A kind of gastrointestinal endoscope biopsy extracting device

Abstract

The invention discloses a biopsy extraction device for gastrointestinal endoscopy. The biopsy extraction device for gastrointestinal endoscopy can greatly improve the convenience of extracting biopsy tissue for gastrointestinal endoscopy. Realize separate extraction of multiple parts, no crossover problem, and accurate positioning at the same time. At the same time, the extraction tooth net on the extraction head is used for extraction, and the extraction will not cause major damage to the patient's tissue. At the same time , the extraction head is rotated during extraction, which can quickly realize the extraction of the parts that need to be extracted, and can also cooperate with the fixed extraction head and the sliding extraction head to perform large-scale tissue biopsy extraction. The present invention also sets The direction control component can realize the extraction of the required part of the patient very quickly and accurately.

Description

technical field [0001] The invention relates to a gastroenteroscope biopsy extracting device, which belongs to the technical field of gastroenteroscope biopsy. Background technique [0002] At present, gastrointestinal endoscopy is to use a black plastic tube with a diameter of about one centimeter to wrap the light-guiding fiber. The strong light emitted by the light source can turn the light through the light guide fiber, allowing the doctor to clearly observe the health status of various parts of the upper digestive tract from the other end. When necessary, the small hole on the gastroscope can be inserted into the clip for biopsy , Gastrointestinal endoscopy and biopsy are to determine whether there is cancer, and to make a clear diagnosis as soon as possible. Whether it is gastric cancer depends on the report of the test results. Likewise, a colonoscopy is performed through the anus and into the rectum until it reaches the large intestine, allowing the doctor to observ...

Problems solved by technology

[0003] For gastrointestinal endoscopy, when it is necessary to biopsy the lesion, it needs to be sliced. Most of the current slices are clamped with clips. This method is less efficient, and when multiple biopsy sites are required When picking, the clip is prone to cross-infection, which affects the accuracy of biopsy. At the same time, when the clip is picked, it will seriously damage the local part of the gastrointestinal tract, causing discomfort to the patient
