Description

Technical Field

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

[0002] Paraffin slicer is an auxiliary machine widely used in medical and biological research, which is used to slice tissue after embedding it in wax. The slices made by paraffin slicer can be used to detect various clinical lesions to ensure that doctors can make more accurate judgments, or help researchers explore at the tissue and cell levels.

[0003] At present, when most paraffin slicers are used, it is necessary to clamp and fix the paraffin block first, and then slice the paraffin block with the blade on the knife holder. However, it is found in actual operation that the clamping end of most paraffin slicers often adopts a rotating clamping when clamping, and the clamping direction of the movable end of the clamping part is arc-shaped, while most wax blocks are square-shaped. When clamping, the arc-shaped clamping force may cause damage to the contact part between the wax block and the movable end, thereby causing a certain impact on the slice. Therefore, it is necessary to design a sample clamping device for a slicer to solve the above problem. Utility Model Content
