Description

Technical Field

[0001] The present invention relates to the technical field of handheld otoscopes, and in particular to a lens cleaning device for a handheld otoscope and a use method thereof. Background Art

[0002] An otoscope is a laparoscope used for examination or surgical evaluation of the external auditory canal, tympanic membrane, middle ear, etc. An otoscope can observe areas that are difficult to observe with a surgical microscope, such as the upper and posterior femoral chambers, so as to promptly detect middle ear lesions and reduce the recurrence rate of lesions. Its advantages are that it is non-invasive, has high resolution of images inside the ear, high lighting function, and high diagnostic rate. It allows clinical physicians to grasp specific subtle lesions inside the ear and provide timely treatment plans for patients. An otoscope can assist doctors in performing local infiltration anesthesia by dropping tetracaine into the ear.

[0003] The skin of the cartilaginous part of the external auditory canal has cerumen glands, whose light yellow and sticky secretions are called cerumen, commonly known as earwax. After drying in the air, cerumen becomes thin flakes; some cerumen is like sticky grease, commonly known as oily ears. Earwax has the function of protecting the skin of the external auditory canal and adhering foreign objects. The dirt on the otoscope is generally oily ears. General otoscope cleaning equipment needs to divide the otoscope into several parts for cleaning, and it is also necessary to replace disposable consumables, which increases cleaning time and usage costs and cannot meet actual needs.

[0047] A sliding cleaning mechanism is installed on the top of the mounting plate 3 , and the sliding cleaning mechanism is used to clean the lens 13 .

[0048] In this embodiment, the otoscope is composed of a frame 5, a handle 6, a lens 13 and a conical tube 18. After the otoscope is used, there is dirt inside the conical tube 18 and the lens 13 is not clear. By holding the handle 6, part of the conical tube 18 is inserted into the cleaning tube 17, and the handle 6 and the frame 5 are pressed to insert the conical tube 18 into the bottom of the cleaning tube 17.

[0049] Specifically, refer to Figure 1 , Figure 2 , Figure 3 and Figure 6 The rope winding mechanism includes a lifting tank 10 threadedly connected to the bottom end of the rotating rod 11, and two clamping plates 46 are fixedly connected to the inner bottom of the lifting tank 10. A rope wheel 48 is rotatably connected to one side of the clamping plate 46, and a spring piece 47 is provided at the connection between the rope wheel 48 and the clamping plate 46.

[0050] In this embodiment, when the cleaning rope 24 needs to be replaced, one end of the cleaning rope 24 on the rotating rod 11 is cut short, and the lifting tank 10 is pulled through the bottom circular hole of the base plate 1 so that the wedge block 19 is stuck in the cleaning groove 54, the position of the rotating rod 11 is fixed, and the lifting tank 10 is rotated to make the lifting tank 10 fall off the rotating rod 11.

[0052] In this embodiment, when cleaning begins, the edge of the cleaning tube 17 squeezes the block 36 through the squeezing guide rod 37 and the support spring 38, thereby stabilizing the cleaning tube 17. After use, the handle 6 is released, and the mirror frame 5 and the conical tube 18 will return to their original positions under the push of the guide rod 37 and the block 36, so that the sliding shell 4 is pushed back to its original position.

[0054] In this embodiment, the recovery bottle 12 recovers the cleaning liquid and dirt through the funnel 15 and the conduit 16 .

[0055] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 8 In a preferred embodiment, the rotating mechanism includes a rotating rod 11 slidably connected to the top of the fixed tank 9, one end of the rotating rod 11 is sleeved with a preload spring 23, one end of the rotating rod 11 is provided with a sliding notch 55, one end of the rotating rod 11 is provided with a cleaning notch 54 at a position below the sliding notch 55, a cleaning rope 24 is provided inside the rotating rod 11, and a lower magnet is provided at the top of the rotating rod 11;

[0056] A rope winding mechanism is installed at the bottom end of the rotating rod 11, and the rope winding mechanism is used to recover the cleaning rope 24. The sliding cleaning mechanism includes a long slide rail 40 fixedly connected to the top of the mounting plate 3, and a slide plate 41 is slidably connected inside the long slide rail 40. The upper surface of the slide plate 41 is fixedly connected to the sliding shell 4, and one end of the sliding shell 4 is fixedly connected to a rotating column 35. The bottom end of the rotating column 35 is provided with an upper magnet, and the top of the rotating column 35 is fixedly connected to a sponge 33. One end of the rotating column 35 is fixedly connected to a driven wheel 34, and the bottom of the inner wall of the sliding shell 4 is fixedly connected to a connecting column 42. One side of the connecting column 42 is fixedly connected to a motor 44, and one end of the output shaft of the motor 44 is a driving wheel 43, and a belt 45 is provided between the driving wheel 43 and the driven wheel 34.

