Fluorophor positioning device for jointly positioning and excising diseased region by gastrointestinal endoscope and peritoneoscope

Abstract

The invention relates to a fluorophor positioning device for jointly positioning and excising a diseased region by a gastrointestinal endoscope and a peritoneoscope, which is characterized in that the device is formed by a fluorophor base layer (4), a fluorophor layer (3), a protection layer (2) and a connecting, positioning and fixing mechanism, wherein the fluorophor layer (3) is arranged on the periphery of the fluorophor base layer (4); the protection layer (2) is arranged on the periphery of the fluorophor layer (3); the connecting, positioning and fixing mechanism is arranged on a horizontal central line of the fluorophor base layer (4) and the fluorophor layer (3); the fluorophor base layer (4) and the fluorophor layer (3) are designed to be oval spheres; and a through hole of a fine and long shaft (7) capable of penetrating through the connecting, positioning and fixing mechanism is arranged in the direction of a long axis of the oval sphere of the fluorophor base layer (4), and the size of the oval sphere is 1 cm*3 cm (the long axis*a short axis). The technology has the characteristics of simple structure, convenience for use, and capability of effectively solving the problem of accurately and timely positioning a focus in a gastrointestinal tract operation and the like.

Description

[0001] 1. Fields: [0002] The invention relates to the technical field of medical devices, in particular to a fluorescent body positioning device for combining gastroenteroscope and laparoscope for positioning and resecting lesion parts. 2. Background technology: [0003] At present, laparoscopes and endoscopes, which are widely used in hospitals, are commonly used medical devices in gastrointestinal tumor surgery. In recent years, the combination of laparoscopy and endoscopy has attracted more and more attention. For patients with gastric stromal tumors, polyps or gastric bleeding that require surgery, the lesions often grow into the cavity, and there may be only raised changes outside the cavity. It is difficult to accurately locate and provide reference for surgical resection through visual observation through laparoscopy. For patients with colorectal polyps or early cancers, those with large diameters, suspected malignant transformation, or polyps that are difficult to o...
