Abstract

A device for moving a knee joint in a body of a patient is provided. The device includes a first arm member coupled to a first leg support configured to support an upper portion of a leg of the patient, a second arm member coupled to a second leg support configured to support at least one of a lower portion of a leg and a foot of the patient, and a control assembly operatively connected to the first and second arm members and configured to selectively move the second arm member relative to the first arm member. The control assembly includes a first motorized drive assembly coupled to the first and second arm members and operable to drive movement of the second arm member relative to the first arm member and a second motorized drive assembly coupled to the first and second arm members and operable to drive movement of the second arm member relative to the first arm member.

Claims

1. A device for moving a knee joint in a body of a patient, the device comprising:

a first arm member coupled to a first leg support configured to support an upper portion of a leg of the patient;

a second arm member coupled to a second leg support configured to support at least one of a lower portion of a leg and a foot of the patient;

a control assembly operatively connected to the first and second arm members and configured to selectively move the second arm member relative to the first arm member, the control assembly comprising;

a first motorized drive assembly coupled to the first and second arm members and operable to drive movement of the second arm member relative to the first arm member; and

a second motorized drive assembly coupled to the first and second arm members and operable to drive movement of the second arm member relative to the first arm member.

2. The device for moving a knee joint in a body of a patient as set forth in claim 1, wherein the first and second motorized drive assemblies include at least one of a hydraulic and pneumatic motor.

3. The device for moving a knee joint in a body of a patient as set forth in claim 1, further comprising a monitor having a storage medium, the monitor configured to track and store usage information of the device.

4. The device for moving a knee joint in a body of a patient as set forth in claim 3, wherein the monitor further comprises a display for displaying positional information of the device.

5. The device for moving a knee joint in a body of a patient as set forth in claim 3, wherein the monitor further comprises a data transfer component for wirelessly transferring usage information of the device.

6. The device for moving a knee joint in a body of a patient as set forth in claim 1, further comprising a locking mechanism configured to prevent actuation of at least one of the first motorized drive assembly and the second motorized drive assembly.

7. The device for moving a knee joint in a body of a patient as set forth in claim 1, further comprising a lower leg strap for securing at least one of the lower portion of a leg and the foot of the patient to the second leg support.

8. The device for moving a knee joint in a body of a patient as set forth in claim 1, further comprising an upper leg strap for securing an upper portion of a leg of the patient to the first leg support.

9. The device for moving a knee joint in a body of a patient as set forth in claim 1, further comprising a timer.

10. The device for moving a knee joint in a body of a patient as set forth in claim 1, wherein the second drive assembly is configured to move the second arm member to at least one of increase and decrease a force exerted by the device.

11. The device for moving a knee joint in a body of a patient as set forth in claim 1, wherein the first motorized drive assembly includes a drive element configured to selectively move the second arm member while the second motorized drive assembly is maintained in a fixed position relative to the first and second arm members.

12. The device for moving a knee joint in a body of a patient as set forth in claim 1, wherein the second motorized drive assembly includes a drive element configured to selectively move the second arm member while the first motorized drive assembly is maintained in a fixed position relative to the first and second arm members.

13. The device for moving a knee joint in a body of a patient as set forth in claim 1 wherein the second arm member further comprises a telescoping member for adjusting the length of the second arm member.

14. A device for moving a leg of a user into flexion and extension, the device comprising:

a base member;

a first arm member coupled to the base member;

a second arm member coupled the first arm member;

a motorized drive assembly mounted to the base member and pivotably coupled to the second arm member, the drive assembly configured to selectively move the second arm member relative to the first arm member;

a motorized force application assembly coupled to the first arm member, the motorized force application assembly configured to control a force exerted by the device; and

a locking mechanism coupled to at least one of the first and second arm members, the locking mechanism configured to prevent actuation of the first motorized drive assembly.

15. The device for moving a leg of a user into flexion and extension as set forth in claim 14, wherein the first arm member is coupled to a first leg support configured to support an upper portion of the leg and the second arm member is coupled to a second leg support configured to support at least one of a lower portion of the leg and a foot.

16. The device for moving a leg of a user into flexion and extension as set forth in claim 14, further comprising a controller configured to enable a user to selectively move the second arm member to allow for angle control of the first and second arm members.

17. The device for moving a leg of a user into flexion and extension as set forth in claim 14, wherein the drive assembly enables incremental movement of the device to move the leg of a user.

18. The device for moving a leg of a user into flexion and extension as set forth in claim 17, wherein the monitor further comprises a data transfer component for wirelessly transferring usage information of the device.

19. The device for moving a leg of a user into flexion and extension as set forth in claim 17, wherein the monitor further comprises a display for displaying degrees of at least one of flexion and extension.

20. The device for moving a leg of a user into flexion and extension as set forth in claim 14, further comprising a monitor having a storage medium, the monitor configured to track and store usage information of the device.

21. The device for moving a leg of a user into flexion and extension as set forth in claim 14, wherein the motorized drive assembly includes at least one of a hydraulic and pneumatic motor.

22. The device for moving a leg of a user into flexion and extension as set forth in claim 14, further comprising at least one position sensor for monitoring the relative positional degrees of the first and second arm members.

23. A method for moving a leg of a user using a device, the method comprising:

securing a portion of an upper leg to a first leg support that is coupled to a first arm member;

securing at least one of a lower portion of a leg and a foot to a second leg support that is coupled to a second arm member that is coupled to the first arm member; and

operating a controller coupled to a motorized drive assembly and a motorized force application assembly configured to enable a user to selectively move the second arm member from a first position relative to the first arm member to a second position relative to the first arm member.

24. A method for moving a leg of a user using a device as set forth in claim 23, further comprising positioning a locking mechanism coupled to at least one of the first and second arm members such that the locking mechanism prevents the second arm member from moving past a second position relative to the first arm member.
