The combination particle and gas filter is used as part of a smoke evacuation system which reduces particulate and odour causing noxious chemicals from surgical smoke generated in laparoscopic procedures while maintaining a clear field of vision. It is indicated for use during any minimally invasive surgery involving insufflation, laser, or ultrasonic scalpel use. It is recommended that the surgeon and their team wear N95/FFP3 face mask during surgery.
A screening device installed within the suction tubing line of a suction system, or the suction tubing used with a central vacuum system, to extract particulates from the plume of smoke created typically through the use of various tissue-burning surgical devices (e.g., laser, electrosurgical diathermy device), to prevent clogging of the suction or vacuum system. It will typically have a hydrophobic membrane that retains the particulate/bacterial pathogens through a combination of mechanical, electrostatic, or other means. The device comes in various sizes and designs and can be made of translucent plastic, allowing for inspection when in use. This is a single-use device.
