Abstract:
A surgical micro-resecting instrument for use with an ENT procedure, the instrument comprising:an outer tubular member formed of an electrically conductive material and defining a proximal section, an intermediate section, a distal section, and an internal lumen, wherein the distal section forms a cutting window open to the lumen; an inner tubular member disposed within the lumen of the outer tubular member, the inner tubular member defining a proximal end and a distal end, wherein the distal end forms a cutting tip; a hub assembly maintaining the outer tubular member at the proximal section thereof and the inner tubular member at the proximal end thereof; wiring permanently electrically connected to the proximal section of the outer tubular member and adapted to deliver energy to the outer tubular member from a remote power source, wherein the electrical connection of the wiring to the outer tubular member is encompassed by the hub assembly; and an electrical insulator covering a region of the outer tubular member distal the hub assembly, wherein the cutting window is free of the insulator.
