A successful endoscopic intervention depends upon ensuring proper working conditions, such as skilful camera handling, adequate lighting and removal of confounding factors, such as fluids or smoke. Smoke is an undesirable by-product of electro- or laser cauterization of the tissue to prevent or stop bleeding during a surgery. However, smoke does not only constitute a health hazard for the treated patient and the medical staff but it can also considerably obstruct the operating physician’s field of view. Therefore, the gaseous matter is removed by using specialized smoke evacuation systems that typically are activated manually. However, this action can easily be forgotten or neglected, potentially leading to a situation where the operating surgeon’s view is severely obstructed by smoke Although, there are some automated evacuation systems available, they depend on highly-specialized, operating room approved, and hence expensive, sensors. Additionally, automatic evacuation systems often start whenever the surgical device (e.g. a laser) is activated without checking if this is actually necessary (i.e., smoke is obstructing the surgeon’s vision). Unfortunately, such a simple evacuation strategy pressure loss which is problematic. Thus, modern smoke evacuation systems compensate this deficiency by inducing a surgical gas (e.g., CO2) in order to prevent bodily cavities from collapsing. In order to reduce the consumption of these gases it would be beneficial to limit the time that smoke evacuation takes place.
