How to choose prostheses made of different materials
Life is not easy, and accidents are inevitable. Prosthetic limb is a good equipment. For amputees, with the continuous progress of modern technology, it can restore the ability of self-care. In the process of choosing prosthesis, in order to ensure comfort, how to choose reasonably?
It is necessary to pay attention to the bearing cavity, which is an important connecting medium between the amputee's body and assistive devices. Generally, there are three kinds of manufacturing data of bearing cavity, which are casting resin, thermoplastic plate and carbon fiber bearing cavity. Different materials have different characteristics, which need to be combined with their own specific situation to make a reasonable choice.
Meanwhile, the common casting resin bearing cavity is characterized by high strength, light weight, long service life and is not affected by the climate. The defects are: disorderly process, high technical difficulty and high price. There's an allergy rate of one in ten thousand.
The characteristic of the bearing cavity of thermoplastic plate is that the inner bearing cavity is made of flexible plate, and then it has the characteristics of matching the muscle tension of the remnant limb when walking, which is comfortable to wear and easy to clean. The defects are: easily affected by temperature, climate, oxidation, deformation, short use cycle, only white.
The characteristics of carbon fiber bearing cavity are: high strength, high temperature resistance, not affected by temperature and climate deformation. Defects: high cost, expensive price, not wear-resistant, suitable for foot board. At present, domestic manufacturing is less.
