[0001] The utility model relates to the technical field of medical instruments, in particular to an ear hole searchlight for otology. Background Art

[0002] Otolaryngology is a department that examines and treats diseases inside the ear. It mainly focuses on diseases related to the internal structure of the ear, which usually require medication. For example, there are diseases such as external auditory canal eczema, external auditory canal injury, and tympanitis. When medical staff examine patients, they need to observe the inside of the ear hole and use a searchlight to illuminate the inside of the ear hole to avoid darkness inside the ear hole that makes it difficult to observe.

[0003] In actual use, existing ear hole searchlights in otolaryngology usually adopt head-mounted searchlights or handheld flashlights. When the light of the searchlight is emitted into the ear hole, the brightness inside the ear hole is increased, and then the medical staff uses a handheld magnifying glass to observe the inside of the ear hole, which effectively solves the problem that the light inside the ear hole is dark and cannot be observed.

[0004] However, during the actual inspection process, since the light source of the searchlight is outside the ear hole, medical staff are easily affected by external light when observing with a magnifying glass, making it difficult to clearly show the internal conditions of the ear hole, which significantly reduces the inspection effect. Therefore, the present application proposes an ear hole searchlight for otolaryngology that can prevent the influence of external light and improve the inspection effect. Utility Model Content

[0027] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0028] Example

[0029] like Figure 1-Figure 4 As shown, the present invention proposes an ear hole searchlight for ear internal medicine, comprising a handheld tube 1, an endoscope lamp head 2 is fixedly mounted on one end of the handheld tube 1, an objective lens 24 is fixedly mounted on the inner wall of the endoscope lamp head 2, and the light reflected from the inside of the ear hole can be received through the objective lens 24 for further magnification and observation by the eyepiece 53, a plurality of LED bulbs 3 are fixedly mounted on the inner wall of the endoscope lamp head 2 and on one side of the objective lens 24, and the light projected by the LED bulbs 3 can illuminate the inside of the ear hole, solving the problem that the light inside the ear hole is dark and inconvenient to observe; the handheld tube 1 is movably mounted on one end away from the endoscope lamp head 2 The telescopic tube 5 has an eyepiece 53 fixedly installed inside it. The image of the objective lens 24 can be further magnified through the eyepiece 53. The telescopic tube 5 can be stretched and adjusted to facilitate the adjustment of the focal length, ensuring that the medical staff can observe the internal structure of the ear hole more clearly in detail, thereby improving the observation effect; the end of the telescopic tube 5 away from the handheld tube 1 is fixedly installed with an observation tube 6, which is made of rubber. When the medical staff puts their eyes on the observation tube 6, it avoids discomfort to the eyes. At this time, the medical staff's line of sight is inside the searchlight, which can prevent external light from affecting the observation, thereby effectively improving the inspection effect.

[0030] Furthermore, an annular connecting plate 61 is fixedly installed at one end of the observation tube 6 close to the telescopic tube 5, and a plurality of positioning posts 62 are fixedly installed at one end of the annular connecting plate 61. When the annular connecting plate 61 is docked and installed on the telescopic tube 5, the above-mentioned positioning posts 62 are embedded in the docking grooves excavated at the end of the telescopic tube 5 and tightly engaged with it, making it convenient to disassemble and assemble the observation tube 6. Since the observation tube 6 is in contact with the eyes of medical staff, it needs to be cleaned and disinfected frequently. Therefore, it is easy to disassemble and assemble, and can provide convenience for its cleaning and disinfection.

[0031] Secondly, a battery box 21 is fixedly installed on the outer wall of the endoscope lamp head 2, and at least two batteries are embedded in the battery box 21. The LED bulb 3 is electrically connected to the circuit board inside the battery box 21 through a wire, and the control switch on the battery box 21 is controlled to conveniently turn on or off the LED bulb 3; the part of the above-mentioned wire located inside the endoscope lamp head 2 is fixedly bonded to the inner wall of the endoscope lamp head 2 by glue to prevent the wire from blocking the side of the objective lens 24, thereby ensuring the observation effect; the open end of the above-mentioned battery box 21 is snap-fitted with a cover plate 23, and a sealing gasket 22 is placed between the cover plate 23 and the battery. When the cover plate 23 is fixedly installed on the open end of the battery box 21, the sealing gasket 22 can form a sealing structure on the outside of the battery. When the outer surface of the endoscope lamp head 2 is flushed, the probability of water entering the battery box 21 can be reduced, thereby improving its waterproof effect.

