Embodiment Construction

[0040] Using metal and polymer materials, injection molding is used to produce the bone ends of artificial residual limbs (see Figure 10 ), the steps include: firstly make an artificial residual limb bone end suitable for the size of the femur to be connected, which has no joints and is composed of two parts, the upper end is the insertion part, and the outer diameter of the insertion part should be suitable for installation on the connected femur. In the femur, the lower end is an enlarged part with a flat bottom that can bear all the body weight; secondly, the surface of the insertion part is made into a regular uneven shape with longitudinal grooves; finally, at the connection between the expansion part and the insertion part, make Create a step that fits the femoral endface to be connected. At the same time of amputation, use the method of implanting artificial joints to insert the insertion part of the bone end of the artificial residual limb into the cavity of the conne...

Abstract

The artificial meromelia extremity without joint has an end to be fitted with meromelia bone and an enlarged part at the other end to suspend artificial limb and bear boby's weight. It is made of one or several kinds of metal, ceramic, polymer, plastic and other materials through molding or machining. Its upper end as inserting part has outer size fitting the cavity of the meromelia bone to be connected and embossed surface with longitudinal grooves and its enlarged lower part has a boss to be contact with meromelia bone at joint with the inserted part. The artificial meromelia extremity can be connected closely with meromelia bone for facilitating the installation and use of artificial limb.

Description

technical field [0001] The invention relates to an artificial residual limb bone end and a manufacturing and installation method thereof, in particular to an artificial residual limb bone end capable of good load bearing and a manufacturing and installation method thereof. Background technique [0002] At present, artificial joints have been widely used at home and abroad, avoiding the physical disability and amputation of tens of millions of people. However, this technology can only be used to replace damaged human joints. For the amputated residual limbs, artificial joints in the body cannot be applied. Only prosthetics can be fitted. [0003] The part of the prosthesis connected with the residual limb of the human body is called the socket, which is a cavity that is made to match the shape of the residual limb by taking a mold from the residual limb. For lower limb amputation, because most of the bone ends of the residual limb cannot bear weight like the soles of the fee...
