Minimally invasive surgery (MIS) has become the standard of care for a variety of surgical conditions, and reliable vessel sealing and precise cutting are essential. A variety of tissue-sealing devices have been used successfully to decrease operating time and control bleeding during hysterectomy and other MIS gynecologic procedures. One development involves the next generation of advanced bipolar devices by ETHICON (Ethicon Endo-Surgery Inc., Cincinnati, OH), called ENSEAL® G2 Tissue Sealers. Tip improvements to the ENSEAL® have included stronger jaws and a welded positive electrode in the stationary jaw, thus enabling the new ENSEAL® G2 Tissue Sealer to provide reliable vessel sealing and precise cutting all in the same instrument. The patented I-BLADE® forces the jaws of the device together as it advances, resulting in high, uniform compression along the entire length of the jaws. The temperature-regulating Positive Temperature Coefficient (PTC) material in the jaws is designed to minimize sticking, and the offset electrode configuration is designed to minimize thermal spread. The ergonomics provided by the ENSEAL® G2 Tissue Sealer offer significant improvement over previous devices and may make this a much more cost-effective choice for benign gynecologic procedures.
微创手术（MIS）已成为多种外科病症的治疗标准，可靠的血管封闭和精确切割至关重要。多种组织封闭设备已成功用于减少子宫切除术及其他MIS妇科手术的手术时间并控制出血。一项进展涉及ETHICON（俄亥俄州辛辛那提市的Ethicon Endo-Surgery公司）的下一代先进双极设备，即ENSEAL® G2组织封闭器。ENSEAL®的尖端改进包括更坚固的钳口以及固定钳口中焊接的正极，从而使新型ENSEAL® G2组织封闭器能够在同一器械中实现可靠的血管封闭和精确切割。专利的I-BLADE®在推进时将器械的钳口合拢，沿钳口全长产生高度均匀的压缩。钳口中的温度调节正温度系数（PTC）材料旨在最大程度减少粘连，而偏置电极配置旨在最大程度减少热扩散。ENSEAL® G2组织封闭器提供的人体工程学设计比以前的设备有显著改进，对于良性妇科手术而言，这可能使其成为更具成本效益的选择。
