Description

Technical Field

[0001] This utility model relates to the field of socket technology, specifically to a knee-disconnected snap-on prosthesis socket. Background Technology

[0002] Prostheses, also known as artificial limbs, are artificial limbs used by amputees to compensate for the partial function of the missing limb. They include upper limb prostheses and lower limb prostheses. They are often 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. Prostheses refer to artificial limbs used to replace functional impairments (whether temporary or permanent) or to conceal limb disabilities. Knee disarticulation snap-on prostheses are a special type of thigh prosthesis suitable for those with knee disarticulation, excessively long thigh stumps (8cm below the knee), excessively short lower leg stumps (approximately 4cm below the knee), and lower leg amputees with severe flexion contractures of the knee joint. The socket is the part of the prosthesis that directly contacts the stump; it usually adopts a full-contact design to better distribute pressure and improve comfort and stability. In the prior art, patent number CN202223412054.8 discloses a shock-absorbing prosthesis receiving cavity, which includes a prosthesis receiving cavity with a prosthesis connector for connecting the prosthesis, thereby connecting the prosthesis for movement. In this shock-absorbing prosthesis receiving cavity, the leg is vertically inserted into the clamping component, and the bottom of the leg rests in the groove of the connecting block. At this time, the two clamping components move away from each other and compress the upper elastic component. The aforementioned patent also has some shortcomings. For example, when using the spring in the clamping component as a shock-absorbing component, the traditional shock-absorbing spring is not convenient for adjusting the shock-absorbing stroke, so the existing technology needs to be improved.
