Central nerve fast precise cutting device and cutting method for experimental animal cadaver specimens

Abstract

The present invention relates to the field of neuroanatomy and biological experiment, and discloses a central nerve fast precise cutting device and a cutting method for experimental animal cadaver specimens. The cutting device comprises a chassis, an incisor fixation point, a tail vertebra fixation point and two ear rods. A strut perpendicular to the chassis is also fixed on the chassis; A cross bar parallel to the chassis is fixed on the support; Fixing a positioning corresponding scale parallel to the cross bar on the cross bar and the strut; A vertical bar perpendicular to the chassis is movably fixed to the cross bar; The vertical bar can move up and down, back and forth and left and right relative to the chassis; The bottom end of the vertical bar is fixed with a cutting part and a positioning pin; The anterior fontanel or spinal column of the cadaver specimen was positioned by moving the vertical bar with the positioning needle. The cutting component is used for transverse cutting of the cadaver specimen perpendicular to the spinal column of the cadaver specimen after positioning is completed, and the cutting component is used for transverse cutting of the cadaver specimen perpendicular to the spinal column. The central nervous system is located precisely, and the cutting operation is quick, simple and labor-saving.

Description

technical field [0001] The present invention relates to the field of neuroanatomy and biological experiments, in particular to a fast and precise cutting device and cutting method for the whole central nervous system of experimental animal (rats, mice, guinea pigs, rabbits, cats, etc.) cadaver specimens. Background technique [0002] Rats and mice are the most commonly used experimental animals, especially for research involving the nervous system. Almost all natural scientific knowledge of nerves comes from experimental animals such as rats and mice. [0003] For the study of the nervous system, many experiments are based on the morphological and electrophysiological studies of the brain and spinal cord. The brain and spinal cord are respectively located in the skull and spinal canal. Since the central nervous system is the most advanced product of natural development, the operation of the nervous system requires a very stable internal environment. Therefore, the cranial ca...

[0005] The second difficulty is the localization of the brain and spinal cord

Sometimes the desired structural parts are not obtained; sometimes, in order to ensure that the materials are not lost, the materials are often collected on a large scale, resulting in difficulties in secondary positioning; Denatured or metabolized, fast fixation is required; sometimes it is necessary to take a certain part of the central nervous system for physiological function research, and it is necessary to immerse the nerve tissue in an artificial physiological environment (culture solution) after rapid sampling
