Abstract

An electro surgical instrument comprising a handle and a replaceable blade. The handle includes a blade receiving slot and means for clamping the proximal portion of the blade within the slot. Also formed internally of the handle and within the slot is a cavity for containing an electrical-to-mechanical transducer and a plurality of conductive terminal pad areas. The blade is provided with a pattern of conductors which are insulated from one another and which lead to contact pad areas on the distal portion of the blade. When the blade is appropriately inserted into the handle and clamped in place, the transducer abuts the blade and electrical contact is established to energize the conductors and the transducer whereby the blade may be vibrated at a frequency and amplitude to limit the build-up of tissue debris on the blade during an electro surgery procedure.
