Abstract

Trigger Finger is a symptom in which the fingers are locked on the finger bent and cannot be easily
reversed. It is caused by a thick inflammation of the inch-muscular casing. The tendon and muscle
inside are not normally retractable. If symptoms are severe, it should be treated with surgical
procedures. After surgery, there must do physical therapy and exercise the fingers. Therefore, this
project aims to create Finger exercise equipment after surgery for patient with severe trigger finger. By
using designing technology, 3D printing and to increase exercising and physiotherapy options after
surgery of the patient after surgery trigger finger. The operating procedure are first, Design the
equipment structures with the Tinkercad 3D design program that design of 5 fingers case and pads for
servo motors. Second, Print the structures of finger device with 3D printer, Fused Deposition Modeling
(FDM). Third, Create a palm plate. Fourth, Assemble the fingerprint case and put the motor on the
surface of a palm plate. Fifth, Input the code on Arduino board to control Servo Motor which pull cases
of 5 fingers. The motor will pull the tendons attached to the joints of the machine at the finger to pull
the fingers. The result is we can create the finger exercise equipment after surgery for patient with
severe Trigger finger by 3D Tinkercad design program and 3D printing. And the result of basic trial is
this equipment can be used as well.
