Description

Technical Field

[0001] This invention relates to the field of mouth opener technology, specifically to a mouth opener device for oral examination of children. Background Technology

[0002] Children's oral health is an important part of their overall health. Regular dental checkups help detect and prevent oral diseases early, ensuring the normal development of children's teeth and maxillofacial region. Through regular dental checkups, not only can oral diseases be detected and treated in a timely manner, but children can also develop good oral hygiene habits, laying the foundation for lifelong oral health. Mouth openers used in pediatric dental examinations are medical instruments used to keep children's mouths open during dental examinations and treatments, allowing doctors to better operate and observe. Common types include metal mouth openers, usually made of stainless steel or other alloy materials. They have high strength and stability, can withstand large opening forces, and are not easily deformed. The surface of metal mouth openers is specially treated to be smooth and burr-free, avoiding damage to children's oral tissues. They are suitable for some more complex dental treatments, such as orthodontics and oral surgery, where greater opening force and stability are required.

[0003] In existing mouth-opening devices, when children are examined, the device compresses their gums as it opens their mouths. Children are also prone to crying and moving around during the examination, which can damage their gums, cause pain, and affect the examination and treatment. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A mouth-opening device for pediatric oral examination, comprising:

[0006] The arc rods are of two types, and each of the non-opposing surfaces of the arc rods has an arc groove.

[0007] An adjustment mechanism is installed between the arc rods, and the adjustment mechanism is symmetrically installed along the center position of the axis of the arc rods;

[0008] An occlusal mechanism, which is mounted on the opposite side of an arc bar and is used to provide occlusal support for teeth;

[0009] Each arc-shaped rod has a lip pad engaged at its arc-shaped groove. The side of the lip pad closest to the adjustment mechanism has an inclined surface that slopes outward from top to bottom, and the bottom of the lip pad closest to the occlusal mechanism has a protrusion. By utilizing the cooperation between the inclined surface and the protrusion, when the lip pad is placed in the child's mouth, the inclined surface contacts the inner side of the lip to support the lip, while the teeth contact the protrusion. The gap between the protrusion provides space for the child's gums. Combined with the deformation of the rubber material, this reduces pressure on the child's gums, avoiding pain caused by pressure and increasing discomfort during the examination, which could affect the doctor's examination and treatment. Both ends of the arc-shaped rod have end grooves, and side pads are engaged at each end groove. The outer side of the side pads is arc-shaped, and both the side pads and the lip pads are made of rubber material, which has deformation characteristics.

[0010] Preferably, the occlusal mechanism includes a retaining post, on which the opposing surfaces of the arc rod are fixedly installed, and the retaining post is symmetrically installed along the center position of the arc rod's axis. A connecting plate is fixedly installed at the end of the retaining post away from the arc rod. Occlusal plates are fixedly installed on the outer sides of the connecting plate, and oblique bite plates are fixedly installed on the opposing surfaces of the occlusal plates. Through the cooperation of the oblique bite plates and the inner bite plate, when the patient's teeth bite towards the occlusal plates, the teeth are positioned between the oblique bite plates and the inner bite plate, restricting the position of the teeth and preventing the arc rod from moving extensively within the oral cavity. This avoids movement of the arc rod during examination, which could lead to oral damage and bleeding when the oral cavity is opened. The oblique bite plates are symmetrically installed along the center position of the occlusal plate's axis, with the ends of the oblique bite plates that are close to each other inclined towards the side closer to the adjustment mechanism. An inner bite plate is fixedly installed at the center position of the side of the occlusal plate away from the adjustment mechanism, and the inner bite plate is located between the oblique bite plates.

[0011] Preferably, the adjusting mechanism includes a connecting rod, which is fixedly installed on the opposite side of the arc rod and symmetrically installed along the center of the arc rod's axis. A circular groove is formed at the end of the connecting rod away from the arc rod, and a rubber washer is engaged at each of the circular grooves. A shaft is rotatably mounted on the inner wall of each rubber washer. Through the cooperation of the shaft and the rubber washer, when the patient's mouth is opened, the elastic deformation of the rubber washer provides a certain range of biting motion for the patient, increasing the comfort of pediatric patients during examination without affecting the examination operation. A circular groove block is installed between the connecting rods, and fasteners are provided on both the upper and lower sides of the circular groove block. The circular groove block is rotatably connected to the two outer ends of the shaft through the fasteners.

