Embodiment 1

[0027] Comply with the above technical solutions, such as Figure 1 to Figure 4 As shown, the present embodiment provides a mouse optic nerve intrathecal injection needle, including a hook body 1, the inner bottom of the hook body 1 is provided with a positioning groove 2 recessed into the bottom of the hook, and the bottom of the positioning groove 2 is provided with a needle point 3;

[0028] The hook body 1 is provided with a fluid passage 4 , and the needle tip 3 is provided with a fluid outlet 5 , and the fluid outlet 5 communicates with the fluid outlet 4 .

[0029] As a preferred solution of this embodiment, the height of the needle point 3 is less than or equal to the depth of the positioning groove 2 ; preferably, the height of the needle point 3 is 0.4-0.8 times the depth of the positioning groove 2 . It is used to ensure that intrathecal injection can be performed after the mouse optic nerve 7 falls into the positioning groove 2, and to ensure that the needle tip 3...

Abstract

The invention provides a mouse optic nerve intrathecal injection needle, which comprises a hook body, a positioning groove recessed into the inner bottom of the hook body is formed in the inner bottomof the hook body, and a needle tip is arranged at the bottom of the positioning groove. A liquid passing channel is formed in the hook body, and a liquid outlet hole is formed in the needle tip and communicated with the liquid passing channel. The specific position of the optic nerve of the mouse can be well determined by a needle head in the form of the large hook body, the optic nerve of the mouse is restrained in the hook body firstly, and then accurate positioning and acupuncture are performed by the positioning groove, so that the success rate of intrathecal injection and acupuncture ofthe optic nerve of the mouse is greatly improved. Due to the smooth surface in the hook body, the optic nerve of the mouse can smoothly slide into the positioning groove in the bottom. The radian of the positioning groove can be attached to the outer wall of the optic nerve of the mouse to ensure that the optic nerve of the mouse does not slide out easily after entering.

Description

technical field [0001] The invention belongs to the field of medical devices and relates to an injection needle, in particular to a mouse optic nerve intrathecal injection needle. Background technique [0002] The diameter of the mouse optic nerve is small. In the prior art, during the intrathecal injection of the mouse optic nerve, it is difficult for the experimenter to accurately determine the exact position of the mouse optic nerve, and there is often a problem that the needle does not penetrate the mouse optic nerve sheath, resulting in The injection process failed and the success rate was not high, which made the experiment difficult and took a long time. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a mouse optic nerve intrathecal injection needle to solve the technical problem that the needle in the prior art is difficult to accurately penetrate the mouse optic nerve for intrathec...
