Description

Technical Field

[0001] The present invention relates to a nasal prosthesis with a split structure. Background Art

[0002] Nasal prosthesis implantation involves filling the nose with autologous tissue, foreign tissue, or tissue substitutes to elevate the external nasal volume and improve nasal appearance. Nasal implants are a commonly used cosmetic material, typically made from solid silicone rubber, polytetrafluoroethylene, and other materials.

[0003] In the prior art, Chinese Patent No. 01258164.X discloses a nasal implant implanted in a human body, which consists of a root and a tip, and the tip is hollow to form a cavity.

[0004] Chinese patent 201520668668.3 discloses a silicone nasal prosthesis. The nasal prosthesis is L-shaped and includes a nose bridge, a nose tip, and a columella section, and a plurality of transverse incisions are provided on the nose bridge.

[0005] Chinese Patent No. 01237585.3 discloses a rhinoplasty implant, which comprises an L-shaped solid silicone rubber implant with an expanded polytetrafluoroethylene coating at the angled portion thereof, covering the outer surfaces and both side surfaces of the long and short arms. The silicone rubber nose mold is tightly fitted to the coated expanded polytetrafluoroethylene and fixed with surgical sutures or adhesives, forming a single unit.

[0006] The tip and dorsum of the nasal prosthesis in the prior art are designed with an integral structure, and the size needs to be determined according to the user. During use, the tip and dorsum of the nose cannot be adjusted relative to each other. In addition, the nose head in the prior art is divided into a flat head structure, which is prone to separation at the connection position, resulting in poor docking and disconnection, affecting the postoperative effect.

[0007] Based on this, the present application provides a nasal prosthesis based on a split structural design and with good connection effect. Summary of the Invention

[0008] In view of the defects of the prior art, the present invention provides a nasal prosthesis with a tuck connection portion at the nasal dorsum to provide a connection space and have the advantage of a good connection effect.

[0009] In order to achieve the above object, the present invention provides a nasal prosthesis, including a nasal dorsum portion, the nasal dorsum portion at least comprising:

[0011] The first connecting section is located at one side of the nasal dorsum section and is connected to the nasal dorsum section as a whole, wherein at least one inwardly recessed shingle connection portion is formed on the inner side of the first connecting section.

[0012] In the above technical solution of the present invention, the nasal dorsum section is willow-leaf-shaped and serves as the nose bridge. The first connecting section is used to cooperate and fix with the support frame, wherein the support frame is usually autologous cartilage or other materials. By providing an inwardly recessed shingle connection portion in the first connecting section, on the one hand, the support frame can be hidden, and on the other hand, a certain space can be provided for tissue filling after implantation, thereby forming a better connection.

[0013] According to another specific embodiment of the present invention, the shoe connection portion has a first opening, and the nose tip support inserted into the shoe connection portion can move along a first direction within the first opening.

[0014] According to another specific embodiment of the present invention, the shoe connection portion has a second opening, and the nose tip support inserted therein can move in the second opening along a second direction, wherein there is an inclination angle between the first direction and the second direction.

[0015] According to another specific embodiment of the present invention, the first opening and the second opening are communicated with each other, and the nose tip support inserted into the shoe connection portion can move along the second direction while moving along the first direction.

[0016] According to another specific embodiment of the present invention, the shoe connection portion gradually expands outwards along its bottom toward the first opening to form a flared opening, and the shoe connection portion gradually expands outwards along its bottom toward the second opening to form a flared opening.

[0017] According to another specific embodiment of the present invention, the depth H1 of the shingle connection at its first opening is 0.5-1.5 cm, and the depth H2 of the shingle connection at its second opening is 0.3-0.8 cm, wherein the depth H1 is set to be no less than the depth H2.

[0018] According to another specific embodiment of the present invention, the present invention further includes a nose tip portion, which includes:

[0019] columellar segment;

[0020] The nose tip section is curved, and the columella section is connected to one side of the nose tip section and is integrated with the nose tip section;

[0021] The second connecting section is located at the other side of the nose tip section and is connected to the nose tip section as a whole, wherein a shoe fitting portion for plugging and fitting with the shoe fitting portion is formed at a free end of the second connecting section.

[0022] According to another specific embodiment of the present invention, the shoe fitting portion has at least two outwardly extending fitting arms, and the two fitting arms inserted into the shoe connection portion are restricted and tightly attached to the shoe connection portion.

[0023] According to another specific embodiment of the present invention, inwardly concave frills are provided on both sides of the columella section of the nose tip section, and the frills and the nose tip section enclose a canopy connecting groove.

[0024] According to another specific embodiment of the present invention, the outer side of the nose tip section is recessed inward to form a groove.

[0025] The present invention has the following beneficial effects:

[0026] The nose dorsum of the present invention is provided with a connecting portion for connection, which reduces the difficulty of implantation, causes less trauma during the operation, and achieves a better connection effect;

[0027] In addition, the first opening and / or the second opening provided in the nasal dorsum of the present invention can provide a certain range of space, which forms a soft fit with the support frame (nose tip prosthesis part), on the one hand reducing the difficulty of implantation during surgery, and on the other hand being more adaptable to the user, forming a better attachment effect, and having good stability after the user's tissue is filled;

[0028] The nose dorsum and nose tip parts of the present invention adopt a separate structure, and the nose dorsum and nose tip parts are plug-fitted and connected, with smooth docking and a smooth transition at the docking point, which reduces the difficulty of implantation and minimizes the trauma of the surgical process.

