Multifunction electrocautery tool
First Claim
1. A multifunction electrocautery tool comprising:
- an elongated housing;
an elongated suction tube slidably supported within said housing and defining a suction passage therethrough;
a slide control coupled to said suction tube and movably supported upon said housing, said slide control defining a control aperture and a control passage coupling said aperture to said interior passage of said suction tube; and
an electrocautery blade supported upon said housing,said slide control being operable to move said suction tube within said housing and said control aperture being used to alter the suction characteristic of said suction tube, whereby said multifunction electrocautery tool provides combined control of the deployment of suction, tube retraction and aspiration control in a common unit operable in one hand.

Abstract
A multifunction electrocautery tool includes an elongated housing within which a generally cylindrical suction tube is slidably supported. A slide control is mechanically coupled to the suction tube and movable to control the retraction and extension thereof. The slide control includes an aperture coupled to the suction passage of the suction tube to facilitate a single finger or thumb control of the suction tube position and suctioning action. A cauterizing and cutting blade is supported proximate the suction tube and is coupled to a source of RF electrical energy by a connecting wire. In one embodiment, electrical controls for the cauterizing blade are supported upon the upper surface of the elongated housing while a pair of oppositely positioned slide controls are provided on right hand and left hand side surfaces to facilitate either right or left hand operation. In an alternate embodiment, a slide control is supported upon the upper surface which includes a control aperture coupled to the suction passage of the suction tube.
