P129
Electrocautery (designed by Bovie with Cushing for neurosurgery in the 1920s)
What is the CUT mode on the Bovie?
P129
Continuous electrical current (20,000 Hz); cuts well with a decreased ability to coagulate
What is the COAG mode on the Bovie?
P129
Intermittent electrical current (20,000 Hz); results in excellent vessel coagulation with decreased ability to cut
Where should a Bovie be applied to a clamp or pickup to coagulate a vessel?
P129 (picture)
Anywhere on the clamp/pick-up
