Description

Technical Field

[0001] This utility model relates to the field of prosthetics technology, specifically to a prosthetic socket with antibacterial function. Background Technology

[0002] Prostheses, also known as artificial limbs, are artificial limbs used by amputees to compensate for the function of the missing limb. There are upper limb prostheses and lower limb prostheses, which are mostly made of materials such as aluminum plates, wood, leather, and plastic. Their joints are made of metal components. At present, the mainstream materials in the prosthesis industry are titanium alloy and carbon fiber. Prostheses refer to artificial limbs used to replace limb functional impairments (whether temporary or permanent) or to cover up limb injuries. The biggest difference between prostheses and artificial bodies (such as breast prostheses, artificial noses, wigs, etc.) is that prostheses are more functional and refer only to the upper and lower limbs. Prostheses also include artificial legs.

[0003] Currently, the prosthetic legs used in the market have simple structures and limited functions. They lack antibacterial and ventilation functions, which can easily lead to the growth of bacteria and excessive heat in the parts of the prosthetic leg that come into contact with the user, making them unsuitable for use.
