Abstract
Provided is an ultrasonic surgical knife blade. The projection of the blade on a shear plane is banana-like curved shape. From a proximal end to a distal end, the thickness of the blade varies from thick to thin, and then to thick and to thin again. The projection on a vertical shear plane is fruit knife-shaped. The height of the blade varies from high to low, and then gradually decreases, and an arc-shaped cutting groove is formed in the middle position. The present invention allows for an increase of swing amplitude in the bending direction and the effective working length of the blade. A boat-shaped or arc-shaped balance cutting groove is provided between the most distant node and a tip of the blade, such that the stability of ultrasonic vibration is improved.
