Types of prosthesis tube adaptors
The prosthesis is composed of receiving cavity, connector and simulation parts. The main materials of prosthesis tube adapter are as follows:
In fact, in addition to the connecting disc and tube connector of the receiving cavity, the rest are basically two materials or a combination of multiple materials.
Stainless steel prosthesis tube adapter
It is mainly used in the connecting plate of the receiving cavity, such as the four claw and three claw connecting plates, of course, there are pipe joints, and the ankle of the low-end ankle foot is also made of stainless steel. This kind of material is the most economical one. Its price is cheap and its performance is very good. The only disadvantage may be its relatively large weight.
Aluminum alloy prosthesis tube adapter
It mainly appears in pipe fittings and joints, such as the pipe part and joint part of prosthesis. Aluminum alloy prosthesis tube adapter is the most common.
Titanium alloy prosthesis tube adapter
It is widely used in middle and high-end prostheses. All stainless steel parts are made of titanium alloy, which is 30% - 40% lighter than stainless steel. Don't underestimate this 30%. If all the connecting parts are made of titanium alloy, the weight can be reduced by about 300-500g, and it will be lighter and more used in thigh prostheses. This kind of material's accessories are much more expensive than stainless steel's price, but its performance is superior to stainless steel's in all respects. It is solid and can be used. But sometimes the market price is three or four times lower than that of stainless steel.
Carbon fiber prosthesis tube adapter
This kind of material mainly appears in the "pipe" in the connection fittings. Why do I add a quotation mark? Because all carbon fiber pipes and joints are made of other materials, such as titanium alloy, stainless steel and aluminum alloy. This kind of carbon fiber tube is lighter than aluminum alloy, and it is hard. It is an ideal pipe for prosthesis connection. If the patient can accept the price, he should choose this kind of prosthesis tube adapter.
