Problems solved by technology

The set pressure when the balloon is fixed to the intestinal wall is set to a certain pressure suitable for the human intestine, but in the case of the large intestine with a large lumen diameter, the size of the balloon reaches the lumen but the pressure But it can't rise to the problem of setting pressure
[0011] Moreover, when connecting the air supply and suction tubes to the air bag air supply ports of the balloon endoscope and the cannula, there are cases where the tubes are connected incorrectly. possible

Embodiment Construction

[0049] Hereinafter, embodiments of the balloon endoscope of the present invention will be described in detail with reference to the drawings.

[0050] Fig. 1 is a system configuration diagram of an endoscope device composed of a balloon-type endoscope and a balloon control device according to the present invention.

[0051] The endoscope device shown in this figure has a double balloon endoscope composed of a balloon endoscope 10 and a cannula 50 and a balloon control device 100 .

[0052] The balloon endoscope 10 is an electronic endoscope provided with an objective optical system 76 (refer to FIG. 3 ) and an imaging device (CCD) at the front end of the insertion portion 12. The observed image through the objective optical system 76 is imaged by the CCD, and Photoelectric conversion takes place here. The electrical signal representing the photoelectrically converted observation image is output to a processor (not shown) through the electric wires in the insertion part 12 and...

Abstract

The present invention relates to a bushing on the front end of which an inflatable bag is provided and the inflatable bag is connected with the inflatable bag control device through a pipe, and the inflatable bag control device is used for supplying and deflating air to enlarge or shrink the bag. The characteristic resides in that: the midway part of the pipe is connected with a liquid collecting tank.

Description

[0001] This application is a divisional application of the invention patent application whose application number is 200410043124.4, the application date is May 11, 2004, and the invention name is balloon endoscopy. technical field [0002] The invention relates to a cannula, in particular to a cannula with a freely expandable air bag arranged at the front end of an endoscope insertion part. Background technique [0003] A double-balloon endoscope is known as a device to replace the conventional small intestine endoscope. This double-balloon endoscope is composed of an endoscope with an air bag at the front end of the endoscope that can supply and suck air to the air bag, and a cannula as an insertion part that can be inserted into the endoscope. An airbag is provided and a cannula is configured to supply and suck air to and from the airbag (for example, Japanese Patent Application Laid-Open No. 51-11689 (page 2, FIG. 1 )). [0004] The air bag control device is connected to...
