Biological frozen tissue cutting device

Abstract

The invention discloses a biological frozen tissue cutting device which is used for achieving the fast cutting on frozen biological tissues. The biological frozen tissue cutting device comprises a base, a support, a stand column, a pressing plate, cutting tools and a splash guard cover, wherein the upper portion of the base is provided with the support, one side of the support is provided with the stand column moving vertically relative to the support, and a driving assembly used for driving the stand column to ascend and descend is arranged between the stand column and the support; the pressing plate is fixed onto the bottom of the stand column, the bottom of the pressing plate is provided with a plurality of installing frames, the installing frames are located on the same circumference and evenly distributed on the circumference, at least two of the installing frames are provided with the cutting tools, and the cutting tools are provided with blades used for cutting biological tissues; the splash guard cover is arranged on the position, under the pressing plate, of the base, and biological frozen tissues to be cut are placed in the splash guard cover. According to the biological frozen tissue cutting device, a motor drives the pressing plate to descend to drive the blades to descend, the blades extrude the frozen tissues to achieve the cutting of the frozen tissues, and the problem that direct manual pressing of the blades wastes time and strength is solved.

Description

technical field [0001] The invention relates to the technical field of biological experiment equipment, in particular to a device for cutting frozen tissues. Background technique [0002] During the preservation of biological tissue materials, it is necessary to use liquid nitrogen for cryopreservation to avoid degradation of proteins and the like. Frozen biological tissue materials are generally large in size or frozen together. When performing experiments, only a small piece is often used, so the biological tissue material needs to be thawed and then cut. However, in many cases, it is too late to wait for the biological materials to thaw, and biological experiments need to be carried out in time. Therefore, there is an urgent need for a cutting device for conveniently cutting biological tissue materials. Chinese patent 201420744159X discloses a device for cutting frozen tissue blocks. The cutting knife is provided with four blades arranged in a "ten" shape, and the biolo...

AI Technical Summary

Problems solved by technology

In this way, people need to exert pressure on the cutting knife, which is time-consuming and labor-intensive, and the size of the divided biological tissue blocks is fixed, and large biological tissue will cause waste of resources when conducting experiments.
