Laparoscopic surgery and catheter surgery become popular as minimally invasive surgery. It is important to develop micro forceps for more delicate operation at the delicate area. Development of micro forceps need advanced processing technology to make minimum parts. Moreover it is necessary to design the holding mechanism that's compose of extremely few parts, and develop the material it's not broken while operating even if the size is downed. In this study we designed micro forceps that's compose of four parts, those are two holding parts (width 0.5mm), an exterior pipe (diameter 1.0mm), and spring (line diameter 0.05mm). Then we succeed in making prototype of micro forceps, it is made by Metal Injection Molding technology.
