The inclination adjustment may be performed by the adjustment unit 12 including the connection case 121 formed at the end portion of the operation housing 11 and the adjustment handle 122 formed in the connection case 121. [

An embodiment of the cutting clip 15 and the adjustment unit 12 will be described again below.

2A and 2B illustrate an embodiment of a cutting unit applied to an ultrasonic applicator according to the present invention.

Referring to FIG. 2A, the cutting unit includes a cutting tip 22, and the cutting tip 22 includes a connecting member 221 having a circular cross section extending from a transmitting member 21 to which ultrasonic waves are transmitted; And a contact member 222 that extends from the connecting member 221 and has a polygonal cross section and extends linearly and a lower portion 223 of the contact member 222 extends in a small cross sectional area as compared with the upper portion .

Ultrasonic waves generated in the transducer can be transmitted through the transmitting member 21 and transmitted to the cutting tip 22, and the cutting tip 22 can be linear, curved, have. The cutting member 21 or the cutting tip 22 may be any material capable of transmitting ultrasonic waves, and may be made of a metal, an alloy, or a synthetic resin and a material. The material of the cutting member 21 or the cutting tip 22 is not particularly limited since substantially ultrasonic waves are transmitted through solid, liquid and gas. The transmitting member 21 can be made of a material preferably having a circular cross section, whereby ultrasonic waves generated in the transducer can be transmitted without loss. On the other hand, it is advantageous that the cutting tip 22 has a structure capable of easily transferring the ultrasonic wave to the cutting portion, and is preferably made of a material having different medium characteristics as compared with the cutting portion. For this purpose, the cutting tip 22 may have a planar shape in a direction perpendicular to the extending direction, and a length in a direction in which the horizontal direction is perpendicular to the length in the direction perpendicular to the extending direction It can be big. In addition, the tip of the cutting tip 22 may be coated with a medium capable of reflecting the transmitted ultrasonic waves. With such a structure, the structure of the cutting tip 22 may be such that the lower portion 223 extends with a small cross section as compared with the upper portion. Specifically, the cutting tip 22 may be composed of a connecting member 221 having a smaller cross section than the transmitting member 21 and a contacting member 222 extending from the connecting member 221. The connecting member 221 may be integrally formed with the contact member 222 and may be formed by cutting both sides of the connecting member 221 into a planar shape. The lower portion 223 can be made by cutting the lower side of both sides to be inwardly inclined after the side faces are cut again. Accordingly, the upper rectangular portion and the lower triangular portion of the cross section of the contact member 221 may be connected. The cutting tip 22 can be made in various configurations and the invention is not limited to the embodiments shown.

The contact member 222 may be fixed to the cutting groove 232 formed in the tip fixing base 23 in the cutting process. The fixed base (23) has a base plate (231) having an upper portion in a planar shape; A cutting groove (232) formed into a shape in which at least a part of the contact member (221) is received while bisecting the base plate (231) in the longitudinal direction; And a movement restricting projection 233 formed on the upper plane of the base plate 231. [ Further, a coupling blade 234 coupled to the cover base 24 may be formed on one side of the tip fixing base 23. In addition, a separating strip may be formed below the cut groove 232 to prevent the contact member 222 from contacting the side or bottom surface of the cut groove 232. A plurality of separation strips are disposed in a direction perpendicular to the longitudinal direction of the cut groove 232 to prevent the ultrasonic waves from being dispersed through the cut groove 232. The movement restricting protrusion 233 may be formed to have a relatively large height as compared with the base plate 231 as compared with a side portion where one side portion faces each polygonal cross section for fixing the cutting peripheral portion . The movement restricting protrusions 233 may be formed in such a manner that a band inclined with respect to the longitudinal direction of the cut groove 232 is arranged and each of the movement restricting protrusions 233 may be separately arranged at regular intervals.

The lid base 24 can be coupled to the lower side of the tip fixing base 23 and includes a receiving plate 241 and a fixing groove 242 formed in the receiving plate 241 to receive the lower portion of the cutting groove 232, And a rotation fixing unit 243 to which the coupling wing 234 is coupled. An axis projection 243a is formed in the rotation fixing unit 243 so that the fixing base 23 is separated from and contacted with the cutting unit according to the operation of the handle described above.

2B shows a process in which ultrasonic waves are transmitted to the cutting tip 22 for cutting and FIG. 2B shows the cutting tip 22 before or after cutting from the tip fixing base 23 And shows the separated state.

The ultrasonic waves are transmitted to the cutting tip 22 through the transmitting member 21 and can be converted into heat while being transmitted to the cutting site. The divergence of heat can be reduced by fixing the tip fixing base 23 to the cover base 24. The tip fixing base 23 and the cover base 24 before and after cutting can be kept separated from the cutting tip 22 by the rotation fixing unit 243. By operating the handle as described above, the cutting tip 22 and the tip fixing base 23 are brought into contact with each other while the fixed base is rotated with respect to the rotation fixing unit 243, and the ultrasonic waves are transmitted through the transmitting member 21 So that cutting can be performed.

The cutting tip 22 and the tip fixing member 23 can be operated in various ways, and the present invention is not limited to the embodiments shown.

In the ultrasonic applicator according to the present invention, the cutting clip can be inclined with respect to the transmitting member, and the inclination can be adjusted with the inclination adjusting unit.

And the inclination adjusting unit can be fixed to the connection case by the insertion pin (35).

The moving block 31 is composed of a body 311 having a sliding inner surface 313 and a fixing hole 312 formed therein and the side wing 322 of the adjusting block 32 is fixed to the body 311 through the fixing holes 312 As shown in Fig. The moving protrusion 323 may be formed on the body plate 321 of the adjusting block 32 and the moving protrusion 323 may be moved along the inclined groove 342 formed in the induction body 341 of the induction plate 34 . The guide plate 34 can be coupled to the lower side of the engaging block 33 and the moving protrusion 323 can be moved along the inclined groove 342. [ The engaging block 33 includes an engaging body 331 formed with an engaging groove 333 to which the engaging protrusion 122a formed on the upper plane is engaged. A side wing 334 coupled to the side surface of the adjustment block 32 while fixing the guide plate 34; And a corresponding groove 335 corresponding to the inclined groove 342 may be formed on the rear surface of the coupling body 331. [ The insertion pin 35 may include a rotation inducing portion 351 connected to the adjustment handle 122 and a fixing portion 352 fixed to the connection case.

The connecting member 37 can connect the slope adjusting unit and the cutting clip to each other and one end of the connecting member 37 can be fixed to the lower surface of the moving block 31 having a semi-cylindrical shape. The one end may be fixed to one side of the moving block 31 so that it is deflected and the extension hole 372 may be formed and fixed to form a moving margin. And a fastening hole 371 may be formed at the other end of the connecting member 37. The fastening hole 371 may be coupled to the fastening hole 39 formed on one side of the rotation fixing unit 243 formed in FIG. 3C.
