Description

Technical Field

[0001] The present disclosure relates to the field of medical devices, and specifically, to an adenoid stent and an adenoid support assembly. Background Art

[0002] The adenoid, also known as the pharyngeal tonsil or nasopharyngeal tonsil, is located at the top of the nasopharynx and the posterior pharyngeal wall, belongs to lymphoid tissue, and has an orange-petal-like surface. Like the tonsils, the adenoid gradually grows with age after birth, is in a period of vigorous proliferation at the age of 2 - 6 years, and gradually shrinks after the age of 10. Adenoid hypertrophy especially occurs frequently in infants and young children. The nasopharyngeal cavity of children is narrow, and the hypertrophic adenoid will cause the posterior nasal airway of the child to become narrow. Therefore, adenoid hypertrophy is often complicated with rhinitis and sinusitis, and there are symptoms such as nasal congestion and runny nose.

[0003] However, the existing adenoid stents cannot take into account the ventilation of the nasal airway. After using the adenoid stent, the problem of nasal airway stenosis cannot be solved in a short time. Summary of the Invention

[0004] The purpose of the present disclosure is to provide an adenoid stent and an adenoid support assembly to solve the technical problem that it is impossible to take into account both the support of the adenoid and the ventilation of the nasal airway.

[0005] To achieve the above purpose, the present disclosure provides an adenoid stent, including: a tubular support part for supporting in the nasal passage; a first expansion support part for supporting at the anterior nostril, the first expansion support part is arranged at the first end of the tubular support part and expands radially outward compared with the tubular support part; and a second expansion support part for pressing the adenoid against the posterior pharyngeal wall of the nasopharynx, the second expansion support part is arranged at the second end of the tubular support part opposite to the first end and expands radially outward compared with the tubular support part; wherein, the first expansion support part, the second expansion support part and the tubular support part are coaxially arranged, and the first expansion support part, the second expansion support part and the tubular support part are configured as a mesh structure capable of telescoping along the radial direction.

[0006] Optionally, the second expansion support part expands outward in a spherical shape.

[0007] Optionally, in the no-load state, the length of the second expansion support part is 10 mm - 40 mm, and the length of the tubular support part is 10 mm - 100 mm.

[0008] Optionally, in the no-load state, the outer diameter of the second expansion support part is 12 mm - 28 mm, and the outer diameter of the tubular support part is 5 mm - 15 mm.

[0009] Optionally, the first expansion support portion includes: a first expansion structure for supporting the nasal septum mucosa, the first expansion structure being connected to the tubular support portion and expanding spherically outward in the radial direction compared to the tubular support portion; and a second expansion structure for supporting in the nasal vestibule, the second expansion structure being connected to a side of the first expansion structure away from the tubular support portion and expanding spherically outward in the radial direction compared to the tubular support portion.

[0010] Optionally, in the no-load state, the outer diameter of the first expansion structure is greater than the outer diameter of the second expansion structure.

[0011] Optionally, in the no-load state, the length of the second expansion structure is 8 mm - 15 mm, the length of the first expansion structure is 10 mm - 40 mm, the outer diameter of the second expansion structure is 8 mm - 15 mm, and the outer diameter of the first expansion structure is 12 mm - 28 mm.

[0012] Optionally, it further includes a fixing member disposed on a side of the first expansion support portion away from the tubular support portion. When the adenoid stent is placed in the nasal cavity, the fixing member can extend out of the nostril to fix the adenoid stent.

[0013] Optionally, the first expansion support portion, the second expansion support portion, and the tubular support portion are integrally woven and formed with silk thread.

[0014] Based on the above technical solution, the present disclosure further provides an adenoid support assembly, including the adenoid stent in the above technical solution and a connecting member for connecting two of the adenoid stents to each other outside the nostril.

