Description

Technical Field

[0001] This utility model relates to the field of fish egg microinjection, specifically a detachable and adjustable fish egg fixing device. Background Technology

[0002] With the rapid development of gene editing technology, fish egg microinjection has gradually become a routine procedure in fish gene editing. However, due to the differences in the size, hardness, and viscosity of eggs from different fish species, the arrangement and fixation of the eggs to be injected are extremely difficult. Furthermore, during the injection process, the eggs roll and collide, causing confusion between injected and uninjected eggs. Since microinjection needs to be completed rapidly within a short time, this poses a great challenge and obstacle for the experimental operators. To address this, this application proposes a detachable and adjustable fish egg fixation device. Utility Model Content

[0003] The purpose of this invention is to provide a detachable and adjustable fish egg fixing device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a detachable and adjustable fish egg fixing device, comprising a tray, wherein the tray is divided into several sub-chambers (3) by several partitions, and several egg support assemblies are fixedly installed on the tray in the vertical direction; several support grooves are respectively opened on both sides of the tray to engage with one end of each egg support assembly.

[0005] Preferably, the egg tray assembly comprises several linearly distributed egg tray blocks, and adjacent egg tray blocks are fixedly connected by a connecting plate.

[0006] Preferably, the two outermost egg tray blocks of the egg tray assembly are each fixedly connected to a handle at one end.

[0007] Preferably, each of the handles is adapted to the shape of the tray's support groove.

[0008] Preferably, the oocyte support assembly is divided into a first oocyte support assembly, a second oocyte support assembly, a third oocyte support assembly, and a fourth oocyte support assembly; the oocyte support blocks of the first oocyte support assembly, the second oocyte support assembly, the third oocyte support assembly, and the fourth oocyte support assembly are respectively provided with receiving grooves of different diameters.

[0009] Preferably, the outer wall of each of the oocyte receptacles is fitted to the inner wall of each ovarian cavity.

[0010] Compared with the prior art, the advantages of this utility model are as follows:

[0011] This invention selects the corresponding first, second, third, or fourth egg-holding assembly from the egg-holding components based on the size of the fish eggs to be injected. These assemblies are then fixedly placed on a tray. The first, second, third, and fourth egg-holding assemblies are marked with different colors or characters for easy identification under a microscope. The tray is then immersed below the surface of the egg-washing solution, and the eggs are pushed onto the tray. The tray is gently shaken to allow the eggs to enter the egg-holding assembly. The tray is then lifted from the solution for the next step of microinjection. By providing receiving grooves of different diameters in the egg-holding blocks of the first, second, third, or fourth egg-holding assemblies, it is easy to fix fish eggs of different sizes. Each egg-holding assembly is easily detached from the tray using handles on both sides. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example

[0017] Please see Figures 1-2 The figure shows a detachable and adjustable fish egg fixing device, including a tray 1. The tray 1 is divided into several sub-chambers 3 by several partitions 2. Several egg support components are fixedly installed on the tray 1 in the vertical direction. Several support grooves 8 are opened on both sides of the tray 1 to engage with one end of each egg support component.

[0018] In this embodiment, the egg support assembly includes several linearly distributed egg support blocks 401, and adjacent egg support blocks 401 are fixedly connected by a connecting plate 402. The two egg support blocks 401 located at the outermost edge of the egg support assembly are respectively fixedly connected to one end of a handle 403. Each handle 403 is adapted to the shape of the support groove 8 of the tray 1. The egg support assembly is divided into a first egg support assembly 4, a second egg support assembly 5, a third egg support assembly 6, and a fourth egg support assembly 7. The egg support blocks 401 of the first egg support assembly 4, the second egg support assembly 5, the third egg support assembly 6, and the fourth egg support assembly 7 are respectively provided with receiving grooves of different diameters. The outer wall of each egg support block 401 is respectively attached to the inner wall of each sub-chamber 3.

[0019] Furthermore, based on the size of the fish eggs to be injected, the corresponding first egg-holding container assembly 4, second egg-holding container assembly 5, third egg-holding container assembly 6, and fourth egg-holding container assembly 7 are selected and fixed on the tray 1. The first egg-holding container assembly 4, second egg-holding container assembly 5, third egg-holding container assembly 6, and fourth egg-holding container assembly 7 are marked with different colors for easy identification under a microscope. Then, the tray 1 is immersed below the surface of the egg-washing solution, and the eggs are pushed onto the tray 1. The tray 1 is gently shaken to allow the eggs to enter the corresponding first egg-holding container assembly 4, second egg-holding container assembly 5, third egg-holding container assembly 6, and fourth egg-holding container assembly 7. Then, the tray 1 is lifted out of the solution for the next step of microinjection. By setting the egg-holding container blocks 401 of the first egg-holding container assembly 4, second egg-holding container assembly 5, third egg-holding container assembly 6, and fourth egg-holding container assembly 7 with receiving grooves of different diameter sizes, it is easy to fix fish eggs of different sizes. Each first egg-holding container assembly 4, second egg-holding container assembly 5, third egg-holding container assembly 6, and fourth egg-holding container assembly 7 can be easily attached to and detached from the tray 1 via the handles 403 on both sides.

[0020] The working principle of this invention is as follows: Based on the size of the fish eggs to be injected, select the corresponding first egg-holding assembly 4, second egg-holding assembly 5, third egg-holding assembly 6, or fourth egg-holding assembly 7 from the egg-holding assembly components. These are then fixedly placed on the tray 1. The first egg-holding assembly 4, second egg-holding assembly 5, third egg-holding assembly 6, and fourth egg-holding assembly 7 are marked with different colors or characters for easy identification under a microscope. The tray 1 is then immersed below the surface of the egg-washing solution, and the eggs are pushed onto the tray 1. The tray 1 is gently shaken to allow the eggs to enter the corresponding egg-holding assembly. The tray 1 is then lifted from the solution for the next step of microinjection. The egg-holding blocks 401 of the first egg-holding assembly 4, second egg-holding assembly 5, third egg-holding assembly 6, or fourth egg-holding assembly 7 are provided with receiving grooves of different diameters, facilitating the fixing of fish eggs of different sizes. Each first egg-holding assembly 4, second egg-holding assembly 5, third egg-holding assembly 6, and fourth egg-holding assembly 7 can be easily attached to and detached from the tray 1 via handles 403 on both sides.
