Abstract: A laser and electrosurgical system (10) has a handpiece (12) with a proximal and distal end (13) and (14) from which laser radiation (17) and/or electrosurgical energy (18) is selectively or concurrently directed. The ends are along an axis; an electrode extends distally along the axis. Sources of laser and electrosurgical energy (18) are available and controlled. An initiation circuit (25) for the laser selectively delivers it before electrosurgery. Prior delivery to target tissue, the laser creates an ionized conductive pathway for electrosurgery. The combined concurrent application of laser and electrosurgery has a mechanism (27) to selectively distribute energy about the axis. A laser deflecting surface (28) or a beam deflector vibrate relative to the axis. A power switch (30) has levels for laser cut and ionization and/or a delay therebetween for electrosurgical coagulation. A wave guide (34) or an array thereof deliver radiation along the axis. A method has steps of directing selectively and concurrently laser and electrosurgery by aiming the axis, controlling laser and electrosurgical energy (18), delivering laser before electrosurgery, forming an ionized conductive pathway for the electrosurgery, distributing the laser about the axis in a predetermined pattern by deflecting the laser in a predetermined pattern generally along but slightly displaced from the axis to direct electrosurgical energy (18) in a predefined pattern on the patient's (11) target tissue. In another possible approach, there are additional steps of delivering the laser radition (17) as a beam and varying an ionized conductive pathway by refracting or diffracting the laser radiation (17) beam with the mechanism (27) having a beam pattern deflector.

Abstract: Un sistema láser y electroquirurgico 10 tiene un mango 12 con unos extremos proximo y lejano 13 y 14, desde el cual se dirige radiacion láser 17 y/o energía electroquirurgica 18 de forma selectiva o concurrente. Los extremos están situados a lo largo de un eje; un electrodo se extiende en direccion lejana a lo largo del eje. Fuentes de energía láser y electroquirurgica 18 están disponibles y son controladas. Un circuito iniciador 25 del láser lo proporciona de forma selectiva antes de la electrocirugía. El suministro anterior es dirigido hacia el tejido. El láser crea un trayecto conductor ionizado para la electrocirugía. La aplicacion concurrente combinada de láser y electrocirugía tiene un mecanismo 27 para distribuir energía alrededor del eje de forma selectiva. Una superficie deflectora 28 de láser o un deflector de haces vibra con respecto al eje. Un conmutador de potencia 30 tiene niveles para practicar incisiones con láser y producir la ionizacion, y/o un retardo entre los mismos para la coagulacion electroquirurgica. Una guía de ondas 34 o un conjunto de las mismas dirige radiacion a lo largo del eje. Un procedimiento tiene etapas consistentes en dirigir láser y electrocirugía de forma selectiva y concurrente apuntando a lo largo del eje, controlar energía láser y electroquirurgica 18, suministrar láser antes de la electrocirugía, formar un trayecto conductor ionizado para la electrocirugía, distribuir el láser alrededor del eje segun una característica predeterminada desviando el láser segun una característica predeterminada, generalmente a lo largo del eje, pero ligeramente desplazado del mismo, para dirigir energía electroquirurgica 18 segun una característica predefinida hacia el tejido diana del paciente 11. En otro posible concepto, existen etapas adicionales consistentes en suministrar la radiacion láser 17 en forma de haz y variar un trayecto conductor ionizado refractando o difractando el haz láser 17 mediante el mecanismo 27 que tiene un deflector de la característica direccional del haz.
