摘要：
An ultrasonic device may include an ultrasonic system including a transducer coupled to an ultrasonic blade, A method of delivering energy to the device may include sensing a vessel contacting the blade, identifying that the vessel is calcified, and generating a warning. In some aspects, the method further includes disabling one or more activation functions of the blade. In another aspect, the method further includes generating a message to apply compression to the vessel for a predetermined period, disabling activation functions of the blade during compression, and enabling activation functions after the expiration of the compression period. In yet another aspect, the method includes applying a compressive clamp force to the calcified vessel by driving a clamp arm toward the blade, disabling activation functions of the blade during compression, and enabling the activation functions after adjusting the compressive force. An ultrasonic surgical instrument may effect the method.
