Expanding parallel jaw device for use with an electromechanical driver device
First Claim
1. A fastening and cutting attachment for use with an electromechanical driver device for cutting and fastening tissue, comprising:
- a first jaw defining a longitudinal axis;
a second jaw disposed in parallel and opposed correspondence with the first jaw;
a first motor configured to actuate a first flexible drive shaft coupled to the first jaw, the first flexible drive shaft adapted to engage a horizontal gear shaft for displacing a vertical shaft connecting the first and second jaws; and
a second motor configured to actuate a second flexible drive shaft coupled to the second jaw, the second flexible drive shaft coupled to a horizontal driver for enabling cutting and stapling of a section of tissue disposed between the first and second jaws;
wherein the horizontal gear shaft and the horizontal driver are parallel to one another at a fixed distance to one another, such that the first jaw moves in a direction transverse to a longitudinal axis of the horizontal gear shaft.

Abstract
A cutting and stapling device for use as an attachment to an electromechanical device driver comprises an upper jaw and a lower jaw which separate and close against one another in a continuously parallel alignment. The upper jaw includes a series of staple guides corresponding to one or more staples in a removable staple tray disposed within a lower jaw, whereby a blade and wedge having a threaded bore travel upon a matching threaded shaft in a channel disposed in the lower jaw below the staple tray, such that rotation of the threaded shaft causes movement of the wedge through the channel while a sloped surface of the wedge contacts the staples to push the staples against the staples guides, closing the staples.
