Description

A special protective gear with adjustable angle after knee joint surgery

Technical Field

The utility model relates to the field of protective gear, and more specifically, to a special protective gear with adjustable angle after knee joint surgery.

Background Art

The knee joint is composed of the lower end of the femur, the upper end of the tibia and the patella. It is the largest and most complex joint in the human body and belongs to the trochlear joint. The patella is connected to the patellar surface of the femur, and the medial and lateral condyles of the femur are opposite to the medial and lateral condyles of the tibia respectively. The synovial layer of the knee joint is the widest and most complex joint in the whole body. It is attached to the periphery of the articular surface of each bone in the joint and covers all structures in the joint except articular cartilage and meniscus. The surgeon needs to reasonably handle the bone defect, accurately place the prosthesis and establish a firm bone-prosthesis contact interface to provide sufficient support for the prosthesis and obtain satisfactory surgical results. Publication No. (CN214231853U) describes a special protective gear with adjustable angle after knee surgery. When the operator is rehabilitating the knee joint, the burden on the knee joint can be relieved, thereby assisting the operator in performing rehabilitation movements and preventing the exercise from causing excessive burden on the knee joint and causing damage to the knee joint. The elastic strap can be wrapped around the thigh arm guard, and in conjunction with Velcro, the operator's leg can be tied under the silicone pad, so that the silicone pad is wrapped around the operator's knee joint, thereby fixing and protecting the knee joint.

It was found that the above-mentioned device, when used, can facilitate postoperative rehabilitation training for patients and avoid excessive burden on the knee joint. However, the above-mentioned device cannot fix the angle of the protective gear according to the comfort of the patient's leg angle after the patient is tired from rehabilitation exercises, and it is more laborious to use for a long time.
