Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a flexor and extensor tendon trainer. Background Art

[0002] Extensor tendon injuries are mostly open, with more cuts being the most common, often accompanied by neurovascular injuries or bone and joint injuries, and closed lacerations may also occur. After the tendon ruptures, the corresponding joint loses its mobility. For example, if the superficial flexor tendon of the digitorum is ruptured, the proximal interphalangeal joint of the corresponding finger cannot flex; if the deep flexor tendon of the digitorum is ruptured, the distal interphalangeal joint cannot flex; if both the deep and superficial flexor tendons of the digitorum are ruptured, both the proximal and distal interphalangeal joints cannot flex. Since the intrinsic muscles of the hand are still intact, the flexion of the metacarpophalangeal joint is not affected. When the extensor tendons are ruptured at different locations, the corresponding joints cannot extend and may become deformed. Therefore, patients usually need to use rehabilitation training equipment for extensor tendon training.

[0003] Most of the flexor and extensor tendon trainers in the existing technology are relatively simple wearable structures. When used, most of the exercises require patients to actively perform flexion and extension activities. However, the patient's willingness to actively flex and extend activities is easily affected by psychological or physical discomfort, resulting in a low willingness for flexor and extensor tendon training, which can easily lead to tendon adhesion after extensor tendon repair surgery. For this reason, we propose a flexor and extensor tendon trainer. Utility Model Content

[0004] The main purpose of the present utility model is to provide a flexor and extensor tendon trainer, which is assembled at the palm and forearm. The palm shell of the flexor and extensor tendon trainer is supported by a reset spring at the forearm shell to bring the palm upward, so that the palm and forearm have passive upward movement. In order to lay the palm flat normally, the patient must press down the palm shell to compress the reset spring back to a position relatively horizontal with the forearm shell, thereby realizing the patient's passive flexion and extension movement, effectively reducing tendon adhesion after extensor tendon repair surgery, and helping patients with flexor and extensor tendon injuries to quickly and conveniently complete the recovery of hand function after surgery, which can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a flexion and extension tendon trainer, characterized in that: it includes a palm shell, two return springs and a forearm shell, the two sides of the palm shell are respectively connected to one end of the two return springs, and the two sides of the forearm shell are respectively connected to the other end of the two return springs, the shell of the palm shell is provided with an integrally formed thumb shell, the outer side of the thumb shell is provided with a first Velcro block and a first Velcro strap used in conjunction with the first Velcro block, the outer side of the palm shell is provided with a second Velcro block and a second Velcro strap used in conjunction with the second Velcro block, and the outer side of the forearm shell is provided with a third Velcro block and a third Velcro strap used in conjunction with the third Velcro block.

[0006] Preferably, both ends of the return spring are fixed to the outside of the palm shell and the forearm shell by rivets.

[0007] Preferably, the inner surfaces of the thumb shell and the forearm shell are arc-shaped surfaces.

[0008] Preferably, the inner surface of the palm shell is an arc-shaped surface.

[0009] Preferably, the two return springs are symmetrically arranged on both sides of the palm shell and the forearm shell.

[0010] Preferably, the third Velcro blocks and the third Velcro tapes are provided in two groups.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This utility model utilizes a flexor and extensor tendon trainer assembled at the palm and forearm. The palm shell of the flexor and extensor tendon trainer is supported by a return spring at the forearm shell, pulling the palm upward, allowing the palm and forearm to passively move upward. To keep the palm flat, the patient must press down on the palm shell to compress the return spring back to a position relatively horizontal with the forearm shell, thereby enabling the patient's passive flexion and extension movement. This effectively reduces tendon adhesions after extensor tendon repair surgery and helps patients with flexor and extensor tendon injuries quickly and conveniently recover hand function after surgery. The utility model has a simple structure and is easy for patients to put on and take off. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0017] like Figure 1-2As shown, a flexor and extension tendon trainer includes a palm shell 1, two return springs 7, and a forearm shell 8. The two sides of the palm shell 1 are respectively connected to one end of the two return springs 7, and the two sides of the forearm shell 8 are respectively connected to the other ends of the two return springs 7. The two return springs 7 are symmetrically arranged on both sides of the palm shell 1 and the forearm shell 8. The shell of the palm shell 1 is provided with an integrally formed thumb shell 2, and the outer side of the thumb shell 2 is provided with a first Velcro block 3 and a first Velcro strap 4 for use with the first Velcro block. The outer side of the palm shell 1 is provided with a second Velcro block 5 and a second Velcro strap 6 for use with the second Velcro block 5. The outer side of the forearm shell 8 is provided with a third Velcro block 10 and a third Velcro strap 11 for use with the third Velcro block 10. The third Velcro block 10 and the third Velcro strap 11 are provided in two groups.

[0018] like Figure 1-2 As shown, the two ends of the return spring 7 are fixed to the outside of the palm shell 1 and the forearm shell 8 by rivets 9. The inner surfaces of the thumb shell 2 and the forearm shell 8 are arc-shaped surfaces. The inner surface of the palm shell 1 is also an arc-shaped surface.

[0019] like Figure 1-2 As shown, the practical method of the present invention is as follows: the present invention is a flexor and extensor tendon trainer, and the patient puts the palm facing downward into the palm shell 1, and puts the thumb into the thumb shell 2, and the arm is stuck in the forearm shell 8. Then use the first Velcro strap 4 to wrap around the thumb and adhere to the first Velcro block 3 to fix the thumb. The second Velcro strap 6 wraps around the back of the hand and adheres to the second Velcro block 5 to fix the back of the hand. The third Velcro strap 11 wraps around the arm and adheres to the third Velcro block 10 to fix the arm. Then the flexor and extensor tendon trainer completes the assembly at the palm and forearm, and under the elastic support of the reset spring 7, when the forearm shell 8 is flat, the palm shell 1 is supported by the reset spring 7 and slightly lifted up with the palm, so that the palm and forearm have passive upward movement. In order to lay the palm flat normally, the patient must press down the palm shell 1 to compress the return spring 7 back to a position relatively horizontal with the forearm shell 8, thereby enabling the patient's passive flexion and extension movement, reducing tendon adhesion after extensor tendon repair surgery, and helping patients with extensor and flexor tendon injuries to quickly and conveniently complete hand function recovery after surgery, with good results. The patient can use the exerciser very conveniently. Simply pull out the first Velcro strap 4, the second Velcro strap 6, and the Velcro wrap C11 from the first Velcro block 3, the second Velcro block 5, and the third Velcro strap 11 to remove the flexor and extensor tendon exerciser from the palm and forearm.
