  • Patent number: 6007533
    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.

  • Patent number: 6004320
    Abstract: Disclosed is an integrated surgical and cauterizing apparatus, comprising a surgical instrument including a drive member, a cannula, and a tool, and the cannula attached at a proximal end to the drive member and defining at a distal end thereof an opening, and the tool including a shaft and a tip, and the shaft contained within he cannula and connecting the tip in the opening of the cannula to the drive member to produce a surgical motion of the tip; and a cauterizing instrument comprising at least one electrode, and a conductor, and at least one electrode affixed to the cannula adjacent to the distal end of the cannula and the conductor providing an electrical path from the at least one electrode for the application of electrical power to the at least one electrode to produce a cauterizing effect.

  • Patent number: 5290282
    Abstract: A coagulating cannula is described which effectively operates in a localized area quite rapidly, without the need for removal of motorized shaving instruments, by the incorporation of a selective manually operative electrocautery positioned at a distal end of the shaft of the cannula. The cannula incorporates a nonconductive cylindrical hollow shaft and a nonconductive hub portion through which the motorized shaving instruments are inserted and removed. The electrocautery component enters the cannula at an electrical contact which protrudes from an outer surface of the hub portion and continuously runs within the hub and into a wall of the shaft terminating at the distal end of the shaft in a prominance at the tip of the shaft. The prominance is of a small surface area such that the prominance provides a small electrical contact area with a surrounding saline environment, thereby providing a high resistance arcing to the surrounding tissue that needs to be coagulated.
