0390937-A1 is referenced by 206 patents and cites 4 patents.

The invention relates to a device for monitoring the application of neutral electrodes with at least two separate contact surfaces (2, 3) on the patient during high-frequency surgery. Warning signals and/or automatic switching-off of the high-frequency generator (17) occur when and only when the high-frequency current for cutting and/or coagulation is greater than that permitted in the electrical conductance present in each case between neutral electrode and the skin of the patient, without risk of thermal damage to the skin at the application site of the neutral electrode.

Title
Device for the surveillance of the adherence of neutral electrodes in high-frequency surgery.
