Description

Technical Field

[0001] This utility model relates to the field of plastic and cosmetic surgery technology, and in particular to a nasal prosthesis. Background Technology

[0002] Rhinoplasty is one of the most common cosmetic surgeries. The nasal implant, as a crucial component in this procedure, directly impacts the surgical outcome and postoperative appearance through its shape and material. Traditional nasal implants are often L-shaped or willow-leaf shaped, as illustrated by the published patent: "A Nasal Plastic Implant," publication number CN215307035U, which discloses a nasal plastic implant with an L-shaped structure. However, traditional nasal implants have the following drawbacks: 1. The nasal dorsum section of traditional implants is generally straight, resulting in a limited shape and difficulty in meeting individual needs; 2. Traditional nasal implants have the same width from top to bottom, which can lead to a noticeable, stiff, and rigid appearance, especially in patients with thin skin, lacking a natural aesthetic; 3. Whether L-shaped or willow-leaf shaped, the starting point and highest point are located at the nasal root, failing to reach the glabella and thus hindering the creation of a well-defined double-C shape in the nasofrontal-glabellar triangle; 4. Surgeons typically sculpt nasal implants from rectangular blocks of expanded polytetrafluoroethylene (ePTFE), requiring considerable sculpting skill. Utility Model Content

[0003] In view of the above-mentioned shortcomings of traditional nasal implants, this utility model provides a nasal implant that has a stronger aesthetic appeal and meets personalized needs.

[0004] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions:

[0005] According to one aspect of the present invention, a nasal prosthesis is provided, comprising a fishtail segment and a nasal bridge segment formed integrally, wherein the fishtail segment is an inverted triangular fishtail structure, and both sides of the fishtail segment are connected to both sides of the nasal bridge segment by an arc transition, wherein a camel hump curve is formed at the top of the nasal bridge segment, and the highest point of the camel hump curve is located in the front middle part of the nasal bridge segment.

[0006] Optionally, the lateral width of the junction between the fishtail segment and the nasal bridge segment is smaller than the lateral width of the rest of the nasal prosthesis.

[0007] Optionally, the arc of the connection between the fishtail segment and the nasal bridge segment is a C-shape with the opening facing outwards, and the C-shapes on both sides are symmetrically arranged to form a concave repair structure in the glabella triangle area.

[0008] Optionally, the sides of the nasal dorsum segment form arcs, which are parabolas starting from the end of the nasal dorsum segment and ending at the nasal tip segment at the front end of the nasal dorsum segment.

[0009] Optionally, the hump curve at the top of the nasal dorsum segment transitions smoothly with the nasal tip segment.

[0010] Alternatively, the nasal prosthesis may be a component made of expanded polytetrafluoroethylene.

[0011] Alternatively, the nasal prosthesis may be a single piece of material sculpted by CNC machining.

[0012] The advantages of this invention are as follows: The overall shape of the nasal implant provided by this invention is very different from that of traditional L-shaped or willow-leaf shaped nasal implants. The sides of the nasal dorsum section have smooth arcs, making the nose more natural and avoiding a stick-like appearance. The connection between the fishtail section and the nasal dorsum section is transitioned by a C-shaped arc, which is used to form a concave repair structure in the glabella triangle area. The top of the nasal dorsum section forms a camel hump curve, making the nose more three-dimensional. It can be seen that the nasal implant provided by this invention has a stronger aesthetic appeal compared to traditional nasal implants. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1

[0020] according to Figures 1-3As shown, a nasal prosthesis includes a fishtail segment 1 and a nasal dorsum segment 2 formed as one piece. The fishtail segment 1 is an inverted triangular fishtail structure. The two sides of the fishtail segment 1 are connected to the two sides of the nasal dorsum segment 2 by an arc transition. The top of the nasal dorsum segment 2 forms a camel hump curve, and the highest point of the camel hump curve is located in the anterior middle part of the nasal dorsum segment 2.

[0021] Specifically, the top of the nasal dorsum segment 2 forms a camel hump curve, simulating the shape of a natural nose. The highest point of the camel hump is slightly higher than the tip of the nose at the front of the nasal dorsum segment 2, and it transitions smoothly with the tip of the nose, avoiding the stiffness of traditional implants. The length ratio of the fishtail segment 1 to the nasal dorsum segment 2 is 1:2.5-3.5. The highest point of the camel hump curve deviates from the middle and is forward by 0.5-1.5mm, forming a natural nasofrontal angle with a curve radius of 15-25mm. The lines of the nasal implant transition naturally and smoothly, and the arc from the glabella to the nasal dorsum segment 2 and from the highest point of the camel hump to the tip of the nose is smoother, resulting in a more natural postoperative effect.

