Information
High-precision stepping motor
The high-precision stepper motor stably outputs a minimum step angle of 0.04, which is a minimum displacement of 0.33μm, ensuring the accuracy requirement of 1μm. A high-precision projector is used to detect the accuracy of the motor to meet
the needs of higher-precision experiments.

Frame calibration
Quickly calibrate three-axis coordinate values, users can calibrate by themselves.
Constant Speed
The AP or ML axis has 5 adjustable speeds, the DV axis has 9 adjustable speeds, and the lowest speed in the DV direction can reach 1μm/s.
Reduce jitter at a uniform speed to ensure precise positioning. Reduce mechanical damage. Prevent massive bleeding from affecting surgery.
Built-in Atlas
The software integrates the rat and mouse brain atlas, which can display the movement trajectory and position of the probe in real time and keep track of the experimental progress.
No Leveling Required
By determining four points to determine the skull tilt angle, accurate positioning can be achieved without leveling through angle calculation.
(Bregma, Lambda, 2mm left and right of the sagittal suture) At the same time, the brain atlas can be scaled according to the actual skull
size, making the positioning more accurate.
Automated Injection
The software directly controls the nanoliter syringe pump for single-point, multi-point and tilted injection. Tilted injection also does notrequire manual calculation of the three-axis displacement after tilting. The injection precision is high, the injection volume is 0.6-5000nL, and the injection rate is 0.02-200nL/s. The needle withdrawal speed can be customized, with a minimum of 1μm/s. Slowly withdrawing the needle can prevent drugs or viruses from spilling into the needle tract. Multi-point injection procedure can achieve up to 10 injection sites. Needle retention time setting can realize automated needle retention and extraction. Real-time display of injection progress.
Tilted Trajectory: Manipulator Tilted Function
Traditional positioning methods require manual calculation of the three-axis displacement distance after tilting when performing experiments such as tilt injection or implantation, which is time-consuming and labor-intensive. The Automated Stereotaxic Instrument includes a tilted trajectory function, eliminating the need to manually calculate the displacement distance after tilting. It can be used for experiments such as tilted craniotomy, tilted injection and tilted implantation.
Optional Dual Manipulators
It can realize experiments such as injection and implantation of bilateral brain areas of the same animal, which is more efficient.
Automated Craniotomy: Skull Windows Function
You can choose a round or square window, which is suitable for brain imaging scenarios, such as miniscope calcium imaging experiments, two-photon imaging or other brain imaging experiments before craniotomy.
Tissue Removal
Equipped with a tissue removal kit, it is used to remove tissue before implanting the GRIN Lens. It is suitable for miniscope calcium imaging experiments.

How It Works
Stereotaxic surgery utilizes a three-dimensional coordinate system referenced to anatomical landmarks on the skull to achieve precise targeting of internal brain structures. The instrument positions the animal's head in a standardized orientation using ear bars and a nose clamp, establishing consistent anteroposterior (AP), mediolateral (ML), and dorsoventral (DV) coordinate planes relative to bregma and lambda cranial sutures.
High-precision stepper motors control manipulator movement along each axis with anti-backlash mechanisms to ensure accurate positioning without mechanical drift. The integrated brain atlas provides anatomical coordinates for target structures, while the automated injection system delivers precise volumes through glass micropipettes or metal cannulae. Programmable injection protocols control infusion rates and volumes, with automated needle withdrawal at specified speeds to minimize tissue damage and backflow.
Self-calibration functions establish coordinate zero points and compensate for minor variations in animal positioning, while tilted trajectory capabilities enable approach angles that avoid critical structures or optimize injection site access.

Practical Tips
Perform self-calibration before each experimental session and verify positioning accuracy using known reference points.
Why: Temperature variations and mechanical settling can introduce small coordinate shifts that affect targeting precision.
Flush injection pathways with sterile saline between different solutions and perform thorough cleaning after viscous or particulate solutions.
Why: Residual solutions can cause blockages or cross-contamination that affects injection accuracy and experimental validity.
Use the tilted trajectory function to approach targets at optimal angles that avoid surface vessels and minimize tissue displacement.
Why: Angled approaches can reduce bleeding and tissue damage while maintaining accurate targeting of deep brain structures.
Program injection protocols with gradual rate increases and pause periods to minimize pressure artifacts and tissue damage.
Why: Rapid injection can cause tissue displacement and backflow that reduces effective dose delivery and creates pressure-induced artifacts.
If positioning accuracy decreases, check for mechanical obstructions and verify that anti-backlash functions are properly engaged.
Why: Mechanical play in drive systems can accumulate positioning errors that compound during multi-site procedures.
Record actual injection volumes and rates achieved during procedures to verify protocol execution and document any deviations.
Why: Automated systems can experience flow resistance or blockages that affect intended doses without obvious operator feedback.
Ensure proper anesthesia depth monitoring during automated procedures and maintain backup manual override capability.
Why: Automated procedures can continue execution during anesthesia complications, requiring operator intervention to maintain animal safety.
