High molecular human body implant and its preparing method and use

Abstract

The invention discloses a preparation process and method of a human body polymer implant and the application of the implant. The material provided by the present invention is made of the formula provided by the present invention through resin hot pressing. It has high strength and good toughness during the bone healing period after implantation, and its shape can be reprocessed as required; It begins to degrade at four weeks, and can be completely absorbed in one and a half to two years; it does not produce effusion and sinus tracts, and can be made into fixation blocks, plastic blocks, fasteners and sutures for rejoining wounds and broken bones. The cost is greatly reduced, and it is an ideal polymer implant for human body.

Description

Technical field:

[0001] The invention relates to a human body absorbable polymer human implant, a preparation method, a product and an application thereof. Background technique

[0002] At present, Finland and some European countries have used a kind of polymer human body implant material that can be absorbed by the human body to fix broken bones in medicine, and use this material to make fixation rods and bone screws for fixing broken bones. . This material is made of polyethylene glue (PGA for short) and polypropylene glue (PLA for short) as raw materials through polymer polymerization. (PLA) and (PGA) fixed rods and bone screws have the following disadvantages in medical applications;

[0003] 1. About the degree of degradation

[0004] After the human implant is implanted into the human body, it should be dissolved or decomposed within an appropriate time without producing harmful substances to the human body. This dissolution or decomposition is called degradation. ...