[0015] Through the above technical solutions, the adenoid stent provided by the present disclosure includes a second expansion support portion, a tubular support portion, and a first expansion support portion that are sequentially connected and coaxially arranged. Since the second expansion support portion, the tubular support portion, and the first expansion support portion are all configured as a mesh structure that can expand and contract radially, when it is necessary to place the adenoid stent into the nasal cavity of a patient, the first expansion support portion, the tubular support portion, and the second expansion support portion can be compressed radially first, and then the second expansion support portion, the tubular support portion, and the first expansion support portion are sequentially inserted into the nasal cavity along the axial direction. When the second expansion support portion passes through the nasal vestibule, the nasal limen, the nasal septum mucosa, the nasal passage, and finally reaches the adenoid, the compression on the second expansion support portion, the tubular support portion, and the first expansion support portion is removed, so that the second expansion support portion, the tubular support portion, and the first expansion support portion can expand radially and support in the nasal cavity of the patient. Among them, the second expansion support portion can expand and press the adenoid against the posterior wall of the nasopharynx to improve the airway obstruction caused by adenoid hypertrophy. The tubular support portion can expand into a tubular structure to adapt to the structure of the nasal passage and provide uniform supporting force for the nasal passage. The first expansion support portion can expand to adapt to the structure of the anterior nasal aperture and support the anterior nasal aperture, thereby improving the stenosis of the nasal airway. Therefore, the adenoid stent in the present disclosure can support both the nasal airway and the adenoid, relieve the nasal congestion caused while treating adenoid hypertrophy, and improve the ventilation condition of the patient. In addition, the second expansion support portion, the tubular support portion, and the first expansion support portion can elastically deform radially, so that the adenoid stent can be applicable to different internal sizes of the nasal cavity, thereby improving the applicability and comfort of the adenoid stent. The adenoid support assembly provided by the present disclosure has the same technical effects as the adenoid stent in the above technical solutions. To avoid unnecessary repetition, it will not be elaborated here.

[0016] Other features and advantages of the present disclosure will be described in detail in the following specific implementation section. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will describe the detailed implementation manners of the present disclosure in conjunction with the accompanying drawings. It should be understood that the detailed implementation manners described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.

[0023] In the present disclosure, unless otherwise stated, the orientation terms such as "inside, outside" refer to the inside and outside relative to the contour of the corresponding component itself. The term such as "no-load state" refers to the state of the adenoid stent when it is not compressed and completely relaxed. "First", "second", etc. are used to distinguish one element from another, and do not have sequence and importance. In addition, when the following description involves the accompanying drawings, the same reference numerals in different drawings represent the same elements.

[0024] According to the detailed implementation manners of the present disclosure, an adenoid stent is provided. Referring to Figure 1 as shown, the adenoid stent may include a second expansion support part 3, a tubular support part 1, and a first expansion support part 2. The tubular support part 1 is used to support in the nasal cavity, the first expansion support part 2 is used to support at the anterior nasal aperture, the first expansion support part 2 is arranged at the first end of the tubular support part 1 and expands radially outward compared with the tubular support part 1. The second expansion support part 3 is used to press the adenoid against the posterior wall of the nasopharynx. The second expansion support part 3 is arranged at the second end of the tubular support part 1 opposite to the first end and expands radially outward compared with the tubular support part 1. Among them, the second expansion support part 3, the tubular support part 1, and the first expansion support part 2 may be coaxially arranged in sequence, and the first expansion support part 2, the second expansion support part 3, and the tubular support part 1 are all configured as a mesh structure capable of telescoping along the said radial direction.

