Embodiment 1

[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0037] In this embodiment 1, both the wire body 1 and the damping cone 2 are made of zinc alloy wire material. Using ICP-AES to analyze the alloy composition of the zinc alloy wire material, the measured magnesium content is 0.5%, the content of impurity elements is not more than 0.01%, and the rest are all zinc elements. Of course, it can also be zinc-calcium alloy, zinc-magnesium-calcium alloy, zinc-lithium alloy, zinc-strontium alloy, zinc-calcium-strontium alloy, zinc-magnesium-lithium alloy, zinc-manganese alloy, zinc-magnesium-manganese alloy, zinc Any one of a magnesium-copper alloy, a zinc-neodymium alloy, a zinc-yttrium alloy, and a zinc-gadolinium alloy. In this embodiment, the zinc alloy is a zinc-magnesium alloy. After testing, the tensile strength of the material extruded bar is 320MPa, the yield strength is 280MPa, the elongatio...

Embodiment 2

[0047] In Example 2, the material is made of magnesium alloy. Specifically, it is a magnesium-zinc-calcium microalloy material. Using ICP-AES to analyze the alloy composition of the magnesium alloy material, the measured zinc content is 2%, calcium content is 0.5%, impurity element content is not more than 0.01%, and the rest are all magnesium elements . The mechanical properties of the material in the extruded rod state are tensile strength of 200MPa, yield strength of 160MPa, elongation of 22%, and reduction of area of ​​28%.

[0048] In Example 2, the biodegradable beauty lifting wire is made of magnesium alloy wire material, and its processing method is the same as that of the wire material in Example 1. Vacuum smelting, hot extrusion molding, spinning The compound processing method of forging, cold drawing and wire drawing, in which the raw materials are vacuum smelted with a purity higher than 99.99%. The diameter of the obtained magnesium alloy wire is 0.5mm. Accordin...

Abstract

The invention discloses a biodegradable beauty lifting string and a preparation method thereof. The biodegradable beauty lifting string is made of a degradable metal and comprises a string body and aplurality of damping cones distributed on the string body, the damping cones are made of the string body through weaving and winding, the damping cones are of heart shapes, and the cusps of the damping cones face toward the same direction. The cone bottom diameters of the damping cones are between 0.2 and 5 mm, and the cone heights are between 0.3 and 6 mm. According to the biodegradable beauty lifting string and the preparation method thereof, the lifting string can be safely degraded in the human body without the need of being taken out by a secondary surgery, and the problems that clinically, the existing lifting string prepared with polylactic acid-based polymer material is fast in degradation and short in treatment period are solved.

Description

technical field [0001] The invention relates to the field of medical beauty devices, in particular to a biodegradable beauty lifting thread and a preparation method thereof. Background technique [0002] At present, the commonly used facial plastic lines in plastic surgery include zigzag lines and silicone elastic lines, but the postoperative lifting effect has been unsatisfactory. The teeth of the zigzag line for facial plastic surgery are small and soft, and the lifting force of the skin is not enough in the actual use process, and it is easy to slip off after the operation. The silicone elastic thread feels tight after entering the human tissue at the beginning. After a long time, the elasticity disappears and returns to its original shape. The long-term lifting effect cannot be achieved, which leads to the failure of the operation. The above two products are cylindrical, and after the formation of connective tissue hyperplasia, the whole slips off and cannot be fixed on...
