ACTIVE SMOKE FILTRATION FOR INSUFFLATION

摘要

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.

主权项

1. A system for use during laparoscopic surgery, the system comprising:
a recirculation circuit having an inlet and an outlet, the inlet configured to connect to a body cavity and the outlet configured to connect to a gases conduit between a primary flow generator and a connection to the body cavity; a pneumatic isolation feature configured to be positioned between the recirculation circuit and the primary flow generator, the pneumatic isolation feature in fluid communication with the recirculation circuit; an active filtration unit positioned along the recirculation circuit, the active filtration unit comprising a flow generator portion and a filtration portion, the flow generator portion comprising an inlet and an outlet, the flow generator portion configured to create a pressure differential between the inlet and the outlet, the filtration portion comprising a filter adapted to remove smoke and other debris from a gases flow through the recirculation circuit; and a condensate management system positioned along the recirculation circuit.
