Expanding parallel jaw device for use with an electromechanical driver device
View Patent ↗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.
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 arranged in parallel to the longitudinal axis of the first jaw, 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 tray of fasteners disposed in one of the first jaw and the second jaw.
2. The fastening and cutting attachment according to claim 1 , wherein the tray is selectively removable from the one of the first jaw and the second jaw.
3. The fastening and cutting attachment according to claim 1 , wherein the tray is selectively replaceable.
4. A fastening and cutting 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 arranged in parallel to the longitudinal axis of the first jaw, 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;
a cutter and stapler disposed within the second jaw and adapted to cut and fasten the section of tissue disposed between the first and second jaws when the first and second jaws are in a closed position;
a second rotatable shaft rotatable about a longitudinal axis arranged in parallel to the longitudinal axis of the first jaw and the longitudinal axis of the first rotatable shaft, the second rotatable shaft adapted to cause the cutter and stapler to travel linearly in a direction parallel to the longitudinal axes; and
a tray of fasteners disposed in one of the first jaw and the second jaw.
5. The fastening and cutting device according to claim 4 , wherein the tray is selectively removable from the one of the first jaw and the second jaw.
6. The fastening and cutting device according to claim 4 , wherein the tray is selectively replaceable.
7. A fastening and cutting device for cutting and fastening a section of tissue, comprising:
a first jaw;
a second jaw disposed in parallel and opposed correspondence with the first jaw;
a first driver coupled to the first jaw, the first driver including a first horizontal rotatable shaft adapted to cause the first jaw to linearly travel along an axis perpendicular to the parallel correspondence of the first and second jaws, the first horizontal rotatable shaft being rotatable about a longitudinal axis arranged in parallel to the parallel correspondence of the first and second jaws, 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;
a cutter and linear stapler device disposed in one of the first jaw and the second jaw, the cutter and linear stapler device coupled to a second driver, the cutter and linear stapler device being adapted to cut and staple a section of tissue disposed between the first and second jaws once the first jaw has been closed toward the second jaw, the cutter and linear stapler device including a tray of staples disposed in one of the first jaw and the second jaw.
8. The fastening and cutting device according to claim 7 , wherein the tray is selectively removable from the one of the first jaw and the second jaw.
9. The fastening and cutting device according to claim 7 , wherein the tray is selectively replaceable.
10. A fastening and cutting attachment for use with an electromechanical driver device for cutting and fastening a section of tissue, comprising:
a first jaw;
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 adapted to cause the first jaw to linearly travel along an axis perpendicular to the parallel correspondence of the first and second jaws, the first horizontal rotatable shaft being rotatable about a longitudinal axis arranged in parallel to the parallel correspondence of the first and second jaws, 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 tray of fasteners disposed in one of the first jaw and the second jaw.
11. The fastening and cutting device according to claim 10 , wherein the tray is selectively removable from the one of the first jaw and the second jaw.
12. The fastening and cutting device according to claim 10 , wherein the tray is selectively replaceable.
