Abstract

A surgical device includes a housing and a hollow shaft extending from the housing. The hollow shaft includes one or more drive shafts disposed within the hollow shaft. Each drive shaft is detachably coupled to a surgical instrument and is operable to control moving parts on the surgical instrument. A method for performing a surgical procedure includes the steps of inserting a hollow shaft containing one or more drive shafts into the body via a first orifice; inserting a surgical instrument into the body via a second orifice, the surgical instrument being configured to couple with the hollow shaft to connect the surgical instrument with one or more drive shafts; and coupling the hollow shaft and the surgical instrument after the hollow shaft and surgical instrument are inserted into the body.

Claims

1. A method for performing a procedure on a body, comprising the steps of:

(a) providing a hollow shaft having a proximal end and a distal free end without any surgical instrument supported on the distal free end, the hollow shaft having a diameter and containing a drive shaft rotatably disposed therein, the distal free end of the hollow shaft configured to permit a surgical instrument to be mounted to the distal free end of the hollow shaft;

(b) inserting the distal free end of the hollow shaft without any surgical instrument attached thereto in the body via a first body orifice;

(c) inserting a surgical instrument into the body via a second body orifice, the surgical instrument including a coupling complimentary to and configured to couple with the distal free end of said hollow shaft to connect the drive shaft with the surgical instrument in operable communication; and

(d) coupling the hollow shaft and the surgical instrument via the coupling to mount the surgical instrument to the distal end of the hollow shaft after the steps of inserting the hollow shaft and inserting the surgical instrument.

2. The method according to claim 1, wherein the hollow shaft and the surgical instrument are coupled in the coupling step intracorporeally.

3. The method according to claim 1, comprising the step of performing a surgical procedure after the coupling step.

4. The method according to claim 3, wherein the surgical procedure includes a tissue stapling procedure.

5. The method according to claim 3, wherein the surgical procedure includes a tissue stapling and cutting procedure.

6. The method according to claim 3, wherein the surgical procedure includes an anastomosis procedure.

7. The method according to claim 1, wherein the surgical instrument includes at least one of a surgical stapler instrument, a surgical stapler and cutter instrument, and an anastomosis instrument.

8. The method according to claim 1, comprising the step of withdrawing the coupled hollow shaft and surgical instrument via the first orifice.

9. The method according to claim 1, wherein the first orifice includes at least one of a natural orifice, an incision and a cannula.

10. The method according to claim 1, wherein the second orifice includes at least one of a natural orifice, an incision and a cannula.

11. The method according to claim 1, wherein each of the first orifice and the second orifice includes at least one of a natural orifice, an incision and a cannula.

12. The method according to claim 1, wherein the first orifice is different from the second orifice.

13. The method of claim 1, wherein the hollow shaft is attached to a coupler projecting from the distal free end of the hollow shaft, said coupler having a diameter substantially equal to the hollow shaft diameter so that the hollow shaft and said coupler form a substantially uniform diameter which facilitates easy passage and maneuvering of the hollow shaft and said coupler into the body.

14. The method of claim 1, including the step of coupling the proximal end of the shaft with a motor to drive the shaft.

15. The method of claim 14, including the step of controlling operation of the motor by a computer controller.
