Description

Technical Field

[0001] The present invention relates to the technical field of oral digital observation instruments, and particularly relates to an oral digital observation instrument with automatic focusing and shooting. Background Art

[0002] An oral digital observation instrument is a device used for image acquisition during oral examination, diagnosis, and treatment. It can capture high-definition images of the oral cavity interior, assisting doctors in making more accurate diagnoses and carrying out treatments.

[0003] In the prior art, the document with the publication number CN218279602U provides a dental oral digital observation instrument that prevents wire breakage. In this observation instrument, an anti-wire-breakage mechanism is provided on the observation device. During use, the power cord is electrically connected to the main body of the observation instrument, and the power cord is dragged. When rotating or swinging left and right, since the power cord is inserted and connected to the wire passing port, the spherical movable block will move in the spherical sliding groove during shaking, and the power cord will not contact the inside of the internal thread cover, thereby reducing friction and increasing the service life of the power cord. And a rubber ring is provided at the lower end of the through pipe to reduce the frictional damage of the power cord and reduce the probability of wire breakage due to long-term use.

[0004] When the prior art is in use, it is necessary to insert the observation instrument into the patient's mouth for observation. At this time, the surface of the observation instrument will be attached with the patient's oral secretions. The prior art lacks a self-cleaning function and cannot perform efficient automatic cleaning and disinfection after each use. The cleaning work relies on manual operation. This not only increases the cleaning time and labor intensity but also may lead to incomplete cleaning, thus affecting the hygiene standard of the device and even posing a risk of cross-infection to subsequent patients.

[0005] In summary, in the prior art, there is a lack of technology for automatically cleaning the part of the observation instrument inserted into the patient's mouth. Summary of the Invention

The trapezoidal block is linked with the moving seat to automatically close the sealing plate, thereby ensuring the sealing performance inside the cleaning base. It prevents liquid leakage during cleaning and ensures the sealing and cleaning effects of the cleaning process. At the same time, the transmission rack connected to the trapezoidal block drives the piston, which can accurately control the release amount of the cleaning liquid. The movement of the piston accurately squeezes the cleaning liquid in the temporary storage tube into the cleaning base to ensure that the usage amount of the cleaning liquid is appropriate, avoid waste, and also ensure the cleaning effect.

[0018] 3. By providing an oral cavity holding mechanism, it can effectively support the patient's oral cavity and avoid instability during the photographing process due to involuntary movement or chewing of the patient. Traditional hand-held photographing requires the operator to manually maintain the photographing angle, which not only increases the operation difficulty but also easily causes hand fatigue. Through the adjustable moving rod and rotating rod, the photographing angle can be accurately adjusted and stabilized, reducing the burden on the operator and improving the photographing efficiency.

[0021] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0022] As Figures 1-8 shown, an oral digital observation instrument with automatic focusing and shooting includes an inspection table 1, on which an instrument main body 2 is fixedly installed. One side of the inspection table 1 is fixedly connected through and provided with a cleaning seat 3. Above the cleaning seat 3, a sealing plate 4 is slidably fitted. Inside the cleaning seat 3, there is a moving seat 5. On the moving seat 5, a shooting mechanism 6 is fixedly connected. On the moving seat 5, an oral holding mechanism 7 is rotatably connected. One side of the bottom end of the cleaning seat 3 is fixedly connected with a liquid storage seat 8.

[0023] As Figure 4 shown, two pipe joints 301 are fixedly connected through the bottom end of the cleaning seat 3. One of the pipe joints 301 is fixedly connected with a flushing pipe 302 at one end located inside the cleaning seat 3. The two pipe joints 301 are respectively connected to an external clean water pipe and a sewage pipe through valves.

