An experimental study was performed on Wistar rats with the purpose of histological evaluation of the surgical wounds state and the processes of their healing using a conventional surgical scalpel and three radio wave devices with different operating frequencies (2.2 MHz, 2.64 MHz, 3.8 MHz). It has been established that in animals with wounds inflicted by the radio-wave at the highestworking frequency, there were statistically significant differences both in terms and in the mechanisms of wound healing. These benefits were in the absence of a blood clot in the wound after the incision, also in minimal necrosis of the operating wound and adjacent tissues, in the absence of leukocyte infiltration in the wound; early (from 3 days) reparation and epithelialization of tissues. These features contributed to a reduction in the timing of wound healing and the absence of scar formation.

© 2018 Authors. The present work presents a description of various cutting devices with an emphasis on skin surgery for the optimal choice of instruments in plastic surgery. Physical principles of work with a description of the biological role of an ultrasonic scalpel, various laser cutting devices, electrosurgical instruments, including radiofrequency electrosurgery, are described. Studies of recent years, including systematic reviews and meta-analyzes, are devoted to comparative analysis of various cutting and coagulating devices among themselves and in comparison with the mechanical metal scalpel.
