Abstract

The invention relates to a cosmetic suture thread, which is made of a titanium nickel memory alloy wire. A shape memory function, a superelasticity function and biocompatibility of memory alloy are mainly utilized. The memory shape of the memory alloy wire can be changed under the condition of external temperature, and after the titanium nickel memory alloy cosmetic suture thread is implanted in derma and aponeurosis, the memory shape of the memory alloy wire can be recovered. The derma matches with the aponeurosis in a staggered manner by the aid of mechanical force generated in a recovery process for shape deformation of the memory alloy, the derma shifts in a stacked manner, and a plastic and wrinkle removal cosmetology effect can be achieved.

Description

technical field [0001] The invention relates to a medical cosmetic suture, in particular to a cosmetic suture using titanium-nickel memory alloy wire as a raw material, relying on the good biocompatibility, shape memory function and superelasticity of the memory alloy material to achieve cosmetic surgery Purpose. Background technique [0002] At present, the medical cosmetic sutures used clinically are to use absorbable medical sutures and adopt the aponeurosis suspension operation method to carry out skin-lifting plastic surgery. During the operation process, multiple small incisions are required, which brings a lot of troubles during the operation process, such as: the epidermis must be cut in multiple places, which is easy to leave scars; the suspension force is not easy to control, etc. Contents of the invention [0003] In order to overcome the many inconveniences of the existing aponeurosis suspension operation method for skin-lifting and plastic surgery, the purpos...
