Abstract
A cautery device includes an elongated handpiece extending axially from a proximal end to a distal end and a cautery tip extending coaxially with the handpiece from the distal end of the handpiece. The tip defines a channel extending coaxially with the handpiece along at least a portion of the length of the cautery tip from a proximal open end to a distal end. The device includes a gas supply connection extending from the proximal end of the handpiece for supplying gas to the cautery tip. The gas supply connection is fluidly coupled to the cautery tip. The device includes an electric supply connection extending from the proximal end of the handpiece for supplying electricity to the cautery tip. The electric supply connection is electrically coupled to the cautery tip. The gas supplied to the cautery tip is introduced to the channel at the proximal open end and exits to envelop the distal tip.
