Description

Technical Field

[0001] The present invention belongs to the technical field of oral orthodontics, and in particular relates to an intra-oral observation device for orthodontic treatment. Background Art

[0002] Orthodontics generally refers to tooth correction, which usually refers to the treatment process of correcting uneven tooth alignment, abnormal tooth shape, and abnormal tooth color through oral technical means. There are many methods of tooth correction, such as resin veneers, porcelain veneers, porcelain teeth, orthodontics, etc. The treatment method should be selected based on the actual situation of the individual's teeth, the type of malocclusion, etc., and then comprehensively considered according to personal requirements.

[0003] During orthodontic treatment, a comprehensive and detailed examination of the patient's oral cavity is required, which requires the use of intraoral observation equipment. For example, a user-friendly oral observation device, such as that disclosed in Application No. CN202321260967.4, utilizes a servo drive motor and a belt. The servo drive motor drives a rotating disk to move the belt. The movement of the belt, in turn, drives the camera housing to rotate by friction, changing the orientation of the camera housing and thus facilitating the change of the camera angle, allowing for comprehensive observation and diagnosis of the interior of the oral cavity.

[0004] However, in practice, the camera housing rotation mechanism, which relies on belt friction to drive it, often suffers from suboptimal adjustment accuracy. While this rotation method, which relies on physical friction, can offer certain conveniences in certain situations, it has significant limitations in terms of precise control. The instability of friction can cause uneven movement of the camera housing during rotation, affecting the accuracy and stability of the shooting angle. Furthermore, over time, the belt may lose its original friction due to wear, further reducing adjustment accuracy and even causing the device to malfunction.

[0005] Furthermore, when the camera housing is inserted deep into the mouth, it is susceptible to contamination by saliva, which will negatively impact the clarity of the footage. When cleaning is necessary, the camera must be removed from the mouth. During the cleaning process, the camera comes into contact with the outside air and is susceptible to absorbing airborne particles.

[0006] In addition, if the patient has a dry heave reaction, the tongue will naturally curl up. If the camera is continued to be operated at this time, it will not only aggravate the patient's dry heave feeling and reduce his comfort, but also in the process of the motor forcibly driving the camera housing to rotate, the patient's tongue in the dry heave state may come into contact with the camera housing, causing damage to the tongue tissue during the rotation process. Summary of the Invention

[0007] The purpose of the present invention is to provide an intraoral observation device for orthodontic treatment, which can achieve efficient and accurate observation of the interior of the oral cavity, while meeting the cleanliness and defogging requirements during use and ensuring the safety and comfort of the patient.

[0021] In a preferred embodiment, the lighting lamps are arranged in a ring array around the camera.

[0022] The technical effects achieved by the present invention are:

[0023] This invention replaces the traditional method of relying on belt friction to drive camera rotation by adopting a mechanical traction rope combined with a compression spring design. This method not only avoids the uneven movement caused by the instability of physical friction, but also enables more precise and stable adjustment of the shooting angle. Doctors can flexibly control the camera angle according to actual needs, ensuring a comprehensive and detailed observation of the internal structures of the oral cavity, thereby improving the accuracy of diagnosis. In addition, this design eliminates the risk of equipment failure caused by belt wear in traditional methods, thereby extending the service life of the equipment.

[0024] This invention incorporates an automatic defogger function, using hot air to remove fog from the protective cover. The absorbent cotton pads absorb moisture from the air, ensuring that the air entering the protective cover remains dry, effectively preventing blurry images caused by fogging on the protective cover surface. Furthermore, as the protective cover rotates, its outer surface contacts the end of the outer shell, scraping away saliva, achieving an automatic cleaning effect and further improving image quality. This not only helps maintain device hygiene but also reduces the impact of external contamination on image clarity, allowing doctors to obtain clearer and more accurate images of the interior of the oral cavity.

[0025] This invention features a unique locking mechanism. When a patient retches, the tongue naturally pushes against the tongue depressor, compressing the air in the spring-loaded airbag. This triggers the locking element to engage the slot at the lower end of the movable rod, restricting the camera's rotation. This prevents continued camera operation from exacerbating patient discomfort or damaging tongue tissue. This safety mechanism significantly improves patient comfort and security during the examination without affecting normal use. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing the embodiments of the present invention, cross-sectional views illustrating device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, the three-dimensional dimensions of length, width, and depth should be included.