[0024] By setting the cleaning seat 3, after the oral cavity inspection is completed, the photographing mechanism 6 and the mouth holding mechanism 7 are automatically put into the cleaning seat 3, so as to realize the automatic flushing and soaking of the photographing mechanism 6 and the mouth holding mechanism 7. Automatic cleaning can fully flush and soak the equipment to ensure that each component can be thoroughly cleaned. Compared with manual cleaning, automatic cleaning can ensure more efficient and uniform cleaning effect, reduce dead corners, and at the same time reduce the workload of manual cleaning, reduce the labor intensity of operators, and improve work efficiency.

[0025] like Figure 5 As shown, a plurality of tension springs 401 are fixedly connected to one side of the sealing plate 4, and the other end of the tension spring 401 is fixedly connected to one side of the cleaning seat 3. A connecting rod group 402 is rotatably connected to the side of the sealing plate 4 connected to the tension spring 401, and the other end of the connecting rod group 402 is rotatably connected to the cleaning seat 3. The tension spring 401 realizes the automatic opening of the sealing plate 4.

[0026] One end of the connecting rod group 402 connected to the cleaning seat 3 is fixedly connected with a rotating shaft 403, and the bottom end of the rotating shaft 403 is fixedly connected with a transmission wheel 404. A transmission rack 405 is meshed and transmitted on one side of the transmission wheel 404. One end of the transmission rack 405 penetrates and slides with the inner wall of the cleaning seat 3. One end of the transmission rack 405 located in the cleaning seat 3 is fixedly connected with a trapezoidal block 406, and the trapezoidal block 406 is in sliding contact with the moving seat 5. The hydraulic rod 501 is used to drive the moving seat 5 to be retracted into the cleaning seat 3. When the moving seat 5 contacts the inclined surface of the trapezoidal block 406, the transmission rack 405 connected to the trapezoidal block 406 is pushed to move, so that the transmission rack 405 can drive the transmission wheel 404 to rotate. At this time, the transmission wheel 404 will drive the connecting rod group 402 connected to the rotating shaft 403 to rotate, thereby driving the sealing plate 4 to automatically reset and close.

[0028] like Figure 6As shown in the figure, the photographing mechanism 6 includes an electric push rod A601. One end of the electric push rod A601 is fixedly connected to the moving seat 5. The output end of the electric push rod A601 is fixedly connected to a moving rod 602. The other end of the moving rod 602 is rotatably connected to a rotating rod 603.

The other end of the rotating rod 603 is rotatably connected to an oral endoscope camera 605. Lighting tubes 606 are fixedly connected to the periphery of the rotating rod 603. The electric push rod A601 drives the connected moving rod 602 to move, so that the rotating rod 603 extends into the patient's mouth. Then, the motor 604 drives the rotating rod 603 to rotate. Cooperating with the lighting tubes 606 on the rotating rod 603, the oral endoscope camera 605 has an automatic focusing function, ensuring that the inside of the oral cavity can be accurately focused quickly at different distances and angles. According to different light conditions in the oral cavity, the oral endoscope camera 605 can automatically adjust the exposure and white balance to ensure the image quality.

[0029] As Figure 7 shown in the figure, the mouth holding mechanism 7 includes an electric push rod B701. The electric push rod B701 is fixedly connected to the moving seat 5. The output end of the electric push rod B701 is fixedly connected to a U-shaped rack 702. Two adjusting wheels 703 are symmetrically meshed and driven on both sides of the U-shaped rack 702. An adjusting rod 704 is fixedly connected to the adjusting wheel 703. One end of the adjusting rod 704 is rotatably connected to the moving seat 5. An adjusting frame 705 is rotatably connected between the two adjusting rods 704. A holding rod 706 is fixedly connected to the adjusting frame 705. The electric push rod B701 drives the connected U-shaped rack 702 to move, so that the U-shaped rack 702 can drive the adjusting wheel 703 to rotate, and the adjusting wheel 703 drives the connected adjusting rod 704 to rotate. At this time, the adjusting rod 704 drives the holding rod 706 on the adjusting frame 705 to move, and the two separated holding rods 706 support the patient's mouth.

