Pipette egg transfer needle adapter

Abstract

The invention discloses a pipette egg transfer needle adapter. The pipette egg transfer needle adapter comprises a spearhead interface, a fastening nut and a sealing rubber ring group; the spearhead interface, the fastening nut and the sealing rubber ring group are all of revolving body structures, through holes are formed in the spearhead interface, the fastening nut and the sealing rubber ring group in the axial direction, the fastening nut sleeves the front of the spearhead interface, and the fastening nut and the spearhead interface are connected by threads. The sealing rubber ring group is installed in an inner cavity of the fastening nut and is pressed between the spearhead interface and the fastening nut. The pipette egg transfer needle adapter has the beneficial effects that the adapter can form a simple and convenient pipette egg transfer needle system with various kinds of egg transfer needles, compared with an original method, the processing and transfer of various embryos such as follicle removal, oocyte, fertilized eggs, blastaea can be more easily, quickly, and accurately realized, granular cells are separated, the activity of the embryos during operation is ensured,and efficiency and reliability of embryo processing and transfer operation are improved.

Description

technical field [0001] The invention relates to the technical field of biomedicine, in particular to an adapter for a pipette egg transfer needle. Background technique [0002] At present, in the treatment of mammalian embryos or IVF embryos in scientific research activities, the classic method of follicle treatment and removal of various eggs, fertilized eggs or embryos of various stages is the mouth pipette method, which is time-consuming and laborious. Moreover, a lot of practice is required to master the relevant technical essentials. At present, there is still an egg stripper method for treatment. This method requires the purchase of a special egg stripper and supporting consumables. It also requires a certain amount of practice, and the accuracy is difficult to control. In such a laboratory, whether it is scientific research or clinical practice, there are a large number of common pipettes.

Problems solved by technology

[0002] At present, in the treatment of mammalian embryos or IVF embryos in scientific research activities, the classic method of follicle treatment and removal of various eggs, fertilized eggs or embryos of various stages is the mouth pipette method, which is time-consuming and laborious. Moreover, a lot of practice is required to master the relevant technical essentials. At present, there is still the method of egg stripper. This method requires the purchase of special egg strippers and supporting consumables. It also requires a certain amount of practice, and the accuracy is difficult to control.

In such a laboratory, whether it is scientific research or clinical practice, there are a large number of common pipettes. The use of these pipettes with different ranges is very convenient and familiar for embryo operators, and the accuracy of key operations is also guaranteed. There are also a large number of egg transfer needles that were originally used for oral suction pipettes or egg strippers, but the current situation is that conventional egg transfer needles cannot be used directly on ordinary pipettes. If this problem is solved, it will greatly facilitate the embryo handling operation. To improve the precision and accuracy of the operation and ensure the success rate of the experiment, how to solve this problem puts forward requirements for us

[0003] At present, in scientific research and clinical work that needs to process and remove mammalian embryos, the mouth pipette method is routinely used to process embryos, that is, one hand controls the microscope and the other controls the operating needle. The operating needle is connected to one end of the pressure tube, and the other end is directly connected to the tube. In the mouth of the operator, the change of pressure in the mouth is used to drive the change of pressure in the operating needle to achieve the purpose of removing and releasing eggs and separating granulosa cells. This method is time-consuming and laborious, and requires repeated training. The accuracy cannot be guaranteed. The key Unfortunately, the safety of embryos and operators cannot be guaranteed

In addition, in the current embryo treatment of reproductive medicine, a special egg stripper has appeared, that is, a special equipment is connected to a specially equipped egg transfer needle, the embryo is sucked into the operation needle tube, and the egg is repeatedly blown to separate the negative egg from the surrounding area. For the purpose of granulosa cells, this method requires even special equipment and consumables, and requires a lot of repeated practice, and the operation accuracy is relatively rough, it is difficult to accurately control, and the activity of embryos cannot be guaranteed.
