Problems solved by technology

[0003] Although the exoskeleton developed abroad is advanced in technology and powerful in function, it is expensive, complicated to operate, confidential in technology, and not conducive to promotion. Many patients do not have the conditions to train
In actual treatment, most paraplegic patients and polio patients have to wear old-fashioned and traditional orthotics for walking training. Because traditional orthotics mainly play a fixed role, the knee and ankle joints must be fixed. When walking, the knee joints are always in the Stretch and fix the state, and then rely on the strength of the patient's abdominal muscles, lumbar back muscles and iliopsoas muscles to swing the hips to drive the swing of the entire lower limbs. Such an abnormal gait has little effect on the recovery of the strength of the key muscles of the lower limbs. It has little effect on enhancing the plasticity of neurons and reconstructing the walking function of patients, and it also increases the cardiopulmonary load of patients during walking

Embodiment 1

[0049] Embodiment 1, knee joint hinge

[0050] The knee joint hinge of the present invention comprises the following components:

[0051] Lower hinge body 1, claw 2, tooth hinge body 3, fixed shaft 4, rivet pin 5, lock shaft 6, pull rod shaft 7, lock pin 8, pull rod 9, spring 10, retaining ring 11.

[0052] In the knee joint hinge, the connection relationship of each component is as follows:

[0053] The toothed hinge body 3 passes through the fixed shaft 4 and is installed on the knee joint hinge. The claw 2 is arranged under the toothed hinge body 3. One end of the pull rod 9 passes through the pull rod shaft 7 and is installed on the claw 2. The other end of the pull rod 9 is connected to the pull wire 16. A lock pin 8 with a lock shaft 6 is provided in the middle of the claw 2. By turning the lock pin 8, the claw 2 can realize three different functions, that is, full lock, no lock, and knee-ankle linkage unlocking.

[0054] Wherein, a spring 10 and a retaining ring 11 ar...

Embodiment 2

[0055] Embodiment 2, the orthosis of knee joint hinge of the present invention

[0056] The orthosis of the present invention comprises the following parts: knee joint hinge 12, calf brace 13, ankle hinge 14, pedal 15, backguy 16, calf hoop 17, thigh hoop 18 and thigh brace 19;

[0057] The connection relation of described each parts is as follows: thigh support bar 19 and calf support bar 13 are respectively fixedly installed on thigh hoop 18 and calf hoop 17, and thigh support bar 19 and calf support bar 13 are connected together by knee joint hinge 12, and calf The lower end of support bar 13 connects pedal 15, and the heel portion of pedal 15 is provided with a backguy 16, and the top of backguy 16 connects the pull bar 9 on the knee joint hinge 12, and ankle joint hinge 14 is housed on the calf support bar 13.

Embodiment 3

[0058] Embodiment 3, the using method of orthosis of the present invention

[0059] Combine now figure 1 and figure 2 Illustrate the use method of the present invention:

[0060] Knee-ankle linkage unlocking mode (turn lock pin 8 to adjust to knee-ankle linkage unlocking mode)

[0061] 1. Adjust the tightness of the cable through the swing distance of the lower limb on the side of the orthosis to control the unlocking angle of the knee joint;

[0062] 2. The patient wears the lower limb orthosis;

[0063] 3. After the patient steps out of the contralateral leg (the leg not wearing the orthosis), the center of gravity gradually shifts to the orthosis side leg (the leg wearing the orthosis) during the support period of the lower limb on the orthosis side;

[0064] 4. Through the forward transfer of the center of gravity on the side of the orthosis, when the center of gravity is transferred to the front of the sole of the foot, the ankle joint is dorsiflexed, triggering the ...

Abstract

The invention belongs to the field of medical appliances, and relates to a novel knee-joint hinge of a standing period control orthosis for rehabilitation, in particular to the knee-joint hinge of the orthosis, which can be used for walking function training and walking function compensation of patients with lower limb paralysis such as spinal cord injury, infantile paralysis and the like, and can keep a certain physiological gait.

Description

Technical field: [0001] The invention belongs to the field of medical equipment, and relates to a new type of knee joint hinge for stance control orthosis for rehabilitation, specifically a knee joint hinge that can be used for walking function training and compensating walking function for patients with spinal cord injury, polio and other paralyzed lower limbs. , and can maintain a certain physiological gait orthosis knee hinge. Background technique: [0002] Paralyzed patients with spinal cord injury and poliomyelitis often have walking dysfunction due to the paralysis of key muscles of the lower limbs. At present, there are few ways to restore normal walking function of patients with spinal cord injury and poliomyelitis. Walking function training is a very effective way. Methods: In animal experiments, it was found that normal physiological walking training can selectively increase motor neural pathways, increase the coordination of motor pools, activate a small number of...
