[0030] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0031] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0032] This embodiment provides a fixation device for rhinoplasty surgery, one possible implementation of which is:

[0033] See Figure 4The postoperative fixation device includes a shaping piece 1 for shaping the outside of the nose and a support frame 2 for supporting the inside of the nose, as well as a fixation frame 3. The shaping piece 1 has a heated softening state and a room-temperature hardening state. During operation, the shaping piece 1 is in the hardened state and fits against the bridge of the nose. The two sides of the fixation frame 3 clamp the two sides of the shaping piece 1 and can hold and fix the shaping piece 1 to the bridge of the nose. The support frame is used to insert into the nasal cavity and provide support from the inside. The width of the fixation frame 3 can be slightly smaller than the width of the bridge of the nose, so that when the fixation frame 3 is inserted into the two sides of the bridge of the nose, it can form a clamping fixation with the nose, thereby fixing the shaping piece 1. The clamping parts on both sides of the fixation frame 3 can be set to have a certain degree of elasticity. When inserted into the two sides of the bridge of the nose, it opens and deforms outward to form an elastic clamping force, and the clamping distance can automatically adapt to the width of the nose, making the clamping more stable. It should be noted that in actual operation, the support frame 2 can be placed into the nasal cavity for support first, and then the shaping piece 1 and the fixation frame 3 are installed on the bridge of the nose to avoid affecting the shape of the nose during the operation. The support frame 2 includes a first support tube 21, a second support tube, and a connecting piece 23. During operation, the first support tube 21 and the second support tube are inserted into the nostril, and the connecting piece 23 is disposed at the end of the support tube and connects the first support tube 21 and the second support tube into one unit. The shaping piece 1 can be a low-temperature thermoplastic sheet.

[0034] In the above embodiments, the shaping sheet 1 (low-temperature thermoplastic plate) is a medical material made from a specially synthesized high-molecular polyester through a series of physical and chemical processes. It is commonly used in the manufacture of orthopedic external fixation devices, braces, and orthotics. In this embodiment, the shaping sheet 1 is used to adhere to and support the back of the shaped nose. When using it, the low-temperature thermoplastic plate material is placed in hot water at 60-70℃ to completely soften it, and then removed. The completely softened material is placed on the bridge of the nose, spread evenly, and then shaped according to the shape of the human nose bridge. The shaping process takes 3-5 minutes. After shaping, wait 5-10 minutes for it to fully harden and set. If the room temperature is too high or the setting time is too long, a cool air blower can be used to accelerate the cooling and hardening process. After hardening and setting, it is adhered to the bridge of the nose and fixed there. Medical tape or a fixation frame 3 can be used. The fixation frame 3 can clamp the shaped sheet 1 from both sides to keep it fixed to the bridge of the nose.

[0035] The first support tube 21 and the second support tube of the support frame 2 are inserted into the nostrils respectively, providing support from the inside. The outer wall of the support tube and the inner wall of the shaping piece 1 support and shape the nose from both the inside and outside, ensuring support effectiveness and stability. This dual support structure not only enhances the stability of the nasal shape but also allows for personalized adjustments based on the patient's nasal characteristics, ensuring a precise and fitting support effect. Furthermore, this design reduces nasal discomfort caused by uneven external pressure, improves the patient's user experience, and provides a more reliable guarantee for post-rhinoplasty recovery.

[0036] When the user wears the support bracket 2 in the nostril, the connecting piece 23 between the two support tubes is located on the outside of the nasal septum. Its function is to facilitate the removal of the support bracket 2 from the nostril. On the other hand, it also plays a positioning and limiting role to prevent the support tube from entering too deep into the nostril.

