Problems solved by technology

[0002] Tissue slicer is a machine for cutting thin and uniform tissue slices. It can cut frozen biological tissues, paraffin tissue embedding blocks, diseased tissues or other substances. When testing slices, slices need to be as flat as possible, but currently The slices on the stage of the tissue slicer will curl upwards. The tissue slicers in various countries do not use a blower to make the slices automatically flattened, so it is inconvenient to make slices.

Abstract

A histotome objective table with an air duct comprises an objective table body. The internal upper portion of the objective table body is provided with an axial through penetrating hole penetrating through an air vent on the surface of the objective table body, and a cold air chamber is arranged in the lower portion of the objective table body. An air outlet end of the air vent is arranged on the right end face of the objective table body, and the right end face is provided with a tissue holder mounting hole. A steering fastening cover is provided with a downwardly-inclined first steering passage communicated with the air vent. A mounting rod of a paraffin bag embedded block holder can be mounted in the tissue holder mounting hole. A second steering passage and a third steering passage which are communicated are arranged in freezing holder body and an upper positioning holder of the paraffin bag embedded block holder, the second steering passage is connected with an air outlet end pipeline of the air vent, and the third steering passage inclines downwardly. The objective table body is assembled with a tissue holder according to needs. The upper portion of the objective table is provided with an invisible air vent connected with an electric fan, air is blown into tissue slices to be sliced, the slices are automatically spread, and slicing and spreading are fine in quality and high in efficiency.

Description

technical field [0001] The invention belongs to the field of biological tissue slicer components, in particular to a biological tissue slicer stage with an air channel. Background technique [0002] Tissue slicer is a machine for cutting thin and uniform tissue slices. It can cut frozen biological tissues, paraffin tissue embedding blocks, diseased tissues or other substances. When testing slices, slices need to be as flat as possible, but currently The slices on the stage of the advanced tissue slicer will curl upwards. The tissue slicers in various countries do not use a blower device to automatically flatten the slices, so it is inconvenient to make slices. Contents of the invention [0003] The object of the present invention is to provide a tissue slicer stage with an air channel, which is provided with an air hole (air channel), simple in structure, convenient and practical. [0004] The technical solutions adopted are: [0005] A tissue slicer stage with an air ch...
