Description

Technical Field

[0001] The invention relates to the technical field of medical cosmetic material components, and in particular to a naturally anti-deflection dolphin-like rhinoplasty prosthesis. Background Art

[0002] With the progress of society and the continuous improvement of people's living standards, medical cosmetology has attracted more and more attention, especially rhinoplasty, which is increasingly favored by those who love beauty.

[0003] Rhinoplasty refers to a procedure that fills the nose with autologous or foreign tissue or tissue substitutes to raise the external nose and improve the appearance of the nose. In the early days of cosmetic plastic surgery, people used paraffin, metal, animal bones and other materials for rhinoplasty. Practice has shown that these materials will cause various adverse reactions after being implanted in the human body, so they have been abolished one after another. Tissue substitutes for cosmetic rhinoplasty are divided into surgical and non-surgical substitutes.

[0004] The most commonly used materials for injectable rhinoplasty nowadays are hyaluronic acid and collagen. Injectable rhinoplasty is quick in effect and minimally invasive, but the bridge of the nose lacks three-dimensionality after the injection, and multiple injections may cause the nose to widen and spread in all directions.

[0005] The tissue substitutes commonly used in surgical rhinoplasty are silicone and expanded polytetrafluoroethylene (e-PTFE). Silicone materials have been used in the human body for nearly a hundred years. The material is stable, resistant to aging, not easy to deform, and cost-effective. However, the disadvantages are light transmission, hardness, shaking, and edge contour.

[0006] In recent years, expanded materials have been favored by doctors and patients because of their good tissue compatibility, softness, and easy shaping. However, at present, there are only two forms of expanded materials produced by manufacturers: one is a processed and carved molding material, and the other is a rectangular block material.

[0007] As patients have increasingly higher requirements for postoperative morphology, pay more and more attention to details, and pursue bionic, natural and realistic postoperative effects, existing molded expanded materials cannot meet customer needs.

[0008] Moreover, if the nasal prosthesis structure is not well designed, the prosthesis and the nasal bridge will not fit well, resulting in local cavities, which increases the risk of infection. Due to the small contact area, the prosthesis is not stable enough and is prone to deflection and displacement, resulting in an unsightly appearance.

[0009] More and more rhinoplasty doctors prefer to use rectangular strips of expanded polytetrafluoroethylene materials to customize a more bionic, realistic and natural nose shape based on the patient's nasal foundation and aesthetic preferences.

[0010] As the requirements of beauty customers become higher and higher, the inverted triangle shape from the brow to the root of the nose, the natural hump of the slightly undulating nasal dorsum, the double C-shaped appearance of the frontal nasal dorsum, and other bionic nasal aesthetic subunits are becoming more and more important. If the nasal prosthesis structure is not well designed, it will lead to an unsatisfactory nasal appearance.

[0011] Moreover, customers are paying more and more attention to the safety of surgery and long-term stability. Traditional prostheses cannot fit perfectly when placed on the nasal dorsum. The ventral side is straight and has no grooves. After implantation, a seesaw-like structural feature is formed, with local cavities, increasing the risk of infection. At the same time, due to the small contact area between the prosthesis and the nasal dorsum, the prosthesis is not stable enough and is prone to deflection and displacement, resulting in an unsightly appearance. Summary of the invention

[0012] In order to make the appearance of expanded polytetrafluoroethylene rhinoplasty materials more natural and bionic and reduce cosmetic failures caused by the shape of the prosthesis, the present invention provides a dolphin-like rhinoplasty prosthesis that is beautiful, natural and bionic and not prone to deflection or displacement.

[0013] In order to achieve the above object, the present invention adopts the following technical solutions: A natural anti-deflection dolphin-like rhinoplasty prosthesis comprises a root portion, a bridge portion and a tip portion made of expanded material, wherein the root portion, the bridge portion and the tip portion form an integrated structure; The root of the nose is in the shape of a dolphin's tail, and includes a brow connecting portion, a forehead connecting portion, and a root of the nose bending portion. The root of the nose gradually becomes narrower and thicker from top to bottom, and the angle of the root of the nose bending portion is a; The nose bridge portion is in the shape of a dolphin's body, and includes an upper side portion, a lower side portion, and a nasal bone vertex bend portion. The nose bridge portion gradually changes from narrow to wide, and from thin to thick from top to bottom; The nose tip portion includes dolphin pectoral fin-shaped extension portions carved on the left and right sides, and the nose tip portion gradually becomes narrower and thinner from top to bottom; The preparation steps of the dolphin-like rhinoplasty prosthesis are as follows: The first step is to select a rectangular expansion block with a length of 7 cm, a width of 1.5 cm, and a height of 0.7 cm, and place it against the user's nose dorsum, with the upper end of the expansion block against the brow bone; Step 2: Press the nasal bone with your fingers to determine the root and tip of the nasal bone, and then use a pen to mark the first and second horizontal marking lines on the upper side of the expansion block. The first and second marking lines correspond to the root and tip of the nasal bone, respectively. Step 2: Mark three vertical third marking lines in the middle of the upper side of the expansion block, and the distance between any two adjacent third marking lines is 0.4 cmcm; In the fourth step, the intersection points of the first marking line, the second marking line, the three third marking lines and the edges of the expansion block include A, B, C, D, a, b, c, d, and A, B, C, D and a, b, c, d are connected in sequence. Finally, the dolphin-like rhinoplasty prosthesis is carved according to the marking lines, among which A, B, a, b areas are the areas to be carved at the root of the nose, B, C, b, c areas are the areas to be carved at the bridge of the nose, and C, D, c, d areas are the areas to be carved at the tip of the nose.

