Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a cranial puncture positioning device. Background Art

[0002] Brain puncture is often used in clinical practice. Brain puncture needs to clarify the specific condition at the time. If it is cerebral hemorrhage, the choice is CT-guided intracranial hematoma puncture and drainage surgery, while if it is acute hydrocephalus, the choice is external ventricular puncture and drainage surgery; CT-guided intracranial hematoma puncture and drainage surgery is a very popular minimally invasive surgery in recent years. It often only requires minimally invasive drilling under the guidance of CT positioning, and placing a catheter in the hematoma cavity can properly remove the intracranial hematoma; this type of surgery has relatively few complications and trauma, and is suitable for elderly patients or patients with less bleeding, and has good effects; and external ventricular puncture and drainage surgery is mainly suitable for the formation of acute hydrocephalus, which requires immediate drainage of intracranial hydrops to reduce the state of intracranial hypertension, and is a treatment model for saving patients' lives;

[0003] In summary, the current cranial puncture process has the following technical problems: in various surgical situations, the puncture site of the patient's brain needs to be measured and selected. With the assistance of imaging, doctors can plan the puncture point on the established model, but in actual operation, because the head is not a perfect sphere, the puncture point can often only be roughly measured, which is slightly different from the actual planned puncture position.
