Description

Lifting member for molding {LIFTING DEVICE FOR PLASTIC SURGERY}

The present invention relates to a lifting member for cosmetic surgery, and more particularly, to a cosmetic lifting member capable of reducing the occurrence of scars.

Recently, plastic surgery to look young has been prevalent according to the trend of putting importance on the appearance of men and women of all ages. As a simple procedure to look younger, there is a procedure to remove or straighten wrinkles on the skin.

The surgical method for removing wrinkles includes an incision method in which a large incision is made in the skin and then sagging tissue is removed, and a minimal incision method in which a large incision is not required and wrinkles are removed simply by hanging a protrusion or barb-shaped thread on the affected area and lifting it. There is Minimally Invasive Surgery, and recently, the “minimally invasive” surgical method that enables “quick” recovery and “daily life” is preferred in the “plastic surgery market”.

In detail, the minimally invasive surgical method uses absorbable threads instead of incising the skin to lift up the aged skin on the outside and the aged soft tissue and superficial musculo-aponeurotic system (SMAS) in the skin together. It is a surgical method that removes wrinkles and restores tightness.

This is a disadvantage of the scalpel surgery method by using a needle through simple local anesthesia, and scarring can be reduced. It is widely used because it not only reduces irritation or damage to the operated area, but also reduces bleeding or swelling caused by surgery, giving natural tension after surgery to make the skin look elastic and youthful. Depending on the symptoms of skin sagging, the thickness of the needle and thread increases proportionally.

On the other hand, in the case of 18G (diameter 1.28mm), which is most often used for thread lifting, a cannula with a blunt end is used. At this time, the operator typically uses a cannula with a blunt end and inserts it deeply into the patient's skin.

In this regard, Republic of Korea Patent Registration No. 10-1472943 (published on December 16, 2014) is formed in a cylindrical shape with both ends opened in the longitudinal direction, and a hollow part is formed, embedded in the skin layer for skin wrinkles, and formed on the outer surface. In the cannula for skin wrinkle shaping including a needle in which a chamber in which a barbed portion is formed is inserted through the hollow portion, the needle has a guide jaw formed by stainless welding from an end inserted into the skin layer, and the guide jaw is formed. A cannula for shaping skin wrinkles is known, characterized in that the top is opened 2.0 mm to 5.0 mm from the formed end in the longitudinal direction of the rear end of the needle to form an opening through which a chamber passes.

However, when the cannula with a blunt end is inserted into the skin as in the prior art, there is a problem that a wound may be created on the skin and scarring may occur on the face.
