Ultrasonic soft tissue cutting and coagulation systems having a curvilinear blade member and clamp

摘要

Ultrasonic soft tissue cutting or coagulating systems are disclosed that include an ultrasonic blade member for cutting and/or coagulating tissue, and an opposed clamp member which is used together with the blade member to compress/clamp the tissue being treated. At least one of the blade member and the clamp member has a substantially curvilinear configuration. The ultrasonic blade member and the opposing clamp member can have substantially curvilinear and dissimilar configurations which enables soft tissue to be treated evenly across the contact surface
