1. A surgical apparatus, comprising:
- a surgical instrument including a housing and a cannula, and the cannula attached at a proximal end to the housing and defining at a distal end thereof an opening and the housing containing a drive interface; and
a surgical tool including a shaft, a tip, and the tip located in the opening, and the shaft contained within the cannula and the shaft defining a longitudinal annulus extending from a proximal end of the shaft to a distal end of the shaft, and the shaft mechanically coupled at the distal end to the tip, and at the proximal end, to the drive interface and the drive interface producing a surgical motion of the tip; and
a longitudinal member, including a proximal and a distal end, and the longitudinal member located within the annulus, and the longitudinal member extendable from an interior position in which the distal end is positioned within the tip to an exterior position in which the distal end extends beyond the tip, and is adapted to be energized in the exterior position to produce a cauterizing action at the tip.

Abstract
A surgical apparatus includes: a surgical instrument including a housing and a cannula; and a surgical tool including a shaft, and a tip, and a longitudinal member. The longitudinal member is contained within the shaft and is extendable from an interior position to an exterior position in which it is energized in the exterior position to produce a cauterizing action at the tip.

14. A cutting and cauterizing device for connection to a surgical instrument including a drive interface and a first interconnector, the cutting and cauterizing device comprising:
-
a cannula defining at a distal end thereof an opening; a second interconnector, suitable for switchably coupling to a power supply, and the second interconnector located at the proximal end of the cannula and shaped to couple to the first interconnector; and a surgical tool including a shaft and a tip, and the tip located in the opening, and the shaft contained within the cannula, and the shaft defining a longitudinal annulus extending from a proximal end of the shaft to a distal end of the sheet, and the shaft coupled at a distal end to the tip and at a proximal end adapted to be mechanically coupled to the drive interface to permit a surgical motion of the tip, a longitudinal member, including a proximal and a distal end, and the longitudinal member located within the annulus, and the longitudinal member extendable from an interior position in which the distal end is positioned within the tip to an exterior position in which the distal end extends beyond the tip, and is adapted to be energized in the exterior position to produce a cauterizing action at the tip. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 25)
