| 20100205802 | Two Piece Tube for Suction Coagulator - A method of manufacturing an electrosurgical tool includes the initial step of coupling a proximal end of a substantially malleable elongate tube-like shaft to a distal end of a housing. A tub-like dielectric sheath is disposed on the tube-like shaft. The method also includes the steps of coupling a tube-like electrode having a first thermal conductivity K | 08-19-2010 |
| 20100211069 | Two Piece Tube for Suction Coagulator - An electrosurgical suction coagulator includes a housing having proximal and distal ends. An elongated tube-like shaft extends longitudinally from the distal end of the housing. The elongated tube-like shaft includes a tube-like dielectric sheath and a tube-like electrode disposed coaxially through the tube-like dielectric sheath. The tube-like electrode couples to a source of electrosurgical energy. A proximal end of the tube-like electrode couples to a source of suction. An electrically conductive distal tip is mechanically coupled to a distal end of the tube-like electrode and is in electrical communication with the tube-like electrode. The electrically conductive tip protrudes from a distal end of the tube-like shaft and has one or more aspiration ports defined at its distal end. The electrically conductive distal tip is made from a material having less thermal conductivity than the tube-like electrode such that the electrically conductive distal tip impedes the propagation of thermal energy proximally. | 08-19-2010 |
| 20100324555 | Thermal Barrier for Suction Coagulator - An electrosurgical suction coagulator includes a housing having proximal and distal ends and a substantially malleable elongated tube-like shaft extending longitudinally from the distal end of the housing. The elongated tube-like shaft includes a tube-like dielectric sheath and a tube-like electrode disposed coaxially through the tube-like dielectric sheath. The tube-like electrode is configured to operably couple to a source of electrosurgical energy and a proximal end of the tube-like electrode is adapted to operably couple to a source of suction. The tube-like shaft also includes a thermally conductive member. The thermally conductive member is disposed concentrically about the tube-like shaft and at least partially along a longitudinal length of the tube-like shaft. The thermally conductive member is configured to increase a surface area of the tube-like shaft to dissipate thermal energy about the increased surface area. | 12-23-2010 |
| 20110092971 | Electrosurgical Pencil with Advanced ES Controls - An electrosurgical system is provided that includes an electrosurgical generator; and an electrosurgical pencil selectively connectable to the electrosurgical generator. The electrosurgical pencil includes an elongated housing; at least one electrocautery end effector removably supportable within the housing and extending distally from the housing, the electrocautery end effector being connected to the electrosurgical generator; and at least one voltage divider network supported on the housing. The at least one voltage divider network is electrically connected to the electrosurgical generator and controls at least one of the intensity of electrosurgical energy being delivered to the electrosurgical pencil and the mode of electrosurgical energy being delivered to the electrosurgical pencil. The voltage divider network generates a plurality of characteristic voltages which are measurable by the electrosurgical generator and which electrosurgical generator in turn transmits a corresponding waveform duty cycle at a particular intensity to the electrocautery end effector of the electrosurgical pencil. | 04-21-2011 |
