Abstract
An active smoke filtration unit is used to remove smoke during laparoscopic surgery. The active smoke filtration unit is part of a recirculation circuit. The recirculation circuit is pneumatically isolated from a primary flow generator, such as an insufflator, by a valve assembly. The active smoke filtration unit can be housed separately from the valve assembly or together with the valve assembly. The recirculation circuit can include a humidifier to heat and humidify the insufflation gases.
