Description

Ultrasonic Scaler Tips and Manufacturing Method Thereof

The present invention relates to an ultrasonic scaler tip and a method of manufacturing the same, and more particularly, to an ultrasonic scaler tip and a method of manufacturing the same that can easily check the wear of the end.

Ultrasonic Scaler Driver generates ultrasonic waves by generating mechanical vibration from power pressure by using piezoelectric phenomenon that converts electrical energy into mechanical energy, and can use this ultrasonic wave to remove dental plaque at teeth, affected part or procedure location. Device to ensure that

Conventional ultrasonic scaler 10 is a tip 110 is coupled to the tip as shown in Figure 1, this tip 11 as shown in Figure 2 so as to maximize the ultrasonic vibration efficiency at the distal end Bent

The tip 11 is typically made of iron, copper, titanium, metal alloys, etc. If the use of the tip 110 is repeated, wear occurs.

The performance of the tip 11 is closely related to the degree of wear. Typically, the performance of the tip 11 decreases by 25% when the end of the tip 11 wears, and when the 2mm decreases, the performance decreases by 50%. . Therefore, it is recommended to set the wear limit of the tip 11 to 2mm normally and to replace it when the tip 11 reaches the wear limit.

By the way, the conventional tip 11 for the scaler is not only made of the same material, including the distal end portion, but also does not have a special mark is formed to identify how much the wear progressed to the identification card as shown in Figure 3 (20) was used.

The identification card 20 has a tip groove 21 formed therein, and is marked with a reference line 22 indicating a wear limit point. The user inserted the tip 11 into the tip groove 21 of the identification card 20 and checked whether the tip 11 was worn over the reference line 22.

However, since it is very cumbersome to check the wear state of the tip 11 every time using the identification card 20 in the process of using the ultrasonic scaler, the user does not check the wear state through the identification card 20 in the field. It was often judged by the sense of replacement time.

The present invention has been made to solve the above problems, and provides an ultrasonic scaler tip and a method of manufacturing the same that can easily identify the tip replacement length of the ultrasonic scaler tip by easily identifying the end wear length. There is this.

A first coating layer is formed on the entire body and the operating part to distinguish the main body and the operating part, and a second coating layer having a color distinct from the first coating layer is formed on the first coating layer on the main body except the operating part. It is preferable.

At the boundary point that is the boundary between the main body and the operating part, a landmark view portion may be formed which is respectively distinguished from the operating part and the main body so as to increase the discriminating power of the boundary between the operating part and the main body.

The landmark view portion may be formed by laser marking a portion that is a boundary between the first coating layer and the second coating layer.

A first coating layer is formed on the main body, the entire operation part and the landmark view part, and a second coating layer is formed on the landmark view part and the main body except the operating part, and the second coating layer is formed on the main body except the operating part and the landmark view part. A third coating layer is formed on the second coating layer, wherein the first coating layer, the second coating layer, and the third coating layer are formed in different colors that are different from each other, and are exposed to the outside between the third coating layer and the first coating layer. It is preferable that the landmark view is formed by the second coating layer.

The manufacturing method of the tip for the ultrasonic scaler of the present invention is to be mounted on the ultrasonic scaler to perform a scaling operation, and includes a main body mounted on the ultrasonic scaler and an operation unit formed at an end of the main body and in contact with the scaling target surface to perform the scaling operation. In the tip for the ultrasonic scaler, the first coating step of forming a first coating layer on the entire body and the operating part, and the first cap mounting step of mounting a first cap on the operating part after the first coating layer is formed And a second coating step of forming a second coating layer separated from the first coating layer on the main body in a state where the first cap is mounted.

The jig mounting step of fixing the lower portion of the main body to the jig before the first coating step to fix the tip for the ultrasonic scaler may be further included.
