Milestone 2
Preliminary Design
Before week 2 starts, the bring-home work was to research on related topics: Form, Surgical Fixation and other relevant criteria. With the knowledge that was obtained from the research, we were asked to generate a preliminary design individually and bring to design studio for peer feedback.
The picture on the left is my preliminary design. I proposed the idea that a hybrid total hip implant would the best for our patient. The stem is cemented since the patient is over 60 years old and does not have an active lifestyle. Having a polished stem allows force to transfer through mieromotron and press less pain on the patient's thigh. Cement stem is known for its initial stabilization. The stem is made of metal.
The socket should be cementless which allow the socket to grow into the bone with biomaterials that is similar to bone material and promote bone growth. Metal is also used for the socket component.
I also prompt a unique idea to incorporate magnetic coating on the femoral head and the interior of the liner. Such design uses the repellent of magnets, creating nearly zero friction, while the repellent is not too strong to cause dislocation.
For in the refined concept sketch, we combined all of our ideas.
-
For the socket, we are going to resurface Jackie's socket since it is malformed. The socket implant shake is also based on the original shape of Jakie's socket.
-
for the acetabular and femoral head part, we employed the dual mobility mechanism to increase the range of motion and prevent dislocation which happens at a higher rate in traditional femoral head design.
-
between the exterior acetabular liner and the femoral head, magnetic coating is applied
-
for the stem, we are planning to coat it with Hydroxyapatite to promote bone growth and having artificial vessels implanted on the surface of the stem to deliver drugs/hormones
