What type suction is used during craniotomy?

During a craniotomy, a suction device known as a "neurosurgical suction" or "cavitron ultrasonic surgical aspirator (CUSA)" is typically used. This type of suction allows surgeons to remove blood, fluids, and tissue with precision while minimizing damage to surrounding structures. The suction may be equipped with varying tips and settings to adapt to different surgical needs. Overall, the goal is to maintain a clear surgical field and enhance visibility during the procedure.
