Abstract
Surgical treatment of aneurysms requires special instrumentation. Fenestrated clips are useful in cases of limited approach angles and tight workspaces. This paper presents the design concept of a fenestrated titanium aneurysm clip using reverse engineering and specific fabrication techniques. It is starting with obtaining a 3D model of the fenestrated titanium aneurysm clip which is then used to determine the torsional spring parameters. Based on the dimensions of the clip model obtained, it is planned to develop a fabrication technology in the form of jig design, dies, selection of production machines and tools. Reverse engineering models of aneurism clip shows a high similarity in geometrical and mechanical testing. The weakness of this study is the inability to mimicking the blade tip surface. In future work, exploration about blade tip surface machining needs to be improved.
