Description

Technical Field

[0001] This utility model relates to the field of nasopharyngoscope auxiliary components, specifically to a nasopharyngoscope that is easy to use. Background Technology

[0002] A fiberoptic nasopharyngoscope is a medical instrument used to examine the nasopharynx, pharynx, and larynx. It can be used for biopsies, surgical treatment of vocal cord nodules or small vocal cord polyps, and removal of foreign bodies from the pharynx. It is a fiber optic device that, during a detailed examination of the larynx, can magnify lesions thousands of times using microscopic imaging technology. Doctors can use the built-in surgical forceps to perform outpatient surgical treatment on vocal cord polyps, vocal cord nodules, and other vocal cord lesions by examining the magnified vocal cord cysts and other lesions. The operation time is short and patients experience virtually no pain.

[0003] However, in current nasopharyngoscope use, the examination channel is usually inserted directly into the patient's nasopharynx. This means that the depth of insertion into the nasopharynx can only be controlled by the operator's experience. This not only makes it difficult to control accurately and effectively, but also makes it easy to accidentally insert too deep and injure the patient's nasopharynx. Utility Model Content

[0004] The purpose of this invention is to provide an easy-to-use nasopharyngoscope to solve the above problems. By having the flexible wing of the depth limiting component contact the periphery of the patient's nostrils, the depth of the examination channel into the patient's nasopharynx can be forcibly limited, as detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This utility model provides an easy-to-use nasopharyngoscope, including a nasopharyngoscope body, wherein the examination channel axis of the nasopharyngoscope body extends forward longitudinally, and a lens for performing image examination is embedded at the front end of the examination channel.

[0007] The periphery of the examination channel is coaxially equipped with a depth limiting component that can slide and change position along the axial direction, which is used to forcibly limit the depth of the examination channel into the patient's nasopharynx.

[0008] The depth limiting component is coaxially integrated at the end away from the lens with a position locking component to prevent the depth limiting component from moving or changing position along the inspection channel axis.

[0009] Preferably, the depth limiting component includes a fitting sleeve and a flexible flap. The fitting sleeve is fitted around the periphery of the examination channel in a coaxial sliding fit, and the flexible flaps that cannot pass smoothly through the patient's nostrils are fixed to both sides of the periphery of the fitting sleeve.

[0010] Preferably, the flexible winglets are all silicone plates with an arc shape.

[0011] Preferably, the position locking component specifically comprises a constraint sleeve coaxially fixed at the end of the mating sleeve away from the lens, which is capable of being stretched outward by force and automatically returning to its original position after being released, and the constraint sleeve after returning to its original position is coaxially tightened around the inspection channel.

[0012] Preferably, the constraint sleeve is a rubber round sleeve.

[0013] Preferably, both outer sides of the constraint sleeve extend outward and are fixedly connected to force-applying protrusions for easy pinching and pulling outward.

[0014] Preferably, the position locking component specifically comprises elastic pressure plates that extend and are fixed to both sides of the end of the sleeve away from the lens, which are capable of being pried open by force and automatically returning to their original position after being released, and the elastic pressure plates after returning to their original position are respectively pressed against the outer sides of the inspection channel.

[0015] Preferably, the elastic pressure plates are all metal springs, and the outer ends of the elastic pressure plates are all inwardly extending rolled edges, and the rolled edges are respectively pressed against the outer sides of the inspection channel.

[0016] Using the aforementioned user-friendly nasopharyngoscope, specifically in the actual use of the nasopharyngoscope body, a depth-limiting component coaxially integrated around the examination channel of the nasopharyngoscope body, capable of sliding and changing position along the axial direction, can forcibly limit the depth of the examination channel into the nasopharynx by having the flexible flaps of the depth-limiting component contact the outer periphery of the patient's nostrils. This achieves accurate control over the depth of insertion into the nasopharynx and also provides a certain safety effect, preventing the examination channel from accidentally inserting too deeply into the nasopharynx. Furthermore, since the depth-limiting component is equipped with a position-locking component to prevent it from moving and changing position along the axial direction of the examination channel, specifically in the first optional position-locking component, the constraint sleeve of the position-locking component on the lid is coaxially tightened around the examination channel to lock the depth-limiting component from moving and changing position along the axial direction of the examination channel. Simultaneously, the lid applying force to open the constraint sleeve releases the lock preventing the depth-limiting component from moving along the axial direction of the examination channel, thus locking the position of the depth-limiting component. The contact locking method is simple and easy to implement, facilitating the stable locking of the depth limiting component in a suitable position for examination depth limitation. It also allows for adaptive adjustment of the depth limiting component's position around the examination channel according to the patient's actual needs, improving the flexibility and applicability of the depth limiting component. Specifically, regarding the second optional position locking component, the elastic pressure plate of the position locking component on the lid is pressed against the outside of the examination channel, preventing the depth limiting component from moving axially along the examination channel. Simultaneously, the lid is forcefully pried open to release the elastic pressure plate from the outside of the examination channel, thus releasing the lock that prevents the depth limiting component from moving axially along the examination channel. The position locking and contact locking methods of the depth limiting component are simple and easy to implement, facilitating the stable locking of the depth limiting component in a suitable position for examination depth limitation. It also allows for adaptive adjustment of the depth limiting component's position around the examination channel according to the patient's actual needs, improving the flexibility and applicability of the depth limiting component.

