Problems solved by technology

[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

Embodiment 1

[0025] Such as figure 1 , figure 2 , image 3 with Figure 4 Shown, a kind of rehabilitation orthosis of finger flexor tendon rupture, comprises clockwork elastic trainer and dorsum of hand protection orthosis, and described clockwork elastic trainer is arranged on the palm surface 16, and described back of hand protection orthosis is arranged on the back of hand 17 Above, the clockwork elastic trainer includes a fingertip fixing belt 1, a fixing belt 2, a tension positioning button 3, a traction string 7, a wrist belt 9 and a power device, and the fingertip fixing belt 1 is fixed on the fingertip , the traction string 7 passes through the tension positioning button 3, the tension positioning knob 3 is used to limit the traction string 7, one end of the traction string 7 is connected with the fingertip fixing belt 1, The other end is connected with the power device, the wrist strap 9 is connected with the power device, the wrist strap 9 is set on the arm with the power dev...

Embodiment 2

[0030] The main feature of this embodiment 2 is that: the fixed strap 2 is set on the palm, and cooperates with the hook surface 13 of the finger Velcro or the hook surface 14 of the palm Velcro. All the other features are with embodiment 1.

[0031] The principle of this embodiment 1 and 2: use the combination of limitation and power to carry out rehabilitation training after finger flexor tendon repair, use plastic splints to provide daily protection and joint angle limitation during training, use power springs to provide unidirectional flexion power, Minimize the tension of the damaged tissue and minimize the risk; the direction of the traction string is always in line with the original functional state of the finger, and the power spring box can be adjusted according to the specific conditions of the patient; the power spring is used to provide power, and the tension is easy to adjust. The operation is simple; the pull force positioning button is used to provide the pull f...

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...
