Design and development of a new endo biomedical surgical instrument

Abstract

This paper describes the recent research and development of an endo surgical/biomedical instrument for minimally invasive therapy procedure. The new mechanism design aids in better ergonomic design, reliable functionality, and continuous cost reduction. 3-D modeling technique, functionality analysis, and computer aided solution have been applied to the instrument design and development The improved instrument can prevent patient's vessels and tissues from being damaging because the distal move of endoclips are well controlled without clip drop-off incident. Plus the operational force to form the clip is lower than regular surgical/biomedical instruments Also the manufacturing and product cost can be decreased because the dimensional tolerance of components can be loose due to this new instrument design. This new endo surgical/biomedical instrument design has been analyzed through computer aided modeling and simulation to prove its reliable performance and mechanical advantage. All these improved features have also been tested and verified through the prototypes.
