Multifunctional animal tissue sampling cutter

Abstract

The invention discloses a multifunctional animal tissue sampling cutter which comprises a blade and a sample pressing drum integrally connected with the blade, wherein a cutting edge of the blade is composed of a sharp edge on a front section and a sawtooth edge at a rear end, and a sampling hole is formed on a drum wall of the sample pressing drum. The blade of the sampling cutter provided by the invention is composed of the sharp edge on the front section and the sawtooth edge at the rear end which are used together for sampling the high-toughness animal tissue, so that the animal tissue can be quickly cut and taken, the time and labor are saved and the operation is convenient and quick. Meanwhile, the sample pressing drum is used for sampling by the multifunctional animal tissue sampling cutter, so that the time is saved, the size of the sample can be conveniently controlled, and the sample pressing drum also can be used as a handle of the sampling cutter. The multifunctional animal tissue sampling cutter not only can bring convenience to the operator, but also can solve the problems of single function and long sampling time of the present sampling cutter, and can be widely popularized in the areas of schools, enterprises, research institutions, and the like, and has obvious benefits.

Description

technical field [0001] The invention relates to a multifunctional animal tissue sampling knife, which belongs to the technical field of test equipment. Background technique [0002] At present, in the process of collecting animal tissue samples, there are still some problems with the traditional animal tissue sampling knife. Sample collection is difficult, resulting in a greatly reduced sampling speed; the second is when the sample demand is large (that is, multiple samples need to be collected for each tissue) and needs to be stored in a container with a fixed size (generally required to be stored in RNA cryopreservation tubes). Middle), the previous sampling tools were unable to quickly cut tissue samples of the same size, and the organs were exposed to the air for too long, which caused errors in later experiments such as DNA and RNA extraction. Therefore, in order to improve sampling efficiency, reduce sampling time, save energy and avoid affecting the accuracy of subse...

[0002] At present, in the process of collecting animal tissue samples, there are still some problems with the traditional animal tissue sampling knife. Sample collection is difficult, resulting in a greatly reduced sampling speed; the second is when the sample demand is large (that is, multiple samples need to be collected for each tissue) and needs to be stored in a container with a fixed size (generally required to be stored in RNA cryopreservation tubes). middle), the previous sampling tools could not quickly cut out the tissue samples of the same size, so the organs were exposed to the air for too long, which caused errors in later experiments such as DNA and RNA extraction

Therefore, in order to improve sampling efficiency, reduce sampling time, save energy and avoid affecting the accuracy of subsequent experiments due to improper operation in the sampling process, it is necessary to study and design a multifunctional animal tissue sampling knife.
