Surgical system for positioning prosthetic component and/or for constraining movement of surgical tool

1. A surgical system for positioning a prosthetic component on an anatomy of a patient, comprising:

the prosthetic component;

a surgical tool coupled to the prosthetic component;

a force system configured to provide at least some force to the surgical tool; and

a controller programmed to:

compare a target pose of the prosthetic component and an actual pose of the prosthetic component engaged by the surgical tool; and

generate control signals that cause the force system to allow movement of the surgical tool within a range of movement and provide haptic feedback to constrain a user's ability to manually move the surgical tool beyond the range of movement, wherein the haptic feedback resists movement of the surgical tool by the user that would cause substantial deviation between at least one aspect of the actual pose of the prosthetic component and a corresponding aspect of the target pose of the prosthetic component;

wherein the controller is programmed to generate control signals that cause the force system to maintain the haptic feedback as the user implants the prosthetic component on the anatomy.

2. The surgical system of claim 1 , wherein the at least one aspect of the actual pose and the corresponding aspect of the target pose include at least one of an angle, an axis, an orientation, a center of rotation, a boundary, and a depth.

3. The surgical system of claim 1 , wherein the target pose includes a planned pose of the prosthetic component implanted on the anatomy and an activation region.

4. The surgical system of claim 3 , wherein the activation region extends beyond a boundary of the planned pose.

5. The surgical system of claim 3 , wherein at least a portion of the planned pose and at least a portion of the activation region coincide.

6. The surgical system of claim 3 , wherein the activation region includes a cylindrical volume coaxial with an axis of the planned pose.

7. The surgical system of claim 3 , wherein the controller is further programmed to:

generate signals to activate the haptic feedback when at least a portion of the actual pose of the prosthetic component coincides with at least a portion of the activation region of the target pose.

8. The surgical system of claim 1 , wherein the controller is further programmed to:

initiate automatic control of the prosthetic component to substantially align the at least one aspect of the actual pose with the corresponding aspect of the target pose when the user moves the prosthetic component to override the haptic feedback.

9. The surgical system of claim 1 , wherein the tool comprises an end effector configured to be coupled to a robotic arm and including a first portion configured to engage the prosthetic component and a second portion configured to receive an impact force for implanting the prosthetic component on the anatomy of the patient.

10. The surgical system of claim 9 , wherein the end effector comprises:

a mounting portion configured to be coupled to a corresponding mounting portion of the robotic arm such that the mounting portions are fixed relative to one another; and

an operating member configured to translate relative to the coupled mounting portions when the user applies the impact force to the second portion of the end effector.

11. The surgical system of claim 10 , wherein the operating member is configured to translate in a region of constraint that includes a first location and a second location.

12. The surgical system of claim 11 , wherein the first and second locations are defined at least in part by a recess disposed on the operating member.

13. The surgical system of claim 11 , wherein the first location is defined at least in part by a recess disposed on the operating member and the second location is defined at least in part by a protrusion disposed on the operating member.

14. The surgical system of claim 13 , wherein the protrusion is disposed remotely from the recess.

15. The surgical system of claim 9 , wherein the first and second portions of the end effector comprise a distal end and a proximal end of an operating member, respectively.

16. The surgical system of claim 1 , further comprising a tracking device configured to be positioned on the anatomy of the patient, to track movement of the anatomy relative to the surgical tool during a surgical procedure and create position data representative of the position of the anatomy, and wherein the controller is programmed to generate the control signals based on the position data.