[0029] In addition, an inward-concave ruffle is set at the tip of the nose. The ruffle and the tip of the nose are combined to form a canopy connection groove. On the one hand, the canopy connection groove can cover the connection part, and on the other hand, it can allow tissue filling. Even if the material separates, it will not affect the postoperative effect.

[0030] The present invention will be described in further detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] A nasal prosthesis, such as Figure 1 -6, including a nose back portion 100 and a nose tip portion 200.

[0038] The nose dorsum portion 100 is as shown in FIG. Figure 1 As shown, it includes a nasal dorsum segment 110 and a first connecting segment 120, wherein the nasal dorsum segment 110 is willow-leaf-shaped as a whole, and an anti-slip protrusion / groove structure 130 is provided on the outer side and / or inner side of the nasal dorsum segment 110; the first connecting segment 120 is located on one side of the nasal dorsum segment 110 and is connected to the nasal dorsum segment 110 as a whole, wherein at least one inwardly recessed shingle connection portion 140 is formed on the inner side of the first connecting segment 120.

[0039] Nose tip portion 200 Figure 2-3 As shown, the nose tip section 220 includes a columella section 210, a nose tip section 220, and a second connecting section 230. The nose tip section 220 is curved. The columella section 210 is connected to one side of the nose tip section 220 and is connected to the nose tip section 220 as a whole. The second connecting section 230 is located on the other side of the nose tip section 220 and is connected to the nose tip section 220 as a whole. An angle α of 50° to 90° is formed between the connecting section and the columella. For example, Figure 3 The angle α in is 60°;

[0040] A shoe fitting portion 240 that is plug-fitted with the shoe connection portion 140 is formed at the free end of the second connecting section 230 .

[0041] like Figure 4 As shown in FIG. 5 , the shoe connection portion 140 has a first opening 141 and a second opening 142 that are connected to each other and a shoe groove is formed in the shoe connection portion 140. The shoe fitting portion 240 inserted into the shoe groove can move in a small range along the first direction X and the second direction Y respectively to form a plug-in fit (loose fit). Compared with a one-piece nasal prosthesis, the split structure reduces the difficulty of implantation on the one hand and is more adaptable to the user on the other hand.

[0042] Specifically, the depth H1 of the shingle connection portion 140 at its first opening 141 is 0.5-1.5 cm, for example, 1.0 cm, and the depth H2 of the shingle connection portion 140 at its second opening 142 is 0.3-0.8 cm, for example, 0.5 cm, wherein the depth H1 is set to be no less than the depth H2.

[0043] The depth here refers to the distance from the first opening and the second opening to the farthest inner wall thereof.

[0044] Furthermore, the tread connection portion 140 gradually flares outward along its bottom toward the first opening 141 to form an outward-flashing opening, and the tread connection portion 140 gradually flares outward along its bottom toward the second opening 142 to form an outward-flashing opening. This outward-flashing structure makes it easier to form a good plug-in relationship with the tread fitting portion 240, facilitating the progress of the operation and postoperative recovery.

[0045] A specific structure of the shoe fitting portion 240 is as follows: Figure 2 As shown:

[0046] The shoe fitting portion 240 has two outwardly extending fitting arms 241. The two fitting arms 241 inserted into the shoe connection portion 140 are restricted and tightly attached to the shoe connection portion 140. A relatively fixed fitting relationship will be formed through growing tissue within a period of time after the operation.

[0047] Another specific structure of the shoe fitting portion 240 is as follows Figure 6 As shown:

[0048] The shoe fitting portion 240 is formed with comb-tooth-shaped side edges 242 , which are inserted into the shoe connection portion 140 for contact connection, and a relatively fixed fitting relationship is formed by growing tissue within a period of time after the operation.

[0049] In the present invention, the nose tip section 220 has an inwardly concave ruffle 221, which encloses the nose tip section 220 to form a rain canopy connection groove 222, wherein the ruffle 221 preferably extends from the second connecting section 230 through the nose tip section 220 to the columella section 210;

[0050] Furthermore, the outer side of the nose tip section 220 is inwardly recessed to form at least one groove 223, so that the nose tip section 220 and human tissue can grow together better and prevent sliding.

[0051] In other examples of the present invention, only the first opening or the second opening in a single direction can also nearly achieve the technical effect of the present invention, which will not be described in detail here.

[0052] Any matters not mentioned above are applicable to the existing technology.

[0053] The nose dorsum portion 100 in the present invention can be used alone, for example, in conjunction with a traditional support frame, and can still achieve the technical effects of the present invention.

[0054] Although the present invention is disclosed above with reference to preferred embodiments, this is not intended to limit the scope of the present invention. Any person skilled in the art may make slight modifications without departing from the scope of the present invention. In other words, any equivalent modifications made in accordance with the present invention should be included within the scope of the present invention.
