Abstract

Embodiments of a system and method for surgical tracking and control are generally described herein. A system may include a robotic arm configured to allow interactive movement and controlled autonomous movement of an end effector, a cut guide mounted to the end effector of the robotic arm, the cut guide configured to guide a surgical instrument within a plane, a tracking system to determine a position and an orientation of the cut guide, and a control system to permit or prevent interactive movement or autonomous movement of the end effector.

Claims (20)

1. A system for surgical tracking and control comprising:

a robotic arm configured to allow interactive movement and execute controlled autonomous movement of an end effector;

a cut guide mounted to the end effector of the robotic arm, the cut guide configured to guide a surgical instrument within a plane;

a tracking system configured to determine a position and an orientation of the cut guide relative to a coordinate system; and

a control system configured to:

automatically make a determination that the cut guide is in a cutting position or aligned with a cutting line or a cutting plane based on the position;

in response to said determination, permit interactive movement of the end effector and prevent autonomous movement of the end effector, and wherein the control system is further configured to, after receiving an indication to activate autonomous movement, cause, in response to said determination indicating the cut guide is aligned with the cutting line or the cutting plane, autonomous movement of the end effector to the cutting position.

2. The system of claim 1 , wherein, after moving to the cutting position, the cut guide is further configured to be moveable along the cutting plane and to be prevented from moving outside of the cutting plane.

3. The system of claim 2 , wherein the cut guide is further configured to be allowed to enter a safety zone while in the cutting plane.

4. The system of claim 1 , wherein the control system is further configured to lock the cut guide into the cutting position after causing the cut guide to move to the cutting position.

5. The system of claim 4 , wherein the control system is further configured to move the cut guide relative to a tracked movement of a target object when the cut guide is locked, such that the cut guide is locked into the cutting position relative to the target object.

6. The system of claim 4 , wherein to lock the cut guide into the cutting position, the control system is further configured to lock the cut guide into the cutting position in response to receiving a selection via a user interface.

7. The system of claim 1 , wherein the control system is further configured to lock the cut guide into the cutting position after interactive positioning of the cut guide, the interactive positioning occurring after the autonomous movement.

8. The system of claim 1 , wherein the control system further comprises a user interface, the user interface including a selectable indication that upon selection, causes the control system to autonomously move the cut guide to the cutting position.

9. The system of claim 8 , wherein the cutting position is a predetermined cutting position selected by a surgeon relative to a target object, the predetermined cutting position aligning a first slot of the cut guide with a cut plane.

10. The system of claim 8 , wherein the control system is further configured to:

in response to said determination, activate the selectable indication.

11. The system of claim 1 , wherein the control system is further configured to automatically make the determination that the cut guide is in the cutting position or aligned with the cutting line or the cutting plane using anatomical landmarks of a target bone.

12. The system of claim 1 , wherein the tracking system is further configured to determine a position and an orientation of a target object relative to the coordinate system.

13. The system of claim 12 , wherein the position and the orientation of the cut guide are determined relative to the position and the orientation of the target object and wherein the coordinate system is determined from the position and the orientation of the target object.
