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, andwherein 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.

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.

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. - View Dependent Claims (9, 10, 11, 12, 13, 14)

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. - View Dependent Claims (16, 17, 18, 19, 20)
