[0002] Cerebrovascular disease seriously threatens human health, has high disability rate and high mortality rate characteristics, in the neurology department cerebrovascular treatment, head blood vessel intervention operation is with the advantage such as small trauma, quick recovery, plays the key role in the diagnosis and treatment in cerebral aneurysm, cerebrovascular malformation, acute ischemic cerebral stroke, in this kind of operation, accurate puncture to target blood vessel, not only is the basis of obtaining accurate diagnostic information, is the key to determine whether the subsequent treatment scheme can be smoothly implemented, the treatment effect can reach the standard. Therefore, high-precision puncture positioning equipment is indispensable, however, the head blood vessel intervention puncture positioning equipment of present stage has many problems, seriously restricts the safety and effectiveness of operation.

[0003] The traditional puncture positioning equipment adopts the positioning assembly in the positioning rod or positioning cylinder for positioning in the positioning process. Specifically, the end of the positioning rod or positioning cylinder is extended to the puncture site on the head, and then fixed and installed on the external frame body through a fastening screw to realize positioning. In this process, the doctor needs to repeatedly adjust the position and angle of the equipment, and the operation steps are multiple and complex. Each adjustment needs to recalibrate the equipment parameters, which not only consumes a lot of time, but also may need to be adjusted again due to inaccurate positioning. The prolongation of the operation time not only increases the patient's pain, but also exposes the patient to radiation for a long time during the operation, increases the risk of infection, and causes double burden on the patient's physiology and psychology. In addition, some positioning uses adhesive tape for positioning operation. The cross-shaped adhesive tape is adhered to the corresponding position. The intersection of the cross-shaped adhesive tape is the puncture site. However, the width of the adhesive tape is small, and it cannot be fixed for a long time. In addition, the adhesive tape has small adhesion and is easy to fall off. In view of this, we propose a head blood vessel intervention puncture positioning equipment. UTILITY MODEL CONTENTS
