Abstract

A retractor mounting assembly including an end-effector having a body extending between first and second faces. The first face is configured for attachment to an interface plate on the robotic arm of a surgical robot. The second face defines an arm mount. An arm extending between first and second ends with the first end configured for attachment to the end-effector arm mount and the second end providing a retractor mount configured for supportive attachment of a retractor.

First claim

What is claimed is:

1. A retractor mounting assembly comprising:
an end-effector having a body extending between first and second faces, the first face configured for attachment to an interface plate on the robotic arm of a surgical robot, and the second face defining an arm mount; and
an arm extending between first and second ends, the first end configured for attachment to the end-effector arm mount and the second end providing a retractor mount configured for supportive attachment of a retractor,
wherein the end-effector includes a lockout actuator.

2. The retractor mounting assembly according to claim 1 wherein the first face includes a clamp configured to clamp the end-effector to the interface plate.

3. The retractor mounting assembly according to claim 1 wherein the robotic arm includes a pair of arms pivotally connected to one another, one of the arms defining the first end and the other arm defining the retractor mount.

4. The retractor mounting assembly according to claim 3 wherein an adjustment screw interconnects the pair of arms and defines a pivot point therebetween.

5. The retractor mounting assembly according to claim 1 wherein the retractor mount is defined by a retractor mounting component which is detachable from the arm.

6. The retractor mounting assembly according to claim 5 wherein the retractor mounting component complements an attachment member on the retractor.

7. The retractor mounting assembly according to claim 1 wherein the lockout actuator is configured to cause actuation of a lockout device on the surgical robot upon attachment of the end-effector to the interface plate.

8. The retractor mounting assembly according to claim 7 wherein the lockout actuator is a wireless electro-mechanical device configured to send a lockout signal upon attachment of the end-effector to the interface plate.

9. A retractor mounting system comprising:
a surgical robot having a robotic arm defining an interface plate; and
a retractor mounting assembly comprising:
an end-effector having a body extending between first and second faces, the first face configured for attachment to the interface plate, and the second face defining an arm mount; and
an arm extending between first and second ends, the first end configured for attachment to the end-effector arm mount and the second end providing a retractor mount configured for supportive attachment of a retractor,
wherein the end-effector includes a lockout actuator.

10. The retractor mounting system according to claim 9 wherein the first face includes a clamp configured to clamp the end-effector to the interface plate.

11. The retractor mounting system according to claim 10 wherein the clamp is configured to clamp over a sterile drape about the arm without damaging the sterile drape.

12. The retractor mounting system according to claim 9 wherein the robotic arm includes a pair of arms pivotally connected to one another, one of the arms defining the first end and the other arm defining the retractor mount.

13. The retractor mounting system according to claim 12 wherein an adjustment screw interconnects the pair of arms and defines a pivot point therebetween.

14. The retractor mounting system according to claim 1 wherein the retractor mount is defined by a retractor mounting component which is detachable from the arm.

15. The retractor mounting system according to claim 14 wherein the retractor mounting component complements an attachment member on the retractor.

16. The retractor mounting system according to claim 9 wherein the lockout actuator is configured to cause actuation of a lockout device on the surgical robot upon attachment of the end-effector to the interface plate.

17. The retractor mounting system according to claim 16 wherein the lockout actuator is a wireless electro-mechanical device configured to send a lockout signal upon attachment of the end-effector to the interface plate.

18. A method of implanting a implant utilizing a retractor mounting system including a surgical robot having a robotic arm defining an interface plate; and a retractor mounting assembly comprising: an end-effector having a lockout actuator and a body extending between first and second faces, the first face configured for attachment to the interface plate, and the second face defining an arm mount; and an arm extending between first and second ends, the first end configured for attachment to the end-effector arm mount and the second end providing a retractor mount, the method comprising:
attaching a retractor to the retractor mount;
moving the robot arm and the arm to position and support the retractor at a desired location;
actuating the retractor to create a surgical port; and
implanting the implant through the surgical port utilizing a surgical tool.

19. The method according to claim 18 further comprising the step of locking the position of the robotic arm once the retractor is positioned in a desired position.

20. The method according to claim 18 further comprising tracking the position of the surgical tool via the surgical robot.
