Description

Technical Field

[0001] The utility model relates to the technical field of living body experiment auxiliary instruments, in particular to a gripping and fixing clamp for experimental mice. Background Art

[0002] Laboratory mice refer to small rodents used for scientific research and experiments. Common laboratory mice include mice and rats. They are usually used in research in the fields of medicine, biology, and psychology because they have a short reproductive cycle, are easy to reproduce, their genomes have been deeply understood, and their physiological and behavioral characteristics are similar to those of humans. Therefore, they have become important model animals in scientific research. In pathological research, most of the live experiments are conducted using mice. Mice are easy to obtain and have strong vitality. Using them in research can reduce the cost of research.

[0003] However, when current laboratories use experimental mice for related experiments, the mice often turn around and bite the hands of the experimenters because the mice's heads are not fixed properly during the grasping or experiment process. Taking "abdominal surgery after intraperitoneal injection of anesthesia" as an example, the traditional method is often to pinch the skin on the back of the mouse's neck with the left hand so that the mouse cannot turn around, and then complete the operation of intraperitoneal injection of anesthetics with the right hand. However, at this time, the operator's attention is often on the right hand holding the syringe, and the left hand muscles are prone to fatigue after a long operation time, resulting in poor fixation of the mouse's head, which leads to the experimenter being bitten by the mouse. In addition, even if there is no mistake during the injection, when the mouse's head and limbs are fixed on the operating table next, it is easy for the operator to be bitten by the mouse for similar reasons. On the other hand, the repeated grasping and fixing of mice in the experiment can easily cause harm to the experimental animals, affecting the experimental results and efficiency.

The experimental mouse grabbing and fixing clamp 100 can be used to fix the head and body of the mouse through the mouse head component 120 and the mouse body component 130 to prevent the mouse from moving around and biting due to being frightened, thereby reducing the risk of causing harm to the experimenter. At the same time, due to the effect of the reset part, there is no need to continuously apply force by hand, which is conducive to improving the convenience of operation. The mouse tail component 140 can store the mouse tail in the cylinder to ensure that the experimental operation will not be disturbed by the swinging of the mouse tail. In addition, the experimental mouse grabbing and fixing clamp 100 can be made into different models according to the size of the experimental mouse, and can be used to fix experimental mice of different sizes to improve the safety and efficiency of the experiment.

[0024] In one embodiment, see Figure 1 The mouse head assembly 120 includes two mouse head fixing tubes 121, each of which is connected to one end of the two clamp bodies 111, and each of which is semi-cylindrical. When the two mouse head fixing tubes 121 are closed, they are used to fix the mouse head.

[0025] The working principle and beneficial effects of the above technical solution are: the mouse head is fixed by clamping, which is convenient for operation.

[0026] In one embodiment, Figure 1 As shown, along the length direction of the mouse body component 130 , starting from one end of the clamp body 111 toward the outside, the diameter of the mouse head fixing tube 121 first remains unchanged and then increases.
