Description

Technical Field

[0001] The utility model relates to the technical field of sample slicing, in particular to a paraffin sample slicing device. Background Art

[0002] Paraffin sectioning is the most widely used method in conventional slide making technology. Paraffin sectioning is not only used to observe the morphological structure of normal cell tissues, but is also the main method used by disciplines such as pathology and forensic medicine to study, observe and judge the morphological changes of cell tissues. It has also been widely used in research in many other disciplines. Paraffin sectioning usually requires steps such as sampling and wax dipping to obtain paraffin blocks containing tissue specimens, which are then removed.

[0003] The publication number in the existing public technology is: CN215433925U. A paraffin section device includes a base, a fixed sleeve, a pushing block, a fixed ear, a rotating rod, a connecting frame, a handle, a blade, a liquid storage tank, a screw, a side plate, a sliding seat, a supporting column, a crank, a liquid outlet pipe, a sliding block, a fixed layer, a connecting rod, a limit plate and a supporting spring. The base is provided with a liquid storage tank, and a screw is arranged inside the liquid storage tank through a sealed bearing. The screw passes through the liquid storage tank and extends to one side of the base. A crank is arranged on one side of the base, and the crank is connected to the screw. A slidable sliding block is arranged on the screw, and the sliding seat is placed on the sliding block through a connecting rod. The utility model overcomes the shortcomings of the prior art, can fix and clamp the paraffin block, and appropriately adjust its temperature through a water bath to change the hardness of the paraffin block, and can manually cut it into multiple thin slices for sample selection.

[0004] However, the above patent still has certain disadvantages when in use: the distance between the blades of the device is fixed, so the paraffin block can only be cut into slices of fixed thickness, which has certain limitations. In addition, waste chips will inevitably be generated during the slicing process, and these fragments will be concentrated in the fixed layer. If they are not cleaned in time, cross-contamination between different samples will occur. After slicing, sample debris will also remain on the surface of the blade. Therefore, it is also necessary to clean the surface of the blade after slicing to prevent cross-contamination and affect the quality of slicing.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
