<p>A bipolar electrode for a resectoscope, comprising two metal sleeves (12), an insulating casing (11), a twin-core conductor wire (19), a semi-ring positive electrode (13), a loop electrode (14), two ceramic insulating tubes (15) and terminals (18). The front sections of the two metal sleeves (12) are branched and arranged at a distance; and the rear sections thereof are arranged to abut to each other side by side, and the insulating casing (11) is provided at the periphery of the rear section. The front ends of the two metal sleeves (12) are fixedly connected to the two ends of the semi-ring positive electrode (13) by means of the two insulating tubes (15) respectively, and the tail ends thereof are provided with the terminal (18). One conductor wire in the twin-core conductor wire (19) is electrically connected to the metal sleeve (12), and the other conductor wire penetrates into the metal sleeve (12) and is electrically connected to the positive electrode (13) at the front end. The loop electrode (14) comprises two metal tubes which are respectively arranged at the front parts of the two metal sleeves (12) and electrically connected to the metal sleeves (12), and the exterior of the rear sections of the two metal tubes of the loop electrode (14) and the front sections of the metal sleeves (12) are wrapped in an insulating layer sleeve (31). The bipolar electrode is safe and reliable, and has an improved operation effect.</p> |
