The present review aims to analyze the current information on basic principles, applications, advantages and risks of the main surgical devices used in laparoscopic surgery. A comprehensive review of literature was made of existing English language publications on databases Pub med and Google Scholar following a Mesh and key word searching. The studies were finally selected by one author according to the aim of this review. Currently, different kinds of devices using electrical, mechanical, plasma and ferromagnetic heat energy are available in laparoscopic surgery. New advanced bipolar instruments, using a tissue impedance measure, vessel sealing technologies and positive temperature control allows the surgeon an effective, safe and faster surgery, with less thermal spread. Ultrasound apply to surgery offer the surgical team (using a combination of high speed mobilization and cavitation principles) a faster and safest surgery parameters, but with the highest device tip heating. Thunder beat™ is a unique instrument that combines the cutting efficiency of the ultrasound with the coagulation advantages of bipolar energy and appears to be the fastest and more versatile device available. Using ionized inner gas with minimal electricity flow, plasma devices allows cutting, coagulation and fulguration in the same instrument, but probably with the higher thermal spread among all. Employing pure thermal heat due the conduction of radio-frequency current, ferromagnetic heat energy devices are the newest instruments that can safety seal vessels up to 7 mm.

Apyx Medical manufactures and owns the Renuvion®/J-Plasma® technology discussed in this article.


  • The Renuvion Precise, Precise Open, and J-Plasma Handpieces are intended to be used with compatible electrosurgical generators for the delivery of radiofrequency energy and/or helium plasma for cutting, coagulation, and ablation of soft tissue during open surgical procedures.
  • Apyx Medical wants to present to you with current scientific discourse.


  • Risk associated with the use of the device may include: Helium embolism into the surgical site due to inadvertent introduction into the venous or arterial blood supply system, unintended burns (deep or superficial), pneumothorax, temporary or permanent nerve injury, ischemia, fibrosis, infection, pain, discomfort, gas buildup resulting in temporary and transient crepitus or pain, bleeding, hematoma, seroma, subcutaneous induration, pigmentation changes, increased healing time, and/or unsatisfactory scarring. There may be additional risks associated with the use of other devices along with Renuvion/J-Plasma and there may be an increased risk for patients who have undergone prior surgical or aesthetic procedures in the treatment area.

As with any procedure, individual results may vary. As with all energy devices there are inherent risks associated with its use, refer to the IFU for further information.
