Description

Technical Field

[0001] The present invention relates to the technical field of medical appliances, and particularly to a tooth repair positioning device for stomatology. Background Technique

[0002] Tooth repair is a method of repairing tooth defects with artificial substances. The substances used for repair are called filling materials. Anyone with tooth tissue defects caused by dental caries, wedge-shaped defects, trauma, etc. needs to be repaired to restore its shape and function. When the lesion has spread to the dental pulp and even caused periapical disease, the dental pulp should be treated first and then the tooth should be filled. Currently, during tooth repair, it is mostly necessary for the patient to keep their mouth open for a long time. During this process, when the patient is tired, the mouth is likely to close, which will affect the dentist's operation.

[0003] Combining the above problems, we will find that the existing tooth repair positioning devices on the market are very difficult to avoid the above-mentioned problems simultaneously when in use, and even if they can be solved, they need to be solved by cooperating with external tools, thus unable to achieve the desired effect.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Embodiment 1: Please refer to Figures 1 - 8 , the present invention provides a technical solution: A tooth repair positioning device for oral medicine, including a handheld component 1, a self-locking component 2 is fixedly arranged at the side end of the handheld component 1, an expansion component 3 is fixedly arranged on the surface of the handheld component 1, a stabilizing component 5 is rotatably arranged on the surface of the handheld component 1, and the expansion component 3 is rotatably arranged inside the stabilizing component 5;

[0035] The handheld component 1 includes a connecting piece 13, and two expansion arms 14 are rotatably connected to the surface of the connecting piece 13. Sliding grooves are provided at the proximal ends of the two expansion arms 14 close to each other;

[0036] The stabilizing component 5 includes a hollow plate 51. A driving hole and two transmission holes are provided on the surface of the hollow plate 51. The expansion component 3 includes a screw rod A 31, and the screw rod A 31 is rotatably connected in the driving hole. A motor 36 is fixedly connected to the surface of the connecting piece 13. The end of the screw rod A 31 is fixedly connected to the output end of the motor 36. A driving gear B 34 is fixedly connected to the surface of the screw rod A 31, and the driving gear B 34 is rotatably connected in the hollow plate 51. Two driving gears A 32 are rotatably connected in the hollow plate 51, and both of the two driving gears A 32 are meshed with the driving gear B 34. One end of the active telescopic member 33 is fixedly connected to the active telescopic member 33, and the telescopic end of the active telescopic member 33 is fixedly connected to a transmission gear 37. The screw rod A 31 is threadedly connected to a moving box 39. The screw rod A 31 penetrates through one side end of the moving box 39, and the transmission gear 37 is rotatably connected in the moving box 39. An extrusion member 38 is slidably connected in the moving box 39. The transmission gear 37 and the extrusion member 38 are meshed, and the extrusion member 38 is slidably connected in the sliding groove.

[0037] Specifically, when supporting a patient's oral cavity, the two expansion arms 14 can be first placed inside the patient's oral cavity, and then the motor 36 can be started to drive the rotation of the screw rod A 31, thereby driving the driving gear B 34 to rotate together. Since both the driving gear A 32 and the driving gear B 34 are rotatably arranged on the inner wall of the hollow plate 51, when the driving gear B 34 rotates, it can drive the driving gear A 32 to rotate. When the driving gear A 32 rotates, it will drive the active telescopic member 33 to rotate together. Since the moving box 39 is threadedly arranged on the surface of the screw rod A 31, when the screw rod A 31 rotates, it can drive the moving box 39 to move left and right. And because the active telescopic member 33 is connected to the transmission gear 37, when the active telescopic member 33 rotates, it can drive the transmission gear 37 to rotate together. And because the transmission gear 37 and the extrusion member 38 are meshed, when the transmission gear 37 rotates, it will drive the extrusion member 38 to move up and down. Since there are two transmission gears 37 and extrusion members 38, and they are symmetrically arranged, when the two extrusion members 38 move up and down respectively, they can push the two expansion arms 14 to expand. And because the extrusion member 38 is slidably arranged in the moving box 39, when the moving box 39 moves, it will drive the extrusion member 38 to move together. At this time, the extrusion member 38 will continuously push up the expansion arm 14, thereby enabling the two expansion arms 14 to expand, and further expanding the patient's oral cavity. Since the moving box 39 will drive the transmission gear 37 to move together when it moves, the active telescopic member 33 can be set as a telescopic structure, so that during the movement of the transmission gear 37, the transmission gear 37 can still be driven to rotate by the active telescopic member 33.

