The brain stereotaxic instrument is a device used to locate and fix the brain of experimental animals. During the experiment, the brain locator is first used to fix the animal's head so that it does not move relative to the animal. Then, the three-dimensional coordinate system specified by the marks on the outside of the animal's skull or other reference points is used to determine the location of certain neural nuclei under the cerebral cortex, such as the hippocampus, based on the brain localization map of the experimental animal, so as to perform targeted stimulation, destruction, drug injection, guided positioning and other operations on the neural nuclei under non-direct exposure. It can be used to establish animal models of Parkinson's disease, epilepsy, brain tumor models, learning and memory, brain neural stem cell transplantation, cerebral ischemia and other studies.
Meyue Bio's M5007 mouse and young rat brain stereotaxic instrument adopts a universal U-shaped base open structure, which is convenient for multi-angle operation; it can be applied to a variety of animal experiments (rats, mice, lizards, birds, cats and guinea pigs, etc.); the operating arm can rotate 180 degrees vertically and 360 degrees horizontally to provide researchers with flexible and precise positioning; it is also equipped with probes and electrode fixing clamps of various specifications, and can provide customized fixing clamps according to the different experimental requirements of users to meet various experimental requirements.

1. Suitable for brain positioning of mice and rats;
2. X, Y, Z coordinate movement range 0-80mm, reading accuracy 10um;
3. Accurate positioning in three-dimensional space and rotation adjustment of angles can be performed;
4. Vertical direction can rotate 180 degrees and lock any position at any time;
5. Vertical locking and positioning buttons are separated to ensure accurate operation at any angle, and precisely designed lateral rotation operation space;
6. Scale components treated with special processes eliminate fatigue caused by readings. The head of the animal adapter adopts a curved spring structure to tighten, which does not damage the animal's head structure and tissue and achieves the purpose of fixation;
7. The ear rod adopts a pressure plate and adds a spring at the same time; it pushes the left and right sides symmetrically to the middle to make the readings consistent;
8. Can be equipped with micro Precise positioning of injection pump, micro-camera, cranial drill, electrodes, etc.;
9. Optional animal adapters for rats, mice, cats, rabbits, geckos and guinea pigs, etc.;
10. Simple and exquisite appearance, convenient and flexible installation and adjustment methods;
11. Special mouse and young rat adapters are used, and the tip of the ear rod is appropriately tapered, which can not only firmly clamp the mouse head, but also avoid damage to the mouse skull; the height of the ear rods on both sides and the height of the incisor clamp can be freely adjusted, with an adjustment range of 20mm, and with scales, which is convenient for adjusting the skull level; for young rats, a zygomatic fixation sleeve is added to replace the tip of the ear rod, providing a non-invasive and stable fixation method for the head of the young rat; four tips of the ear rod are available.
12. To prevent misoperation, a one-button locking mechanism is added to the Y direction (to prevent misoperation in the middle of the experiment)
13. One-button zero position design of the rotating seat (to ensure the verticality of the cross arm)
