Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an earwax removal device for otolaryngology. Background Technology

[0002] Earwax is a pale yellow, viscous secretion produced by the ceruminous glands in the external auditory canal. It dries in the air and forms thin flakes. Most earwax is expelled naturally during chewing, talking, and even sneezing. However, in some individuals, due to active ceruminous gland secretion or prolonged exposure to polluted air without proper protective gear, earwax tends to clump together and block the external auditory canal, leading to hearing loss, ear pain, and reflexive coughing. Excessive earwax also easily breeds bacteria, increasing the risk of external auditory canal infection. In such cases, for the sake of ear canal health, it is necessary to go to the hospital for professional removal of the accumulated earwax. Current methods involve using a series of medical instruments to remove the earwax: first, a 5% sodium hydroxide solution is dripped into the ear canal using a dropper or syringe to soften the earwax; then, an ear pick is used to scoop the earwax away from the ear wall; next, tweezers are used to remove the earwax; finally, a cotton swab dipped in medical alcohol is used to clean and disinfect the external auditory canal. The entire earwax removal process involves a large number of medical instruments, requiring doctors to constantly change instruments. Furthermore, each instrument must be cleaned and disinfected before and after use, making the entire earwax removal process cumbersome and time-consuming. The subsequent cleaning, disinfection, and storage of the instruments are also a significant workload. Utility Model Content

[0003] The purpose of this invention is to provide an earwax removal device for otolaryngology based on practical needs. This device can independently complete the operations of dripping medication into the ear canal, lifting earwax, and clamping and removing earwax. While simplifying the number of medical instruments and reducing the hospital's medical instrument procurement costs, it also effectively reduces the workload of medical staff in cleaning, disinfecting, and storing medical instruments.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An earwax removal device for otolaryngology includes a handle and an earwax removal part. The top of the handle is equipped with a press-pull cord mechanism, which includes a press spring, a slider, a first spring, a press ball, and a pull cord. A first groove is carved into the middle of the top of the handle. The left inner wall of the first groove is fixedly connected to one end of the first spring, and the other end of the first spring is fixedly connected to one end of the slider. The other end of the slider is fixedly connected to the pull cord. A second groove is carved into the center of the top surface of the slider. The inner wall of the second groove is spherical. One end of the press spring is hinged to the right top edge of the first groove, and the other end is a free end. A pressing ball is fixedly installed at the center of the bottom surface of the ear canal. One end of the pull rope is fixedly connected to the slider, and the other end of the pull rope passes through the slide inside the front end of the handle body and splits into two strands, which are fixedly connected to the earwax removal mechanism inside the earwax removal section. The bottom end of the pressing ball contacts the left edge of the second groove when the first spring is naturally extended. After the pressing ball is pressed down by the pressing spring, it enters the second groove, thereby pushing the slider to slide towards the left wall of the first groove, which in turn drives the pull rope to move into the first groove. The earwax removal mechanism clamps the earwax under the action of the pull rope. At this time, the clamped earwax can be removed from the external auditory canal by moving the handle. After the pressing ball is fully pressed down, its bottom end contacts the bottom end of the second groove.

[0005] Specifically, the earwax removal part includes a retaining ring and an earwax clamping mechanism. The retaining ring has a "U" shaped structure, and its bottom end is fixedly connected to the top end of the handle. Two mounting plates are fixedly fixed one above the other on the inner side of the middle of the retaining ring, and a rotating shaft is fixed vertically between the mounting plates. The earwax clamping mechanism is installed inside the retaining ring and includes a pull rod, a clamping plate, and a second spring. The front end of the pull rod has an "S" shaped structure, and a through round hole is opened in the middle and rear part of the pull rod. The two pull rods are symmetrically hinged to the rotating shaft through the round hole in the middle and rear part. The pull rope passes through the slide and splits into two strands, which are fixedly connected to the bottom ends of the two pull rods respectively. The clamping plate is fixedly installed at the two innermost positions of the "S" shaped structure at the front end of the pull rod. One end of the second spring is fixedly connected to the outer side of the rear end of the pull rod, and the other end is fixedly connected to the inner wall of the retaining ring. The installation direction of the second spring is perpendicular to the outer side of the pull rod.

