英文摘要 | During the design and fabricating processes of a prosthetic socket, in order to avoid the impair on the pressure-relief areas of the residual limb, such as tibia, the shape of duplicated plaster mold of the residual limb that is used to make the socket should be modified. The study focused on developing an algorithm that employs the techniques of reverse engineering, theories of B-spline and lofted surface, and lonot insertion method to modify the shape of a residual limb. Once the regions of PT/PR areas of a residual limb have been specified, the selected scanned points are then transferred to the prototype system developed in this study to implement the required modification. A demonstrated case study has verified the algorithm than can automatically meet the required shape change of that specific residual limb. Based on the shape modification algorithm, an automated prosthetic socket design system that is being developed would then be more feasible. |
