However, securing a microneedle, pierced with a tiny insect, to a specimen box or other support is difficult due to the small size of the microneedle and the limited operating space. Therefore, the inventors have proposed a micro-insect needle securing device. Utility Model Content

[0029] In order to make the purpose, technical solutions and advantages of this application clearer, the application is further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain this application and are not used to limit this application.

[0030] See also Figures 1-4In this embodiment, a micro insect needle fixing device includes a base 10 and a connector 20; wherein, the periphery 11 of the base 10 protrudes along the thickness direction and encloses a groove 12; the connector 20 is arranged at both ends of the groove 12, and the connector 20 has a through hole 21 that penetrates the base 10 along the thickness direction; there is a gap between the connector 20 and the side wall of the groove 12, and the end of the through hole 21 gradually expands from the inside to the outside, one of the through holes 21 is connected to the microneedle 40 with limited rotation, and the other through hole 21 is connected to the fixing needle 30 with limited rotation.

[0031] By adopting the technical solution of this embodiment, a through hole 21 is provided on the connecting part 20, and the connecting part 20 is provided in the groove 12 and there is a gap between it and the side wall of the groove 12. The port of the through hole 21 is designed as a gradually expanding structure, which makes the position of the through hole 21 easier to observe and confirm, thereby improving the convenience of installing the fixing needle 30 and the microneedle 40 into the through hole 21. The microneedle 40 pierced with tiny insects is fixed by the fixing needle 30, thereby improving the convenience of microneedle fixation.

[0032] It should be noted that the base 10 is constructed as an elliptical slat as a whole. The base 10 has a certain thickness, and the base 10 has an upper surface and a lower surface parallel to each other. The periphery of the base 10 protrudes and extends to the upper and lower sides along the thickness direction of the base 10, so that a groove 12 is enclosed on the upper and lower surfaces of the base 10, and the groove 12 remains symmetrically arranged on the upper and lower surfaces of the base 10.

[0033] In addition, the connecting member 20 is constructed as a whole in a cylindrical shape. The connecting member 20 and the base 10 are an integrally molded structure and are made of polymer materials with good elasticity, aging resistance, good stability, and strong wrapping properties. A connecting member 20 is provided at both ends of each groove 12, and the two ends of the groove 12 are constructed into an arc arranged coaxially with the connecting member 20. The connecting member 20 remains symmetrically arranged at both ends of the groove 12. At the same time, the connecting member 20 remains symmetrically arranged on the upper and lower surfaces of the base 10.

[0034] In addition, the axis of the connector 20 is arranged perpendicular to the upper and lower surfaces of the base 10, the through hole 21 is provided at the axis of the connector 20, and the port of the connector 20 is configured to be a trumpet shape that gradually expands from the inside to the outside.

[0035] Please note that Figure 2 and Figure 4 The end of the microneedle 40 away from the pierced insect (i.e., the lower end) extends to the bottom of the through hole 21 and bends. The bending form can be, but is not limited to, a 90-degree bend or a circular bend. The microneedle 40 is rotated through the bent portion, and the insect pierced by the upper end of the microneedle 40 is driven to rotate synchronously to adjust the insect's posture.

[0036] It should be understood that since the fixing needle 30 and the microneedle 40 are thin and have a small overall size, and at the same time, the two through holes 21 form a restricted rotational connection with the fixing needle 30 and the microneedle 40 respectively, the aperture of the through hole 21 is small, which makes it difficult to identify. In this embodiment, the connector 20 is arranged inside the groove 12, and there is a gap between the connector 20 and the side wall of the groove 12, so that the position of the connector 20 on the base 10 is easier to identify. At the same time, the through hole 21 is arranged at the axis of the connector 20, and the port of the through hole 21 is arranged to be a trumpet shape that gradually expands from the inside to the outside, that is, the diameter of the port of the through hole 21 on the end face of the connector 20 is increased, so that the position of the through hole 21 is easier to identify, and thus the operation of inserting the fixing needle 30 and the microneedle 40 into the through hole 21 can be completed more quickly.

[0037] It should also be understood that in this embodiment, the base 10 serves as a transition structure to connect the fixing needle 30 and the microneedle 40 into one body. The needle tip of the microneedle 40 faces upward for piercing micro-insects, and the needle tip of the fixing needle 30 faces downward for being plugged and fixed on a specimen box or other carrier. This makes the fixing operation of the microneedle 40 easier, and both the fixing needle 30 and the microneedle 40 can rotate inside the through hole 21 to facilitate adjustment of the sample orientation.

[0038] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
