The transducer coil 140 according to an embodiment of the present invention is formed into a cylindrical annular shape having an inner circumferential surface of a predetermined diameter and an outer circumferential surface of a predetermined diameter. The transducer coil 140 is positioned within the housing to generate a magnetic field.

The transducer coil contact means 130 according to an embodiment of the present invention is configured to increase the strength with which the transducer coil 140 is brought into close contact with a part of the housing. That is, the transducer coil contact means 130 may be configured to closely contact and fix the transducer coil 140 to a part of the outer case 110. In other words, the transducer coil contact means 130 may be configured to increase the strength with which the transducer coil 140 is brought into close contact with a portion of the outer case 110.

For example, the surface of the transducer coil 140 may be epoxy coated. The transducer coil 140 may be positioned within the outer case 110 to generate a magnetic field.

In addition, the transducer coil 140 according to an embodiment of the present invention may include one or more coupling portions on the inner circumferential surface of the transducer coil 140. More specifically, the inner circumferential surface of the transducer coil 140 may include one or more projections to engage with the transducer coil contact means 130. The protrusion may be, for example, a protrusion formed with a predetermined diameter and / or height. Such protrusions may be formed, for example, through an epoxy coating. The protruding portion formed on the inner circumferential surface of the transducer coil 140 may not allow the transducer coil contact means 130 to escape to the outside. Alternatively, the transducer coil 140 may include one or more grooves on the inner circumferential surface of the transducer coil 140 to engage the transducer coil contact means 130. In addition, a combination of one or more protrusions and one or more grooves may be formed in the inner circumferential surface of the transducer coil 140. Reference is made to the transducer coil 130 shown in Figs. 2 to 3 in this connection.

4, the transducer coil contact unit 130 is coupled to the outer circumference of the transducer coil 140 by the coupling unit formed on the inner circumferential surface of the transducer coil 140, (110).

In addition, the transducer coil contact means 130 according to an embodiment of the present invention may be formed to correspond to at least one of the diameter and the height of the inner circumferential surface of the transducer coil 140. Any portion of the transducer coil contact means 130 may be formed, for example, to have the same circumference as the circumference of the inner circumferential surface of the transducer coil 140, but not necessarily, and may have various peripheries as needed .

The transducer coil contact means 130 is coupled to the inner circumferential surface of the transducer coil 140 so that the transducer coil 140 is tightly fixed to the outer case 110 (see FIG. 7). The position of the transducer coil 140 can be constant for each medical device 100 by fastening and fixing the transducer coil 140 in the outer case 110. [ Thereby, the performance difference between the medical devices 100 can be reduced. 5 to 7 will be described later in more detail.

According to an embodiment of the present invention, the transducer coil contact means 130 may be formed of at least one material selected from among acrylonitrile butadiene styrene copolymer (ABS) and polycarbonate (PC). In addition, the transducer coil contact means 130 may be made of, for example, polyvinyl chloride (PVC), polyurethane (PU), nitrile-butadiene rubber (NBR), hydrogenated nitrile rubber (HNBR), styrene butadiene rubber and may be formed of at least one of polychloroprene rubber, isoprene-isobutylene rubber (IIR), butadiene rubber (BR), isoprene rubber (IR), ethylene propylene rubber (EPR) The material of the above-described transducer coil contact means 130 is illustrative, and the present invention is not limited thereto.

Hereinafter, the effects of the transducer coil contact means will be described below with reference to Figs. 5 to 7. Fig.

Figure 5 illustrates a side view of a transducer coil and transducer in accordance with one embodiment of the present invention.

Figure 6 shows a perspective view of a transducer coil and transducer in accordance with an embodiment of the invention.

Figure 7 shows a perspective view of a transducer coil and transducer coil tightening means combined in accordance with an embodiment of the present invention.

Referring to FIG. 5, the transducer coil 140 may include a protrusion on the inner circumferential surface thereof. The transducer coil contact means 130 can be coupled to the transducer coil 140 without being released to the outside by the projection located on the inner circumferential surface of the transducer coil 140 and the transducer coil 140 can be coupled to the outer case 110 Tightly fixed. That is, the transducer coil 140 and the transducer coil contact means 130 are coupled in an insertion manner to allow the transducer coil 140 to be closely fixed to the outer case 110. Alternatively, the transducer coil 140 and the transducer coil contact means 130 may be coupled together in a screwed manner. The above described fitting method is merely an exemplary method for coupling the transducer coil 140 and the transducer coil contact means 130 according to an embodiment of the present invention, and the present invention is not limited thereto.

Although not shown, the conventional medical device 100 includes fixing means of elastic material on the upper and lower sides of the transducer coil 140, respectively, for fixing the transducer coil 140 in the outer case 110 . The fixing means is located on the upper side and the lower side of the transducer coil 140. The fixing means located on the upper side of the transducer coil 140 applies pressure in the downward direction and the fixing means located on the lower side of the transducer coil 140 in the upward direction, (140).

In this case, the upper side and the lower side of the transducer coil 140 where the magnetic field is generated are enclosed by the fixing means, and furthermore, the outer side of the transducer coil 140, There is a disadvantage that the distance between the affected part and the magnetic field generating position is long. In addition, there is a disadvantage that the medical device 100 becomes excessively thick. Further, when the electric current is abrupt, there is a noise generated when the transducer coil 140 collides with the fixing means. Further, when the transducer coil 140 is fixed in the outer case in a conventional manner, the performance difference between the transducer coil 140 and the transducer coil 140 varies depending on the position of the transducer coil 140 in the fixing means.

According to an embodiment of the present invention, the transducer coil 140 may be closely fitted to the outer case 110 by being coupled with the transducer coil contact means 130 inside the transducer coil 140. That is, there is no fixing means for fixing the transducer coil 140 to the outer case 110 at the upper side and the lower side of the transducer coil 140, but the transducer coil 140 is provided inside the transducer coil 140 The transducer coil 140 can be fixed to the outer case 110 by being coupled with the means 130.

Therefore, according to the embodiment of the present invention, since the thickness is not further increased by the means for fixing the transducer coil 110, the distance between the lesion and the magnetic field generating position can be shortened. That is, the efficiency of the medical device 110 can be increased because the magnetic field energy of the same magnitude generated by the transducer coil 110 is closer to the affected part. Additionally, the medical device 100 also has the advantage of being thinner and lighter.

Furthermore, even when the electric current is abrupt, the vibration noise can be reduced since the transducer coil 140 does not collide with the fixing means existing above and below the transducer coil, as in the conventional case.

In some cases, the performance difference is different depending on the position where the transducer coil 140 is present in the outer case 110 by the transducer coil contact means 130.

The effects according to one embodiment of the present invention are not limited to those described above.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. will be.
