Abstract

Apparatus, system, and method are disclosed herein for controlling movement of an artificial orthopedic joint prosthesis in a mammalian subject. The apparatus, system, or method includes an orthopedic brace configured to control movement of an orthopedic joint prosthesis. The apparatus, system, or method includes one or more sensors and one or more controllers in communication with the one or more sensors. The one or more sensors are configured to detect a change in an orientation of a subject'"'"'s position in an environment and configured to detect one or more alignment orientations of the orthopedic joint prosthesis.

Claims

1. An apparatus comprising:

an orthopedic brace adapted to be external to a subject, the orthopedic brace including a first member and a second member, wherein the first member is configured to control movement of a first component of an orthopedic joint prosthesis relative to the second member and the second member is configured to control movement of a second component of the orthopedic joint prosthesis;

at least one of an imaging device, an inertial sensor, or a proximity sensor configured to detect a change in an orientation of the subject'"'"'s position in an environment and at least one additional sensor configured to detect one or more alignment orientations of the first component relative to the second component of the orthopedic joint prosthesis by transcutaneously detecting at least one portion of the internal orthopedic joint prosthesis;

one or more controllers in communication with the at least one of the imaging device, the inertial sensor, or the proximity sensor and the at least one additional sensor, wherein the at least one of the imaging device, the inertial sensor, or the proximity sensor reports the change in the orientation of the subject'"'"'s position in the environment to the one or more controllers, and the at least one additional sensor reports the one or more alignment orientations to the one or more controllers, and the one or more controllers control movement of the first member relative to the second member of the orthopedic brace, wherein the orthopedic brace is configured to adjust the one or more alignment orientations of the first component relative to the second component of the orthopedic joint prosthesis; and

one or more force-applying elements to control the movement of the first member relative to the second member, wherein the one or more force-applying elements in response to the one or more controllers are configured to permit unrestrained motion of the orthopedic joint prosthesis under a first set of the one or more alignment orientations and are configured to permit restrained motion of the orthopedic joint prosthesis under a second set of the one or more alignment orientations.

2. The apparatus of claim 1, wherein the second set of the one or more alignment orientations includes a separation of the first component relative to the second component of the orthopedic joint prosthesis.

3. The apparatus of claim 1, wherein the restrained motion comprises a motion from the second set of the one or more alignment orientations towards the first set of the one or more alignment orientations.

4. The apparatus of claim 1, wherein the restrained motion comprises a reduction of one or more alignment differences between the second set of the one or more alignment orientations and the first set of the one or more alignment orientations.

5. The apparatus of claim 1, wherein the at least one additional sensor comprises one or more sonic energy sensors.

6. The apparatus of claim 5, wherein the one or more sonic energy sensors comprise one or more ultrasonic sensors.

7. The apparatus of claim 6, wherein the one or more ultrasonic sensors are configured to determine a separation between the first component and the second component of the orthopedic joint prosthesis.

8. The apparatus of claim 6, wherein the one or more ultrasonic sensors are configured to determine a movement between the first component and the second component of the orthopedic joint prosthesis.

9. The apparatus of claim 1, wherein the at least one additional sensor is configured to detect one or more of positioning, disposition, attitude, or movement of the orthopedic joint prosthesis.

10. The apparatus of claim 1, wherein the one or more controllers are configured to be activated in response to a signal from the at least one of the imaging device, the inertial sensor, or the proximity sensor or the at least one additional sensor.

11. The apparatus of claim 1, comprising a power source.

12. The apparatus of claim 1, comprising a receiver configured to receive wireless signals from the at least one of the imaging device, the inertial sensor, or the proximity sensor or the at least one additional sensor.

13. The apparatus of claim 1, comprising a receiver configured to receive wire-based signals from the at least one of the imaging device, the inertial sensor, or the proximity sensor or the at least one additional sensor.

14. The apparatus of claim 1, comprising a transmitter configured to transmit a request for data from the at least one of the imaging device, the inertial sensor, or the proximity sensor or the at least one additional sensor.

15. The apparatus of claim 1, comprising the one or more controllers configured to use information from a model of one or more of a limb or a joint of the mammalian subject, wherein the one or more controllers are configured to predict future actions or consequences of movement of the brace.

16. An apparatus comprising:

an orthopedic brace, the orthopedic brace including a first member and a second member, wherein the first member is configured to control movement of a first component of an orthopedic joint prosthesis relative to the second member and the second member is configured to control movement of a second component of the orthopedic joint prosthesis;

at least one of an imaging device, an inertial sensor, or a proximity sensor configured to detect a change in an orientation of the subject'"'"'s position in an environment;

at least one additional sensor configured to detect one or more alignment orientations of the first component relative to the second component of the orthopedic joint prosthesis by transcutaneously detecting at least one portion of the internal orthopedic joint prosthesis; and

one or more controllers in communication with the at least one of the imaging device, the inertial sensor, or the proximity sensor and the at least one additional sensor, wherein the at least one of the imaging device, the inertial sensor, or the proximity sensor reports the change in the orientation of the subject'"'"'s position in the environment to the one or more controllers, and the at least one additional sensor reports the one or more alignment orientations to the one or more controllers, and the one or more controllers control movement of the first member relative to the second member of the orthopedic brace, wherein the orthopedic brace is configured to adjust the one or more alignment orientations of the first component relative to the second component of the orthopedic joint prosthesis via action of one or more force-applying elements, wherein the one or more force-applying elements in response to the one or more controllers are configured to permit unrestrained motion of the orthopedic joint prosthesis under a first set of the one or more alignment orientations and are configured to permit restrained motion of the orthopedic joint prosthesis under a second set of the one or more alignment orientations.