[0022] Example 2

[0023] according to Figures 1-3 As shown, a nasal implant includes a fishtail segment 1 and a nasal dorsum segment 2 formed as one piece. The fishtail segment 1 is an inverted triangular fishtail structure. The two sides of the fishtail segment 1 are connected to the two sides of the nasal dorsum segment 2 by an arc transition. The top of the nasal dorsum segment 2 forms a camel hump curve. The highest point of the camel hump curve is located in the anterior middle part of the nasal dorsum segment 2. The arc of the connection part between the fishtail segment 1 and the nasal dorsum segment 2 is a C-shaped opening with the opening facing outward. The C-shapes on both sides are symmetrically arranged to form a depression repair structure in the glabella triangle area.

[0024] Specifically, the fishtail section 1 has an inverted triangular structure, and the transition to the bridge of the nose section 2 adopts a double C-line design to make the glabella fuller. The double C-lines are two symmetrical parabolas that form a concave repair structure in the triangle area between the eyebrows. The distance between the two lines is 15-25mm. The transition from the fishtail section 1 to the bridge of the nose section 2 can create a three-dimensional effect of the double C-lines. The bridge of the nose section is slightly raised near the middle to create a three-dimensional and layered effect on the bridge of the nose.

[0025] Example 3

[0026] according to Figures 1-3 As shown, a nasal implant includes a fishtail segment 1 and a nasal dorsum segment 2 formed as one piece. The fishtail segment 1 has an inverted triangular fishtail structure. The two sides of the fishtail segment 1 are connected to the two sides of the nasal dorsum segment 2 by an arc transition. The top of the nasal dorsum segment 2 forms a camel hump curve. The highest point of the camel hump curve is located in the front middle part of the nasal dorsum segment 2. The lateral width of the connection part between the fishtail segment 1 and the nasal dorsum segment 2 is smaller than the lateral width of the rest of the nasal implant.

[0027] Specifically, the nasal implant has an overall shape that varies in width. The narrowest point is where the fishtail segment 1 connects to the nasal dorsum segment 2. It then widens at the junction of the cartilage and hard bone, and narrows again near the tip of the nose. The width of the fishtail segment is 4-8mm, the widest point of the nasal dorsum segment is 8-12mm, and the width of the nasal tip segment is 6-10mm, making the overall appearance more natural.

[0028] Example 4

[0029] according to Figures 1-3 As shown, a nasal prosthesis includes a fishtail segment 1 and a nasal dorsum segment 2 formed as one piece. The fishtail segment 1 is an inverted triangular fishtail structure. The two sides of the fishtail segment 1 are connected to the two sides of the nasal dorsum segment 2 by an arc transition. The top of the nasal dorsum segment 2 forms a camel hump curve, and the highest point of the camel hump curve is located in the anterior middle part of the nasal dorsum segment 2. The two sides of the nasal dorsum segment 2 form arcs, which are parabolas starting from the end of the nasal dorsum segment and ending at the nasal tip segment at the front end of the nasal dorsum segment. The camel hump curve at the top of the nasal dorsum segment 2 transitions smoothly with the nasal tip segment.

[0030] Specifically, the lateral contour of the nasal bridge section adopts an arc design, which can fit more closely with the lateral nasal angle and avoid a stick-like appearance. The fitting angle with the lateral nasal angle is 30-45 degrees. The height difference of the camel hump curve is 1.5-3.5mm, and the slope from the highest point to the tip of the nose is 1:4-1:6, making the appearance contour more natural and delicate.

[0031] The nasal prosthesis in the above embodiments is a one-piece component made of expanded polytetrafluoroethylene (ePTFE) and CNC-carved.

[0032] Specifically, expanded polytetrafluoroethylene (ePTFE) material has good biocompatibility, is less likely to cause rejection reactions, and has stable and long-lasting postoperative effects. It is sculpted using a CNC engraving machine, resulting in a more precise fishtail and hump shape, which can better present the effect and avoid the errors of manual engraving. At the same time, using pre-molded fishtail and hump ePTFE can shorten the doctor's engraving time and reduce the exposure time to air, thereby reducing the infection rate. It can also provide more options and convenience for novice doctors with less experience, and shorten the operation time.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
