What should be paid attention to when choosing prosthesis leg for home use?
1. According to the condition of the stump, we should choose the proper method of the socket and prosthesis leg for home use suspension. We should not blindly pursue the suction type receiving cavity: the stump is too short; the patients with too much subcutaneous soft tissue and poor venous reflux are not suitable for the use of the suction type prosthesis leg for home use. If forced to use, it will often fall off or cause soft tissue swelling at the end of the stump.
2. Choose the function and material of knee joint correctly according to the age and walking needs. Don't blindly pursue high price and import artificial limb parts. The elderly and the weak should choose light prosthetic parts, and they need reliable stability in walking. In order to prevent the prosthetic limb from breaking down suddenly and falling down, the knee joint with hand lock or the knee joint with load-bearing self-locking should be selected; the skeletal thigh prosthesis should be selected for children due to the needs of growth and development, so as to extend the prosthesis every year; the thigh prosthesis with knee joint with step frequency tracking performance can automatically adjust the leg swing speed according to the walking speed, but these knee joints are heavy, They are all imported parts with high price. They are mainly suitable for young people who need to walk fast. By the way, I would like to remind the thigh amputees that you should have a clear understanding of what kind of knee joint you have installed, the functional characteristics it should have, and whether it has already been used.
3. According to the body weight, choose the appropriate back buffer spring of artificial foot or uniaxial ankle joint (mostly made of rubber): the small weight should choose the soft heel of the fixed ankle soft heel or the soft rear buffer spring of the uniaxial ankle, otherwise it will easily lead to sudden leg weakness in walking and the toe swing when the heel lands.
4. Pay attention to the influence of the surrounding environment on the use of the thigh prosthesis: the current thigh prosthesis can help amputees walk on flat roads, climb and descend stairs, and go up and down slopes that are not too steep. It is difficult to go up and down steep slopes to wear thigh prosthesis. Therefore, most people who live in mountainous areas prefer to use strong crutches instead of artificial limbs.
The early installation of prosthesis after amputation is conducive to the reconstruction of sensory innervation and nerve feedback, prevention of muscle atrophy and joint contracture deformity, so that the residual limb can restore its previous function, expand the activity space, continuously increase physical fitness, and recover the body integrity of patients as soon as possible, which is conducive to restoring confidence and stimulating disease resistance. According to the statistical data of tens of thousands of prosthetics, whether it is trauma or swelling The earlier the prosthesis is is installed after amputation, the better the rehabilitation.
Several principles of prosthesis assembly are as follows
1、 The prosthetic technique should be selected and determined according to the condition of the stump and the physical condition of the patient (such as the length of the stump, muscle strength, range of motion of the joint, soft tissue and scar).
2、 We should fully consider the patient's age, working environment, living environment and psychological work requirements to determine the form and type of prosthesis.
3、 According to the patient's economic ability and current payment ability, the price grade of prosthetic limb is selected.
4、 The treatment, nursing and muscle strength training of the stump are necessary before the prosthesis is is installed.
5、 The training and adjustment of prosthesis is an important link to ensure the functional gait of patients.
6、 In the use of prosthetic limb, the assembly unit should carry out regular repair and maintenance.
7、 The quality inspection of prosthetic limb must be carried out by the prosthetic professional manufacturer assessed by the state
