“…Following careful control of the electrosurgical procedures, a small area of denaturalization, produced by lateral heat, is always found in the trajectory adjacent to the incision. This area did not appear to affect the the stages of cicatrization of the wound and usually disappears over a period of two weeks 15 . The immediate response of the connective tissue was not evaluated in this study, although at 3 days there was less fibroblastic proliferation in the electrosurgery group.…”

PURPOSE: To compare tissue cicatrization in the tongue of rats using electrosurgery and the cold blade. METHODS: Ten adult male Wistar rats were divided into two groups of 5 animals each, according to the time of sacrifice (3 and 7 days). Each animal had two incisions, one made with a cold blade and the other with an electric blade, both of which were approximately 0.5 mm in length. Following sacrifice of the animals, the tongues were submitted to a histological study in order to classify the presence of angiogenesis, fibroblastic proliferation, epithelial proliferation and inflammatory cells as good, moderate and weak. RESULTS: The wound made with electric blade presented a delay in the healing process and a greater inflammatory response as compared with the cold blade, despite the fact that there was no statistically significant difference (p<0.05). CONCLUSION: There were no significant statistical differences between electrosurgery and the cold blade in relation to angiogenesis, fibroblastic proliferation, epithelial proliferation or the presence of inflammatory cells at any time of evaluation.

“…As laparoscopic surgery becomes evolved, the use of electrosurgical instruments is able to achieve reliable and rapid sealing of blood vessels and tissues [6]. However, current technologies still present limitations such as collateral tissue damage and surgical smoke generation [2][3][4]. Previously, laparoscopic energy-based devices with various sealing mechanisms, including bipolar electric current (e.g., LigaSure™), ultrasonic energy (e.g., Harmonic Scalpel™), and nanotechnology (e.g., EnSeal PTC™), have been studied.…”

“…The majority of conventional bipolar energy-based vessel sealing devices utilize energy at frequencies between 300 kHz and 500 kHz. The use of such frequencies has the disadvantage of possible energy transfer to a wide area to cause unintended damage to surrounding tissues [2]. In addition, in the laparoscopic surgical environment, unnecessary energy transfer inevitably produces surgical smoke that compromises the visibility of surgeons and generates binding between the instrument and tissue [3,4].…”

Background: The majority of conventional bipolar energy-based vessel sealing devices utilize energy at frequencies between 300 kHz and 500 kHz. The use of such frequencies has the disadvantages including unintended damage to surrounding tissues and excessive surgical smoke production. Here, we developed an bipolar energy source using Quantum Molecular Resonance (QMR) energy of 4–64 MHz and combined this into a laparoscopic vessel sealer. We investigate the microscopic tissue effect and surgeon's experiences of laparoscopic bipolar vessel sealer using a novel QMR energy source through animal experiments. Results: In an open surgical setting, QMR energy sources showed higher sealing success rates (100% vs. 66.7%) and higher burst pressure (963 mmHg vs. 802mmHg) of the sealed vessels compared to LigaSure™. Histological analysis showed less vessel wall injury in the QMR energy source (55.0% vs. 73.9%). In the laparoscopic setting experiments, compared to LigaSure™, QMR energy sources showed statistically significantly less smoke formation (p = 0.014), less tissue carbonization (p = 0.013), and less stickiness (p = 0.044) during sealing tissues. Conclusions: Novel QMR energy source for laparoscopic bipolar vessel sealer could produce better sealing performance and less surrounding tissue damage compared to the conventional devices. Laparoscopic surgery using QMR energy sources showed better surgeon's experiences in terms of surgical smoke formation, tissue carbonization, and stickiness.
