Description

Self-adaptive connecting piece based on connection of human artificial limb and stump

Technical Field

The invention relates to the technical field of medical equipment, in particular to a self-adaptive connecting piece based on connection of a human body artificial limb and a residual limb.

Background

The residual limb receiving cavity is a cavity part for connecting the residual limb and the artificial limb, is in direct contact with the residual limb, and plays an important role in the wearing comfort and the human body adaptability of the artificial limb. According to the world disability report, about 10 million people around the world live with either light or heavy disabilities by 2015. And the number of the people with physical disabilities is second to the third ranking of the hearing, speech and intelligence disabilities. And the number of people with disabilities in the world is continuously increasing at a rate exceeding the expected 5%. According to the statistics of the Chinese disabled people association at the end of 2010, the total number of Chinese disabled people is 8296 thousands of people, wherein the number of the physical disabilities is 2412 thousands of people and accounts for 29.07 percent of the total number of the physical disabilities, the number of the physical disabilities comprises 158 thousands of people with lower limb amputation, which accounts for about 70 percent of the total number of the disabled people, and the number of the multiple disabilities accounts for 1352 thousands of people and accounts for about 16.3 percent of the total number of the disabled people.

The development of the artificial limb can only realize the purpose of making up the deficiency in appearance and some simple uses at first because of technical reasons, then a power device is added to provide power, and then the artificial limb is more biased to intellectualization and man-machine coordination, so that the artificial limb is closer to the original limb of the human body. The wearing comfort of the artificial limb is a crucial factor for people to measure the quality of the artificial limb. As a knee prosthesis, when a human body walks, the most critical part is the knee of the human body, and many prostheses have been provided to place a cushioning function in a prosthetic knee joint, such as a pneumatic knee joint and a hydraulic knee joint. An above knee prosthesis is generally composed of three parts, a support member, a body contour trim member, and a prosthetic socket.

With the continuous progress of science and the rapid development of society, the social activities of human beings are more abundant, and the number of disabled people is gradually increased due to industrial injuries, congenital diseases, traffic accidents and natural disasters. The development of the artificial limb can only realize the purpose of making up the deficiency in appearance and some simple uses at first because of technical reasons, then a power device is added to provide power, and then the artificial limb is more biased to intellectualization and man-machine coordination, so that the artificial limb is closer to the original limb of the human body. The socket is the connecting piece of the human residual limb and the artificial limb. Above knee amputation refers to the amputation above the knee joint and below the hip joint. When the human body walks or runs and jumps, the knee joint of the human body has a strong buffer function. The traditional artificial limb generally places a buffer device in a knee joint structure, forms the buffer when a human body walks in the modes of hydraulic pressure, air pressure and the like, and increases the walking comfort level. This results in a more complex knee joint structure and also increases the walking weight of the prosthesis.

For example, chinese patent publication No. CN106667629A discloses an artificial limb socket with a bionic sucker and an open structure, which is sequentially provided with a flexible sucker, a transition layer and a hard cavity from inside to outside, wherein the transition layer is provided with a plurality of hole structures from the inside to the outside, and the hard cavity is provided with a plurality of hollow structures. The flexible suckers are distributed in a scattered point mode and can be stably adsorbed on limbs; the inner side surface of the flexible sucker is provided with densely arranged hexagonal prism bulges, and a groove is arranged between every two hexagonal prism bulges, so that the adsorption stability of the flexible sucker is improved; the transition layer is made of a soft and moderate material, a plurality of communicated hole structures are distributed from the inner side to the outer side, and air holes are distributed on the connecting surface of the transition layer and the flexible sucker; the hard cavity is designed with a hollow structure according to the biomechanical characteristics, so that the weight can be reduced, and the open structure of the whole accepting cavity is realized. However, the flexible sucker, the transition layer and the hard cavity in the receiving cavity are directly fastened together, so that a user wearing the artificial limb feels jerked when walking, and the receiving cavity causes secondary damage to the residual limb.

For another example, chinese patent publication No. CN108926415A discloses a prosthetic socket and a method for manufacturing the prosthetic socket, the socket including: guide port, base, gas vent, sealed wall, outer chamber inner wall and outer chamber outer wall. Specifically, the guide opening is used for embedding the guide pillar in the inner cavity model; the sealing wall is used for sealing a gap between the inner cavity model and the outer cavity model when the inner cavity model and the outer cavity model are combined; the base is used for supporting the inner cavity model and the outer cavity model; the exhaust port is used for exhausting air and detecting the filling degree of the solidified material. However, the socket lacks a buffer structure, so that a user wearing the artificial limb feels a feeling of jerking when walking, and the socket causes secondary damage to the residual limb.
