Description

Technical Field

[0001] The present invention relates to the technical field of oral medical devices, and particularly relates to an oral mirror for oral medicine. Background Art

[0002] With the increasing emphasis on oral health by people, the demand for oral examinations and treatments by the public has also been increasing day by day, which has gradually raised the requirements for oral medical devices and medical technologies.

[0003] The working principle of the existing medical oral mirror is mainly to reflect the light source onto a magnifying glass, and then project the light on the magnifying glass onto the area to be examined inside the oral cavity. The user can observe the details and structures inside the oral cavity for detection and diagnosis; the oral mirror can magnify the details inside the oral cavity, making it easier for doctors to observe and examine, and accurately diagnose and treat oral diseases. However, the oral mirrors in the existing technology usually need to be held by doctors, which makes it inconvenient for doctors to treat the patient's oral cavity when observing the patient's oral cavity with the oral mirror.

[0004] In summary, how to solve the problem that the oral mirrors in the existing technology usually need to be held by doctors, which makes it inconvenient for doctors to treat the patient's oral cavity when observing the patient's oral cavity with the oral mirror has become a difficult problem that needs to be solved urgently in the current field. Therefore, it is necessary to propose an oral mirror for oral medicine that can free the doctor's hands and facilitate the doctor to treat the patient. Summary of the Invention

[0005] To solve the above problems, the present invention provides an oral mirror for oral medicine. Through the design of the clamping assembly, it can effectively free the doctor's hands, improve the efficiency of the doctor's observation and treatment of the patient's oral cavity, reduce the fatigue degree of the doctor's hands at the same time, and reduce the time for the doctor to frequently replace surgical instruments, thereby improving the treatment quality.

[0006] To achieve the above object, the technical solution of the present invention is as follows: An oral mirror for oral medicine includes a lens, and a telescopic assembly for telescoping the lens is provided on one side of the lens. The telescopic assembly includes a protective shell and a controller. A telescopic rod is fixedly connected to the inner side wall of the protective shell, and the controller is used to control the operation of the telescopic rod.

[0007] A clamping assembly for fixing the whole device is provided at the bottom of the protective shell. The clamping assembly includes a first clamping block and a second clamping block. The first clamping block is fixedly connected to the protective shell, and a tension spring is fixedly connected between the first clamping block and the second clamping block; a reverse T-shaped frame is also fixedly connected to the bottom of the protective shell, and both ends of the reverse T-shaped frame are fixedly connected and hinged to the first clamping block and the second clamping block respectively; a pressing block is integrally formed on the side of the second clamping block away from the reverse T-shaped frame.

[0008] The technical principle of the above solution is as follows:

[0009] The doctor pinches the pressing block and the protective shell, and the second clamping block starts to rotate. The bottom of the second clamping block moves away from the bottom of the first clamping block, and the patient's dental arch is placed in the gap between the first clamping block and the second clamping block. The doctor releases the pressing block and the protective shell, and the tension spring pulls the second clamping block, causing the second clamping block to rotate and reset. The bottom of the second clamping block approaches the bottom of the first clamping block, clamping the patient's dental arch.

[0010] The above - mentioned scheme has the following beneficial effects:

[0011] 1. Through the design of the mutual clamping of the first clamping block and the second clamping block in the present invention, the lens can be stably fixed in the patient's oral cavity without the doctor holding it by hand, so that the doctor can free both hands and better perform surgical treatment on the patient's oral cavity. And because the present invention can free the doctor's hands, it can greatly reduce the hand fatigue of the doctor caused by holding the oral mirror for a long time, so that the doctor can have better energy to perform surgical treatment on the patient's oral cavity, thus improving the surgical effect.

[0012] 2. In the prior art, since the doctor needs to switch back and forth between the oral mirror and various surgical instruments, the surgical time will be greatly extended, and at the same time, the physical consumption of the doctor will increase. The present invention provides the design of the clamping component, which can stably fix the oral mirror in the patient's oral cavity, so that the doctor does not need to switch back and forth between the oral mirror and other surgical instruments, thus greatly reducing the time wasted by switching surgical instruments during the operation, and at the same time reducing the physical consumption of the doctor, thereby improving the surgical quality.

[0013] 3. The operation of the present invention is simple. The doctor only needs to pinch the pressing block and the protective shell with the hand at the beginning of the operation, align the first clamping block and the second clamping block with the patient's dental arch and clamp them to complete the fixation of the lens. It only needs simple training to quickly master the operation, effectively reducing the operation difficulty and improving the operation efficiency.

