[0042] Embodiment 1:

[0043] like Figures 3 to 8 As shown:

[0044] A scraper comprises a handle 1 and a working tip 2; wherein:

[0045] The working tip 2 is arranged at the end of the handle 1. A convex portion A21 for debridement of the root surface recessed area is arranged on the side wall of the working tip 2. The side of the convex portion A21 away from the working tip 2 is arc-shaped. The cross-section of the convex portion A21 is wedge-shaped. Figure 3 , Figure 4 and Figure 5 .

[0046] The convex portion A disposed on the working tip 2 of the scraper is in an arc shape on the side away from the working tip 2, which can perfectly fit the concave area of ​​the tooth root surface, see Figure 6 During the scaling process, the convex portion A21 can easily remove the infection in the recessed area of ​​the tooth root surface, which is very helpful for thorough debridement during treatment, making debridement simpler and more complete, thereby reducing the infection rate after periodontal treatment and increasing the success rate of dental lesion treatment.

[0047] Although the tip of the scraper in the prior art can also extend into the depressed area of ​​the tooth root surface to scrape the area, it requires medical staff to do it repeatedly and multiple times, and the debridement effect cannot be guaranteed; while the convex portion A21 in this embodiment can perfectly fit the depressed area of ​​the tooth root surface, and can quickly complete the scraping of the depressed area of ​​the tooth root surface, without the need to scrape the depressed area of ​​the tooth root surface repeatedly and multiple times, thereby improving the scraping efficiency of medical staff.

[0048] It should be noted that the wedge-shaped cross-section of the convex portion A21 means that the width of the cross-section of the end of the convex portion A21 away from the working tip 2 is smaller than the width of the cross-section of the end of the convex portion A21 close to the working tip 2, see Figure 5 More specifically, the upper end surface of the convex portion A21 (the side facing upward during scraping, that is, Figure 5 The lower end surface of the convex portion A21 (the side facing downward during scraping) is a downwardly concave arc surface, and the lower end surface of the convex portion A21 (the side facing upward during scraping) is a downwardly concave arc surface. Figure 5 The upper side of the convex portion A21 is a downwardly convex arc surface, and the end of the lower end surface of the convex portion A21 away from the working tip 2 gradually approaches and connects to the end of the upper end surface of the convex portion A21 away from the working tip 2.

[0049] Optimally, the scraper also includes a lighting lamp cover 3, see Figure 8 The lighting lamp cover 3 is a circular cylindrical structure with openings at both ends, and the lighting lamp cover 3 is detachably mounted on the handle 1;

[0050] The bright light emitted by the lighting lamp sleeve 3 can illuminate the darker area (the root surface depression is located at the position covered by the periodontal pocket, the narrow area), which is convenient for medical staff to see the scaling area clearly and better complete the scaling work.

[0051] It should be noted that both ends of the above-mentioned lighting lamp cover 3 are light-emitting parts.

[0052] Specifically, the lighting lamp cover 3 includes a cover body 31, an LED lamp 32, a battery and an on / off switch 33, see Figure 8 ;in,

[0053] The LED lamp 32 is a ring-shaped structure, and its diameter matches the diameter of the sleeve body 31. There are two LED lamps 32, and the two LED lamps 32 are respectively arranged at both ends of the sleeve body 31;

[0054] The battery (not shown) is a button battery or other small power supply that can store electric energy. The battery is arranged inside the sleeve body 31 and can provide the LED lamp 32 with the electric energy required for its operation.

[0055] The on / off switch 33 is arranged on the outer surface of the sleeve body 31, so as to facilitate the operation of medical personnel;

[0056] The battery is electrically connected to the LED light 32 via the on / off switch 33. The LED light 32 can be turned on and / or off via the on / off switch 33, making the use of the scraper more convenient.

[0057] Optimally, the sleeve body 31 is provided with a charging interface that is plugged into the adapter, and the charging interface is electrically connected to the battery, so that the lighting lamp sleeve 3 can be charged and used repeatedly.

