How To Choose The Best Quality Prosthesis?
Jun. 11, 2019
The concept of modern Knee Preservation Surgery Prosthesis should have the following characteristics:
1) Features of simple component adjustment at any time;
2) Features of functional parts that vary from person to person;
3) characteristics of minimum physical energy consumption;
4) Features of safety, beauty, and quality.
For the above reasons, the following factors should be considered when selecting an artificial limb by an amputee:

1) Product weight
Residual limbs should pay more physical energy than normal people. If the prosthesis is too heavy, the energy consumption will be greater. Therefore, reducing the weight of prosthetic parts is one of the important indicators to measure its function. Modern prosthetic materials are basically made of carbon fiber, magnesium alloy, titanium alloy, aluminum alloy, and other light metal materials. Among them, high-quality carbon fiber is the most ideal material at present, lightweight, moderate toughness, and durability. The new material magnesium alloy is increasingly showing its advantages; its density is small, its weight is 30% lighter than aluminum, 20% lighter than plastic, its shock absorption performance is good, and it has no pollution to the environment.
2) Product quality
In general, the quality of a product is a comprehensive evaluation indicator that determines the durability, safety, and aesthetics of prosthetic joints and parts. Excellent prosthetic products must have very strict design and development, production and manufacturing processes, technical assembly and post-service management and other procedures to ensure. Only those world-renowned companies that have achieved international standards such as ISO9001, CE and EN46001 can complete this.
3) Assembly technology and training space
Prosthetic assembly technology is a comprehensive technical performance of human anatomy, mechanics, prosthetics, materials science, mechanical kinematics, rehabilitation knowledge, etc. It is a quality embodiment and continuation of an excellent product. The application and planning of training facilities and venues reflect the ability of people with disabilities to adapt to society after returning to society in the future.
4) Product adaptability
Excellent prosthetic products should be more suitable for the different needs of various types of residual limbs. According to the weight, age, activity, physical fitness and physical strength of the amputee, it is reasonable to choose the product that suits oneself, that is, the new prosthetic assembly theory that satisfies the "prosthetic fit". The world-renowned prosthetic company, which has a long history of 115 years, is the only spokesperson for this assembly theory.
5) Accepting cavity making technology
The suitability of the residual limb and the prosthetic cavity is one of the important factors to measure the success of the entire prosthetic production. If the artificial limb receiving cavity production technology is not controlled or operated by non-professional technicians, it will cause unnecessary problems such as wearing pain, discomfort, and broken skin, and even indirectly causing deformity of the thoracic spine in the future. Get good gait and it is difficult to adjust. This is also the main reason why many disabled people can't trust and lose confidence in wearing artificial limbs. It is also the main reason why the Ministry of Civil Affairs and the Ministry of Personnel have implemented the appraisal system for prosthetic practitioners in recent years.
6) Quality of service
The embodiment of service level is no longer a requirement for the process of assembly of the disabled, and the real service should be a commitment to the quality of the product after the assembly is completed. Only a formal enterprise that integrates R&D, manufacturing, assembly, and service into one, and has a considerable assembly scale, and a company with relevant national departments, equipment testing, and prosthetic qualification certificates can provide high-quality post-service.
