1. Fitted with a sagittal positioning plate design，To minimize the levelness, inclination and alignment of the skull

2. The efficiency of cranial horizontal alignment is doubled, and the fixation process in animals is not repeated

3. More detailed five dimensional space positioning can meet the needs of other sites

4. The operation arm has been tested by the motor for 100,000 times, which makes it more durable

5. With 40X magnifier and horizontal calibrator, the skull flattening speed is faster and the brain area positioning accuracy is higher

6. Can be combined with inhalation anesthesia machine, animal mortality is low, the risk of surgery is small
