Digestive system inspection device

Abstract

The invention relates to the technical field of medical instruments, in particular to a digestive system inspection device which comprises a capsule endoscopy and a feeder, the capsule endoscopy comprises a camera shooting end as a tail end, and a block capable of being attracted by a magnet is arranged in the tail end; the feeder comprises a conveying pipe, a connector and a controller, and the connector and the controller are arranged at the two ends of the conveying pipe respectively; an electromagnet is arranged on the connector, and the controller controls the electromagnet to work; and the diameter of the conveying pipe and the diameter of the connector are smaller than the diameter of the capsule endoscopy. Through the arrangement of the electromagnet on the connector and the block which is arranged at the tail end of the capsule endoscopy and can be attracted by the magnet, electromagnetic attraction and separation can be achieved, picking and releasing are convenient, the adopted electromagnet is matched with the block, the diameter of the capsule endoscopy serves as the working diameter of the device, the pain of a patient and the operation difficulty of an operation doctor are reduced, the trafficability of the device in a digestive system is improved, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a digestive system inspection device. Background technique [0002] The small intestine is the lumen of the digestive tract connecting the pylorus and the ileocecal valve. Except for the part above the descending duodenum and the terminal ileum, which can be subjected to routine gastroscopy and colonoscopy, the other parts are the most difficult to examine in the entire gastrointestinal tract. Due to the long length of the small intestine (3.35-7.85m), the free intraperitoneal and bound by the mesentery to form multiple compound intestinal loops, the traditional inspection techniques are greatly limited. Many methods of small intestine examination, such as X-ray small intestine barium meal examination, enteroscopy, radionuclide scanning, and arteriography, all have low diagnostic positive rate, inaccurate positioning and qualitative identification, great pain for patients...

AI Technical Summary

Problems solved by technology

Although capsule endoscopy has high diagnostic value for diseases such as small intestinal inflammation and bleeding, it also has many defects. One of the more common shortcomings is that capsule endoscopy is greatly affected by the movement (peristalsis) of the stomach and small intestine after swallowing, while Battery life is limited

When the peristalsis of the stomach or esophagus is slow or there is obstruction, the capsule will stay in the stomach or esophagus for a long time, and cannot enter the small intestine or the battery energy has been consumed too much when entering the small intestine, and it is no longer possible to take pictures of the entire small intestine. Missed diagnosis due to inability to complete the examination

Another less common disadvantage is that capsule endoscopy is still too bulky compared to clinically administered capsule-shaped pills, and very few patients (mainly young patients) cannot swallow due to fear or throat muscle spasm. Into the esophagus, making the test impossible

[0003] When the above situation occurs, it is necessary for the physician to send the capsule endoscope into the descending duodenum with the help of gastroscope and endoscope snare (or mesh basket), which increases the pain of the patient, is time-consuming, labor-intensive, and may unsuccessful

In addition, capsule endoscopy is currently very expensive. Once the inspection is unsuccessful, it will easily lead to conflicts among patients, hospitals, distributors and manufacturers.

[0004] In view of the above problems, relevant patent literature has reported that a special pusher can be used to deliver the capsule endoscope to the duodenum with the assistance of a gastroscope. It is more complicated, and it is only for patients who cannot swallow capsule endoscopes smoothly. As mentioned above, the shell of capsule endoscopes is made of smooth polymer materials. In clinical practice, most patients can swallow them smoothly and enter the 12 the duodenum, so in adults, the routine use of a pusher to enter the duodenum is not required

However, the shell of the capsule endoscope is very smooth, and it is even more difficult to take the retained capsule endoscope out of the body through the gastroscope than directly into the duodenum, so the practical value of the pusher is very limited

At present, clinically, for capsule endoscopy that stays in the esophagus and stomach, under the guidance of a gastroscope, a snare or a basket is used to trap the capsule and send it to the duodenum. Smooth, the snare or basket is not easy to net the capsule, even after the net is caught, it can only net the middle part of the capsule endoscope shell horizontally. The resistance to passing through the pylorus is very high, and the steel wire of the snare or the basket can not resist the resistance and bend, resulting in the failure of the capsule endoscope to pass through the pylorus or slippage. Therefore, gastroscopy doctors need to spend a lot of time and energy to complete this work, and the pressure is very high during the operation. At the same time, the gastroscope stays in the patient's body for a long time, which increases the pain and risk of the patient

[0005] CN201210430495.2 discloses a capsule endoscope feeder, the feeding device clamps or picks up the capsule endoscope through the large end of the connecting sleeve and sends it to a preset position for delivery, but the technical solution The pick-up end is relatively large, and the large end is clamped by the annular clamping structure of the capsule endoscope. It will cause pain and inconvenience to the patient
