For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0022] Combination Figure 1 - Figure 4, a tooth scraper, including a handle 10, a first scraper 20, and a second scraper 30; one end of the handle 10 is fixedly connected to the first scraper 20, and the other end of the handle 10 relative to the first scraper 20 is fixedly connected to the second scraper 30, the blade of the first scraper 20 is a concave structure, and the blade of the second scraper 30 is a hook-shaped structure, the concave structure can fit the neck perimeter contour of the tooth, and the hook-shaped structure can fit the root contour of the tooth.

[0023] In the above scheme, the tooth scaler in the present application combines the scraper for scraping the root of the tooth with the scraper for scraping the neck of the tooth into one, forming a tooth neck and root integrated scaler. The staff can perform tooth scraping operations on the patient by selecting the first scraper 20 and the second scraper 30 of different models and / or sizes, wherein the first scraper 20 is used to scrape the surface of the tooth periphery, and the second scraper 30 is used to scrape the root surface of the tooth, which satisfies the scraping operations in multiple directions of the periodontal part, making it easier to form a smooth, flat surface with good tissue compatibility under the gums of the teeth.

[0024] The handle ends of the first scraper 20 and the second scraper 30 are fixedly connected to the rotary cover 11, and the cover edge of the rotary cover 11 is fixedly connected to the two ends of the handle 10. The handle ends of the first scraper 20 and the second scraper 30 are fixedly connected to the rotary cover 11. On the one hand, the first scraper 20 and the second scraper 30 are indirectly connected to the handle 10, so as to prevent the scraper and the handle 10 from falling off during tooth scaling. On the other hand, the present application does not limit the specific fixed connection method of the first scraper 20, the second scraper 30 and the rotary cover 11, which can be threaded connection or clamping connection. The purpose is to facilitate the disassembly and replacement of the first scraper 20, the second scraper 30 and the handle 10 and the rotary cover 11, and to facilitate periodontal scaling in multiple directions by replacing scrapers of different models and sizes.

[0025] An anti-slip sleeve 12 is sleeved on one end of the handle 10 near the rotary cover 11. The purpose of such a setting is, on the one hand, to facilitate the operator to hold the dental scaler in the present application, and on the other hand, the operator usually holds the handle 10 of the dental scaler in the posture of holding a pen and wearing gloves, and the setting of the anti-slip sleeve 12 can increase the friction between the fingers and the handle 10, making the handle 10 more secure. The cover edge of the rotary cover 11 is sleeved on the anti-slip sleeve 12, and the purpose of such a setting is to make the connection between the rotary cover 11 and the handle 10 more stable, and on the other hand, to form a closed environment in the cavity 102 to prevent the blades of the first scraper 20 and the second scraper 30 from rusting.

[0026] A convex strip 101 extends from the outer side of the middle of the handle 10 along the axial direction of the handle 10, and the spiral of the convex strip 101 extends to the edge of the anti-slip sleeve 12. The purpose of this arrangement is to further increase the friction between the operator's fingers and the handle 10, making it easier to take and use the dental scaler.

[0027] The middle inner side of the handle 10 is provided with a cavity 102 for accommodating the first scraper 20 and the second scraper 30 along its axial direction, and both ends of the cavity 102 extend to both ends of the handle 10. The middle inner side of the handle 10 of the dental scaler in the present application is hollow, which facilitates the storage of the used first scraper 20 and / or the second scraper 30 in the internal cavity of the handle 10 to ensure a safe operating environment for the dental scaler.

[0028] like Figure 3a , Figure 3b As shown, the concave structure is one or more of a bridge arch shape and a sledge shape. It should be noted that the subgingival periphery of the tooth is an irregular curved surface. The first scraper 20 in the present application is used to scrape the subgingival periphery of the tooth. The concave structure can be a bridge arch shape or a sledge shape. By using the first scraper with different structural shapes to scrape the periphery of the tooth, it is ensured that the dirt such as tartar and bacterial plaque on the subgingival periphery of the tooth is scraped away, thereby forming a smooth, flat, and well-tissue-compatible tooth periphery.

[0029] like Figure 4a , Figure 4b As shown, the cross-sectional profile of the blade of the second scraper 30 is L-shaped, J-shaped or one or more of the above.

[0030] It should be noted that the subgingival periphery of the teeth is conical, and the first scraper 20 in the present application is used to scrape the subgingival root surface of the teeth, and the hook-shaped structure can be L-shaped or J-shaped to fit the surface of the root of the teeth to ensure that tartar, plaque and other dirt on the subgingival root surface of the teeth are scraped off, thereby forming a smooth, flat root surface with good tissue compatibility.

[0031] The tooth scraper in the present application is an integrated structure formed by a first scraper 20, a second scraper 30, a handle 10, and a screw cap 11 fixedly connected to both ends of the handle 10. It is small in size and easy to take and use. The handle ends of the first scraper 20 and the second scraper 30 are fixedly connected to the screw cap 11, so that the first scraper 20 and the second scraper 30 are indirectly connected to the handle 10, which is convenient for installation and disassembly between the first scraper 20, the second scraper 30, the screw cap 11, and the handle 10. The teeth can also be scraped under the gums by replacing the first scraper 20 and the second scraper 30 of different models and / or sizes, and the use scenarios are rich. The convex strip 101 set in the middle of the handle 10 also makes it more firm when the staff holds the handle 10, ensuring a safe use environment for the tooth scraper. In addition, the handle 10 in the embodiment of the present application is cylindrical, and the inner side of the middle part is hollow, so as to facilitate the storage or collection of the scraper after the tooth scraping operation is completed.

[0032] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.

[0033] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit the present application. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features thereof may be replaced by equivalents.