[0012] Preferably, a through groove is formed at the center of the outer side of the circular groove block, a rubber pad ring is engaged with the inner wall of the circular groove block, and a rotating ring is slidably installed on the inner wall of the circular groove block. The rotating ring is located on the side of the rubber pad ring away from the arc rod. Through the deformation of the rubber pad ring, when the threaded cylinder is rotated and the patient's mouth is opened, the patient's biting pressure keeps the two end blocks in the same position, avoiding different opening angles on both sides. At the same time, in conjunction with the deformation of the rubber pad ring, the patient's comfort when the mouth is opened is improved. A pad ring is slidably installed between the rotating ring and the rubber pad ring. The pad ring has protrusions evenly arranged on the side near the rotating ring, and the pad ring contacts the rotating ring through the protrusions.

[0013] Preferably, a threaded cylinder is fixedly connected to the inner wall of the rotating ring. The protrusion of the washer ring engages with the rotating ring, reducing the contact area between the washer ring and the rotating ring. This reduces the friction between the rotating ring and the washer ring when the threaded cylinder is rotated, thus reducing rotational resistance and facilitating the device to open the patient's mouth. A lead screw is threadedly connected to the inner wall of the threaded cylinder. An end block is fixedly connected to the end of the lead screw away from the threaded cylinder. A rotating head is fixedly installed at the end of the threaded cylinder away from the lead screw. A buckle plate is fixedly installed on the side of the connecting rod opposite to the arc rod. Rotating rods are rotatably installed on both the upper and lower sides of the end block. The end of the rotating rod away from the end block is rotatably connected to the inner wall of the buckle plate.

[0014] This invention provides a mouth-holding device for oral examinations in children. It has the following beneficial effects:

[0015] I. This oral examination device for children uses a lip pad with an inclined surface and a protrusion. When inserted into the child's mouth, the inclined surface contacts the inside of the lip to support it, while the teeth contact the protrusion. The gap between the protrusion provides space for the child's gums. Combined with the deformation of the rubber material, this reduces pressure on the child's gums, avoiding pain caused by pressure, increasing discomfort during the examination, and affecting the doctor's examination and treatment.

[0016] Second, this dental examination device for children uses a combination of an oblique bite plate and an internal bite plate to position the teeth between them when the patient bites down on the bite plate. This restricts the position of the teeth and prevents the arc rod from moving too far within the mouth, thus avoiding damage to the oral cavity caused by the arc rod moving during the examination and preventing bleeding when the mouth is opened.

[0017] Third, this mouth-opening device for pediatric oral examinations, through the cooperation of a shaft and a rubber washer, provides a certain range of biting motion for the patient when the mouth is opened, through the elastic deformation of the rubber washer, thereby increasing the comfort of pediatric patients during the examination without affecting the examination operation.

[0018] IV. This oral examination mouth-opening device for children uses the deformation of the rubber gasket ring to open the patient's mouth by rotating the threaded cylinder. The patient's biting pressure keeps the two end blocks in the same position, avoiding different opening angles on both sides. At the same time, the deformation of the rubber gasket ring improves the patient's comfort when opening the mouth.

[0019] 5. This oral cavity opening device for pediatric oral examination uses a protruding washer that engages with a rotating ring. By utilizing the protrusion of the washer to contact the rotating ring, the contact area between the washer and the rotating ring is reduced, thereby reducing the friction between the rotating ring and the washer when the threaded cylinder is rotated, reducing rotational resistance, and making it easier for the device to open the patient's oral cavity.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] First embodiment, such as Figures 1 to 4 As shown, the present invention provides a technical solution:

[0031] A mouth-opening device for pediatric oral examination, comprising:

[0032] There are two arc rods 1, and each of the non-opposing surfaces of the arc rods 1 is provided with an arc groove 6;

[0033] Adjustment mechanism 2 is installed between the arc rods 1, and the adjustment mechanism 2 is symmetrically installed along the center position of the axis of the arc rods 1;

[0034] The occlusal mechanism 3 is mounted on the opposite side of the arc bar 1 and is used to provide occlusal support for the teeth.

