Description

Wire/wireless combined endoscope for gastrointestinal diagnosis {Digestive system diagnostic wire/wireless endoscope}

The present invention relates to a wired/wireless composite endoscope for diagnosing the digestive tract, and the composite endoscope according to the present invention uses a flexible endoscope, which is a streamlined device, to effectively diagnose the esophagus, stomach, and large intestine, which are digestive organs, and uses a capsule endoscope detachable from the flexible endoscope. Accordingly, the present invention relates to a device capable of efficiently diagnosing the small intestine and large intestine while reducing battery consumption.

Currently, flexible endoscopes, a type of streamlined device, are being used for diagnosing the digestive organs, such as the esophagus, stomach, and large intestine. However, the existing streamlined flexible endoscope, which is inserted through the mouth or anus and inspected while adjusting, is difficult to operate, causes pain for the patient, and is difficult to move for a long period of time due to small diameter and long organs such as the small intestine. There was a problem in that it was difficult to detect diseases or lesions of patients related to the digestive system because it requires a procedure.

In order to solve this problem, a capsule-type endoscope has recently been developed and used. The capsule endoscope is a diagnostic device for diagnosing a capsule-shaped endoscope by swallowing it with the mouth and moving it inside the digestive system using peristalsis of the digestive system. Capsule endoscopes typically include a secondary solid-state electronic image sensor (e.g., CCD or CMOS image sensor) and an objective to image the mucous membrane of the gastrointestinal tract on the photosensitive surface of the image sensor, and a light emitting diode to illuminate the interior of the body to produce the image. (LED), an electronic circuit for taking images and transmitting them to an external recording device, an antenna for facilitating efficient image transmission, and a battery for supplying power for their functions.

Capsule endoscopes currently on the market are generally slightly larger than the size of coarse vitamin tablets, and when the electronic circuit of the capsule endoscope is activated, the patient swallows the capsule with a small amount of water. When a capsule endoscope enters the stomach, it typically stays for a certain period of time until it moves to the small intestine by gastric contraction. And, when the capsule endoscope enters the small intestine, the smooth muscle in the intestinal wall moves from the small intestine to the large intestine by normal peristaltic contraction. In addition, the capsule endoscope is generally discharged from a normal bowel movement within 12 to 48 hours.

However, the existing capsule endoscope can be moved to organs with a small diameter, such as the esophagus or small intestine, which are in close contact, but there is a problem in that it is difficult to move in the case of a curved part or an organ with a large diameter such as the large intestine. In addition, the capsule endoscope passes from the stomach to the small intestine through peristalsis, but unnecessary battery consumption occurs because of a long period of time, and the problem of not being able to diagnose the entire small intestine area may occur due to the limited battery capacity. In addition, although an active capsule endoscope driven by a magnetic field has recently been developed for the purpose of diagnosing the stomach, it is impossible to perform various treatment procedures in the stomach. there is a situation
