The application of silicone cover in upper extremities cosmetic hands

Silicone is a kind of silicon dioxide compound, which belongs to a kind of highly active non-crystalline state adsorption material. It is compatible, non-irritating to human tissues, non-toxic, has good biological non-allergic reactions, and has very few body rejection reactions; It has good physical and chemical properties and can maintain its original elasticity and softness during contact with body fluids and tissues without being degraded. It is a fairly stable inert substance. It can withstand high temperature and can be sterilized. It is easy to process and shape, easy to process and engrave shape, and easy to use.Make full use of the characteristics of silica gel and use it in the production of prostheses. The silicone sleeve made of this material has the characteristics of high strength, high flexibility, thermal stability, and biological inertness.

Upper extremity silicone sleeve is a product designed and made for upper extremity amputees to complete the suspension function. Direct contact with the patient will release a silicone oil unique to silicone, which can help the skin maintain moisture and form protection on the skin surface The layer protects the skin and is especially suitable for patients with a large number of scars. At the same time, due to its high elasticity and flexibility, it can also stabilize the soft tissue, eliminate piston movement and provide a more effective suspension function.

Generally, not only the appearance and weight need to be considered when making upper limb beauty hands, but also whether it is convenient and comfortable to wear. Traditional upper-limb cosmetic hands, especially upper-arm cosmetic hands, are mainly suspended by straps, and the prosthesis worn by the patient must wrap the shoulders to limit the movement of the shoulder joints, and cannot perform shoulder lifting and pronation and supination. In this way, the prosthesis is stably suspended on the patient's residual limb. In the traditional forearm prosthesis, the position of the elbow joint is wrapped by soft resin, and the prosthesis is suspended by restricting the angular position of the elbow joint. The comfort of the traditional suspension for the patient to wear the prosthesis is slightly worse.

The introduction of silicone sleeves in the production of upper limb beauty hands not only changes the previous traditional suspension style, but also changes the mouth shape of the traditional receiving cavity at the same time, so that the patient feels more convenient to wear, and the prosthesis does not need to cover the patient’s The stump of the shoulder or elbow, completely release the shoulder or elbow so as not to affect the movement of the shoulder or elbow joint. It can be worn in summer without being restricted by the size of the collar, and the uninvolved armpit will not be affected by the long-term sling It feels uncomfortable. For patients with burns or scars on the residual limbs, the adaptability is also quite good. Due to long-term wearing of silicone sleeves, the first is the high flexibility and elasticity of the silicone sleeve, and the patient is comfortable to wear. The sleeve will release silicone oil to promote skin healing. The compensation function of the upper limb prosthesis is maximized, and the comfort is greatly improved, and the appearance is more natural and beautiful.