[0038] As a further limitation of the expansion component 3 of the present invention, the expansion component 3 further includes a mounting box 35. The mounting box 35 is fixedly connected to the surface of the connecting member 13, and the mounting box 35 is rotatably sleeved on the surface of the A screw rod 31. The motor 36 is disposed in the mounting box 35. The pressing member 38 includes a lifting portion 381 and a pressing portion 382. The lifting portion 381 is engaged with the transmission gear 37. The pressing portion 382 is fixedly connected to the end of the lifting portion 381. The pressing portion 382 is slidably connected in the sliding groove.

[0039] Specifically, since the motor 36 is disposed at the end of the A screw rod 31, in order to prevent the patient's saliva from falling onto the motor 36 along the A screw rod 31 during use, thereby damaging the motor 36, an installation box 35 can be sleeved on the motor 36. By passing the output end of the motor 36 through the installation box 35 and fixedly connecting the installation box 35 to the handheld member 11, the motor 36 can be stably disposed and operate stably during the installation. During use, in order to enable the pressing member 38 to lift the expansion arm 14 and the pressing member 38 to always press the inner wall of the sliding groove during sliding in the sliding groove, the pressing member 38 can be set into two parts. The pressing portion 382 is disposed at the end of the lifting portion 381. The lifting portion 381 is engaged with the transmission gear 37, so as to perform lifting. The pressing portion 382 is slidably disposed in the sliding groove, and the end of the pressing portion 382 is provided with an inclined surface structure, so that the pressing portion 382 can always press the inner wall of the sliding groove during sliding, and then the expansion arm 14 can be pushed to expand.

[0040] As a further limitation of the stability component 5 of the present invention, the stability component 5 further includes an insertion plate 52, a sliding plate 53 and a rotating shaft 54. The insertion plate 52 is fixedly connected to one end of the hollow plate 51. The insertion plate 52 is rotatably connected to the surface of the A screw rod 31. The sliding plate 53 is slidably connected in the insertion plate 52. The rotating shaft 54 is fixedly connected to the end of the sliding plate 53. The rotating shaft 54 is rotatably connected in the sliding groove.

[0041] Specifically, during use, to enable the stable setting of the A lead screw 31 and to ensure that the insertion plate 52 can maintain a stable vertical state after the two expansion arms 14 are expanded, thereby enabling the stable setting of the A lead screw 31, a sliding plate 53 can be slidably arranged within the insertion plate 52, and a rotating shaft 54 can be fixedly arranged at the end of the sliding plate 53. The rotating shaft 54 is rotatably arranged within the sliding groove. By providing two sliding plates 53 and the rotating shaft 54, when the two expansion arms 14 are expanded, the sliding plate 53 will move up and down accordingly, thereby enabling the insertion plate 52 to always maintain its position unchanged, and further enabling the stable setting of the A lead screw 31. Also, during use, to prevent the patient's saliva from dripping between the A drive gear 32 and the active telescopic member 33, thereby affecting their meshing, the hollow plate 51 can be fixedly arranged on the insertion plate 52, and there is a gap inside the hollow plate 51 for the rotation of the A drive gear 32 and the B drive gear 34.

[0042] As a further limitation of the handheld assembly 1 of the present invention, the handheld assembly 1 further includes a handheld member 11 and control buttons 12. The handheld member 11 is fixedly connected to the inside of the connecting member 13, and multiple control buttons 12 are provided, and all the multiple control buttons 12 are fixedly connected to the surface of the handheld member 11.

