Detailed Description

In order to make the present invention clearer, the present invention will be further described with reference to the accompanying drawings.

Fig. 1 illustrates an ultrasonic tool shank 1 according to some embodiments of the present invention, where the ultrasonic tool shank 1 may include a shank body 10 and a dynamic balancing device 20. The dynamic balance device 20 may include a ring body 21 integrally combined with the tool shank body 10 and a weight member 23 engaged with the ring body 21. In the ultrasonic scalpel handle 1, the ring body 21 is integrally coupled to the handle body 10, and thus the ultrasonic scalpel handle has at least the following advantages: (1) the structure is simpler; (2) in the processing process, the coaxiality and the dynamic balance between the ring body 21 and the tool handle body 10 are better; (3) compared with a sleeved non-integral ring body, the adverse effect of the processing precision and the assembling precision of the inner ring of the ring body on the dynamic balance can be eliminated.

In some embodiments, the tool shank body 10 may be cylindrical and the ring 21 may be annular. The ring body 21 is coaxially coupled to the shank body 10 by means of integral molding. The ring body 21 includes a flat upper wall surface 211, a lower wall surface 212 parallel to the upper wall surface 211, and a cylindrical outer wall surface 213 interposed between the upper wall surface 211 and the lower wall surface 212, the outer wall surface 213 being formed with a plurality of weight ports 210 in a circumferential direction, the weight ports 210 being cylindrical and uniformly distributed in the circumferential direction of the outer wall surface 213 in a radial direction of the ring body 21. These weight ports 210 are used to mount the weight 23 to enable adjustment of the center of gravity.

The weight member 23 may be cylindrical in some embodiments, and the outer wall surface is formed with external threads. Correspondingly, the weight port 210 is also cylindrical and has an internal thread on its inner wall for mating with the external thread of the weight member 23. The weight member 23 also has an operation hole 230 formed on an outer end surface thereof to facilitate tool driving of the weight member 23. And in some embodiments may be a jackscrew.

Fig. 2 shows an ultrasonic tool shank 1a according to other embodiments of the present invention, where the ultrasonic tool shank 1a may include a shank body 10a and a dynamic balancing device 20 a. The dynamic balancing unit 20a may include a ring body 21a integrally coupled to the tool shank body 10a, and a first weight member 23a and a second weight member (not shown) having a smaller diameter that are coupled to the ring body 21 a. In the ultrasonic blade holder 1a, since the ring body 21a is integrally coupled to the blade body 10a, at least the following advantages are obtained: (1) the structure is simpler; (2) in the machining process, the coaxiality and the dynamic balance between the ring body 21a and the tool shank body 10a are better; (3) compared with a sleeved non-integral ring body, the adverse effect of the processing precision and the assembling precision of the inner ring of the ring body on the dynamic balance can be eliminated.

In some embodiments, the tool shank body 10a may be cylindrical and the ring 21a may be annular. The ring body 21a is coaxially coupled to the shank body 10a by means of integral molding. The ring body 21a includes a flat upper wall surface 211a, a lower wall surface 212a parallel to the upper wall surface 211a, and a cylindrical outer wall surface 213a interposed between the upper wall surface 211a and the lower wall surface 212a, the outer wall surface 213a is formed with a plurality of first weight ports 210a and a plurality of second weight ports 214a having a smaller diameter in a circumferential direction, the weight ports are cylindrical, and are uniformly distributed in a circumferential direction of the outer wall surface 213a in a radial direction of the ring body 21 a.