[0057] A deflection spraying mechanism is installed inside the sliding shell 4, and the deflection spraying mechanism is used to spray the cleaning liquid.

[0058] In this embodiment, the rotating rod 11 extends into the interior of the conical tube 18 through the bottom of the conical tube 18, the sponge 33 contacts the surface of the lens 13, and the upper magnet at the bottom of the rotating column 35 is adsorbed together with the lower magnet at the top of the rotating rod 11. The motor 44 drives the driving wheel 43, the belt 45 and the driven wheel 34 to rotate, thereby driving the rotating column 35 to rotate, so that the sponge 33 rotates to continuously wipe the surface of the lens 13 and remove dirt on the surface of the lens 13. Before use, spray a medical alcohol solution on the sponge 33 to clean the lens 13.

[0059] It is also necessary to explain that in order to prevent the rotation of the rotating rod 11 from tightening the cleaning rope 24 and thus affecting the cleaning effect, the rotation direction of the rotating rod 11 is controlled by controlling the rotation direction of the motor 44, so that after the rotating rod 11 rotates a certain number of times, the rotation direction is changed and reversed, and this cycle is repeated to ensure that the cleaning rope 24 will not affect the cleaning effect due to being tightened.

[0060] Furthermore, the rotation of the rotating column 35 also drives the rotating rod 11 and the lifting tank 10 to rotate. Since the cleaning rope 24 can slide inside the rotating rod 11, the rotating rod 11 drives the cleaning rope 24 to rotate, and a part of the cleaning rope 24 is exposed outside. Due to the action of centrifugal force, the cleaning rope 24 slides inside the rotating rod 11, and the cleaning rope 24 will be thrown onto the inner wall of the conical cylinder 18. The centrifugal force rotates the pulley 48 and twists the spring piece 47 to make the cleaning rope 24 slide out from the inside of the rotating rod 11. The cleaning rope 24 rotates inside the conical cylinder 18 to break the dirt attached to the inner wall of the conical cylinder 18, so that it falls from the conical cylinder 18 and falls to the bottom of the conical cylinder 18, thereby cleaning the dirt inside the conical cylinder 18. The otoscope can be reused without the need to replace disposable consumables, which shortens the time for cleaning the otoscope, reduces the use of disposable consumable parts, and reduces costs.

[0061] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 In a preferred embodiment, the liquid delivery mechanism includes a cleaning liquid bottle 2 fixedly connected to the top of the mounting frame 8, a water pump 25 is fixedly connected to the upper surface of the mounting frame 8, a water inlet pipe 26 is plugged into one side of the water pump 25, and a water outlet pipe 27 is plugged into the upper surface of the water pump 25, and the deflection spraying mechanism includes a fixed plate fixedly connected to the inner wall of the bottom of the sliding shell 4, a spraying block 53 is rotatably connected to one side of the fixed plate, a spraying channel 51 is arranged inside the spraying block 53, an auxiliary block 49 is fixedly connected to the top edge of the fixed plate, and a rotation spring 50 is fixedly connected to the bottom of the auxiliary block 49;

[0062] A linkage mechanism is installed on the upper surface of the mounting frame 8 , and the linkage mechanism is used to realize automatic sliding of the sliding shell 4 .

[0063] In this embodiment, the spray block 53 is squeezed by the pressure block 39, and the spray block 53 is located inside the sliding shell 4, squeezing the rotation spring 50. When the spray block 53 is separated from the pressure block 39, the rotation spring 50 pushes the spray block 53 to rotate, and one end of the spray channel 51 faces the inside of the conical cylinder 18.

[0064] Furthermore, the cleaning liquid in the cleaning liquid bottle 2 is pumped out through the water inlet pipe 26, and the cleaning liquid is transmitted to the inside of the spray block 53 through the water outlet pipe 27, and the cleaning liquid is sprayed into the inside of the conical tube 18 through the spray block 53. The cleaning liquid is composed of an organic solvent, and most of the dirt inside the conical tube 18 is earwax, and the components of earwax are protein and fatty acids. The cleaning liquid can dissolve protein and fatty acids, making it easier to clean the dirt at the bottom of the conical tube 18 without residue.

[0065] It is also necessary to explain that the cleaning rope 24 can be soaked in cleaning liquid to increase the mass of the cleaning rope 24, increase the centrifugal force, and make it easier for the cleaning rope 24 to slide out. The surface tension of the liquid can also increase the toughness of the cleaning rope 24 and prevent the cleaning rope 24 from breaking during rotation.