[0014] Furthermore, a regulating component for adjusting the angle of the lens is provided at the output end of the telescopic rod; the regulating component includes a regulating shell, a driving member is fixedly connected to the inner side wall of the regulating shell, a first bevel gear is coaxially fixedly connected to the output shaft of the driving member, the first bevel gear meshes with a second bevel gear, and a rotating rod is fixedly connected to the bottom of the second bevel gear.

[0015] A third bevel gear is fixedly connected to the bottom of the rotating rod, the third bevel gear meshes with a fourth bevel gear, a connecting rod is fixedly connected to the side of the fourth bevel gear away from the third bevel gear, and one end of the connecting rod away from the fourth bevel gear is fixedly connected to the side wall of the lens.

[0016] An L-shaped tube is sleeved outside the rotating rod. Both the rotating rod and the connecting rod are rotatably fitted with the inner wall of the L-shaped tube. A sliding groove for the lower part of the L-shaped tube and the connecting rod to slide horizontally is formed on the side of the adjusting shell close to the lens; a secondary gear is fixedly sleeved on the outer wall of the upper part of the L-shaped tube; a rotating member for driving the L-shaped tube to rotate is fixedly connected to the inner bottom wall of the adjusting shell. The output shaft of the rotating member is coaxially and fixedly connected with a main gear, and the main gear meshes with the secondary gear; the controller is used to control the operation of the driving member and the rotating member.

[0017] Beneficial effects: The doctor adjusts the rotation of the driving member through the controller. The output shaft of the driving member drives the first bevel gear to rotate, and the first bevel gear drives the second bevel gear to rotate; the second bevel gear drives the third bevel gear to rotate by driving the rotating rod; the third bevel gear drives the fourth bevel gear to rotate; since the fourth bevel gear is fixedly connected to the connecting rod and the connecting rod is fixedly connected to the lens, the fourth bevel gear can adjust the angle of the lens by driving the connecting rod to rotate. Lenses at different angles can observe different positions of the patient's oral cavity, which is convenient for the doctor to observe the patient's oral cavity more carefully.

[0018] The doctor can also adjust the rotating member through the controller. The output shaft of the rotating member drives the main gear to rotate, and the secondary gear also starts to rotate. At the same time, the secondary gear drives the lower part of the L-shaped tube to slide horizontally at the sliding groove; and since the connecting rod is located inside the L-shaped tube, when the lower part of the L-shaped tube slides, it will drive the connecting rod to slide at the same time, thereby driving the lens to move horizontally, further expanding the observation range of the lens. The rotation and sliding of the lens cooperate with each other, enabling the doctor to observe the patient's oral cavity more comprehensively and improving the treatment effect.

[0019] Furthermore, a support assembly for supporting the patient's oral cavity is provided at the top of the protective shell; the support assembly includes a top rod, and the controller is used to control the operation of the top rod; the top of the output shaft of the top rod is coaxially and detachably connected with a support plate.

[0020] Beneficial effects: After fixing the lens, the doctor starts the top rod through the controller. The output shaft of the top rod drives the support plate to move upward, so that the support plate can fit the upper jaw of the patient's oral cavity, providing support for the patient's oral cavity, reducing the discomfort caused by the patient opening the oral cavity for a long time, reducing the physical consumption of the patient, and also keeping the patient's oral cavity in an expanded state, which is convenient for the doctor to observe and treat.

[0021] Furthermore, a protective opening is formed on the side of the protective shell close to the lens.

[0022] Beneficial effects: When the telescopic rod contracts, the lens can also be retracted into the protective shell through the protective opening along with the telescopic rod. Thus, when the lens is not in use, the protective shell can protect the lens.

[0023] Furthermore, a plurality of LED lights are fixedly connected to the outer wall of the adjusting shell, and the controller is used to control the on and off of the LED lights.

[0024] Beneficial effects: Since the light environment in the patient's oral cavity is poor, when the doctor observes and treats the patient's oral cavity, the doctor turns on the LED lamp through the controller, which can provide a good light environment for the doctor, thereby improving the effect of the doctor's observation and treatment of the patient's oral cavity.

[0025] Furthermore, the support plate is a disposable item, and the support plate is made into a corresponding shape according to the shape of the upper jaw of different patients by using 3D printing technology.

[0026] Beneficial effects: Since there are certain differences in the oral cavity environments of different patients and their upper jaw shapes are also different, the support plate is made into a corresponding shape according to the shape of the upper jaw of different patients by using 3D printing technology, enabling the support plate to better fit the patient's oral cavity and reducing the discomfort caused by long-term support for the patient; at the same time, the support plate is a disposable item, which can ensure the hygiene of the operation and improve the patient's treatment experience.

