Abstract
Description
Technical Field
[0001] This invention relates to the field of dental treatment instruments, and more specifically, to a clinical diagnostic device for dental pulp and endodontics. Background Technology
[0002] Current diagnostic methods for dental caries and pulpitis typically involve the patient opening their mouth while medical staff use tools and a mirror to observe and examine the oral cavity. This method is prone to blind spots and takes a considerable amount of time; prolonged mouth-opening can also cause muscle soreness on both sides when chewing.
[0003] To address the aforementioned technical issues, Chinese invention patent (CN111494053A) discloses a clinical diagnostic device for oral cavity and dental pulp. This invention patent uses a miniature panoramic camera installed at the end of a connecting rod to examine the patient's oral cavity and dental pulp. However, before the examination, the patient needs to bite down on a mouth flare before the miniature panoramic camera is inserted into the oral cavity to examine the dental pulp. This diagnostic method is inefficient. Summary of the Invention
[0004] The purpose of this invention is to provide a clinical diagnostic device for dental pulp and endodontics. This diagnostic device can simultaneously open the oral cavity support device while inserting the camera into the patient's oral cavity, reducing the need to provide the patient with a mouth squeegee and improving diagnostic efficiency.
[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a clinical diagnostic device for dental pulp and endodontics, comprising a base plate and a diagnostic observation device. The top of the base plate is provided with a head support device and a support plate. A rectangular through-hole is formed in the side wall of the support plate. Two U-shaped grooves communicating with the rectangular through-hole are provided on the support plate. A slider and two sets of height adjustment devices are provided within the rectangular through-hole and the grooves. The slider is simultaneously fitted onto the two sets of height adjustment devices, each located within one of the two grooves. The slider is also movably fitted onto the diagnostic observation device. Two support rods are provided on the side wall of the slider near the head support device. The two support rods are symmetrically arranged on both sides of the diagnostic observation device along the slider's height direction. Oral support devices are provided at the ends of the two support rods away from the slider. The oral support devices are movably connected to both the support rods and the diagnostic observation device.
[0006] The diagnostic observation device includes a telescopic cylinder, an annular fixing plate, a spring, two protrusions, and a rotating mechanism. The slider is movably sleeved on the telescopic cylinder. The annular fixing plate, spring, and push plate are all located on the side of the slider away from the head support device. The annular fixing plate is fixedly sleeved on the outer wall of the telescopic cylinder. Spring is also sleeved on the telescopic cylinder, and both ends of spring are fixedly connected to the slider and the annular fixing plate, respectively. The two protrusions are located on the side of the slider closer to the head support device, and the two protrusions are fixedly installed on the horizontal sides of the telescopic cylinder. The two oral support devices are respectively sleeved on the two protrusions. The rotating mechanism is disposed throughout the telescopic cylinder.
[0007] The oral cavity support device includes a folded rod, a support block, and a baffle. The folded rod has a second through-groove on its side wall near the telescopic cylinder. The folded rod is sleeved on a protrusion, allowing the protrusion to move along the second through-groove. The end of the folded rod away from the telescopic cylinder is detachably connected to the support block, and the side wall of the folded rod near the support block is movably connected to the side wall of the support rod. The baffle is fixedly connected to the top of the support block.
[0008] A display screen is fixedly mounted on the side wall of the support plate away from the head support device.
[0009] By adopting the above technical solution, the telescopic cylinder passes through the slider and is movably connected to the slider. This allows medical staff to push the telescopic cylinder to insert the camera into the patient's mouth for diagnosis. The two ends of spring one are fixedly connected to the slider and the annular fixing plate, respectively. The annular fixing plate is also fixedly fitted onto the telescopic cylinder. After diagnosis, the spring force allows the telescopic cylinder to return to its initial state, improving operational convenience. A second groove is opened on the side wall of the folded rod, with a protrusion located within it and able to slide along it. Simultaneously, the side wall of the folded rod near the other end is movably connected to the side wall of the support rod. When the telescopic cylinder moves towards the patient's mouth, the two support blocks fixed to the folded rod move away from each other, providing support when the patient opens their mouth. This eliminates the need for the patient to wear a mouthpiece, improving diagnostic efficiency. The support blocks are detachably connected to the folded rod, facilitating support block replacement and ensuring hygienic conditions during the diagnostic process.
