Description

Technical Field

[0001] The utility model relates to the technical field of ear canal treatment, in particular to an ear canal dilator. Background Art

[0002] During ear canal examination and treatment, an ear canal dilator is often used to dilate the ear canal to provide medical staff with a clear view. Currently, most ear canal dilators on the market require medical staff to operate them manually. This not only limits the use of medical staff's hands, affecting treatment effectiveness, but also results in a waste of human resources when two people are required to operate them together.

[0003] Although an ear canal dilator (Chinese Patent Application No. 202321391017.5) is currently available in the art, it secures the dilator to the patient's head via a wearable fastener, enabling the dilator to be operated without the need for medical personnel to hold the patient's hand. This innovation significantly improves the convenience and efficiency of treatment. However, this ear canal dilator still has some shortcomings in practical application.

[0004] The main problem is that the existing wearable fixtures are relatively bulky in design, which not only increases the cost of manufacturing materials, but also takes up a large space during transportation and storage, causing inconvenience to users. In addition, the bulky wearable fixtures may also cause a certain degree of discomfort to patients, affecting their user experience. Therefore, how to reduce the size of the wearable fixtures while maintaining the function of the ear canal expander and improve the convenience and comfort of use has become an important challenge facing the current ear canal expander technology. This utility model patent is based on this demand and is committed to developing an ear canal expander that is smaller and more convenient to use to meet the actual needs during ear canal examination and treatment.

[0005] The embodiment of the present invention provides an ear canal dilator to solve the problems in the prior art.

[0006] An embodiment of the present utility model adopts the following technical solution: an ear canal expander, including a mounting shell, to which an ear hook is fixedly connected, an observation port penetrating the mounting shell is provided inside the mounting shell, a first ear-expanding arc plate and a second ear-expanding arc plate are arranged opposite to each other in the observation port, and an ear-expanding mechanism is provided inside the mounting shell to drive the first ear-expanding arc plate and the second ear-expanding arc plate to move relative to each other.

[0007] Preferably, the outer surface of the ear hook is provided with anti-slip grooves, the end of the ear hook away from the mounting shell is fixedly connected to a counterweight block, the outer surface of the first ear-expanding arc plate is pasted with a first arc-shaped cushion, and the outer surface of the second ear-expanding arc plate is pasted with a second arc-shaped cushion.

[0008] Preferably, the ear expansion mechanism includes a slide groove, a bidirectional screw rod, and a fixed plate. The slide groove is opened inside the mounting shell, the bidirectional screw rod is rotatably connected to the inside of the mounting shell, and the fixed plate is fixedly connected to the inner wall of the mounting shell.

[0009] Preferably, one end of the bidirectional screw is fixedly connected to a rotating wheel, the outer surface of the bidirectional screw is threadedly connected to a first slider and a second slider, the first slider and the second slider are both slidably connected to the inner wall of the slide groove, the interior of the fixed plate is fixedly connected to a stabilizing rod, and the stabilizing rod is fixedly connected to the inner wall of the mounting shell.

[0010] Preferably, a first synchronization rod is fixedly connected to the first slider, and the end of the first synchronization rod away from the first slider is fixedly connected to the first ear-expanding arc plate; the second slider is fixedly connected to the second synchronization rod, and the end of the second synchronization rod away from the second slider is fixedly connected to the second ear-expanding arc plate.

[0011] Preferably, circular grooves adapted to the stabilizing rod are provided inside the first synchronizing rod and the second synchronizing rod, and the stabilizing rod is slidably connected to the two circular grooves.

[0012] At least one of the above technical solutions adopted in the embodiment of the present utility model can achieve the following beneficial effects:

[0013] First, the ear canal expander provided by the present invention has a compact and lightweight ear hook design, which effectively reduces the volume and weight of the entire expander, making it easy to carry, transport and store, and significantly reducing the manufacturing material cost and space occupancy. At the same time, the anti-slip grooves on the outer surface of the ear hook enhance the friction between the ear hook and the patient's ear, and the counterweight block can effectively balance the weight of the ear canal expander, allowing it to be hung more stably on the patient's ear, effectively preventing the expander from slipping during use, and ensuring stability and safety of use. This design not only solves the problem that existing ear canal expanders are bulky and inconvenient to carry, but also improves the patient's user experience, bringing greater convenience to ear canal examination and treatment.

