Transmission-type fluorescence imaging equipment capable of detecting deep lymphatic vessels and lymph nodes

Abstract

The invention relates to the field of medical fluorescence detection, in particular to transmission-type fluorescence imaging equipment capable of detecting deep lymphatic vessels and lymph nodes. The transmission-type fluorescence imaging equipment can improve the illuminance of a detection area through a split-type external light source so as to optimize the fluorescence detection effect. The transmission-type fluorescence imaging equipment capable of detecting deep lymphatic vessels and lymph nodes comprises a detection light source and a probe body, wherein the detection light source comprises a light source body, the light source body is of a rod-shaped structure, one end of the light source body is provided with a light-emitting body, and the other end of the light source body is connected with a power line; a clip is arranged on the probe body; a plurality of positions on the light source body can be detachably connected with the clip; and the detection light source is not directly integrated in the probe, so that the probe is more flexible in structural arrangement and convenient to adapt to various requirements.

Description

technical field [0001] The invention relates to the field of medical fluorescence detection, in particular to a transmission fluorescence imaging device capable of detecting deep lymphatic vessels and lymph nodes. Background technique [0002] Fluorescence detection is a natural luminescence reaction, through the reaction of luciferase and ATP, it can detect human cells, bacteria, mold, and food residues. During the working process of the fluorescence detection equipment, the target needs to be irradiated by the fluorescence detection light source, and then the fluorescence reaction is collected by the imaging equipment. [0003] The positions of sentinel lymph nodes and deep lymphatic vessels in the human body are not fixed, and they tend to be buried deep under the skin of the human body. When using fluorescence detection to find relevant parts, it is usually impossible to penetrate human tissues due to insufficient illumination, resulting in fluorescence detection. less ...

AI Technical Summary

Problems solved by technology

However, in this solution, since the light source is integrated into the handheld device, due to the limited volume of the handheld device, the volume of the handheld device cannot be too large in the medical inspection work, resulting in a small illuminant of the light source, resulting in insufficient illuminance problems, and the illumination cannot be adjusted according to the needs, which will eventually affect the fluorescence detection effect

At present, only superficial lymphatic vessels and lymph nodes close to the skin can be seen in fluorescein imaging equipment. This is because the usual fluorescein imaging equipment adopts the excitation light reflection fluorescence imaging mode. Since the human body tissue is very thick, the excitation light is difficult. Illuminates from behind and penetrates tissue

Therefore, there is currently no clinically available transmission fluorescein imaging equipment.
