Embodiment Construction

[0056] Hereinafter, preferred embodiments of the insertion aid according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a system configuration diagram showing an endoscope apparatus to which an insertion aid according to the present invention is applied. As shown in FIG. 1 , the endoscope device is mainly composed of an endoscope 10 , an insertion aid 60 , and a balloon control device 100 .

[0057] The endoscope 10 includes a portable operation unit 14 and an insertion unit 12 connected to the portable operation unit 14 and inserted into the body. A universal cable 16 is connected to the portable operation unit 14 , and an LG connector 18 is provided at the tip of the universal cable 16 . The LG connector 18 is detachably connected to the light source device 20, whereby the illumination light is sent to the illumination optical system 54 described below (refer to figure 2 ). In addition, an electrical connector 24 is connecte...

Abstract

An insertion assisting tool (60) is provided and includes an insertion path (70) in which the insertion portion of an endoscope is inserted and a tube for fluid (72,74) which is formed along the axial direction at the tubular wall portion of the insertion path. The insertion path has a circular shape in its section orthogonal to the axial direction. The tube is configured in a manner that the sectional shape thereof along the axial direction is longer in the circumferential direction than the radial direction.

Description

technical field [0001] The present invention relates to an insertion aid, in particular to a medical insertion aid for assisting the insertion of an endoscope for observing the small intestine or large intestine into the body. It also relates to an insertion aid for an endoscope that includes a balloon on the outer peripheral portion of the distal end while the insertion portion of the endoscope is inserted. Background technique [0002] The deep digestive tract such as the small intestine or large intestine is complicated to bend, and it is difficult to transmit the force to the front end of the insertion part of the endoscope just by pushing the insertion part of the endoscope, and it is difficult to insert deep. Therefore, a method of inserting an endoscope insertion portion into a body through a cylindrical insertion aid (also referred to as a cannula or a slide tube) is disclosed. According to this method, since the insertion part is guided by the insertion aid, the in...
