L-shaped nasal stent

Abstract

The invention discloses an L-shaped nasal stent. The L-shaped nasal stent is characterized by comprising a stent body composed of two strip-shaped sheets (1), the length of each strip-shaped sheet (1) is 20-100 mm, the width of each strip-shaped sheet (1) is 0.1-2 mm, a plurality of needle holes (2) are formed in each strip-shaped sheet (1) in the length direction of the corresponding strip-shaped sheet (1), the included angle of the two strip-shaped sheets (1) is 10-90 degrees, the interior angle of the connection of the two strip-shaped sheets (1) is an acute angle, and the outer side edge of the connection of the two strip-shaped sheets (1) is in a circular arc shape. A stable triangular structure can be formed by the L-shaped nasal stent and the nasal septum or the nasal columella or any one plane and tissue, and accordingly reliable fixing and supporting effects are achieved; by means of the uniformly distributed needle holes, a needle conveniently penetrates through the needle holes to seam and fix the tissue, and conditions are provided for coating the stent for the growth and healing of the tissue. The L-shaped nasal stent is novel in design, scientific, reasonable, simple and practical, has a very good in clinical application value and has the advantages of being stable, reliable and convenient to use.

Description

Technical field [0001] The invention relates to the field of medical equipment, and is a new type of medical equipment for rhinoplasty specifically aimed at nose bridge collapse and nose shape correction. Background technique [0002] In rhinoplasty, it is necessary to fix and support the used autologous cartilage or adjusted tissue. Currently in the rhinoplasty industry, the main materials used for rhinoplasty are: autogenous cartilage, solid silica gel, PDS absorbable patch, etc. for prosthetic rhinoplasty; and hyaluronic acid, Aibeifu, expanded polytetrafoethylene (EPTFE) And so on, it is used for injection rhinoplasty. Based on these rhinoplasty materials, there are varying degrees of deficiencies, surgical limitations, and postoperative complications, such as: the arc of the cartilage of the ear concha can easily cause the nasal columella to bend and deform; while the solid silicone material is harmful to human tissues. Cells are irritating to a certain extent and cannot e...

AI Technical Summary

Problems solved by technology

Based on these rhinoplasty materials, there are deficiencies to varying degrees, limited operation, and postoperative complications, such as: the curvature of the cartilage of the concha cartilage can easily lead to bending and deformation of the columella; while the solid silicone material is harmful to human tissues The cells are irritating to a certain extent, and cannot establish good blood circulation and tissue connection with the body, so it is easy to penetrate the skin at the weak tissue (or the skin color of the tip of the nose is abnormal)
