Surgical device
First Claim
1. A surgical device, comprising:
- a first jaw having a distal end;
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, wherein the first jaw is curved such that the distal end of the first jaw curves towards the distal end of the second jaw;
at least one of a cutting element and a stapling element disposed within the second jaw;
a driver configured to move at least one of the cutting element and 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;
a threaded rod coupled to a threaded bore disposed on the second jaw, the threaded rod coupled to the first jaw, the first jaw configured to at least partially straighten in response to a clamping force exerted between the first jaw and the second jaw by a relative rotation between the threaded rod and the threaded bore; and
a rotatable shaft extending generally longitudinally relative to the second jaw and being generally perpendicular to the threaded rod, the rotatable shaft configured to cause axial rotation of the threaded bore with respect to the second jaw.

Abstract
A surgical device that includes a first jaw having a distal end and a second jaw having a distal end. The second jaw is disposed in opposed correspondence with the first jaw. The first jaw is pivotably coupled to the second jaw. The surgical device also includes a biasing element, such as a spring, that biases the distal end of the first jaw towards the distal end of the second jaw. The device may also include 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 when the first driver is actuated for opening the jaws and to close the first jaw and the second jaw when the first driver is actuated for closing the jaws. The device may also include 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. By biasing the distal ends of the first and second jaws towards each other, the surgical device may prevent a section of tissue which is disposed between the first and second jaws from escaping out from between the distal ends of the first and second jaws.
