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.

Claims

1. A method for operating a surgical device, the method comprising:

providing a surgical device comprising a jaw and a surgical member, the surgical device further including a first rotatable drive shaft, a second rotatable drive shaft, a first driver, and a second driver;

selecting, via the first rotatable drive shaft, one of the first driver and the second driver, the first driver for performing a first movement function of the surgical device and the second driver for performing a second movement function of the surgical device;

engaging the selected one of the first and second drivers with the second rotatable drive shaft;

driving, via the second rotatable drive shaft, the selected one of the first and second drivers;

actuating the second rotatable drive shaft; and

moving, via the second rotatable drive shaft, the surgical member within the jaw.

2. The method of claim 1, further comprising performing a third movement function of the surgical device, via a third driver, wherein the engaging step includes engaging a selected one of the first, second and third drivers with the second rotatable drive shaft;

and the driving step includes driving, via the second rotatable drive shaft, the selected one of the first, second and third drivers.

3. The method of claim 2, further comprising performing a fourth movement function of the surgical device, via a fourth driver, wherein the engaging step includes engaging a selected one of the first, second, third and fourth drivers with the second rotatable drive shaft;

and wherein the driving step includes driving, via the second rotatable drive shaft, the selected one of the first, second, third and fourth drivers.

4. The method of claim 1, further comprising:

coupling a shaft portion of the surgical device to a handle, the handle defining a longitudinal axis;

actuating the second rotatable drive shaft; and

rotating, via the second rotatable drive shaft, the shaft portion of the surgical device relative to, and about the longitudinal axis of, the handle.

5. The method of claim 1 further comprising:

coupling the jaw to a shaft portion of the surgical device;

actuating the second rotatable drive shaft; and

moving, via the second rotatable drive shaft, the jaw relative to the shaft portion.

6. The method of claim 1, further comprising:

coupling the jaw to a second jaw;

actuating the second rotatable drive shaft; and

moving, via the second rotatable drive shaft, the first jaw relative to the second jaw.

7. The method of claim 1, further comprising controlling the operation of the surgical device via a control system.

8. The method of claim 7, wherein the controlling step includes operating the surgical device via signals received by the control system via at least one control device mounted on the surgical device.

9. A method for operating a surgical device, the method comprising:

providing a surgical device comprising a jaw and a surgical member, the surgical device further including a first rotatable drive shaft, a second rotatable drive shaft, a first driver, a second driver, and a third driver;

selecting, via the first rotatable drive shaft, one of the first driver, the second driver, or the third driver, the first driver performing a first movement function of the surgical device, the second driver performing a second movement function of the surgical device, and the third driver performing a third movement function of the surgical device;

engaging the selected one of the first, second, or third drivers with the second rotatable drive shaft; and

driving, via the second rotatable drive shaft, the selected one of the first, second, or third drivers.

10. The method of claim 9, further comprising performing a fourth movement function of the surgical device, via a fourth driver;

wherein the engaging step includes engaging a selected one of the first, second, third or fourth drivers with the second rotatable drive shaft; and

wherein the driving step includes driving, via the second rotatable drive shaft, the selected one of the first, second, third or fourth drivers.

11. The method of claim 9, further comprising:

coupling a shaft portion of the surgical device to a handle, the handle defining a longitudinal axis;

actuating the second rotatable drive shaft; and

rotating, via the second rotatable drive shaft, the shaft portion of the surgical device relative to, and about the longitudinal axis of, the handle.

12. The method of claim 9, further comprising:

coupling the jaw to a shaft portion;

actuating the second rotatable drive shaft; and

moving, via the second rotatable drive shaft, the jaw relative to the shaft portion.

13. The method of claim 9, further comprising:

coupling the jaw to a second jaw;

actuating the second rotatable drive shaft; and

moving, via the second rotatable drive shaft, the first jaw relative to the second jaw.

14. The method of claim 9, further comprising controlling the operation of the surgical device via a control system.

15. The method of claim 14, wherein the controlling the operation of the surgical device includes operating the surgical device via signals received by the control system via at least one control device mounted on the surgical device.

16. A method for operating a surgical device, the method comprising:

providing a surgical device with a shaft portion coupled to a handle, the handle defining a longitudinal axis, the surgical device further including a first rotatable drive shaft, a second rotatable drive shaft, a first driver, and a second driver;

selecting, via the first rotatable drive shaft, one of the first driver or the second driver, the first driver performing a first movement function of the surgical device and the second driver performing a second movement function of the surgical device;

engaging the selected one of the first or second drivers with the second rotatable drive shaft;

driving, via the second rotatable drive shaft, the selected one of the first or second drivers;

actuating the second rotatable drive shaft; and

rotating, via the second rotatable drive shaft, the shaft portion of the surgical device relative to, and about the longitudinal axis of, the handle of the surgical device.

17. The method of claim 16, further comprising performing a third and fourth movement function, via third and fourth drivers, respectively, of the surgical device;

wherein the engaging step includes engaging a selected one of the first, second, third or fourth drivers with the second rotatable drive shaft; and

wherein the driving step includes driving, via the second rotatable drive shaft, the selected one of the first, second, third or fourth drivers.

18. The method of claim 16, further comprising:

coupling a jaw to a shaft portion;

actuating the second rotatable drive shaft; and

moving, via the second rotatable drive shaft, the jaw relative to the shaft portion.

19. The method of claim 16, further comprising:

coupling a first jaw to a second jaw to the surgical device;

actuating the second rotatable drive shaft; and

moving, via the second rotatable drive shaft, the first jaw relative to the second jaw.

20. The method of claim 16, further comprising controlling the operation of the surgical device via a control system by operating the surgical device via signals received by the control system via at least one control device mounted on the surgical device.
