Abstract: A tool assembly for use with an electrosurgical device for cutting tissue includes a base portion, a return lead, an electrical insulator, a center pin, and an active lead. The center pin extends from the base portion and through a lumen of the electrical insulator. The active lead is securely fixed to the base portion and extends between the base portion and a distal portion of the center pin such that a portion of the active lead extends around the distal portion of the center pin and first and second segments of the active lead are spaced apart from the return lead. Upon activation, electrosurgical energy is transmitted from the active lead through tissue to the return lead to cut tissue in contact with the active lead.

Abstract: A hose guide arranged for permitting reorientation and guidance of a fluid in a pneumatic hose is provided to include a central support post mounting an abutment disc at its upper end, and rotatably mounting roller guide discs below the abutment guide disc to permit orientation and alignment of hoses along the guide discs relative to and below the abutment disc.
