Electrosurgical vessel sealing is used throughout many surgical procedures with the benefits of the device widely reported. However, there is still significant variation in the quality of the resulting seal with limited understanding as to why. This study developed a methodology to use digital image correlation to capture the sealing process and to investigate the changes occurring throughout. ...

BACKGROUND AND OBJECTIVES Pancreatic cysts are evaluated by endoscopic ultrasound and fine needle aspiration (EUS). The only accepted treatment is pancreatectomy, which is associated with morbidity and mortality. This study evaluated the optimal thermal dosimetry of a novel radiofrequency ablation device using a standard electrosurgical unit in ex vivo cyst models. METHODS A modified EUS 22-g...

The issues of determining the output power high-frequency electrosurgical equipment by simulation single fault conditions in accordance with particular standard DSTU EN 60601-2-2:2015 are considered. It is noted that modern equipped measuring units to control current and voltage order ensure power. A method for monitoring performance built-in protection systems HF proposed if exceeds limits all...

BACKGROUND AND OBJECTIVES After being encouraged to change the technique for opening the vaginal cuff during robotic surgery, this study was performed to determine the correlation between vaginal cuff complications and electrosurgical techniques. METHODS The study group consisted of patients who had their vaginal cuffs opened with a cutting current compared to the group of patients having the...
