Generator control for a surgical instrument

A method treatment of the mucosa using an electrosurgical generator that operates an electrosurgical instrument, the method comprising:

• providing a control data set associating at least one preset treatment effect to a plurality of electrical variables of the electrosurgical generator;
• selecting one of the at least one preset treatment effect;
• initiating the treatment of the mucosa by the electrosurgical instrument;
• detecting the plurality of electrical variables during the treatment and determining a current tissue effect based on the plurality of electrical variables and the control data set;
• reducing a power output of the electrosurgical generator when the current tissue effect meets the selected one of the at least one preset treatment effects.

A method for generation of a control data set of a control module of an electrosurgical generator and subsequent operation of such a generator, the method comprising:

• during a training process, generating a training data set by influencing a biological tissue using the generator in a predefined setting and thereby provided or resulting electrical variables are determined as well as resulting tissue changes are recorded by means of an imaging device,
• assigning effect labels the tissue changes,
• determining a control data set from the training data set using machine learning, wherein the control data set represents a relation between the electrical variables and the effect labels,
• controlling the generator based on the control data set during an application procedure for attaining a desired effect corresponding to a selected effect label.
