Lymph node detector

Abstract

A sentinel lymph mode detector (1) comprises an exciting light source unit (2) for applying an exciting light (10) to an organism observed portion (20) including a sentinel lymph node (21) near a tumor into which a fluorescent dye capable of emitting fluorescence is injected, an optical filer (3) through which a florescence image (11) passes, an imaging unit (4) provided integrally with the exciting light source unit (2) and adapted for capturing the fluorescence image (11) having passed through the optical filter (3), an adjusting unit (5) for adjusting the captured observation image, and an image display unit (6) for displaying the adjusted observation image. The adjusting unit (5) adjusts at least one of the luminance and contrast of the observation image. The lymph node detector is simple in structure and easy to handle, and creates a favorable image.

Description

technical field [0001] The present invention relates to a lymph node detection device for detecting a lymph node such as a sentinel lymph node using a fluorescent image emitted from a fluorescent dye. Background technique [0002] The so-called sentinel lymph node is a lymph node with the highest possibility of metastasis of cancer cells that first reach cancer cells from the tumor through the lymph flow. Therefore, if the sentinel lymph node can be correctly identified, and no metastasis of cancer cells is found there, it can be considered that there is no metastasis to other internal organs. As a result, it can be expected that the physical and mental burden on the patient will be greatly reduced, and the treatment cost will be reduced due to the omission of excision surgery. [0003] As methods for detecting sentinel lymph nodes, the dye method and the RI (radioisotope) method are mainly known. In the dye method, for example, a blue dye such as sulfonated indigo is inje...

Problems solved by technology

[0008] In addition, in the sentinel lymph node detection device using the above-mentioned conventional fluorescent dye, although there is no risk of being exposed, there is a problem that it is difficult to operate in the medical field due to the complicated structure of the device, or neither of them can be obtained well. problems with images, etc.
