Embodiment 1

[0040] Such as image 3As shown, the nasal prosthesis 1 includes the bridge of the nose 2, the tip of the nose 3, and the columella 4. The bridge of the nose 2 is connected to the columella 4 through the tip of the nose 3. The bridge of the nose 2 includes a surface layer 6 for shaping and a fitting layer for fitting with the nose 5. The bonding layer 5 and the surface layer 6 are made of the same material. The surface layer 6 of the bridge of the nose 2 has no holes, and the bonding layer 5 has many holes 7. The bonding layer 5, which is made of the same material as the surface layer 6, becomes soft. Yes, and it is elastic, can be stretched, and can fit the nose well. There is a hole 7 that allows body fluids to flow into the hole. 7 is integrated with the nasal prosthesis 1 to prevent it from moving, festering, and postoperative pain for patients. If you want to take out the nasal prosthesis 1, because the nasal prosthesis 1 has elasticity and can be stretched, you can easil...

Embodiment 2

[0042] Such as Figure 4 As shown, the nasal prosthesis 1 includes the bridge of the nose 2, the tip of the nose 3, and the columella 4. The bridge of the nose 2 is connected to the columella 4 through the tip of the nose 3. The bridge of the nose 2 includes a surface layer 6 for shaping and a fitting layer for fitting with the nose 5. The bonding layer 5 and the surface layer 6 are made of the same material, and both the bonding layer 6 and the surface layer 6 of the bridge of the nose 2 have holes 7 of the same density. The surface layer has 6 holes and 7 depths. In this way, the bonding layer 5 is relatively soft, and the surface layer 6 is relatively hard.

[0043] The thickness of the nose bridge 2 of the nasal prosthesis 1 is uneven, so the depth setting of the hole 7 needs special treatment. We divide the thickness of the nose bridge 2 into preset layers, such as 10 layers, 20 layers, etc., so that the thickness of each part of the nose bridge 2 is different, and the l...

Embodiment 3

[0045] Such as Figure 5 As shown, the nasal prosthesis 1 includes the bridge of the nose 2, the tip of the nose 3, and the columella 4. The bridge of the nose 2 is connected to the columella 4 through the tip of the nose 3. The bridge of the nose 2 includes a surface layer 6 for shaping and a fitting layer for fitting with the nose 5. The fitting layer 5 and the surface layer 6 are made of the same material, the density of the holes 7 of the fitting layer 5 is greater than the density of the holes 7 of the surface layer 6, and in the area of ​​the same thickness layer of the nasal prosthesis, the fitting layer 5 and the surface layer The skin 6 has holes 7 of the same depth.

[0046] The surface layer 6 has a hole 7 to allow body fluids to flow into the hole 7 and integrate with the nasal prosthesis to enhance its fixity and prevent the nasal prosthesis from moving. The surface layer 6 is harder than the bonding layer 5 and can play a better shaping effect.

Abstract

The invention discloses a nasal prosthesis. The nasal prosthesis comprises a nasal tip, a nasal columella and a noise bridge, wherein the nose bridge is connected with the nasal columella through the nasal tip, the nose bridge comprises a surface layer used for finalizing the shape and an attaching layer used for being attached to the nose, and the hardness of the attaching layer is smaller than that of the surface layer. According to the nasal prosthesis, because the hardness of the attaching layer is smaller than that of the surface layer, after the attaching layer is attached to the nose, the shape can be adjusted more easily according to the contour of the nose, a gap between the nose bridge and the attaching layer is filled in, and even though processing accuracy is low, the attaching layer can be effectively attached to the nose. The nasal prosthesis is simply engraved by a doctor and even can be used without being engraved, much work is saved, efficiency is improved, the requirement for the engraving skill is lowered, and operative difficulty and cost can be reduced easily. The surface layer of the nasal prosthesis is made of hard materials and can be used for being well shaped, and it is guaranteed that the nasal type is stable and the nasal prosthesis is not likely to be sunken or unsmooth. Thus, while the attaching degree is improved, the postoperative effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of plastic surgery, and more specifically relates to a nasal prosthesis. Background technique [0002] Rhinoplasty requires the use of nasal prosthesis. Before the operation, the postoperative effect needs to be simulated by computer. Then the doctor chooses the original nasal prosthesis with the most matching shape according to the effect, and compares the expected postoperative effect with a scalpel. The prosthesis undergoes secondary processing, and finally a personalized nasal prosthesis is obtained. Due to the poor precision of manual cutting, there is a large gap between the nasal prosthesis and the bridge of the nose, and the fit is poor, which affects postoperative recovery and even causes the nasal prosthesis to fall off. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a nasal prosthesis and its processing method for improving the fitti...