[0019] As a further improvement of the present technical solution: the lower side of the nose bridge is arranged in an arc-shaped concave surface, and the trend of change from the center to the surroundings is in an arc shape.

[0020] As a further improvement of the present technical solution: the lower side of the nose bridge is used to fit on the nasal bone.

[0021] As a further improvement of the present technical solution: the upper side of the nose bridge is arranged in an arc-shaped convex surface, and the changing trend is in an arc shape.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this invention belongs. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0029] As Figure 1-7 shown, a natural anti-deviation dolphin-like rhinoplasty prosthesis provided by the present invention includes a nasal root part 10, a nasal bridge part 20, and a nasal tip part 30 made of expanded polytetrafluoroethylene material. The nasal root part 10, the nasal bridge part 20, and the nasal tip part 30 are of an integral structure. The material of the nasal prosthesis is expanded polytetrafluoroethylene, which has no toxic, carcinogenic, or sensitizing side effects, has good biocompatibility and a unique microporous structure. The diameter of the micropores is 10 - 40 μm (preferably 20 μm). Human tissue cells and blood vessels can grow into the micropores to form tissue connections. It is a very ideal rhinoplasty material. In the initial stage of implantation, the microporous structure on the nasal prosthesis will guide the adsorption of its own tissues, making the nasal prosthesis more fixed and preventing the situation of prosthesis displacement.

[0030] The nasal root part 10 is in the shape of a dolphin's tail. The nasal root part 10 includes a brow connection part 11, a forehead connection part 12, and a nasal root bending part 13. The nasal root part 10 gradually becomes narrower and thicker from top to bottom. The included angle of the nasal root bending part 13 is a, and 120° < a < 150°. A turning plane is designed here. After the prosthesis is implanted, while raising the height of the glabella, the nasofrontal angle is retained, avoiding the appearance of a通天鼻 (a term in Chinese which might need more context to accurately translate, but for now it's left as is), and the appearance is more beautiful. Round chamfers are provided at each end of the nasal root part 10, so that there will be no protrusion at the edge transition during prosthesis implantation, and the human body will be more comfortable. The forehead connection part 12 is a triangular notch facing downwards, which can play an effective role in fixing and preventing skew. The nasal bridge part 20 is in the shape of a dolphin's body. The nasal bridge part 20 includes an upper nasal bridge part 21, a lower nasal bridge part 22, and a nasal bone vertex bending part 23. The nasal bridge part 20 gradually becomes wider and thicker from top to bottom. The nasal tip part 30 includes dolphin pectoral fin-shaped extension parts 31 carved on the left and right sides. The nasal tip part 30 gradually becomes narrower and thinner from top to bottom. The preparation steps of the dolphin-like rhinoplasty prosthesis are as follows: In the first step, a rectangular expansion block 60 with a length of 7 cm, a width of 1.5 cm, and a height of 0.7 cm is selected and placed against the back of the user's nose, with the upper end of the expansion block 60 resting against the brow bone; In the second step, the root and tip of the nose are determined by pressing the nasal bone with fingers, and then a first marking line 40 and a second marking line 50 are marked on the upper side of the expansion block 60 with a pen. The first marking line 40 and the second marking line 50 correspond to the root and tip of the nose, respectively. Step 2: Mark three vertical third marking lines 70 on the middle of the upper side of the expansion block 60, and the distance between two adjacent third marking lines 70 is 0.4 cm; In the fourth step, the intersection points of the first marking line 40, the second marking line 50, the three third marking lines 70 and the edges of the expansion block 60 include A, B, C, D, a, b, c, d, and A, B, C, D and a, b, c, d are connected in sequence. Finally, a dolphin-like rhinoplasty prosthesis is carved according to the marking lines, wherein the A, B, a, b areas are the areas to be carved at the root of the nose 10, the B, C, b, c areas are the areas to be carved at the bridge of the nose 20, and the C, D, c, d areas are the areas to be carved at the tip of the nose 30.

[0031] The upper side portion 21 of the nose bridge is carved into an arc-shaped convex surface, and the change trend is an arc-shaped. When such a prosthesis is implanted at the root of the nose, the nasal bridge presents a naturally undulating slightly hump appearance, and the customer's nose bridge will be more beautiful.

[0032] The lower side part 22 of the nose bridge is carved into an arc-shaped concave surface, which changes from the center to the surrounding in an arc shape, so that the bottom surface of the prosthesis fits better with the bony structure of the nasal dorsum, has stronger stability, is not easy to be skewed, and the human body will be more comfortable.

[0033] The dolphin pectoral fin-shaped extensions 31 on both sides are two triangular appearances, straddling the nose tip 30. When such a prosthesis is implanted at the root of the nose, the two wings increase stability, reduce the pressure on the dorsum of the nose, prevent deflection, and have a natural and beautiful appearance.

[0034] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the technical solution of the present invention.
