Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of microscopic imaging, in particular to a microscopic imaging device for pathological sections. Background Art
[0002] Pathological examination is a pathological morphological method used to examine pathological changes in organs, tissues or cells of the body. In order to explore the disease process of organs, tissues or cells, a certain pathological morphological examination method can be used to examine the lesions that occur in them, explore the causes, pathogenesis, and development of the lesions, and finally make a pathological diagnosis. The pathological morphological examination method first observes the pathological changes of the gross specimen, then cuts a certain size of the lesion tissue, uses the pathological histological method to make a pathological section, and further examines the lesion under a microscope.
[0003] After searching the publication (announcement) number: CN 211603708 U, a new type of microscopic imager is disclosed, including an eyepiece, a lens barrel, a converter, an objective lens, a stage, a reflector, a mirror arm, a mirror column and a mirror seat. A condenser is arranged around the stage. The mirror arm is connected to the mirror column through an axis. The axis is fixed on the mirror arm. The axis passes through the mounting hole of the mirror column and then a sealing ring is put on. The end of the axis is provided with a thread and fastened with a fastener; a fastening rod is arranged on the fastener. The utility model reduces the interference of the external light source on the measured target through the condenser, improves the focusing accuracy, and makes the light of the reflector more concentrated, reducing visual fatigue. The rotation is achieved by connecting the axis and the mirror column. The structure is simple and effective. The stage is rotated to the desired position by rotating the axis.
[0004] Although the above scheme reduces the interference of external light sources on the target and improves the focusing accuracy through the condenser, the field of view diameter of the microscope is at the millimeter or sub-millimeter level, which makes it impossible to complete the one-time imaging of tissue sections. In order to observe and compare different areas, medical staff must repeatedly move the field of view. For this reason, we propose a microscopic imaging device for pathological sections.