[0027] Furthermore, the support plate is made of medical silicone.

[0028] Beneficial effects: Medical silicone can not only meet the material requirements of 3D printing technology but also ensure the hygiene of the operation. Moreover, medical silicone has a certain hardness and good strain capacity, making the support of the support plate for the patient more comfortable.

[0029] Furthermore, wiping cloths for wiping the lens are fixedly connected to both the inner bottom wall and the inner top wall of the protective shell.

[0030] Beneficial effects: When the lens moves in the protective shell, the wiping cloths on the inner bottom wall and the inner top wall of the protective shell can wipe the lens, keeping the lens bright and clean, thereby improving the doctor's observation effect and the treatment quality.

[0031] Furthermore, a protective sleeve is sleeved on the pressing block.

[0032] Beneficial effects: When the doctor presses the pressing block, the protective sleeve can increase the friction between the doctor's hand and the pressing block, making the doctor more labor-saving; and the protective sleeve can wrap the pressing block, thereby protecting the doctor's hand and preventing the doctor's hand from being injured and affecting the operation.

[0033] Furthermore, the first Clamping block and the side walls of the second clamping blocks that are close to each other are both fixedly connected with anti-slip layers.

[0034] Beneficial effects: The anti-slip layer can increase the friction between the first Clamping block and the second clamping blocks and the patient's dental arch, enabling the first clamping block and the second clamping block to more firmly fix the lens and improving the doctor's observation effect; at the same time, the anti-slip layer can prevent the first Clamping block and the second clamping blocks from directly contacting the patient's dental arch, thereby avoiding the firstClamping block and the second clamping block cause harm to the patient's dental arch, improving the patient's treatment experience.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0040] The following will be further described in detail through specific embodiments:

[0041] Embodiment 1:

[0042] As shown in the Figures 1 - 3 drawing: An oral mirror for stomatology includes a lens, and a telescopic assembly for telescoping the lens is provided on one side of the lens.

[0043] The telescopic assembly includes a protective housing 1 and a controller. The inner side wall of the protective housing 1 is fixedly connected with a telescopic rod 2, and the controller is used to control the operation of the telescopic rod 2; a clamping assembly for fixing the whole device is provided at the bottom of the protective housing 1.

[0044] The clamping assembly includes a first clamping block 18 and a second clamping block 19. The first clamping block 18 is bolted and fixedly connected to the protective housing 1. A tension spring is bolted and fixedly connected between the first clamping block 18 and the second clamping block 19. A reversed T-shaped frame is also bolted and fixedly connected to the bottom of the protective housing 1. Two ends of the reversed T-shaped frame are respectively bolted and fixedly connected and hinged to the first clamping block 18 and the second clamping block 19; A pressing block 11 is integrally formed on one side of the second clamping block 19 away from the reversed T-shaped frame.

[0045] The output end of the telescopic rod 2 is provided with an adjusting component for adjusting the angle of the lens; the adjusting component includes an adjusting shell 3, and a driving member is fixedly connected to the inner side wall of the adjusting shell 3 by bolts. In this embodiment, the driving member is a first motor 4. The output shaft of the first motor 4 is coaxially and fixedly connected to a first bevel gear 5 by bolts. The first bevel gear 5 meshes with a second bevel gear 6. The bottom of the second bevel gear 6 is fixedly connected to a rotating rod 7 by bolts. The bottom of the rotating rod 7 is fixedly connected to a third bevel gear 8 by bolts. The third bevel gear 8 meshes with a fourth bevel gear 9. One side of the fourth bevel gear 9 away from the third bevel gear 8 is fixedly connected to a connecting rod 10 by bolts. One end of the connecting rod 10 away from the fourth bevel gear 9 is fixedly connected to the side wall of the lens by bolts.

[0046] An L-shaped tube 12 is sleeved outside the rotating rod 7. The rotating rod 7 and the connecting rod 10 are both rotationally matched with the inner wall of the L-shaped tube 12. A sliding groove for the lower part of the L-shaped tube 12 and the horizontal sliding of the connecting rod 10 is formed on one side of the adjusting shell 3 close to the lens; a secondary gear 13 is fixedly sleeved on the outer wall of the upper part of the L-shaped tube 12 by bolts. A rotating member for driving the L-shaped tube 12 to rotate is fixedly connected to the inner bottom wall of the adjusting shell 3 by bolts. In this embodiment, the rotating member is a second motor 14. The output shaft of the second motor 14 is coaxially and fixedly connected to a main gear 15 by bolts. The main gear 15 meshes with the secondary gear 13; the controller is used to control the operation of the driving member and the rotating member.

