 · The father of laparoscopic surgery in Europe was Raoul Palmer (1905–1985) (), who delineated its role in both infertility and birth control and pioneered laparoscopic tubal occlusion using electrocoagulation .Palmer, who was head of the gynecological clinic at the Broca Hospital in Paris, had a leading role in the fight for contraception and termination of pregnancy in France in the 1960s .

Electrosurgery: Principles, Biologic Effects and Results

Blended currents are created by modulating a second, lower frequency, higher amplitude sine wave with the sine wave from the cutting generator, producing a higher peak-to-peak voltage. The new waveform is then delivered in intermittent bursts at a rate determined by the settings of the electrosurgical generator ( i.e., Blend 1) (Fig. 4).

High voltage/high frequency electricity is not infrequently responsible for abdominal wall burns and perferating the bowel. During electrosurgery, the coagulating electrode is in close proximity to surrounding tissues and other operative instruments. It is not uncommon for the coagulating tip to obliterate the blood supply to the ovary.

The intensity of magnetic fields around high-voltage systems, which was about 46.75 mG at the distance of 10 cm, was the highest among measured electromagnetic fields. Conclusions The highest magnetic field intensity measured in this study was related to high-voltage systems and is lower than advised intensity by ICNIRP for occupational exposure.

RADIATION SAFETY | RLS HUMAN CARE

 · The main hazards from high voltage lines and equipment (low frequency) are shocks and current. Extremely low frequency (ELF) radiation produces an electric field and magnetic field. An external electric field induces an electric current in the body. Protection from ELF is possible by shielding of the electric field by any conducting surface.
