Wire electrode devices for tonsillectomy and adenoidectomy

摘要

Monopolar electrosurgery devices adapted for resecting tonsil and adenoid tissue. The devices minimize thermal injury by employing a plasma generated by pulsed electrical signals to precisely and effectively cut or coagulate the tissues. Suction may also be applied to the tissues to enhance the cutting, coagulation, and tissue manipulation functions. The devices include an interchangeable tip that may be switched for another tip, depending on which tip may be more suitable for tonsillectomy or adenoidectomy.

主权项

1. An electrosurgical device comprising:
a) an elongate body having a proximal end, a distal end, and defining a lumen for applying aspiration extending therethrough; b) a tip having a proximal end, a distal end, and defining a tip lumen fluidly connected to the aspiration lumen at the distal end of the elongate body; c) a housing secured to the distal end of the tip and defining an aperture fluidly connected to the tip lumen; and d) an electrode assembly in the housing and comprising an active electrode, wherein the electrode assembly or a portion thereof defines an aspiration port communicating with the aperture in the housing.