[0049] Please see the attached Figure 1 、 Figure 2 、 Figure 3 and Figure 8 As shown, this embodiment provides an intraoral observation device for orthodontic treatment, comprising a housing 1, a collar 2 rotatably connected to the housing 1, a support plate 3 fixedly connected to one side of the collar 2, and a tongue depressor 5 rotatably connected to the lower support plate 3;

[0050] A photographing mechanism 4 is rotatably connected to one end of the housing 1 and is used to photograph the interior of the oral cavity;

[0051] An adjusting mechanism 6 is slidably connected to the interior of the housing 1 and is used to adjust the shooting angle of the shooting mechanism 4;

[0052] The demisting mechanism 7 includes an internal gas generating portion 71 provided in the housing 1 , and a heating portion 72 is provided at one end of the gas generating portion 71 for heating the incoming air;

[0053] The fixing mechanism 8 includes an air delivery portion 81 disposed at one end of the housing 1 and a locking portion 82 disposed inside the housing 1 .

[0054] In this embodiment, the data cable is inserted into the right interface of the housing 1, and the other end is connected to an external device. The signal is transmitted through the data cable, and the internal conditions of the oral cavity are displayed on the external device in real time.

[0055] When in use, the camera end of the housing 1 is placed in the oral cavity, the patient's teeth bite the support plate 3, the support plate 3 is used to open the oral cavity, and the tongue depressor 5 presses the patient's tongue to facilitate observation of the internal conditions of the oral cavity.

[0056] It should be noted that the tongue depressor 5 is rotatably mounted on the support plate 3 and a torsion spring (not shown) is mounted on the rotating shaft of the tongue depressor 5. The torsion spring enables the tongue depressor 5 to return to its original position after being turned over.

[0057] Next, please refer to Figure 9 and Figure 10 The shooting mechanism 4 includes an arc-shaped slide groove 401, which is opened on the inner wall of the shell 1. A slider 402 is slidably connected inside the arc-shaped slide groove 401. Both ends of the slider 402 are fixedly connected to metal springs 403, and the other end of the metal spring 403 is fixedly connected to the inner wall of the arc-shaped slide groove 401. A protective cover 404 is fixedly connected to the slider 402, and a mounting block 405 is fixedly connected inside the protective cover 404. The mounting block 405 is installed with cameras 406 and lighting lamps 407 in an array.

[0058] In this embodiment, camera 406 is used to capture the interior of the oral cavity, while lights 407 provide the necessary light source to ensure effective illumination. Lights 407 are arranged in a circular array around camera 406 to ensure uniform illumination of the oral cavity. Camera 406 utilizes a high-definition micro-lens, capturing clear images and facilitating detailed diagnosis by the physician.

[0059] Secondly, please also refer to Figure 3 and Figure 7 The adjusting mechanism 6 includes a guide block 601, which is fixedly connected to the inner wall of the outer shell 1. The guide block 601 is slidably connected to the moving rod 602. One end of the moving rod 602 is fixedly connected to a handle 603, and the outer shell 1 is also provided with a guide groove for the sliding of the handle 603. The other end of the moving rod 602 is fixedly connected to a traction rope 604, and the other end of the traction rope 604 is connected to the protective cover 404. The outer wall of the moving rod 602 is fixedly connected to a ring 605, and both sides of the ring 605 are fixedly connected to a first compression spring 606, and the other end of the first compression spring 606 is fixedly connected to the guide block 601. The bottom surface of the moving rod 602 is provided with a locking groove 607.

[0060] In this embodiment, when adjusting the angle of the camera 406, one's finger hooks one of the handles 603 and moves it to the right, driving the moving rod 602 and the traction rope 604 to move to the right, squeezing and stretching the first compression spring 606 thereon, causing the protective cover 404 to rotate, thereby adjusting the shooting angle; when the protective cover 404 rotates, the traction rope 604 pulls the other moving rod 602, squeezing and stretching the first compression spring 606 thereon; the rotation direction of the protective cover 404 is controlled by selecting which handle 603 to pull (the protective cover 404 rotates to the side of the handle 603 pulled to adjust the shooting angle); when the handle 603 is not pulled, the restoring force of the first compression spring 606 resets the moving rod 602;

[0061] The housing 1 is rotatably connected to the collar 2. After the patient bites the support plate 3 and fixes the collar 2, the housing 1 can be rotated along the collar 2 to further adjust the shooting angle.

[0062] As protective cover 404 rotates, slider 402 slides along arcuate groove 401, compressing metal spring 403. When there is no traction, metal spring 403 automatically resets protective cover 404 to its neutral position. Furthermore, as protective cover 404 rotates, it contacts the end of housing 1, which scrapes away saliva adhering to the outer surface of protective cover 404, automatically cleaning it and improving the transparency of protective cover 404, ensuring optimal photography. (Protective cover 404 is made of a transparent material.)

