Description

Technical Field

[0001] This invention belongs to the field of dental sample testing, and in particular relates to a dental sample digestion system and method. Background Technology

[0002] Measuring the proportion of boron in tooth enamel among people from different regions across the country is of great significance for understanding the impact of dietary culture on teeth in different regions and for protecting teeth. Before measuring the proportion of boron in teeth, the tooth enamel must be digested. First, the tooth enamel needs to be peeled off the teeth. Then, the peeled tooth enamel is ground to about 200 mesh. Finally, it is mixed in a chemical solvent and then placed in a digestion instrument for complete digestion.

[0003] However, in existing technologies, when peeling tooth enamel, diamond wire is used to cut the tooth. After cutting, a scalpel and forceps are used to separate the enamel from the dentin. After separation, the enamel is manually ground. Because the teeth are relatively small, the process of obtaining tooth enamel is difficult and inefficient. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a tooth sample digestion system and method, which solves the problems of high operational difficulty and low efficiency in existing tooth sample digestion systems, which involve cutting teeth with diamond wires when peeling enamel, separating the enamel and dentin with scalpels and tweezers after cutting, and manually grinding the enamel.

[0005] To achieve the above objectives, the present invention provides a tooth sample digestion system, comprising: an enamel separation mechanism, an enamel grinding mechanism, and an enamel digestion mechanism.

[0006] The enamel separation module includes a base, a rotary drive module, a rotating disk, a clamping module, and a grinding separation module. A support frame is fixedly mounted on the base. The rotating disk and the support frame are rotatably connected. The rotary drive module drives the rotating disk to rotate. Several clamping modules are fixedly mounted on the rotating disk to clamp the teeth. The grinding separation module is fixedly connected to the support frame and separates the enamel from the teeth. The enamel grinding mechanism grinds the separated enamel; the digestion mechanism microwaves the detached enamel.

[0007] Because the enamel separation mechanism is equipped with a grinding and separation module, it directly grinds off the enamel from the tooth. The enamel is peeled off in small particles or powder, which is convenient for the subsequent enamel grinding mechanism to grind it. After grinding, the enamel becomes finer, resulting in better and more complete dissolution. Enamel peeling does not require cutting the tooth and can be fully automated, making it highly efficient.

[0008] Optionally, a plurality of clamping modules are arranged in a ring on the rotary seat. Each clamping module includes a rotary seat and an automatic gripper. The automatic gripper is rotatably mounted on the rotary seat, which is fixedly mounted on a rotary disk. The automatic gripper holds the tooth, and the rotary seat can drive the automatic gripper to rotate. During the enamel grinding process, the grinding head grinds the tooth surface, and the tooth itself rotates slowly, allowing for uniform grinding of the entire annular surface of the tooth.

[0009] Optionally, the grinding separation module includes a telescopic component, an actuator arm, a grinding motor, a grinding head, a camera, and a collection cover. The telescopic component and the support frame are fixedly connected. The actuator arm is installed at the telescopic end of the telescopic component, and the grinding head is rotatably mounted at the end of the actuator arm. The actuator arm is a multi-segment articulated arm, which can flexibly drive the grinding head to move back and forth and change the angle of the grinding head relative to the teeth, so as to achieve comprehensive grinding of the teeth by the grinding head. The motor and the actuator arm are fixedly connected, and the grinding motor and the grinding head are drivenly connected. The collection cover is fixedly connected to the end of the telescopic component through a mounting plate. The collection cover has an operating hole, and the grinding head extends into the collection cover. The bottom of the collection cover has a discharge port. The camera is fixedly installed inside the collection cover. When the grinding head is grinding the teeth, the collection cover covers the entire teeth.

[0010] A grinding head is rotated by a grinding motor. During rotation, the enamel on the tooth surface in contact with the grinding head is peeled off. A camera monitors changes in tooth surface color and layering to determine if the enamel has been completely removed. A telescopic mechanism controls the movement of a collection hood. When the telescopic mechanism extends, the collection hood moves away from the tooth; when it retracts, the hood approaches and ultimately covers the tooth, preventing the enamel from splashing. The enamel is collected and discharged from the outlet along the collection hood. After enamel removal from one tooth, the collection hood moves away to move on to the next tooth. The collection hood then moves back to cover the tooth, and the grinding head begins enamel removal on the newly replaced tooth. This automatic switching and enamel removal process results in high efficiency.

