The anterior horn of the lateral ventricle is punctured by positioning 2.5cm in front of the ipsilateral coronary seam and opening 2.5cm aside to form a puncture point, aiming at a connecting line of double external auditory canals, puncturing in parallel with a midline, and measuring the depth before an operation according to requirements. In the above-mentioned conventional puncturing process, all techniques are quantized, and the only technology that cannot be quantized is the puncturing direction: when puncturing, a needle point points to an eyebrow center or an external auditory canal connecting line, an operator cannot directly view the connecting line in the direction and can only imagine that the precision is difficult to ensure, if the direction is wrong, puncturing failure can be caused, the position of a drainage tube is inaccurate, or an important deep brain structure is accidentally injured, even bleeding is caused, serious complications are generated, similarly, in order to ensure that the puncturing is directly pointed to a preset position, a long learning curve is needed, the puncturing direction is easy to deviate, and finally, the puncturing cannot reach a ventricle or even injure a thalamus structure. The intracranial hematoma puncture is also the same, most of the common puncture points used as the puncture points of the hypertensive cerebral hemorrhage can be well punctured and placed into a hematoma cavity according to the puncture angle and depth, but if the bleeding part is not the common cerebral hemorrhage position or the experience of an operator is not sufficient, the CT positioning before the operation is adopted, a simple auxiliary positioning puncture device which can be utilized is provided, and the success rate of first puncture and tube placement can be ensured to a greater extent. At present, a stereotactic frame is adopted to assist puncture or preoperative CT scanning and backward 3D printing puncture catheter to ensure the stability of puncture direction, but the equipment requirement is high, and the individual difference also needs extra 3D editing and printing requirements and consumable material requirements, so that the puncture catheter cannot be popularized in a large range.
