[0002] A prosthesis, also known as a prosthetic limb, is an artificial limb used by amputees to compensate for the function of the missing limb. There are upper limb prostheses and lower limb prostheses. They are mostly made of materials such as aluminum plates, wood, leather, and plastic, with metal components for the joints. Currently, titanium alloys and carbon fiber materials are the mainstream materials in the prosthesis industry. A prosthesis refers to an artificial limb used to replace a limb's functional impairment (whether temporary or permanent) or to conceal limb injury. In the prior art, patent number CN202322067466.0 discloses a thigh prosthesis socket, including a socket body. The socket body has a resection cavity disposed downward on one side of the inner thigh. The resection cavity is provided with tension adjustment components spanning the resection cavity on both sides. The tension adjustment components include an elastic band connected to one side of the resection cavity and a connecting buckle disposed on the other side of the resection cavity. One end of the elastic band passes through the connecting buckle and is detachably connected to itself by a Velcro assembly. The aforementioned patent also has some shortcomings.
