![]() The circumference of Medi-Rehatek suction-type prosthetic socket is generally shorter than the circumference of the residual limb.The mouth is close to quadrilateral in order to maximize the residual function of the stump.When an amputee wears prosthesis, a cloth is attached to the surface of the residual limb, and the cloth is pulled out through a vent in the wall of the prosthetic socket, and the residual limb can enter the prosthetic socket. In this manner, a negative pressure is generated between the residual limb and the prosthetic socket during the swinging period.And this negative pressure acts as a suspension prosthetic socket. Suction-type socket with free movement prosthetic knee does not need suspension belt and waist belt, the length of thigh prosthesis can also be as long as the healthy leg. ![]() The features of suction-type prosthetic socket: 1, Amputee feels easy to wear 2, This socket does not like the plug-in socket that produce internal muscle uplift 3, Thigh prosthesis can move easily with tempo of the residual limb 4, The socket does not need waist belt, so the waist skin will not be damaged, but also is suitable for pregnant and obese amputees ![]() 5, The suspension performance of prosthetic socket is good, it won’t occur in standing on tiptoe during walking in swing period.So the other side of the lower limbhas related diseases and paralysis or amputees with both of lower extremity can also use 6, The socket does not produce convolution phenomenon like plug-in prosthetic socket as the pelvic movement in the swing period Relative blog: How to choose fit below knee prosthesis
