多機能化を目指した折れ曲がり変形型内視鏡の開発

抄録

The outer diameter of a rigid and flexible endoscope is limited because of the small incision for insertion of the endoscope, and thus it is difficult to incorporate several functions. In this research, a multifunctional bending transformative endoscope with a small diameter for insertion was developed. The tip of the endoscope is divided into three sections, and it can be transformed by manipulating wires from outside the body. Models of this bending type endoscope, which has two CCD cameras for 3D vision and rear view, were fabricated. Insertion of a forceps through its working channel was also demonstrated.
