Confocal endoscope imaging device

Abstract

The invention discloses a confocal endoscope imaging device. The device comprises an endoscopic objective lens, an endoscopic optical fiber bundle, a coupling objective lens, a first lens, a second lens, a high-speed scanning galvanometer, a laser, a dichroscope, a third lens, a pinhole, a photomultiplier tube and a computer. According to the device, confocal imaging and endoscopic imaging are combined, the endoscopic optical fiber bundle and the endoscopic objective lens are arranged, so that the device can extend into a digestive tract of a human body for detection, the advantages of high resolution of the confocal imaging and realization of an imaging effect of deep tissues can be fully utilized, so that lesion detection of the digestive tract can be realized on a cellular level, and the defects that the imaging depth of an existing clinical endoscope is generally small, and the imaging effect on deep tissue is poor are overcome. The invention further provides an optical fiber bundle adjusting frame which can conveniently adjust the position of a first end of the endoscopic optical fiber bundle, so that the endoscopic optical fiber bundle directly faces the coupling objective lens, and light beam coupling is achieved.

Description

technical field [0001] The invention relates to the field of confocal imaging, in particular to a confocal endoscope imaging device. Background technique [0002] Digestive tract tumors are characterized by high morbidity and high lethality, but the survival rate of early digestive tract tumors can reach more than 50% after cure. [0003] The precise pinhole of the confocal imaging device filters out stray light, and only the points on the focal plane of the sample participate in the imaging. It has the characteristics of high resolution and clear images, and can be used to observe the occurrence, development, curative effect and skin lesions of skin diseases. Observation of internal organization cannot be achieved. For example, Chinese patent CN202022435855.0 discloses a reflective confocal imaging device, which adopts the principle of confocal imaging and can be used for observation of skin diseases. However, it cannot be used for the detection of internal tissues, such ...

However, it cannot be used for the detection of internal tissues, such as the digestive tract

[0004] At present, endoscopes are usually used clinically to detect internal tissues such as digestive tract tumors, but the imaging depth of endoscopes is generally small, and the imaging effect on deep tissues is poor

[0005] Therefore, using confocal imaging has the characteristics of high resolution and the ability to achieve imaging effects in deep tissues. Applying confocal imaging to endoscopic imaging will be of great significance for the detection of internal tissues of the human body, such as the detection of gastrointestinal lesions, but there is currently a lack of reliable plan
