Description

Rehabilitation training device used after knee joint replacement operation

Technical Field

The utility model belongs to the technical field of orthopedic rehabilitation auxiliary devices, and particularly relates to a rehabilitation training device used after knee joint replacement.

Background

At present, the rehabilitation training modes for the knee joint operation of patients in clinic mainly comprise three modes: 1. the knee joint continuous passive movement instrument is adopted to assist the knee joint passive movement; 2. assisting the patient to perform rehabilitation training by a rehabilitation engineer or family members; 3. the patient performs rehabilitation training by himself. However, these three approaches all suffer from certain drawbacks:

the knee joint continuous passive movement instrument is adopted to assist the passive movement of the knee joint: the knee joint continuous passive activity instrument with the existing structure can only provide rigid and passive rehabilitation training for patients, and the patient has more bending movement times and long duration time when performing rehabilitation training, so that discomfort is easy to appear for the patients, the knee joint of the patient is seriously swollen, and secondary injury is caused to the knee joint of the patient;

meanwhile, the requirement of muscle strength training of lower limbs of a patient cannot be met by utilizing passive movement of an instrument, the muscle strength training of the patient is insufficient, a reversing condition possibly occurs after discharge, and the rehabilitation training effect is poor, such as (a rehabilitation device after full knee joint replacement operation of Chinese patent CN 113786312A);

furthermore, the knee joint continuous passive exercise apparatus is expensive, only special hospitals can be correspondingly equipped, and the knee joint continuous passive exercise apparatus is not suitable for patients to purchase and use by themselves. Therefore, this approach can only be performed during hospitalization and cannot be continued for rehabilitation training after discharge of the patient.

The rehabilitation training mode is that a rehabilitation engineer or family members assist patients to perform rehabilitation training: firstly, the rehabilitation engineer or family member manual assistance training is low in efficiency, and is not developed for a long time in a large range; secondly, the pain of the patient cannot be perceived in real time during rehabilitation training, and the cooperative coordination of the pain and the pain is difficult; furthermore, the normalization of each knee flexion motion of the patient is not guaranteed: according to different patient conditions, the medical advice is followed to meet the requirement of a certain angle at a certain stage, the exercise angle can only be estimated when the rehabilitation training is assisted, the effect of each rehabilitation training, namely the buckling angle, can not be mastered timely and accurately, and the rehabilitation training effect is not ideal.

The patient carries out rehabilitation training by oneself: the patient can only assist knee joint buckling or suffering limb self-buckling exercise through both hands, and because the knee bending angle can not be mastered in time, individual difference can appear: obvious pain is caused in the rehabilitation training process, or the situation that the knee bending angle is not in place and the knee bending angle is excessive due to poor angle mastering is caused.

Meanwhile, the thighs and the shanks of people are not in the same straight line, the leg types of different patients are different, and the prior training device for wrapping the legs does not consider the point, so that the skin is easy to abrade.

In order to solve the above problems, a rehabilitation training device for use after knee joint replacement is proposed herein.
