The high-definition camera integrated at the end captures the oral cavity picture in cooperation with the illumination, and the data transmission system displays the picture on the display in real time. The suction / washing system is responsible for oral cavity flushing and waste liquid recovery.

[0012] Preferably, the groove surface of the helical groove is a smooth surface, the outer surface of the sliding convex column is also a smooth surface, and the lead of the helical groove is matched with the rotation angle of the sector gear.

[0013] Preferably, the sliding convex column is initially located in the middle of the helical groove, when the sliding convex column translates towards the sector gear, the helical groove guides the sector gear to rotate 45 degrees in the positive direction, and vice versa, the outer walls on both sides of the sector gear are symmetrically fixedly provided with limiting hole plates, and the limiting hole plates are provided with circular holes for the translation of the adaptive push rod.

[0015] Compared with the known prior art, the technical scheme provided by the application has the following beneficial effects: The medical oral cavity observation instrument with automatic flushing function, medical staff drives the independent deflection of the right-angle pipe by pushing the arc-shaped push piece, so that the flushing angle adjustment does not need to move the observation instrument main body and the camera module.

Medical staff can adjust the direction of the right-angle pipe and the tooth or gum by operating the unilateral push piece, and can drive the right-angle pipes on both sides to form an angle of opposite flushing flow by synchronously pushing the bilateral push pieces, so that the intersection impact force of the water flow is used to clean the parts such as the occlusal surface of the tooth and the papilla area of the gum where residues are easy to accumulate, and the flushing accuracy in the oral cavity flushing process is improved. In addition, since the medical staff does not need to move the instrument greatly, the adjustment of the flushing angle can be completed by only slightly pushing or pulling the arc-shaped push piece, the design that the arc-shaped push piece is matched with the outer contour of the observation instrument main body makes the operation process more in line with the natural hand holding posture, and the reset function of the clock spring further simplifies the operation steps of the angle adjustment, effectively reduces the operation strength of the medical staff in the long-time diagnosis and treatment process, and improves the operation convenience. In addition, electric adjustment can also be realized through a micro electric control telescopic rod, and the medical staff only needs to control the piston rod to extend or retract through the handle button or switch, without manual adjustment. The steps of force control and direction calibration during manual adjustment are saved, and the operation convenience is improved. BRIEF DESCRIPTION OF DRAWINGS

[0018] The present invention will be further described below with reference to embodiments.

[0019] Example 1: like Figures 1 to 8 As shown, a medical oral observation instrument equipped with an automatic rinsing function includes an observation instrument body 1. A camera module 11 is provided at one end of the observation instrument body 1. Pump water pipes 12 are symmetrically arranged on both sides of the observation instrument body 1. At least two pump water pipes 12 are provided and are respectively inserted through the side of the observation instrument body 1. The two ends of the pump water pipes 12 extend to the outside of the observation instrument body 1.

[0020] An external water pumping system is provided, with its pump outlet connected to the end of the water pumping pipe 12 away from the camera module 11. The external water pumping system includes a control unit and a supply device. The control unit is used to turn the supply device on and off and to adjust the pumping pressure of the supply device. Specifically, the control unit and the supply device are respectively configured as a controller and a water pump. The water pump's pumping end is connected to an external water supply system, such as a container filled with pure water, and its outlet end is connected to the end of the water pumping pipe 12 away from the camera module 11.

[0021] It also includes an active adjustment mechanism, which includes a combination housing 21 symmetrically fixed on both sides of the main body 1 of the observation instrument. Both combination housings 21 are located on the side closer to the camera module 11. The interior of the side of the two combination housings 21 away from the main body 1 of the observation instrument is rotatably connected to a connecting tube 22, and both ends of the connecting tube 22 extend to the outside of the combination housing 21. A right-angle tube 23 is inserted into the side of the connecting tube 22 closer to the camera module 11. The middle axis of the vertical part of the right-angle pipe 23 is horizontal with the middle axis of the camera module 11, that is, the shooting end of the camera module 11 is horizontal with the water outlet end of the right-angle pipe 23, ensuring the coordination of the flushing area and the observation field of view. The annular gear 24 is fixedly installed on the outer peripheral surface of the communicating rotary pipe 22 inside the combined shell 21, the inside of the combined shell 21 is further rotationally connected with the sector gear 25 engaged with the annular gear 24, the sector gear 25 is connected with the part rotationally connected with the combined shell 21 with the clock spring 26, one end of the clock spring 26 is fixed with the outer wall of the part rotationally connected with the combined shell 21, and the other end is fixed with the inner wall of the combined shell 21. The co-axial cylinder 27 is fixedly connected with the part rotationally connected with the combined shell 21, wherein the co-axial cylinder 27 is located away from the right-angle pipe 23. The co-axial cylinder 27 is provided with the spiral groove 271 on the outer peripheral surface, and the co-axial rod 28 is movably inserted into the co-axial cylinder 27. The end of the co-axial rod 28 close to the co-axial cylinder 27 is fixedly provided with the sliding convex column 281, the sliding convex column 281 is slidably arranged in the spiral groove 271, the groove surface of the spiral groove 271 is smooth, and the outer surface of the sliding convex column 281 is also smooth, which reduces the friction when the two are slidably connected and ensures the smoothness of the sliding connection. The lead of the spiral groove 271 is adapted to the rotation angle of the sector gear 25. The co-axial rod 28 is fixedly connected with the adaptive push rod 29 at the end away from the co-axial cylinder 27, and the adaptive push rod 29 is fixedly provided with the arc-shaped push piece 210 at the end away from the co-axial rod 28. The shape of the adaptive push rod 29 and the arc-shaped push piece 210 is adapted to the outer contour shape of the observation instrument main body 1, wherein the outer surface of the arc-shaped push piece 210 is provided with a soft rubber layer, and the soft rubber layer is a rubber pad with anti-slip patterns.

