Problems solved by technology

[0005] In the clinical application of rhinoplasty, due to the smooth surface of the nasal prosthesis made of silicone rubber, the tissue cannot be better combined with the prosthesis after implantation, and there will be problems such as prosthesis displacement and light transmission, which will lead to the treatment of nasal prosthesis. The effect becomes worse

Embodiment Construction

[0024] A method for manufacturing a composite nose bridge prosthesis with surface micropores, comprising the following steps:

[0025] Step 1: Sand blast the mold surface of the silicone rubber nose bridge prosthesis to form a certain roughness of 1-3 μm;

[0026] Step 2: Put the silicone rubber into the mold cavity for vulcanization, take out the product after vulcanization, and trim the excess residual edges to make a silicone rubber nose bridge prosthesis with a certain roughness on the surface of the back of the nose, with a roughness of 1-3 μm ;

[0027] Step 3: Cut the expanded polytetrafluoroethylene strip with scissors according to the size and shape of the nasal dorsal surface of the silicone rubber nose bridge prosthesis;

[0028] Step 4: Dissolve medical semi-solid silicone rubber in petroleum ether solvent to fully dissolve it;

[0029] Step 5: Apply the liquid silicone rubber with a certain viscosity prepared in step 4 evenly on the upper surface of the lower pr...

Abstract

The invention discloses a fabrication method of a composite nasal bridge prosthesis with surface micropores. The method comprises the following steps: step 1: sandblasting the mold surface of siliconerubber nasal bridge prosthesis to form a certain roughness of 1-3 [mu]m; step 2: putting the silicone rubber into a mold cavity for vulcanization, taking out the product after vulcanization, trimmingthe excess residual edges, making a silicone rubber nasal bridge prosthesis with a certain roughness on the surface of the nasal back, and the roughness being 1-3 [mu]m; and step 3: cutting the expanded polytetrafluoroethylene strip with scissors according to the size and shape of the back surface of the silicone rubber nasal bridge prosthesis. The beneficial effect is that the composite nasal bridge prosthesis with surface micropores prepared by the present invention can allow tissue cells to grow in, the defects of postoperative prosthesis displacement caused by the smooth surface of silicagel, light transmission, etc., are effectively solved, and the therapeutic effect of the nasal bridge prosthesis is improved.

Description

technical field [0001] The invention relates to the field of making a composite nose bridge prosthesis, in particular to a method for making a composite nose bridge prosthesis with surface micropores. 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 environmental conditions. High aging resistance, excellent bioc...
