Abstract

A video acquisition system for a narrow cavitary space based on a microprobe structure, comprising an intelligent computer aided diagnosis system and a microprobe (104). The intelligent computer aided diagnosis system trains a large number of pictures of different lesions using a deep learning technique, and can complete auxiliary diagnosis of different common lesions in the colonoscopy process. The microprobe (104) is provided at the tail end of a clamp channel (103) for taking samples from tissues. When the intelligent computer aided diagnosis system determines that some of the tissues taken out are pathological tissues, the microprobe (104) is retracted from the clamp channel (103) and carries the pathological tissues out of a colonoscope (102) duct from the clamp channel (103). When it is determined that the some of the tissues taken out are normal intestinal tissues or intestinal debris, the microprobe (104) discharges the tissues and is not retracted. The video acquisition system can reduce the probability of missed detection of lesions.

Description

Video acquisition system based on micro-probe structure in narrow space of cavity

Technical field

The present invention relates to the technical field of lesion detection based on microprobes, in particular to a video acquisition system based on a microprobe structure in a narrow space of a cavity.

Background technique

Colon polyps are a common disease of the digestive system. Many patients undergo colonoscopy due to symptoms such as abdominal pain and blood in the stool, and are diagnosed as colon polyps under endoscopy. Colon cancer is one of the common digestive system tumors in my country. With the continuous improvement of people's living standards, the incidence of colon cancer is increasing. Electronic enteroscopy is currently the most important inspection method for colon polyps, and it is also the main method of endoscopic treatment of colon polyps. The number, diameter, growth pattern, location of polyps under the microscope are related to the pathology of polyps, and the focus on observation during the examination is beneficial to the diagnosis and treatment of colon polyps.

In the process of colonoscopy, the main pathological analysis method for polyps, tumors and other lesions is to use surgical forceps to remove the intestine and then send a biopsy to further analyze the pathological nature of the tumor, so as to determine the severity and risk of the patient . During the inspection, there are parts that are not easy to observe, such as narrow cavities and difficult to unfold folds. The current colonoscopy surgery has missed diagnosis. Part of the reason is that it is difficult to observe and sample and analyze these parts.

Summary of the invention

In view of the above-mentioned technical problems in the prior art, the purpose of the present invention is to provide a micro-probe structure-based video acquisition system in a narrow space with a cavity.

In order to achieve the objective of the present invention, the present invention provides a micro-probe structure-based video acquisition system in a narrow space of a cavity, including:

Intelligent Computer Aided Diagnosis (CAD) system and micro probes,

The CAD system uses deep learning technology to train a large number of pictures of various lesions, and the CAD system can complete the auxiliary diagnosis of various common lesions during the colonoscopy operation;

The microprobe is arranged at the end of the clamp channel, and the microprobe is used to sample from the tissue;

The CAD system is used to identify whether the removed part of the tissue is likely to have lesions through image recognition technology. When the CAD system determines that the removed part of the tissue is a diseased tissue, the probe retracts the clamp channel and carries the diseased tissue out of the clamp channel Colonoscopy pipeline; when the CAD system determines that the removed part of the tissue is normal intestinal tissue or intestinal debris, the probe will expel it and not retract it.

Compared with the prior art, the beneficial effect of the present invention is that the present invention proposes a micro-probe structure-based video acquisition system for narrow cavity space, which can use the micro-probe to remove the narrow space from the cavity during colonoscopy. Part of the tissue is taken out in a small space, so that it can be further judged whether there is a disease in the corresponding tissue in the analysis field, so as to determine the patient's disease more quickly and conveniently, and reduce the probability of missed detection of the disease. The tissues that may be diseased can be removed by the colonoscopy forceps using micro-probes for further examination and analysis, and normal tissues are placed in the intestinal lumen without further examination.

Step 201: Take the next step when encountering parts that are not easy to observe, such as narrow cavities and hard-to-open folds, during the inspection;

Step 202, use the microprobe to sample, extend the microprobe from the clamp channel and sample at a narrow part;

Step 203: Use an intelligent assisted diagnosis CAD system and use image recognition technology to identify whether the removed part of the tissue is likely to cause disease;