[0017] The beneficial effects are as follows: 1. This utility model has a depth limiting component that can slide and change position along the axis around the examination channel of the nasopharyngoscope body. Then, by the flexible wing of the depth limiting component contacting the outer periphery of the patient's nostril, the depth of the examination channel into the patient's nasopharynx can be forcibly limited. This not only achieves accurate control of the depth of the nasopharynx, but also plays a certain safety role, avoiding the examination channel from being accidentally inserted too deeply into the nasopharynx.

[0018] 2. The depth limiting component assembly is equipped with a position locking component to prevent the depth limiting component from moving or changing position along the examination channel axis. Subsequently, the constraint sleeve of the bucket lid position locking component is coaxially tightened around the examination channel to lock the depth limiting component from moving or changing position along the examination channel axis. At the same time, the bucket lid applies force to stretch the constraint sleeve to release the lock that prevents the depth limiting component from moving along the examination channel axis. The position locking and contact locking methods of the depth limiting component are simple and easy to implement. This not only makes it easy to stably lock the depth limiting component in a suitable position for examination depth limiting, but also allows for adaptive adjustment of the position of the depth limiting component around the examination channel according to the actual needs of the patient, improving the flexibility and applicability of the depth limiting component.

[0019] 3. The elastic pressure plate of the lid locking component, which is pressed against the outside of the examination channel, can lock the depth limiting component and prevent it from moving along the axial direction of the examination channel. At the same time, the lid can be pried open outward to release the locking of the depth limiting component. The position locking and contact locking methods of the depth limiting component are simple and easy to implement. This makes it easy to stably lock the depth limiting component in a suitable position for examination depth limitation. At the same time, it is easy to adapt the position of the depth limiting component on the periphery of the examination channel according to the actual needs of the patient, thus improving the flexibility and applicability of the depth limiting component.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] See Figures 1-6 As shown, this utility model provides a user-friendly nasopharyngoscope, including a nasopharyngoscope body 1. The examination channel 101 of the nasopharyngoscope body 1 extends longitudinally forward, and a lens 102 for imaging examination is embedded at the front end of the examination channel 101. A depth limiting component 3, which can slide and change position axially, is coaxially assembled around the examination channel 101 to forcibly limit the depth of the examination channel 101 into the patient's nasopharynx. Specifically, the depth limiting component 3 includes a cooperating sleeve 302. The flexible wing 301 and the sleeve 302 are coaxially and slidingly fitted around the periphery of the examination channel 101. Both sides of the sleeve 302 extend outward and are fixed with flexible wing 301 that cannot pass smoothly through the patient's nostrils. The purpose of this setting is to forcibly limit the depth of the examination channel 101 into the patient's nasopharynx by contacting the outer periphery of the patient's nostrils with the flexible wing 301 of the depth limiting component 3. This not only achieves accurate control of the depth of the probe into the nasopharynx, but also plays a certain role in safety.

[0031] See Figures 1-3As shown, the depth limiting component 3 is coaxially coupled with a position locking component 2 at the end away from the lens 102 to prevent the depth limiting component 3 from moving and changing position along the axial direction of the inspection channel 101. Specifically, the first optional method of the position locking component 2 is as follows: The position locking component 2 is coaxially fixed with a constraint sleeve 201 at the end away from the lens 102, which can be stretched outward by force and automatically return to its original position after being released. After the constraint sleeve 201 returns to its original position, it is coaxially tightened around the inspection channel 101. The function of this setting is that the constraint sleeve 201 of the bucket lid position locking component 2 is coaxially tightened around the inspection channel 101 to prevent the depth limiting component 3 from moving and changing position along the axial direction of the inspection channel 101. At the same time, the bucket lid can release the lock that prevents the depth limiting component 3 from moving along the axial direction of the inspection channel 101 by stretching the constraint sleeve 201 outward. The position locking and contact locking method of the depth limiting component 3 is simple and easy to implement.