[0035] Each of the arc grooves 6 of the arc rod 1 is fitted with a lip pad 4. The side of the lip pad 4 closest to the adjustment mechanism 2 has an inclined surface that slopes outward from top to bottom. When the arc rod 1 is inserted into the child patient's mouth, it is positioned between the lips and teeth. After insertion, the inclined surface of the lip pad 4 contacts the inner side of the child patient's lips, while the protrusion of the lip pad 4 contacts the outer side of the teeth. This, combined with the patient's biting action against the occlusal mechanism 3, positions the child patient's gums at the curved gap at the top of the protrusion of the lip pad 4, in conjunction with the rubber shape of the lip pad 4. The design features a deformable feature that reduces pressure on the gums of pediatric patients. The bottom of the lip pad 4 near the occlusal mechanism 3 has a protrusion. Both ends of the arc rod 1 have end slots 7, and side pads 5 are engaged at the end slots 7 of the arc rod 1. The outer side of the side pads 5 is arc-shaped. After the arc rod 1 is placed between the patient's lips and teeth, the side pads 5 are located on both sides between the lips and teeth. The arc shape of the outer side of the side pads 5 allows the arc rod 1 to be engaged in the gap. Both the side pads 5 and the lip pad 4 are made of rubber and have deformable properties.

[0036] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figure 5As shown, the occlusal mechanism 3 includes a retaining post 31, on which the opposite face of the arc rod 1 is fixedly installed. The retaining post 31 is symmetrically installed along the center position of the axis of the arc rod 1. A connecting plate 32 is fixedly installed at the end of the retaining post 31 away from the arc rod 1. Occlusal plates 34 are fixedly installed on the outer side of the connecting plate 32. After being placed in the oral cavity of a child patient, the child bites onto the occlusal plates 34. When the occlusal plates 34 are bitten, the oblique bite plate 33 is positioned on the outer side of the teeth, while the inner bite plate 35 is positioned on the inner side of the teeth. Oblique bite plates 33 are fixedly installed on the opposite face of the occlusal plates 34. The inclined bite plates 33 are symmetrically installed at the center of the axis of the occlusal plate 34. The ends of the inclined bite plates 33 that are close to each other are inclined towards the side closer to the adjustment mechanism 2. After biting, the teeth are restricted by the inclined bite plates 33 and the inner bite plate 35. During the process of opening the patient's oral cavity, the restriction of the teeth is used to position the occlusal mechanism 3, so that the arc rod 1 reduces the sliding of the arc rod 1 in the oral cavity during the examination due to the restriction. The inner bite plate 35 is fixedly installed at the center of the side of the occlusal plate 34 away from the adjustment mechanism 2. The inner bite plate 35 is located between the inclined bite plates 33.

[0037] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 6 to 8 As shown, the adjustment mechanism 2 includes a connecting rod 201, which is fixedly installed on the opposite side of the arc rod 1. The connecting rod 201 is symmetrically installed along the center position of the axis of the arc rod 1. A circular groove is opened at the end of the connecting rod 201 away from the arc rod 1. A rubber washer 207 is snapped into the circular groove of the connecting rod 201. A shaft 204 is rotatably installed on the inner wall of the rubber washer 207. In the adjustment mechanism 2, when the arc rod 1 is placed in the patient's mouth, the doctor rotates the rotating head 209, which drives the threaded cylinder 208 and the rotating ring 211 to rotate in the circular groove block 210. A circular groove block 210 is installed between the connecting rods 201. Fasteners are provided on both the upper and lower sides of the circular groove block 210, and the circular groove block 210 is rotatably connected to the two ends of the outer side of the shaft 204 through the fasteners.

