DUAL MODE LASER SMOKE EVACUATION SYSTEM WITH SEQUENTIAL FILTER MONITOR AND VACUUM COMPENSATION |
摘要 |
A surgical laser smoke evacuation system includes a sensor positioned at the surgical site to determine the need for evacuation. A vacuum pump draws smoke from the site through a system of conduits, including an in line filter. The filter tends to become clogged over time. A sensor determines changes in the pressure drop across the filter, and is connected to a control mechanism which adjusts the speed of the vacuum pump to maintain an approximately constant flow across the filter.
