Surgical device
First Claim
1. A method for operating a surgical device, the surgical device including a first jaw having a distal end and a second jaw having a distal end, wherein the second jaw is disposed in opposed correspondence with the first jaw, and wherein the first jaw is pivotably coupled to the second jaw, the method comprising:
- opening the first jaw and the second jaw by a first driver disposed in the second jaw;
positioning a section of tissue between the first jaw and the second jaw;
biasing the distal end of the first jaw towards the distal end of the second jaw, via a biasing element;
closing the first jaw and the second jaw so as to clamp the section of tissue between the first jaw and the second jaw;
rotating a clamp shaft assembly via the first driver, wherein a first portion of the clamp shaft assembly extends into a gearbox and a second portion of the clamp shaft assembly defines a drive socket having a slot for receiving a drive clip engaging a first rotatable drive shaft; and
limiting a distance that a proximal end of the first jaw is separated from a proximal end of the second jaw via a stopping element,wherein, when the first and second jaws are closed, the first jaw is initially pivoted about the stopping element, subsequently the first jaw is pivoted about a point at which the distal end of the first jaw contacts the distal end of the second jaw, such that thereafter the distal end of the first jaw is biased apart from the distal end of the second jaw, via the biasing element.

Abstract
A surgical device including a first jaw and a second jaw is presented. The surgical device also includes a biasing element that biases the distal end of the first jaw towards the distal end of the second jaw. The device also includes a first driver disposed in the second jaw and coupled to the first jaw. The first driver is configured to cause separation of the first jaw and the second jaw. The device further includes at least one of a cutting element and a stapling element disposed within the second jaw, preferably a blade rotatably mounted on a wedge. A second driver is configured to move the cutting element and/or the stapling element proximally from a distal end toward the proximal end of the second jaw to at least one of cut and staple a section of tissue disposed between the first and second jaws.
