An improved directed energy surgical method and assembly is disclosed. The method and assembly contemplate the application of a directed energy stream to tissue and the application of a liquid mist stream to the tissue to reduce or eliminate smoke at the surgical site. The invention may be advantageously implemented in an assembly having a surgical pencil (10) for emitting the directed energy stream and liquid mist stream. The liquid mist stream is generated by the surgical pencil (10), preferably by atomizing a liquid stream supplied thereto (e.g., pressurized via jet atomization). The invention may be utilized in connection with conventional electrosurgical, laser surgery, ultrasound, and other techniques and devices.

L'invention a pour objet l'amélioration d'un procédé et d'un ensemble chirurgical à énergie dirigée. Dans ce procédé et cet ensemble, on applique un courant d'énergie dirigée ainsi qu'un courant de brouillard liquide sur les tissus pour réduire ou supprimer la fumée sur le site chirurgical. L'invention peut être mise en oeuvre, de manière avantageuse, dans un ensemble comportant un crayon chirurgical (10) pour émettre le courant d'énergie dirigée et le courant de brouillard liquide. Le courant de brouillard liquide est généré par le crayon chirurgical (10), de préférence, par pulvérisation d'un courant liquide amené à ce dernier (par exemple, pulvérisation par jet). L'invention peut s'appliquer dans le domaine électrochirurgical traditionnel, dans la chirurgie par laser, par ultrasons, et dans d'autres techniques et dispositifs.
