摘要:

文题释义:
心脏组织工程:是通过将生物学、材料学、工程学等方法相结合用以修复及再造心脏的组织工程方法。心脏组织工程针对心血管疾病的治疗做了很多探索,如人工心脏、心脏补片、人工瓣膜、可注射化材料等。
专利分析:是研究某技术领域发展情况和态势最有效且最准确的方法。通过对全球范围内的专利数据进行科学统计和深入分析,来反映该领域技术发展的趋势特点、发展态势和重要的研发力量,从而为各机构提供决策参考。

背景:组织工程是修复或替代器官功能衰竭或组织缺损的最佳途径,且发展非常迅速。随着心血管疾病已成为危害人类健康的最危险因素之一,心脏组织工程的研究亦取得了巨大进展。 
目的:对心脏组织工程领域的全球专利进行分析,揭示全球技术竞争态势,为中国心脏组织工程的发展与创新提供借鉴和参考。
方法:对心脏组织工程领域近20年的全球专利申请与授权趋势、专利技术发源地、专利受理国家/地区分布、申请机构、发明人和热点技术领域进行定性分析和定量分析,并用数据可视化的方式呈现全球心脏组织工程的技术开发现状与趋势和中国的发展现状。
结果与结论:①全球心脏组织工程领域的技术发展较快,创新性强,发明专利占比93.91%;②中国心脏组织工程领域技术开发规模不及美国,但增速远超美国,并积累了一定数量的高质量技术成果,成为全球第二大技术发源地;③美国是心脏组织工程领域最受关注的目标市场,中国市场目前排名第4位,且中国心脏组织工程近几年来发展迅速,增速远超美国;④中国有3家机构的技术开发规模跻身世界前列,但缺乏潜在市场价值较高的技术成果,与美国还有一定差距;⑤中国发明人在该领域已取得一定成果,主要分布在企业;⑥该领域科技创新的主要领域为心脏瓣膜被覆材料和细胞支架;⑦通过对心脏组织工程领域专利进行深入全面分析,可以发现全球心脏组织工程领域开发活跃,创新性强,但普遍缺乏高质量成果,美国为该领域最受关注的目标市场和最主要的技术发源地。中国在该领域处于快速发展的阶段,企业和高校还应加强合作,聚焦研究热点,提高技术竞争力。

Abstract: BACKGROUND: Tissue engineering is the best way to repair or replace organ failure or tissue defects. From the theoretical point of view to the research in many fields, tissue engineering has developed very rapidly. As cardiovascular disease has become one of the most dangerous factors that endanger human health, research on cardiac tissue engineering has made tremendous progress.
OBJECTIVE: To provide advices and references for the development and innovation of cardiac tissue engineering based on patent analysis in the field of cardiac tissue engineering that reveals the global competitive situation of cardiac tissue engineering.
METHODS: We qualitatively and quantitatively analyze the number and development tendency, technology birthplaces, target markets, applicants, inventors and technical fields of patents in the field of liver tissue engineering in nearly 20 years. The data visualization method is used to present the current status and tendency of global cardiac tissue engineering technology development and China's development status.
RESULTS AND CONCLUSION: The technology for cardiac tissue engineering has been evolved rapidly and highly innovative, with invention patents accounting for 93.91%. The scale of technological development in the field of cardiac tissue engineering in China is not expanded as large as that in the United States, but the growth rate is far faster than that in the United States, and it has accumulated a certain number of high-quality technological achievements, becoming the second largest source of technology in the world. The United States is the most concerned target market in the field of cardiac tissue engineering, and the Chinese market currently ranks fourth. Chinese cardiac tissue engineering has developed rapidly in recent years, growing much faster than that in the United States. There are three institutions in China that has mounted to the front of the world in terms of technology development. Due to a lack of technological achievements with high potential market value, there is still a certain gap between China and the United States. Chinese inventors have achieved certain results in this field, mainly in enterprises. The main fields of technological innovation in this field are heart valve covering materials and cell scaffolds. Through an in-depth and comprehensive analysis of patents in the field of cardiac tissue engineering, it can be found that the global development of cardiac tissue engineering is active and innovative, but generally lacks high-quality results. The United States is the most concerned target market in this field and the most important technology birthplace, whereas China is at a stage of rapid development in this field. In order to improve technological competitiveness, enterprises and universities should strengthen cooperation and focus on research hot spots.
