Description
Technical field
The present invention relates to knee joint rehabilitation device field more particularly to a kind of sideization knee articulation degree training devices.
Background technique
With the aggravation of aging process, more and more the elderlys face the puzzlement of orthopaedic disease, and wherein knee joint moves back
Row osteoarthropathy is the serious diseases such as the common disease of the elderly, such as knee joint characteristic of stock arthritis, rheumatoid arthritis,
Since knee joint is the important weight-bearing joints of lower limb, structure and function is most complicated person in human synovial, is directly affected normal
Quality of life causes great pain to patient, so the patient for needing to carry out total knee replacement is more and more.Pass through knee
Joint replacement replaces the knee joint of damage with the artificial knee joint with bio-imitability energy, can release gonalgia, improves knee
Function of joint is corrected deformity of knee and is obtained steadily in the long term, improves patients ' life quality, be current clinical treatment knee joint disease
The effective means of disease.
It is postoperative to carry out artificial knee joint, to make patient obtain higher Quality of rehabilitation, rehabilitation is carried out to patient in time and controlled
It treats, prevents synarthrophysis, influence knee articulation degree.There is CPM joint of lower extremity health in improving patient articular's mobility health scheme
It answers a pager's call, fix bicycle, independently bend and stretch exercise etc., but above-mentioned instrument and treatment method at least exist in the training of knee articulation degree
Following problems: (1) kneed angle of bending and stretching is to stretch 5 °~10 ° upwards using thigh extended line as baseline, 120 ° in the wrong downwards~
150 °, since postoperative pain, swelling bring are inconvenient, when passive exercise, many patients were to swing to drive shank with thigh hip joint
Knee joint is bent and stretched, although shank swing angle can reach requirement, actual knee joint bending and stretching using thigh extended line as baseline
Angle is smaller than swing angle, and exercise is not achieved and requires, exercise effect is not significant.(2) Normal Knee mobility stretch 5 °~
10 °, bend 120 °~150 °, in rehabilitation in first day after surgery can small range bend the knee 20 °, daily to increase by 10 °~15 °, third day can
40 °~60 ° are increased to, has high requirement to the active and passive angle of bending and stretching of postoperative ankle, angle too small rehabilitation efficacy is unknown
Aobvious, excessive easily cause of angle is pulled, but many instruments and gimmick not can display real-time or control forging in actual measure of rehabilitation
The angle that artificial knee joint is bent and stretched when refining can not give patient's reference standard, be unfavorable for taking exercise and implement, while patient is in passive exercise
In can not according to the personal timely stopped taking exercises of tolerable pain situation, exist excessively bend and stretch caused by damage risk.(3) rehabilitation early stage
When, patient cannot walk with descending, inconvenient initiative exercise, and when by instrument passive exercise, biggish instrument is mobile inconvenient, by bed
Change reconditioning to be restricted, is unfavorable for patient's use.
Therefore it is badly in need of a kind of sideization knee articulation degree training device, hip joint is swung when overcoming exercise, knee is driven to close
Section bends and stretches that angle is not up to standard, cannot observe in real time and control knee joint and bend and stretch angle and inconvenient for use be unfavorable for asking for bed sideization
Topic.
