1. PPDO thread carving lift mainly solves the problem of morphological aging

Facial aging is due to the passage of time and the action of gravity, which causes the fibers and ligaments that support the skin and soft tissues to relax, causing the skin, fat, and muscles to be sagging and sagging due to the influence of gravity, the most important being the SMAS fascia system and the eye and zygomatic fat pads. The sagging and sagging of the cheek structure, the deepening of the nasolabial fold, the loss of fullness of the cheeks and the appearance of wrinkles, and the sagging of the facial skin. Therefore, lifting and repositioning the sagging full-zygomatic fat pad has become the key to modern facial lifting.

2. PPDO line carving

concept

Thread carving is a medical thread that can be dissolved and absorbed by the human body. It is injected into the skin below the dermis layer, and the tension of the skin is created in the desired direction. It has almost no side effects. It replaces the traditional face lift and is a new type of safety. , Effective and minimally invasive facial wrinkle removal method.

By implanting a special thread, it not only has a direct lifting effect, but also improves the quality of the skin at the same time and restores the skin to a youthful state. Facial line carving not only has the effect of lifting the face, but also promotes the regeneration of collagen in the dermis layer of the skin through fibrosis in the dermis, creating a natural facial line for you. Furthermore, collagen can increase the elasticity of the skin, increase the brightness of the skin, shrink pores, and whiten the skin. Protein line face lift surgery only requires epidermal anesthesia for 10-20 minutes before injection. There are no side effects and no scars after surgery. It is also suitable for sensitive skin. It will bring miraculous rejuvenation after 3-5 months. Effect. There is no recovery time for Thread Sculpting face lift surgery, and you can live and work normally after the injection.

PPDO thread carving: It is one of the thread carving techniques. It refers to the subcutaneous implantation of medical absorbable sutures made of PPDO (polydioxanone) material to lift muscles, tighten skin, and stimulate collagen. Regeneration, to achieve the purpose of suspension lifting, an anti-aging technology, is the best line carving technology among many line carving methods.

PPDO thread carving is to use a special guide needle to pour polymer chemical synthetic materials into the soft tissues of all levels of the body surface, and use its good lifting effect and mechanical average distribution to reset, tighten, and lift the slack facial tissue. Correct sagging soft tissue, and promote collagen formation, and finally absorb all passively to form a new supporting ligament. However, its tension will not change, achieving multiple functions such as preventing aging, removing wrinkles, correcting sagging, and smoothing wrinkles and depressions. Because of the passive absorption of linear materials, collagen in the body replaces the supporting ligaments generated, so the face is lifted and firmed. The effect can last longer without foreign bodies remaining in the body

Absorbable suture development background

The first generation of absorbable sutures: catgut, characterized by low strength, rough silk surface, and poor biocompatibility;

Second-generation absorbable sutures: PGA/PGLA braided sutures improve the strength of the first-generation absorbable sutures and have better biocompatibility, but bacteria are easy to inhabit;

The third generation of absorbable sutures: PDS (PDO, p-dioxanone) monofilament sutures. Smooth silk surface is good for operation, not good for bacteria to live in, high tensile strength and better biocompatibility;

The latest generation of absorbable sutures: PPDO (polydioxanone) monofilament suture, PPDO is a polymer of PDO, with better biocompatibility, absorption period of 180 days, and higher resistance Tensile strength, better knot holding performance, and safer and more reliable clinical use.

Production and Sterilization Times

1. From spinning and setting, to 3D printing into 360-degree bidirectional barbs and needles, it takes 30 days for each batch

2, ethylene oxide sterilization takes 14 days

3. After sterilization, the ethylene oxide analysis time is 21 days

4. It takes 35 days for the drug test report to come out

Structure and Properties of Polydioxanone PPDO

1. Flexibility

PPDO is an aliphatic polyester with good flexibility due to its unique ether bond in its molecular chain.

2. Degradability

The degradation of PPDO is mainly caused by hydrolysis. Water will lead to the breakage of low molecular chains. In vivo, these chain segments can be metabolized and absorbed by the body or bioabsorbed. Most of the degradation products are excreted from the respiratory tract, and a small amount from the urethra and feces. discharged in. Specific degradation process: polydioxanone - glyoxylic acid - oxalic acid - urinary glycine - serine - pyruvate - acetyl coenzyme - carbon dioxide and water.

Physical and chemical properties of PPDO wire

Polydioxanone is a polyester polymer, which is characterized by being afraid of water and oxygen.

1. Afraid of water, the inner packaging of the wire is made of breathable paper to ensure that water molecules will not enter.

2. Afraid of oxygen, the outer packaging is packed with aluminum foil, and the filling gas is ammonia gas, which protects the polydioxanone, and at the same time isolates the air, that is, it mainly isolates oxygen.

Polydioxanone has good physical and mechanical strength, chemical stability, bio-histocompatibility, and safety, and is biodegradable. It is completely decomposed into carbon dioxide and water in the body, with metabolism and microcirculation. Excreted without any residue, it is the latest generation absorbable suture material.

Biological properties of PPDO threads

1. The diameter of No. 0 thread is 0.5mm, which is mainly used in full face lift, and the absorption period is more than 180 days; the diameter of No. 1 rhinoplasty thread is 0.6mm, the absorption period is longer, and the body fluid on the face is relatively less. , so the absorption time of the line is also extended.

The process of absorption

1. Invisible degradation period: 8-12 weeks before the PPDO thread is implanted under the skin, the degradation is slow, there is no obvious decomposition, and the inflammatory reaction is mild

2. Dominant degradation period: After 8-12 weeks, the degradation begins to accelerate and is gradually destroyed into fragments, which are foreign body giant cells, phagocytic cells, plasma cells and other phagocytic tissue reactions are strengthened, showing a mild chronic foreign body reaction, but no Tissue necrosis and obvious granulation tissue hyperplasia appeared, showing good histocompatibility. After 24 weeks, it was finally decomposed into carbon dioxide and water, which was completely excreted without any residue. From this point, it can be seen that the use of PPDO thread is safe.

3. Maintenance time: PPDO thread face lift can be maintained for more than 2-3 years. There is trauma to the needle tract, plus the stimulation of the thread. During the absorption process of the thread, the tissue forms a capsule, the fibrous tissue proliferates, and the artificial tissue of invisible autologous tissue is formed. Ligaments, also known as scarring cords, take 7-8 years to fully absorb the scar tissue in the body. In vitro scar tissue will accompany you for life if you don't take special methods, so there is no problem in maintaining it for more than 2-3 years.

4. PPDO thread is a kind of polymer, with good knot-holding property, smooth and soft thread body, no foreign body sensation after implantation in human body

5. PPDO line is a kind of high molecular polymer, does not contain any protein components, so it will not produce any allergic reaction or produce antigen-antibody reaction

6. The FDA-approved plant extract ingredient Disperse Blue RRL is added to the PPDO line in the production process. This disperse blue RRL has anti-inflammatory, bacteriostatic and hemostatic effects, and in the process of catabolism in the body, decomposes antibacterial products. .

In case of infection. We need to find the reason from the use process to see whether the aseptic operation is guaranteed during the use process. Some people drop the needle and thread on the ground, pick it up and use it directly, which is also the cause of infection.

Features of PPDO line carving

1. Material: safe and reliable. The PPDO (poly-p-dioxanone) used in the suture is completely decomposed into carbon dioxide and water in the human body, without chemical residues, and it is non-toxic and harmless for clinical application. PPDO is a polymer of PDS (PDO to dioxanone), which has better biocompatibility.

2. Independent intellectual property rights, filling the domestic technology gap, and obtaining three national invention patents, leading the world.
