Description

A kind of auxiliary exercise device after knee joint replacement

technical field

The invention belongs to the technical field of orthopedic medical devices, and more particularly relates to an auxiliary exercise device after knee replacement and its usage method.

Background technique

Artificial knee replacement surgery has gradually become a mature solution to knee osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis. The operation process is not complicated. For doctors, the operation itself is very important to the effect of artificial knee replacement. For patients, it is especially important to actively cooperate with rehabilitation treatment and active rehabilitation exercises after surgery. . Therefore, functional rehabilitation exercises should be carried out early after surgery, otherwise it will lead to knee joint dysfunction and seriously affect the effect of surgical treatment. Continue to maintain long-term exercise even after reaching normal levels.

The electric knee exerciser (CPM) available on the market is often damaged due to the patient's active knee resistance. Reasonable setting of exercise will make the patient take an uncooperative attitude because of the unbearable pain, so that a good recovery effect cannot be achieved.

In addition, rehabilitation training should be carried out according to the actual situation of the patient, and the intensity, time, and method of exercise should be adjusted in a timely manner according to the needs of different rehabilitation stages and functional recovery, and exercises that increase the range of motion of the knee joint and increase muscle strength should be combined.

Some of the current postoperative auxiliary exercise devices for the knee joint are expensive, bulky, and bulky, and most patients have no intention of purchasing them personally, which cannot meet the needs of the masses; some have single functions and are not suitable for the training needs of different rehabilitation stages. And most of the rehabilitation equipment is for the corresponding passive exercise therapy for the knee joint and related muscle groups, and there are few rehabilitation equipment related to active exercises. In addition, there is no knee joint rehabilitation device suitable for home use on the market.

The present invention improves the existing rehabilitation equipment, and provides an economical, practical, popular, active exercise, and an auxiliary exercise device after knee replacement surgery that meets the training needs of different rehabilitation stages.
