Description

Technical Field

[0001] The present invention belongs to the technical field of plastic surgery, and in particular relates to a device and method for lifting skin tissue for sagging skin. Background Art

[0002] As people age, wrinkles form on the surface of their face or body. Wrinkles form because muscles contract and the skin and fat layers sag due to gravity. Wrinkles form perpendicular to the direction of muscle contraction and deepen with age.

[0003] Precise rejuvenation of the aging face depends not only on a correct preoperative analysis of each patient's deformity, but also on the correct choice of technique to adequately address each of the relevant anatomical factors. Currently, a variety of surgical approaches have been established in the field of facial cosmetic surgery, each addressing specific problems. For example, chemical peels, Botox, TM and filler injections to improve the structure of the skin. Minimally invasive surgery and other surgical procedures such as face lifts including forehead-forehead lifts, midface lifts, and neck lifts can address excess skin.

[0004] The main lifting methods used in existing surgical operations are:

[0005] 1) Use nylon thread or polymer synthetic thread with barbs, insert it under the skin and pull it upward to lift the skin;

[0006] This type of barbed nylon thread or polymer synthetic thread is made by cutting an incision on the thread with a knife. It is easy to break at the incision during use. The thread is also not elastic and soft, and is not suitable for areas with high skin mobility. The lifting effect lasts only a few months, and there are also problems such as easy exposure and many complications.

[0007] 2) A toothed silicone rubber elastic cord or sheet is inserted under the skin and pulled upward to lift the skin;

[0008] This method has a pulling effect at the edge of the flat line, which is easy to slip off.

[0009] 3) Sutures, which sew the sagging tissue upward to lift it up;

[0010] Since sutures have a strong cutting effect on soft tissue, the lifting effect is shorter and often disappears within a few months.

[0011] The lifting methods in the prior art are all one-time effects, and the lifting strength cannot be adjusted as the age increases, that is, secondary adjustment is not possible. Summary of the invention
