Device for cutting tissue of organisms

Abstract

The invention discloses a device for excising tissue of a creature, which comprises an external pipe and a horizontal excising component; one end of the horizontal pipe is a column-shaped vertical incising component; the horizontal excising component comprises a whirling arm and a horizontal incising component which are connected with each other to form an angle of 90 degrees; the horizontal excising component is arranged in the cavity of the external pipe and in clearance fit with the cavity; the whirling arm and the vertical incising component are coaxial; and the horizontal incising component and the free end of the vertical incising component are coplanar. The device overcomes the disadvantage that the tissue can not be excised quantitatively in the prior art, achieves quantificational excision of the tissue, and has the beneficial effects of high repeatability, minor tissue damage, simple structure, convenience operation and low cost.

Description

technical field [0001] The invention relates to a biological tissue resection device. Background technique [0002] In the field of life sciences, experiments are the basis for the development of disciplines, especially animal experiments, which are an important part of life sciences. Modern science has increasingly high requirements for animal experiments, which must be scientific. Scientificity requires the stability of animal experiments, that is, the reliability and repeatability of animal experiment results. In the current injury model of the central nervous system, it is necessary to quantitatively remove part of the tissue from the solid tissue, resulting in localized damage or cavity. The commonly used methods are generally sucking tissue with aspirator, digging out the tissue with a spoon, etc., but these methods are all done by human touch, their repeatability is poor, and they cannot be quantified at the same time. These shortcomings have seriously affected The...

Current CNS injury models require quantitative resection of tissue from solid tissue, resulting in localized lesions or cavities

The commonly used methods are generally sucking tissue with aspirator, digging out the tissue with a spoon, etc., but these methods are all done by human touch, their repeatability is poor, and they cannot be quantified at the same time. These shortcomings have seriously affected The accuracy and reproducibility of subsequent experiments hinders the development and progress of science
