Abstract

A surgical device is provided, the surgical device including a first driver for performing a first movement function; a second driver for performing a second movement function; a first rotatable drive shaft configured, upon actuation, to cause selective engagement of one of the first and second drivers with a second rotatable drive shaft, wherein the second rotatable drive shaft is configured to drive the selectively engaged one of the first and second drivers. Third and fourth drivers may also be included. The drivers may function to rotate a shaft portion of the surgical device relative to, and about the longitudinal axis of, a handle; move a jaw portion relative to the shaft portion; move a first jaw relative to a second jaw; and/or move a surgical member within the second jaw.

First claim

What is claimed is:

1. A surgical device comprising:
a jaw portion having a first jaw and a second jaw;
a shaft assembly coupled to a proximal end of the jaw portion, the shaft assembly defining a longitudinal axis;
a handle assembly supporting the jaw assembly; and
a drive assembly supported in the handle assembly, the drive assembly being configured to apply a plurality of control motions to the shaft assembly;
wherein the drive assembly includes a gear train operably communicating with a firing input bevel gear for actuating at least one gear of the gear train to transversely communicate with at least one other gear of the gear train; and
wherein the gear train includes a first bevel gear and a second bevel gear, the first and second bevel gears being coaxial with the longitudinal axis defined by the shaft assembly.

2. The surgical device according to claim 1 , wherein the gear train further includes a first articulation gear, a portion of the first articulation gear being disposed between the first and second bevel gears.

3. The surgical device according to claim 2 , wherein the first articulation gear is transverse to the first and second bevel gears.

4. The surgical device according to claim 3 , wherein the first articulation gear operably communicates with a second articulation gear, the first and second articulation gears disposed in a coaxial relationship.

5. The surgical device according to claim 1 , wherein the first and second bevel gears are idler gears.

6. The surgical device according to claim 1 , wherein the first and second bevel gears are transverse to the firing input bevel gear.

7. The surgical device according to claim 1 , wherein the first and second bevel gears are transverse to an articulation shaft disposed through the shaft assembly.

8. The surgical device according to claim 1 , wherein the gear train includes a bevel/spur gear component.

9. The surgical device according to claim 8 , wherein the bevel/spur gear component is transverse with at least one of the first or second bevel gears.

10. The surgical device according to claim 1 , wherein the first and second bevel gears define a pivot axis therethrough.

11. The surgical device according to claim 10 , wherein the pivot axis is perpendicular to the longitudinal axis defined by the shaft assembly.

12. A surgical device comprising:
a jaw portion;
a shaft assembly coupled to the jaw portion, the shaft assembly defining a longitudinal axis therethrough;
a handle assembly supporting the shaft assembly; and
a drive assembly supported in the handle assembly, the drive assembly mechanically cooperating with the shaft assembly, the drive assembly including a first gear arrangement transversely engaging a second gear arrangement;
wherein the first gear arrangement includes a first bevel gear and the second gear arrangement includes a second bevel gear, the first and second bevel gears being coaxial with the longitudinal axis defined by the shaft assembly.

13. The surgical device according to claim 12 , wherein the second gear arrangement operably communicates with a first articulation gear, a portion of the first articulation gear disposed between the first and second bevel gears.

14. The surgical device according to claim 13 , wherein the second gear arrangement operably communicates with a second articulation gear meshingly engaged with the first articulation gear, the first and second articulation gears disposed in a coaxial relationship.

15. The surgical device according to claim 12 , wherein the first and second bevel gears are idler gears.

16. The surgical device according to claim 12 , wherein the first and second bevel gears are transverse to a firing input bevel gear operably communicating with the drive assembly.

17. The surgical device according to claim 12 , wherein the first and second bevel gears are transverse to an articulation shaft disposed through the shaft assembly.

18. The surgical device according to claim 12 , further comprising a third gear arrangement, the third gear arrangement including at least a bevel/spur gear component.

19. The surgical device according to claim 18 , wherein the bevel/spur gear component is transverse with at least one of the first or second bevel gears of the first gear arrangement.
