Rehabilitation orthosis for rupture of finger flexor tendon

Abstract

The invention relates to a rehabilitation orthosis for rupture of finger flexor tendon, and belongs to the technical field of medical machinery. The device comprises a spring elasticity training device and a hand back protection orthosis, wherein the spring elasticity training device is arranged on the surface of the palm, and the hand back protection orthosis is arranged on the surface of the hand back. The spring elasticity training device comprises a fingertip fixing band, a fixing binding band, a tension positioning button, a pulling string, a wrist binding band, and a power device, the tension positioning button is used for limiting the pulling string, the power device comprises a knob, a power spring, a concentric shaft, and a power spring box, the power spring drives the pulling string to move, the hand back protection orthosis is formed by a hand back plate and a forearm back plate, and an included angle of 120 degrees to 180 degrees is arranged between the hand back plate and the forearm back plate. The rehabilitation orthosis is mainly used for the treatment of postoperative rehabilitation of the tendon rupture repair, effects of adhesion prevention, healing promotion, improvement of the healing quality, and the improvement of the hand function are achieved, the novel adjustment is convenient and simple, the comfort is high, and the effect of rehabilitation training is good.

Description

technical field [0001] The invention relates to a rehabilitation orthosis, in particular to a rehabilitation orthosis for finger flexor tendon rupture, which belongs to the technical field of medical machinery. Background technique [0002] At present, the flexor tendon of the finger plays a major role in the gripping function of the hand. Its anatomical structure is relatively special, which is suitable for its physiological function. Therefore, the repair of the flexor tendon has its own particularity. group, starting from the forearm, passing through the carpal tunnel, the center of the palm, and the tendon sheath tube of the fingers, and reaching the base of the distal phalanx and the crest of the proximal part of the middle phalanx respectively. The whole tendon is surrounded by loose connective tissue, which not only nourishes the tendon, but also facilitates the tendon Among them, sliding is called peritendon or peritendon tissue, and the current rehabilitation orthos...

[0002] At present, the flexor tendon of the finger plays a major role in the gripping function of the hand. Its anatomical structure is relatively special, which is suitable for its physiological function. Therefore, the repair of the flexor tendon has its own particularity. group, starting from the forearm, passing through the carpal tunnel, the center of the palm, and the tendon sheath tube of the fingers, and reaching the base of the distal phalanx and the crest of the proximal part of the middle phalanx respectively. The whole tendon is surrounded by loose connective tissue, which not only nourishes the tendon, but also facilitates the tendon Among them, sliding is called peritendon or peritendon tissue, and the current rehabilitation orthosis for finger flexor tendon rupture has the following problems: 1) The fixation and restriction structure is more complicated, and active activities are less allowed; 2) It does not play a role in the range of motion. Effective restriction and protection, early rehabilitation training is likely to lead to the risk of re-rupture; 3) The direction of finger movement cannot be clearly defined, and there is no channel to effectively fix the direction of finger movement, which may easily lead to the risk of re-rupture of the repair tendon
