Embodiment Construction

[0010] Such as figure 1 As shown, the present invention includes a limb connection part, a support bar 3 and a foot plate that act as a calf, and is characterized in that: the limb connection part adopts a frame structure, and the frame structure includes a longitudinal strut 1 and a transverse fixing ring 2, The several longitudinal struts 1 are surrounded to form a columnar frame that coincides with the contact parts of the residual limbs of the human body, and a horizontal fixing ring 2 is fixed on the top of the longitudinal struts 1, and a horizontal fixing ring 2 is fixed on the top of the several longitudinal struts 1. There is a fixed ring, which is connected to the top of the support bar 3 through a hinge connection at the position outside the bottom of the limb connection part at the rear side of the human knee joint to form the first hinge point 9, so that the limb connection part and the support rod 3 can be rotated arbitrarily around the hinged rotating shaft, and...

Abstract

The invention relates to an artificial lower limb. The artificial lower limb comprises a limb connection part, a support rod which plays a role of the shank, and a foot plate, wherein the limb connection part is of a frame structure which comprises vertical struts and transverse fixing rings, and the plurality of vertical struts are enclose to form a cylindrical frame which is matched with the part contacted with a body stump, and more than one transverse fixing ring which connects the plurality of vertical struts into a whole is arranged in the horizontal direction; the outer part of the bottom of the limb connection part is positioned behind the knee joint of a human body, and connected with the top part of the support rod in a hinged connection mode; and the bottom of the support rod is connected to the rear side of the upper surface of the foot plate which is similar to the shape of the sole of the human body. The artificial lower limb has the advantages of simple and smart structure, convenience for assembly and use, flexibility in use, free traveling on uneven road, low cost and light weight.

Description

Technical field: [0001] The invention relates to a prosthetic, in particular to a prosthetic lower limb. Background technique: [0002] With the gradual improvement of people's living standards, the development of our country's social economy and the acceleration of the pace of work, cars have increasingly become a means of transportation that people cannot do without. Therefore, there are more and more cars on the road, and the speed is getting faster and faster. The occurrence of traffic accidents is becoming more and more frequent, so more and more people are amputated. After amputation, in order to facilitate work and life, it is necessary to install artificial limbs, especially for those who lost their lower limbs in accidents. The significance of installing artificial lower limbs is even greater. for major. However, the existing artificial lower limbs have the defects of complex structure, heavy weight, inconvenient installation, use and maintenance, and high price. ...