[0006] In the above technical solution, as the pressing ball is pressed down, the slider drives the pull rope to move, and the pull rope pulls the lever to close the clamp at the front end of the lever, thereby clamping the earwax located between the clamps and lifted by the front end of the retaining ring, thus clamping and removing the earwax.

[0007] Furthermore, the bottom of the handle is also provided with a liquid injection mechanism, which includes an injection rod, an injection chamber, a liquid cavity, and a liquid flow channel. The handle body has a cavity inside, and the injection rod is inserted from the left end of the cavity. The injection plug at the front end of the injection rod divides the cavity into a left injection chamber and a right liquid cavity. The front end of the liquid cavity converges to form a liquid flow channel. A medicine outlet is opened on each side of the front end of the retaining ring, and the liquid flow channel connects the liquid cavity and the medicine outlet.

[0008] In the above technical solution, by pulling out and pushing in the injection rod, a 5% sodium hydroxide solution or even a drug solution can be drawn into the device or dripped into the earwax, thereby softening the earwax or treating the ear canal after the earwax is removed (mainly to eliminate inflammation). After the earwax is softened, the earwax is lifted by the flat front end of the retaining ring, making it easier to clamp and remove the earwax.

[0009] Specifically, an acupressure plate is fixed to the bottom of the injection rod, and a scale rod is fixedly connected to the acupressure plate above the injection rod. One end of the scale rod is fixedly connected to the acupressure plate, and the other end is inserted into the air cavity opened at the bottom of the top of the handle. An air hole is opened at the end of the air cavity, and the air hole extends through to the top of the handle and communicates with the outside. The scale rod is marked with graduations.

[0010] It should be noted that the scale markings on the graduated rod correspond to the volume of the inhaled medication. The specific scale value is obtained by calibrating the volume of the inhaled medication in the medication chamber and medication flow channel per unit length when the graduated rod is pulled out.

[0011] Furthermore, to prevent the pressing spring from lifting up and affecting the storage of the device, the earwax removal device is also equipped with a storage sleeve. When the device is not in use and is stored away, the storage sleeve is placed on the middle of the handle where the pressing spring is located after the pressing spring is pressed down to be flush with the top surface of the handle, thereby preventing the pressing spring from being lifted up.

[0012] Furthermore, to prevent the earwax removal part from injuring the ear wall when probing into the ear canal and picking up earwax, the front end of the retaining ring is flat and smooth, and the outer ring of the retaining ring and the connection between the front end of the handle and the retaining ring are all rounded.

[0013] Preferably, the width of the slider is equal to the width of the first groove, and the width of the clamping plate is less than the width of the retaining ring.

[0014] Preferably, the outer surface of the handle is machined with anti-slip texture.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This utility model of an external auditory canal earwax removal device can independently complete the operations of instilling medication into the ear canal, lifting earwax, and clamping and removing earwax. While simplifying the number of medical instruments and reducing the hospital's medical instrument procurement costs, it also effectively reduces the workload of medical staff in cleaning, disinfecting, and storing medical instruments.

