1. The operating arm has a movement range of 80mm vertically, horizontally, and depth-wise.
2. It can rotate 180° vertically and be locked at any position within this range, with a resolution of 2°; it can rotate 360° horizontally and be locked at any position within this range, with a resolution of 5°.
3. It has a positioner movement control function, including 4 control methods.
4. It has a positioner movement speed adjustment function.
5. It has a brain atlas calibration function.
6. It is equipped with an automatic craniotomy procedure, multi - site procedure settings, a tissue removal procedure, and a Z - axis retraction function.

The center has three brain stereotactic instruments. They use a three - dimensional coordinate system based on skull - surface landmarks or other reference points. This helps determine the position of certain subcortical neural structures. These instruments allow for targeted stimulation, lesioning, drug administration, and evoked potential studies without direct visualization.

Animal brain stereotactic instruments are crucial in neuroanatomy and neurosurgery. They enable precise injections, stimulations, and lesioning in the nervous system. These instruments can be used to establish intracranial tumor models and study learning and memory.
