Abstract

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.
