Ultrasonic Scaler Driver generates ultrasonic wave by generating mechanical vibration from power supply pressure by using piezoelectric phenomenon that converts electric energy into mechanical energy and removes dental plaque from tooth, .
1, the conventional ultrasonic scaler 10 has a tip 110 coupled to a distal end thereof. The tip 11 is formed to have a maximum ultrasound vibration efficiency at its distal end as shown in FIG. 2 It is curved.
The tip 11 is typically made of iron, copper, titanium, and metal alloys, and wear occurs when the tip 110 is repeatedly used.
The performance of the tip 11 is closely related to the wear rate, and it is generally known that when the tip of the tip 11 is worn at 1 mm, the performance is reduced by 25%, and when the tip is reduced by 2 mm, the performance is reduced by 50% . It is therefore recommended to set the abrasion limit of the tip 11 to 2 mm normally and replace it when the tip 11 reaches the abrasion limit.
However, in the conventional scaler tip 11, all the parts including the distal end are made of the same material, and a special label is not formed. Thus, in order to identify to what extent the wear has progressed, (20) was used.
A tip groove 21 is formed in the identification card 20, and a reference line 22 indicating a wear limit point is marked. The user inserts the tip 11 into the tip groove 21 of the identification card 20 and confirms that the tip 11 is worn more than the reference line 22.
However, since it is very cumbersome for the user to check the abrasion state of the tip 11 every time using the identification card 20 in the process of using the ultrasonic scaler, the abrasion state is not confirmed through the identification card 20 in the field, In many cases, the timing of replacement was judged by the sense.

Hereinafter, a tip for an ultrasonic scaler according to the present invention and a method of manufacturing the same will be described in detail with reference to the accompanying drawings.
FIG. 4 shows a first embodiment of a tip 100 for an ultrasonic scaler according to the present invention.
As shown, the ultrasonic scaler tip 100 includes a body 110 that can be mounted to an ultrasonic scaler, and an actuating portion 120 formed at the end of the body 110.
The actuating part 120 is formed so that the width thereof decreases as it extends toward the end so that foreign matter can be removed by contacting the surface to be scaled. The boundary of the main body 110 is referred to as a wear limit line.
If the abrasion progresses until the actuating part 120 reaches the abrasion limit line, the scaling performance is remarkably deteriorated. Therefore, the replacement should be performed, so that it is discriminated whether the operation part 120 is worn until it reaches the abrasion limit line The operation part 120 and the main body 110 may be coated with different colors so as to be distinguished by a difference in color.
The tip 100 for ultrasonic scaler according to the present embodiment includes a first coating layer 130 coated on the entire body 110 and the actuating part 120 and a second coating layer 130 coated on the upper layer of the first coating layer 130 excluding the actuating part 120. [ The second coating layer 140 is formed.
In this embodiment, titanium nitride (TiN) is applied to the first coating layer 130 and zirconium nitride (ZrN) is applied to the second coating layer 140. Titanium nitride has a dark gold color and zirconium nitride has a white gold color. Therefore, the coating layers of titanium nitride and zirconium nitride are easy to distinguish from each other.
Since the entire body 110 and the operation part 120 are first formed as the first coating layer 130 and the second coating layer 140 is coated on the remaining area except the operation part 120, Are colored in white gold by the second coating layer 140 and the operation part 120 in which the first coating layer 130 is exposed to the outside are colored in a dark gold color so that they can be clearly distinguished from each other.
Of course, unlike the present embodiment, the first coating layer 130 may be coated with zirconium nitride, and the second coating layer 140 may be coated with titanium nitride.
The first coating layer 130 and the second coating layer 140 may be formed of titanium nitride and zirconium nitride as well as titanium carbonitride (TiCN), titanium aluminum nitride (TiAIN) Chromium nitride (CrN), and titanium dioxide (TiO 2 ) may be formed by selecting two or more kinds of coating materials having mutually different colors.
5 and 6 show an apparatus and a manufacturing method for manufacturing the ultrasonic scaling tip of the first embodiment.
The manufacturing apparatus 300 for manufacturing the ultrasonic scaler tip 100 includes a jig 310 for fixing the main body 110 and an operation unit 120 installed to be able to move up and down from the jig 310, A coating chamber 320 for keeping the working area in a vacuum state during the coating operation, a first injection nozzle 340 and a second injection nozzle 350 for spraying the coating material, .
At the lower end of the main body 110, screw grooves are formed so as to be mounted on the ultrasonic scaler. The jig 310 may include a threaded fastening protrusion 311 corresponding to the threaded groove of the main body 110 so that the threaded groove can be used. .
