Radiographically visualized enteroscopic guiding device

Abstract

The invention discloses an enteroscope guiding device capable of developing under radioactive rays. The enteroscope guiding device comprises a soft and smooth guide wire, wherein a guiding body is arranged at the front end of the guide wire; the rear end of the guide wire is branched to form a first branch wire and a second branch wire, the first branch wire is connected with an air bag allowing air injection through a syringe needle, and a connection structure used for being connected with an external connection wire is arranged at the tail end of the second branch wire; the guide wire is towed by the guiding body to penetrate an alimentary canal and clearly displays the complete traveling mode of the small intestine under radioactive rays, so that an operator can comprehensively learn about traveling of the small intestine of each patient before an operation; the traveling direction of the small intestine at the front end can be accurately judged during examination; the distance between the front end of an endoscope and the ileocecal valve is accurately judged; and the guide wire can enter a biopsy duct to guide operation of an enteroscope. Therefore, the operation success rate and efficiency of the enteroscope are improved to a great extent, the technical difficulty of the enteroscope is greatly reduced, and a novel enteroscope guided by the guide wire can be developed accordingly.

Description

technical field [0001] The present invention relates to a guide device for small intestine, in particular to a guide device for small intestine that can be visualized under radiation. It guides the completion of the small intestine endoscopic examination, and the operation is simple and easy, so that the technical difficulty of the small intestine endoscopy is greatly reduced, and the level and success rate of the small intestine endoscopic examination are improved. Background technique [0002] The small intestine is the longest organ in the human digestive system, with a total length of about 5-7 meters in adults, accounting for 75% of the total length of the digestive tract. The upper end of the small intestine connects to the gastric pylorus, and the lower end connects to the colon in the right iliac fossa, and can be divided into three parts: the duodenum, jejunum, and ileum. Because the small intestine is long and free, twists and turns and overlaps, is located in the...

Problems solved by technology

However, the operation technique of the existing enteroscopy is complicated, and the probability of seeing the entire small intestine in one-time inspection is extremely low. Many patients still cannot inspect the entire small intestine through bilateral endoscopy.

[0004] Our research on autopsy found that there are great variations in the course of the human small intestine. If you do not know enough about the course of the small intestine, it is easy to form a loop during the process of entering the microscope. Therefore, the success rate of the whole small intestine examination through the mouth is not high, and Compared with gastroscopy and colonoscopy, the course and structure of the small intestine vary greatly, and doctors cannot predict the course of the small intestine before and during the examination, nor can they know the distance between the endoscope and the ileocecal valve during the operation, so there is a huge risk. blindness