[0010] The invention is further configured such that: the rotating mechanism includes a knob, a rotating shaft, two support rods, a rotating block, multiple lights, and a camera; the rotating shaft extends through the telescopic cylinder, with one end of the rotating shaft fixedly connected to the knob, and the end of the rotating shaft away from the knob simultaneously fixedly connected to the two support rods; the rotating block is located between the two support rods, and its two side walls are rotatably connected to the two support rods respectively; both the rotating block and the knob are located outside the telescopic cylinder; the side wall of the rotating block away from the telescopic cylinder is simultaneously fixedly connected to the camera and the lights, and the multiple lights are distributed around the camera.
[0011] By adopting the above technical solution, the two sides of the rotating block are movably connected to the support rod. This allows the rotating block to rotate, which in turn drives the camera to rotate. This enables diagnosis of every surface of the teeth in the oral cavity from multiple angles, allowing for a full mouth examination and automatic saving of captured images, thus improving diagnostic efficiency. Installing multiple lights around the camera avoids shadows and improves the field of vision during the diagnostic process.
[0012] The invention is further configured such that: the top of the telescopic cylinder is provided with a push plate for pushing the telescopic cylinder back and forth.
[0013] By adopting the above technical solution, the push plate makes it easier for medical staff to move the entire telescopic cylinder back and forth.
[0014] The invention is further configured such that: the height adjustment device includes a stepper motor, a bearing, and a threaded rod; the stepper motor and the bearing are respectively installed on the top and bottom of the slide groove, and the top and bottom of the threaded rod are respectively fixedly connected to the output end of the stepper motor and the bearing; the slider is movably sleeved on the threaded rod.
[0015] By adopting the above technical solution, the slider is sleeved on the threaded rod. When the stepper motor rotates, the slider is limited by the first slide groove, so that the slider can only move up and down. This allows the height of the telescopic cylinder to be adjusted, ensuring that the telescopic cylinder is at the same level as the patient's oral cavity, making it convenient for medical staff to insert the camera into the patient's oral cavity.
[0016] The present invention is further configured such that: the head support device includes an arc-shaped support plate, a soft pad, and a support column; the bottom of the support column is fixedly connected to the top of the base plate, the bottom of the arc-shaped support plate is fixedly connected to the top of the support column, and the soft pad is attached to the concave surface of the arc-shaped support plate.
[0017] By adopting the above technical solution, soft pads are attached to the curved support plate, improving patient comfort.
[0018] The present invention is further configured such that: an air tube is provided inside the rotating shaft, and the air tube is arranged to pass through the rotating shaft and the knob along the length direction.
[0019] By adopting the above technical solution, by installing an air tube and blowing air through the air tube to the camera, water mist can be avoided from forming on the camera surface. In addition, since saliva may occasionally stick to the surface of the teeth and affect observation, the air tube can remove the saliva from the tooth surface by blowing air.
[0020] In summary, the present invention has the following beneficial effects:
[0021] 1. The telescopic cylinder passes through the slider and is movably connected to the slider, so that medical staff can push the telescopic cylinder to send the camera into the patient's mouth to complete the diagnosis;
[0022] 2. Fix the two ends of spring one to the slider and the annular fixing plate respectively. At the same time, fix the annular fixing plate to the telescopic cylinder. After the diagnosis is completed, the telescopic cylinder can be directly returned to the initial state by the elastic force of the spring, which improves the convenience of operation.
[0023] 3. A second groove is made on the side wall of the folding rod, and the protrusion is located in the second groove and can slide along the second groove. At the same time, the side wall of the folding rod near the other end is movably connected to the side wall of the support rod. In this way, when the telescopic cylinder moves towards the patient's mouth, the two support blocks fixed on the folding rod will move away from each other, thereby providing support when the patient opens his mouth. This eliminates the need for the patient to wear a mouthpiece and improves diagnostic efficiency.
[0024] 4. The support block and the folded rod are detachably connected, which facilitates the replacement of the support block and ensures a hygienic environment during the diagnostic process. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-6 The present invention will be described in further detail below.
