Problems solved by technology

[0004] In view of the above problems in the background technology, the object of the present invention is to provide a calf prosthetic device, which is used to solve the problem that the temperature in the prosthesis receiving cavity is too high or too low to cause damage to the residual limb, and the residual limb is worn for a long time. Prosthetics are prone to muscle strain and atrophy

Embodiment Construction

[0021] The following is further described in detail through specific implementation methods:

[0022] The reference signs in the drawings of the specification include: receiving cavity 1, outer layer 1.1, annular semiconductor cooling plate, inner layer 1.3, damping mechanism 2, cylinder body 2.1, piston 2.2, piston rod 2.3, damping liquid 2.4, damping liquid hole 2.5 , Jacking spring 2.6, one-way valve 2.7, annular piezoelectric ceramics 3, briquetting block 4, prosthetic upper part 5.

[0023] The specific implementation process is as follows:

[0024] Such as figure 1 As shown, a calf prosthesis device mainly includes a socket 1 connected in sequence, an upper part of the prosthesis 5, a lower part of the prosthesis and soles of the prosthesis, all of which are mentioned in the prior art, and will not be done in the embodiment of the present invention. Much elaboration.

[0025] The technical point of the present invention that differs from the prosthesis in the prior ar...

Abstract

The present invention relates to the technical field of prostheses, in particular to a shank prosthesis device. A receiving cavity comprises an inner layer and an outer layer, a gap is formed betweenthe inner layer and the outer layer, a lower portion of a prosthesis comprises a damping mechanism and a piezoelectric ceramic power generation mechanism, the piezoelectric ceramic power generation mechanism is located above the damping mechanism, a lower end of the damping mechanism is fixedly connected with a prosthesis sole, an upper portion of the prosthesis is of a hollow structure and also provided with a storage battery inside, the storage battery and the piezoelectric ceramic power generation mechanism areelectrically connected, the upper portion of the prosthesis is alos internally provided with a massage device and a temperature control device, and the massage device and the temperature control device are electrically connected with the storage battery. The technical scheme is used for solving problems that temperatures in the receiving cavity are too high or too low to injure a residual limb and muscle strain and atrophy easily occur when the residual limb wear the prosthesis for a long time.

Description

technical field [0001] The invention relates to the technical field of artificial limbs, in particular to a calf artificial limb device. Background technique [0002] Nowadays, there are more and more thigh amputations due to various injuries caused by diseases, industrial injuries, traffic accidents and natural disasters. Amputation is a destructive operation. After the original soft tissue and muscles are removed, the residual limb will be Lost the original body function, and because the amputee patient has not been exercised for a long time, the muscle strength and joint mobility of the residual limb are obviously insufficient, which causes local muscle atrophy and deformation, and the loss of lower limb motor function, which leads to slow recovery of the patient, etc. series of questions. The functional recovery exercise of the residual limb can enhance the muscle strength of the thigh, improve the range of motion of the joint, and enable the prosthesis to better perfor...
