China's best-selling titanium alloy, stainless steel prosthetic connector

[Abstract]:
  We know that a prosthesis is composed of a receiving cavity, a connector, and a simulation component. The naming of the material here is sometimes very confusing. Some amputee friends feel that they are particularly tall and expensive when they hear about carbon fiber. In fact, many times, it is not as we imagined. Let's take a look at the selection of these connectors.

China's best-selling titanium alloy, stainless steel prosthetic connector

 

     We know that a prosthesis is composed of a receiving cavity, a connector, and a simulation component. The naming of the material here is sometimes very confusing. Some amputee friends feel that they are particularly tall and expensive when they hear about carbon fiber. In fact, many times, it is not as we imagined. Let's take a look at the selection of these connectors.

The main materials of these miscellaneous connecting parts are nothing more than the following: 

In fact, except for the connecting plate and the pipe connection of the receiving cavity, the rest are basically two materials or a combination of multiple materials. 

stainless steel

It is mainly used on the connecting plate of the receiving cavity, such as the four-claw and three-jaw connecting plate, and of course the pipe joints. The ankle of the low-end movable ankle foot is also stainless steel. This kind of material is the most economical material. It is cheap and has good performance. The only drawback may be the relatively large weight.

Aluminum

Mainly appear on pipe fittings and joint parts, such as prosthesis connecting pipe parts and joint parts. Aluminum alloy tubes are the most common.

Titanium

It is widely used in middle and high-end prostheses. All stainless steel parts are available in titanium alloy versions, and are 30%-40% lighter than stainless steel. Do not underestimate this 30%. If all connecting parts are made of titanium alloy, the weight can be It is reduced by about 300-500 grams, and it will be lighter when applied to the thigh prosthesis. The accessories of this material are much more expensive than stainless steel, but the performance exceeds that of stainless steel, and it is strong and used. But sometimes the market price is three or four times worse than that of stainless steel.

Carbon fiber

This kind of material mainly appears in the "pipe" in the connection fittings, because all the carbon fiber pipes and joints are made of other materials, such as titanium alloy, stainless steel, and aluminum alloy. This carbon fiber tube is lighter than aluminum alloy, and it is unusually hard. It is a very ideal prosthetic connecting pipe. If patients can accept the price given, they should choose this tube .
