Abstract
This paper describes the recent research and development of an endo surgical/biomedical instrument in surgical suture applications for minimally invasive therapy procedure. The newly developed instruments can not only protect the wound during the surgical procedure but also actively help the healing process. The new mechanism design of the surgical instrument aids in better ergonomic design, reliable functionality, and continuous cost reduction in product manufacturing. 3-D modeling technique, functionality analysis, kinematical simulation and computer aided solution have been applied to the instrument design, development and future improvement to meet the specific requirements of minimally invasive surgery procedure. The improved new endo surgical/biomedical instrument can prevent patient’s vessels and tissues from being damaging because the distal move of clips are well controlled without clip drop-off incident. Plus the operational force to form the clip is lower than regular surgical/biomedical instruments due to this special new mechanism design. In addition to the above, the manufacturing and product cost can be decreased because the dimensional tolerance of components, such as clip channel and jaw guide track, can be loose due to this new instrument design. The prototypes of this new endo surgical/biomedical instrument design are analyzed through computer aided modeling and simulation, in order to prove its feasible functionality, reliable performance, and mechanical advantage. All these improved features have also been tested and verified through the prototypes.

Summary
The newly developed technologies have directed minimally invasive surgeries [1]. The positive and feasible changes in surgical instruments have led to the new development of surgical techniques [2] and [3]. The recent studies show the versatility of endo surgical clips in therapeutic and endoscopic applications This endo surgical instrument is the innovative product that will allow for greater ease of use for surgeons and help to improve patient outcomes. Based on the field and clinical feedback, the new technology that simultaneously opens and aligns the jaws has been implemented, allowing well controlled surgical clip feeding and closure. This new surgical instrument design can provide more consistent and reliable mechanism to protect the clip from external and unanticipated disturbance while the surgical clip sits in the jaw track. Comparative studies between endo surgical clips and thermal therapy verify that endo surgical clips cause less trauma to the mucosa around the ulcer than electrocautery
