Abstract
Description
Technical Field
[0001] The utility model relates to a medical device, in particular to an insertion part of a gastroenteroscopy. Background Art
[0002] Gastroenteroscopy is a general term for gastroscopy and colonoscopy. Gastroscopy is mainly used in medical treatment to check whether there are lesions in the patient's esophagus, stomach, duodenum and other organs. Colonoscopy is mainly used to check whether there are lesions in the rectum, colon, cecum and terminal ileum.
[0003] Specifically, a gastroenteroscope includes an inspection part for doctors to operate and inspect and an insertion part for inserting into the human body. In addition to the probe fixed at the end to realize the function of direct inspection, the insertion part is also provided with a clamp channel, so that it has the function of collecting samples for biopsy at specific parts. However, the existing gastroenteroscopes have the following disadvantages when performing microbial sampling: both gastroscopes and colonoscopes can check the health status of multiple organs. When the gastroenteroscope needs to sample organs with a relatively long depth (such as using a gastroscope to sample the environmental contents of the duodenum), the end of the insertion part will be contaminated when passing through other organs (such as the gastroscope passing through the esophagus and stomach). Contamination means that the end of the clamp channel will passively collect secretions from other organs (such as the esophagus and stomach), thereby making the composition of the collected materials in the clamp channel complex, and it is impossible to accurately collect the environmental contents of a specific organ, affecting subsequent tests and research. Summary of the invention
[0004] Purpose of the utility model: The purpose of the utility model is to provide an insertion portion of a gastroenteroscope that can accurately collect secretions from specific organs.
[0005] Technical solution: The insertion part of a gastroenteroscopy described in the utility model includes an insertion hose for inserting into the human body, a clamp channel is provided inside the insertion hose, the insertion end of the clamp channel passes through the insertion end of the insertion hose, and a detachable sealing plug is provided at the insertion end of the clamp channel. The clamp channel is a common term in the industry, and is also called an equipment pipeline in some manuals. It refers to a channel provided in the insertion hose for doctors to sample the environmental contents of the organ.
[0006] Furthermore, the fixing ring is detachably connected to the outer wall of the insertion hose, the fixing ring is arranged near the insertion end of the insertion hose, and the fixing ring is fixedly connected to the closing plug via a connecting line.
[0007] Furthermore, the closing plug may be in the shape of a truncated cone or a cylinder; the closing plug may also be in the shape of a T, that is, the closing plug includes an extending plug column, and a closing cover is provided at one end of the deep plug for closing the clamp channel, and the diameter of the closing cover is larger than the diameter of the clamp channel.
[0008] Furthermore, the closure plug is flexible.
[0009] Furthermore, it also includes a sampling brush, which is slidably connected to the clamp channel. The outer wall of the sampling brush is provided with a plurality of bristles that abut against the clamp channel. The tail of the insertion hose is provided with an insertion port for the sampling brush to be inserted.
[0010] Furthermore, a plurality of light sources are evenly distributed on the insertion end of the insertion hose, and the light sources are used to emit light to facilitate the probe to illuminate the internal conditions of the organ.
[0011] Furthermore, a probe is fixedly arranged at the insertion end of the insertion hose.
[0012] Beneficial effects: Compared with the prior art, the utility model has the following advantages: before the insertion hose of the gastroenteroscope is inserted into the human body, the medical staff uses a sealing plug to seal the insertion end of the clamp channel, so that before reaching the designated position, the insertion end of the clamp channel will not contact the secretions of other organs. After reaching the designated position, the sampling brush is inserted into the clamp channel and the sealing plug is poked outward, and the insertion end of the clamp channel is opened to collect the secretions at the corresponding position.