[0011] Optionally, the rotary drive module includes a rotary motor, gears, and an external gear ring. The rotary motor is fixedly connected to a support frame, and both the gears and the external gear ring are rotatably connected to the support frame. The output shaft of the rotary motor is coaxially and fixedly connected to the gears. The external gear ring and the gears mesh with each other, and the external gear ring is fixedly connected to a rotating disk. The rotary motor drives the gears to rotate, which in turn drives the external gear ring to rotate, which in turn drives the rotating disk to rotate. The rotating disk then drives the clamping modules on it to rotate. Because multiple clamping modules are provided, multiple teeth can be clamped sequentially. The rotation of the rotating disk enables the switching of teeth, ensuring the continuity of enamel peeling and improving efficiency.

[0012] Optionally, the enamel polishing mechanism includes a linear guide rail, a slider, and a micro-polishing machine; the linear guide rail is fixedly mounted on the base, the slider and the linear guide rail slide together, the micro-polishing machine is fixedly mounted on the slider, and the feed inlet of the micro-polishing machine is connected to the discharge outlet of the collection hood.

[0013] Because it is equipped with a micro grinder, it can grind the enamel discharged from the outlet, so that the enamel dust particles are the required size, which is more efficient than manual grinding.

[0014] Optionally, the collection hood includes a cylindrical section, a conical section, a hood tube, and an air outlet pipe. The discharge port is located at the tip of the conical section, and the operating hole is located in the cylindrical section. The cylindrical section and the conical section are coaxially and fixedly connected. The hood tube is connected to the cylindrical section. When an air blowing pipe is connected to the cylindrical section, the air blowing pipe is tangentially connected to the cylindrical section. The air outlet pipe is coaxial with the cylindrical section and extends into the cylindrical section. A filter screen is provided at the end of the air outlet pipe.

[0015] During operation, the automatic gripper holds the tooth and extends it into the cylindrical section through the cover tube. The grinding head peels off the enamel from the tooth surface. During the peeling process, the air outlet of the blower is directly facing the tooth, and the air blown out by the blower blows away the dust particles ground off the tooth surface, causing them to rotate along the cylindrical wall. Under the action of centrifugal force, the enamel dust particles adhere tightly to the cylinder wall and move downwards under the action of gravity, eventually being discharged from the outlet. The cyclone inside the cylinder is discharged from the exhaust port. Constantly cleaning the tooth surface facilitates monitoring of the enamel peeling process, prevents enamel dust from remaining on the equipment, and ensures that the enamel dust quickly accumulates at the outlet.

[0016] Optionally, the enamel digestion apparatus includes a digestion vessel and a digestion apparatus. The digestion vessel is used to hold the enamel powder after it has been ground by the enamel grinding mechanism, and the digestion apparatus is used to digest the enamel powder. After the ground enamel and chemical solvent have fully combined, they are digested in the digestion apparatus, so that the boron element in the enamel is completely dissolved in the solution, so as to facilitate the subsequent enrichment, collection and measurement of boron element.

[0017] The present invention provides a method for digesting tooth samples, comprising the following steps:

[0018] Enamel separation steps: The tooth is clamped in an automatic gripper. The rotary drive module rotates the gripped tooth to the designated position. A collection cover covers the automatic gripper and the tooth. The actuator arm controls the grinding head to grind the tooth and remove the enamel. The rotating seat rotates slowly during the grinding process so that the grinding head can completely remove the enamel from the tooth surface. The grinding process is monitored by a camera. When the tooth surface color changes to light yellow, it indicates that the enamel on the tooth surface has been cleaned. The actuator arm then moves the grinding head to other parts of the tooth to continue grinding.

[0019] Enamel grinding steps: The ground enamel is collected by a collection cover and enters a micro grinder through the outlet of the collection cover. The micro grinder grinds the enamel to 200 mesh. When the enamel on a tooth is completely removed, the telescopic component moves the collection cover away from the automatic gripper. The rotating drive module moves the next set of teeth into the designated position. The telescopic component moves the collection cover to cover the automatic gripper again. During the movement of the collection cover, the slider drives the micro grinder to move synchronously.

[0020] Digestion steps: Weigh the ground enamel and put it into a digestion vessel. Add a certain amount of nitric acid solution and hydrogen peroxide solution. For every 50 mg of enamel, add 3 ml of 50% nitric acid and 2 ml of 30% hydrogen peroxide and shake. Place the mixed solution into a digestion apparatus for microwave digestion.

[0021] Compared to traditional tooth sample digestion processes, this method improves the efficiency of enamel separation and enamel grinding, thereby increasing experimental efficiency. Attached Figure Description

[0030] Please see Figures 1-4 The present invention provides an embodiment of a tooth sample digestion system, comprising: an enamel separation mechanism, an enamel grinding mechanism 7, and an enamel digestion mechanism.

