Description

Technical Field

[0001] This invention relates to the field of medical devices, and specifically provides a medical dental endoscope. Background Technology

[0002] During dental examinations and treatments, dental professionals typically use dental mirrors to assist in observing the patient's oral cavity for diagnosis and treatment. However, current dental mirrors have several shortcomings. For example, they are fixed in structure, cannot be adjusted in angle, are difficult to adapt to different patient groups, and are prone to fogging, which can hinder the dentist's observation.

[0003] Existing technologies offer certain solutions, such as patent US10426329B2, which provides a multi-purpose self-illuminating dental endoscope composed of three detachable components. The first component includes multiple light sources, the second component includes a handle that powers the first light source, and the third component includes a laser pointer, etc., achieving the technical effect of illuminating the inside of the patient's mouth from multiple angles, allowing doctors to observe the condition inside the patient's mouth more clearly. However, this dental endoscope fails to solve the problem of the lens easily fogging up, and the inventor believes that there is still much room for improvement. Summary of the Invention

[0004] To address the aforementioned lens fogging problem and facilitate medication application, this invention provides a medical dental endoscope. The endoscope includes a housing with a rotating shaft rotatably connected to its end. A first column is connected to one side of the rotating shaft, and an arc-shaped groove is formed on the surface of the first column for placing a lens. The endoscope is characterized by a flow guiding assembly within the housing, comprising a flow guiding base with a central opening and multiple flow guiding grooves on its sides, and a first groove for fixing the lens on one side.

[0005] Furthermore, the lens is mainly cylindrical, with a groove on one side. A convex lens is placed in the groove, which can magnify the object, allowing doctors to observe the lesion area more clearly. At the same time, the radius of the lens is slightly larger than the inner diameter of the outer support, which helps the lens to be firmly fixed in the groove, preventing it from loosening during use and being swallowed by the patient.

[0006] In this invention, a connecting strip is provided at one end of the first column, a portion of which is located inside the housing. An illumination component is fixedly connected to the end of the first column away from the connecting strip, and the illumination component is arranged parallel to the lens.

[0007] Furthermore, the lighting component is located at the bottom of the lens and includes bulbs symmetrically placed on the left and right sides, which can maximize the lighting range. Since the lens uses a convex lens, placing the lighting component at the bottom can effectively prevent the light from focusing on the convex lens.

[0008] In this invention, a fixed base is fixedly connected to the side of the shell near the first column. A through hole is opened in the center of the fixed base, and a water supply pipe is installed at the through hole. One end of the water supply pipe is fixedly connected to the flow guide base. A medicine delivery component is fixedly connected to the bottom of the shell, and a button is provided on one side of the shell.

[0009] In this invention, the flow guide base is provided with threads below, a sleeve is fitted on one end of the flow guide base, a rotating column is abutted on one end of the sleeve, a base is fixedly connected to one end of the rotating column, a second groove is provided in the middle of the rotating column, a third groove is provided on the surface of the base, and a flow guide shell is fitted on the outside of the base.

[0010] Furthermore, when the lens fogs up, the airflow guide assembly is activated to remove the fog. A vibration motor controls the rotation of the chassis within the airflow guide assembly. When the motor operates, a plate beneath the chassis rotates relative to the airflow guide housing, causing the chassis to rotate and consequently rotating the rotating column. Water flows into the water supply pipe from the outside. As the water flows into the rotating column, the rotating column creates a swirling current that is sprayed from the outlet pipe onto the lens surface, effectively rinsing the lens and thus resolving the fogging problem.

[0011] In this invention, the side of the flow guide shell is provided with multiple threaded holes, and fixing bolts are installed on the threaded holes. The chassis can rotate relative to the flow guide shell, and a water supply pipe is fixedly connected to the center of the chassis. The end face of the flow guide base and the end face of the flow guide shell are on the same plane.

[0012] In this invention, a fixing ring is provided inside the shell, which is used in conjunction with the water supply pipe, and the guide shell does not contact the inner wall of the shell.

[0013] Furthermore, because the rotating column abuts against the sleeve, in actual operation, water flows into the device, and the sleeve rotates under the action of the rotating column. The guide body and the sleeve are connected by threads, and the rotation of the rotating column causes the guide body to rotate as well. Since the top of the guide shell has a cone-like structure, the outlet portion of the guide shell can securely hold the top of the guide body, causing the sleeve to rotate and the guide body to move upwards and downwards. A portion of the bolt is fitted into the first groove, ensuring the range of motion of the guide body and preventing it from rotating and detaching from the device. When the guide body moves upwards, the guide groove expands and opens, allowing some water to flow outwards, reducing the pressure of the outflowing water. This results in a smaller impact force in the swirling stream sprayed from the outlet pipe, preventing water hitting the lens from splashing into the patient's throat and causing choking. Furthermore, when the guide body retracts and moves downward, the opening of the guide channel narrows, which reduces the radius of the water flow through the pipe and increases the water pressure. This causes the water retained around the guide channel to spray out of the pipe, preventing too much water from remaining inside the pipe and extending the service life of the device.

