Technical Field
[0001] The utility model relates to the field of oral medicine and dentistry, in particular to a dental pulp tissue extractor. Background Art
[0002] The pulp tissue is located in the pulp cavity inside the tooth. The appearance of the pulp cavity is roughly similar to the shape of the tooth body. The pulp cavity at the crown of the tooth is larger, called the pulp chamber, and the pulp cavity at the root of the tooth is smaller, called the root canal. There is a small hole at the root apex, called the apical foramen. The pulp tissue mainly contains nerves, blood vessels, lymph and connective tissue, as well as odontoblasts arranged around the periphery of the pulp, whose function is to produce dentin. Since the hard tissue of the deciduous teeth is thin and the dentinal tubules are thick, bacteria and their metabolites can easily enter deep layers and infect the pulp. In order to remove the infected coronal pulp, maintain the normal vitality of the root pulp, and enable the odontoblasts in the pulp to perform normal functions during the physiological shedding period of the deciduous teeth, maintain its physiological absorption, and thus complete the replacement of deciduous and permanent teeth, the infected pulp tissue needs to be excavated.
[0003] During use, the existing dental pulp tissue extractor cannot adjust the extractor body. When it is necessary to extract the infected dental pulp tissue deep in the patient's mouth, it is necessary to manually hold the extractor body and constantly adjust the manual insertion distance before inserting it into the deep part of the patient's mouth to complete the extraction of the infected dental pulp tissue of the patient. However, the process of manually holding the extractor body and constantly adjusting the extraction distance is rather cumbersome, which is inconvenient when extracting the infected dental pulp tissue of the patient.
[0004] Therefore, it is particularly necessary to propose a dental pulp tissue extractor that is easy to adjust. Utility Model Content
[0005] In order to overcome the above-mentioned shortcomings of the prior art, the utility model provides a dental pulp tissue extractor which is easy to adjust.
[0006] In order to solve the above technical problems, the utility model provides a dental pulp tissue extractor, comprising a connecting rod, a sliding rod, a fixed rod, a digging plate, a blade and a miniature camera, wherein the connecting rod is a supporting rod body, and a threaded groove is provided on the inner side of the connecting rod; the sliding rod is slidably connected to the outer side of the connecting rod; the fixed rod is threadedly connected to the threaded groove provided on the inner side of the connecting rod, and one side of the fixed rod is extended outward; the digging plate is fixedly connected to one side of the fixed rod, and the digging plate is spoon-shaped; the blade is fixedly connected to the inner front side of the digging plate; the miniature camera is fixedly installed between the fixed rod and the digging plate, and the camera end of the miniature camera is exposed outward.
[0007] Preferably, a blocking block is further included, which is fixedly connected to the inner side of the sliding rod, and the blocking block is in sliding contact with the connecting rod.
[0008] Preferably, it also includes a connecting ring and a micro lamp, wherein the connecting ring is fixedly connected to the front side of the connecting rod; the micro lamp is installed on the top of the connecting ring, and the micro lamp is adjacent to the fixing rod.

[0011] Preferably, anti-slip teeth are provided on the outer side of the anti-slip sleeve.
[0012] Beneficial effects: 1. By holding the anti-slip sleeve and manipulating the connecting rod, the blade on the digging plate is used to dig out the decayed pulp tissue in the patient's teeth. The sliding rod is manually pulled to drive the protective ring to slide and stretch on the outside of the connecting rod, making it more convenient for the doctor to dig out the patient's pulp tissue;
[0013] 2. When the sliding rod is extended and stretched, the blocking block limits the pulling of the sliding rod to prevent the sliding rod from sliding excessively outside the connecting rod, so that the sliding rod is out of contact with the connecting rod, and the anti-slip teeth on the anti-slip sleeve make the doctor's hand-held operation more stable, thereby making it easier for the doctor to complete the operation using the excavator.

[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0021] Embodiment: A dental pulp tissue extractor, such as Figure 1-Figure 5 As shown, it includes a connecting rod 1, a sliding rod 2, a fixed rod 3, a digging plate 4, a blade 41 and a micro camera 5. A threaded groove is provided on the inner front side of the connecting rod 1 for connecting components through threads; the sliding rod 2 is slidably connected to the outer side of the connecting rod 1; the fixed rod 3 is detachably connected to the threaded groove provided on the inner side of the connecting rod 1 through threads, and the front end of the fixed rod 3 is vertically extended outward; the digging plate 4 is connected to one side of the fixed rod 3 through micro screws, and the digging plate 4 is spoon-shaped. When the digging plate 4 needs to be replaced, the fixed rod 3 is directly removed by rotating the threads on the inner front side of the connecting rod 1 to facilitate the disassembly and replacement of the digging plate 4; the blade 41 is connected to the inner front side of the digging plate 4 through micro screws; the micro camera 5 is detachably installed between the fixed rod 3 and the digging plate 4 through a mounting piece, and a waterproof coating is coated on the micro camera 5 to prevent water from entering the micro camera 5 when the fixed rod 3 is disassembled, and the camera end of the micro camera 5 is exposed outward, so as to detect the oral environment during use.
