Furthermore, the use of autologous cartilage makes it easier to sculpt and provides support tailored to the user.

Description

Technical Field

[0001] This utility model relates to the field of rhinoplasty design, and more particularly to a multi-segment expandable nose. Background Technology

[0002] The segmented rhinoplasty technique divides the nose into different parts, such as the columella, tip, and bridge, and then uses the most suitable surgical methods and materials for each part. This technique emphasizes overall design and comprehensive shaping, focusing not only on the height and upturn of the nose, but also on the overall aesthetics of the nose and its harmony with the face.

[0003] Currently, segmented rhinoplasty has been widely used in clinical practice and has achieved significant results. Many patients have improved their nasal shape and enhanced their overall facial aesthetics through segmented rhinoplasty. Traditional multi-segment techniques often involve creating multiple segments from an implant, followed by simple suturing, and finally implanting them into the patient's nasal cavity. While this method has some effectiveness, it also has the following drawbacks:

[0004] Traditional multi-segment expanded nose implants use pure silicone implants at the tip of the nose. Due to their hardness, prolonged wear can easily cause discomfort for users. The columella segment also uses traditional silicone implants, resulting in insufficient support and potential dislodgement, which greatly affects the cosmetic outcome. The segments of traditional expanded nose implants are often connected by simple sutures, leading to poor resistance to displacement and insufficient stability, making them prone to breakage within the nasal cavity and posing a certain risk to users. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this invention is to provide a molded multi-segment inflatable nose.

[0006] The following technical solution is adopted: a multi-segment expandable nose includes a columellar segment, a nasal tip segment at the top of the columellar segment, and a nasal bridge segment on one side of the nasal tip segment.

[0007] Optionally, a retaining strip is fixedly provided at the top of the columellar segment, and a slot is provided inside the retaining strip.

[0008] Optionally, the bottom end of the nasal tip segment has a through-hole and a slot, the locking strip engages with the slot, a positioning bolt is engaged with the inner wall of the slot, and the columellar segment and the nasal tip segment are fixedly connected by the positioning bolt.

[0009] Optionally, the inner wall of the nasal tip segment is provided with a second groove, the inside of the nasal bridge segment is provided with a first groove, and a suture is sleeved between the first groove and the second groove.

[0010] Optionally, the nasal tip segment is provided with an internal implant, both the nasal tip segment and the nasal bridge segment are made of silicone material, and both the columella segment and the internal implant are made of autologous cartilage material.

[0011] Optionally, the number of the card strip, card slot, positioning pin, and slot are several, and they are distributed in a circular array centered on the reference axis of the columellar segment.

[0012] Optionally, the number of sutures, the first groove, and the second groove are each several, and they are distributed in a circular array centered on the nasal bridge segment reference axis.

[0013] Optionally, the suture is made of high-strength polypropylene material.

[0014] The technical effects that can be achieved by the technical means of this utility model are as follows:

[0015] (1) In this utility model, by setting an internal implant in the nasal tip segment, the internal implant is composed of autologous cartilage material, abandoning the traditional pure implant production, so that the nasal tip segment becomes a composite structure of implant and autologous cartilage, which can give users a better sense of touch. At the same time, the use of autologous cartilage makes it easier to sculpt and provides support that adapts to the user.

[0016] (2) In this utility model, by setting the columella segment, the completely silicone prosthesis is abandoned and replaced with autologous cartilage material, which can provide more accurate length and thickness calculation before implantation, thereby providing stronger support and stabilizing the structure of the nasal tip.

[0017] (3) In this utility model, by setting up sutures and positioning bolts, and using two methods, namely positioning bolts and slots for snapping and suture stitching, the traditional simple stitching is replaced, which has stronger anti-displacement ability and stability.

[0023] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0024] In the description of this utility model, it should be noted that the orientations or positional relationships indicated by terms such as "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end" are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] A preferred embodiment of the multi-segment inflatable nose provided by this utility model is, for example... Figures 1 to 4 As shown: A multi-segment expandable nose includes a columellar segment 1, a nasal tip segment 2 at the top of the columellar segment 1, and a nasal bridge segment 3 on one side of the nasal tip segment 2.

[0027] In this embodiment, a retaining strip 4 is fixedly provided at the top of the columellar segment 1, and a slot 7 is provided through the inside of the retaining strip 4. A retaining groove 5 is provided through the bottom of the nasal tip segment 2. The retaining strip 4 and the retaining groove 5 are engaged. A positioning bolt 6 is engaged in the inner wall of the slot 7. The columellar segment 1 and the nasal tip segment 2 are fixedly connected by the positioning bolt 6. A second groove 10 is provided through the inner wall of the nasal tip segment 2. A first groove 9 is provided through the inside of the nasal bridge segment 3. A suture 8 is sleeved between the first groove 9 and the second groove 10. The number of retaining strips 4, grooves 5, positioning bolts 6 and slots 7 are several, and they are arranged in a circular array with the nasal columellar segment 1 as the center. The number of sutures 8, first grooves 9 and second grooves 10 are several, and they are arranged in a circular array with the nasal bridge segment 3 as the center. The suture 8 is made of high-strength polypropylene material.

[0028] The above scheme, by setting the columellar segment 1, abandons the use of pure silicone implants and replaces them with autologous cartilage material. This allows for more precise length and thickness calculations before implantation, thus providing stronger support and stabilizing the nasal tip structure. By setting sutures 8 and positioning plugs 6, and using two methods—positioning plugs 6 and slots 7 for engagement and sutures 8 for stitching—it replaces the traditional simple suturing, resulting in stronger resistance to displacement and stability.

[0029] In this embodiment, the nasal tip segment 2 is provided with an internal implant 11, the nasal tip segment 2 and the nasal bridge segment 3 are both made of silicone material, and the columella segment 1 and the internal implant 11 are both made of autologous cartilage material.

[0030] The above solution involves placing an internal implant 11 within the nasal tip segment 2. The internal implant 11 is composed of autologous cartilage material, which eliminates the need for traditional pure implant manufacturing. This transforms the nasal tip segment 2 into a composite structure of implant and autologous cartilage, providing users with a better tactile experience. Furthermore, the use of autologous cartilage makes it easier to sculpt and provides support tailored to the user.

[0031] Working principle: When operating and using this utility model, as follows... Figures 1 to 4 As shown, the installation process is as follows: the clip 4 is inserted into the slot 5, and then the positioning bolt 6 is inserted into the slot 7 to fix the columellar segment 1 and the nasal tip segment 2. Then, the suture 8 is used to sew through the first groove 9 and the second groove 10 to connect the nasal tip segment 2 and the nasal bridge segment 3.

[0032] Function: By placing an internal implant 11 within the nasal tip segment 2, the internal implant 11 is composed of autologous cartilage material, abandoning the traditional pure implant manufacturing process. This transforms the nasal tip segment 2 into a composite structure of implant and autologous cartilage, providing the user with a better tactile experience. At the same time, the use of autologous cartilage makes it easier to sculpt and provides support tailored to the user. By setting the columella segment 1, the use of autologous cartilage material instead of a completely silicone implant allows for more precise length and thickness calculations before implantation, thus providing stronger support and stabilizing the nasal tip structure. By setting sutures 8 and positioning plugs 6, the two methods of positioning plugs 6 and slots 7 are used for engagement, and sutures 8 are used for suturing, replacing the traditional simple suturing method, resulting in stronger resistance to displacement and stability.

[0033] The above are merely illustrative embodiments of this utility model and are not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification of this utility model can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
