ABSTRACT:
A bipolar suction tonsillar dissector is provided which is especially useful in tonsillectomies and adenotonsillectomies to minimize hemorrhage and tissue damage by promoting surgical efficiencies. The instrument hereof includes a pair of arms connected by a connector plug to define a forceps. One arm includes a tubular suction channel which may be connected to a source of vacuum and presents an opening at the remote end through which undesired or excess fluid may be removed from the dissection site. The other arm includes a dissecting blade for enabling the surgeon to remove or cut away tissue. Advantageously, the blade and structure adjacent the opening define electrodes whereby the surgeon may, without delay in switching instruments, electrocoagulate hemorrhaging blood vessels and then return to dissection and suction of the blood or other fluid.
