Abstract

A method of using a robotic guidance system for performing surgery on a spine is provided. The method includes utilizing a computerized tomographic scan image of a location on a spinal column of a patient, such that the computerized tomographic scan image is connected to a computer and visible on a monitor connected to the computer. The method also includes attaching a coupling component to the spinal column of the patient, coupling a marker to the coupling component, and imaging, with a fluoroscope, the view of the spinal column of the patient, wherein the fluoroscope image is transmitted to the computer and visible on the monitor and the at marker is clearly visible in the fluoroscope image. The method also includes positioning a cannula, with a robotic mechanism, to a first position relative to a vertebra in the spinal column of the patient, drilling a passage through the cannula into bone of the vertebra in the spinal column of the patient, inserting a guidewire through the cannula into the passage in the bone of the vertebra in the spinal column of the patient, and positioning a screw into the bone of the vertebra in the spinal column of the patient.

First claim

What is claimed is:

1. A method of fastening at least first and second portions of body tissue together, the method comprising:
imparting, using an adaptive arm of a robotic mechanism, a clamping force to the first and second portions of body tissue suitable to press the first and second portions against one another;
generating, using a force measurement system associated with the adaptive arm, a clamping force signal indicative of the clamping force imparted by the adaptive arm to the first and second portions of body tissue;
receiving, using a computer in communication with the force measurement system and the robotic mechanism, the clamping force signal from the force measurement system;
determining, using the computer and the received clamping force signal, that the clamping force imparted by the adaptive arm to the first and second portions of body tissue has a predetermined magnitude; and
fastening, after said determining and simultaneously with the clamping force imparted by the adaptive arm to the first and second portions of body tissue having the predetermined magnitude, the first and second portions of body tissue together using the adaptive arm.

2. The method of fastening at least first and second portions of body tissue together as set forth in claim 1 , wherein said fastening comprises inserting at least one fastener into the first and second portions using the adaptive arm.

3. The method of fastening at least first and second portions of body tissue together as set forth in claim 2 , wherein the at least one fastener comprises at least one staple.

4. The method of fastening at least first and second portions of body tissue together as set forth in claim 1 , wherein said fastening comprises applying at least one fastener to the first and second portions of body tissue.

5. The method of fastening at least first and second portions of body tissue together as set forth in claim 4 , wherein the at least one fastener is formed from a polymer.

6. A method of fastening at least first and second portions of body tissue together, the method comprising:
applying, using a robotic mechanism, a force to the first and second portions of body tissue suitable to press the first and second portions against one another;
generating, using a sensor associated with the robotic mechanism, a fastening signal indicative of the first and second portions being suitable for being fastened to one another during said applying a force to the first and second portions of body tissue;
receiving, using a computer in communication with the sensor and the robotic mechanism, the fastening signal from the sensor;
determining, using the computer and the received fastening signal, that the first and second portions of body tissue are suitable for being fastened to one another; and
fastening, after said determining, the first and second portions of body tissue together using a fastener applied by the robotic mechanism.

7. The method of fastening at least first and second portions of body tissue together as set forth in claim 6 , wherein the fastener comprises at least one staple.

8. The method of fastening at least first and second portions of body tissue together as set forth in claim 6 , wherein said applying a force to the first and second portions of body tissue comprises applying, using the robotic mechanism, a compressive force to the first and second portions of body tissue.

9. The method of fastening at least first and second portions of body tissue together as set forth in claim 6 , wherein said fastening comprises inserting, using the robotic mechanism, the fastener through each of the first and second portions of body tissue.

10. The method of fastening at least first and second portions of body tissue together as set forth in claim 6 , wherein said fastening includes engaging, using the robotic mechanism, an outer surface of the first portion of body tissue with a first part of the fastener, and engaging, using the robotic mechanism, an outer surface of the second portion of body tissue with a second part of the fastener.

11. The method of fastening at least first and second portions of body tissue together as set forth in claim 10 , wherein said engaging, using the robotic mechanism, an outer surface of the second portion of body tissue with a second part of the fastener comprises deforming, using the robotic mechanism, the second part of the fastener.

12. The method of fastening at least first and second portions of body tissue together as set forth in claim 6 , wherein said fastening, after said determining, the first and second portions of body tissue together comprises deforming, using the robotic mechanism, a part of the fastener.

13. The method of fastening at least first and second portions of body tissue together as set forth in claim 12 , wherein the deformed part of the fastener engages an outer surface of the second portion of body tissue.

14. The method of fastening at least first and second portions of body tissue together as set forth in claim 6 , wherein said applying a force to the first and second portions of body tissue and said fastening are performed using a single adaptive arm of the robotic mechanism, wherein said single adaptive arm is received in a cannula in a patient's body.

15. The method of fastening at least first and second portions of body tissue together as set forth in claim 6 , wherein said fastening is performed during said applying a force to the first and second portions of body tissue.

16. The method of fastening at least first and second portions of body tissue together as set forth in claim 6 , wherein said applying a force to the first and second portions of body tissue and said fastening are performed using a single adaptive arm of the robotic mechanism.

17. The method of fastening at least first and second portions of body tissue together as set forth in claim 16 , wherein said applying a force to the first and second portions of body tissue is performed using a first drive mechanism of the robotic mechanism, wherein said fastening is performed using a second drive mechanism of the robotic mechanism.

18. The method of fastening at least first and second portions of body tissue together as set forth in claim 17 , wherein the first drive mechanism and the second drive mechanism are operated independently of one another.

19. The method of fastening at least first and second portions of body tissue together as set forth in claim 17 , wherein the first drive mechanism is actuated independently of and before the second drive mechanism so that the first and second portions of body tissue are suitably pressed against one another before and during said fastening.

20. The method of fastening at least first and second portions of body tissue together as set forth in claim 6 , wherein said applying a force to the first and second portions of body tissue is performed using a first drive mechanism of the robotic mechanism, wherein said fastening is performed using a second drive mechanism of the robotic mechanism.

21. The method of fastening at least first and second portions of body tissue together as set forth in claim 20 , wherein said first drive mechanism applies a predetermined force to the first and second portions of body tissue.

22. The method of fastening at least first and second portions of body tissue together as set forth in claim 20 , wherein the first drive mechanism is actuated independently of and before the second drive mechanism so that the first