[0022] Further, the combined shell 21 is composed of two half shells, one of which is fixedly connected with the outer wall of the observation instrument main body 1, and the other is tightly clamped and connected with the half shell. Specifically, the two half shells are respectively provided with convex strips and concave grooves on the sides close to each other, and are clamped and connected through the convex strips and the concave grooves. The split structure of the two half shells facilitates the assembly of internal parts. If the internal parts are worn or malfunctioning, the clamped and connected half shells can be separated for repair or replacement, simplifying the assembly process and maintenance operation.

[0023] Further, the right-angle pipe 23 is made of silica gel material, and the top of the right-angle pipe 23 is provided with a trumpet-shaped flared part. The silica gel material of the right-angle pipe 23 is convenient to insert into the communicating rotary pipe 22, and the flared part is beneficial to expand the flushing range.

[0024] Further, the sliding convex column 281 is initially located in the middle of the spiral groove 271, and when the sliding convex column 281 translates towards the sector gear 25, the spiral groove 271 guides the sector gear 25 to rotate forward by 45°. Conversely, the sector gear 25 rotates reversely by 45°.

[0025] Further, the two side walls of the observation instrument body 1 are symmetrically provided with limiting hole plates 291, and the limiting hole plates 291 are each provided with a circular hole for the translation of the adaptive push rod 29. The circular hole of the limiting hole plate 291 is used to ensure the stability of the translation of the adaptive push rod 29.

[0026] In use: after the observation instrument is sterilized, the medical staff holds the observation instrument body 1, and the camera module 11 and the right-angle tube 23 are inserted into the oral cavity of the patient. During the process, the medical staff can observe the situation in the oral cavity of the patient through the display. The external water pump system is connected to the pure water container, and the preset flushing pressure is controlled by the control unit.

[0027] When the medical staff needs to flush the teeth, the arc-shaped push piece 210 on one side is pushed or pulled back, which drives the adaptive push rod 29 and the coaxial rod 28 to translate, promotes the sliding protrusion 281 to slide along the spiral groove 271, and thus promotes the driving coaxial cylinder 27, the sector gear 25, and the ring gear 24 to rotate, so that the corresponding side of the communicating rotating tube 22 drives the right-angle tube 23 to deflect (maximum 45°). At this time, the opposite right-angle tube 23 remains in the initial vertical state because the opposite push piece is not pushed, and the clockwork spring 26 is not stressed, so that the “one-side flushing” is realized.

[0028] If the double-side water flow is needed to be clamped and flushed, the medical staff synchronously pushes the arc-shaped push pieces 210 on both sides of the oral cavity, which links the two sides of the sector gear 25 and the ring gear 24, so that the two sides of the right-angle tube 23 deflect towards each other (each rotates by 45°, and the included angle is 90°), and the “opposite flushing flow” is formed. The flushing liquid is sprayed from the two sides of the right-angle tube 23, and is converged on the surface of the teeth / gums. The food residues and soft dirt are stripped by the water flow impact force.

[0029] Example Two: As shown in Figure 9 the above-mentioned medical oral cavity observation instrument with an automatic flushing function further comprises an automatic driving device for replacing the adaptive push rod 29 and the arc-shaped push piece 210 in the above-mentioned example one, so as to automatically adjust the rotation angle of the right-angle tube 23. Specifically, the automatic driving device is configured as: two micro electric control telescopic rods which are symmetrically installed on the two side walls of the observation instrument body 1. The micro electric control telescopic rod is controlled by an external controller to control the opening and closing and the telescopic distance of the piston rod. The end of the piston rod of the micro electric control telescopic rod is fixedly connected with the coaxial rod 28, and the telescopic movement of the piston rod drives the coaxial rod 28 to move synchronously.

[0030] In use: the flushing start key is pressed, the external water pump system starts to supply water, and at the same time, the piston rod of the electric control telescopic rod is telescoped, which pushes the coaxial rod 28 to translate, drives the sliding protrusion 281 to drive the coaxial cylinder 27 to rotate along the spiral groove 271, links the sector gear 25, the ring gear 24, and the communicating rotating tube 22 to rotate, and adjusts the angle of the right-angle tube 23. During the adjustment process, the camera module 11 feeds back the oral cavity field of view in real time, and the medical staff can adjust the angle through the keys.

[0031] The above examples are only used to illustrate the technical solutions of the present application, but not to limit the present application; although the present application has been described in detail with reference to the foregoing examples, those ordinarily skilled in the art should understand: the technical solutions recorded in the foregoing examples can still be modified, or some technical features can be replaced equivalently; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
