摘要：
A smoke evacuator system includes a regulator device configured for coupling to a vacuum source for evacuating smoke from a laparoscopic field within the body of a patient. The regulator device is pneumatic-operated and configured to continuously monitor pressure of insufflation gas within the laparoscopic field and to automatically apply suction from the vacuum source to the laparoscopic field when the pressure monitored reaches a preset level, whereupon smoke within the laparoscopic field is evacuated from the laparoscopic field. In one embodiment the smoke is evacuated via a conventional trocar. In another embodiment, where the laparoscopic field is confined, the smoke is evacuated by means of a smoke probe.
