JPH11290263A - Endoscope mounting balloon used for mounting digestive tract endoscopy, sliding tube with balloon, and use thereof - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent the tip of an endoscope from coming off at a time when an extra flexion or warp occurring in the endoscope to be smoothed by mounting balloons near the tip of the endoscope and fixing temporarily the balloons to the intestine by inflating them. SOLUTION: An endoscope 1 is inserted into a sliding tube 5, and with their balloons 2, 6 kept collapsed, the endoscope 1 is inserted into the intestine. And then, the endoscope 1 is inserted deeply into the intestine and the balloon 2 for mounting on the endoscope is inflated and fixed to the intestine. And then the sliding tube 5 is inserted deeply into the intestine following the endoscope 1 and brought near the tip of the endoscope 1, and the balloon 6 at the tip of the sliding tube 5 is inflated and fixed to the intestine. The endoscope 1 is advanced more deeply beyond the fixation point of the sliding tube 5 and the balloon 2 is inflated again and so on, thereby performing the observation of a deep part of the digestive tract.

実用化には至っていない。2. Description of the Related Art The conventional endoscope insertion technique is basically to push the endoscope in. The small intestine endoscope is also of the push type. However, the endoscope is complicated due to complicated bending of the intestinal tract. The force is not easily transmitted to the distal end and insertion into the deep part is difficult, and the subject suffers greatly. This method can be observed at most up to about 50 cm above the jejunum. As a method for endoscopic observation to a deeper part, a sonde method, a rope method
The way method has been devised, but has hardly been put to practical use because the inspection is complicated and takes a long time, and the observation cannot be performed sufficiently.

が出来ないという問題点があった。In the conventional push type endoscope, if the endoscope is pulled back in order to extend the excessive bending or bending caused by the deep insertion, the end of the endoscope also comes off. Therefore, there was a problem that bending deflection could not be obtained and deep insertion was not possible.

が付いたスライディングチューブを用いるのである。In order to solve the above-mentioned problems, in the present invention, a balloon is first mounted near the end of the endoscope. By inflating it and temporarily fixing it to the intestinal tract, the tip of the endoscope is prevented from coming off when the extra bending or bending created in the endoscope is extended. Then, a sliding tube with a balloon at the tip is used to keep the form of the intestinal tract, which is almost straightened by taking excess bending, and to prevent it from coming off.

At first, the insertion of the endoscope is started with both balloons collapsed. When the endoscope is inserted as deep as possible, the balloon of claim 1 is inflated and fixed to the intestinal tract so that the end of the endoscope does not come off. Take the excess deflection, straighten the endoscope as much as possible, insert the sliding tube of claim 2 along the endoscope deeply, and hold the tip of the sliding tube to near the end of the endoscope. . Here, the balloon at the tip of the sliding tube is inflated and fixed to the intestinal tract. Next, the balloon of claim 1 is collapsed, and the endoscope is advanced as far as possible from the fixing point of the sliding tube of claim 2 as a second fixing point, and the balloon of claim 1 is inflated again. By repeating the above operation, the endoscopic observation of the deep digestive tract is advanced.

Endoscopy can be performed. Until now, endoscopic observation has been extremely difficult, and a black box
It is considered that observation of the lumen of the deep small intestine, which has been called, can be performed over almost the entire area.
