Abstract
A smoke aspirating electrosurgical device includes an electrically conductive blade attached to an axial end of a device handle. The handle is constructed to form an interior channel extending from the blade end of the handle to the opposite end for aspiration of smoke produced by electrosurgical incisions with the blade. The interior channel can be connected to a vacuum source through a tube extending from the channel.
Claims6
An electrosurgical device for incising anatomical structures and evacuating smoke produced thereby, said device comprising:
- an electrically conductive blade for incising said anatomical structures;
- an elongated handle for holding and manipulating said blade, said handle having a first axial end to which said blade is connected;
- an electric connecting means for electrically connecting said blade to an electric power source;
- electric control means positioned along a top of the handle for switching electric power to said blade;
- and
- aspirating means for permitting passage of said smoke through said handle, wherein said aspirating means includes an interior channel formed by said handle, said channel extending from a channel inlet at said first axial end to a channel outlet at a second axial end of said handle opposite said first end and wherein said channel inlet is separated from and disposed above said blade along a top side of said blade, said inlet thereby capturing smoke rising from said blade.
