in the second jaw; a first gear element arrangement including a first gear element, a second gear element, and a third gear element, where the first and second gear elements meshingly engage with the third gear element; and a second gear element arrangement including a fourth gear element, a fifth gear element, and a sixth gear element, where the fourth and fifth gear elements meshingly engage with the sixth gear element; wherein at least one of the first gear element arrangement or the second gear element arrangement is rotatably mounted about a pin. - View Dependent Claims (15, 16, 17, 18)
