Silicone Rubber Used for Lower Limb Prostheses

Abstract

The liner is one of the most important part of the lower limb protheses, whose role is to maintain the contact between the residual limb and the socket. Taking into account the residual limb has a variable volume, we have analysed the closed-cell prototype of the liner made of silicon rubber RTV-2. The mechanical properties of this material could provide the requirements imposed for the lower limb prostheses. Meantime it is innocuous for the human body, especially for skin contact and could be used for medical devices manufacturing.
