Technical Field

[0001] The utility model relates to the technical field of nose bridge jigs, in particular to a segmented spliced ​​expanded body nose bridge jig. Background Art

[0002] During rhinoplasty, a nose bridge prosthesis is needed. The upper and lower sections of the expanded polytetrafluoroethylene nose bridge have the same hardness. When the nose tip moves, the upper section of the prosthesis will move sideways, causing the external nose shape to change. Clinically, many cases of nose bridge deviation and displacement that occur many years after rhinoplasty are related to this. Therefore, a material with three sections of different hardness is designed and bonded to make a nose bridge prosthesis.

[0003] When the three sections of material are cured and spliced, there is no good positioning fixture, which causes the splicing to be skewed and the defective rate to increase. In addition, when splicing, the connection positions need to be cured. If the connection positions are not fully cured, it is easy for splicing marks to remain and the splicing to be incomplete.
