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

Abstract

The invention relates to a self-adaptive connecting piece based on the connection of a human artificial limb and a residual limb. The connecting piece comprises an artificial limb receiving cavity andan auxiliary part, wherein the artificial limb receiving cavity comprises an outer barrel and an inner barrel, and the inner barrel is a movable barrel and can move along with the walking gait of a human body; and the outer barrel is a supporting barrel which mainly plays a supporting role and provides supporting force for the inner barrel and lower limbs. Two baffles at the left and the right ofthe outer barrel block fixing arms at the two sides of the inner barrel so as to prevent the inner barrel from moving left and right. The two fixing arms are attached to the inner barrel, so that theinstability of the motion with the artificial limb caused by the forward and backward movement of the inner barrel is prevented. A spring is arranged between the inner barrel and the outer barrel toserve as a mechanism for realizing buffering and increasing walking comfort. The auxiliary part is a fixable artificial limb inner lining, and increases the reliability of the connection and wearing of the residual limb and the artificial limb. The artificial limb receiving cavity is of an open structure, the wearing and walking comfort is obviously improved compared with that of a common receiving cavity, and the artificial limb receiving cavity is provided with a sensor for detection so as to provide better guarantee for a wearer, and the artificial limb receiving cavity has good self-adaptability.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an adaptive connector based on the connection between a human prosthesis and a residual limb. Background technique [0002] The residual limb socket is the cavity part connecting the residual limb and the prosthesis. It is in direct contact with the residual limb and plays a vital role in the wearing comfort and human adaptability of the prosthesis. According to the World Report on Disability, by 2015, about 1 billion people in the world lived with mild or severe disabilities. Among them, the number of physical disabilities ranks third after hearing and speech disabilities and intellectual disabilities. And the number of people with disabilities in the world is continuing to grow at a rate of 5% more than expected. According to the statistics of the China Disabled Persons' Federation at the end of 2010, the total number of disabled people in China was 82.96 million, o...
