Abstract
The present invention reliably provides a lung protection function for an electrocautery device by unitizing an automatic bovie activation/inactivation unit. The lung protection unit utilizes a threshold calculated from the maximum and minimum airway pressure signal in a ventilator or an anesthesia machine to inactivate the bovie before the maximal lung expansion reaches the bovie during a thoracic surgery. Bovie is activated again as soon as the lung expansion level decreases to below the threshold level. This device is an attached optional unit or can be built into a standard electrocautery equipment.