[0014] Secondly, the utility model realizes rapid and stable expansion of the ear canal through the ear expansion mechanism. Specifically, the rotation of the rotating wheel drives the rotation of the bidirectional screw, which in turn drives the first slider and the second slider to move precisely in the slide groove, and finally drives the first ear expansion arc plate and the second ear expansion arc plate to expand the ear canal through the first synchronization rod and the second synchronization rod. This process is simple and fast to operate, and the expansion force and range are controllable, providing medical staff with a clear field of vision. At the same time, the first arc cushion and the second arc cushion ensure the comfort of the patient. This design not only improves the efficiency and stability of the ear canal expansion, but also fully considers the patient's usage experience. It is a major innovation in the ear canal examination and treatment process. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The technical solutions provided by various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0024] Reference Figures 1 to 4 As shown, an embodiment of the present invention provides an ear canal expander, including a mounting shell 1, to which an ear hook 2 is fixedly connected, an observation port 101 penetrating the mounting shell 1 is provided inside the mounting shell 1, a first ear-expanding arc plate 3 and a second ear-expanding arc plate 4 are relatively arranged in the observation port 101, and an ear-expanding mechanism 5 is provided inside the mounting shell 1 to drive the first ear-expanding arc plate 3 and the second ear-expanding arc plate 4 to move relative to each other.

[0025] like Figures 1 to 4 As shown, this ear canal dilator is designed to be used in pairs, that is, it includes two identical devices, one for the patient's left ear and the other for the right ear. Although the figure only shows the dilator style worn on the right ear, please understand that the corresponding left ear device also has exactly the same structure and function. When using it, the user should choose to wear it on the left ear or right ear according to their own needs, or wear it on both ears at the same time to meet the different needs of ear canal examination or treatment. This binaural design ensures convenient and stable support whether it is for examination or treatment of one or both ear canals.

[0026] The outer surface of the ear hook 2 is provided with anti-slip grooves 6, and the end of the ear hook 2 away from the mounting shell 1 is fixedly connected to a counterweight block 7. The outer surface of the first ear expansion arc plate 3 is pasted with a first arc-shaped cushion 8, and the outer surface of the second ear expansion arc plate 4 is pasted with a second arc-shaped cushion 9.

[0027] The ear expansion mechanism 5 includes a slide 501, a bidirectional screw rod 502, and a fixed plate 508. The slide 501 is opened inside the mounting shell 1, the bidirectional screw rod 502 is rotatably connected to the inside of the mounting shell 1, and the fixed plate 508 is fixedly connected to the inner wall of the mounting shell 1.

[0028] One end of the bidirectional screw rod 502 is fixedly connected to the rotating wheel 503, and the outer surface of the bidirectional screw rod 502 is threadedly connected to the first slider 504 and the second slider 505. The first slider 504 and the second slider 505 are both slidingly connected to the inner wall of the slide groove 501. The inside of the fixed plate 508 is fixedly connected to the stabilizing rod 509, and the stabilizing rod 509 is fixedly connected to the inner wall of the mounting shell 1.

[0029] A first synchronization rod 506 is fixedly connected to the first slider 504, and the end of the first synchronization rod 506 away from the first slider 504 is fixedly connected to the first ear-expanding arc plate 3. A second synchronization rod 507 is fixedly connected to the second slider 505, and the end of the second synchronization rod 507 away from the second slider 505 is fixedly connected to the second ear-expanding arc plate 4.

[0030] Circular grooves adapted to the stabilizing rod 509 are formed inside the first synchronizing rod 506 and the second synchronizing rod 507 , and the stabilizing rod 509 is slidably connected to the two circular grooves.

[0031] Example 1

[0032] like Figures 1 to 4 As shown, the utility model provides an ear canal expander, which includes a mounting shell 1, an ear hook 2, a first ear expansion arc plate 3, a second ear expansion arc plate 4 and an ear expansion mechanism 5.

[0033] The mounting shell 1 is designed to fit comfortably in the hand and features an observation port 101, allowing medical personnel to observe the interior of the ear canal and provide appropriate treatment. The ear hook 2, fixed to the mounting shell 1, is made of a flexible and durable medical-grade silicone material. Its outer surface features anti-slip grooves 6, which effectively prevent the ear canal dilator from slipping during use.

