Description

Columella nasi implant

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a columella nasi implant used in plastic cosmetic surgery. The implant can form good retention and fixation at an implanted part, effectively and stably support the nose head and the nose tip, and realize ideal and reliable operation effect.

Background

For the low and flat nose, a nasal columella implant is usually adopted clinically to build a nose support to support the nose. The common method or the implantation of the L-shaped prosthesis material with the columella nasi prosthesis is selected, and the columella part column structure is utilized to support the nose; or autologous cartilages (costal cartilage, nasal septum cartilage and auricular cartilage) are fixed with the front end of the nasal septum cartilage to form a forward and upward extending support to mould the height and the convexity of the nasal head.

However, the columella nasi part of the "L" type prosthesis is easy to move on both sides of the nasal ridge or slide into one side of the nasal ridge after being implanted, and deflection, movement, displacement, abnormal sound and the like occur, which affect the retention of the prosthesis. In addition, the L-shaped prosthesis columella part is often designed into a cylinder or a square column, and the original columella is widened and thickened after being implanted, so that the appearance is influenced. The prosthesis is implanted under the nose skin and poses a potential risk to the long-term safety of the nose skin.

The cartilage of the self cartilage can independently adjust the cartilage support of the nose, so that the shape of the nose is greatly improved. However, the stability of the nasal septum cartilage needs to be fixed on the nasal septum cartilage, the position, the hardness, the nasal ridge shape and the like of the nasal septum cartilage are related, and the constructed bracket can also shift and deflect. In addition, the cartilage is obtained with large wound, and the collection amount is limited by a plurality of self conditions, such as small amount, insufficient calcification, too soft cartilage and the like, which can affect the effect of the operation; additional trauma and risks are also associated with the incision scarring of the material access site, tissue deformation (ear) and other serious complications (rib pneumothorax), and increased surgical complexity.

The top end of the implant can be sutured with the middle feet of the nasal alar cartilages at the two sides, so that the nasal head cartilage support is fixed and shaped again at the new height and the new protruding degree position.

The utility model has the advantages that:

the single columella nasi implant is prefabricated and formed in vitro, materials are not needed to be obtained, the quantity of the materials is sufficient, the implant is manufactured according to the requirement, and the realization of the operation effect is ensured. Unnecessary trauma and complications are reduced, and no complicated operation is required. The strip-shaped medical metal or non-metal material of the implant implantation part is implanted in the nasal ridge bone tissue to form stable retention and fixation, thereby avoiding the phenomena of deflection, movement, displacement, abnormal sound and the like of various nasal columella support materials in the prior art. The columella nasi implant body is in a sheet structure, and the original columella nasi cannot be widened or thickened.
