The invention discloses an intracranial hematoma puncture drainage locating device and locating method, and relates to a locating device and a locating method. The locating device mainly comprises a fixing shell, support legs, a drainage tube, a movable locating block, a suction disc, a locating syringe, a locating bolt, a heating button, an extension type screw, an inflating bag, an inflating tube, an inflating valve, a heat preservation button, a thermometer, a syringe needle connecting sleeve, a thread hole, and a connecting tube. The intracranial hematoma puncture drainage locating deviceovercomes the defect of low puncture accuracy rate in the prior art, the puncture time is short, and the pain of a patient is effectively reduced. After the locating method provided by the invention is used to locate intracranial hematoma puncture drainage, the elimination rate of hematoma is greatly improved and is 97.8%, the total effective rate is up to 97%, the difference value of the neural functional recovery is obviously better than that of the prior art, and the viability of a postoperative patient is also greatly strengthened.
