Abstract

A method for determining a switch-off time of a medical instrument includes measuring the duration for which the temperature of a tissue is above 85° Celsius, preferably above 95° Celsius, calculating, preferably online, the mean temperature from the first time when 85° Celsius, preferably 95° Celsius is reached, measuring and/or calculating the energy input until 85° Celsius, preferably 95° Celsius, and preferably below 110° Celsius, preferably below 100° Celsius is reached, calculating a parameter SP, which links the above mentioned results, and switches off at a predetermined value. The method can be practiced with a medical instrument as well as an application and a storage medium.
