Coagulation Instruments
摘要
Monopolar coagulation instruments are fundamental to laparoscopic surgery, enabling effective haemostasis, tissue dissection, and precise cutting. These instruments—including the hook, spatula, ball-tip, and needle electrode—operate by transmitting high-frequency electrical current from an electrosurgical unit through an active electrode to the target tissue, generating localized thermal effects. Each instrument is uniquely designed to optimize specific surgical tasks, ranging from fine dissection to broad-surface coagulation. While monopolar energy offers versatility, precision, and ease of use, it requires meticulous handling to prevent complications such as unintended thermal injury, insulation failure, and return electrode burns. Proper understanding of instrument design, applications, troubleshooting, and maintenance is essential for safe and effective use. Despite the availability of advanced energy devices, monopolar instruments remain widely used due to their cost-effectiveness and adaptability, making them indispensable in both routine and complex laparoscopic procedures.