[0033] Example: A clinical diagnostic device for dental pulp and endodontics, such as Figures 1 to 6 As shown, the device includes a base plate 1 and a diagnostic observation device. A head support device and a support plate 11 are fixedly installed on the top of the base plate 1. A rectangular through hole 21 is formed in the side wall of the support plate 11, as shown in the figure. Figure 5 As shown, the support plate 11 has two U-shaped grooves 8 communicating with the rectangular through hole 21. The two U-shaped grooves 8 are located on both sides of the rectangular through hole 21. The slider 13 is located in the rectangular through hole 21 and the grooves 8. The slider 13 can slide up and down along the grooves 8. Height adjustment devices are also fixedly installed in the two grooves 8. The slider 13 is simultaneously sleeved on two sets of height adjustment devices. The slider 13 is also movably sleeved on the diagnostic observation device. Figure 1 As shown, two support rods 14 are fixedly installed on the side wall of the slider 13 near the head support device. The two support rods 14 are symmetrically arranged on both sides of the diagnostic observation device along the height direction of the slider 13. An oral support device is installed at the end of the two support rods 14 away from the slider 13. The oral support device and the support rod 14 are hinged, and the oral support device and the diagnostic observation device are slidably connected.
[0034] The diagnostic observation device includes a telescopic cylinder 4, an annular fixed plate 3, a spring 7, two protrusions 20, and a rotating mechanism; a slider 13 is movably sleeved on the telescopic cylinder 4, such as... Figure 1 As shown, the annular fixing plate 3, spring 7, and push plate 6 are all located on the side of the slider 13 away from the head support device; the annular fixing plate 3 is fixedly sleeved on the outer wall of the telescopic cylinder 4, and spring 7 is also sleeved on the telescopic cylinder 4, with both ends of spring 7 fixedly connected to the slider 13 and the annular fixing plate 3 respectively; two protrusions 20 are located on the side of the slider 13 closer to the head support device, and the two protrusions 20 are fixedly installed on the horizontal sides of the telescopic cylinder 4 respectively; two oral cavity support devices are respectively sleeved on the two protrusions 20; as Figure 5 As shown, the rotating mechanism is installed inside the telescopic cylinder 4;
[0035] The oral cavity support device includes a folding rod 18, a support block 26, and a baffle 24; such as Figure 1 As shown, a second groove 19 is provided through the folded rod 18 near the side wall of the telescopic cylinder 4, through which the folded rod 18 passes. The folded rod 18 is sleeved on the protrusion 20, causing the protrusion 20 to move along the second groove 19; Figure 2As shown, the support block 26 has a barb that is inserted into the groove of the folded rod 18. The barb of the support block 26 is fixed to the folded rod 18 by a hand screw 27. After diagnosing a patient's tooth, the support block 26 can be replaced by turning the hand screw 27. The side wall of the folded rod 18 near the support block 26 is hinged to the side wall of the support rod 14, so that the folded rod 18 can rotate around the hinge position. The baffle 24 is fixedly connected to the top of the support block 26. The baffle 24 is used to cover the lip position. Preferably, a shallow tooth socket 25 can be opened in the top of the support block 26. The tooth socket 25 is used to fix the tooth.
[0036] A display screen 10 is fixedly installed on the side wall of the support plate 11 away from the head support device. The display screen 10 is preferably a touch display screen 10, so that the display screen 10 can not only display the real-time image captured by the camera 16, but also control the electrical components through the display screen 10.
[0037] The rotating mechanism includes a knob 5, a rotating shaft 30, two support rods 29, a rotating block 17, multiple lights 15, and a camera 16; as shown Figure 5 As shown, the rotating shaft 30 extends through the telescopic cylinder 4. The end of the rotating shaft 30 is fixedly connected to the knob 5, and the end of the rotating shaft 30 away from the knob 5 is simultaneously fixedly connected to two support rods 29. The rotating block 17 is located between the two support rods 29, and its two side walls are rotatably connected to the two support rods 29 respectively. The rotatable connection method is as follows: Figure 6 As shown, a micro motor 31 and a bearing 32 are respectively embedded inside the two support rods 29. The micro motor 31 is preferably a stepper motor 12 that can rotate forward and backward. The output end of the micro motor 31 is fixedly connected to the side wall of the rotating block 17. The other side wall of the rotating block 17 is rotated by inserting a rotating rod into the bearing 32. The rotating block 17 and the knob 5 are both located outside the telescopic cylinder 4. The length of the rotating shaft 30 is longer than that of the telescopic cylinder 4, so the rotating shaft 30 can slide back and forth inside the telescopic cylinder 4 to realize the back and forth movement of the camera 16. The side wall of the rotating block 17 away from the telescopic cylinder 4 is fixedly connected to both the camera 16 and the lighting lamp 15. Figure 6 As shown, multiple lights 15 are distributed around the camera 16.
