I. Usage Overview

• Used in conjunction with the stereotaxic instrument, this device supports localization, injection, recording, imaging and other related experiments.
• It fixes the animal’s head to enable further experiments on the legs, abdomen, back and other body parts.
• The manipulator arm adopts a coordinated design of lead screws and rolling mechanisms, ensuring long-term stability and precision of the coordinate axes.Meanwhile, it reduces the number of connecting joints, greatly eliminating errors caused by multi-joint connections and enhancing overall stability.

II. Component Description

Stereotaxic Instrument for Mice

• Mouse brain stereotaxic base
• Gas anesthesia inlet and rodent breathing outlet
• Head fixation device (secures the head via incisor clamps, nasal bridge support and ear canal inserts)
• Mouse body platform

3D Translation Stage for Ultrasound Probe

• Probe holder (compatible with 14–22 MHz L12 high-frequency small animal ultrasound probes)
• X-axis: adjusts longitudinal scanning of the mouse (motorized-manual integrated, precision: 10 µm)
• Z-axis: adjusts the vertical contact distance between the probe and the mouse
• Y-axis: adjusts lateral scanning of the mouse (manual, precision: 10 µm)

Note:The X and Y axes are equipped with graduated scales for locating the mouse scanning area; the Z-axis has no graduated scale.