[0014] In this invention, the drug delivery assembly includes a drug placement plate, which is semi-circular with one end cut and having an opening. A connector is fixedly connected to the end of the drug placement plate away from the opening. A first base is fitted onto the bottom of the connector. A support plate is fixedly connected to the bottom of the first base. A stabilizing component is fixedly connected to one side of the support plate. A second base is connected to one end of the stabilizing component. An end cap is provided at one end of the second base. A vibration motor is provided on one side of the second base and is located inside the housing.

[0015] Furthermore, during operation, the device requires manual placement of the medication onto the drug-dispensing plate, followed by pressing a button to activate the vibration motor. Vibration then propels the medication through a notch on the side of the drug-dispensing plate to the patient's lesion area. Specifically, a connector at the bottom of the drug-dispensing plate is partially embedded in the first base. The connector's bottom is a spherical structure that can rotate relative to the first base, further expanding the medication delivery area. An end cap at the bottom of the delivery assembly enhances the tightness of the connection between the internal stabilizing components, the second base, and the first base.

[0016] In this invention, the stabilizing component includes: a stabilizing outer shell, with small holes for connection at both ends of the stabilizing outer shell, and a partition inside the stabilizing outer shell, which divides the internal space into arc-shaped, spherical, and fan-shaped areas, with rollers provided in the spherical area.

[0017] The stabilizing component is located at one end of the bottom support plate of the first component, while the other end of the stabilizing component is fixedly connected to the second base, which can effectively transmit vibration. The hollow area separated by the partition inside the stabilizing component can provide good shock absorption, which can control the impact force provided by the vibration motor within a reasonable range. At the same time, the roller can impact the walls of the surrounding partitions during vibration, reducing some of the impact force, which can further improve the connection strength inside the device, prevent the device from loosening inside during operation, and ensure that the entire drug delivery component is subjected to uniform force. This prevents the drug from spilling out or failing to accurately fall to the lesion area due to excessive vibration on the side near the motor.

[0018] Compared with existing technologies, the advantages of this invention are as follows: This invention can illuminate the patient's oral cavity, allowing doctors to observe the patient's oral condition more clearly. A water outlet pipe and a flow guiding component are installed behind the lens to ensure that fogging is removed when the lens fogs up, while also preventing the patient from being choked by the sprayed water. A medication delivery component is located at the bottom of the device. This component uses a vibration motor to deliver medication to the affected area, and the vibration motor also shakes off any remaining water droplets on the lens. Attached Figure Description

Detailed Implementation

[0021] Example 1: Reference Appendix Figure 1 , Figure 2 , Figure 3 As shown, the present invention provides a medical dental endoscope. The dental endoscope includes a housing 30, a rotating shaft 12 rotatably connected to one end of the housing 30, a first column 11 connected to one side of the rotating shaft 12, and an arc-shaped groove on the surface of the first column 11 for placing a lens 10. The feature is that a flow guiding assembly 22 is provided inside the housing 30. The flow guiding assembly 22 includes a flow guiding base 23, which has a central opening and multiple flow guiding grooves 231 on its side. A first groove 232 for fixing is provided on one side of the flow guiding base 23.

[0022] Furthermore, the lens 10 is mainly cylindrical, with a groove on one side. A convex lens is placed in the groove, which can magnify the object, allowing the doctor to observe the lesion area more clearly. At the same time, the radius of the lens 10 is slightly larger than the inner diameter of the outer support, which helps the lens 10 to be firmly fixed in the groove, preventing it from loosening during use and being swallowed by the patient.

[0023] In this invention, a connecting strip 14 is provided at one end of the first column 11, a portion of which is located inside the housing 30. An illumination component 13 is fixedly connected to the end of the first column 11 away from the connecting strip 14, and the illumination component 13 is arranged parallel to the lens 10.

[0024] Furthermore, the lighting component 13 is located at the bottom of the lens 10. The lighting component 13 includes bulbs symmetrically placed on the left and right sides, which can maximize the lighting range. Since the lens 10 uses a convex lens, placing the lighting component 13 at the bottom can effectively prevent the light from focusing on the convex lens.

[0025] In this invention, a fixed base 20 is fixedly connected to the side of the housing 30 near the first column 11. A through hole is opened in the center of the fixed base 20, and a water supply pipe 21 is installed at the through hole. One end of the water supply pipe 21 is fixedly connected to a flow guide base 23. A medicine delivery component 40 is fixedly connected to the bottom of the housing 30, and a button 31 is provided on one side of the housing 30.

[0026] Reference Appendix Figure 3 , Figure 4 , Figure 5 As shown, in this invention, the flow guide base 23 is provided with a thread 233 below, a sleeve 24 is sleeved on one end of the flow guide base 23, a rotating column 26 is abutted on one end of the sleeve 24, a base 27 is fixedly connected to one end of the rotating column 26, a second groove 261 is provided in the middle of the rotating column 26, a third groove 271 is provided on the surface of the base 27, and a flow guide shell 25 is sleeved on the outside of the base 27.

