Performance of Supermicrosurgery Using a Titanium Needle Holder

Abstract

Development of the supermicrosuture has enabled performance of supermicrosurgery in which microvessels smaller than 0.5 mm in diameter are anastomosed. This surgery has also been facilitated by advances in peripheral equipment, including a needle holder, for accurate handling of the supermicrosuture. However, there are several problems with the stainless steel needle holder, including weight, magnetism and stylized shape, and a new type of needle holder is needed for resolution of these problems. In this context, the EMI Factory Co. used titanium to develop a light, nonmagnetic and convertible needle holder. In this study, we describe a case of pediatric fingertip replantation and we discuss the potential for production of surgical equipment based on a surgical plan, through development of order-specific medical instruments. We suggest that this approach will require close coordination between the medical and industrial fields.