[0032] See Figures 4-6 As shown, the second optional method of the position locking component 2 is as follows: Specifically, the position locking component 2 is equipped with elastic pressure plates 203 extending and fixedly connected to both sides of the end of the sleeve 302 away from the lens 102. These plates are capable of being pried open with force and automatically returning to their original position after being released. The elastic pressure plates 203, after being released, are respectively pressed against the outer sides of the inspection channel 101. The reason for this arrangement is that the elastic pressure plates 203 of the bucket lid position locking component 2 are elastically pressed against the outside of the inspection channel 101, which can lock the depth limiting component 3 from moving and changing its position along the axial direction of the inspection channel 101. At the same time, the method of prying the bucket lid open with force to remove the elastic pressure plates 203 from the outside of the inspection channel 101 can release the lock that prevents the depth limiting component 3 from moving along the axial direction of the inspection channel 101. The position locking and contact locking methods of the depth limiting component 3 are simple and easy to implement.

[0033] See Figures 1-6As shown, the depth limiting component 3 and the position locking component 2 are respectively modified as follows: the flexible wing 301 is a rounded silicone plate so that it will not hurt the patient when it comes into contact with the outside of the patient's nasal cavity. Specifically, for the position locking component 2, the constraint sleeve 201 is optionally a rubber round sleeve. Both sides of the constraint sleeve 201 extend outward and are fixedly connected to force-applying protrusions 202 for easy pinching and pulling outward. This setting firstly facilitates the constraint sleeve 201 to achieve the effect of applying force and automatically returning to its original position after being released. At the same time, it facilitates the constraint sleeve 201 to be deformed outward smoothly by pinching the force-applying protrusions 202 as the force-applying position. Alternatively, the elastic pressure plates 203 are all metal springs, and the outer ends of the elastic pressure plates 203 are all inwardly extending rolled protrusions 204, and the rolled protrusions 204 are respectively pressed on the outer sides of the inspection channel 101. With this setting, the elastic pressure plates 203 can first achieve the effect of being pried open outward with force and automatically returning to their original position after being released. At the same time, the rolled protrusions 204 can be used to press the outer side of the inspection channel 101 to raise the elastic pressure plates 203 to a certain height, which makes it easier to pry the elastic pressure plates 203 open outward with force later.

[0034] Using the above structure, specifically in the actual use of the nasopharyngoscope body 1, since a depth limiting component 3 capable of sliding and changing position along the axial direction is coaxially combined around the examination channel 101 of the nasopharyngoscope body 1, and the flexible wing 301 of the depth limiting component 3 contacts the outer periphery of the patient's nostril, the depth of the examination channel 101 into the patient's nasopharynx can be forcibly limited. This not only achieves accurate control over the depth of insertion into the nasopharynx, but also provides a certain safety effect, preventing the examination channel 101 from accidentally inserting too deeply into the nasopharynx. Furthermore, due to the combination of the depth limiting component 3... A position locking component 2 is provided to prevent the depth limiting component 3 from moving and changing position along the axial direction of the inspection channel 101. Specifically, for the first optional position locking component 2, the constraint sleeve 201 of the bucket lid position locking component 2 is coaxially tightened around the inspection channel 101 to prevent the depth limiting component 3 from moving and changing position along the axial direction of the inspection channel 101. At the same time, the bucket lid applies force to stretch the constraint sleeve 201 outward to release the lock that prevents the depth limiting component 3 from moving along the axial direction of the inspection channel 101, thus locking and contacting the depth limiting component 3. The locking method is simple and easy to implement, which not only facilitates the stable locking of the depth limiting component 3 in a suitable position for examination depth limitation, but also allows for adaptive adjustment of the position of the depth limiting component 3 on the periphery of the examination channel 101 according to the actual needs of the patient, thus improving the flexibility and applicability of the depth limiting component 3. Specifically, regarding the second optional position locking component 2, the elastic pressure plate 203 of the bucket lid position locking component 2 is elastically pressed against the outside of the examination channel 101, which can lock the depth limiting component 3 from moving and changing position along the axial direction of the examination channel 101. At the same time, the bucket lid is forcefully pried outward to open the elastic pressure plate 203 and remove it from the outside of the examination channel 101, thus releasing the lock that prevents the depth limiting component 3 from moving along the axial direction of the examination channel 101. The position locking and contact locking methods of the depth limiting component 3 are simple and easy to implement, which not only facilitates the stable locking of the depth limiting component 3 in a suitable position for examination depth limitation, but also allows for adaptive adjustment of the position of the depth limiting component 3 on the periphery of the examination channel 101 according to the actual needs of the patient, thus improving the flexibility and applicability of the depth limiting component 3.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
