A recently granted patent (Publication Number: US11911100B2) discloses a rapid pulsatile smoke extraction system designed for controlling smoke during tissue treatment procedures. The system comprises a laser that provides energy to a handpiece, a reservoir with a smoke and particulate filter connected to a vacuum pump via tubing, and a valve between the handpiece and the reservoir. The reservoir's filter is a single element that supports a vacuum and effectively filters odors, viruses, and particulates from the air drawn in by the vacuum pressure.

Furthermore, the patented system allows the laser to operate in a pulse mode with laser pulses lasting from 1 microsecond to 100 milliseconds. Additionally, the laser can also operate in a quasi-continuous mode, providing flexibility in the treatment procedures. The vacuum pump in the system has a flow capacity ranging from 0.5 liters per minute to 1000 liters per minute, ensuring efficient smoke extraction during the tissue treatment process. This innovative system addresses the need for effective smoke control in medical procedures, enhancing safety and efficiency in tissue treatment.
