摘要：A surgical micro-resecting instrument including an outer tubular member, aninner tubular member, a hub assembly, wiring, and an electrical insulator. The outertubular member is formed of an electrically conductive material and defines a proximalsection, a distal section forming a cutting window, and an internal lumen. The innertubular member is disposed within the lumen and defines a proximal end and a distal endforming a cutting tip. The hub assembly maintains the outer tubular member and theinner tubular member. The wiring is permanently electrically connected to the proximalsection of the outer tubular member with the electrical connection being encompassedby the hub assembly. The electrical insulator covers a region of the outer tubularmember distal the hub assembly, at least the cutting window free of the insulator. In onepreferred embodiment, the hub assembly includes an outer hub insert molded to theouter tubular member, and forms a generally radially extending shroud.