[0034] The first ear-expanding arc plate 3 and the second ear-expanding arc plate 4 are both adhered with arc-shaped cushions 8 and 9 . These cushions are made of soft and harmless materials to ensure the comfort of the patient when expanding the ear canal.

[0035] The ear canal dilator 5 includes a chute 501, a bidirectional screw 502, and a fixed plate 508. The bidirectional screw 502 can be manually rotated by a rotating wheel 503, thereby driving a first slider 504 and a second slider 505 to move toward or away from each other within the chute 501. This design allows the ear canal dilator to easily adapt to the ear canal size of different patients.

[0036] Example 2

[0037] like Figures 1 to 4 As shown, based on the first embodiment, this embodiment further optimizes the stability and comfort of the ear canal expander.

[0038] A counterweight 7 is added to the end of the ear hook 2 away from the mounting shell 1. The counterweight 7 is precisely calculated to effectively balance the weight of the ear canal expander, allowing it to hang more stably on the patient's ear.

[0039] In addition, circular grooves adapted to the stabilizing rod 509 are added to the interior of the first synchronizing rod 506 and the second synchronizing rod 507. The stabilizing rod 509 passes through these circular grooves, ensuring the stability of the slider and the synchronizing rod during movement, further improving the use effect of the ear canal dilator.

[0040] Example 3

[0041] like Figures 1 to 4 As shown, based on the second embodiment, this embodiment improves the material of the ear canal expander to enhance its durability and safety.

[0042] The mounting shell 1 is made of medical-grade polymer material, which has the characteristics of high strength, corrosion resistance, and wear resistance, and can ensure the long-term use of the ear canal expander.

[0043] At the same time, the arc-shaped cushions 8 and 9 of the first ear-expanding arc plate 3 and the second ear-expanding arc plate 4 are also made of softer and more durable materials to provide better comfort and durability.

[0044] In addition, key components in the ear expansion mechanism 5, such as the bidirectional screw rod 502, sliders 504, 505, and synchronization rods 506, 507, are also made of high-strength, wear-resistant materials to ensure the stability and durability of the ear canal expander during use.

[0045] Working Principle: To use this ear canal expander, first attach it to the patient's ear using the ear hook 2, ensuring that the first and second arc-shaped ear expansion plates 3 and 4 are inserted into the patient's ear canal. At the same time, the viewing port 101 of the mounting housing 1 is aligned with the ear canal. To expand the ear canal, the medical professional rotates the wheel 503, which drives the bidirectional screw 502 inside the mounting housing 1.

[0046] Utilizing the characteristics of the bidirectional screw rod 502, its rotation drives the first and second sliders 504, 505, to move toward or away from each other within the chute 501. The first slider 504 is connected to the first ear-enlarging curved plate 3 via a first synchronization rod 506. Therefore, when the first slider 504 moves, it drives the first ear-enlarging curved plate 3 toward the inside or outside of the ear canal. Similarly, the second slider 505 is connected to the second ear-enlarging curved plate 4 via a second synchronization rod 507. Its movement drives the second ear-enlarging curved plate 4 to move accordingly.

[0047] During the expansion process, the design of the first curved cushion 8 and the second curved cushion 9 ensures a more comfortable expansion process, effectively avoiding discomfort to the patient. Furthermore, the stabilizing rod 509 passes through the circular grooves within the first synchronization rod 506 and the second synchronization rod 507, ensuring the stability of the slider and synchronization rods during movement.

[0048] When the ear canal expands to the appropriate size, the medical staff can stop rotating the wheel 503, and the ear canal expander will maintain its current state, thereby providing the medical staff with a clear field of view for inspection and treatment of the ear canal. In addition, the outer surface of the ear hook 2 is provided with anti-slip grooves 6. This design can enhance the friction between the ear hook 2 and the ear, ensuring that the ear canal expander does not slip during use. The counterweight 7 can balance the weight of the ear canal expander, allowing it to hang more stably on the ear. In summary, the ear canal expander provided by the utility model achieves rapid and stable expansion of the ear canal through a simple mechanical structure, which greatly facilitates ear canal inspection and treatment.

[0049] The above description is merely an embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of the claims of the present invention.
