Description

Independently adjust tensile knee joint rehabilitation training ware

Technical Field

The invention relates to the field of medical instruments, in particular to an automatic adjusting and stretching knee joint rehabilitation trainer.

Background

The structure of the knee joint is the most complex pulley joint in all joints, especially the joint bears great lever force in the stretching and bending activities, because the knee joint bears most weight from the human body, and because of the large range of motion, the structure makes the knee joint bear larger impact and pressure than the hip joint and the ankle joint, which is one of the most worn parts of the human body and the earliest aged part, and the knee joint is one of the most stiff joints after trauma.

In the later stage of recovery from knee joint injury, in order to ensure normal interaction after knee joint, leg bending training needs to be carried out so as to ensure free movement of the knee joint in the later stage, Chinese patent publication No. CN209933410U discloses a knee joint rehabilitation device, CN209450876U discloses a knee joint rehabilitation training device, which are all the devices, but have a problem of being similar to the existing devices, namely, when training is carried out, a patient needs to bend automatically through leg strength, but the recovery conditions of the patient are different, the patient often needs help of other people to use, the adjusting mode is too inflexible, and the adaptability of the device in use is further reduced mainly by depending on the return mode of a spring.
