"Weight bearing control" orthosis, abbreviated as WBC, is invested by the Ministry of health, health and labor of Japan, with Kawasaki Heavy Industry Co., Ltd. (in charge of Electronics), SMC Co., Ltd. (in charge of air pressure), Japan's Ministry of health, health and labor invested 16 billion yen; Takasaki prosthetic Co., Ltd. (in charge of prosthetic devices) and the Japanese National Center for rehabilitation of the disabled, which is responsible for clinical rehabilitation research, has been successfully developed. It combines electronics, sports medicine, orthopedics, rehabilitation and other disciplines, and has applied for patent licenses in Japan, the United States, Europe and China.

Typing

WBC can be divided into whole body type, whole simple type, inner pillar type and front type.

characteristic

The WBC walking device is different from the current walking equipment in that it has a variable plantar retraction device, and the waist changes little when walking. In addition, the fixture is highly rigid, and the weight from the support period to the swing period can move smoothly, and the energy consumption is less.

Structural composition

Pelvis and trunk supporting mechanism: the structure of this part is composed of thoracolumbar brace and long lower limb brace, and the hip joint (WBC limiter) is connected between the two thighs to further control the movement changes of the two thighs.

Plantar retraction device: the variable structure of the sole is composed of upper and lower parts. When the plantar is retracted and retracted, the signal of electronic device is combined to complete the driving change of plantar retraction.

Microcomputer system: it is composed of a microcomputer processed by an 8-digit CPU. The crutches are equipped with a control switch that can drive the plantar expansion and contraction, which can realize smooth walking. The further power source is liquid carbon dioxide, and the foot electronic system can control the consumption of gas.

Sensor: the sensor can detect the state of the front and rear positions of the left and right feet of the device.

Power source: in order to walk independently, the driving source is liquid carbon dioxide.

Stick: there is a switch on the walking stick that can control the change of plantar extension.

Evaluation of clinical trials

Evaluation of clinical trials: the four rehabilitation hospitals for the disabled in China are the National Rehabilitation Center for the disabled, Chidu hot spring hospital, Fushan Gaozhi hospital, and Hyogo Comprehensive Center for social welfare undertakings. Four patients with paraplegia of both lower extremities were involved in the clinical trial for three months. The results of the trial are realistic. 2. The results of the experiment can walk smoothly and walk continuously The walking cycle of more than 515m (action pressure 0.25mp) is 2.2-2.9s (walking rate is 41-45 steps / min), which is much better than the original goal.
