Insertion auxiliary tool for endoscope

Abstract

The present invention provides an insertion auxiliary tool for an endoscope, being able to educe an insertion part of an endoscope from the side wall opening of a tubular body smoothly and easily. The invention provides an insertion auxiliary tool (60) for an endoscope for making an insertion part (12) of an endoscope (10) penetrated and educing the insertion part. The insertion auxiliary tool (60) comprises a soft tube (64) of an insertion path (66) for penetrating the insertion part (12), a side wall opening part (64) which is educed from the front end of the insertion part (12) of the insertion path (66) and is arranged at the front end side of a side wall part (65) of the soft tube (64), and an identification (70) which represents the position of the circumferential direction of the soft tube of a side wall opening (68), wherein the inner surface of the soft tube (64) is formed along the axial direction of the soft tube.

Description

technical field [0001] The present invention relates to an insertion aid for an endoscope, and more particularly to an insertion aid for an endoscope used when inserting an insertion portion of an endoscope into a narrow lumen such as a biliary tract or a pancreatic duct. Background technique [0002] In recent years, in the medical field, for example, endoscopes have been widely used in the examination or treatment of biliary and pancreatic diseases such as biliary tract cancer, pancreatic cancer, cholelithiasis, and common bile duct stones. These have the advantage of being less invasive and less burdensome to patients than conventional surgical treatments. [0003] As one of the above-mentioned examination methods and treatment methods, for example, ERCP (Endscopic Retrograde Cholangio-Pancreatography: Endoscopic Retrograde Cholangio-Pancreatography) is known. ERCP is a diagnostic method in which a contrast agent is injected into the biliary tract or pancreatic duct usin...

Problems solved by technology

[0011] However, in the conventional insertion aids for endoscopes disclosed in Patent Documents 1 and 2, in a state where the side wall opening does not enter the field of view of the endoscope, it is impossible to grasp the relationship between the side wall opening of the cylindrical body and the endoscope. Due to the positional relationship in the circumferential direction of the cylindrical body of the insertion part, it is difficult to align the opening of the side wall with the desired position in the body cavity, so that the front end of the insertion part cannot be easily drawn out from the opening of the side wall.
