The importance of the prosthetic socket
If you ask me what is the most important part of a prosthetic leg? Then I can tell you very clearly that the answer is prosthetic socket. Because of all the components, only the socket is hand-built by the prosthetic technician, whether it is comfortable or not is directly related to the production level of the prosthetic technician. The prosthetic socket directly contacts the residual limb, supports the weight of the human body, and controls the movement of the prosthesis. Therefore, the prosthetic socket is an important structure that affects the wearing comfort and function of the prosthesis, and it is also the soul of a prosthesis.
Generally speaking, the receiving cavity should be replaced every 2-3 years, because the residual limbs are atrophy, especially those who are newly fitted with prostheses, the receiving cavity may need to be replaced in one year. After the degree of atrophy stabilizes, if the receiving cavity is not damaged or uncomfortable, there is no need to replace it.
When assembling the prosthesis, be sure to achieve the most comfortable state, that is, there is no bad feeling at the bottom of the stump. If there is any discomfort, please communicate with the prosthetic technician in time to adjust, because the inappropriate receiving cavity will cause great damage to the stump. For example: pain, redness, blackening, congestion, ulceration, etc.
The receptacle and joints are different in the actual use of the prosthesis. A good receptacle can make you walk comfortable, and a good prosthetic joint can meet your higher sports and safety needs. The two are mutually exclusive. Affect the relationship. The generally accepted order of importance of each component of a prosthesis is:prosthetic socket>prosthetic joint>prosthetic foot plate>connecting tube.
From this ranking, everyone can also see that a prosthetic company is not a company that simply sells goods, but a company that coexists with technology and services. Therefore, even if it is the same joint and foot plate, the quotation of each prosthesis company is different. Friends who don’t understand are likely to choose the cheapest one directly after comparing the prices. A big loss. The core of the prosthetic company is the four tasks of receiving cavity model making, prosthetic assembly and debugging, gait training guidance and after-sales maintenance service. This is why even if two people in the same situation are equipped with the same prosthesis, there may be big differences in gait. Some prosthetic companies will only fool their customers into installing high-priced products, or even discredit their competitors. Such companies will not serve customers with all their heart, and don't expect them to make good prostheses. When you go to a prosthetic company, you should feel attentively and check whether their services are in place. Even a prosthetic company with good products and comprehensive products, without first-class services, will become a third- and fourth-rate prosthetic company. When we go to a prosthetic company, we can observe the sanitation of the training environment and whether the training equipment is complete, whether there is a scientific training schedule, and the sanitation of the workshop and the model room. These details often reflect the professionalism of a prosthetic company. If it is convenient to do well in this company, then their technology will not be too bad. Finally, I will sort out the key points of the article: when assembling a prosthesis, first consider the technology and services of the prosthesis company. The receptive cavity is the soul of the entire prosthesis. If it is done, it is an assistive device, and if it is not done well, it is a torture device. When purchasing prosthetic joints and other parts, you need to consider your own situation. It is not that the more expensive the better, the most important thing is to choose the right prosthesis within your controllable price range. Rehabilitation training and after-sales service are also very important. An experienced rehab can help you avoid many detours and teach you to better master the use of prostheses. Good after-sales service can use prostheses without worries and avoid subsequent problems. Dealing with the situation.