[0038] A through groove is provided at the center of the outer side of the circular groove block 210. A rubber pad ring 212 is engaged with the inner wall of the circular groove block 210, and a rotating ring 211 is slidably installed on the inner wall of the circular groove block 210. The rotating ring 211 is located on the side of the rubber pad ring 212 away from the arc rod 1. When it is necessary to open the oral cavity, during rotation, the threaded connection between the threaded cylinder 208 and the lead screw 205 is used to bring the end block 206 close to the circular groove block 210, so that the rotating rod 202 rotates between the connecting rod 201 and the end block 206, opening the connecting rod 201 and increasing the included angle between the connecting rods 201, thus opening the patient's oral cavity. A pad ring 213 is slidably installed between the rotating ring 211 and the rubber pad ring 212. The pad ring 213 has protrusions evenly arranged on the side of the rotating ring 211, and the pad ring 213 contacts the rotating ring 211 through the protrusions.

[0039] A threaded cylinder 208 is fixedly connected to the inner wall of the rotating ring 211. A lead screw 205 is threadedly connected to the inner wall of the threaded cylinder 208. An end block 206 is fixedly connected to the end of the lead screw 205 away from the threaded cylinder 208. A rotating head 209 is fixedly installed at the end of the threaded cylinder 208 away from the lead screw 205. A buckle plate 203 is fixedly installed on the side of the connecting rod 201 away from the arc rod 1. During the opening process, the rubber pad ring 212 cooperates with the rubber washer 207 to provide a certain buffer range during the opening of the oral cavity. Rotating rods 202 are rotatably installed on both the upper and lower sides of the end block 206. The end of the rotating rod 202 away from the end block 206 is rotatably connected to the inner wall of the buckle plate 203.

[0040] When using the device, the lip pad 4 and side clip 5 are installed into the arc rod 1 when the device is placed in the child's mouth. Then, the arc rod 1 is placed inside the child's mouth, so that the arc rod 1 is between the lips and teeth. At the same time, the child bites on the occlusal mechanism 3. Then, according to the needs of the patient's oral examination, the doctor adjusts the mechanism 2 to increase the distance between the arc rods 1, opening the patient's mouth to facilitate the examination and treatment of the patient's oral cavity.

[0041] In use, the arc rod 1 is inserted into the child patient's mouth, positioned between the lips and teeth. After insertion, the inclined surface of the lip pad 4 contacts the inner side of the child patient's lips, while the protrusion of the lip pad 4 contacts the outer side of the teeth. This, combined with the patient's biting action on the occlusal mechanism 3, positions the child patient's gums at the curved gap at the top of the protrusion of the lip pad 4. The rubber deformation properties of the lip pad 4 reduce pressure on the child patient's gums. After the arc rod 1 is inserted between the patient's lips and teeth, the side retainers 5 are positioned on both sides between the lips and teeth. The arc shape of the outer side of the side retainers 5 secures the arc rod 1 within the gap.

[0042] In the occlusal mechanism 3, after being placed in the oral cavity of a child patient, the child bites onto the occlusal plate 34 with their teeth. When the child bites onto the occlusal plate 34, the oblique bite plate 33 is positioned on the outside of the teeth, while the inner bite plate 35 is positioned on the inside of the teeth. After biting, the teeth are restricted by the oblique bite plate 33 and the inner bite plate 35. During the process of opening the patient's oral cavity, the restriction of the teeth is used to position the occlusal mechanism 3, so that the arc rod 1 reduces the sliding of the arc rod 1 in the oral cavity during the examination due to the restriction.

[0043] In the adjustment mechanism 2, after the arc rod 1 is placed in the patient's mouth, the doctor rotates the rotating head 209, which drives the threaded cylinder 208 and the rotating ring 211 to rotate within the circular groove block 210. When it is necessary to open the mouth, during rotation, the threaded connection between the threaded cylinder 208 and the lead screw 205 is used to bring the end block 206 close to the circular groove block 210, causing the rotating rod 202 to rotate between the connecting rod 201 and the end block 206, thus opening the connecting rod 201 and increasing the included angle between the connecting rods 201, thereby opening the patient's mouth. At the same time, during the opening process, the rubber pad ring 212 and the rubber washer 207 cooperate to provide a certain buffer range during the process of opening the mouth.
