preparation example Construction

[0026] Since the preparation methods of magnesium alloy wire and zinc alloy wire in the present invention are the same, the preparation methods of magnesium alloy wire and zinc alloy wire can be introduced only by taking magnesium alloy wire as an example, which mainly includes the following steps: turning a certain height Cylindrical wire-extruding blanks; hot-extruding cylindrical-shaped wire-extruding blanks at a certain temperature to obtain magnesium alloy and zinc alloy wire blanks with a diameter of φ1~2mm; multi-pass drawing of wire blanks , Rolling deformation and auxiliary heat treatment can obtain fine wires with different wire diameters.

[0027] The morphology of the biodegradable mixed weaving composite patch prepared in the present invention can be as follows figure 1 As shown, it can also be figure 2 shown.

Embodiment 1

[0029] 1) The Mg-Zn-Zr alloy thin wire with a circular diameter of 0.05 mm and the Zn-Cu alloy thin wire with a diameter of 0.05 mm prepared by the above method are braided into a thin rope (such as 2 strands) on a braiding machine. Magnesium wire and 1 strand of zinc wire are woven into a thin rope), and then the aforementioned thin rope is woven into a net, and the size of the net can be cut arbitrarily.

[0030] 2) After electrolytic polishing, cleaning, drying, packaging and sterilization, it is ready for use.

[0031] The thickness of the final product is 0.1mm, and the area of ​​a single mesh is 0.1mm 2 .

Embodiment 2

[0033] 1) Mg-Zn-Gd-based alloy filaments with an elliptical cross-section, a major axis of 0.05 mm and a short axis of 0.04 mm and Zn- The Fe alloy wires are woven into nets on the knitting machine, which can be cut arbitrarily.

[0034] 2) After electropolishing and cleaning.

[0035] 3) Degradable coating treatment.

[0036] 4) Dry, package, and sterilize before use.

[0037] The thickness of the final product is 0.2mm, and the area of ​​a single mesh is 1mm 2 .

Abstract

The invention provides a magnesium alloy and zinc alloy wire hybrid composite sticking patch and application thereof. The magnesium alloy and zinc alloy wire hybrid composite sticking patch is formedthrough mixed weaving of a magnesium alloy wire material and a zinc alloy wire material, and provided with a net structure. The composite sticking patch has the advantage that 1, the sticking patch iscompletely degradable, and absorbed and metabolized by human body in the recovering process from disease, the sticking patch has the good supporting effect in the early implanting stage, and is completely degraded, absorbed and replaced by autologous tissue after tissue recovering is completed in the late stage, and long-term complications caused by a traditional material can be avoided; and 2, by adjusting the size, the appearance and the weaving method of the whole wire material, the composite sticking patches in different types can be obtained, and the sticking patches have different strength and different degradation and absorption time, and can be adaptive to different illness states.

Description

technical field [0001] The invention relates to a composite patch made of magnesium alloy and zinc alloy wire and its application, which belongs to the technical field of medical consumables. Background technique [0002] Mesh has a wide range of clinical applications in disease treatment and plastic surgery. On the one hand, many disease treatments require the use of tissue repair patches. For example, it is very difficult to repair large tissue defects in the chest wall, abdominal wall, etc., and patches are often used in clinical surgical treatment. Secondly, a hernia means that an organ leaves its original location and enters another location through a weak point or defect or a hole in the human body. Mesh is also needed in the process of surgical treatment. Thirdly, female pelvic floor dysfunction is a gynecological disease with stress urinary incontinence, pelvic organ prolapse and chronic pelvic pain as the main symptoms. Compared with hysterectomy, it improves the...
