Simulation of Chinese finger grip braided sleeve designs for transtibial prosthetics

This work focused on the development of a below knee prosthetic that designed to eliminate various discomforts that are commonly prevalent among the general population of the amputees. The major parts of the transtibial prosthesis are foot, pylon, socket and sleeve. The sleeve-socket compatibility plays an important role in determining the comfort level of an amputee. 'Chinese finger grip braided design' for the sleeve has been proposed by few researchers for better grip and improved comfort level of the amputees. But the detailed design of the braid is not analyzed so far. In this research, two different Chinese finger grip braided designs of the sleeve were proposed and their suitability for transtibial prosthesis was analyzed. The proposed designs were modelled using SOLIDWORKS software and sufficient evaluation of the same has been carried out using OPENSIM and ANSYS software.
