Abstract

The present invention discloses an internal extension-aid spring hydraulic buffer knee joint hinge, it can be mounted in the knee joint position of knee, ankle and foot orthopedic device, and is formed from oil cylinder, extension-aid spring and connecting support device. The described oil cylinder is mounted in the back of knee, ankle and foot orthopedic device, and the oil cylinder is connected with top bar, in the oil cylinder the bottom end of said top bar is equipped with extension-aid spring, and on the oil cylinder an oil drain hole is set. The described connecting support device is respectively placed on two sides of said knee, ankle and foot orthopedic device. Said invention can utilize internal mounted spring and hydraulic cylinder to provide buffer action when the paraplegic patient stands up or siet down.

Description

technical field [0001] The invention relates to a walking device for paraplegics, in particular to a knee joint hinge with internal extension-assisted spring hydraulic buffering. Background technique [0002] In order to be able to return to society and enjoy life again, paraplegic patients often need to use paraplegic walking devices. The paraplegic walking device consists of knee-ankle-foot orthosis, knee hinges and interactive hinges, which are assembled on the paraplegic lower limbs of the patient to help the patient stand and walk. The patient is worn on both lower extremities and walks with a walker and crutches. But the knee joint hinge of the existing paraplegic walker is a simple locking structure, which only has a locking effect on the knee joint, lacks cushioning when sitting down, and stretching function when standing. It is inconvenient to wear and sit, and has poor safety. It is extremely difficult and unsafe for patients to stand up and sit down. Contents ...