[0047] A supporting component for supporting the patient's oral cavity is provided at the top of the protective shell 1; the supporting component includes a top rod 16, and the controller is used to control the operation of the top rod 16; the top of the output shaft of the top rod 16 is coaxially and detachably connected to a support plate 17.

[0048] The specific implementation process is as follows:

[0049] Take Figure 1 as an example. First, the doctor pinches the pressing block 11 and the protective shell 1 with the hand, so that the tension spring is stretched, and the pressing block 11 and the protective shell 1 approach each other. Since one end of the bottom of the inverted T-shaped frame close to the first clamping block 18 is fixedly connected to the side wall of the first clamping block 18, and since one end of the bottom of the inverted T-shaped frame close to the second clamping block 19 is hinged to the second clamping block 19, the second clamping block 19 will start to rotate at this time, and the bottom of the second clamping block 19 will move away from the bottom of the first clamping block 18, and the patient's dental arch is placed in the gap between the first clamping block 18 and the second clamping block 19; at this time, the doctor releases the pressing block 11 and the protective shell 1, and the tension spring will pull the second clamping block 19 to rotate, so that the bottom of the second clamping block 19 approaches the bottom of the first clamping block 18 to clamp the patient's dental arch; at this time, the lens can be stably fixed inside the patient's oral cavity.

[0050] After the lens is fixed, the doctor starts the ejector rod 16 through the controller. The output shaft of the ejector rod 16 drives the support plate 17 to move upward, so that the support plate 17 can fit the upper jaw of the patient's oral cavity, providing support for the patient's oral cavity, reducing the discomfort caused by the patient opening the oral cavity for a long time, reducing the physical consumption of the patient, and also enabling the patient's oral cavity to maintain an expanded state, facilitating the doctor's observation and treatment. At the same time, the design of the support plate 17 also makes the fixation of the lens more stable, facilitating the doctor to adjust the angle and position of the lens subsequently.

[0051] Compared with the prior art, through the design of the first clamping block 18 and the second clamping block 19 clamping each other and the supporting effect of the support plate 17, the lens can be stably fixed in the patient's oral cavity without the doctor holding it by hand, so that the doctor can free both hands and better perform surgical treatment on the patient's oral cavity.

[0052] After the lens is fixed, the doctor adjusts the telescopic rod 2 through the controller to adjust the front and rear positions of the lens.

[0053] Take Figure 3 as an example. After the front and rear positions of the lens are adjusted, the doctor starts the first motor 4 through the controller. The output shaft of the first motor 4 drives the first bevel gear 5 to rotate. Since the first bevel gear 5 and the second bevel gear 6 are meshed, the first bevel gear 5 will drive the second bevel gear 6 to rotate; and since the second bevel gear 6 is bolted to the rotating rod 7, and the rotating rod 7 is also bolted to the third bevel gear 8, the second bevel gear 6 drives the rotating rod 7 to drive the third bevel gear 8 to rotate; since the third bevel gear 8 and the fourth bevel gear 9 are meshed, the third bevel gear 8 will drive the fourth bevel gear 9 to rotate; and since the fourth bevel gear 9 is bolted to the connecting rod 10, and the connecting rod 10 is bolted to the lens, the fourth bevel gear 9 can adjust the angle of the lens by driving the connecting rod 10 to rotate. Lenses at different angles can observe different positions of the patient's oral cavity, thus facilitating the doctor to observe the patient's oral cavity more carefully.

[0054] Meanwhile, the doctor can also adjust the second motor 14 through the controller. The output shaft of the second motor 14 drives the main gear 15 to rotate. Since the main gear 15 and the sub-gear 13 are meshed, and the sub-gear 13 is sleeved on the outer wall of the L-tube 12, the sub-gear 13 will rotate, and at the same time, the sub-gear 13 will drive the lower part of the L-tube 12 to slide horizontally at the chute; and since the connecting rod 10 is located inside the L-tube 12, when the lower part of the L-tube 12 slides, it will drive the connecting rod 10 to slide at the same time, thereby driving the lens to move horizontally, further expanding the observation range of the lens. In the present invention, the lens can slide back and forth, left and right, and can also adjust its own angle by self-rotation, enabling the doctor to observe the patient's oral cavity situation more comprehensively and improving the treatment effect.