[0066] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4In a preferred embodiment, the extrusion mechanism includes a wedge block 19 fixedly connected to the bottom of the cleaning cylinder 17, the upper surface of the mounting frame 8 is located below the wedge block 19 and is fixedly connected to a sliding block 21, the bottom of the sliding block 21 is slidably connected to a short slide rail 20, and one end of the short slide rail 20 is fixedly connected to an extrusion spring 22, and the linkage mechanism includes a mounting plate 14 fixedly connected to the upper surface of the mounting frame 8 and located directly below the sliding shell 4, one side of the mounting plate 14 is rotatably connected to a second gear 30, one side of the mounting plate 14 is rotatably connected to a position close to the second gear 30, and one side of the mounting plate 14 is rotatably connected to a position close to the second gear 30. A first gear 32 is rotatably connected to a position close to the middle gear 31 of the mounting plate 14, the second gear 30 is meshed with the middle gear 31, and the middle gear 31 is meshed with the first gear 32, a first rack 28 is fixedly connected to the bottom of the sliding shell 4, a second rack 29 is fixedly connected to one side of the cleaning cylinder 17, the second rack 29 is meshed with the second gear 30, and the first rack 28 is meshed with the first gear 32.

[0067] In this embodiment, due to the downward squeezing of the conical cylinder 18, the second rack 29 drives the second gear 30 to rotate, thereby driving the intermediate gear 31 and the first gear 32 to rotate. The intermediate gear 31 plays a reversing role, and the first gear 32 drives the first rack 28 to slide to the left, so that the sliding shell 4 extends into the interior of the frame 5 to clean the lens 13.

[0068] Working principle: The otoscope is composed of a frame 5, a handle 6, a lens 13 and a conical tube 18. After the otoscope is used, there is dirt inside the conical tube 18 and the lens 13 is not clear. By holding the handle 6, part of the conical tube 18 is inserted into the cleaning tube 17, and the handle 6 and the frame 5 are pressed to insert the conical tube 18 into the bottom of the cleaning tube 17. At this time, the edge of the cleaning tube 17 squeezes the block 36 through the squeezing guide rod 37 and the support spring 38 to move downward under force, and the rotating rod 11 passes through the bottom of the conical tube 18 and extends into the conical tube 18. Since the conical tube 18 The second rack 29 is pressed downward, so that the second gear 30 is driven to rotate, thereby driving the intermediate gear 31 and the first gear 32 to rotate. The intermediate gear 31 plays a reversing role. The first gear 32 drives the first rack 28 to slide leftward, so that the sliding shell 4 extends into the interior of the frame 5. The sponge 33 contacts the surface of the lens 13. The upper magnet at the bottom of the rotating column 35 is adsorbed with the lower magnet at the top of the rotating rod 11. Due to the squeezing of the pressing block 39, the spraying block 53 is located inside the sliding shell 4, squeezing the rotating spring 50. When the spraying block 53 is separated from the pressing block 39,The rotating spring 50 pushes the spray block 53 to rotate, and one end of the spray channel 51 faces the inside of the conical cylinder 18. The motor 44 drives the driving wheel 43, the belt 45 and the driven wheel 34 to rotate, thereby driving the rotating column 35 to rotate, so that the sponge 33 rotates to continuously wipe the surface of the lens 13 to remove the dirt on the surface of the lens 13. Before use, spray a medical alcohol solution on the sponge 33 to clean the lens 13. The rotation of the rotating column 35 also drives the rotating rod 11 and the lifting tank 10 to rotate. Since the cleaning rope 24 can slide inside the rotating rod 11, The rotating rod 11 drives the cleaning rope 24 to rotate, and a part of the cleaning rope 24 is exposed outside. Due to the effect of centrifugal force, the cleaning rope 24 slides inside the rotating rod 11, and the cleaning rope 24 is thrown onto the inner wall of the conical cylinder 18. The centrifugal force rotates the rope wheel 48, twists the spring piece 47, and makes the cleaning rope 24 slide out from the inside of the rotating rod 11. The cleaning rope 24 rotates inside the conical cylinder 18, and the dirt attached to the inner wall of the conical cylinder 18 is broken, so that it falls from the conical cylinder 18 and falls on the bottom of the conical cylinder 18, which plays a role in cleaning the dirt inside the conical cylinder 18. At the same time, the water pump 25 is turned on to extract the cleaning liquid in the cleaning liquid bottle 2 through the water inlet pipe 26, and the cleaning liquid is transmitted to the inside of the spray block 53 through the water outlet pipe 27. The cleaning liquid is sprayed into the inside of the conical tube 18 through the spray block 53. The cleaning liquid is composed of an organic solvent. Most of the dirt inside the conical tube 18 is earwax. The components of earwax are protein and fatty acids. The cleaning liquid can dissolve protein and fatty acids, making it easier to clean the dirt at the bottom of the conical tube 18 without residue. The handle 6 is released by hand, and the frame 5 and the conical tube 18 will be on the guide rod 37 and the block 36. Under the push of the , the otoscope returns to its original position, so that the sliding shell 4 is pushed back to its original position. The otoscope can be reused, and there is no need to replace disposable consumables, which shortens the time for cleaning the otoscope, reduces the use of disposable consumable parts, and reduces costs.