[0025] Through the above technical solution, the adenoid stent provided by the present disclosure includes a second expansion support portion 3, a tubular support portion 1, and a first expansion support portion 2 that are sequentially connected and coaxially arranged. Since the second expansion support portion 3, the tubular support portion 1, and the first expansion support portion 2 are all constructed as a radially telescopic mesh structure, when the adenoid stent needs to be placed into the nasal cavity of a patient, the first expansion support portion 2, the tubular support portion 1, and the second expansion support portion 3 can be compressed radially first, and then the second expansion support portion 3, the tubular support portion 1, and the first expansion support portion 2 are axially inserted into the nasal cavity in sequence. When the second expansion support portion 3 passes through the nasal vestibule, nasal limen, nasal septum mucosa, nasal passage and finally reaches the adenoid, the compression on the second expansion support portion 3, the tubular support portion 1, and the first expansion support portion 2 is removed, so that the second expansion support portion 3, the tubular support portion 1, and the first expansion support portion 2 can radially expand and support in the nasal cavity of the patient. Among them, the second expansion support portion 3 can expand to press the adenoid against the posterior wall of the nasopharynx to improve airway obstruction caused by adenoid hypertrophy. The tubular support portion 1 can expand into a tubular structure to adapt to the structure of the nasal passage and provide uniform support force for the nasal passage. The first expansion support portion 2 can expand to adapt to the structure of the anterior nostril and support the anterior nostril, thereby improving nasal airway stenosis. Therefore, the adenoid stent in the present disclosure can support both the nasal airway and the adenoid, relieve the induced nasal congestion while treating adenoid hypertrophy, and improve the ventilation condition of the patient. In addition, the second expansion support portion 3, the tubular support portion 1, and the first expansion support portion 2 can elastically deform radially, so that the adenoid stent can be applicable to different internal nasal cavity sizes, thereby improving the applicability and comfort of the adenoid stent.

[0026] In addition, in the specific embodiment of the present disclosure, the second expansion support portion 3, the tubular support portion 1, and the first expansion support portion 2 may also be arranged non-coaxially. For example, in the no-load state, the second expansion support portion 3 can expand radially outward on one side of the central axis of the adenoid stent, which can not only ensure that the second expansion support portion 3 can press the adenoid against the posterior wall of the nasopharynx, but also avoid the extended second expansion support portion 3 blocking food from entering the esophagus.

[0027] Reference Figure 1As shown, the second expansion support portion 3 can have any suitable shape. To ensure comfort in use, the second expansion support portion 3 can expand outward in a spherical shape, so that the second expansion support portion 3 has a smooth outer contour and prevents the second expansion support portion 3 from scratching the mucosa of the patient. It should be noted here that the spherical expansion in this disclosure means approximately spherical expansion. That is, in the no-load state, the shape of the second expansion support portion 3 and the following first expansion structure 21 and second expansion structure 22 can be slightly different from the ideal spherical shape. For example, it can be an ellipsoidal shape. In addition, the outer diameter of the second expansion support portion 3 and the following first expansion structure 21 and second expansion structure 22 described in this disclosure refers to the maximum outer diameter along the radial direction of the adenoid stent.

[0028] In a specific embodiment of this disclosure, in the no-load state, the length of the second expansion support portion 3 can be 10 mm - 40 mm, the length of the tubular support portion 1 can be 10 mm - 100 mm, the outer diameter of the second expansion support portion 3 can be 12 mm - 28 mm, and the outer diameter of the tubular support portion 1 can be 5 mm - 15 mm. Specifically, the length of the second expansion support portion 3 can be 12 mm - 20 mm, preferably 15 mm, the length of the tubular support portion 1 can be 32 mm - 38 mm, preferably 35 mm, the outer diameter of the second expansion support portion 3 can be preferably 15 mm - 25 mm, and the outer diameter of the tubular support portion 1 can be preferably 10 mm - 13 mm, so that the size of the adenoid stent can adapt to the internal structure of the airways of most patients.

[0029] In a specific embodiment of this disclosure, the first expansion support portion 2 can be configured in any suitable manner. As an option, the first expansion support portion 2 can expand outward in a spherical shape. As another option, the first expansion support portion 2 can include a first expansion structure 21 and a second expansion structure 22. Among them, the first expansion structure 21 is used to support the nasal septum mucosa. The first expansion structure 21 is connected to the first end of the tubular support portion 1 and expands outward in a spherical shape along the radial direction compared with the tubular support portion 1. The second expansion structure 22 is used to support in the nasal vestibule. The second expansion structure 22 is connected to the side of the first expansion structure 21 away from the tubular support portion 1 and expands outward in a spherical shape along the radial direction compared with the tubular support portion 1. When the compression on the adenoid stent is withdrawn, the first expansion structure 21 can stretch approximately spherically, thereby providing a uniform compressive force on the nasal septum mucosa. The second expansion structure 22 can stretch approximately spherically, thereby providing a uniform supporting force on the nasal vestibule. The groove formed at the connection of the first expansion structure 21 and the second expansion structure 22 can avoid the nasal limen of the patient, thereby improving the comfort in use of the adenoid stent. The outer diameters of the first expansion structure 21 and the second expansion structure 22 are larger than the outer diameter of the tubular support portion 1, which can increase the supporting force on the nasal septum and nasal vestibule.

