<P>PROBLEM TO BE SOLVED: To provide an injection needle for an endoscope which facilitates the recognition of the state whether a puncture needle is housed in a lumen of an outer cylinder catheter or is protruded from the distal end of the outer cylinder catheter. <P>SOLUTION: The injection needle for the endoscope comprises the puncture needle at the distal end, an inner cylinder catheter with an inner grip having the proximal end where a syringe is connected, the outer cylinder catheter with the lumen in which the inner cylinder catheter moves back and forth in the longitudinal direction, and an outer grip which is attached to the proximal end of the outer cylinder catheter and has a lumen in which the inner grip moves back and forth in the longitudinal direction. The injection needle for the endoscope is provided with a display, which shows that the puncture needle is protruded from the distal end of the outer cylinder catheter, at a part on the outer periphery of the inner grip, and a window or a groove is provided at a part on the outer periphery of the outer grip. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
