Description

Technical Field

[0001] The invention relates to the technical field of bionic legs, in particular to a prosthetic receiving cavity with antibacterial function and a use method thereof. Background Art

[0002] Prosthesis, also known as "artificial limb", is an artificial limb used by amputees to compensate for the partial function of the missing limb. There are upper limb prosthesis and lower limb prosthesis, which are mostly made of aluminum plates, wood, leather, plastic and other materials, and their joints are made of metal parts. Now the mainstream materials in the prosthetics industry are titanium alloy and carbon fiber. Prosthesis refers to artificial limbs, which are used to replace limb dysfunction (whether temporary or permanent) or to conceal limb disability. The biggest difference between prosthesis and artificial body (such as artificial breast, false nose, wig, etc.) is that prosthesis is more functional and refers only to the upper and lower limbs. However, recently some people have also included artificial penis or artificial vagina, and prosthesis also includes artificial legs.

[0003] The artificial legs currently used in the market have a simple structure and a single function, and do not have the function of antibacterial ventilation, which can easily lead to the breeding of bacteria and moisture and overheating in the part that contacts the user's artificial legs, which is not conducive to the user's use.
