Patent number: 8128622Abstract: The present disclosure is directed to electrosurgical pencils having variable controls. In one aspect, the electrosurgical pencil, includes an elongated housing, an electrocautery blade supported within the housing and extending distally from the housing, the electrocautery blade being connected to a source of electrosurgical energy, an activation button supported on the housing, the activation button being movable from a first position to at least a subsequent position, and a transducer electrically connected between the activation button and the source of electrosurgical energy. The transducer is configured to transmit an electrical output signal to the electrosurgical energy source correlating to the movement of the activation button. The source of electrosurgical energy correspondingly supplies an amount of electrosurgical energy to the electrocautery blade dependant upon the electrical output signal.Type: GrantFiled: July 9, 2007Date of Patent: March 6, 2012Assignee: Covidien AGInventors: Ronald J Podhajsky, Dale Francis Schmaltz, Arlan James Reschke

Patent number: 7033353Abstract: A nozzle and electrode combination for use with an electrosurgical device is described. The nozzle includes a shroud defining a channel and a lumen which intersect to define an acute angle. An electrode is positioned within the channel and includes a distal end extending from a distal portion of the shroud and a proximal end extending from the proximal portion of the shroud. An end cap positioned adjacent the proximal portion of the shroud about the electrode is preferably overmolded to the shroud and the electrode. Preferably, a portion of the walls defining the channel and/or the lumen include conductive material which communicates with the electrode to eliminate electric potential within the shroud.Type: GrantFiled: July 28, 2003Date of Patent: April 25, 2006Assignee: Sherwood Services AGInventors: Robert Bryant Stoddard, Cliff Rodes Ketcham, Arlan James Reschke