[0038] A push plate 6 is fixedly installed on the top of the telescopic cylinder 4 to push the telescopic cylinder 4 back and forth, so that the front and rear positions of the telescopic cylinder 4 and the rotating shaft 30 can be adjusted independently.
[0039] The height adjustment device includes a stepper motor 12, a bearing 2, and a threaded rod 9; the stepper motor 12 and the bearing 2 are respectively installed on the top and bottom of the slide groove 8, and the top and bottom of the threaded rod 9 are respectively fixedly connected to the output end of the stepper motor 12 and the bearing 2; the slider 13 is movably sleeved on the threaded rod 9 and threadedly connected.
[0040] The head support device includes an arc-shaped support plate 22, a soft pad 28, and a support column 23; the bottom of the support column 23 is fixedly connected to the top of the base plate 1, the bottom of the arc-shaped support plate 22 is fixedly connected to the top of the support column 23, and the soft pad 28 is attached to the concave surface of the arc-shaped support plate 22.
[0041] like Figure 5 As shown, an air tube 33 is installed inside the rotating shaft 30. The air tube 33 runs through the rotating shaft 30 and the knob 5 along their length. The air tube 33 can be connected to an inflation device (not shown in the figure). This allows air to be blown onto the camera 16 when the rotating block 17 is rotated to the 90-degree position, thus preventing water mist from forming on the surface of the camera 16. In addition, since the rotating block 17 can rotate at a certain angle, the airflow blown in by the air tube 33 can flow diagonally upward or downward, which can remove saliva from the tooth surface.
[0042] Working principle: When medical staff diagnose a patient's dental pulp, the patient's head is placed on the arc-shaped support plate 22. The medical staff adjusts the height of the camera 16 through the display screen 10. The display screen 10 transmits the input information to the control processor (not shown in the figure). The control processor adjusts the stepper motor 12 to rotate, which drives the threaded rod 9 to rotate. Since the slider 13 is sleeved on the threaded rod 9, the slider 13 can drive the telescopic cylinder 4, the camera 16, and the support rod 14 to rise and fall simultaneously, so that the camera 16 is at the same level as the patient's oral cavity. Then, the patient opens their mouth and pushes the push plate 6, which compresses the spring 7 of its annular fixing plate 3. At the same time, the protrusion 20 moves forward. At this time, the distance between the protrusion 20 and the hinge position of the support rod 14 and the folded rod 18 decreases, so the protrusion 20 will move forward along the slide groove 19. At the same time, the folded rod 18 will rotate around its hinge position with the support rod 14, which increases the distance between the two support blocks 26. After the camera 16 enters the oral cavity, the patient can place the tooth... Within the alveolar ridge 25, this provides support for the patient's oral cavity. Simultaneously, the real-time image captured by the camera 16 is displayed on the screen 10. During the recording process, images can be stored in real-time, and individual images can be captured. Medical staff can adjust the shooting angle by using an angle adjustment button (not shown in the diagram) to rotate the micro-motor-driven rotating block, allowing observation of each surface of the tooth. Medical staff can also move the camera 16 to the optimal position for shooting by pushing or rotating the knob 5. The illumination lamp 15 is preferably an LED light, with multiple lamps 15 surrounding the camera 16 to improve the field of view. After the diagnosis, releasing the push plate 6 causes the annular fixing plate 3 to return the telescopic cylinder 4 to its initial position under the action of spring 7, reducing the workload for medical staff. After the diagnosis, loosening the hand screw 27 allows the support block 26 and baffle 24 to be removed and replaced with new ones, facilitating use by the next patient.
[0043] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
