A flexible cable-driven parallel cervical spine rehabilitation device

Abstract

The invention discloses a flexible rope driven parallel connection cervical vertebra rehabilitation device. The device is used for solving the problems that the degree of freedom is low, the patient rehabilitative effect is poor, no sensor detection exists, and control precision is low. The device comprises a first movable winding mechanism, a second movable winding mechanism, a third movable winding mechanism, a fourth movable winding mechanism, a support and a rope rehabilitation mechanism. The first movable winding mechanism, the second movable winding mechanism, the third movable winding mechanism and the fourth movable winding mechanism are of the identical structure. The first movable winding mechanism and the fourth movable winding mechanism are symmetrically arranged on two third cross beams of the same structure at the bottom end of the support. The second movable winding mechanism and the third movable winding mechanism are arranged on a first cross beam on the top of the support. The rope rehabilitation mechanism is arranged in the middle of the support. One ends of four steel wire ropes in the rope rehabilitation mechanism are sequentially connected with the first movable winding mechanism, the second movable winding mechanism, the third movable winding mechanism and the fourth movable winding mechanism. The other ends of the four steel wire ropes are sequentially connected with four hanging rings of the same structure on a neck belt of the rope rehabilitation mechanism.

Description

technical field [0001] The invention relates to a rehabilitation medical device, more precisely, the invention relates to a cable-driven parallel cervical spine rehabilitation device. Background technique [0002] Cervical spondylosis is a functional degenerative disease. When the cervical spine maintains a fixed position for a long time, due to lack of exercise, the neck muscles and ligaments will degenerate, resulting in intervertebral disc prolapse and ligament thickening, resulting in compression of the cervical spinal cord, nerves or vertebral arteries. A clinical syndrome that produces a spectrum of dysfunction. For a long time, cervical spondylosis has long been a common disease among middle-aged and elderly people clinically, and it also occurs from time to time among young people. At present, the equipment for cervical spine rehabilitation mainly makes the patient's cervical spine perform a single-degree-of-freedom traction movement, which has low precision and ave...
