Description
Technical Field
[0001] The utility model relates to the technical field of puncture devices, in particular to a puncture device for experimental animals. Background Art
[0002] In many studies involving experimental animals, it is often necessary to obtain tissues from the required parts for testing in stages. In the face of such experiments that require continuous observation of tissue changes, the current practice is to raise multiple animals at the same time, then treat some experimental animals at the stage where observation is required, and then obtain experimental tissues for observation. This practice requires the cultivation of many experimental animals, consumes a lot of manpower and material resources, and is inhumane to the experimental animals themselves. In addition, we can only assume that animals in the same batch have similar characteristics, and differences between individuals are inevitable. For some high-demand experiments, this staged observation method is prone to incorrect results. Therefore, in some experiments with rigorous designs or where experimental animals are scarce or difficult to cultivate, puncture technology is needed to obtain staged tissue specimens. The basic process of puncture is to puncture the required puncture site with a puncture device after the experimental animal is anesthetized. This is an imitation of human puncture, but due to the lack of subjective control awareness of experimental animals, this method is sometimes prone to cause stress in experimental animals and damage to operators. At the same time, the existing puncture device has a fixed length of puncture needle and cannot be adjusted according to the distance between the target position and the epidermis, which easily leads to the problem that the puncture needle is bent due to being too long or too short to puncture the tissue during the puncture process. Therefore, in order to solve the above problems and make the puncture process safer and more stable, we have invented such a puncture device for experimental animals. Utility Model Content
