Description
Technical Field
The utility model relates to the technical field of medical cosmetology, in particular to a nose shaping prosthesis.
Background
The nasal prongs are lengthened and raised by implanting different types of materials through plastic cosmetic surgery, commonly known as nasal plastic surgery. Is a common operation for eastern asians. The implants currently accepted by most doctors in the industry are "L" nasal prostheses of silicone material and "L" prostheses of polytetrafluoroethylene loft material. Plays a certain beneficial role in improving the nasal morphology. Due to structural defects of the existing prosthesis, the post-operative nose shape is improved only to a limited extent, and postoperative complications can also be caused.
From the principle of physics, the extension of the nose tip (upward lip direction) requires a supporting force from the nose root to soft tissues in the nose tip (actually called a nose ball) outside the bone perichondrium along the nose bone membrane, so that the nose tip is downward to be upward "T", and the elevation of the nose tip requires a supporting force from the nose base to be upward to the nose tip along the interior of the nose columella to be downward "T", which is called as a double "╂" theory of nose shaping in the industry. The nose tip area (the junction of the upper arm and the lower arm of the L-shaped prosthesis) of the nose applied at present is too close to the angle of 90 degrees and is insufficient in width, and the pressure of the tissue unit area in the nose tip area is too high after implantation, which is manifested by too protruding of the nose tip prosthesis, blushing of skin, long-term local skin nutrition disorder, thinning of tissue, even skin bursting and exposure of the prosthesis.
Because the nose tip area of the existing prosthesis is too thick and most doctors are difficult to engrave the nose tip area to the thickness within 2mm by using a surgical knife manually, the implanted prosthesis can lead to the downward pressing of the dome of the nasal vestibule and the crowding compression of the dome space towards two sides, the filtering of air and the uniform dispersion of air flow into the nasal cavity during inspiration are affected, and the following results are caused: 1) Post-operative hyposmia (reduced airflow of odor-containing particles to the top of the nasal cavity); 2) Part of the nasal mucosa is dry and even bleeding; 3) Chronic inflammation of the upper and lower respiratory tract; 4) Is not beneficial to daily cleaning and nursing in the nasal vestibule and nasal cavity; 5) Prolonged nose shaping doctors are more conservative for prolonged elevation of the nose tip with "L" prostheses. Thus, more cumbersome materials have been sought to replace "L" prostheses, such as autologous ear cartilage, costal cartilage, allograft bone, transnasal cartilage advancement, etc., but with a new set of complications that result therefrom; a skilled nose plastic doctor needs at least 3 hours for performing the costal cartilage plastic operation, and the dissatisfaction rate after operation is high. Popular words: "post-rhinoplasty repair is always on the way".
The upper nasal tip region of most eastern asia people is wider, and the upper nasal tip region of the existing prosthesis is too thick and too wide, so that the original width of the part is increased after implantation, the local blood circulation (local skin redness and even temperature change) is affected, and the activity of the nasal tip is not facilitated.
The length of the upper arm and the lower arm of the existing L-shaped prosthesis is insufficient, and particularly, the short arm is short, so that the expectation of nasal tip elevation during operation of a doctor is limited.

As shown in fig. 1, 2, 3 and 4, the nose tip transition 3 is not a right angle at the interface of the nose bridge 1 and the nose post 2, but a spherical surface having an elliptical surface with a major axis perpendicular to the longitudinal axes of the nose bridge 1 and the nose post 2, the major axis of the ellipse being 12mm and a minor axis being 10mm. The center of the sphere is convex forwards, the supporting force to the nose tip is changed from a relative point to a plane after implantation, the pressure per unit area is reduced, and the spherical bulge does not cause space for compressing the nasal vestibule dome downwards due to the thickness of about 1.3mm and the inherent width of the spherical bulge.
The nose tip of the prosthesis is spherical, and after implantation, a good nose tip shape (spherical, pointed and box-shaped) can be obtained, and the upper edge and the lower edge of the spherical surface are respectively provided with an upper eave 31 and a lower eave 32 which are micro-convex, so that coral bioceramic (CHA) particles or autologous tissues can be placed on the spherical surface to thicken the soft tissues of the nose tip skin. Wherein the upper and lower eaves 31, 32 are perpendicular to the longitudinal axis of the nose bridge 1 and the nose post 2, which in use act as retention.
As shown in fig. 4 and 5, the nose bridge 1 is a hollow column having a rectangular cross section, the bottom end of the nose bridge 1 is connected to the nose tip transition portion 3, and the top end of the nose bridge 1 is smoothly bent outward. The bottom of the nose bridge part 1 is provided with a narrow part 11 corresponding to the upper region of the nose tip, the narrow part 11 is narrow and thin relative to other parts of the nose bridge part 1 (namely, the width and the thickness of the narrow part are smaller than those of other parts of the nose bridge part), the influence on local blood circulation is lightened after implantation, the width of the upper region of the nose tip is not increased, and the touch comfort is more favorable for the mobility of the nose tip. The narrow part 11 is narrower than the nose tip transition part 3, and the narrow part 11 is in smooth transition with the nose bridge part 1 and the nose tip transition part 3.
As shown in fig. 1, 3, 5 and 6, a groove 12 is provided on the back surface of the nose bridge 1, which is attached to the nose bridge bone, and CHA may be placed, so that the gap between the prosthesis and the autologous tissue can be eliminated to reduce the postoperative tissue reaction and the bone erosion effect of the prosthesis on the nose bone (CHA is gradually degraded into own tissue in the tissue). Three round holes 13 are longitudinally formed in the front face of the nose bridge 1 so as to avoid deflection when a doctor engraves the prosthesis. Preferably a circular hole extends through the front face of the nose bridge 1, preferably the face, in the thickness direction, a circular hole 13 extends through the bottom of the recess 12, the circular hole 13 having a diameter of 1.5mm.
As shown in fig. 4 and 7, the cross section of the nose pillar portion 2 is rectangular, the width of the nose pillar portion 2 is smaller than the width of the nose tip transition portion 3, the width of the nose pillar portion 2 and the nose pillar portion are in concave arc-shaped edge smooth transition, and the thickness of the nose pillar portion 2 gradually increases from one end connected with the nose tip transition portion 3 to one end far away from the nose tip transition portion 3.
In use, the implant bed is built along the implantation bed under the nasal bone membrane outside the cartilaginous membrane by about 7mm incision in the nasal flange (1.5-2.0 mm), and the separation range of the lower half of the nose is made according to the requirement, so that the maximum improvement effect is achieved by proper supporting force and proper hardness of the implant.
Because the lengths of the nose bridge part and the nose post part of the prosthesis are long enough, the flexibility that the spherical surface of the transition part of the nose tip is thinner can be realized, and doctors can freely engrave and adjust the prosthesis according to the shaping requirement (such as the extension and heightening of the nose tip, taking the extension as the auxiliary, taking the lifting as the main extension as the auxiliary, and simply lifting the positions of the nose tip and the nose forehead angle). The key parts of the whole nose prosthesis are almost not carved, and other parts are convenient for doctors to carve, so that carving is quick and easy for most doctors, enough space is available for playing, the indication is wider, and the whole comprehensive nose plastic operation can be completed within 1 hour. After implantation, the nose tip area is hemispherical, the prosthesis is not exposed, the nose tip activity is good, and the nose tip has no influence on breath and smell; and the postoperative recovery is fast, the fine tuning is easy, the satisfaction is high, the development of the nose plastic industry is promoted, and the postoperative repair rate is greatly reduced.
