Problems solved by technology

However, although endoscopic biopsy can effectively identify Barrett's esophagus, this method is invasive and brings great pain to patients. It is not suitable for patients with bleeding and bleeding tendencies, heart disease and abnormal general conditions. Use; endoscopic mucosal resection, often with massive bleeding, and a very high incidence of serious complications, mainly because Barrett's esophagus is limited to the mucosal layer, this treatment can severely damage the surrounding normal tissue

Embodiment Construction

[0017] Such as figure 1 As shown, the present invention provides an endoscopic system suitable for positioning and identifying Barrett's esophagus, including a white light source 1, a Ti:Sapphire mode-locked femtosecond laser 2, an optical fiber 3, an acousto-optic modulator 4, and a photonic crystal fiber 5 , endoscopic probe 6, dichroic mirror 7, image sensor 8, filter 9, detector 10 and computer control processing unit 11;

[0018] The light emitted by the white light source 1 is incident into the endoscopic probe 6 through the optical fiber 3, so as to reach the esophageal epithelium, and the generated reflected light signal is output from the endoscopic probe 6, and then passes through the two endoscopic probes. The phase chromatic mirror 7 guides the image sensor 8 for detection, and the image sensor 8 inputs the detected signal into the computer control processing unit 11 to obtain white light irradiation emission imaging 12, thereby realizing the positioning of esophag...

Abstract

The invention relates to an endoscopic system applicable to positioning and recognition of Barrett's esophagus. The endoscopic system is characterized by comprising a white light source, a Ti: sapphire mode-locked femtosecond laser, optical fibers, an acoustic optical modulator, photonic crystal fibers, an endoscope probe, a dichroscope, an imaging sensor, a filter, a detector and a computer control processing unit. The endoscopic system is reasonable in design, skillful in conception and provided with wide development prospect and great popularization significance.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an endoscope system suitable for positioning and identifying Barrett's esophagus. Background technique [0002] Barrett's esophagus is secondary to long-term gastroesophageal reflux, and the acid-resistant single-layer columnar epithelium gradually replaces the stratified squamous epithelium of the lower esophagus, with or without intestinalization. If Barrett's esophagus is accompanied by dysplasia, it can eventually lead to esophageal adenocarcinoma, so it is regarded as a precancerous lesion. The presence of high-grade dysplasia in Barrett's esophagus is a critical step before progression to invasive esophageal adenocarcinoma. The risk of esophageal adenocarcinoma in patients with Barrett's esophagus is 30-125 times that of the general population, and the mortality rate of esophageal cancer accounts for about 35.12% of malignant tumor deaths. Therefore, the detection and treat...