Detailed Implementation

[0022] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete. Example

[0023] like Figure 1As shown, this utility model provides an earwax removal device for otolaryngology, including a handle part 1 and an earwax removal part 2. The top of the handle part 1 is provided with a pressing and pulling rope mechanism, which includes a pressing spring 3, a slider 4, a first spring 5, a pressing ball 6, and a pull rope 7. A first groove 8 is carved in the middle of the top of the handle part 1. The left inner wall of the first groove 8 is fixedly connected to one end of the first spring 5, and the other end of the first spring 5 is fixedly connected to one end of the slider 4. The other end of the slider 4 is fixedly connected to the pull rope 7. Figure 2 As shown, a second groove 9 is carved in the center of the top surface of the slider 4. The inner wall of the second groove 9 is spherical. One end of the pressing spring 3 is hinged to the top right edge of the first groove 8, and the other end is a free end. A pressing ball 6 is fixedly installed in the center of the bottom surface of the pressing spring 3. One end of the pull rope 7 is fixedly connected to the slider 4. The other end of the pull rope 7 passes through the slide 10 inside the front end of the handle part 1 and splits into two strands, which are fixedly connected to the earwax clamping mechanism in the earwax removal part 2. The bottom end of the pressing ball 6 contacts the left edge of the second groove 9 when the first spring 5 is naturally extended. After the pressing ball 6 is pressed down by the pressing spring 3, it enters the second groove 9, thereby pushing the slider 4 to slide towards the left wall of the first groove 8, thereby driving the pull rope 7 to move into the first groove 8, so that the earwax clamping mechanism clamps the earwax under the action of the pull rope. At this time, the clamped earwax can be removed from the external auditory canal by moving the handle part 1. After the pressing ball 6 is fully pressed down, its bottom end contacts the bottom end of the second groove 9.

[0024] like Figure 3 As shown, the earwax removal part 2 includes a retaining ring 11 and an earwax clamping mechanism. The retaining ring 11 has a "U" shaped structure, and its bottom end is fixedly connected to the top end of the handle part 1. Two mounting plates 12 are fixedly fixed to the inner side of the middle part of the retaining ring 11, one above the other. A rotating shaft 13 is vertically fixed between the mounting plates 12. The earwax clamping mechanism is installed inside the retaining ring 11 and includes a pull rod 14, a clamping plate 15, and a second spring 16. The front end of the pull rod 14 has an "S" shaped structure, and the middle and rear part of the pull rod 14 is open. A through-hole is provided, and two pull rods 14 are hinged to the rotating shaft 13 in a symmetrical structure, one above the other, through the hole at the rear. The pull rope 7 passes through the slide rail 10 and splits into two strands, which are respectively fixedly connected to the bottom ends of the two pull rods 14. The clamping plate 15 is fixedly installed at the two innermost positions of the "S"-shaped structure at the front end of the pull rod 14. One end of the second spring 16 is fixedly connected to the outer side of the rear end of the pull rod 14, and the other end is fixedly connected to the inner wall of the retaining ring 11. The installation direction of the second spring 16 is perpendicular to the outer side of the pull rod 14.

[0025] Furthermore, in this embodiment, the bottom of the handle part 1 is also provided with a liquid injection mechanism. The liquid injection mechanism includes an injection rod 17, an injection cavity 18, a liquid cavity 19, and a liquid flow channel 20. The handle part 1 has a cavity inside its lower part. The injection rod 17 is inserted from the left end of the cavity. The injection plug 21 at the front end of the injection rod 17 divides the cavity into the injection cavity 18 on the left and the liquid cavity 19 on the right. The front end of the liquid cavity 19 is constricted to form the liquid flow channel 20. A medicine outlet 28 is opened on each side of the front end of the retaining ring 11. The liquid flow channel 20 connects the liquid cavity 19 and the medicine outlet 28.

[0026] In this embodiment, by pulling out and pushing in the injection rod 17, a 5% sodium hydroxide solution or even a drug solution can be drawn into the device or dripped into the earwax, thereby softening the earwax or treating the ear canal after earwax removal, mainly to eliminate inflammation. After the earwax is softened, the earwax is lifted by the flat front end of the retaining ring 11, making it easier to clamp and remove the earwax.

[0027] Specifically, an acupressure plate 22 is fixed to the bottom of the injection rod 17, and a scale rod 23 is fixedly connected to the acupressure plate 22 above the injection rod 17. One end of the scale rod 23 is fixedly connected to the acupressure plate 22, and the other end is inserted into the air chamber 24 opened at the bottom of the top of the handle part 1. An air hole 25 is opened at the end of the air chamber 24, and the air hole 25 extends through to the top of the handle part 1 and communicates with the outside. The scale rod 23 is marked with graduations.

