Artificial bionic nose stent

Abstract

The invention discloses an artificial bionic nose stent, which comprises a septal cartilage false body, a lamina dorsi nasi false body, a nasal alar cartilage false body and a nasal alar sesamoid false body connected together, and consists of Medpor, PTFE (Polytetrafluoroethylene) and silica gel. Due to the adoption of the artificial bionic nose stent, a reconstructed nose has the advantages of delicate appearance, satisfactory functions and high safety; the material problems of a small quantity of relevant surgical materials for the conventional artificial bionic nose stent and incompatible material performance are solved; and the problems of donor site wounds, donor site complicating diseases and sequelae are solved, and convenience is brought to surgeons and patients simultaneously.

Description

technical field [0001] The invention relates to an artificial bionic nasal support in nasal reconstruction. Background technique [0002] At present, autologous tissue transplantation and artificial material implantation are widely used for cartilage scaffold reconstruction in nasal reconstruction. [0003] The nasal stent formed by autologous tissue transplantation is not only greatly affected by the doctor's sculpting technique, but also often limited by the amount of tissue in the donor area, the inherent shape of the tissue, and the toughness, so that the ideal shape and function of the stent cannot be obtained. After being implanted in the recipient area, the autologous tissue scaffold will be absorbed and deformed to varying degrees, causing the scaffold to be skewed and collapsed. Because in the process of using autologous tissue to reconstruct nasal cartilage scaffolds, each step has corresponding problems, which are briefly summarized as follows: 1. The process is ...

AI Technical Summary

Problems solved by technology

Nasal cartilage scaffold reconstruction using artificial materials has the following disadvantages: 1. The current simple L-shaped, willow-shaped silicone prosthesis, or block PTFE, Medpor prosthesis has a great difference in appearance and function from human nasal cartilage scaffolds. The difference is simply "camouflage" the tall nasal base and nasal dorsum in the reconstructive surgery

As for the greater wing cartilage of the nasal head, there is no prosthesis to reconstruct the shape and function of this structure

Therefore, using existing materials, no matter how superb carving techniques are, it is impossi
