Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, and particularly relates to a digging spoon for cleaning the germinal centers of tooth extraction sites of upper and lower jaws of rabbits. Background Art

[0002] The germinal center of rabbit teeth is located in the tooth socket. The germinal center of rabbit teeth refers to the dental papilla during tooth germ development, which has the function of controlling the shape of rabbit teeth. When the experimenters are doing experiments such as rabbit upper and lower jaw tooth extraction site preservation or rabbit upper and lower jaw anterior teeth immediate implant model construction, the rabbit's upper and lower teeth need to be removed; after the teeth are removed, in order to prevent subsequent teeth from growing out, the experimenters need to remove the germinal center of the rabbit teeth. At present, the experimenters use a digging spoon to extend into the tooth socket and destroy the germinal center by scraping; however, the front end of the current digging spoon is right-angled and the lines are straight. For example, the Chinese patent with application number 202010556240.5 discloses an improved oral dental scraper, and the front end of the digging spoon (scraper) is relatively straight; and the rabbit's tooth socket is arc-shaped, which makes it difficult for the front end of the digging spoon to enter the rabbit's tooth socket, which easily leads to the inability to completely remove the germinal center residue of the rabbit tooth; and the digging spoon is easy to cause unnecessary damage to other tissues in the tooth socket (such as the labial bone wall) during the insertion process. Utility Model Content

[0003] The utility model aims to provide a digging spoon for removing germinal centers at tooth extraction sites of upper and lower jaws of rabbits, which can efficiently remove germinal centers and reduce damage to other tissues.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a scraping spoon for removing germinal centers of rabbit upper and lower jaw tooth extraction sites, comprising a handle, wherein the two ends of the handle are respectively provided with an upper jaw scraping handle and a lower jaw scraping handle, wherein the upper jaw scraping handle comprises a first straight portion, a first oblique portion and a first curved portion in sequence from the side close to the handle to the side away from the handle, and the lower jaw scraping handle comprises a second straight portion, a second oblique portion and a second curved portion in sequence from the side close to the handle to the side away from the handle, wherein the ends of the first curved portion and the second curved portion are both provided with scraping spoons, and the curvature of the first curved portion is greater than the curvature of the second curved portion.

[0005] This solution provides a first curved portion and a second curved portion, and the first curved portion and the second curved portion have an arc shape that matches the natural curvature of the rabbit teeth, which can ensure that the first curved portion and the second curved portion can smoothly enter the tooth extraction sites of the upper and lower jaws along the contour of the tooth socket, so that the scraper can more accurately destroy the germinal center inside the tooth socket and remove residues (such as broken teeth). At the same time, since the first curved portion and the second curved portion can smoothly enter the tooth socket, damage to other tissues can be reduced. In addition, the first curved portion and the second curved portion have different curvatures, so that they can be applied to the upper and lower teeth of rabbits, and have better versatility.

[0006] Preferably, the curvature of the first curved portion is π / 2, and the curvature of the second curved portion is π / 3, so as to adapt to the natural curvature of the upper and lower teeth of the rabbit.

[0007] Preferably, the scraper is in the shape of a spoon, and a plurality of scraping teeth protruding outward are provided at the end of the scraper.

[0008] The scraper is in the shape of a spoon, which can facilitate digging out the damaged tissue of the germinal center. The scraping teeth are arranged at the end of the scraper, which can facilitate the destruction of the germinal center.

[0009] Preferably, the circumferential outer edge of the scraper tooth is arc-shaped.

[0010] The circumferential outer edge of the scraper tooth is in an arc shape, so as to avoid the first curved portion and the second curved portion from causing damage to other tissues during the process of extending into the tooth socket.

[0011] Preferably, thread-shaped convex strips are provided on the circumferential outer walls of the first curved portion and the second curved portion at one end close to the scraper.

[0012] The tissue of the germinal center is not only at the bottom of the tooth socket, but there is also some tissue around the bottom of the tooth socket. By providing threaded convex strips on the circumferential outer wall of the first and second curved parts close to one end of the scraper, the bottom of the tooth socket can be cleaned around.

[0013] Preferably, the angle between the first straight portion and the first oblique portion and the angle between the second straight portion and the second oblique portion are both 115°-125°, which is convenient for experimenters to operate.

[0014] Preferably, the lengths of the first curved portion and the second curved portion are both 2.5 cm to 3.5 cm.

[0015] The length of the rabbit tooth socket is about 2.5cm-3.5cm to accommodate the rabbit tooth socket.

[0016] The utility model has the advantages of being able to efficiently remove the germinal center and reducing damage to other tissues. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The utility model is further described below based on the accompanying drawings and specific embodiments.

[0021] like Figure 1 As shown, this embodiment discloses a scraper for removing the germinal center of the upper and lower jaws of rabbits, comprising a handle 1, and the two ends of the handle 1 are respectively provided with an upper jaw scraper handle and a lower jaw scraper handle, wherein the upper jaw scraper handle includes a first straight portion 21, a first oblique portion 22 and a first curved portion 23 from the side close to the handle 1 to the side away from the handle 1, and the lower jaw scraper handle includes a second straight portion 31, a second oblique portion 32 and a second curved portion 33 from the side close to the handle 1 to the side away from the handle 1, and the ends of the first curved portion 23 and the second curved portion 33 are both provided with a scraper 4, and the curvature of the first curved portion 23 is greater than the curvature of the second curved portion 33, the curvature of the first curved portion 23 is π / 2, and the curvature of the second curved portion 33 is π / 3. The angle between the first straight portion 21 and the first oblique portion 22 is 120°, and the angle between the second straight portion 31 and the second oblique portion 32 is 120°. The lengths of the first curved portion 23 and the second curved portion 33 are both 3 cm.

[0022] like Figure 1 and Figure 2 As shown, the scraper 4 is in the shape of a spoon (not shown in the figure), wherein the spoon shape is any existing spoon shape that can clean the tooth socket and dig out the tissue. The end of the scraper 4 is provided with a plurality of scraping teeth 5 protruding outward, and the circumferential outer edge of the scraping teeth 5 is in an arc shape. The ends of the first curved portion 23 and the second curved portion 33 are both provided with the scraper 4, and the circumferential outer wall of the first curved portion 23 and the second curved portion 33 close to the scraper 4 is provided with a threaded convex strip 6.

[0023] In the actual operation, after the extraction of the rabbit's upper teeth is completed, the experimenter slowly extends the first curved portion 23 into the tooth socket of the rabbit's upper teeth. When the scraper 4 reaches the germinal center in the tooth socket of the rabbit's upper teeth, the experimenter destroys the germinal center by scraping, and takes the destroyed germinal center tissue out of the tooth socket. After the extraction of the rabbit's lower indentation is completed, the experimenter slowly extends the second curved portion 33 into the tooth socket of the rabbit's lower teeth. When the scraper 4 reaches the germinal center in the tooth socket of the rabbit's lower teeth, the experimenter destroys the germinal center by scraping, and takes the destroyed germinal center tissue out of the tooth socket.
