Surgical instrument system and method
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.
1. A surgical instrument comprising:
a tissue engaging element comprising a wire brush;
a motorized actuator;
a member connected with the actuator and including a mating part releasably engageable with the tissue engaging element, the member being configured to be interchangeable with a plurality of alternate tissue engaging elements; and
a sleeve connected with the member and configured for disposal of the tissue engaging element, the sleeve being movable between an extended position for disposal about the tissue engaging element and a retracted position to expose the tissue engaging element.
2. 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.
3. 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.
4. A surgical instrument as recited in claim 1 , wherein the tissue engaging element includes a first surgical tool and a second surgical tool.
5. 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.
6. A surgical instrument as recited in claim 1 , wherein the member is configured for mating with alternate actuators.
7. 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.
8. A surgical instrument comprising:
a tissue engaging element comprising a drum rasp;
a motorized actuator;
a member connected with the actuator, the member including a mating part releasably engageable with the tissue engaging element, the member being configured to be interchangeable with a plurality of alternate tissue engaging elements; and
a sleeve connected with the member and configured for disposal of the tissue engaging element, the sleeve being movable between an extended position for disposal about the tissue engaging element and a retracted position to expose the tissue engaging element.
9. A surgical instrument as recited in claim 8 , wherein the mating part includes a quick release connection with the tissue engaging element.
10. A surgical instrument as recited in claim 8 , wherein the drum rasp comprises a rigid cylinder having cutting blades.
11. A surgical instrument comprising;
a tissue engaging element comprising a reamer including a hollow drill;
a motorized actuator;
a member connected with the actuator and including a mating part releasably engageable with the tissue engaging element, the member being configured to be interchangeable with a plurality of alternate tissue engaging elements; and
a sleeve connected with the member and configured for disposal of the tissue engaging element, the sleeve being movable between an extended position for disposal about the tissue engaging element and a retracted position to expose the tissue engaging element.
12. A surgical instrument as recited in claim 1 , wherein the tissue engaging element is encased within the sleeve when the sleeve is in the extended position.
13. A surgical instrument as recited in claim 1 , wherein a distal end of the sleeve extends distal to a working end of the tissue engaging element when the sleeve is in the extended position, the working end extending distal to the distal end when the sleeve is in the retracted position.
