Craniotomy

A craniotomy is when a neurosurgeon drills into the skull of a patient in order to get access to their brain to remove a tumor, relieve pressure, or other reasons.

The procedure starts with taking a CT or MRI scan of the patient's head. This helps the surgeon precisely locate the angle where he has to cut and the location. Then, the head is prepared. The neurosurgeon will cut the hair around the area where the surgery will take place. Then, the surgeon will cut into the scalp and hit the skull. The high tech neurosurgery drill will be used to remove part of the skull flap. It will be replaced later.

This is a high tech neurosurgery drill.

Here are some instruments designed for precision in neurosurgery.
