So it isn’t accidental that the burns for the patient, during the electrosurgical interventions, have the shape of the edge neutral electrode. To reduce the burns risk have to dose opportunely the supply power (I2»t) and to follow the rules for the application of the neutral electrode on the patient (see cap. SAFETY). 2) Faradic Effect

Abstract

La diathermie 120 W a été inventée pour être installée dans tous les endroits qui fournissent des services médicaux tels que des hôpitaux, cliniques, unités de santé et ambulances équipées, et peut également devenir un substitut pour certains des outils médicaux destinés à des actes chirurgicaux anciens, tels que des scalpels médicaux et des outils de suture, l'ouverture de sites pour les opérations et également la fermeture des plaies et la cautérisation de celles-ci. Tous ces outils se réduisent désormais à ce dispositif qui peut pratiquer toutes ces opérations médicales à la fois.
