摘要： An ultrasonic surgical clamp coagulator apparatus is configured to effect cutting, coagulation, and clamping of tissue by cooperation of a clamping mechanism of the apparatus with an associated ultrasonic end-effector. Selective, indexed rotational positioning of the clamping mechanism and end-effector is achieved by the provision of a detent mechanism incorporated into the clamp drive mechanism of the apparatus. The arrangement permits an elongated portion of the apparatus to be selectively rotatably positioned with respect to an apparatus housing, with an associated ultrasonic drive unit operatively coupled to a waveguide of the apparatus for rotation together with the clamping mechanism. The detent mechanism desirably resists relative rotation of the apparatus unless a predetermined torque is applied thereto, thus facilitating efficient and convenient use during surgical procedures.
