Abstract:
The prosthetic socket is the mechanical interface between an amputated limb and the
prosthetic leg. Nowadays conventional prosthetic manufacturing process is derived from
an old and artisan technology which is passive, manual and require huge experience of
prosthetist. Person with limb amputation experience huge discomfort because as the time
passes their limb tissue changes its shape but the socket structure remains same. The load
now may distribute on bone and hard tissues rather than soft tissues producing trouble for
patients. The solution of this difficulty is in the field of digital prosthetic socket design
which seeks to advance in CAD methodology for the manufacturing of sockets. In this
report a technology is designed, built, and evaluated namely Fitprosthetics which is a single
indenter device to measure the stiffness off an amputated tissue. Fit prosthetics has three
parts. First one is mechanical designing, second is electronics and the third one is software.
In this report, the mechanical description module covers the working mechanisms of
Fitprosthetic, the electronics module covers all required electronic components and their
assembly on PCB and the software module covers all the programs required to automate
the whole process. Moreover, the values extracted from indenter system can be 3D plotted
for biomechanical data from limb. This data assists in calculating and visualizing the tissue
density and stiffness. This will assist the rapid manufacturing of prosthetics socket. The
3D printed socket fits more comfortably with amputated tissue, it is cheaper, takes very
less time in manufacturing, and can be reproduced and can be manufactured multiple times
