Abstract

This work aims to present an innovation never seen before or released in the marquet through an authorial and interdisciplinary approach. The innovation is a flexible stems cilindric medical device to rearrange broken bones, whose functionality will be evaluated and improved according to the objectives. Classified as a compliant mechanism, the prototype is essentially related to biomimicry due to its flexibility, how suggests the book Compliant Mechanisms by Larry Howell. Also, because of this property, the device has the possibility to offer advantages in relation to the current bone fixation gadgets available, considering that they are within the book scope. The project actuation area is biomedical engineering, for this reason it requires basic level of acknowledge on biocompatible materials and human anatomy specialized on orthopedy. However, the main project subject is the flexible materials analysis, machine design and rotational kinetic, as well as the fabrication processes, costs and device accomplishment. Thus, the device reproduction through the prototype will be limited to the three manufacture methods, which are: Hot grue, 3D print and rapid liquid printing. However, the already used flexible bioinspired material study will serve to amplify the material possibilities beyond the feasible in this project. The graphic computing will have a essential role at the visualising and performance in the building process, moreover, it will allow the key stress point identification in the virtual device.