[0043] Specifically, during use, to facilitate the doctor's holding, the handheld member 11 can be arranged on the connecting member 13. At this time, the doctor can hold the handheld member 11 to stably arrange the handheld assembly 1. Also, to facilitate the subsequent control of the operation of the A electric telescopic rod 27, the motor 36, and the B electric telescopic rod 82, multiple control buttons 12 are arranged on the handheld member 11. By electrically connecting the control buttons 12 to the A electric telescopic rod 27, the motor 36, and the B electric telescopic rod 82, the operation of the three can still be controlled through the control buttons 12, thereby facilitating the subsequent tooth repair operation by the doctor.

[0044] As a further limitation of the self-locking assembly 2 of the present invention, the self-locking assembly 2 includes an A fixing member 21, a B fixing member 22, an A rotating member 23, a B rotating member 24, an A engaging tooth 25, and a B engaging tooth 26. Installation grooves are respectively formed on the surfaces of the two expansion arms 14, and the A fixing member 21 and the B fixing member 22 are respectively fixedly connected to the two installation grooves. The A rotating member 23 and the B rotating member 24 are respectively rotatably connected to the surfaces of the A fixing member 21 and the B fixing member 22. Two B engaging teeth 26 are provided, and the two B engaging teeth 26 are symmetrically arranged. Both of the two B engaging teeth 26 are slidably connected to the lower end of the A rotating member 23. Two A engaging teeth 25 are provided, and the two A engaging teeth 25 are symmetrically arranged. Both of the two A engaging teeth 25 are fixedly connected to the inside of the B rotating member 24, and the two A engaging teeth 25 and the B engaging teeth 26 are engaged with each other.

[0045] Specifically, after the two expansion arms 14 are expanded, it is necessary to fix the positions of the expansion arms 14 at this time, so that the patient's oral cavity can maintain the existing opening size, which is convenient for subsequent repair operations by the doctor. At this time, the A engaging teeth 25 and the B engaging teeth 26 can be engaged with each other, so that the expansion size between the two expansion arms 14 can be fixed. By fixedly arranging the A engaging teeth 25 inside the B rotating member 24, slidingly arranging the B engaging teeth 26 at the lower end of the A rotating member 23, inserting the B engaging teeth 26 into the B rotating member 24, and engaging the A engaging teeth 25 and the B engaging teeth 26, the positions between the A rotating member 23 and the B rotating member 24 can be fixed. Since the A rotating member 23 is rotatably arranged on the A fixing member 21, and the B rotating member 24 is rotatably arranged on the B rotating member 24, and the A fixing member 21 and the B fixing member 22 are respectively arranged on the two expansion arms 14, after the positions between the A rotating member 23 and the B rotating member 24 are fixed, the positions of the two expansion arms 14 can be relatively fixed, thus avoiding the closing of the two expansion arms 14 due to the patient's biting during the repair operation, which affects the repair work.

[0046] The specific implementation manner of this embodiment is as follows: When expanding the patient's oral cavity, the motor 36 can be started to drive the two expansion arms 14 to expand. The expansion arms 14 can be arranged inside the patient's oral cavity in advance, and the expansion of the expansion arms 14 can drive the patient's oral cavity to expand, which is convenient for subsequent observation by the doctor and subsequent repair operations. After the expansion is completed, it is necessary to fix the positions of the expansion arms 14 at this time. Since a plurality of triangular engaging teeth are arranged on the surfaces of the A engaging teeth 25 and the B engaging teeth 26, and the engaging teeth of the two are symmetrically arranged, the A engaging teeth 25 and the B engaging teeth 26 can be engaged with each other. During the engagement, they cannot move up and down. Through the engagement of the A engaging teeth 25 and the B engaging teeth 26, the positions between the two expansion arms 14 can be relatively fixed, so that the patient's oral cavity will not close during the repair operation, thus avoiding affecting the repair operation. When it is necessary to release the engagement between the two, the A electric control telescopic rod 27 can be controlled to contract, so that the two B engaging teeth 26 can move closer to each other, and thus the A engaging teeth 25 and the B engaging teeth 26 can be separated. At this time, they are no longer engaged with each other, and the distance position between the A rotating member 23 and the B rotating member 24 can be changed.