[0030] As Figure 8 shown in the figure, a sealing cover 801 is threadedly connected to the top opening of the liquid storage seat 8. A liquid extraction pipe 802 is fixedly connected through the liquid storage seat 8. A temporary storage pipe 803 is fixedly connected to the liquid extraction pipe 802. A liquid discharge pipe 804 is fixedly connected through the temporary storage pipe 803. The other end of the liquid discharge pipe 804 is fixedly connected through the upper inner wall of the cleaning seat 3. One-way butterfly valves are installed in the liquid extraction pipe 802 and the liquid discharge pipe 804.

[0031] A piston 805 is slidably fitted to the inner wall of the temporary storage tube 803. One end of the piston 805 is fixedly connected to a spring 806, and the other end of the spring 806 is fixedly connected to the inner wall of the temporary storage tube 803. One end of the temporary storage tube 803 is penetrated and slidably fitted with a contact rod 807. One end of the contact rod 807 located inside the temporary storage tube 803 is fixedly connected to the piston 805, and the outer end of the contact rod 807 is movably in contact with one end of the transmission rack 405. When the transmission rack 405 moves, it will squeeze and drive the contact rod 807 to move, so that the contact rod 807 drives the connected piston 805 to move, thereby pumping out the cleaning liquid in the temporary storage tube 803 and injecting it into the cleaning base 3 through the drain pipe 804. Then the spring 806 drives the piston 805 to reset, and the cleaning liquid in the liquid storage base 8 is pumped into the temporary storage tube 803 through the liquid suction pipe 802.

[0032] Working principle: When it is necessary to examine the patient's oral cavity, first use the hydraulic rod 501 to drive the connected moving seat 5 to move upward, so that the mouth holding mechanism 7 moves out. Then the patient opens the mouth, and the upper and lower jaws are respectively located on one side of the two holding rods 706. Then use the electric push rod B701 to drive the connected U-shaped rack 702 to move, so that the U-shaped rack 702 can drive the adjusting wheel 703 to rotate, so that the adjusting wheel 703 drives the connected adjusting rod 704 to rotate. At this time, the adjusting rod 704 will drive the holding rod 706 on the adjusting frame 705 to move, and the two separated holding rods 706 support the patient's mouth to maintain a stable open state; Then use the electric push rod A601 to drive the connected moving rod 602 to move, so that the rotating rod 603 extends into the patient's mouth. Then use the motor 604 to drive the rotating rod 603 to rotate, and cooperate with the lighting tube 606 on the rotating rod 603, so that the oral endoscope camera 605 can automatically focus and shoot the picture in the oral cavity for analysis by the instrument main body 2; After the inspection is completed, use the hydraulic rod 501 to drive the moving seat 5 to retract into the cleaning base 3. When the moving seat 5 contacts the inclined surface of the trapezoidal block 406, it will push the transmission rack 405 connected to the trapezoidal block 406 to move, so that the transmission rack 405 can drive the transmission wheel 404 to rotate. At this time, the transmission wheel 404 will drive the connecting rod group 402 connected to the rotating shaft 403 to rotate, so as to drive the sealing plate 4 to automatically reset and close; At the same time, when the transmission rack 405 moves, it will squeeze and drive the contact rod 807 to move, so that the contact rod 807 drives the connected piston 805 to move, thereby pumping out the cleaning liquid in the temporary storage tube 803 and injecting it into the cleaning base 3 through the drain pipe 804. Then the spring 806 drives the piston 805 to reset, and the cleaning liquid in the liquid storage base 8 is pumped into the temporary storage tube 803 for temporary storage through the liquid suction pipe 802; Then, the external water source is ejected through the flushing pipe 302 to flush the photographing mechanism 6 and the mouth holding mechanism 7. At the same time, the water mixed with the cleaning liquid loaded into the cleaning seat 3 can soak and clean the internal structure, and then the cleaning water is discharged through another pipe joint 301.
