Abstract

An ultrasonic surgical instrument is provided. The ultrasonic surgical instrument includes a housing having an elongated shaft extending therefrom. The shaft defines a longitudinal axis therethrough and has at least one jaw member disposed at a distal end thereof. The jaw member(s) is movable between open and clamping configurations. A probe extends through the shaft and operably couples to the housing. The probe includes a cutting blade at a distal end thereof adjacent the jaw member(s) to treat tissue of interest. The jaw member(s) and cutting blade are configured such that heat damage to tissue adjacent tissue of interest that has been treated by the cutting blade is reduced and/or eliminated.