[0047] Embodiment 2: Please refer to Figures 1 - 8, the present invention provides a technical solution: an observation component 4 is fixedly arranged at the side end of the expansion component 3. The observation component 4 includes a mounting plate 41, an A adjusting member 42, a B lead screw 43, a B adjusting member 44 and an oral mirror 45. There are two mounting plates 41, and both of the two mounting plates 41 are fixedly connected to one end of the moving box 39. The A adjusting member 42 is rotatably connected between the two mounting plates 41. The B adjusting member 44 is rotatably connected to one end of the A adjusting member 42. An A threaded hole is formed on the surface of the A adjusting member 42. The B lead screw 43 penetrates through the surface of the B adjusting member 44 and is threadedly arranged in the A threaded hole.

[0048] Specifically, after expanding the patient's oral cavity, in order to be able to observe the diseased tooth area inside the patient's oral cavity, and during the observation, the doctor does not need to hold the oral mirror 45 by hand. Therefore, the mounting plate 41 can be arranged on the moving box 39, and the A adjusting member 42 is rotatably arranged on the mounting plate 41, the B adjusting member 44 is rotatably arranged on the A adjusting member 42, and by tightening the B lead screw 43, the deflection angle of the B adjusting member 44 can be fixed, so that the deflection angle of the oral mirror 45 can be adjusted arbitrarily. Furthermore, the diseased tooth area inside the patient's oral cavity can be clearly observed through the oral mirror 45, and the doctor does not need to hold the oral mirror 45 during the observation, thus liberating one hand of the doctor, so that the doctor can perform efficient repair operations.

[0049] As a further limitation of the observation component 4 of the present invention, there are two observation components 4, and the two observation components 4 are symmetrically arranged, and both of the two observation components 4 are fixedly arranged on the moving box 39.

[0050] Specifically, in order to be able to observe both sides of the moving box 39 simultaneously, the observation component 4 is set to two, and the two observation components 4 are symmetrically arranged on the moving box 39, and the two observation components 4 can be adjusted separately, which is convenient for the doctor to observe multiple diseased teeth simultaneously.

[0051] The specific implementation manner of this embodiment is: during the repair operation, in order to enable the doctor to observe the diseased tooth area more conveniently and clearly, two observation components 4 can be arranged on the moving box 39. By adjusting the deflection angle of the oral mirror 45, the doctor can observe the details of the diseased tooth area in real time, and the doctor does not need to hold the oral mirror 45, thus liberating one hand of the doctor, so that the repair operation can be carried out more efficiently.

[0052] Embodiment 3: Please refer to Figures 1 - 8, the present invention provides a technical solution: an adjustment component 6 is rotatably arranged on the surface of the handheld component 1, a limiting component 8 is slidably arranged at one end of the adjustment component 6, a positioning component 7 is fixedly arranged at one end of the adjustment component 6, the positioning component 7 is rotatably arranged on the handheld component 1, there are two adjustment components 6, positioning components 7 and limiting components 8, and they are all symmetrically arranged. The adjustment component 6 includes an expansion block 61, a central block 62, a C screw rod 63, a follower telescopic member 64 and an extension rod 65. The expansion block 61 is fixedly connected to the surface of the connecting member 13, the central block 62 is rotatably connected to the upper end of the expansion block 61, the follower telescopic member 64 is fixedly connected inside the central block 62, the extension rod 65 is fixedly connected to the telescopic end of the follower telescopic member 64. A B threaded hole is opened at the upper end of the expansion block 61, and the C screw rod 63 penetrates through the surface of the central block 62 and is threadedly arranged in the B threaded hole.