[0058] Optimally, the surface of the working tip 2 is provided with a self-cleaning layer; wherein,

[0059] The self-cleaning layer is a super-hydrophobic coating, which can greatly reduce the adhesion of water and other liquids, so that the cleaning of the scraper is more convenient.

[0060] After scraping, a lot of blood will adhere to the surface of the working end of the scraper in the prior art, and it will be difficult to clean after the blood dries up.

[0061] A self-cleaning layer is provided on the surface of the working tip 2 of the scraper in this embodiment. If blood contacts the self-cleaning layer, the blood will drop in the form of beads, or can be removed by simple soaking, making the cleaning of the scraper more convenient.

[0062] Optimally, the surface of the handle 1 is provided with a recessed portion for easy gripping, so that the gripping portion of the handle 1 is ergonomically designed, and the shape, size and curve design of the handle 1 can naturally adapt to the shape of the human hand, reduce the hand pressure during gripping and operation, and reduce the discomfort and hand and wrist fatigue of medical staff during long-term operation.

[0063] Preferably, the weight distribution of the handle 1 and the scraper as a whole should be balanced to avoid the situation where the front is heavy and the back is light, or the front is light and the back is heavy during use, thereby ensuring stability during operation and reducing the burden on the wrist.

[0064] Optimally, the surface of the handle 1 is provided with anti-skid patterns to prevent the scraper from slipping off the hands of medical staff during the scraping process, thereby making the scraper safer when used.

[0065] Optimally, the above-mentioned working tip 2 is provided with scale marks, and the scale marks are arranged at equal intervals from the end of the working tip 2 away from the handle 1 to the end close to the handle 1. Medical staff can know the depth of the working tip 2 through the scale marks on the working tip 2, and control the depth and distance of the working tip 2 entering the periodontal pocket during scraping to ensure safety during scraping.

[0066] Optimally, there are two working tips 2, which are respectively arranged at two ends of the handle 1, and are respectively used for scraping the buccal and lingual sides of the teeth.

[0067] Embodiment 2:

[0069] A curette for debridement of a furcation region, comprising a handle 1 and a working tip 2;

[0070] The working tip 2 is arranged at the end of the handle 1. A convex portion B22 for debridement of the root bifurcation area is arranged on the side wall of the working tip 2. The side of the convex portion B22 away from the working tip 2 is triangular, and the cross-section of the convex portion B22 is wedge-shaped. Fig. 9 , Fig.10 and Fig.11 .

[0071] The front end of the triangular convex part B22 is sharper, and can be extended into the root bifurcation like a pointed spoon to scrape the position of the root bifurcation and remove the infection at the root bifurcation;

[0072] Usually the width of the root bifurcation entrance is 1mm-3mm, and the angle between the two roots and the root bifurcation clamp is between 25° and 45°; the angle range on both sides of the convex portion B22 in this embodiment is 25° to 45°, so as to better adapt to the root bifurcation area of ​​the tooth, so that it can better complete the scaling of the root bifurcation position.

[0073] It should be noted that the wedge-shaped cross-section of the convex portion B22 means that the width of the cross-section of the end of the convex portion B22 away from the working tip 2 is smaller than the width of the cross-section of the end of the convex portion B22 close to the working tip 2; more specifically, the upper end surface of the convex portion B22 (the side facing upward during scraping, i.e. Fig.11 The lower end surface of the convex portion B22 (the side facing downward during scraping) is a downwardly concave arc surface, and the lower end surface of the convex portion B22 (the side facing upward during scraping) is a downwardly concave arc surface. Fig.11The upper side of the convex portion B22 is a downwardly convex arc surface, and the end of the lower end surface of the convex portion B22 away from the working tip 2 gradually approaches and connects to the end of the upper end surface of the convex portion B22 away from the working tip 2.

[0074] In addition, the other structures of the scraper recorded in the embodiment are exactly the same as the other structures of the scraper recorded in Example 1. For details, please refer to the contents in Example 1, and they will not be repeated here.
