S-PILOT® – The Comprehensive and Automatic Solution for Smoke Evacuation

As an early pioneer in laparoscopy, KARL STORZ has consistently worked to advance the state of the art. A great example is the S-PILOT® modular smoke evacuation management system, with in-line filtration and options for both active and passive applications. Recent guidance from SAGES and EAES recommends "For MIS procedures, use of devices to filter released CO2 for aerosolized particles should be strongly considered".
While KARL STORZ has not specifically tested the use of KARL STORZ smoke evacuation devices and SARS-CoV-2, there are data on KARL STORZ filters and its effectiveness against other bacteria and viruses.
The filter efficiency of KARL STORZ filters was tested using the most common test methods with microorganisms known as "Virus Filtration Efficiency (VFE)" and "Bacterial Filtration Efficiency (BFE)". These types of tests are considered to be the most similar to clinical scenarios. A test aerosol with a mean particle size of 3 +/- 0.3 µm and a virus bacteriophage ɸX174 of 0.027 µm (at VFE) or bacteria Staphylococcus aureus (at BFE) were used. Test results confirmed a filter efficiency of more than 99.9999 %.
The Most Penetrating Particle Size is typically in a range of 0.1-0.3 µm. These particles are the most difficult to trap by the filter. The test aerosol DEHS (= Di-2-Ethylhexyl-Sebacat) with a size of 0.3 µm was therefore used for non-microbiological tests. A filter efficiency of more than 99.9994 % was achieved.
