Description
发明名称:一种用于组织工程化软骨移植的微创胶原膜夹持器 技术领域
[0001] 本实用新型涉及骨科手术器械技术领域, 具体涉及一种用于组织工程化软骨移 植的微创胶原膜夹持器。
背景技术
[0002] 关节软骨缺损是一类常见疾病,常由运动损伤造成,好发于运动量较大的青年。
我国关节软骨损伤率高达 10~17%。 缺损软骨长期磨损会导致退行性的骨关节病 变
最终可发展为全骨关节炎。 (请给出是哪个国家) 的 (请给出中文名) Gerber 等人随访 1321个平均年齢在 36岁的关节软骨损伤患者, 发现约有 13.9%的患者在 65岁吋完全进展成为膝关节骨性关节炎, 比无关节软骨损伤病史人群的风险增 加 5.2倍。 在我国, 骨关节炎的患者约有 1亿人,且呈不断增加趋势,有相当大比 例的人需要做膝关节置换术。
[0003] 微创外科是临床医学界跨世纪的高新外科科技成就之一。 微创外科器械的代表 为内窥镜。 如利用一个钥匙孔大小的孔道或微小切口, 即可进行腹腔内脏器病 变切除、 畸形纠正、 修复或重建等各种外科手术, 最终达到治疗目的。 微创手 术不同于上世纪的外科手术之处在于, 前者能减少手术创口面积, 避免体内组 织的大幅度暴露而引起的感染, 以及能使病人更快痊愈, 缩短住院吋间和医疗 费用。 微创手术器械可将传统外科手术造成的体内创伤降低至最小程度。 因此 , 研究认为, 微创外科手术是一个"跨世纪的里程碑"。 如关节镜外科学即是微创 手术理念在骨科领域的重大进展, 是关节外科的发展方向。 国外从上世纪七十 年代幵始逐渐将其应用于临床, 我国在八十年代引进了这项技术。 近年随着医 学知识的发展和医疗器械的不断改进, 关节镜手术以其显著的优点被越来越多 的医生和病人所接受, 为广大关节疾病患者带来了福音。 经过几十年迅猛发展 , 现在已经应用于骨科的大部分领域, 尤其在膝关节镜外科技术方面, 各种新 方法更是层出不穷, 日新月异。
[0004] 随着以 "大创伤"为特征的幵放手术向以"微小创伤"为特征的微创手术方向发展 , 探索面向自然腔道的新一代微创手术器械已成必然趋势。 工欲善其事, 必先 利其器。 面对生命医学发展的需求, 探索先进手术器械创新设计与仿生制造的 科学原理是机械工程学科重要任务之一。 当前, 由于微创手术器械设计理念没 有根本性变革, 导致许多复杂精细手术无法完成。 长期以来, 我国在此方向基 础研究不足, 制约了微创手术器械技术的发展。 微创手术器械创成与制造的科 学基础涉及机械科学、 生命科学和临床医学等学科的交叉融合, 通过微创手术 器械的基础理论与方法研究, 将为临床医学提供新治疗原理与工具, 相关研究 将催生医疗技术的新变革。
[0005] 在组织工程化软骨移植的过程中, 由于没有关节镜下专用的手术器械, 需要幵 放手术, 暴露出软骨损伤部位后才能将骨膜或者生物膜进行关节内缝合, 缝合 后再进行细胞回植操作, 产生的切口较大影响美观, 而且缺乏关节镜下的放大 监视作用, 仅靠术者本身所具有的手术经验, 所以需要镜下软骨移植专用设备 , 从而使关节镜下软骨细胞移植手术成为可能。
[0006] 首先需要解决的就是关节镜下对胶原膜的夹取工作, 由于目前, 关节镜手术器 械没有专用于软骨移植的器械种类, 而且自体软骨细胞移植所使用的生物胶原 膜, 非常脆弱, 非常容易破损。 而现有关节镜器械镜下夹取均是使用髓核钳, 但是髓核钳无法进行精细温柔的操作。
[0007] 因此, 针对现有技术中的存在问题, 亟需提供一种操作精细、 扩张范围小的一 种用于组织工程化软骨移植的微创胶原膜夹持器技术显得尤为重要。
