Freezing carrier rod and support combination

Abstract

The invention relates to the technical field of medical instruments, in particular to a freezing carrier rod and support combination. The device comprises a substrate and a carrier rod; the carrier rod comprises a handle and a slide, and the front end and the rear end of the handle are respectively provided with a supporting block; one or more placing grooves distributed in parallel are formed inthe substrate, two limiting notches matched with the supporting blocks are formed in the placing grooves, and supporting feet for adjusting the height of the substrate are arranged at the bottom of the substrate; and when the carrier rod is placed on the placing grooves, the outer end of the slide is exposed out of the substrate to be distributed. According to the freezing carrier rod and supportcombination, the placing grooves and the limiting notches in the substrate are used and are matched with the supporting blocks on the carrier rod to fix the carrier rod so as to provide a stable operating environment for the carrier rod; meanwhile, a plurality of placing grooves which are distributed in parallel are arranged, so that a plurality of samples can be operated at one time, the operation time is reduced, and the freezing storage efficiency is improved; the height of the substrate is finely adjusted through supporting legs, so that the clearest visual field can be quickly found undera microscope, and the operation efficiency is further improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a combination of frozen rod holders. Background technique [0002] As the number of infertility patients increases year by year, more and more people receive assisted reproductive assistance, and embryo cryopreservation technology has become the main solution for embryo preservation. At present, when gametes or embryos are cryopreserved, it is necessary to The transfer operation of gametes or embryos is carried out under a microscope, and the gametes or embryos in the petri dish are transferred to the freezing rod for cryopreservation. [0003] During this process, two methods are often used to fix the loading rods. One is the hand-held method. This method will cause shaking due to the acidity of holding the frozen loading rods for a long time, and the stability is poor. This may increase the embryo storage time, which is not conducive to the development of embryos. cryo...

Problems solved by technology

[0003] During this process, two methods are often used to fix the loading rod. One is the hand-held method. This method will cause shaking due to the acidity of holding the frozen loading rod for a long time, and the stability is poor. This may increase the embryo storage time, which is not conducive to embryo cryopreservation, the latter is the shelving method, which is to place the frozen load rod on some kind of utensil. Although this method has good stability, the utensils currently used have special requirements for the shape of the microscope, so the scope of use Narrow, and it is difficult to accurately identify the carrier rod used for the corresponding embryo under the microscope
