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.

Claims

1. An integrated surgical and cauterizing apparatus, comprising:

a surgical instrument including a drive member, a cannula, and a tool, the cannula being attached at a proximal end to the drive member and defining at a distal end thereof an opening, the tool including a shaft and a tip, the shaft being contained within the 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 a first electrode, a first conductor, a first second clamp dimensioned to affix the first electrode to the cannula, and a second clamp dimensioned to affix the first conductor to the cannula, the first electrode being affixed to the cannula adjacent to the distal end of the cannula and the first conductor providing an electrical path from the first electrode for application of electrical power to the first electrode to produce a cauterizing effect.

2. A cauterizing instrument for attachment to a surgical instrument including a cannula, the cauterizing instrument comprising:

a first electrode adapted to be affixed to the cannula adjacent to a distal end of the cannula;

a first conductor providing an electrical path from the first electrode for application of electrical power to the first electrode to produce a cauterizing effect;

a first clamp dimensioned to clamp the first electrode to the cannula; and

a second clamp dimensioned to clamp the first conductor to the cannula.
