Abstract

An implant positioning device and a method of using the device are described. The positioning device includes an end effector configured to contact an implant component during a surgical procedure, the end effector connected to an actuator for imparting an impact force to the implant component during the surgical procedure, a motor mechanically connected to the actuator and configured to move the actuator to produce one or more impacts on the end effector, thereby imparting the impact force to the implant component, and a control circuit coupled to the motor. The control circuit is configured to generate at least one motor control signal, transfer the at least one motor control signal to the motor, and, as a result of the at least one motor control signal, cause the motor to move the actuator to produce one or more impacts on the end effector.

Claims (43)

1. A method for inserting an implant component during a surgical procedure, the method comprising:

obtaining, by a surgical control system, an implant plan comprising a desired implant position within an implant host, wherein the desired implant position comprises a location and an orientation of the implant component within the implant host;

receiving, at a control circuit in operable communication with the surgical control system, one or more parameters indicating a tracked location of an implant positioning device comprising a positioning arm having a proximal fixed portion and a distal movable portion;

responsive to determining that the implant component has not reached the desired implant position based on the received one or more parameters and a known relationship between the implant positioning device and the implant component, generating, at the control circuit, at least one motor control signal;

receiving, at a motor operably connected to the control circuit, the at least one motor control signal; and

moving, by the motor, a plurality of linear actuators mechanically connected to the motor and the distal movable portion as a result of the at least one motor control signal to thereby impart impact forces on localized portions on a circumference of an end effector to induce during insertion a rotational motion on the implant component coupled to the end effector via an implant retention device.

2. The method of claim 1 , further comprising

establishing a communication link between the control circuit and the surgical control system; and

receiving, by the control circuit, at least one system control signal from the surgical control system, the system control signal for controlling insertion of the implant component by the implant positioning device.

3. The method of claim 2 , wherein the at least one system control signal comprises an impact frequency indicating how frequently one or more of the linear actuator are to impart one or more of the impact, wherein imparting the one or more of the impact forces comprises imparting the one or more of the impact forces at the impact frequency.

4. The method of claim 1 , wherein the linear actuators are coupled between the distal movable portion and the proximal fixed portion.

5. The method of claim 1 , wherein the surgical procedure is a hip replacement surgery.

6. The method of claim 5 , wherein the implant component is a prosthetic acetabular cup.

7. A method for inserting an implant component during a surgical procedure, the method comprising:

obtaining, by a surgical control system, an implant plan comprising a desired implant position within an implant host;

establishing a communication link between a control circuit and the surgical control system;

receiving, by the control circuit, at least one system control signal from the surgical control system, wherein the at least one system control signal comprises an impact force to be applied to an implant positioning device;

receiving, by the control circuit in operable communication with the surgical control system, one or more parameters indicating a tracked location of an implant positioning device comprising a positioning arm having a distal movable portion;

responsive to determining that the implant component has not reached the desired implant position based on the received one or more parameters and a known relationship between the implant positioning device and the implant component, generating, at the control circuit, at least one motor control signal;

receiving, at a motor operably connected to the control circuit, the at least one motor control signal; and

moving, by the motor, a plurality of linear actuators mechanically connected to the motor and the distal movable portion as a result of the at least one motor control signal to thereby impart impact forces on localized portions on a circumference of an end effector to induce during insertion a rotational motion on the implant component.

8. The method of claim 7 , wherein the at least one system control signal comprises an impact frequency indicating how frequently one or more of the linear actuator are to impart one or more of the impact forces, wherein imparting the one or more of the impact forces comprises imparting the one or more of the impact forces at the impact frequency.

9. The method of claim 7 , wherein the positioning arm further comprises a proximal fixed portion.

10. The method of claim 7 , wherein the surgical procedure is a hip replacement surgery.

11. The method of claim 10 , wherein the implant component is a prosthetic acetabular cup.

12. The method of claim 7 , wherein the desired implant position comprises a location and an orientation of an implant component within the implant host.

13. The method of claim 7 , wherein the implant component is coupled to the end effector via an implant retention device.

14. A method for inserting an implant component during a surgical procedure, the method comprising:

obtaining, by a surgical control system, an implant plan comprising a desired implant position within an implant host;

receiving, at a control circuit in operable communication with the surgical control system, one or more parameters indicating a tracked location of an implant positioning device comprising a positioning arm having a distal movable portion;

responsive to determining that the implant component has not reached the desired implant position based on the received one or more parameters and a known relationship between the implant positioning device and the implant component, generating, at the control circuit, at least one motor control signal;

receiving, at a motor operably connected to the control circuit, the at least one motor control signal; and

moving, by the motor, a plurality of linear actuators mechanically connected to the motor and the distal movable portion as a result of the at least one motor control signal to thereby impart impact forces on localized portions on a circumference of an end effector to induce during insertion a rotational motion on the implant component.

15. The method of claim 14 , further comprising

establishing a communication link between the control circuit and the surgical control system; and

receiving, by the control circuit, at least one system control signal from the surgical control system, the system control signal for controlling insertion of the implant component by the implant positioning device.

16. The method of claim 15 , wherein the at least one system control signal comprises an impact frequency indicating how frequently one or more of the linear actuator are to impart one or more of the impact forces, wherein imparting the one or more of the impact forces comprises imparting the one or more of the impact forces at the impact frequency.

17. The method of claim 14 , wherein the positioning arm further comprises a proximal fixed portion.

18. The method of claim 17 , wherein the linear actuators are coupled between the distal movable portion and the proximal fixed portion.

19. The method of claim 14 , wherein the surgical procedure is a hip replacement surgery.

20. The method of claim 19 , wherein the implant component is a prosthetic acetabular cup.

21. The method of claim 14 , wherein the desired implant position comprises a location and an orientation of an implant component within the implant host.

22. The method of claim 14 , wherein the implant component is coupled to the end effector via an implant retention device.