[0031] The enamel separation module includes a base 1, a rotary drive module 3, a rotating disk 4, a clamping module 5, and a grinding separation module 6. A support frame 2 is fixedly mounted on the base 1. The rotating disk 4 and the support frame 2 are rotatably connected. The rotary drive module 3 drives the rotating disk 4 to rotate. Several clamping modules 5 are fixedly mounted on the rotating disk 4 to clamp teeth 10. The grinding separation module 6 is fixedly connected to the support frame 2, and the enamel is separated from the teeth 10 through the grinding separation module 6. An enamel grinding mechanism 7 grinds the separated enamel; a digestion mechanism microwaves the detached enamel.

[0032] Because the enamel separation mechanism is equipped with a grinding separation module 6, the enamel on the tooth 10 is directly ground off. When the enamel is peeled off, it is in the form of small particles or powder, which is convenient for the subsequent enamel grinding mechanism 7 to grind it. After grinding, the enamel becomes finer, and the dissolution effect is better and more complete. Enamel peeling does not require cutting the tooth 10, and the whole process can be automated, which is highly efficient.

[0033] In this embodiment, please refer to Figures 1-6 A plurality of clamping modules 5 are arranged in a ring on the rotating seat. Each clamping module 5 includes a rotating seat 501 and an automatic gripper 502. The automatic gripper 502 is rotatably mounted on the rotating seat 501, which is fixedly mounted on the rotating disk 4. The automatic gripper 502 clamps the tooth 10, and the rotating seat 501 can drive the automatic gripper 502 to rotate. During the enamel grinding process, the grinding head grinds the surface of the tooth 10, and the tooth 10 rotates slowly, so that the entire annular surface of the tooth 10 can be ground uniformly.

[0034] In this embodiment, please refer to Figure 3 and Figure 4The grinding separation module 6 includes a telescopic component 601, an execution arm 602, a grinding motor 603, a grinding head 604, a camera, and a collection cover 605. The telescopic component 601 and the support frame 2 are fixedly connected. The execution arm 602 is installed at the telescopic end of the telescopic component 601. The grinding head 604 is rotatably mounted at the end of the execution arm 602. The execution arm 602 is a multi-segment articulated arm, which can flexibly drive the grinding head 604 to move back and forth, and change the angle of the grinding head 604 relative to the tooth 10, so as to realize the grinding head 604 to grind the tooth 10 comprehensively. The motor and the actuator arm 602 are fixedly connected. The grinding motor 603 and the grinding head 604 are connected by transmission. The collection cover 605 is fixedly connected to the end of the mounting plate and the telescopic member 601. The collection cover 605 is provided with an operation hole 6057.

The camera is fixedly installed inside the collection cover 605. When the grinding head 604 is grinding the tooth 10, the collection cover 605 covers the entire tooth 10.

[0035] The grinding head 604 is rotated by the grinding motor 603. During the rotation of the grinding head 604, the enamel on the surface of the tooth 10 and in contact with the grinding head 604 is peeled off. The camera monitors the color change and layering of the tooth 10 surface to determine whether the enamel has been completely peeled off. The collection cover 605 is moved by the telescopic component 601. When the movable end of the telescopic component 601 extends, the collection cover 605 moves away from the tooth 10. When the telescopic component 601 retracts, the collection cover 605 moves closer to the tooth 10 and finally covers it. The collection cover 605 can prevent the peeled enamel from splashing. The enamel is collected along the collection cover 605 and discharged from the discharge port 6053. After the enamel peeling of the surface of one tooth 10 is completed, the collection cover 605 moves away and switches to the next tooth 10. At this time, the collection cover 605 moves closer again to cover the tooth 10, and the grinding head 604 performs enamel peeling on the newly replaced tooth 10. The process is automatic switching and enamel peeling. High efficiency in enamel removal.

[0036] In this embodiment, please refer to Figures 1-2The rotary drive module 3 includes a rotary motor 301, a gear 302, and an external gear ring 303. The rotary motor 301 is fixedly connected to the support frame 2. Both the gear 302 and the external gear ring 303 are rotatably connected to the support frame 2. The output shaft of the rotary motor 301 and the gear 302 are coaxially fixedly connected. The external gear ring 303 and the gear 302 mesh with each other. The external gear ring 303 is fixedly connected to the rotating disk 4. The rotary motor 301 drives the gear 302 to rotate, the gear 302 drives the external gear ring 303 to rotate, the external gear ring 303 drives the rotating disk 4 to rotate, and the rotating disk 4 drives the clamping modules 5 on it to rotate. Since multiple clamping modules 5 are provided, multiple teeth 10 can be clamped sequentially. The rotation of the rotating disk 4 realizes the switching of teeth 10, ensuring the continuity of enamel peeling and improving efficiency.

