Abstract

An assisting tool (12) combined with a nasal endoscope (11) is provided. The assisting tool (12) has an insertion section (35) insertable through the other nostril as the endoscope (11). The assisting tool (12) has an attachment portion (36) attachable to a forceps inlet port (19) of the endoscope (11). The attachment portion (36) includes a forceps inlet port (42) and a bifurcated connecting channel for connecting the forceps inlet port (42) to both forceps channels in the assisting tool (12) and the endoscope (11). The insertion sections (16, 35) have fastening members (23, 24, 40, 41) to fasten these insertion sections together. The insertion sections (16, 35) are inserted through different nostrils and fastened together with the fastening members (23, 24, 40, 41), as their front faces are aligned in the area around the posterior nares, and then advanced together from the esophagus to the stomach.

Description

technical field [0001] The present invention relates to an endoscope system for visualizing the inside of a patient's body, a method of using the endoscope system, and an assisting tool and an adapter to be used with the endoscope system. Background technique [0002] A nasal endoscope is a device having an elastic and tubular insertion portion to be inserted through a nostril for visual observation of the inside of a patient's body (for example, see Japanese Laid-Open Patent Publication No. 2006-68030 and No. 2007-61377 ). Since such an insertion portion can enter into the esophagus without touching the base of the tongue, the nasal endoscope puts little physical burden on the patient, including less vomiting reaction and nausea than an oral endoscope whose insertion portion is inserted through the patient's mouth. There are other advantages in that nasal endoscopes require less anesthetic than oral endoscopes and allow talking to the patient under examination and allowing...
