Abstract

A surgical instrument includes an actuator. A member is connected with the actuator and includes a mating part releasably engageable with a tissue engaging element such that the member is interchangeable with a plurality of alternate tissue engaging elements. Systems, implants and methods are described.

Claims

1. A surgical instrument comprising:

an actuator; and

a member connected with the actuator and including a mating part releasably engageable with a tissue engaging element such that the member is interchangeable with a plurality of alternate tissue engaging elements.

2. A surgical instrument as recited in claim 1, further comprising a sleeve connected with the member and configured for disposal of the tissue engaging element.

3. A surgical instrument as recited in claim 1, wherein the sleeve is axially translatable relative to the member in a first direction and a second opposing direction.

4. A surgical instrument as recited in claim 1, wherein the sleeve is movable between an extended position for disposal about the tissue engaging element and a retracted position to expose the tissue engaging element.

5. A surgical instrument as recited in claim 1, wherein the actuator is motorized.

6. A surgical instrument as recited in claim 1, wherein the mating part includes a quick release connection with the tissue engaging element.

7. A surgical instrument as recited in claim 1, wherein the mating part includes a spheroidal joint connection with the tissue engaging element.

8. A surgical instrument as recited in claim 1, wherein the mating part includes an angled connection with the tissue engaging element.

9. A surgical instrument as recited in claim 1, wherein the mating part includes an articulated connection with the tissue engaging element.

10. A surgical instrument as recited in claim 1, wherein the mating part includes a female mating part engageable with a male mating part of the tissue engaging element.

11. A surgical instrument as recited in claim 1, wherein the mating part includes a friction fit element engageable with the tissue engaging element.

12. A surgical instrument as recited in claim 1, wherein the mating part includes a hex socket engageable with a hexagonal cross sectional portion of the tissue engaging element.

13. A surgical instrument as recited in claim 1, wherein the tissue engaging element includes a first surgical tool and a second surgical tool.

14. A surgical instrument as recited in claim 1, wherein the member includes an image guide that is configured to generate a signal representative of a position of the tissue engaging element.

15. A surgical instrument as recited in claim 1, wherein the member is configured for mating with alternate actuators.

16. A surgical instrument as recited in claim 1, wherein the plurality of alternate tissue engaging elements includes one or more of a wire brush, a drum rasp, a rotating cutter and a reamer.

17. A surgical instrument comprising:

a motorized actuator;

a quick release member engageable with the actuator and including a mating part releasably engageable with a tissue engaging element such that the member is interchangeable with a plurality of alternate tissue engaging elements that include one or more of a wire brush, a drum rasp, a rotating cutter and a reamer; and

a sleeve connected with the member and configured for disposal of the tissue engaging element.

18. A surgical system comprising:

a surgical instrument including an actuator and a member connected with the actuator, the member including a mating part releasably engageable with a tissue engaging element and a retractable sleeve configured for disposal of the tissue engaging element; and

a plurality of alternate tissue engaging elements such that the member is interchangeable with the plurality of tissue engaging elements.

19. A surgical system as recited in claim 18, wherein the mating part includes a quick release connection with the tissue engaging element.

20. A surgical system as recited in claim 18, wherein the plurality of alternate tissue engaging elements includes one or more of a wire brush, a drum rasp, a rotating cutter and a reamer.
