How long can prosthetics be used? I figured it out myself, I'm not afraid of the salesman slipping through the cracks!

Artificial limbs are a necessity for people with physical disabilities, as they can release both hands and help amputees better integrate into society. Many amputees are concerned about one issue when installing prosthetics.

How long can prosthetics be used?? The editor will popularize the relevant knowledge of prosthetics, so that everyone can have a good understanding of how long prosthetics can be used..

We introduce two concepts: "loading frequency" and "load value";

What is loading frequency: refers to the maximum number of times a carrier (such as a prosthetic joint or component) can continuously and intermittently withstand load values without deformation or damage.

What is load value: It refers to the theoretical value of the external forces (such as torsion, torque, tension, shear force, axial force, etc.) that a carrier (such as a prosthetic joint or component) must withstand according to relevant standards (such as national or international standards)..

Relevant regulations on "loading frequency" and "load value";

Taking the following limb prosthesis as an example, according to GB 14723-2008 document 6 7. Strength requirements: For components that bear loads, structural strength tests shall be conducted in accordance with GB/T 18375 (equivalent to the international standard ISO 10328), and no cracks, damages, obvious permanent deformations, or abnormal sounds shall occur.

Simply put, the strength requirement for the prosthetic foot and joint of lower limb prostheses is that the qualified load value for domestic products is 1 million times, and the qualified load value for international products is 3 million times..

Regarding the service life of prostheses;;

As mentioned above, the qualified load value for domestic products is 1 million times, and the qualified load value for international products is 3 million times.. Let's take a look at how many steps we can take every day.

Because everyone uses prostheses differently, the lifespan of prostheses also varies from person to person.

You can know how long your prosthetic can last based on the following formula

If your prosthetic is domestically produced, its lifespan is 1 million. ➗ （365 ✖ The average daily steps) If your prosthetic is imported, its lifespan is 3 million ➗ （365 ✖ Average daily steps)

Do you know how long your prosthetic can last?

Everyone can apply the above formula according to their own usage situation, and the service life obtained can indicate that your prosthetic is about to reach the critical point.. At this point, one's prosthetic related components may need to be replaced.
