Silicone is a silica hydrate, belongs to a highly active non-crystalline state adsorbent material, compatibility, non-irritation of human tissue, non-toxic, with a good biological anaphylactic reaction, the body has very few rejection reactions; has good physicochemical properties and body fluids as well as tissues in contact with the process of maintaining its original elasticity and softness, is not degraded, it is a fairly stable inert material. It is a stable and inert substance. It can withstand high temperature and can be sterilized. Convenient processing and molding, easy to process the sculpture shape, easy to use. Make full use of this characteristic of silicone, will be used in the production of prostheses, with the material produced by the silicone sleeve has high strength and high flexibility, thermal stability, biological inertness and other characteristics. Upper limb silicone sleeve is designed for upper limb amputees to complete the suspension role of the product, due to direct contact with the patient silicone will release a silicone unique silicone oil, which can help the skin to maintain moisture and form a protective layer on the surface of the skin, play a role in protecting the skin is particularly suitable for patients with a large number of scars. At the same time, due to its high elasticity and flexibility can also play a stabilizing soft tissue, eliminating piston movement to provide more effective suspension function. Generally when making upper limb cosmetic hand not only need to consider is the appearance and weight, but also at the same time to consider whether the wearer is convenient, comfortable and so on. Traditionally, the suspension of the upper limb hand, especially the upper arm hand, is based on a strap, and the patient wears a prosthesis that wraps around the shoulder, thus restricting the movement of the shoulder joint and preventing shoulder lifting and forward and backward rotating movements. Only in this way can the prosthesis be stably suspended on the patient’s residual limb. The traditional forearm prosthesis is made of a soft resin that wraps around the elbow joint, limiting the angle of the elbow joint to suspend the prosthesis. The traditional suspension gives the patient less comfort in wearing the prosthesis. Now the introduction of silicone sleeve in the production of upper limb cosmetic hand not only changed the previous traditional way of hanging off and also changed the traditional acceptance of the cavity of the mouth so that the patient feels more convenient to wear, the prosthesis does not need to wrap the patient’s residual side of the shoulder or elbow in the production of a complete release of the shoulder or elbow so as not to affect the shoulder or elbow joint activities, in the summer wear can not be subjected to the limitations of the size of the collar, the healthy side of the armpit is not a result of the feeling of long-term backpack. It will not feel uncomfortable because of the long-term strap, and the adaptability is also quite good for the patients with burned limbs or residual limbs with scars. Due to the long-term wearing of the silicone sleeve, firstly, the silicone sleeve is highly flexible and elastic, which is comfortable for the patients to wear, and secondly, the silicone sleeve releases the silicone oil and thus promotes the healing of the skin. Maximizing the compensatory function of the upper limb prosthesis, the comfort is greatly improved at the same time the appearance is more natural and beautiful.