[0032] Furthermore, a plurality of embedded grooves 51 are carved on the annular plate provided at one end of the telescopic tube 5, and a plurality of magnetic strips 11 are fixedly installed on the end of the hand-held tube 1 close to the annular plate. When the telescopic tube 5 is received inside the hand-held tube 1, the above-mentioned magnetic strips 11 are embedded in the embedded grooves 51 and are magnetically attracted to the iron sheet installed inside, ensuring that the telescopic tube 5 can be stably received inside the hand-held tube 1; a plurality of ring-shaped distributed handles 4 are fixedly installed on the outer wall of the hand-held tube 1, and medical staff can stabilize the hand-held searchlight by inserting their fingers into the handles 4, which is convenient for detection operations. When the searchlight is placed on the table, two of the handles 4 are in contact with the table surface, thereby acting as a support frame, ensuring that the searchlight can be stably placed on the table surface.

[0033] Secondly, a long strip limiting groove 12 is carved on the inner wall of the hand-held tube 1, and a long strip limiting plate 54 is fixedly installed on the outer wall of the telescopic tube 5. The long strip limiting plate 54 is inserted into the long strip limiting groove 12 and slidably connected thereto. During the stretching and adjustment of the telescopic tube 5, the long strip limiting groove 12 is used to limit the long strip limiting plate 54, which can prevent the telescopic tube 5 from rotating, ensuring that the magnetic strip 11 and the embedded groove 51 can always remain aligned. When the telescopic tube 5 needs to be stored inside the hand-held tube 1, there is no need to adjust the position of the magnetic strip 11 and the embedded groove 51, which is convenient for operation.

[0034] It is worth noting that a first annular limit plate 13 is fixedly installed inside the telescopic tube 5 and on one side close to the endoscope lamp head 2. The telescopic tube 5 is arranged on one side of the first annular limit plate 13. When the telescopic tube 5 is stored in the handheld tube 1, the moving range of the telescopic tube 5 is limited by the first annular limit plate 13 to ensure that the end of the telescopic tube 5 contacts the first annular limit plate 13, thereby improving the stability of the telescopic tube 5 after storage; a second annular limit plate 52 is fixedly installed on the inner wall of the above-mentioned telescopic tube 5, and the second annular limit plate 52 is installed on the side close to the observation tube 6. When the eyepiece 53 is installed in the telescopic tube 5, the second annular limit plate 52 contacts the edge of the eyepiece 53, and the eyepiece 53 is limited by the second annular limit plate 52, thereby improving the stability of the eyepiece 53 after installation.

[0035] In this embodiment, the medical staff first inserts one hand into the handle 4 to stabilize the handheld searchlight, then attaches the end of the endoscope lamp head 2 to the outer periphery of the patient's ear hole, turns on the control switch installed on the battery box 21, and causes the LED bulb 3 to project light into the patient's ear hole. When the projected light contacts the internal structure of the ear hole, it will be reflected to the objective lens 24. The objective lens 24 can further magnify the image on the eyepiece 53. During this process, the medical staff attaches their eyes to the observation tube 6, and through the cooperation of the eyepiece 53 and the objective lens 24, they can clearly observe the ear. The condition of the internal structure of the hole; pulling the telescopic cylinder 5 can adjust the distance between the objective lens 24 and the eyepiece 53, which is convenient for adjusting the focal length, further improving the details of the internal structure of the ear hole, and enhancing the clarity of observation; when the searchlight in the present application is in use, there is no need for medical staff to hold a magnifying glass for observation. The searchlight has the function of providing light source and magnifying the internal structure of the ear hole, combining the two functions into one, which is convenient to use. Moreover, when the medical staff examines the inside of the ear hole, their line of sight is inside the searchlight, which can prevent external light from affecting the clarity of observation, thereby effectively improving the inspection effect.

[0036] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
