Embodiment 1

[0035] Embodiment 1: The manufacturing method steps of bridge of the nose prosthesis of the present invention are as follows:

[0036] a. Compression of the base material of the back of the nose and the base material of the tip of the nose

[0037] (1) Compression of base material on the back of the nose

[0038] Mixed silicone rubber: add 0.4% white by weight to the implantable silicone rubber compound (mixed rubber is the rubber compounded by mixing raw rubber or plasticized rubber according to the formula and the compounding agent through the rubber mixer). The coloring agent is mixed evenly on the rubber mixer, and the mixing time is 15 minutes.

[0039] Compress base material: Divide the mixed rubber according to the weight of the molding material list in Table 1, and perform hot-press molding in four types of molds. Press the mold and check whether it is matched. Adjust the temperature of the flat vulcanizer to be 116° C., and the pressing time to be 8 minutes. After...

Embodiment 2

[0053]a. Compression of the base material of the back of the nose and the base material of the tip of the nose

[0054] (1) Compression of base material on the back of the nose

[0055] Mixing silicone rubber: add 0.3% white coloring agent to the implant grade silicone rubber compound, mix evenly on the rubber mixer, and the mixing time is 15 minutes.

[0056] Press the base material: put the mixed rubber strip in the mold to close the mold, press the mold down with your hands, and check whether it is matched. Adjust the temperature of the flat vulcanizer to be 106° C., and the pressing time to be 8 minutes. After the specified time is reached, the mold is taken out immediately, and trimmed with scissors with a curved arc to obtain the base material of the back of the nose.

[0057] (2) Compression of the base material of the nose tip

[0058] The base material 2 of the tip of the nose is mixed and pressed evenly by adding 0.05% white coloring agent to the implantable liqui...

Embodiment 3

[0068] a. Compression of the base material of the back of the nose and the base material of the tip of the nose

[0069] (1) Compression of base material on the back of the nose

[0070] Mixing silicone rubber: add 0.5% white coloring agent to the implant grade silicone rubber compound, mix evenly on the rubber mixer, and the mixing time is 15 minutes.

[0071] Press the base material: put the mixed rubber strip in the mold to close the mold, press the mold down with your hands, and check whether it is matched. Adjust the temperature of the flat vulcanizer to be 126° C., and the pressing time to be 8 minutes. After the specified time is reached, the mold is immediately taken out, and trimmed with curved scissors to obtain the nasal dorsum base material 1.

[0072] (2) Compression of the base material of the nose tip

[0073] The base material 2 of the tip of the nose is mixed and pressed evenly by adding 0.15% white coloring agent to the implantable liquid silicone rubber, ...

Abstract

The invention discloses a preparation method of a nose bridge prosthesis for plastic surgery, relates to the field of orthopedic medical technology, and aims to solve the problem that the existing silicone rubber nose bridge prosthesis is easy to shift and to be worn after being implanted. The preparation method comprises the following steps: a, pressing a nose back part substrate and a nose tip part substrate; b, surface treating of the nose back part substrate; and c, connecting the nose back part substrate and the nose tip part substrate. The surface treating of the nose back part substrate comprises the following steps: (1), preparation, preparing casting feed liquid; (2), infusion, submerging the nose back part substrate totally into the feed liquid and drying after taking out; (3), sanding, performing sanding operation to the nose back part substrate after submerging; and (4), vulcanization, vulcanizing, cleaning and drying the nose back part substrate after sanding. The invention is especially suitable for manufacturing the nose bridge prosthesis.

Description

technical field [0001] The invention relates to the technical field of plastic surgery, in particular to a method for making a nose bridge prosthesis for plastic surgery. Background technique [0002] Rhinoplasty (plastic surgery) surgery is to change the height and shape of the nose by implanting appropriate materials to harmonize with other parts of the face. It is the most common surgery in the field of plastic surgery. [0003] In medicine, there are many kinds of rhinoplasty materials, such as medical silicone rubber, autologous cartilage, animal tendons or ligaments, puffy (polytetrafluoroethylene), hyaluronic acid, etc. There are also many ways to make nasal bridge prosthesis. Among them, autologous cartilage is self-sourced, so it will not be rejected or sensitized, but it is difficult to shape during the production process. Animal tendons and ligaments are used as raw materials. Because their composition and structure are similar to human tissues, they have good bi...
