Abstract

The invention discloses a split-type low-temperature tissue divider, comprising: a pressing-type sampling and fixing device, which has a sleeve, a movable rod with one end arranged in the sleeve, and a pressing rod respectively connected to the sleeve and the movable rod; a tissue sampling device, It has a connecting rod that is detachably connected to the other end of the movable rod and has a central through hole, and a material-taking head that is connected to the connecting rod at one end and has a cutting edge at the other end; wherein, the sleeve, the movable rod and the material-taking head are respectively provided with There is a material containing chamber for storing low-temperature substances, so as to realize the low-temperature material collection of the sampling head through the low-temperature substances flowing through the material containing chamber; wherein, when the pressing rod is pressed, the movable rod is driven to move relative to the sleeve, so as to be compatible with the The connecting rod connects or separates. The divider of the present invention uses the sampling head for one-time use, effectively prevents the problem of cross-contamination caused by samples from different sources during the sampling process of the sampling head, can realize low-temperature environment sampling, ensures the quality of the obtained samples, and facilitates subsequent analysis of the samples.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a split-type low-temperature tissue divider. Background technique [0002] In the prior art, the collection of biological samples needs to ensure rapid segmentation and rapid freezing during the sample collection process, so as to ensure the quality of the isolated samples to the greatest extent. In order to meet the actual needs of rapid and standardized collection, the prior art discloses a medical tissue specimen divider (Chinese Patent No. is CN20887885.2), this splitter solves the problem of how to get materials quickly, but, because the sampling head of this splitter cannot be replaced, there is the problem of cross-contamination of samples from different sources. The quality of the obtained samples cannot be kept at an optimal state, which affects the subsequent analysis and processing of the samples. Contents of the invention [0003] The purpose of the present...
