Embodiment Construction

[0024] A method for making a composite nose bridge prosthesis, comprising the following steps

[0025] Step 1: Sandblasting the surface of the mold cavity of a silicone rubber nose bridge prosthesis with grooves on the nose strap, so that the surface of the mold cavity has a certain roughness of 1-3 μm;

[0026] Step 2: Put the silicone rubber into the mold cavity in step 1 for vulcanization to make a prosthesis with a groove in the middle of the silicone rubber nose bridge. The surface roughness of the product is 1-3 μm;

[0027] Step 3: Cut the expanded polytetrafluoroethylene plate into pieces equal to the groove depth and shape of the silicone rubber prosthesis;

[0028] Step 4: Dissolve medical semi-solid silicone rubber in petroleum ether solvent to make it fully dissolved, and the viscosity is 700-800cP at room temperature;

[0029] Step 5: Apply the silicone rubber liquid with a certain viscosity prepared in step 4 evenly on the nasal dorsum groove of the silicone rub...

Abstract

The invention discloses a composite nose bridge prosthesis manufacturing method. The composite nose bridge prosthesis manufacturing method comprises the following steps of step 1, performing sand blasting treatment on the surface of a mold cavity of a silicone rubber nose bridge prosthesis with a nose strap groove to form a certain roughness of 1-3 [mu] m on the surface of the mold cavity, and step 2, performing vulcanizing on silicone rubber in the mold cavity of the mold in the step 1 to obtain the silicone rubber nose bridge prosthesis with the groove in the middle, wherein the roughness ofthe surface of the product is 1-3 [mu] m, and 3, cutting the expanded polytetrafluoroethylene plate into blocks with the same depth, shape and size as the groove of the silicone rubber prosthesis. The composite nose bridge prosthesis has the beneficial effects that the prepared composite nose bridge prosthesis has certain supporting strength, the defects of displacement, light transmission and the like cannot be generated after an operation, tissue cells can enter the composite nose bridge prosthesis after the composite nose bridge prosthesis is used, the composite nose bridge prosthesis canbe tightly attached to the tissue cells, and the using effect of the composite nose bridge prosthesis is improved.

Description

technical field [0001] The invention relates to the technical field of manufacturing nasal bridge prosthesis by compounding expanded polytetrafluoroethylene and silica gel, in particular to a method for manufacturing a composite nasal bridge prosthesis. Background technique [0002] Polytetrafluoroethylene is a polymer compound containing fluorine atoms in the main chain of the molecule. The F atoms in the PTFE molecule cover the C-C bond and the C-F bond has high bond energy and good chemical stability; since it came out in the 1960s , PTFE is widely used in industrial, medical, military and other fields because of its stable physical and chemical properties and good biocompatibility. [0003] Silicone rubber is a linear high-molecular-weight polyorganosiloxane whose main chain is composed of silicon and oxygen atoms alternately. Its unique chemical structure determines its good physiological inertness and body fluid corrosion resistance. It can be used in harsh environment...
