Background

Cosmetic treatment of the nasal organs of the human body usually requires the use of a nasal prosthesis. Generally, a nasal prosthesis comprises a three-part structure of the dorsum of the nose, the tip of the nose and the columella nasi. Through cosmetic surgery, the nose prosthesis is arranged between muscle tissues and skin tissues of the back of the nose, the tip of the nose and the columella nasi of a patient, and the appearance of the nose of the patient is shaped through the nose prosthesis, so that the cosmetic effect of changing the shape of the nose is achieved.

The nose prosthesis commonly used in the market at present is divided into a plurality of models according to the length and the size of the nose of a human body for mass production, and the external shapes and the sizes of nose prosthesis material pieces of the same model are the same.

Because of individual difference of the plastic, when the existing nose prosthesis is used for the plastic, the situation of overlong or overlong exists always, an operator needs to manually cut and correct the length piece of the nose prosthesis according to the size of the nose of the operator, because the nose prosthesis is generated by pressing into a whole, the cutting size can only be corrected from the upper end of the back of the nose, the nose prosthesis is influenced by factors such as the technical level, the operation experience and the like of the cosmetic operator, the manually corrected nose prosthesis at the upper end of the back of the nose has overall shape change, the fitting of the cosmetic nose prosthesis and the nose tissue is influenced, and the operation quality is difficult to guarantee. Especially, when the nose prosthesis is too short, the nose prosthesis cannot be corrected, and the nose looks straight and stiff when being observed from the side after reshaping, so that the reshaping effect is poor.

In order to solve the problem, a method for engraving and processing the nasal prosthesis by utilizing a laser three-dimensional engraving technology is provided, the method obtains the nasal prosthesis with the shape and the size highly matched with the shape and the size of the nose back of the patient by obtaining the shape and the size data of the nose back of the patient and engraving and processing the material piece of the nasal prosthesis by adopting laser equipment according to the obtained data, the matching degree of the nasal prosthesis and the nose back of the patient is improved, but the price is very high.

The nasal prostheses used in the prior art still suffer from the following drawbacks: the nose tip of the traditional nasal prosthesis is narrower, so that the beak of the nose tip is easy to deform or the prosthesis is deflected, and the nose tip is not full enough and is easy to show; the junction of the nose tip and the nose back of the traditional nasal prosthesis is horizontally connected and is basically at the same height, the nose tip is lower than the nose back due to the large skin tension of the nose tip, a hump nose state is presented, and the leaflet expression points on the nose tip are lost; the bottom surface of the tip of the nose and the columella of the nose of the traditional nasal prosthesis are smoothly connected and are positioned on the same horizontal plane, so that the expression points of the lobule under the tip of the nose are lost.
