Rat tail cutter

Abstract

The invention discloses a rat tail cutter which comprises a box body, a rat tail clip and a cutting blade. Both ends of the box body are provided with openings, and the outer walls of the tops of thetwo ends of the box body are provided with an inlet plate insertion groove and an outlet plate insertion groove respectively. Equidistantly-distributed baffle insertion grooves are formed in the outerwall of the top of the box body, and the baffle insertion grooves are located between the inlet plate insertion groove and the outlet plate insertion groove. The vertical sections of the inlet plateinsertion groove, the outlet plate insertion groove and the baffle insertion grooves each are of a C-shaped structure. An inlet plate is inserted in the inlet plate insertion groove and includes a porous inlet plate and a clamping piece plate. A rat head clamping plate is inserted in the outlet plate insertion groove, and baffles are inserted in the baffle insertion grooves. According to the rat tail cutter, the position of a support can be adjusted according to the length or weight of the rat and the part of the rat to be exposed, an adjustment can be made according to sizes and lengths of different rats, the rat tails and rat heads can be fixed, to facilitate the taking of the rat tail and the marking on the rat ear, the time is saved, and a sample can be protected from pollution.

Description

technical field [0001] The invention relates to the technical field of rat tail truncation aids, in particular to a rat tail truncation device. Background technique [0002] Rats are the most commonly used animal models for biomedical experiments. Partial truncation of the rat tail is a common method for scientific research activities without damaging the animal body. For example, it is often necessary to truncate its tail by 3-5mm for genotype identification during experiments. Since mice are highly mobile and have a certain aggressiveness, it is usually necessary to fix the tail and the tail when taking a sample of the tail of the mouse, and cut off the part. Improper fixation or incomplete clipping and unclear marking can easily lead to injury to experimental personnel or experimental mice. At present, there is no tool or device to solve this problem. It is easy to cause animal panic, accidental bite and accidental injury to scientific research personnel, as well as diff...

Problems solved by technology

Improper fixation, incomplete cutting, and unclear marking can easily cause injury to experimenters or experimental mice

At present, there is no tool or device to solve this problem. Just relying on scientific researchers to grasp and fix them by hand can easily cause animal panic, accidentally bite and injure scientific researchers, as well as difficult to mark, inconsistent quantification, and sample contamination, which greatly increases scientific research. Personnel time and cycle costs
