A microtome for embedding paraffin block of esophageal cancer pathological tissue

Abstract

The invention relates to a slicer used for embedding paraffin blocks of pathological tissues of esophagus cancer. The slicer comprises a round shell, displacement devices, cutting devices and a lifting device; the round shell comprises transmission inner cavities and cutting slots; each displacement device comprises a worm assembly, a worm gear assembly, a drive screw and a nut assembly; and eachcutting device comprises an input cone pulley assembly, a telescopic transmission shaft and a cutting tool bit. The slicer used for the embedding paraffin blocks of the pathological tissues of the esophagus cancer is reasonable in structure and simple to operate, and is capable of simultaneously performing installation and synchronous cutting on the multiple embedding paraffin blocks, and then, continued making is facilitated to finally form pathological slices, and the check on a patient with the esophagus cancer is facilitated; and the slicer is capable of precisely regulating the cut thickness of each embedding paraffin block.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a slicer for embedding wax blocks of pathological tissues of esophageal cancer. Background technique [0002] Pathological slides are often required in the diagnosis of esophageal cancer. First, take a lesion tissue of a certain size, and make a pathological section by histopathological method (usually the lesion tissue is embedded in a paraffin block, cut into thin slices with a microtome, and then stained with hematoxylin-eosin (H-E)]. Lesions were further examined with a microscope. The occurrence and development of the lesion, and finally make a pathological diagnosis. [0003] In the prior art, the embedding wax blocks of pathological tissues are sliced ​​by a microtome, but there is a problem that only a single embedding wax block can be cut, and multiple embedding wax blocks cannot be cut at the same time; and the cutting accuracy is limited, and the cutting thickness ...
