<P>PROBLEM TO BE SOLVED: To provide a distal end part of a safe side-viewing type endoscope, capable of removing a catheter only from a treatment instrument insertion channel of the endoscope using the catheter with a general cross-section shape so that the distal end of a guide wire is not pulled out of the pancreatic/bile duct, etc., without a risk of injury or blockage of the pancreatic/bile duct, or a risk that the catheter can not be removed from the pancreatic/bile duct. <P>SOLUTION: The distal end part of the endoscope is structured so that the guide wire 30 can be pressed and fixed on a wall part of a treatment instrument projection hole 3b by a treatment instrument raising piece 4 by drawing an operation wire 5 from the proximal end side 10 of an insertion part 1 with only the guide wire 30 projecting outward from the treatment instrument projection hole 3b. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
