Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an adjustable nasal root external splint. Background Art

[0002] In the early stage after rhinoplasty, dynamic changes in the recovery period, such as swelling, scar hyperplasia, absorption of accumulated blood and fluid, and changes in cartilage support, may lead to problems such as early instability of the constructed cartilage scaffold, deviation of the implanted nasal prosthesis, and deformation of the cartilage scaffold. Clinically, these problems are manifested as deformation of the nose tip, nose bridge, and nasal root, and deviation of the prosthesis, which may lead to dissatisfaction after surgery, rework, and even surgical failure. In order to prevent the occurrence of the above situation during the postoperative recovery period, we use an external nasal splint for fixation after rhinoplasty. It has a significant protective effect to avoid postoperative instability caused by external force or endogenous changes. It helps maintain the symmetry of the nasal dorsum. Since the nasal dorsum prosthesis has not been completely fitted and fixed in the early stage of surgery, the use of a nasal splint after surgery can better prevent the deviation of the prosthesis caused by external force or changes in the recovery period. In the early stage after surgery, a nasal splint with good fit can effectively limit the swelling of the nasal dorsum, nasal root, and nasal tip, reduce blood and fluid accumulation in the surgical area, and facilitate faster recovery after surgery.

[0003] In the prior art, aluminum plates and thermoplastic plates with adhesive backings (thermoplastic plates are materials that are softened and shaped by heating) are usually used to fix the nose. However, since adhesive or tape is used, these products cannot fix the root of the nose well when fixing the nose or cheeks, and they have no elasticity and pressure. They are also troublesome to wear and are not suitable for patients with sensitive skin. Most patients develop allergic reactions due to long-term contact of their skin with tape, so they cannot insist on wearing the products for a long time. Secondly, since it is necessary to fix the bridge of the nose and compress swelling and prevent hyperplasia and deformation of the bridge of the nose after surgery, these products are hard and can only be larger than or equal to the size of the bridge of the nose when worn on the bridge of the nose. They cannot fit the nose and cannot put pressure on the nose. In addition, the nose is in a swollen period after surgery, and the product will loosen after the swelling of the bridge of the nose subsides, losing its fixing effect. Utility Model Content

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-7 , the utility model embodiment includes:

[0029] An adjustable external nasal root splint comprises a contoured splint body 1, a stabilizing strip 2, a fixing plug-in 3 and an elastic binding (elastic) belt 4.

[0030] The contoured splint body adopts a flexible structure with resilience (can be made of silicone material, rubber material, etc.) to wrap the bridge of the nose and both sides of the root of the nose. Since the angle of the product needs to be adjusted according to the angle between the root of the nose and the bridge of the nose of each person during use, splint openings 10 are provided on both sides of the contoured splint body to reduce the tension of the silicone material when adjusting the angle, so that the contoured splint body will not rebound after the angle is adjusted.

[0031] The contoured splint body can be made in one or more different sizes to accommodate different sizes of patient's noses. For example, the size settings can be small, medium and large, or female and male. Alternatively, the sizes can be set to small, medium and large for male and female noses, respectively.

[0032] Further preferably, the main body of the contoured splint is an arched structure so as to fit the part to be wrapped for use.

[0033] Further preferably, the contoured splint body includes a first splint (contacting and fixed to the upper part of the nose) 12 and a second splint (contacting and fixed to the lower part of the nose) 13 integrally connected to the main body spine 11, and both sides of the first splint and the second splint are symmetrical structures, and the area of ​​the first splint is smaller than that of the second splint.

[0034] Further preferably, the first clamping plate is connected to the second clamping plate, and the clamping plate opening is arranged on the outer side of the connection between the first clamping plate and the second clamping plate.

[0035] Further preferably, since the nose wing is arc-shaped and protrudes outward, some surgical procedures may cause wounds on the edge of the nose wing. Therefore, the lower edge (second splint) of the contoured splint body is set as an arc angle structure 14, so that when the patient wears the product, the nose wing will not be pressed, and the wound recovery will not be affected.

[0036] Further preferably, since the root of the nose is located between the two eyes, the two sides of the bottom of the contouring splint body are symmetrical arc angles 15 .

[0037] The main body spine of the contoured splint body is provided with a first retaining hole 16, a second retaining hole 17 and a third retaining hole 18, and the bendable stabilizing strip is embedded in the middle position of the main body spine, that is, the stabilizing strip is wrapped in silicone material. The stabilizing strip is provided with a first positioning hole 21, a second positioning hole 22 and a third positioning hole 23, respectively, and the first positioning hole, the second positioning hole and the third positioning hole are connected to the first retaining hole, the second retaining hole and the third retaining hole in a one-to-one correspondence. The retaining holes and the positioning holes are connected and matched with each other, and they mainly play two roles: one is to fix the mold during production to prevent the position of the stabilizing strip from shifting during production, and the other is to cooperate with the fixing plug-in and the elastic band.

[0038] Further preferably, the stabilizing bar is an aluminum alloy structure and has a certain curvature. The aluminum alloy is plastic, and the stabilizing bar can be manually moved when worn to adjust the angle of the angle adjustment area 24 of the contoured splint body, and the contoured splint body can be positioned at a fixed angle after deformation to prevent the main shape of the silicone material from rebounding, so that the contoured splint body can better fit the patient's nose.

[0039] The upper part of the fixing plug-in is provided with an elastic band connecting hole 31 for fixing the elastic band to prevent displacement, the lower part of the fixing plug-in is provided with a retaining slot 32, and the bottom thereof is provided with a limiting buckle 33 with deformation and rebound capabilities, the lower part of the fixing plug-in is inserted into the retaining hole, and the limiting buckle passes through the positioning hole and is movably connected to the bottom of the retaining hole to clamp the stabilizing bar, so that the stabilizing bar is clamped in the retaining slot, thereby fixing the fixing plug-in to the stabilizing bar and the contoured splint body.

[0040] When installing the fixing plug-in, insert the fixing plug-in into the second retaining hole. At this time, the second positioning hole on the stabilizing bar is just located at the retaining slot position, and the limiting buckle is located below the stabilizing bar. In this way, the fixing plug-in will not be displaced or fall off during use, and it is safer and more convenient for patients to use.

[0041] When in use, first pass the elastic band through the elastic band connecting hole, then insert the fixing plug-in into the retaining hole, and then adjust the angle of the contour splint body according to the angle between the patient's nasal root and the nose bridge, so that it can be worn at a suitable angle; since the first splint and the second splint are both made of silicone material and have a certain resilience, when pressure is applied inwards under the elastic action of silicone, the contour splint body can be made to fit closely to the nasal root and both sides of the nose bridge, and can be adjusted according to different periods after rhinoplasty (swelling period and hyperplasia period) to make the nasal root and the nose bridge bear force more evenly, thereby promoting swelling reduction through physical compression and preventing the occurrence of hyperplasia.

[0042] The beneficial effects of the adjustable nasal root external splint of the utility model are:

[0043] 1. It solves the problem of inconvenience in fixing the bridge of the nose and the root of the nose after existing rhinoplasty surgery. It can be fixed on the nose more accurately and stably, so that the nose is stressed and the nose swelling is promoted. It can also meet the wearing requirements of different periods, has strong adaptability, and can more effectively promote the skin to reattach to the reconstructed bridge of the nose bone. It is simple to use and easy to wear.

[0044] 2. The product is fixed to the back of the patient's neck through a rope or elastic band, which avoids the pain of using tape for patients with sensitive skin.

[0045] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
