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 surgical robotic system comprising:
a base coupled to a robot arm;
a retractor mounting assembly coupled to the robot arm, the 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 robot arm, and the second face defining an arm mount;
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, and
a computer system operationally configured to control the surgical robotic system,
wherein the end-effector includes a locking actuator,
wherein the locking actuator is positioned within a hollow chamber of a mounting post such that the surface of an end cap is flush with an end of the mounting post.

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 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 locking 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. 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.

10. The retractor mounting system according to claim 9 wherein the retractor mounting component complements an attachment member on the retractor.

11. 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;
a computer system for controlling the surgical robot;
wherein the end-effector includes a locking actuator,

wherein the locking actuator is positioned within a hollow chamber of a mounting post such that the surface of an end cap is flush with an end of the mounting post.

12. The retractor mounting system according to claim 11 wherein the first face includes a clamp configured to clamp the end-effector to the interface plate.

13. The retractor mounting system according to claim 12 wherein the clamp is configured to clamp over a sterile drape about the arm without damaging the sterile drape.

14. The retractor mounting system according to claim 11 wherein the 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.

15. The retractor mounting system according to claim 14 wherein an adjustment screw interconnects the pair of arms and defines a pivot point therebetween.

16. The retractor mounting system according to claim 11 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 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
wherein a locking actuator is positioned within a hollow chamber of a mounting post such that the surface of an end cap is flush with an end of the mounting post.

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.
