Surgical device
First Claim
1. A surgical device, comprising:
- a first jaw;
a second jaw disposed in opposed correspondence with the first jaw, the second jaw mechanically coupled to the first jaw at a proximal end opposite a distal end;
a cutting element disposed within and rotatable relative to the second jaw and having an actuating member receiving face; and
a first driver configured to move the cutting element proximally from an initial position at the distal end of the second jaw toward the proximal end of the second jaw to cut a section of tissue disposed between the first and second jaws,a fixed actuating member fixed relative to the second jaw and adjacent to the actuating member receiving face of the cutting element, such that the actuating member receiving face engages the fixed actuating member during proximal movement of the cutting element, so as to cause the cutting element to rotate about a central pivot,wherein the cutting element is in a retracted position in the initial position with a cutting edge of the cutting element unexposed to prevent cutting of the section of tissue, and is rotatable to an unretracted position with the cutting edge of the cutting element exposed to cut the section of tissue.

Abstract
A surgical device includes a first jaw and a second jaw disposed in opposed correspondence with the first jaw. The second jaw is mechanically coupled to the first jaw at a proximal end opposite a distal end. A cutting element is disposed within the second jaw, and a first driver is configured to move the cutting element proximally from the distal end toward the proximal end of the second jaw to cut a section of tissue disposed between the first and second jaws. The device may also include a stapling element disposed within the second jaw. The cutting element and the stapling element may be contiguous so as to define a cutting and stapling element, such as a wedge having a blade disposed thereon. As the wedge is moved proximally from the distal end of the second jaw to the proximal end, the wedge pushes a plurality of staples against a plurality of opposing staple guides disposed in the first jaw in order to staple a section of tissue while cutting the section of tissue.

30. An electro-mechanical surgical system, comprising:
-
an elongated shaft; at least a first axially rotatable drive shaft disposed within the elongated shaft; a surgical device configured to detachably couple to a distal end of the elongated shaft, wherein and rotatable relative to the device includes; a first jaw; a second jaw disposed in opposed correspondence with the first jaw, the second jaw mechanically coupled to the first jaw at a proximal end opposite a distal end; a cutting element disposed within the second jaw and having an actuating member receiving face; a first driver configured to move the cutting element proximally from an initial position at the distal end of the second jaw toward the proximal end of the second jaw to cut a section of tissue disposed between the first and second jaws; and a fixed actuating member fixed relative to the second jaw and adjacent the actuating member receiving face of the cutting element, such that the actuating member receiving face engages the fixed actuating member during proximal movement of the cutting element, so as to cause the cutting element to rotate about a central pivot, wherein the cutting element is in a retracted position in the initial position with a cutting edge of the cutting element unexposed to prevent cutting of the section of tissue, and is rotatable to an unretracted position with the cutting edge of the cutting element exposed to cut the section of tissue; and a motor system configured to drive the at least a first drive shaft. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53)
