Description

Technical Field

[0002] Electric craniotomy drills are commonly used surgical instruments in modern neurosurgery, characterized by efficiency, precision, and safety. They are usually equipped with high-speed motors, which can quickly penetrate the skull while reducing surgical time.

[0003] During neurosurgery craniotomy, the doctor needs to accurately locate the area that needs to be drilled based on preoperative imaging examinations in advance, mark the specific location on the patient's head, and select a suitable drill bit according to the surgical site. Then, hold the handle tightly, turn on the power, and start the electric craniotomy drill. After the drill bit contacts the skull surface, keep the drill bit perpendicular to the skull surface, gradually increase the pressure, and observe the position of the drill bit and the thickness of the skull at any time.
