Description

抑制钛及钛合金骨整合的骨科植入物
技术领域
本实用新型涉及骨治疗技术领域，特别涉及一种抑制钛及钛合金骨整合的骨科植入物。
背景技术
钛及钛合金由于具有优异的力学性能、生物相容性、耐腐蚀性能，特别是与不锈钢相比更低的弹性模量，使其在骨科医疗器械领域特别是创伤产品领域得到了广泛的应用。然而由于骨科器械往往需要二次手术取出，特别是创伤产品在创伤愈合后需要通过手术取出植入物。由于钛及钛合金所具有的骨整合作用，使得骨容易在其表面上生长，特别是螺纹部位的骨，给植入物的取出带来了难度。在取出上述植入物时，医生需使用专门工具剔除骨方能顺利取出植入物，延长手术时间，增加患者痛苦。
实用新型内容
本实用新型的目的是克服现有技术存在的缺陷，提供一种可抑制钛及钛合金骨整合作用，使得骨不易在其表面上生长，从而使植入物易于取出的抑制钛及钛合金骨整合的骨科植入物。
实现本实用新型目的的技术方案是：一种抑制钛及钛合金骨整合的骨科植入物，具有植入物；所述植入物上覆盖无骨整合层；所述无骨整合层的厚度为0.01mm～0.5mm。
上述技术方案所述无骨整合层为聚醚醚酮层或聚乙烯层或聚甲基丙烯酸甲酯层或聚乳酸层。
上述技术方案所述无骨整合层的厚度为0.1mm。
上述技术方案所述无骨整合层为聚乳酸层。
上述技术方案所述无骨整合层的厚度为0.3mm。
一种抑制钛及钛合金骨整合的骨科植入物的制备方法，将机加工完成后的植入物经抛光、喷砂、酸蚀、清洗后，浸入熔融态或已溶入溶剂中的的无骨整合材料中，并匀速旋转，以控制涂覆厚度为0.01mm～0.5mm。
上述技术方案所述植入物为接骨螺钉或锁定螺钉或接骨板。
采用上述技术方案后，本实用新型具有以下积极的效果：
(1)本实用新型可抑制钛及钛合金骨整合作用，可使骨不易在钛及钛合金骨科植入物的表面生长，从而使得植入物易于取出，减少手术时间，降低患者痛苦。