[0030] In a specific embodiment of the present disclosure, reference is made to Figure 1 As shown, in the no-load state, the outer diameter of the first expansion structure 21 can be greater than the outer diameter of the second expansion structure 22, so that the first expansion structure 21 and the second expansion structure 22 together form a gourd-shaped structure, and the first expansion structure 21 forms the large end of the gourd-shaped structure, which can not only prevent the adenoid stent from slipping out of the nasal cavity, but also avoid the adenoid stent from entering the nasal cavity excessively to a certain extent, thus playing a role in axially positioning the adenoid stent.

[0031] In a specific embodiment of the present disclosure, in the no-load state, the length of the second expansion structure 22 can be 8 mm - 15 mm, the length of the first expansion structure 21 can be 10 mm - 40 mm, the outer diameter of the second expansion structure 22 can be 8 mm - 15 mm, and the outer diameter of the first expansion structure 21 can be 12 mm - 28 mm. Specifically, the length of the second expansion structure 22 can be 8 mm - 12 mm, preferably 10 mm, the length of the first expansion structure 21 can be 12 mm - 20 mm, preferably 15 mm, the outer diameter of the second expansion structure 22 can be preferably 10 mm - 13 mm, and the outer diameter of the first expansion structure can be preferably 15 mm - 25 mm, so that the size of the adenoid stent adapts to the internal structure of the nasal cavity of most patients.

[0032] For the convenience of taking and placing the adenoid stent, reference is made to Figure 1 As shown, the adenoid stent may further include a fixing member 4 provided on the side of the first expansion support portion 2 away from the tubular support portion 1. When the adenoid stent is placed in the nasal cavity, the fixing member 4 can extend out of the nostril to fix the adenoid stent. Among them, the fixing member 4 can be fixed outside the nasal cavity, so as to avoid the adenoid stent from entering the nasal cavity excessively. In addition, when the adenoid stent needs to be taken out of the nasal cavity, the adenoid stent can be pulled outwards through the fixing member 4 extending out of the nostril.

[0033] In a specific embodiment of the present disclosure, the first expansion support portion 2, the second expansion support portion 3 and the tubular support portion 1 can be integrally woven and formed with silk threads, so that the first expansion support portion 2, the second expansion support portion 3 and the tubular support portion 1 form an integral mesh structure, thereby improving the use comfort.

[0034] In a specific embodiment of the present disclosure, the silk thread can be a titanium-nickel alloy silk thread, and the content of nickel can be 54.5 - 57%.

[0035] Based on the above technical solutions, the present disclosure further provides an adenoid support assembly. Reference is made to Figure 2 As shown, the adenoid support assembly includes two adenoid stents in the above technical solutions, and a connecting member 5 for connecting the two adenoid stents to each other outside the nostril.

[0036] Through the above technical solutions, the adenoid support component provided by the present disclosure has the same technical effects as the adenoid stent in the above technical solutions. To avoid unnecessary repetition, it will not be elaborated here.

[0037] In a specific embodiment of the present disclosure, referring to Figure 2 as shown, the connecting member 5 can be configured as a flexible hose, and the fixing member 4 can be a rod-shaped structure so as to be inserted and held at the end of the flexible hose, thereby connecting two adenoid stents to each other.

[0038] It should be noted here that the adenoid stent provided by the present disclosure can be used alone or in pairs to form the above adenoid support component, and the present disclosure does not limit this.

[0039] The preferred embodiments of the present disclosure have been described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0040] In addition, it should be noted that in the above specific embodiments, the various specific technical features described can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the present disclosure will not separately describe various possible combination methods.

[0041] Furthermore, any combination can be made between various different embodiments of the present disclosure, as long as it does not violate the idea of the present disclosure, and it should also be regarded as the content disclosed by the present disclosure.
