An advanced bipolar sealing device delivers uniform compression across the entire length of the jaw, with a seal strength that withstands up to seven times normal systolic blood pressure.
The Enseal G2 Super Jaw is based on proprietary I-BLADE technology, designed for open surgical procedures such as colorectal, gynecological, and general surgery. Based on advanced bipolar technology, the device delivers high uniform compression for sealing vessels consistently along the length of the 40 mm curved jaw. A polymer compound within the jaw uses positive temperature coefficient (PTC) technology to modulate energy flow, thus maintaining a constant temperature of approximately 100 °C, minimizing tissue sticking, charring, and smoke.
The jaws contain a temperature-sensitive matrix with embedded conductive carbon spherules designed to "sense" tissue characteristics. It uses extremely high jaw compression to create uniform tissue effects. In addition, the G2 Super Jaw's offset electrode design focuses and contains energy within the jaws, minimizing thermal spread to approximately one mm. The Enseal G2 Super Jaw is a product of Ethicon Endo-Surgery (Blue Ash, Cincinnati, OH, USA).
"Surgeons need to be able to control heat and have effective seal compression from their advance energy devices while at the same time respecting the tissue," said Professor of surgery Clyde Neal Ellis, MD, of Temple University (Philadelphia, PA, USA). "Until the Enseal G2 Super Jaw, this was not possible with large jaw energy devices. Surgeons now have a technology that is strong on providing consistent compression through the seal and is gentle on tissue; there is no longer a need to compromise."
Vessel sealing devices (VSDs) promise less blood loss, less surgical time, and improved efficiency, but also have potential complications. VSDs acts by low constant voltage, pulsed high current, and impedance feedback. With high coaptive pressure, 100% hydrogen cross-links are first ruptured in the blood vessel, forming a firm vascular seal.
