This lecture provides a comprehensive overview of the bipolar shearer (seal-and-cut device) used in gynecologic laparoscopic surgery. It explains the scientific principles behind tissue sealing and cutting, followed by a detailed description of the instrument, generator settings, and operating technique. Multiple operative videos demonstrate its application in hysterectomy, myomectomy, retroperitoneal dissection, ovarian surgery, and uterine artery ligation. The advantages of reduced instrument exchanges, efficient hemostasis, and precise dissection are highlighted. The lecture concludes with a balanced discussion of the device's limitations, learning curve, cost, and comparison with other energy sources.
