Abstract
One major difference among surgical instruments is the level of bodily disruption and tissue trauma that surgical devices might cause the patients. This newly designed and developed surgical instrument aims at minimally invasive therapy procedure, more reliable and durable function, less operational force, and reduced manufacturing cost. The computer aided modeling and simulation have been applied to help this new instrument design and analysis. This improved new surgical instrument is designed to use in general surgery to prevent patient's vessels and tissues from being damaging due to reliable motion control of surgical clips with no unexpected clip drop. It can also be applied to surgical education purpose to educate medical students for their future surgical careers. The prototype testing indicated that the handle operational force to close surgical clips is lower than current surgical clip instruments, product manufacturing is cost-effective due to less dimensional tolerance control of this new instrument design, more reliable instrument function, and good mechanical advantage.
Highlights
The surgical clip instruments provide function of suturing, occluding, ligating, and clamping
This paper introduces a new surgical clip instrument design through 3D modeling, computational simulation, and prototype testing. 3D modeling and computer aided simulation can help geometrical design and dynamical analysis of new surgical instruments
The unit geometry, mechanical dynamics and visual access of this new surgical instrument have been analyzed to assist the surgeon in surgical procedures
Summary
The surgical clip instruments provide function of suturing, occluding, ligating, and clamping. Suture is a slow process and it might cause the suppuration surround cutting area and patients will have pain feeling when remove the suture [5]. This newly designed surgical clip instrument can help surgeon in their general surgical procedure to prevent surgical clip drop incident, speed up and improve the surgical process. It can be used in surgical education to benefit future surgeons
