Electrosurgical device

An electrocautery pencil, comprising:

• a body;
• a non-movable monopolar electrocautery electrode fixedly secured to the body, the non-moveable monopolar electrocautery electrode including a distal tip;
• a heat shroud defining an internal lumen and a distal end, the heat shroud being translatable relative to the non-moveable monopolar electrocautery electrode between a first position wherein the distal tip of the non-movable monopolar electrocautery electrode is disposed entirely within the internal lumen and proximal to the distal end of the heat shroud, and a second position wherein the distal tip of the non-moveable monopolar electrocautery electrode is disposed distal to the distal end of the heat shroud, and wherein the heat shroud is constructed of a heat-resistant material configured to shield the distal tip of the non-movable monopolar electrocautery electrode when in the first position;
• a first electromagnet which is operably connected to the body;
• a second electromagnet which is operably connected to the body;
• a permanent magnet disposed between the first and second electromagnets and operably connected to the heat shroud;
• wherein the first electromagnet and the permanent magnet magnetically interact to releasably maintain the heat shroud in the first position;
• wherein the second electromagnet and the permanent magnet magnetically interact to releasably maintain the heat shroud in the second position;
• wherein the permanent magnet is configured to shift between the first electromagnet and the second electromagnet in response to an electrical current being applied to the first electromagnet, the second electromagnet or both the first electromagnet and the second electromagnet;
• wherein the first electromagnet is free of the electrical current when the permanent magnet and the first electromagnet magnetically interact to releasably maintain the heat shroud in the first position;
• wherein the second electromagnet is free of the electrical current when the permanent magnet and the second electromagnet magnetically interact to releasably maintain the heat shroud in the second position;
• and
• a multi-function control actuator coupled to the body, wherein actuating the multi-function control actuator to a first configuration translates the heat shroud from the first position to the second position, wherein actuating the multi-function control actuator to a second configuration energizes the non-movable monopolar electrocautery electrode, and wherein releasing the multi-function control actuator translates the heat shroud from the second position to the first position.
