摘要
An electrically-insulative shaft for an energy-based surgical instrument includes an outer tube formed from an electrically-insulative material, an inner tube formed from an electrically-insulative material, and an intermediate tube disposed between the outer and inner tubes. The intermediate tube is formed from an electrically-conductive material. Distal ends of the outer and inner tubes extend beyond a distal end of the intermediate tube and are joined to one another to enclose the distal end of the intermediate tube therebetween.