[0063] Next, please refer to Figure 3 and Figure 8 The gas producing part 71 includes a first hollow cylinder 711, which is fixedly connected to the inside of the outer shell 1. The first hollow cylinder 711 is provided with air holes 712 in a ring-shaped distribution. A movable rod 713 is inserted into one end of the first hollow cylinder 711, and one end of the movable rod 713 is fixedly connected to a first piston plate 714. The other end of the movable rod 713 is fixedly connected to a force block 716. One side of the first piston plate 714 is fixedly connected to a second compression spring 715, and the other end of the second compression spring 715 is fixedly connected to the inner wall of the first hollow cylinder 711. One end of the first hollow cylinder 711 is fixedly connected to a gas pipe 717.

[0064] Please refer again Figure 1 and Figure 8 The heating part 72 includes a copper tube 721, which is fixedly connected to the gas pipe 717. A heat-conducting column 722 is fixedly connected to the copper tube 721. A heat-absorbing block 723 is fixedly inlaid on the outer surface of the shell 1, and the heat-conducting column 722 is fixedly connected to the heat-absorbing block 723. The inner wall of the copper tube 721 is fixedly connected to a water-absorbing cotton board 724. The other end of the copper tube 721 is fixedly connected to an air guide tube 725, and the other end of the air guide tube 725 is connected to the shooting mechanism 4 (the air guide tube 725 is a retractable hose).

[0065] In this embodiment, when the moving rod 602 is pulled, the other moving rod 602 moves in the opposite direction, and the moving rod 602 moving in the opposite direction pushes the force block 716 to move to the left. The force block 716 moves to the left, driving the movable rod 713 and the first piston plate 714 to move the compressed air along the first hollow cylinder 711 and squeeze the second compression spring 715. The compressed air enters the copper tube 721 through the air supply pipe 717, pushing the preheated air in the copper tube 721 along the air guide pipe 725 into the protective cover 404, removing the fog on the inner surface of the protective cover 404.

[0066] A water-absorbing cotton board 724 is provided inside the copper tube 721 to absorb moisture in the air and increase the dryness of the gas entering the protective cover 404.

[0067] If only hot air needs to be introduced into the protective cover 404, the handle 603 or both handles 603 are pulled to the left at the same time, causing the first piston plate 714 to move to the left to compress the air in the first hollow cylinder 711; when the force block 716 has no resistance, the reset force of the second compression spring 715 causes the first piston plate 714 to automatically reset; in addition, air holes 712 are evenly distributed on the first hollow cylinder 711 to facilitate air circulation and facilitate exhaust and air intake.

[0068] After the shooting end of the housing 1 is placed in the oral cavity, the heat absorbing block 723 absorbs the heat in the oral cavity and transfers it to the copper tube 721 through the heat conducting column 722, preheating the air in the copper tube 721 for subsequent demisting work.

[0069] Please refer again Figure 3 and Figure 4 The air delivery part 81 includes an annular air storage groove 811, which is opened on the outer surface of the shell 1. The outer side of the annular air storage groove 811 is rotatably connected to an annular sealing cover 812. A spring air bag 813 is installed on the lower support plate 3 using a support plate. The spring air bag 813 is connected to a first air inlet pipe 814, and the other end of the first air inlet pipe 814 is connected to the annular sealing cover 812.

[0070] In this embodiment, the annular sealing cover 812 is rotatably connected to the outside of the annular gas storage groove 811, ensuring that the annular sealing cover 812 does not rotate during the rotation of the housing 1. Specifically, the spring airbag 813 is fixedly connected to the support plate 3 via a support plate. Once the support plate 3 is engaged by the patient, it cannot rotate. Furthermore, the first air inlet pipe 814 between the annular sealing cover 812 and the spring airbag 813 is made of a hard material. This pipe not only connects the two but also serves to limit the rotation of the annular sealing cover 812, thereby ensuring the stability of the gas delivery process.

[0071] Please refer again Figure 5 and Figure 6The locking portion 82 includes a second hollow cylinder 821, which is fixedly connected to the bottom surface of the inner cavity of the outer shell 1. A second air inlet pipe 822 is connected to the second hollow cylinder 821, and the other end of the second air inlet pipe 822 is connected to the annular air storage groove 811. A lifting rod 823 is inserted into the upper end of the second hollow cylinder 821, and one end of the lifting rod 823 is fixedly connected to the second piston plate 824, and the other end of the lifting rod 823 is fixedly connected to the locking member 826. The outer portion of the lifting rod 823 is provided with a third compression spring 825.

