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

Embodiment 1

[0030] This embodiment provides a tissue block cutting device, such as figure 1 As shown, it includes a handle 1, a fixed cylinder 2, a rotating cylinder 3, a fixed disk 12, a positioning needle, a blade 5 and a blade 6, the fixed cylinder 2 is fixedly connected with the handle 1, and the positioning needle is vertically fixed to the handle 1; the rotating cylinder 3 One end is clamped with the fixed cylinder 2, and the other end is clamped with the fixed plate 12; the fixed plate 12 is fixed with the positioning pin. The blade 5 is sleeved on the outside of the positioning pin and can move up and down along the inside of the rotating cylinder 3 , and the blade 6 is fixed below the blade 5 .

[0031] Specifically, the fixed cylinder 2 is a cylinder, one end of which is fixedly connected with the handle 1 and the central axes of the two coincide. The handle 1 is used for the operator to hold, and its shape can be set according to the actual situation, for example, it can be ci...

Abstract

The invention discloses a tissue block cutting device. According to the technical scheme, the tissue block cutting device comprises a handle and a positioning needle fixed to the handle. A fixed cylinder and a rotating cylinder are sequentially arranged on one side of the handle, and the fixed cylinder and the rotating cylinder can rotate relatively; the rotating cylinder can rotate relative to afixed disc fixed on the positioning needle; and the interior of the rotating cylinder is in threaded connection with a plurality of blades, and a blade penetrating through the fixed disc is fixed to the axial side face of each blade. According to the tissue block cutting device, the effect of smoothly cutting harder and tougher small tissue blocks can be achieved, and the length or area of the cuttissue blocks can be conveniently calculated.

Description

technical field [0001] The invention relates to the field of biological scientific research experiment tools, in particular to a tissue block cutting device. Background technique [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 cannot calculate the length or area. 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 a tough tissue block requires aseptic operation, it is more difficult to cut with tweezers or pliers with the other hand. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a tissue block cutting...
