What is silica gel? What are the advantages and disadvantages of silica gel liner? What kind of people need to wear silicone liner? What type of silicone liner is available on the market? Many friends who use prosthetic limbs do not know much about products like silicone liner, especially patients who wear prosthetic limbs.
Since the 1970s, silica gel as a kind of medical material, the medical community recognized that silica gel itself to the human body is non-toxic, no irritation, no allergic reaction of a material, even if some users have allergic symptoms, most of the silicone liner is caused by some fillers.
The application of silicone liner in the prosthesis industry is also relatively common: for example, the initial prosthetic socket of the lower leg is supported by the patellar ligament, and the internal and external condyles and patella are suspended, and the prosthetic socket with concentrated stress points is gradually transformed into the prosthetic socket in the form of TSB (total surface bearing). The popularity of the prosthetic socket in the form of TSB has also greatly promoted the application of silicone liners in prosthetics. The touch of silicone feels like jelly. The human body is divided into pressure resistant parts and non-pressure resistant parts, which is also the basic knowledge when making prosthetic socket.
Pressure resistant areas (such as large diaphysis, muscles such as the tibialis anterior muscle, etc.) where pressure modification is not harmful to the human body.
Non pressure-resistant areas are bony bumps, nerves, and other areas that can't be compressed or that can cause nerve paralysis. Press the table with the finger belly and other parts of the table press the finger jelly is certainly not an effect, not to mention the sensitive stump end of the bone raised after amputation. Unlike the inner liner, the silicone liner is like a layer of skin attached to the outer layer of the stump, which is equivalent to wearing socks on the outer layer of the skin. The process of wearing the prosthesis is just like wearing shoes. The shape and characteristics of the silicone liner make the stump with non-standard shape form a standard shape after wearing, which reduces a lot of unnecessary trouble for prosthetic users.
Protects skin and pressure structures and increases blood circulation. Silicone liners are also a boon for burn victims, thromboangiitis obliterans and diabetic amputationss. First of all, for the skin of burn patients and skin grafting patients, the structure close to the stump can effectively protect the skin. Special elastic structures can also help vasculitis, which increases blood circulation in patients with diabetes and reduces the risk of blood clots. A small number of users with too sensitive nerves will not stand the constraint of the silicone liner, and some of them are neuroma patients caused by nerve regeneration after amputation. In order to wear comfortable clothes and improve the quality of life in the future, you can go to the surgery to check, and if necessary, you can consider surgical resection of the neuroma.
 
Allergic eczema pruritus skin, it is possible that the skin is allergic to some skin protectants infiltrated into the silicone.
