Our assignment is to discuss lower limb prostheses (specifically about amputations done below the knee). As can be seen from the literature review I attached (this file is nothing major regarding the task to do, just that prosthetics has many components so don't look at it much) prosthetics have many components.
The component that I want to be discussed is the socket part. As said previously, we are mainly discussing about prosthetics that are attached below the knee (transtibial amputations). So talk about sockets in prosthetics below the knee. I attached an example a friend wrote about sockets (file named 'socket prosthetics"), so maybe this can be used as a guide. There is no need for a lot of introduction regarding sockets, maybe two sentences? But, the main idea here is to discuss about its material, how it is used and what type of sensors are incorporated in sockets (important!). Also mention since there are many types of sockets available, the main socket to discuss is 'patella tendon bearing. It is a common design used in sockets of transtibial prosthetics.
Since many of the proposed sockets available for prosthetics are made of carbon fiber, for our assignment we are trying to propose a titanium-material socket. Discuss about the advantages of having the socket be made of titanium, (which has more durability, and comfort) instead of using regular other materials like carbon fiber, etc. This is also very important.
This has nothing to do with the socket section, but I will attach this guide as well (foot design file), just like the socket design attachment. Since prosthetics have many components, and as can be seen from the figure, a friend did the 'bionic foot ankle component. Like the socket prosthetics file I attached, this foot design file Maybe can be used as a guide to what to focus on when talking about sockets. What main parts that should be discussed in this assignment.
The main thing is about sockets, but not just any sockets, sockets in prosthetics that are below the knee (because there are sockets for thighs but this is not our task)
Include - Sensors used, material (propose a titanium material, its advantage), sockets mainly patella tendon bearings how they are better etc
