[0052] In the first embodiment of the present invention, a degradable wire is provided. figure 1 It is a schematic structural diagram of the degradable wire according to the first embodiment of the present invention. Please refer to figure 1 , the degradable wire in this embodiment includes:

[0053] A matrix 1 comprising absorbable medical sutures;

[0054] The conductive part 2, including a degradable metal layer, wraps the outer surface of the substrate; and,

[0055] The protection part 3 includes a degradable polymer material layer for encapsulating the conductive part.

[0056] Specifically, the absorbable medical sutures include: sheep catgut (ordinary catgut, chrome catgut), pure natural collagen sutures, chemical synthetic threads (PGA, PGLA, PLA) and the like.

[0057] Furthermore, since the absorbable medical suture has good plasticity, it can be straightened before wrapping the metal.

[0058] The material of the degradable metal layer is a pure metal material...

[0077] In the third embodiment of the present invention, a degradable wire is provided. image 3 It is a schematic structural diagram of the degradable wire according to the third embodiment of the present invention. Please refer to image 3 , the degradable wire in this embodiment includes:

[0078] The matrix 6 includes degradable polymer wires;

[0079] The conductive part 7, including a degradable metal layer, wraps the outer surface of the substrate; and,

[0080] The protection part 8 includes a degradable polymer material layer for encapsulating the conductive part.

[0081] Specifically, the degradable polymer wire can be obtained from the prepared polymer film by cutting.

[0082] The degradable metal layer adopts pure metal materials or metal alloys, including pure magnesium and magnesium-based alloys, pure iron and iron-based alloys, pure zinc and zinc-based alloys, tungsten and (calcium-based, zinc-based and strontium-based) bulk Amorphous alloys, etc.

[0103] Please refer to Figure 5 , the preparation method of the degradable wire in this embodiment includes:

[0104] Using degradable metal wires to form the matrix of degradable wires;

[0105] A degradable polymer material layer is packaged outside the degradable metal wire, that is, a protective part of the degradable wire is formed.

[0106] Since the degradable polymer material exists in solid form, the encapsulation of the metal layer by the degradable polymer material can be completed through processes such as solvent dissolution and solvent volatilization.

[0107] Advantageously, the material treatment methods used in the experiment can be chemical etching, filing, surface plasma treatment, etc., and the metal wires are completely exposed.

Abstract

The invention provides a degradable conducting wire. The degradable conducting wire comprises a substrate and a protective part. The substrate and the protective part are formed by adopting absorbableor degradable materials, wherein the protective part is used for encapsulating the degradable conducting wire. The invention also provides a preparation method of the degradable conducting wire. Thedegradable conducting wire and the preparation method thereof disclosed by the invention have the advantages of simple preparation process, wide raw material sources, low economic cost, stable performance and capability of being used for large-scale batch production; by means of the degradable conducting wire, the problems that conducting wires of electronic devices at the current stage cannot bedegraded and the like are effectively solved.

Description

technical field [0001] The invention relates to the technical field of wires, in particular to a degradable wire and a preparation method thereof. Background technique [0002] With the development and progress of medicine and the improvement of people's living standards, people have higher and higher requirements for the quality of equipment and materials used. The study of biomaterials is an important branch of biomedical engineering, and biodegradable materials are one of the focuses of biomaterials research in recent years. Because it can be degraded into non-toxic small molecular substances under physiological conditions in the body, and excreted with normal metabolism in the body, it is more and more widely used in medicine. The existing biodegradable materials can be divided into four categories: degradable metals, natural degradable materials, artificial degradable materials and biodegradable composite materials. Existing implantable medical devices generally conta...