[0028] In this embodiment, the scale markings on the scale rod 23 correspond to the volume of the inhaled liquid. The specific scale value is obtained by calibrating the volume of the inhaled liquid in the liquid cavity 19 and the liquid flow channel 20 by pulling out the scale rod 23 by a unit length. The calibration method is existing technology and will not be described in detail here.

[0029] like Figure 4 As shown, the ENT earwax removal device provided in this embodiment also includes a storage sleeve 26. When the device is not in use and is stored, the storage sleeve 26 is placed on the middle part of the handle 1 at the location of the pressing spring 3 after the pressing spring 3 is pressed down to be flush with the top surface of the handle 1.

[0030] In this embodiment, to prevent the earwax removal part from injuring the ear wall when probing into the ear canal and picking up earwax, the front end of the retaining ring 11 is flat and smooth, and the outer ring of the retaining ring 11 and the connection between the front end of the handle part 1 and the retaining ring 11 are all rounded.

[0031] The width of the slider 4 is equal to the width of the first groove 8, and the width of the clamping plate 15 is less than the width of the retaining ring 11.

[0032] The outer surface of the handle part 1 is machined with anti-slip texture 27.

[0033] Working principle & process: Medical staff pull out the injection rod 17 and, according to the scale markings on the subsequently pulled-out scale rod 23, draw a certain amount of 5% sodium hydroxide solution or medication into the medication chamber 19. Then, they remove the storage sleeve 26, and press the spring 3, which is lifted by the first spring 5 and the slider 4. Under sufficient lighting, the earwax removal part is inserted into the earwax location in the external auditory canal. The injection rod 17 is pushed, causing a certain amount of 5% sodium hydroxide solution to flow out of the medication chamber 19. The earwax removal part is then withdrawn, and after a period of time for the earwax to soften, it is reinserted into the earwax location. The earwax is then lifted using the flat front end of the retaining ring 11. After lifting, the earwax removal part is slightly pushed outwards. Slightly pull out a small distance so that the picked-up earwax is positioned between the two clamping plates 15. Finally, press down on the pressing spring 3 so that the pressing ball 6 enters the second groove 9, thereby pushing the slider 4 to slide towards the left wall of the first groove 8. The slider 4 drives the pull rope 7 to move, and the pull rope 7 pulls the pull rod 14 to clamp the clamping plate 15 at the front end of the pull rod, thereby clamping the picked-up earwax. At the same time as the earwax removal part is pulled out, the earwax is also clamped and removed. After the earwax is removed, release the pressed pressing spring 3. The pressing spring 3 is pushed up again under the action of the first spring 5 and the slider 4. The pull rod 14 is also reset under the action of the second spring 16, and the clamping plate 15 returns to the open state, making it convenient to remove the earwax for centralized treatment.

[0034] After the device is used, the injection rod 17 is completely pulled out. The injection rod 17, the entire device and the inside of the cavity are rinsed and disinfected. After drying in an oven, the injection rod 17 is pushed back into the cavity and put on a storage cover for storage, ready for the next use. Example

[0035] In this example, based on Embodiment 1, as follows: Figure 5 As shown, the front end of the earwax removal part can be bent into a knee shape, so that the earwax removal part can penetrate and remove earwax deeper into the external auditory canal. The specific working principle and earwax removal operation process remain unchanged.

[0036] It should be understood that the above description of the preferred embodiments is quite detailed, but it should not be considered as a limitation on the scope of protection of this utility model. Those skilled in the art can make substitutions or modifications under the guidance of this utility model without departing from the scope of protection of the claims of this utility model, and all such substitutions or modifications shall fall within the scope of protection of this utility model. The scope of protection of this utility model shall be determined by the appended claims.
