Description

Comprehensive nose shaping support

Technical Field

The utility model relates to an plastic surgery technical field especially relates to a plastic support is synthesized to nose.

Background

The nasal synthetic plastic stent is generally composed of a nasal septum extension graft and a nasal columella support graft, wherein two ends of the nasal synthetic plastic stent are respectively connected with nasal septum cartilage and nasal alar cartilage. The main functions are to prolong the length of the nose bridge and the nose tip, keep the columella nasi, the nasal septum and the nostril in stable neutral or symmetrical positions, and change the shape of the nose tip and the angle of the nose lip. Therefore, the length, height and whether the stent is flat stable are critical to the nasal symplasty.

The comprehensive plastic bracket for the nose is usually made of 3-6 cartilage pieces with higher hardness and more flatness, such as costal cartilage and nasal septum cartilage, in a combination mode of 2+1, 2+2, 4+1 and 4+2 (for example, the structural bracket for the nose plastic disclosed by the patent No. CN 209122538U), or made of one piece of larger costal cartilage (for example, the bracket for the nose head disclosed by the patent No. CN 207136935U), or made of non-human body materials with good biocompatibility, such as bulked body (polytetrafluoroethylene) and silica gel (for example, the comprehensive plastic bracket for the nose disclosed by the patent No. CN 210124876U), and less made of auricular cartilage (auricular cartilage) which is soft and bent.

Costal cartilage is a good comprehensive nasal plastic scaffold material, and has sufficient supply area, excellent supporting force and excellent stability. The width of the costal cartilage is about 10-20mm, the length is about 25-50mm, the thickness is about 5-10mm, and the long and wide surfaces are relatively flat. Disadvantages or limitations: 1. the operation for cutting costal cartilage has larger trauma and risk, sometimes even generates pneumothorax and hemothorax complications and endangers life; 2. the scar part of the chest is not accepted by the operator; 3. is affected by the age and development conditions, and is partially unavailable to patients due to calcification of costal cartilage; 4. sometimes the available costal cartilage is obviously bent, carving and cutting are wasted, and very large cartilage (the length is more than 50mm) needs to be cut to obtain the needed sheet-shaped cartilage, so that the risks of trauma and instability of the chest wall are increased; 6. the facial mask is solid and has insufficient elasticity, the facial mask is stiff, and some people are not satisfied or even need to take out the facial mask.

The nasal septum cartilage is thin and firm, flat and easy to cut. The fabrication of a stent typically requires a nasal septal cartilage that is about 15-20mm wide, about 25-30mm long, and about 1mm thick. Disadvantages or limitations: 1. the available cutting amount is very limited, and moreover, the nasal septum of many patients is short and short in nature, so that enough materials cannot be cut; 2. after cutting the nasal septum cartilage with a larger area, the supporting function and the stability of the nasal septum cartilage are damaged.

Although non-human body materials such as expanded Polytetrafluoroethylene (PTFE) and silica gel are easily available, the long-term safety and effect of the non-human body materials are far lower than those of self-body materials at present, and the non-human body materials are immature technologies.

Auricular cartilage (auricular cartilage) is located on the body surface, no important blood vessels and nerves are arranged around the auricular cartilage, the auricular cartilage is easy and safe to cut, and the auricular cartilage on one side provides 1.5 x 2.5cm area of cartilage without causing obvious changes of functions and forms of the auricle.

However, the use of the ear cartilage is less and less recommended because it has insufficient support stability and prolonged force due to its inherent irregular bending property, and is prone to deflection or retraction deformation in a long term. In addition, the traditional method is formed by cutting the artificial bone into a plurality of small sheet-shaped matrixes (4 to 6 sheets) and splicing the small sheet-shaped matrixes, and the operation is complex and time-consuming.

SUMMERY OF THE UTILITY MODEL

Based on this, the utility model provides a plastic support is synthesized to ear cartilage nose that more firm and easy operation.

The utility model provides a technical scheme that its technical problem adopted is: one end of the nasal comprehensive plastic bracket is fixedly connected with nasal septum cartilage (4), and the other end of the nasal comprehensive plastic bracket is fixedly connected with the inner side feet (5) of nasal alar cartilage and a fornix (6), and the nasal comprehensive plastic bracket mainly has the functions of increasing the length of the bridge of the nose and the height of the nasal tip, keeping the columella nasi and the nostrils in stable neutral or symmetrical positions, and adjusting the shape of the nasal tip and the angle of the nasal lip. The method is characterized in that: the ear cartilage is formed by oppositely suturing, cutting and reforming two ear cartilage depressed surfaces which are approximately symmetrical and bent depressed, and has special shape and function subareas; after the ear-shaped cartilage is relatively sewed and before the ear-shaped cartilage is cut and reshaped, the two pieces of bent ear-shaped cartilage are combined together and have a shape similar to a shell; after cutting and reshaping, the shape of the artificial bone is a relatively straight plane, and a definite head part (1) and tail parts (2 and 3) are formed, wherein the tail parts are like dovetails.

Detailed Description

1. Cutting ear cartilage in bilateral symmetry region, wherein the width is about 15mm, and the length is about 25 mm; the auricular cartilage is preferably obtained from bilateral concha boats (9) and comprises a crural transition zone (10) and, if necessary, a antihelix transition zone (11); and secondly from the concha cavity.

2. The two ear cartilage bones are opposite inwards according to the concave surfaces of the symmetrical points, and 2-4 needles are sewn and fixed at the edges to prevent displacement.

3. The tail end of the tail part is split into swallow tail shapes (2, 3) by cutting along the long shaft part of the depressed face, and meanwhile, the depressed face of the cartilage is flattened to form a flat head part (supporting part) and a flat tail part (clamping part).

3. The tails (2, 3) are respectively clamped at the front and rear corners of the tail side of the nasal septum cartilage (4) and are sewn and fixed to form a middle supporting plane.

5. The three planes are connected in a common edge manner to form a firm support which is similar to the firm support formed by connecting two hinges in a superposed manner.

6. The length of the nose bridge and the columella nasi is further finely adjusted by cutting and overlapping small pieces of cartilage and fascia on the head part (1) of the bracket, and the shape of the nose tip and the angle of the nose lip are adjusted.
