Prosthetic socket is the link between the stump and the prosthesis. It plays an important role in the prosthetic. It has the function of suspending the prosthesis, containing the stump, transmitting the movement and force. Wearing silicone inner liner can provide comfortable feeling for amputees, at the same time, it can effectively protect muscle tissue, skin surface layer and help to suspend the receptive cavity. The remnant limb wearing silicone inner liner for the first time may shed a lot of sweat, and in most cases, it will reduce to disappear after a period of adaptation and adjustment. The silicone inner liner can wrap the surface of the whole stump comfortably, protect the sensitive skin and scar tissue, promote and improve the blood circulation, reduce the abrasion caused by the hard edge of the receptive cavity to the skin, prevent the traction of the distal skin, and keep the stump in a healthy state. The silicone inner liner is made of low allergic medical grade environmental protection material silica gel, and with active skin ingredients, it can effectively moisten the skin and form a protective film on the skin surface, which can soften the skin, relieve itching, prevent skin allergy and help skin metabolism, so as to make the stump more healthy.

The silicone inner liner with lock provides a reliable suspension. The silicone inner liner is locked with the hard receiving cavity by the locking device, so the amputee's sense of weight on the prosthesis is is no longer like hanging and swaying. The reliable suspension lock does not need to be restricted by the suspension device of the receiving cavity. It has good appearance, and can reduce the energy consumption during long-distance walking, improve the control of the residual limb on the artificial limb, and make the walking safer and more natural.

The silicone sleeve of sealing ring is suitable for patients with middle and long amputation. Through the principle of vacuum suction, the socket and stump can be absorbed to a great extent, which greatly reduces the piston movement generated by the residual limb and the receiving cavity during the walking process, so as to keep the stump in a healthy state.
