First Claim
Patent Images
1. An electrosurgical suction coagulator, comprising:
- a handle having an elongated tube electrode extending from a distal end thereof, said elongated tube electrode including;
a substantially blunt and closed distal end;
an elongated slot disposed therethrough that slidingly receives a needle electrode, said needle electrode being selectively extendible relative to said closed distal end;
at least one aspiration port disposed along a side of the elongated tube electrode, wherein the at least one aspiration port is chamfered; and
a selectively activateable valve operable to regulate the flow through said aspiration port, said valve including a generally arcuate sleeve that is rotated within the elongated tube electrode to regulate the flow through said aspiration port.

Abstract
An electrosurgical suction coagulator includes a handle having an elongated tube electrode or conductive suction tube extending from a distal end of the handle. The elongated suction tube includes a substantially blunt or closed distal end and an elongated slot disposed therethrough for slideably receiving a needle electrode. The needle electrode is selectively extendible relative to the closed distal end to facilitate precise dissection. When retracted, the user can use the closed distal end for spot or blunt coagulation. At least one aspiration port is disposed along a side of the elongated suction tube for removing surgical fluids from the operating area.