[0027] Furthermore, when the lens 10 fogs up, the flow guide assembly 22 needs to be activated to remove the fog from the lens 10. The vibration motor 49 can control the rotation of the chassis 27 in the flow guide assembly 22. When the vibration motor 49 is working, the plate provided below the chassis 27 can rotate relative to the flow guide housing 25, driving the chassis 27 to rotate and thus driving the rotating column 26 to rotate. Water flows from the outside into the water supply pipe 50. When the water flows into the rotating column 26, the rotating column 26 can form a vortex that is sprayed out from the water outlet pipe 21 onto the surface of the lens 10, achieving the effect of rinsing the lens surface, thereby solving the problem of fogging of the lens 10.

[0028] In this invention, the side of the flow guide shell 25 is provided with multiple threaded holes, and fixing bolts 251 are installed on the threaded holes. The base 27 can rotate relative to the flow guide shell 25. A water supply pipe 50 is fixedly connected to the center of the base 27. The end face of the flow guide base 23 and the end face of the flow guide shell 25 are on the same plane.

[0029] In this invention, a fixing ring 51 is provided inside the housing 30. The fixing ring 51 is used in conjunction with the water supply pipe 50, and the guide shell 25 does not contact the inner wall of the housing 30.

[0030] Reference Appendix Figure 4 , Figure 5 As shown, further, since the rotating column 26 abuts against the sleeve 24, in actual operation, water flows into the device, and the sleeve 24 rotates under the action of the rotating column 26. The guide body 23 and the sleeve 24 are connected by a thread, and the rotation of the rotating column 26 causes the guide body 23 to also rotate. Because the top of the guide shell 25 has a cone-like structure, the outlet portion of the guide shell 25 can securely hold the top of the guide body 23, causing the sleeve 24 to rotate and the guide body 23 to move upwards and downwards. A portion of the bolt 251 is fitted inside the first groove 232, which ensures the range of motion of the guide body 23 and also prevents the guide body 23 from rotating and detaching from the device. When the guide body 23 moves upwards, the guide groove 231 expands and opens, allowing some water to flow outwards, reducing the pressure of the outflowing water. This results in a smaller impact force on the swirling stream sprayed from the outlet pipe 21, preventing water hitting the lens 10 from splashing into the patient's throat and causing choking. Furthermore, when the guide body 23 retracts and moves downward, the opening of the guide channel 231 shrinks, which reduces the radius of the water flow through the pipe and increases the water pressure. This causes the water trapped around the guide channel 231 to spray out of the pipe, preventing too much water from remaining inside the pipe and extending the service life of the device.

[0031] Example 2: The difference between this embodiment and Embodiment 1 is that, with reference to Appendix Figure 3 , Figure 6 As shown, in this invention, the drug delivery assembly 40 includes a drug placement plate 41, which is semi-circular with one end cut and has an opening. A connector 42 is fixedly connected to the end of the drug placement plate 41 away from the opening. A first base 43 is sleeved on the bottom of the connector 42. A support plate 45 is fixedly connected to the bottom of the first base 43. A stabilizing component 46 is fixedly connected to one side of the support plate 45. A second base 47 is connected to one end of the stabilizing component 46. An end cap 48 is provided at one end of the second base 47. A vibration motor 49 is provided on one side of the second base 47. The vibration motor 49 is located inside the housing 30.

[0032] Furthermore, during operation, the device requires manual placement of the medication onto the drug-dispensing plate 41, followed by pressing button 31 to activate the vibration motor 29. Vibration causes the medication to slide from the notch on the side of the drug-dispensing plate 41 into the patient's lesion area. Specifically, a portion of the connector 42 at the bottom of the drug-dispensing plate 41 is embedded in the first base 43. The bottom of the connector 42 has a spherical structure that allows it to rotate relative to the first base 43, further expanding the medication delivery area of ​​the drug-dispensing plate 41. The end cap 48 at the bottom of the medication delivery assembly 40 enhances the tightness of the connection between the internal stabilizing assembly 46, the second base 47, and the first base 43.

[0033] Reference Appendix Figure 7As shown, in this invention, the stabilizing component 46 includes: a stabilizing housing 461, with small holes for connection at both ends of the stabilizing housing 461, and a partition 462 inside the stabilizing housing 461, which divides the internal space into arc-shaped, spherical and fan-shaped areas, with rollers 463 provided in the spherical area.

[0034] The stabilizing component 46 is located at one end of the bottom support plate 45 of the first component 43, and the other end of the stabilizing component 46 is fixedly connected to the second base 47, which can effectively transmit vibration. The hollow area inside the stabilizing component 46, which is separated by the partition plate 462, can effectively absorb shock and control the impact force provided by the vibration motor 29 within a reasonable range. At the same time, the roller 463 can impact the walls of the surrounding partition plate 462 when vibrating, reducing some of the impact force and further improving the internal connection strength of the device. This prevents the device from becoming loose during operation, ensuring that the entire drug delivery component 40 is subjected to uniform force. It also prevents the drug from spilling out of the drug delivery plate 41 or failing to accurately fall into the lesion area due to excessive vibration on the side near the motor.

[0035] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept, and these all fall within the scope of protection of the invention. Therefore, the scope of protection of this invention patent should be determined by the appended claims.
