Abstract

Embodiments may include a traction system, for example a cervical traction system for a neck of a user. Systems may include a housing assembly, plate assembly, handle assembly, and cable assembly. The housing assembly may include a drive assembly. The plate assembly may be operatively connected to the drive assembly. The handle assembly may be operatively connected to the drive assembly. The handle assembly may be configured to actuate movement of the plate assembly relative to the housing assembly. Embodiments may be configured to apply traction to the neck thereby providing a distraction distance or force to a portion of the cervical spine.

Claims

1. A cervical traction system for a neck of a user, the system comprising:

a plate assembly including first and second supports configured to engage a portion of a head of the user, and first and second transverse drive members configured to move the respective first and second supports to adjust a transverse distance between the first and second supports;

a housing assembly including a longitudinal drive member configured to move the plate assembly relative to the housing assembly; and

a handle assembly operatively connected to the longitudinal drive member,

wherein movement of the plate assembly is configured to urge the first and second supports against the head to apply traction to the neck, and

wherein the longitudinal drive member and plate assembly are releasably connected and selectively releasable to allow sliding movement of the plate assembly along a length of the longitudinal drive member to adjust a position of the plate assembly relative to the housing, the sliding movement of the plate assembly being limited by the longitudinal drive member when the plate assembly and longitudinal drive member are connected.

2. The system of claim 1, the plate assembly includes first and second knobs operative to actuate the respective first and second transverse drive members to adjust the first and second supports.

3. The system of claim 1, wherein the handle assembly comprises a trigger configured to actuate the longitudinal drive member.

4. The system of claim 1, wherein the handle assembly comprises a knob configured to actuate the longitudinal drive member.

5. The system of claim 1, wherein the longitudinal drive member includes a worm gear or pulley.

6. The system of claim 1, wherein the longitudinal drive member is non-pneumatic.

7. The system of claim 1, wherein movement of the plate assembly is configured to apply traction to a portion of the cervical spine.

8. A cervical traction system for a neck of a user, the system comprising:

a housing assembly including a drive assembly;

a plate assembly operatively connected to the drive assembly and comprising at least one support configured to engage a portion of a head of the user, wherein the drive assembly is configured to drive movement of the plate assembly relative to the housing assembly;

a cable assembly operatively connected to the drive assembly, wherein the cable assembly is configured to drive movement of the drive assembly;

a handle assembly operatively connected to the cable assembly, wherein the handle assembly is configured to actuate movement of the cable assembly to drive movement of the drive assembly, which in turn drives movement of the plate assembly relative to the housing assembly, wherein movement of the plate assembly is configured to apply traction to the neck; and

a clutch operatively connected between the handle assembly and the plate assembly to prevent actuation of the handle assembly from causing driven movement of the plate assembly when the amount of traction applied to the neck exceeds a traction limit.

9. The system of claim 8, wherein the at least one support includes a first support and a second support, the system further comprising a transverse drive member configured to adjust a transverse distance between the first and second supports.

10. The system of claim 8, wherein the handle assembly comprises a trigger configured to actuate movement of the cable assembly.

11. The system of claim 8, wherein the handle assembly comprises a knob configured to actuate movement of the cable assembly.

12. The system of claim 8, wherein the drive assembly includes a worm gear or pulley.

13. The system of claim 8, wherein the drive assembly is non-pneumatic.

14. The system of claim 8, wherein movement of the plate assembly is configured to apply traction to a portion of the cervical spine.

15. A method of using a cervical traction device for a neck of a patient, the method comprising:

providing the cervical traction device including a housing assembly having a longitudinal drive, a plate assembly including at least one support configured to engage a portion of a head of the patient, a cable assembly operatively connected to the longitudinal drive, a handle assembly operatively connected to the cable assembly, and a clutch assembly operatively connected between the handle assembly and the plate assembly;

positioning a neck of the patient with respect to the plate assembly and the at least one support;

actuating a traction knob or a trigger of the handle assembly to actuate movement of the cable assembly to drive movement of the longitudinal drive, which in turn drives movement of the longitudinal drive to move the plate assembly relative to the housing assembly to provide a traction force to at least a portion of the neck; and

using the clutch to prevent actuation of the handle assembly from causing driven movement of the plate assembly when the amount of traction applied to the neck exceeds a traction limit.

16. The method of claim 15, further comprising rotating a limit knob to adjust the traction limit.

17. The method of claim 15, further comprising rotating a support knob of the housing assembly to adjust a transverse distance between first and second supports of the at least one support to engage at least a portion of the neck.

18. The method of claim 15, wherein the longitudinal drive includes a worm gear or pulley.

19. The method of claim 15, wherein the longitudinal drive is non-pneumatic.

20. The method of claim 15, wherein movement of the plate assembly is configured to apply traction to a portion of the cervical spine.