[0022] like Figure 4 and Figure 5 As shown, a blocking block 6 is also included. The blocking block 6 is connected to the inner side of the sliding rod 2 by glue. The blocking block 6 is made of rubber material, and the blocking block 6 is in sliding contact with the connecting rod 1. The surface of the connecting rod 1 is frictionally limited by the blocking block 6 to prevent the sliding rod 2 from sliding out of the outside of the connecting rod 1.
[0023] like Figure 3-Figure 5 As shown, it also includes a connecting ring 7 and a micro light 8. The connecting ring 7 is connected to the front side of the connecting rod 1 through a fixing part, and the connecting ring is used for the installation of the components; the micro light 8 is detachably installed on the top of the connecting ring 7 through micro screws. The micro light 8 is made of waterproof material to prevent the micro light 8 from getting wet when the scraper body is cleaned, and the micro light 8 is close to the front side of the fixing rod 3, which makes it easier to assist the micro camera 5 in operation.
[0024] like Figure 4 As shown, a protective ring 9 is also included. The protective ring 9 is connected to the front end of the sliding rod 2, and the protective ring 9 is in sliding contact with the connecting rod 1. The protective ring 9 is made of a sealing material to prevent liquid from penetrating between the connecting rod 1 and the sliding rod 2.
[0025] like Figure 1 and Figure 5 As shown, an anti-slip cover 10 is also included. The anti-slip cover 10 is connected to the outside of the sliding rod 2 by glue, and the anti-slip cover 10 is made of high-temperature resistant silicone rubber material to prevent the anti-slip cover 10 from deforming after being heated and affecting the use effect. An annular semi-spherical convex anti-slip teeth are evenly arranged on the outside of the anti-slip cover 10. The semi-spherical convex anti-slip teeth on the anti-slip cover 10 make it easier to hold.
[0026] When it is necessary to use the excavator to excavate the infected pulp tissue of the patient, first place the excavator in the placement tray of the disinfection box, then start the disinfection box to disinfect the excavator. After the disinfection is completed, take the excavator out of the placement tray of the disinfection box, and start the micro camera 5 and the micro lamp 8. The micro camera 5 can detect the dental conditions inside the patient's mouth. The micro camera 5 can be remotely connected to the projection screen to feed back the dental conditions inside the patient's mouth on the projection screen. The micro lamp 8 can assist the micro camera 5 in detecting, and the micro lamp 8 can further illuminate the patient's mouth, so that the doctor can find some flashes or bright spots on the patient's teeth through the light before treatment, so as to judge whether the pulp cavity of the tooth has been exposed, thereby judging the severity of the patient's condition. When the decayed pulp tissue in the patient's teeth is found, the anti-slip sleeve 10 is held by hand to control the connecting rod 1 to use the blade 41 on the excavating plate 4 to excavate the decayed pulp tissue in the patient's teeth. During the excavation, when it is necessary to further explore the inside of the patient's oral cavity, the sliding rod 2 is manually pulled to drive the protective ring 9 to slide and stretch outside the connecting rod 1, so that the doctor can more conveniently excavate the patient's pulp tissue. When the sliding rod 2 slides, stretches and stretches outside the connecting rod 1, the blocking block 6 will limit the pulling of the sliding rod 2 to prevent the sliding rod 2 from sliding excessively outside the connecting rod 1, so that the sliding rod 2 is out of contact with the connecting rod 1, and the anti-slip teeth on the anti-slip sleeve 10 make the doctor's hand-held operation more stable, thereby making it easier to excavate the patient's pulp tissue. After the infected pulp tissue of the patient is excavated, the excavator needs to be cleaned and disinfected. When the disinfectant water soaks into the surface of the excavator, the protective ring 9 prevents the disinfectant water from entering the sliding rod 2, so that the sliding rod 2 and the connecting rod 1 are sealed. After the cleaning and disinfection of the excavator are completed, the excavator is placed in the sterile warehouse to complete the use of the excavator.