[0055] In the prior art, since doctors need to switch back and forth between oral mirrors and various surgical instruments, the operation time will be significantly prolonged, and at the same time, the physical consumption of doctors will increase. The present invention provides a design of a clamping component, which can stably fix the oral mirror in the patient's oral cavity, so that doctors do not need to switch back and forth between the oral mirror and other surgical instruments, thus significantly reducing the time wasted due to switching surgical instruments during the operation, and at the same time reducing the physical consumption of doctors, thereby improving the operation quality.

[0056] The operation of the present invention is simple. When the operation starts, the doctor only needs to pinch the pressing block 11 and the protective shell 1 with the hand, and align the first clamping block 18 and the second clamping block 19 to clamp the patient's dental arch to complete the fixation of the lens. Only simple training is required to quickly master the operation, effectively reducing the difficulty of getting started and improving the operation efficiency.

[0057] Embodiment 2:

[0058] As shown in the attached Figures 1 - 2 figure: Different from the above embodiment, a protective opening is provided on the side of the protective shell 1 close to the lens; wiping cloths for wiping the lens are fixedly bonded to both the inner bottom wall and the inner top wall of the protective shell 1.

[0059] The specific implementation process is as follows: When the telescopic rod 2 contracts, the lens can also be retracted into the protective shell 1 through the protective opening along with the telescopic rod 2; so that when not in use, the protective shell 1 can protect the lens. When the lens moves in the protective shell 1, the wiping cloths on the inner bottom wall and the inner top wall of the protective shell 1 can wipe the lens to keep the lens bright and clean, thereby improving the doctor's observation effect and the treatment quality.

[0060] Embodiment 3:

[0061] As shown in the attached Figure 3 figure: Different from the above embodiment, a number of LED lights are fixedly bonded to the outer wall of the adjustment shell 3, and the controller is used to control the opening and closing of the LED lights.

[0062] The specific implementation process is as follows: When the doctor observes and treats the patient's oral cavity, since the light environment in the patient's oral cavity is relatively poor, the doctor can turn on the LED lights through the controller; the LED lights can provide a good light environment for the doctor, thereby improving the doctor's observation and treatment effect on the patient's oral cavity.

[0063] Embodiment 4:

[0064] As shown in the attached Figures 1 - 2 figure: Different from the above embodiment, the support plate 17 is a disposable item, and the support plate 17 is made into a corresponding shape according to the shape of the oral palate of different patients by using 3D printing technology; the support plate 17 is made of medical silicone.

[0065] The specific implementation process is as follows: During oral treatment, due to certain differences in the oral environments of different patients and the different shapes of their oral palates, the support plate 17 is made into a corresponding shape according to the shape of the oral palate of different patients by 3D printing technology, so that the support plate 17 can better fit the patient's oral cavity and reduce the discomfort caused by long-term support for the patient; at the same time, the support plate 17 is a disposable tool, which can ensure the hygiene of the operation and improve the treatment experience of the patient.

[0066] The support plate 17 is made of medical silicone. Medical silicone can not only meet the material requirements of 3D printing technology, but also ensure the hygiene of the operation. Moreover, medical silicone has a certain hardness and good strain ability, making the support of the support plate 17 for the patient more comfortable.

[0067] Example 5:

[0068] As shown in the attached Figures 1 - 2 figure: Different from the above embodiments, a protective sleeve is sleeved on the pressing block 11.

[0069] The specific implementation process is as follows: When the doctor presses the pressing block 11, the protective sleeve can increase the friction between the doctor's hand and the pressing block 11, making the doctor more labor-saving; and the protective sleeve can wrap the pressing block 11, thereby protecting the doctor's hand and preventing the doctor's hand from being injured and affecting the progress of the operation.

[0070] Example 6:

[0071] As shown in the attached Figures 1 - 2 figure: Different from the above embodiments, anti-slip layers are fixedly adhered to the side walls of the first clamping block 18 and the second clamping block 19 that are close to each other.

[0072] The specific implementation process is as follows: The anti-slip layer can increase the friction between the first clamping block 18 and the second clamping block 19 and the patient's dental arch, so that the first clamping block 18 and the second clamping block 19 can more firmly fix the lens and improve the doctor's observation effect; at the same time, the anti-slip layer can prevent the first clamping block 18 and the second clamping block 19 from directly contacting the patient's dental arch, thereby avoiding damage to the patient's dental arch by the first clamping block 18 and the second clamping block 19 and improving the treatment experience of the patient.

[0073] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