[0072] In this embodiment, during the filming process, if the patient feels uncomfortable and retches, the tongue naturally pushes up against the tongue depressor 5, and the tongue depressor 5 compresses the air in the spring airbag 813. The compressed air enters the annular air storage groove 811 along the first air inlet pipe 814, and then enters the second hollow cylinder 821 along the second air inlet pipe 822, pushing the second piston plate 824 to move upward. The upward movement of the second piston plate 824 drives the lifting rod 823 and the locking member 826 to move upward, and the locking member 826 is stuck in the locking groove 607 at the lower end of the moving rod 602. At this time, the moving rod 602 cannot move, thereby preventing the rotation of the filming mechanism 4 and friction with the tongue from causing aggravated retching, thereby improving the patient's comfort.

[0073] Please refer again Figure 6 The lock 826 includes a fixed seat 8261, which is fixedly connected to the lifting rod 823. Two locking blocks 8262 are slidably connected inside the fixed seat 8261. One side of the locking block 8262 is fixedly connected to a fourth compression spring 8263, and the other end of the fourth compression spring 8263 is fixedly connected to the inner wall of the fixed seat 8261. A tension spring 8264 is also fixedly connected between the two locking blocks 8262.

[0074] In this embodiment, the locking block 8262 on the locking member 826 is slightly movable on the fixing seat 8261, facilitating insertion into the locking slot 607 when misaligned. The fourth compression spring 8263 and tension spring 8264 function to reset the locking block 8262. When the patient's tongue no longer pushes up against the tongue depressor 5, the tongue depressor 5 returns to its original position, the spring airbag 813 is no longer squeezed and returns to its original shape. The air pressure within the second hollow cylinder 821 decreases, and the second piston plate 824 returns to its original position under the reset force of the third compression spring 825. The locking block 8262 disengages the locking slot 607, freeing the movable rod 602 from its restraint position and allowing it to move.

[0075] The working principle of the present invention is:

[0076] Device placement and initial fixation:

[0077] Support and opening: When the device is placed in the mouth, the patient bites the support plate 3 to open and stabilize the oral space. At the same time, the tongue depressor 5 uses the torsion spring characteristics installed thereon to press the tongue, ensuring that the inside of the mouth is fully exposed for easy observation.

[0078] Shooting preparation and angle adjustment:

[0079] The photographing mechanism 4 includes a camera 406 and lighting lamps 407. The lighting lamps 407 are arranged in a circular array around the camera 406 to ensure uniform illumination inside the oral cavity. The camera 406 uses a high-definition micro lens to capture clear images.

[0080] Adjustment Mechanism 6: To adjust the imaging angle, the doctor pulls handle 603 to slide the movable rod 602 along the guide block 601, which in turn rotates the protective cover 404 and internal components via the traction rope 604. A first compression spring 606 provides a reset force, allowing the protective cover 404 to automatically return to its neutral position in the absence of external forces. Furthermore, the housing 1 can rotate relative to the collar 2, further enhancing the possibilities for angle adjustment.

[0081] Automatic cleaning and demisting mechanism:

[0082] The demisting mechanism 7 consists of an air-generating section 71 and a heating section 72. The air-generating section 71 includes a piston system that compresses air when the movable rod 602 moves in the opposite direction and delivers it to the copper tube 721 through the air pipe 717 for preheating. The heating section 72 utilizes a heat-absorbing block 723 to absorb heat from the oral cavity and transfers it to the copper tube 721 through the heat-conducting column 722, preheating the air therein. Ultimately, the dry, warm air enters the protective cover 404 through the air pipe 725, removing any mist that may have formed on its inner surface. The absorbent cotton sheet 724 within the copper tube 721 helps to increase the dryness of the air.

[0083] Automatic cleaning: When the protective cover 404 rotates, it contacts the end of the housing 1, which scrapes off the saliva on the outer surface of the protective cover 404, thereby achieving an automatic cleaning function and maintaining transparency and shooting effect.

[0084] Safety locking function:

[0085] The fixing mechanism 8 is designed to respond to the patient's physiological reactions. If the patient experiences discomfort and retches, the tongue pushes against the tongue depressor 5, compressing the air in the spring airbag 813. The air then passes through the first air inlet pipe 814, the annular air storage groove 811, and the second air inlet pipe 822, entering the second hollow cylinder 821. This pushes the second piston plate 824 upward, causing the locking element 826 to engage the locking groove 607 at the bottom of the movable rod 602, restricting the rotation of the camera mechanism 4 and preventing friction with the tongue that could cause discomfort or injury.

[0086] The foregoing is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained herein shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
