<P>PROBLEM TO BE SOLVED: To provide an injection needle for an endoscope in which it is possible to easily adjust and confirm a protruding length of a puncturing needle and to easily check whether or not the puncturing needle protrudes from an outer tubular catheter. <P>SOLUTION: The needle for the endoscope has a inner tubular catheter to whose distal end the puncturing needle is attached and to whose proximal end an inner grip to whose distal end a syringe is connected is attached, the outer tubular catheter having a lumen movable back and forth in a longitudinal direction of the inner tubular catheter, a protruding length adjusting grip attached to the proximal end of the outer tubular catheter, comprising an outer grip having a lumen in which the inner grip can move back and forth in a longitudinal direction, and arranged coaxially with the center axis of the inner grip and outer grip, and rotatable around the axis, and a stroke adjusting mechanism capable of adjusting the stroke of the inner grip moving interlockingly with the above protruding length adjusting grip. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
