The present invention relates to a biodegradable biomedical composite material wire and its preparation method and application, belonging to the field of composite material technology. The present invention provides a preparation method for biodegradable biomedical composite material wire, comprising the following steps: mixing biodegradable polymer with bioceramic powder to obtain a mixed material; Blend the obtained mixed material with the dispersant itaconic acid acrylic acid copolymer in a high-speed mixer to obtain a uniform mixture; The mixture obtained from the steps is first melted and extruded through a twin-screw extruder for granulation, and then extruded through a single screw extruder to prepare the biodegradable biomedical composite material wire. The biodegradable biomedical composite material wire prepared by the present invention has the characteristics of high material uniformity and low polymer crystallinity, better toughness and ductility, and improves the biological affinity and biodegradability of polymer and ceramic composite materials in vivo.
