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 a section of tissue, comprising:
- a first jaw having a longitudinal axis;
a second jaw disposed in parallel and opposed correspondence with the first jaw;
a first rotatable shaft rotatable about a longitudinal axis, the first rotatable shaft coupled to the first jaw and adapted to cause the first jaw to travel linearly in a direction perpendicular to the longitudinal axes while maintaining the parallel correspondence between the first and second jaws; and
a wedge pushing mechanism including a wedge and a wedge guide, the wedge having a sloped top surface, a horizontal threaded bore coaxial with the first rotatable shaft, and an upwardly extending blade member configured to cut tissue as the wedge moves through the wedge guide, the blade member supported directly on top of the wedge, wherein the sloped top surface is disposed between the longitudinal axis and a tissue contacting surface.

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.

16. A fastening and cutting attachment for use with an electromechanical driver device for cutting and fastening a section of tissue, comprising:
-
a first jaw having a longitudinal axis; a second jaw disposed in parallel and opposed correspondence with the first jaw; a first driver coupled to the first jaw, the first driver being actionably coupleable to the electromechanical driver device, the first driver including a first horizontal rotatable shaft that drives at least one threaded turning shaft and is adapted to cause the first jaw to linearly travel along an axis perpendicular to the axis of parallel correspondence of the first and second jaws, the first horizontal rotatable shaft being rotatable about a longitudinal axis, the first jaw separating from the second jaw when the first horizontal rotatable shaft is rotated in a first direction to open the jaws, the first jaw closing toward the second jaw when the first horizontal rotatable shaft is rotated in a second direction opposite to the first direction to close the jaws; and a wedge pushing mechanism including a wedge and a wedge guide, the wedge having a sloped top surface, a horizontal threaded bore coaxial with the first rotatable shaft, and an upwardly extending blade member configured to cut tissue as the wedge moves through the wedge guide, the blade member supported directly on top of the wedge, wherein the sloped top surface is disposed between the longitudinal axis and a tissue contacting surface. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