[0037] Please refer to this embodiment. Figure 3 and Figure 4 When the shaping piece 1 is in working condition, a clamping structure is formed in the areas on both sides of the nasal bridge for the fixing frame 3 to hold it in place. The purpose of this structure is to facilitate the fixing frame 3 in securing the shaping piece 1 to the nasal bridge. In one possible embodiment, the fixing frame 3 is a U-shaped metal strip, which can be made of lightweight aluminum. The two sides of the metal strip contact the shaping piece 1 and clamp it to the outside of the nose. The two sides of the metal strip have a certain elasticity relative to the bottom strip, and inserting it into the sides of the nose creates a clamping force. Specifically, the clamping structure can be varied; it could be holes or grooves on the shaping piece 1 into which the two sides of the metal strip are inserted to form a secure connection; or it could be a bend shaped on both sides of the shaping piece 1. In short, anything that allows the two sides of the metal strip to create a clamping force is sufficient.

[0038] Based on the above embodiments, in this embodiment, arc-shaped pieces 30 are provided on both sides of the fixed frame 3. The inner arc side of the arc-shaped piece 30 is fixed to the fixed frame 3, and the outer arc surface contacts the nose. The arc-shaped piece 30 is used to increase the contact area, increase the clamping effect, reduce local stress, and improve the clamping effect.

[0039] Based on the above embodiments, in this embodiment, the first support tube 21 and the second support tube have the same structure, with one end near the connecting piece 23 being the head end and the other end being the tail end. From the head end to the tail end, the outer diameter of the support tube first increases to form a bulge area 211, and then gradually decreases until it reaches the tail end. The change in the cross-sectional diameter of the support tube is to adapt to the structure of the human nostril, ensuring a good fit and comfort. For details, please refer to [reference needed]. Figure 7 .

[0040] Based on the above embodiments, in this embodiment, at the bulge area 211 of the support tube, a plurality of protruding support rings 2112 are circumferentially arranged, or a plurality of protruding support points 2113 are distributed in a ring shape. See also... Figure 1 In order to reduce the number of attached figures, Figure 1 In the diagram, the bulging area 211 of one of the support tubes illustrates the structure of the support ring 2112, and the bulging area 211 of the other support tube illustrates the structure of the support point 2113.

[0041] In the above embodiments, the functions of the support ring 2112 and the support point 2113 are both to improve comfort and reduce long-term local support. Regarding the support ring 2112, the rings are staggered to avoid the entire surface fitting together, which could cause local pressure, impede blood flow, and affect postoperative recovery and user experience. Simultaneously, the back-and-forth movement of the support tube within the nostril allows the support ring area to change, thus altering the support position inside the nostril. The principle and effect of the support point 2113 are similar, but the support point 2113 is more effective because the support area can change more easily and frequently.

[0042] Please refer to this embodiment. Figure 7 The first support tube 21 and / or the second support tube include an inner ring 212 and an outer bladder 213. The two sides of the outer bladder 213 are respectively connected to the two sides of the inner ring 212 to form an annular cavity space. The degree of bulging of the outer bladder 213 relative to the inner ring 212 is adjusted by the pressure of the annular cavity space. A valve 214 for charging and discharging pressure is provided on the wall of the cavity space.

[0043] In the above embodiments, the inflation and deflation of the support tube can be adjusted by inflating and deflating the valve 214, so that different users can adjust the air pressure according to their nostril size and feelings, thereby ensuring comfort; in addition, the outer capsule 213 can fit more tightly into the irregular space inside the nostril, ensuring the user experience and preventing it from loosening or even shaking inside the nostril; furthermore, the inflatable mode is lighter than the solid mode, making it more comfortable for the user to wear.

[0044] For this embodiment, please refer to Figure 1 A pull tab 231 is provided in the middle of the connecting piece 23. The pull tab 231 is located on the lower side when worn and can be used to indicate the wearing direction. In addition, combined with Figure 4 and Figure 5 The fixing frame 3 is provided with a groove, and the pull tab 231 can pass through the groove and be fixedly connected to the fixing frame 3 as a whole, which can be achieved by screws; thereby increasing the stability and integrity of the entire support device.
