A scaffold for single-cell tubing in preimplantation genetic diagnosis

Abstract

The invention relates to a bracket used for implanting a pre-implantation genetic diagnosis single-cell tube. The bracket comprises a bracket body with a framework structure and regulating assemblies, wherein two opposite side surfaces of the bracket body are respectively provided with one group of regulating assemblies; each of the regulating assemblies comprises a longitudinal regulating guide rail, a regulating rod, a transverse regulating assembly, a clamping arm and a locking piece; the longitudinal regulating guide rails are fixed on the side surfaces of the bracket body, the regulating rods are sleeved on the longitudinal regulating guide rails and fixed by the locking pieces; each transverse regulating assembly comprises a connecting ring I and a connecting ring II; the connecting rings I are sleeved on the regulating rods and fixed by the locking pieces; the clamping arms pass through the connecting rings II and are fixed by the locking pieces; one end of each of the clamping arms of the two groups of the regulating assemblies is respectively provided with a PCR (polymerase chain reaction) tube fixing clamp and a micromanipulation arm fixing clamp. The bracket disclosed by the invention can be used for avoiding a phenomenon that segmentation spheres are lost as operation staff cannot precisely grab segmentation spheres, and has the advantages of being flexible to move, simple to operate, low in manufacturing cost, capable of being sterilized and maintained, large in operation range, and the like.

Description

technical field [0001] The invention relates to a scaffold used for preimplantation genetic diagnosis single cell tube loading. Background technique [0002] With the development of Assisted Reproductive Technology (Assisted Reproductive Technology, ART), it has developed to the third generation of ART technology, that is, Preimplantation Genetic Diagnosis (PGD). This technology was successful in 1990. It is mainly aimed at people with family genetic disease history and advanced maternal age. In the early stage of embryonic development, a blastomere is removed by embryo biopsy. After molecular biological testing, normal embryos will be transferred into the woman's uterus. The abnormal embryos are discarded, thereby improving the overall birth quality of the population and improving the quality of the population. Therefore, the demand of the majority of patients for this technology is also increasing. [0003] At present, there is no dedicated PCR tube holder for loading bl...

AI Technical Summary

Problems solved by technology

[0005] The main technical problem to be solved by the present invention is to provide a simple structure, large operating range, low manufacturing cost, flexible movement, and simple operation; it can avoid the failure of the blastomere due to the inability of the operator to accurately grasp the blastomere. Lost scaffolds for preimplantation genetic diagnosis single-cell tubing to solve the above-mentioned problems in the prior art
