Transcript of Mechanical Engineering in Prosthetics

Mechanical Engineering in Prosthesis Technology
Myoelectric is one of the most recently used type of prosthesis introduced in 2007.

The iLimb process:
Young Patrick Kane was one of the youngest person fitted for a prosthetic in 2010. Till recently in early 2013 the 16 year old is able to control his prosthesis using his iPhone 5. ( leg and hand)
Mechanical Engineering in Advancing
Prostheses Technology
Prosthetics Used Today
Old vs New
In the past when choosing a prosthesis you had very few options of the materials .
Past
crude
wood in past
Modern
Carbon fiber for a life like material
Thermoplastic sockets for comfort and fitted throughout a lifetime due to shrinkage of the
Titanium for extra durability.
Blue tooth technology
Microprocessor Knees introduced in the 1990s




History of Prosthetic Limbs

Cutting-Edge Technology
Cutting Edge Technology
Earliest prosthesis found dates between 950 and 600 BCE in Cairo, Egypt.
16th century French military doctor, Ambroise Paré, invented a hinged, mechanical hand and a leg with specialized attachment harnesses and locking knee joints.
In 1690, a Dutch surgeon, Pieter Verduyn, developed a lower leg with specialized hinges and a leather cuff for better attachment.
The advancements by these two doctors are still commonly used today.
In 1840, advances in medicine allowed for more successful amputation surgeries. This also allowed for surgeons to prepare the risidual limb for a better fit for a prosthetic.

In 1840, advances in medicine allowed for more successful amputation surgeries. This allowed for surgeons to prepare the residual for a better fit for a prosthetic. After that, the field of prosthetics advanced in joint technology and suction-based attachment methods.
In 1945, The National Academy of Sciences established the Artificial Limb Program in response to the influx of World War II veteran amputees.
