The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and are not limiting of the invention. It should be noted that, for convenience of description, only the relevant portions of the related inventions are shown in the drawings.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

Fig. 1(a) shows a schematic structural view of one embodiment of the ultrasonic surgical blade holder of the present application. As shown in fig. 1(a), the ultrasonic surgical knife bar 100 includes an ultrasonic energy output end 101 and an ultrasonic energy conducting rod 102, wherein the ultrasonic energy output end 101 is disposed on the ultrasonic energy conducting rod 102, and the ultrasonic energy output end 101 is provided with longitudinal texture.

Specifically, the longitudinal texture may be a texture extending in the axial direction of the ultrasonic energy output port 101 (in the direction indicated by the arrow in fig. 1 (a)), and the longitudinal texture may be formed by various means. For example, the ultrasonic surgical blade holder is processed to form a texture using a tool such as a lathe, a milling cutter, a grinding wheel, a leather wheel, or a saw blade. As shown in cross-section a-a in fig. 1(b), the edge serrations are formed by the longitudinal grain. Because when using ultrasonic operation cutter arbor to carry out the operation, the horizontal cross-section of cutter arbor (the plane perpendicular with the pivot of cutter arbor promptly) need bear certain dynamics, sets up vertical texture on ultrasonic energy output end 101, can increase the intensity of cutter arbor when carrying out the operation, reduces the cracked possibility of cutter arbor.
