Pemilihan Desain Prosthetic Jari Tangan Berdasarkan Mekanisme Sistem Penggerak Cross Bar dan Cross Cable terhadap Besar Gaya Tarik Dinamis Prosthetic Jari Tangan
Abstract: The absence of the
hand causes the disruption of organ function, this problem later emerged
prosthetic as a tool for replacement of missing body parts. Basically
prosthetic hand has two functions: as cosmetics and as a functional tool. The
most important functional aspects of prosthetic hands is the ease of operation
that can be seen from the magnitude of tensile force required by prosthetic
hand while doing the a movement. The mechanism of motion system that is widely
used by prosthetic hand is a cross cable system and cross bar system. Cross
cable systems using cable to connect components that act as links knuckles on
hand, when the withdrawal event of the cable happened, the cable will be
tightened and the movement of the fingers may occur. Cross bar systems uses bar
(rigid link) as a puller, so when withdrawal event of the rope at the end of
the lever happened, the bar that connects the components with a finger lever
puller will push or pull bar so that the finger will open or close. Prosthetic
design significantly influence the magnitude of the dynamic tensile strength that
makes it necessary to make an experiments to compare the design of motion
mechanisms of cross cable systems and cross bar system, and evaluate the
influence on the magnitude of the dynamic tensile force at the time of
movement, so it can represent the natural movement of normal human fingers.
