The localization principle of stereotactic intracerebral hematoma removal with hose suction is based on a three-dimensional coordinate system, where the position of any point in space can be determined by a three-dimensional directional coordinate system. Stereotactic intracerebral hematoma removal with hose suction uses mutually perpendicular locators of varying lengths to identify any target point in the skull with reference to the stereotactic parameters provided by the CT scan. The present technique uses the stereotactic localization parameters provided by the CT scan, and then any intracranial target can be identified. The present technique uses the level of the CT scan as the horizontal plane, the anterior-posterior median of the skull as the sagittal plane, and the locator to determine the coronal plane of the human brain, and the above three planes as the base standard plane for localization. In this way any point in the brain can be located by the intersection of these three reference planes. Thus for intracerebral hemorrhage, the central target point of the hematoma can be determined by the three mutually perpendicular planes and the projection of the morphology of the intracerebral hematoma in the prefrontal, temporal and parietal and occipital regions of the skull. The straight line formed by the intersection of any two of the three mutually perpendicular planes can be used as the path of entry, and the position of the other plane is used as a marker of the depth of entry, so that the target point can be reached accurately.
