“…This is why other types of tissue incision, known and approbated in human medicine, are becoming more common in veterinary practice. Various electrosurgical devices mentioned in the literature were widely introduced in human medicine only at the beginning of this century and still are considered to be an integral part of modern surgery worldwide (Vogt, 2008;Taheri et al, 2014).…”

The purpose of using electrosurgical devices in veterinary practice is to reduce bleeding during the cut increasing temperature locally, causing coagulation and apoptosis of proteins. There is a lack of data on the extent and depth of these thermal damages and whether these effects on the different tissues are the same. Because of that, the aim of this study was to investigate which of the different electrosurgical devices causes highest heating effect on the skin tissue of rabbits (Oryctolagus cuniculus). The research was carried out at the Latvia University of Life Sciences and Technologies, Faculty of Veterinary Medicine. It included 50 rabbits, on average 2 years old, clinically healthy, with similar weight and condition. We formed five experimental groups: skin tissue cut with CO 2 laser (n=10), an electrocoagulator (n=10), a tissue welding device (n=10), a radiofrequency apparatus (n=10) and a scalpel as control group (n=10). In order to evaluate the thermal effects of electrosurgical instruments on tissues, we performed contactless thermography. There were taken 3 images for each animal, totally 150 skin thermo-gramms. From the obtained results we conclude that the most pronounced thermal effect on rabbit's skin was caused with laser and an electrocoagulator. All electrosurgical devices caused a significantly higher (p<0.01) increase in skin temperature compared to a surgical scalpel at the moment of tissue incision. During the study, it was found that the gentlest electrosurgical devices used on rabbit skin tissue was a radiofrequency device.

“…Heat generation and thermal tissue damage are the cause of the obtained electrosurgery effect. The only variable that determines the ultimate current effect on the tissue is the depth of affected tissue and the rate of heating (Taheri et al, 2014;Haneke, 2015).…”

“…15 Many complications are based on the faulty use of the instruments and settings; therefore, knowledge and basic skills in operating these devices are of great importance. However, while surgeons and surgical trainees may use energy-based devices on a daily basis, they are not always familiar with their basic principles and functions.…”

The benefits of electrosurgery have been acknowledged since the early 1920s, and nowadays more than 80% of surgical procedures involve devices that apply energy to tissues. Despite its widespread use, it is currently unknown how the operator’s choices with regard to instrument selection and application technique are related to complications. As such, the manner in which electrosurgery is applied can have a serious influence on the outcome of the procedure and the well-being of patients. The aim of this study is to investigate the variety of differences in usage of electrosurgical devices. Our approach is to measure these parameters to provide insight into application techniques. A sensor was developed that records the magnitude of electric current delivered to an electrosurgical device at a frequency of 10 Hz. The sensor is able to detect device activation times and a reliable estimate of the power-level settings. Data were recorded for 91 laparoscopic cholecystectomies performed by different surgeons and residents. Results of the current measurement data show differences in the way electrosurgery is applied by surgeons and residents during a laparoscopic cholecystectomy. Variations are seen in the number of activations, the activation time, and the approach for removal of the gallbladder. Analysis showed that experienced surgeons have a longer activation time than residents (3.01 vs 1.41 seconds, P < .001) and a lower number of activations (102 vs 123). This method offers the opportunity to relate application techniques to clinical outcome and to provide input for the development of a best practice model.

“…Electrosurgery is widely used for different surgical procedures, for example, cutting of tissue, resection of tumours, ablation of tissue and coagulation of tissue and blood vessels . A handheld instrument with an active electrode that is of the size of a needle, in this work named “electric scalpel”, and a passive electrode with a larger contact area are connected to a conventional electrosurgical unit (ESU), which is a radio frequency (RF) generator.…”

“…The advantage of this procedure compared to a normal scalpel is a minimal blood loss due to thermal coagulation of blood vessels. Because of tissue vaporisation in the vicinity of the needle electrode a gap is formed and since (high enough) RF voltage is applied, a discharge is ignited in this gap . The molecules and atoms of the vaporised tissue are excited by electron impact and thereby (a lot of) molecular bands and atomic lines can be observed in the emission spectrum.…”

Electric scalpels are used for cutting of biological tissue, for example, for resection of tumour tissue in surgery. During the electrosurgical procedure a plasma is ignited in a gap between the electric scalpel and the tissue. In this study, the plasma operated on porcine kidney and a tissue substitute (cellulose impregnated with isotonic saline) is characterised by means of voltage‐current measurements, microphotography, optical emission spectroscopy and numerical simulation. The molecular emission of nitrogen is used for the determination of the gas temperature and the reduced electric field. The electron density is determined using the measured electric current density.
