Embodiment 1

[0044] 1) Twisting two bundles of 6k carbon fibers into a carbon fiber rope with a twist of 200 twists / m; then weaving 24 twisted carbon fiber ropes into a strip-shaped continuous carbon fiber braid. The area density is 30g / m2 by needle needle 2 The carbon fiber nonwoven fabric is riveted on the continuous carbon fiber braid, and the riveting point density is 10 points / cm 2 , to obtain the prefabricated body of carbon fiber sternum slice. Weave 2 bundles of 6k carbon fiber twisted ropes with a twist of 200 twists / m, and 10 twisted carbon fiber ropes into a strip to obtain a prefabricated carbon fiber clavicle strip. Two bundles of 6k carbon fiber twisted ropes with a twist of 200 twists / m are braided into strips, and then spirally wound into a spring through a rod-shaped carbon material mold with one coil to obtain a carbon fiber joint prefabricated body. Extend the carbon fiber at both ends of the joint prefabricated body into the carbon fiber at the connecting end of the c...

Abstract

The invention discloses a sternum-lock integrated part, which comprises a sternum piece, a clavicle strip and a joint connecting the sternum piece and the clavicle strip. matrix carbon and / or silicon carbide filled between fabrics and its carbon fibers; clavicle strips are strip-shaped, containing twisted carbon fiber rope braids and matrix carbon and / or silicon carbide filled between carbon fibers, or, containing twisted carbon fiber rope A laminated layer of braided fabric and carbon fiber nonwoven fabric and matrix carbon and / or silicon carbide filled between carbon fibers; the joint is spring-like, including a spring body woven from twisted carbon fiber ropes and carbon fibers filled between them. matrix carbon and / or silicon carbide. The one-piece chest lock has the characteristics of light weight, good biocompatibility, good chemical stability, similar mechanical properties to human bones, good fatigue resistance, strong designability, and no artifacts, and is especially suitable for the reconstruction of the one-piece chest lock. .

Description

technical field [0001] The invention relates to a chest lock integrated part, in particular to a carbon fiber composite material chest lock integrated part and a preparation method thereof, belonging to the technical field of biomedical materials. Background technique [0002] Due to tumor and trauma, a large area around the sternoclavicular joint was resected. In order to maintain the integrity and function of the chest wall, sternoclavicular joint reconstruction was required. The commonly used sternoclavicular materials in the prior art are replaced with metal materials such as titanium, titanium alloys, nickel-titanium alloys, and stainless steel, which have poor mechanical properties and compatibility with autogenous bone, loosening or dislocation of implants, and local osteoporosis , bone resorption, fracture, delayed bone healing and many other problems. Carbon materials have good biocompatibility and have been applied in many aspects of biomedicine. However, there ar...
