主权项

1. A cautery assembly comprising:
a shaft; an insulation ring that:
has a ribbon shape;is formed at least in part by an electrical insulator;extends in a ring loop emanating from the shaft; andis progressively expandable from and retractable into the shaft, thereby increasing and decreasing the ring loop's size, respectively; and a cautery wire that:
comprises an electrical conductor;forms a wire loop emanating from the shaft; andis progressively expandable from and retractable into the shaft independently of the ring loop, thereby increasing and decreasing the wire loop's size, respectively.
