Embodiment 1

[0031] This embodiment provides a nasal prosthesis, such as figure 1 As shown in -3, it includes the dorsum part 10, the tip part 20 and the columella part 30, the dorsum part 10 is connected with the columella part 30 through the tip part 20 as a whole.

[0032] The inner surface 10a of the nasal dorsal portion 10 is recessed inwardly based on the outer surface 10b of the nasal dorsal portion 10 to form a pit 11 , wherein a support portion 40 is provided in the pit 11 .

[0033] Specifically, the back of the nose part 10 is formed into an arc shape with uniform thickness or close to uniformity, and achieves a uniform transition. The distance between the inner side 10a and the outer side 10b of the back of the nose 10 is not more than 5mm, such as 3mm, where the nose The distance between the inner side 10a and the outer side 10b of the back portion 10 does not include the thickness of the support portion 40 in the recess 11, and mainly refers to the thickness of the thin arc f...

Embodiment 2

[0040] This embodiment provides a nasal prosthesis, such as Figure 4 As shown in -5, on the basis of Embodiment 1, the dorsal part of the nose 10 is provided with a through hole 13 passing through the inner surface 10a and the outer surface 10b for tissue growth to form a stable structure.

[0041] Correspondingly, a through hole 13 may also be provided on the nose tip portion 20 .

[0042] Everything not involved above is applicable to the prior art.

Abstract

The invention provides a nose prosthesis which comprises a nose back part, the inner side face of the nose back part is sunken inwards with the outer side face of the nose back part as the reference to form a pit, and a supporting part is arranged in the pit. The overall thickness of the nose back part is small, the adaptability is high, and after the product is taken out, new tissue can enable the nose to still have a certain height.

Description

technical field [0001] The invention relates to a nasal prosthesis, in particular to a nasal prosthesis which can make the nose still have a certain height after the new tissue is taken out. Background technique [0002] Nasal prosthesis implantation refers to the operation of improving the appearance of the nose by filling the nose with autologous, allogeneic tissue or tissue substitutes to elevate the external nose. Nasal implants are commonly used cosmetic materials. Existing nasal implants are generally made of solid silicone rubber, polytetrafluoroethylene and other materials. [0003] In the prior art, Chinese patent 01258164.X discloses a nasal implant implanted in the nose, 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 the nasal prosthesis includes the bridge of the nose, the tip of the nose and the columella, and several ...
