Abstract

A surgical device is provided that includes a jaw portion, having a first jaw in opposed correspondence with a second jaw, the second jaw including a surgical member. The surgical device may include a shaft portion coupled to a proximal end of the jaw portion and at least one motor configured to rotate the jaw portion relative to the shaft portion, to move the jaw portion relative to the shaft portion, move the first jaw relative to the second jaw and move the surgical member within the second jaw. The surgical member may be prevented from moving within the second jaw unless the first jaw is in a closed position relative to the second jaw. Advantageously, the surgical member may include one or both a cutting element or a stapling element, disposed within one of the jaws.

Claims

1. A surgical device, comprising:

a first jaw;

a second jaw in opposed correspondence to the first jaw;

a shaft pivotably coupled to at least one of the first and second jaws, the shaft defining a longitudinal axis therethrough;

a first driver configured to be coupled to a first rotatable drive shaft;

a second driver configured to be coupled to a second rotatable drive shaft;

a first gear train having a first gear element arrangement;

a second gear train having a second gear element arrangement; and

a wedge member mechanically cooperating with a wedge driver, the wedge member having a blade rotatably coupled thereon, such that the blade rotates between a first and a second position, wherein the wedge driver is actuated by one of the first gear train and the second gear train.

2. The surgical device according to claim 1, wherein the wedge member is slidably supported within the second jaw and the wedge driver is rotatably supported within the second jaw.

3. The surgical device according to claim 1, wherein the wedge driver is configured to retract the wedge member from a distal end to a proximal end of a staple tray supported within the second jaw.

4. The surgical device according to claim 3, wherein at the distal end of the staple tray a contact face of the blade engages a lip of a first housing in an initial advancement stage.

5. The surgical device according to claim 4, wherein the lip of the first housing is configured to actuate initial rotation of the blade relative to the wedge member.

6. The surgical device according to claim 1, wherein, in the first position, a cutting edge of the blade is substantially parallel to the wedge driver.

7. The surgical device according to claim 1, wherein, in the second position, a cutting face of the blade is substantially perpendicular to the wedge driver.

8. The surgical device according to claim 3, wherein at the proximal end of the staple tray a contact face of the blade is enclosed within a second housing in a final advancement stage.

9. The surgical device according to claim 3, wherein staples are fired simultaneously with advancement of the blade from the distal end to the proximal end of the staple tray.

10. The surgical device according to claim 1, wherein the wedge member and blade move in unison across a length of the second jaw to cut a section of tissue disposed between the first and second jaws.

11. A surgical device, comprising:

a first jaw;

a second jaw in opposed correspondence to the first jaw;

a shaft pivotably coupled to at least one of the first and second jaws, the shaft defining a longitudinal axis therethrough;

a gear arrangement interposed between the first and second jaw members and the shaft, the gear arrangement including a first gear train and a second gear train, the first and second gear trains meshingly engaging first and second rotatable drive shafts, respectively, such that the first and second gear trains facilitate rotation of the first and second jaws relative to the longitudinal axis defined by the shaft; and

a wedge member mechanically cooperating with a wedge driver, the wedge member having a blade rotatably coupled thereon, such that the blade rotates between a first and a second position, wherein the wedge driver is actuated by one of the first gear train and the second gear train.

12. The surgical device according to claim 11, wherein the wedge member is slidably supported within the second jaw and the wedge driver is rotatably supported within the second jaw.

13. The surgical device according to claim 11, wherein the wedge driver is configured to retract the wedge member from a distal end to a proximal end of a staple tray supported within the second jaw.

14. The surgical device according to claim 13, wherein at the distal end of the staple tray a contact face of the blade engages a lip of a first housing in an initial advancement stage.

15. The surgical device according to claim 14, wherein the lip of the first housing is configured to actuate initial rotation of the blade relative to the wedge member.

16. The surgical device according to claim 11, wherein, in the first position, a cutting edge of the blade is substantially parallel to the wedge driver.

17. The surgical device according to claim 11, wherein, in the second position, a cutting face of the blade is substantially perpendicular to the wedge driver.

18. The surgical device according to claim 13, wherein at the proximal end of the staple tray a contact face of the blade is enclosed within a second housing in a final advancement stage.

19. The surgical device according to claim 13, wherein staples are fired simultaneously with advancement of the blade from the distal end to the proximal end of the staple tray.

20. The surgical device according to claim 11, wherein the wedge member and blade move in unison across a length of the second jaw to cut a section of tissue disposed between the first and second jaws.