[0037] In this embodiment, please refer to Figures 1-3 The enamel polishing mechanism 7 includes a linear guide rail 701, a slider 702, and a micro polisher 703.

[0038] Because it is equipped with a micro grinder 703, it can grind the enamel discharged from the outlet 6053, so that the size of the enamel dust particles reaches the required size, which is more efficient than manual grinding.

[0039] In this embodiment, please refer to Figure 1 , Figure 5 and Figure 6 The collection hood 605 includes a cylindrical section 6051, a conical section 6052, a hood tube 6054, and an air outlet 6058. The discharge port 6053 is located at the tip of the conical section 6052, and the operating hole 6057 is located in the cylindrical section 6051. The cylindrical section 6051 and the conical section 6052 are coaxially and fixedly connected. The hood tube 6054 is connected to the cylindrical section 6051. When an air blowing pipe 6055 is connected to the cylindrical section 6051, the air blowing pipe 6055 and the cylindrical section 6051 are tangentially connected. The air outlet 6058 is coaxial with the cylindrical section 6051 and extends into the cylindrical section 6051. A filter screen is provided at the end of the air outlet 6058.

The air blown out by the blower 6055 blows away the dust particles ground off the surface of the tooth 10 and makes them rotate along the cylinder wall of the cylindrical section 6051. Under the action of centrifugal force, the enamel dust particles adhere tightly to the cylinder wall and move downward under the action of gravity, and are finally discharged from the discharge port 6053. The cyclone inside the cylinder is discharged from the exhaust port. The surface of the tooth 10 is kept clean at all times to facilitate monitoring of the enamel peeling process, while avoiding enamel dust residue on the equipment and ensuring that the enamel dust quickly accumulates at the discharge port 6053.

[0041] In this embodiment, the enamel digestion mechanism includes a digestion vessel and a digestion apparatus. The digestion vessel is used to hold the enamel powder after it has been ground by the enamel grinding mechanism 7, and the digestion apparatus is used to digest the enamel powder. After the ground enamel and chemical solvent have fully combined, they are digested in the digestion apparatus, so that the boron element in the enamel is completely dissolved in the solution, so that the boron element can be enriched, collected and measured subsequently.

[0042] An embodiment of a tooth sample digestion method provided by the present invention includes the following steps:

[0043] Enamel separation steps: The tooth 10 is clamped on the automatic gripper 502. The rotary drive module 3 drives the clamped tooth 10 to rotate to the designated position. The collection cover 605 covers the automatic gripper 502 and the tooth 10. The actuator arm 602 controls the grinding head 604 to grind the tooth 10 and remove the enamel. The rotating seat 501 rotates slowly during the grinding process so that the grinding head 604 can completely remove the enamel from the surface of the tooth 10. The grinding process of the tooth 10 is monitored by a camera. When the color of the tooth 10 changes to light yellow, it proves that the enamel on the surface of the tooth 10 has been cleaned. The actuator arm 602 drives the grinding head 604 to move other parts of the tooth 10 to continue grinding.

[0044] Enamel grinding steps: The ground enamel is collected by the collection cover 605 and enters the micro grinder 703 through the discharge port 6053 of the collection cover 605. The micro grinder 703 grinds the enamel to 200 mesh. When the enamel on a tooth 10 is completely removed, the telescopic component 601 moves the collection cover 605 away from the automatic gripper 502. The rotary drive module 3 drives the next set of teeth 10 to enter the designated position. The telescopic component 601 moves the collection cover 605 to cover the automatic gripper 502 again. During the movement of the collection cover 605, the slider 702 drives the micro grinder 703 to move synchronously.

[0045] Digestion steps: Weigh the ground enamel and put it into a digestion vessel. Add a certain amount of nitric acid solution and hydrogen peroxide solution. For every 50 mg of enamel, add 3 ml of 50% nitric acid and 2 ml of 30% hydrogen peroxide and shake. Place the mixed solution into a digestion apparatus for microwave digestion.

[0046] Compared to the traditional tooth sample digestion process, this method improves the efficiency of enamel separation and enamel grinding, thereby increasing experimental efficiency.
