Inventor: TOYAMA RYUICHI
IPC: A61B1/00
Filed: 2001-06-01
Abstract: PROBLEM TO BE SOLVED: To secure a sufficient hardness change against restriction of a coil built in an endoscope for flexibility adjustment to improve inserting performance. SOLUTION: A coil 34 is inserted along the inner wall of a cylindrical strip member 28 in a flexible tube 27. The tip end part of the coil 34 is fixed midway a wire 36 by brazing 26 and a middle part of the coil 34 is fixed to the inner wall of a proximal connecting tube 31 by brazing 35 to extend the tip end part to the rear side of an operating part 3. The tip end of the wire 36 is connected to a connecting tube 19 on the tip end of the flexible tube 27 by brazing 33. The rear end of the wire 36 is extended from the rear end of the coil 34 to the rear side and fixed on the operating part 37. Thus a hardness change is borne by both the coil 34 and the flexible tube 27 when the operating bar 37 is pulled for hardness adjusting.  Even if a hardness change of the coil 34 is insufficient, the inserting part as a whole can be increased to a hardness target by a hardness change of the flexible tube 27 to obtain good inserting performance.
