[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this utility model, not all embodiments.

[0022] Reference Figures 1 to 4 As shown in the figure, this utility model embodiment provides a periodontal scaling device.

[0023] The periodontal curette includes two scrapers 100 and a handle 200, with the two scrapers 100 respectively mounted at both ends of the handle 200.

[0024] Each scraper 100 has a working blade 110 at its end, and a depth mark 120 is provided on the outer circumferential surface of each scraper 100. The depth mark 120 surrounds the scraper 100 in a circle, and the distance between the depth mark 120 and the working blade 110 is between 3mm and 6mm.

[0025] The depth marking 120 can be engraved on the outer peripheral surface of the scraper 100 using a laser engraving device to create a frosted surface, making the depth marking 120 distinguishable from the smooth metal surface of the rest of the scraper 100. Alternatively, a spraying process can be used to apply colored paint to the outer peripheral surface of the scraper 100 to form the depth marking 120. Alternatively, a surface anodizing dyeing process can be used, where the plating on the surface of the scraper 100 is colored by the electric field during electrolysis.

[0026] Each scraper 100 is provided with a screw 130, and the two ends of the handle 200 are respectively provided with screw holes 220. The screw 130 is screwed into the screw holes 220 so that the two scrapers 100 can be detachably connected to the two ends of the handle 200 respectively.

[0027] Alternatively, in some embodiments, each scraper 100 is provided with a connecting rod at its end, and each connecting rod has an outwardly protruding buckle with a spring-loaded capability on its outer side wall. The two ends of the handle 200 are respectively provided with connecting holes, and the inner side wall of the connecting holes is provided with buckle grooves. After the connecting rod is inserted into the connecting hole, it is snapped into the buckle groove by the buckle, so that the two scrapers 100 can be detachably connected to the two ends of the handle 200 respectively.

[0028] In this embodiment, a metal rod is provided inside the handle 200, and a soft silicone layer 201 is covered on the outside of the handle 200 to improve the grip feel of the handle 200. Two anti-slip structures 202 are provided on the outer surface of the soft silicone layer 201. The two anti-slip structures 202 are respectively provided at the two ends of the handle 200, so that the anti-slip structures 202 are close to the scraper 100. The anti-slip structures 202 are composed of multiple uneven curved surfaces, which can reduce the problem of doctors slipping when holding the handle 200.

[0029] Reference Figure 1 and Figure 2As shown, the scraper 100 uses the side where the working blade 110 is located as its working surface 101. With the working surface 101 facing the viewing angle, the side of the periodontal scaler facing the observer is the operating surface 10. Since the periodontal scaler has two scrapers 100 and the working surfaces 101 of the two scrapers 100 face opposite directions, the periodontal scaler has two operating surfaces 10. Two working surface markings 210 are provided on the outer wall of the handle 200. The two working surface markings 210 are respectively located at the end of the handle 200 near the scraper 100 and on the side of the handle 200 facing the two operating surfaces 10.

[0030] Reference Figure 1 and Figure 2 As shown, the periodontal scaling device is arranged in the vertical direction. The working surface 101 of the upper scaling blade 100 faces the observer's view and the upper working surface mark 210 faces the observer's view. The working surface 101 of the lower scaling blade 100 faces away from the observer's view and the lower working surface mark 210 faces away from the observer's view.

[0031] When using a periodontal scaling instrument, the dentist uses the working surface marking 210 on the outer side of the handle 200 to determine the working blade 110 of the scaling blade 100, so as to quickly identify the position of the working blade 110. When using the working blade 110 of the scaling blade 100 to penetrate into the patient's gums for scaling, the depth marking 120 on the outer side of the scaling blade 100 can be used to determine the depth of penetration of the working blade 110, thereby improving work efficiency.

[0032] In some embodiments, refer to Figure 4 As shown, the handle 200 includes a first rod portion 203, a second rod portion 204, a connector 205, a first fastener 206, and a second fastener 207.

[0033] The first rod 203 has a first working end 2031 and a first connecting end 2032 at its two ends. The end face of the first working end 2031 is provided with a screw hole 220. The first scraper 100 is connected to the screw hole 220 of the first working end 2031 by a screw 130. The second rod 204 has a second working end 2041 and a second connecting end 2042 at its two ends. The end face of the second working end 2041 is provided with a screw hole 220. The second scraper 100 is connected to the screw hole 220 of the second working end 2041 by a screw 130.

[0034] The end face of the first connecting end 2032 is provided with a first insertion hole 2033, and the side wall of the first insertion hole 2033 is provided with a first through hole 2034 extending outward. The end face of the second connecting end 2042 is provided with a second insertion hole, and the side wall of the second insertion hole is provided with a second through hole 2044 extending outward.

[0035] The connector 205 is cylindrical. The side wall of the connector 205 is provided with a first threaded hole 2051 and a second threaded hole 2052. The first threaded hole 2051 and the second threaded hole 2052 are respectively close to the two ends of the connector 205. The two ends of the connector 205 are respectively inserted into the first insertion hole 2033 and the second insertion hole. The end face of the first connecting end 2032 abuts against the end face of the second connecting end 2042, so that the first threaded hole 2051 is directly opposite the first through hole 2034 and the second threaded hole 2052 is directly opposite the second through hole 2044.

[0036] Both the first fastener 206 and the second fastener 207 are screws. The first fastener 206 passes through the first through hole 2034 and is screwed into the first threaded hole 2051 of the connector 205. The second fastener 207 passes through the second through hole 2044 and is screwed into the second threaded hole 2052 of the connector 205.

[0037] During production, the connector 205 is connected to the first connecting end 2032 of the first rod 203 using the first fastener 206, and the connector 205 is connected to the second connecting end 2042 of the second rod 204 using the second fastener 207. Then, two scrapers 100 are respectively installed to the first working end 2031 of the first rod 203 and the second working end 2041 of the second rod 204. When the first rod 203 malfunctions, the scraper 100 connected to the first rod 203 by the first fastener 206 can be removed, and the first rod 203 can be replaced. When the second rod 204 malfunctions, the scraper 100 connected to the second rod 204 by the second fastener 207 can be removed, and the second rod 204 can be replaced. When any scraper 100 malfunctions, it can be directly replaced. Therefore, if a component of the periodontal scaling device malfunctions, the entire periodontal scaling device does not need to be scrapped; only the malfunctioning component needs to be replaced, reducing waste.

[0038] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