[0053] Specifically, when positioning the diseased tooth of the patient, the expansion block 61 can be fixed on the connecting member 13, the central block 62 is rotatably arranged on the expansion block 61, the follower telescopic member 64 is fixedly arranged on the central block 62, and the extension rod 65 is fixedly arranged at the telescopic end of the follower telescopic member 64. At this time, by rotating the central block 62, the follower telescopic member 64 and the extension rod 65 can be driven to rotate, and then the positioning component 7 can be driven to move to the diseased tooth. When the positioning component 7 moves to the diseased tooth, the C screw rod 63 can be tightened, so that the central block 62 cannot rotate at this time, and thus the position of the positioning component 7 can be fixed.

[0054] As a further limitation of the positioning component 7 of the present invention, the adjustment component 6 further includes a universal joint 66. The positioning component 7 includes a building plate 71, an intermediate arm 72, a positioning plate 73, a bidirectional screw rod 74 and an arc-shaped member 75. The arc-shaped member 75 includes an arc portion 751 and a rotating portion 752. A rotating groove is opened at the end of the expansion arm 14. The arc portion 751 is fixedly connected to the upper end of the rotating portion 752. There are two building plates 71, and both building plates 71 are slidably connected to the surface of the arc portion 751. The rotating portion 752 is rotatably connected to the surface of the expansion arm 14. There are multiple intermediate arms 72, and multiple intermediate arms 72 are all fixedly connected between the two building plates 71. A limiting groove is opened on the surface of the building plate 71. The positioning plate 73 is slidably connected in the limiting groove. The bidirectional screw rod 74 penetrates through the inner wall of the limiting groove, and both positioning plates 73 are threadedly connected to the surface of the bidirectional screw rod 74. The universal joint 66 is fixedly connected between the extension rod 65 and the bidirectional screw rod 74.

[0055] Specifically, when positioning the diseased tooth, the bidirectional screw 74 can be rotated to drive the two positioning plates 73 to move, so that the diseased tooth can be clamped by the two positioning plates 73, and the positioning is completed at this time. In order to stably arrange the positioning plate 73, a limiting groove is opened on the erection plate 71, and the positioning plate 73 is arranged in the limiting groove. The two erection plates 71 can be fixed by the middle arm 72. The two erection plates 71 are placed on the healthy teeth on both sides of the diseased tooth. At this time, the diseased tooth can be clamped by moving the positioning plate 73, and then accurate positioning can be achieved. When rotating the bidirectional screw 74, the universal joint 66 can be arranged between the extension rod 65 and the bidirectional screw 74. At this time, the bidirectional screw 74 can be driven to rotate together by rotating the follow-up telescopic member 64, so as to position the diseased tooth. In order to enable the erection plate 71 to slide stably in the patient's oral cavity, the erection plate 71 can be slidably arranged on the arc portion 751, so that the erection plate 71 can move along the approximate arc of the patient's oral teeth.

[0056] As a further limitation of the limiting component 8 of the present invention, the limiting component 8 includes a limiting block 81 and a B electric control telescopic rod 82. There are two limiting blocks 81, and both of the two limiting blocks 81 are slidably connected to one end of the central block 62. The B electric control telescopic rod 82 is fixedly connected between the two limiting blocks 81.

[0057] Specifically, after the positioning of the diseased tooth is completed, the B electric control telescopic rod 82 can be contracted at this time, so as to control the two limiting blocks 81 to slide. Through the clamping of the two limiting blocks 81, the follow-up telescopic member 64 cannot rotate at this time, and then the diseased tooth can be stably positioned.

[0058] The specific implementation manner of this embodiment is as follows: When positioning the diseased tooth, the doctor can first manually rotate the central block 62 to drive the erection plate 71 to move in the patient's oral cavity. When the erection plate 71 moves to the diseased tooth, the follow-up telescopic member 64 can be rotated to drive the positioning plate 73 to clamp the diseased tooth, and the diseased tooth can be positioned. Through the positioning of the diseased tooth by the positioning plate 73, it is convenient for the doctor to observe more conveniently during the subsequent tooth repair, so as to facilitate the subsequent repair operation.
