Description

Lifting thread for rhinoplasty and manufacturing method thereof

The present invention relates to a lifting thread, and more particularly, to a lifting thread used for nose shaping.

The representative symptoms of skin aging are skin sagging and the occurrence of wrinkles. As a method to improve this, the medium face lift pulls the skin in one direction, excises excess skin, and then sutures it, but there is a risk of scarring and side effects as a surgical treatment.

Deviating from the surgical method, a suture that is harmless to the human body that can mechanically pull the skin is inserted into the skin to induce a natural immune response in the human body, thereby causing collagen synthesis, angiogenesis, and lipolysis. A lifting procedure has been developed that promotes the regeneration of the skin and uses the tension of the lifting thread to lift and fix the sagging skin tissue.

Among these procedures, in particular, in the procedure for correcting a fallen nose tip, a curved nose, or a low nose bridge using a lifting thread for rhinoplasty, both ends of the lifting thread are inserted into the subcutaneous layer of the nose so that the lifting thread supports the nose in a constant shape. It can create volume or raise the bridge of the nose, and at this time, a lifting thread is separately placed on the bridge of the nose and the nasal bridge.

In this way, when the lifting thread is inserted into the nose to support the shape of the nose, the nose tries to return to its original shape, so it continuously receives tension over time. It often happens that one end of the thread irritates the skin, resulting in inflammation or protrusion through the skin. In this case, the lifting thread must eventually be removed, and problems such as tissue damage occur in the process. In addition, there is a limitation in that the effect on the tip of the nose is lowered because the nose treatment so far only supports the bridge of the nose and the nasal bridge, but does not support the tip of the nose.

Therefore, there is an urgent need to develop a lifting thread for rhinoplasty that improves the conventional limitations in a form that prevents external protrusion or inflammation during rhinoplasty and supports the tip of the nose, unlike the conventional lifting thread.

1 is a view showing a method of manufacturing a lifting seal for nose shaping according to an embodiment of the present invention.

Referring to FIG. 1 , the manufacturing method ( S10 ) of the lifting seal for nose molding may include an injection step ( S11 ) and a pressing step ( S12 ). In the injection step ( S11 ), a lifting seal including the first area and the second area may be injected. The lifting thread is a thread made for the purpose of a surgical procedure, in particular, a thread made for a lifting procedure to raise the bridge of the nose or the angle of the tip of the nose for rhinoplasty, and may be called by other names such as lifting thread.

The first area and the second area of the lifting thread may be determined according to a position to be inserted during a lifting procedure. In one example, the first region of the lifting thread may correspond to the bridge of the nose positioned at the upper part of the nose, and the second region of the lifting thread may correspond to the nasal bridge positioned at the lower part of the nose. The first region and the second region may be manufactured in different shapes, which will be described later in detail with reference to FIG. 2 .

In one embodiment, the injection step (S11) of the lifting thread may inject the lifting thread by injecting the raw material into the mold in which the first region and the second region are provided, and in one example, the raw material is polydioxanone (polydioxanone) ), polylactic acid, polyglycolic acid, polycaprolactone, and at least one of copolymers thereof, but this is only an example and the technical spirit of the present invention is limited thereto doesn't happen The lifting yarn injected by the raw material may have an overall elastic property. In one embodiment, when the raw material is inserted into the human body, it is absorbent and can be absorbed into the skin tissue over time and disappear, thus reducing the burden of the operation of the recipient with a non-permanent material.

In another embodiment, the lifting seal may be constructed of a temperature restoring material (eg, a shape memory alloy). In the above embodiment, the lifting thread may be formed to have a predetermined angle at body temperature, and an angle set appropriately for the person to be treated may be stored in the lifting thread, and as the lifting thread restores the predetermined angle inside the body, the lifting thread is lifted. The procedure can be performed efficiently.

A connection region may be formed at a portion where the first region and the second region of the lifting seal are connected. In the pressing step (S12), the connection region may be formed by pressing between the first region and the second region of the lifting seal in a bent state at a predetermined angle. In an embodiment, the predetermined angle may have any value in the range of 60 degrees to 150 degrees. In an embodiment, the pressing step S12 may be performed at a predetermined temperature, and in one example, the predetermined temperature may have any value between 40 and 60 degrees Celsius.

According to the technical idea of the present invention, the lifting thread may be formed to correspond to the shape of the nose by forming the connection area at a predetermined angle. When performing a lifting procedure on the nose using the lifting thread formed according to the present invention, the procedure can be performed using a lifting thread of a shape suitable for the angle of the patient's nose tip, and the force to maintain the predetermined angle Since this is generated and does not penetrate into the internal tissue, damage to the internal tissue can be minimized even if the lifting thread is placed for a long time.

In addition, in the prior art, by performing a lifting procedure using two lifting threads, the length of the nose bridge and the length of the nasal bridge are different for each patient, so in some cases, the lifting thread remains, and in other cases, the lifting thread is insufficient. , the lifting thread continuously stimulates the epidermis of the recipient's nose, causing inflammation, protrusion, or failure to apply force at the correct location, resulting in problems with the recipient's body.

On the other hand, if the lifting thread formed according to the present invention is used, a lifting procedure can be performed using one lifting thread connecting the bridge of the nose and the nasal passages, and as the connection region between the first region and the second region is located at the tip of the nose As the problem of stimulating the epidermis at the tip of the nose is reduced, and the connection area is formed to be seated at the tip of the nose, it is not necessary to cut the lifting thread according to the person to be treated at the procedure site, so the convenience of the procedure can be greatly increased.