At this time, it is preferable that the actuating part 120 is mounted so as to face upward so as to facilitate mounting of the first cap, and therefore, it is preferable that the fastening protrusion 311 is extended at a predetermined angle with respect to the supporting surface .
After the main body 110 is mounted on the jig 310, the chamber 320 is closed to make the internal space in which the coating operation is performed in a vacuum state, and then the coating material is sprayed onto the first injection nozzle 340).
After the first coating layer 130 is formed, the first cap mounting portion 330 is lowered and the first cap is mounted to cover the operation portion 120.
In this state, when the operation part 120 is covered with the first cap, the second coating material is sprayed through the second injection nozzle 350 to form the second coating layer 140 on the outer circumferential surface of the main body 110 not covered with the first cap .
The tip 100 for the ultrasonic scaler having the first coating layer 130 and the second coating layer 140 formed after the chamber 320 is opened and the first cap mounting part 330 is lifted and separated from the operation part 120, Is separated from the jig 310 and the work is finished.
5, only one of the first injection nozzle 340 and the second injection nozzle 350 is displayed. However, the first spray nozzle 340 and the second spray nozzle 350 are provided for the purpose of understanding the constitution, A plurality of first injection nozzles 340 and a plurality of second injection nozzles 350 may be installed in the chamber 320 so that the injection can be performed evenly and the first and second injection nozzles 340, (350) may be rotatably driven.
The tip 100 of the ultrasonic scaler according to the present invention manufactured through the above process can be clearly distinguished from the main body 110 by the first coating layer 130 and the second coating layer 140 Since the operator can easily identify the wear degree of the area corresponding to the operation part 120, the replacement timing of the ultrasonic scaler tip 100 can be accurately determined.
The operating part 120 and the main body 110 are formed to be separated by the color difference of the first coating layer 130 and the second coating layer 140 respectively in the present embodiment, The borderline may be marked with a laser at the borderline so that the boundary of the borderline can be clearly identified.
Figures 7 and 8 show a second embodiment of the tip 200 for an ultrasonic scaler.
The tip 200 of the ultrasonic scaler according to the present embodiment has the boundary display unit 230 at the boundary between the operation unit 220 and the main body 210 in order to further increase the discrimination power of the boundary point between the operation unit 220 and the main body 210 Respectively.
The first coating layer 240, the second coating layer 250, and the third coating layer 260 are sequentially coated on the tip 200 for the ultrasonic scaler of the present embodiment for forming the boundary display part 230. [
More specifically, the first coating layer 240 is first formed on the front surface of the operation part 220 and the coating layer. Then, the second coating layer 250 is coated on the remaining part of the operation part 220, . The third cap layer 260 is further formed with the second cap extended from the actuating portion 220 toward the predetermined length body 210 so as to cover the end portions of the actuating portion 220 and the main body 210 .
Of course, the first coating layer 240, the second coating layer 250, and the third coating layer 260 may be coated with a coloring material.
7, when the first coating layer 240, the second coating layer 250, and the third coating layer 260 are formed, the operation portion 220 is coated with the first coating layer 240, The color of the coating forming the third coating layer 240 is colored and the body 210 is colored of the coating material forming the last coated third coating layer 260. The second coating layer 250 exposed between the third coating layer 260 and the first coating layer 240 is divided into a boundary display part 230 indicating the boundary between the operation part 220 and the main body 210 So that the boundary between the operation unit 220 and the main body 210 can be more clearly identified.
The process of manufacturing the ultrasonic scaler tip 200 of this embodiment is as follows.
The main body 210 is fastened to the jig as shown in FIG. 9 and then the chamber 320 is closed to form the first coating layer 240 on the entire body 210 and the operation part 220. After the first cap is mounted to cover the actuating part 220, a second coating layer 250 is formed. After the second coating layer 250 is formed, the second cap is mounted on the operation part 220 and the main body 210 so as to cover the predetermined length, and then the third coating layer 260 is formed.
As described above, when the coating is performed in three stages, the operation unit 220, the main body 210, and the boundary display unit 230 are disposed on the first coating layer 240, the third coating layer 260, and the second coating layer 250, It becomes possible to clearly distinguish each part while coloring each coating material formed.
The apparatus for manufacturing the ultrasonic scaler tip 200 of this embodiment includes two kinds of caps, that is, a cap mounting portion for mounting the first cap and the second cap respectively, and injection nozzles for spraying three kinds of coating materials And other configurations are the same as those of the manufacturing apparatus 300 of the first embodiment, so that the illustration and description of the apparatus are omitted.
Since the ultrasonic scaler tips 100 and 200 according to the present invention described above can easily visually recognize whether or not the abrasion of the operating parts 120 and 220 reaches the abrasion limit line, the ultrasonic scaler tips 100, 200 can be accurately determined.
