Problems solved by technology

[0002] In biological scientific research experiments, it is often necessary to use small plant or animal tissue blocks. During the cutting process of tissue blocks, it often occurs that the tissue blocks are too hard or too tough, such as bone tissue and scar tissue, causing ordinary scissors to Or the operating knife cannot cut out a regular shape, and finally the length or area cannot be calculated
Or because the tissue block is too small, it is not easy to fix the tissue with one hand and cut it with the other hand, or when encountering a tough tissue block that requires aseptic operation, it is more difficult to cut with tweezers or pliers with the other hand

Abstract

The invention discloses a tissue block cutting device, the technical scheme of which is: comprising a handle and a positioning needle fixed to the handle; a fixed cylinder and a rotating cylinder are arranged in sequence on one side of the handle, and the fixed cylinder and the rotating cylinder can rotate relatively. the rotating cylinder and the fixed plate fixed on the positioning needle can rotate relatively; the interior of the rotating cylinder is screwed with a plurality of blades, and the axial side of each blade is fixed with a blade penetrating the fixed disk. The invention can also achieve the effect of smooth cutting for hard and tough small tissue blocks, and the cut tissue blocks are convenient to calculate the length or area.

Description

technical field [0001] The invention relates to the field of biological scientific research experimental tools, in particular to a tissue block cutting device. Background technique [0002] In biological research experiments, it is often necessary to use smaller plant or animal tissue blocks. In the process of cutting tissue blocks, it often occurs that the tissue blocks are too hard or too tough, such as bone tissue and scar tissue, resulting in ordinary scissors. Or the operating knife cannot cut out a regular shape, and finally the length or area cannot be calculated. Or because the tissue block is too small, it is not easy to fix the tissue with one hand and cut it with one hand, or when a tough tissue block requires aseptic operation, it is more difficult to operate with a pair of tweezers or forceps and the other hand to cut. SUMMARY OF THE INVENTION [0003] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a tissue blo...
