Problems solved by technology

In the development of joint surgery for more than 40 years, it has played a very important role. However, with the advancement of the concept and technology of joint surgery, experts have found that electric CPM is easy to cause knee joint pain, swelling and intra-articular hemorrhage and other factors, which will seriously Affect postoperative rehabilitation and joint function recovery, not suitable for early functional exercise after knee replacement
Some experts advocate the use of bare hands for knee flexion and extension exercises, but the purpose is not strong, and the patient is not active in the exercise due to postoperative pain, trauma, and a long time for knee bandaging.

Embodiment 3

[0036] Case 1: Yu Xzhen, female, 67 years old, hospital number 227168, a retired employee of a hospital in Guangxi, was admitted to the hospital due to repeated pain in the right knee joint and limited mobility. On October 18, 2010, the right knee replacement was performed under general anesthesia. On the basis of routine treatment and nursing, artificial CPM was used to perform knee joint flexion and extension exercises. He was cured and discharged 14 days after the operation. The knee joint HSS score was 45 points before operation, and the HSS score was 85 points before discharge. The operation effect was satisfactory.

[0037] Case 2: Lei Xhua, female, 75 years old, a retired employee of a certain railway hospital in Guangxi, hospital number 346688, was admitted to the hospital due to recurrent bilateral knee joint pain and limited mobility. On October 20, 2010, the right knee replacement was performed under general anesthesia. On the basis of routine treatment and nursing ...

Abstract

The invention discloses a manual lower limb passive motion device. The manual lower limb passive motion device comprises a base, a movable type pedal, aluminum alloy rails and pulleys. The aluminum alloy rails are fixedly mounted on the base, and the pulleys are fixedly mounted on the lower portion of the movable type pedal and are embedded into the aluminum alloy rails. The manual lower limb passive motion device can be used for functional training of a patient after knee-joint displacement surgery, the advantages of an electric CPM and the advantages of unarmed functional training are integrated, the functional training enthusiasm of the patient is fully aroused, on the basis that self-control can be achieved, a joint bending and stretching exercise is carried out, meanwhile, the operation method is safe and simple, functional training time is flexible, and the device is economical and practical.

Description

technical field [0001] The invention relates to the technical field of joint rehabilitation medical devices, in particular to an artificial lower limb passive mover. Background technique [0002] With the improvement of people's living standards, the prolongation of life expectancy and the gradual increase in the proportion of elderly people, the replacement rate of knee joints is bound to increase. After knee replacement, the main clinical manifestations are pain and limited flexion and extension of the knee joint, and the degree of flexion and extension of the knee joint directly reflects the effect of the operation. At present, some clinical experts advocate the use of electric lower limb mobilizers (electric CPM) for flexion exercises after surgery. Electric CPM gradually "softens" the sticky and stiff knee joint through reciprocating, multiple, and continuous passive flexion and extension, and finally reaches a normal range of motion. In the development of joint surge...
