Description
说明书 发明名称：组织工程化软骨移植的微创手术器械 技术领域 Title: Inventive name: minimally invasive surgical instruments for tissue engineered cartilage transplantation
[0001] 本实用新型涉及一种医疗器械,特别是一种骨移植的微创手术器械。 [0001] The utility model relates to a medical device, in particular to a minimally invasive surgical instrument for bone transplantation.
背景技术 Background technique
[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。 [0002] Articular cartilage defects are a common type of disease, often caused by sports injuries, and occur in young people with a large amount of exercise.
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。 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。 The rate of articular cartilage damage in China is as high as 10~17%. Long-term wear of defective cartilage can lead to degenerative bone and joint lesions, which can eventually progress to total osteoarthritis. In China, there are about 100 million patients with osteoarthritis, and there is an increasing trend. A large proportion of people need knee replacement surgery.
[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。 [0003] Minimally invasive surgery is one of the scientific and technological achievements of high-tech surgery in the field of clinical medicine. The representative of minimally invasive surgical instruments is the endoscope. For example, a keyhole-sized hole or a small incision can be used for various surgical operations such as intra-abdominal organ disease resection, malformation correction, repair or reconstruction, and finally achieve therapeutic purposes. Minimally invasive surgery differs from the surgical procedures of the last century in that the former can reduce the area of surgical wounds, avoid infections caused by extensive exposure of tissues in the body, and enable patients to heal faster, shorten hospitalizations and medical expenses. Minimally invasive surgical instruments minimize the in vivo trauma caused by traditional surgery. Therefore, research suggests that minimally invasive surgery is a "cross-century milestone." For example, arthroscopic surgery is a major advancement in the field of orthopedics, and it is the development direction of joint surgery. Foreign countries gradually applied it to the clinic since the 1970s, and China introduced this technology in the 1980s. In recent years, with the development of medical knowledge and the continuous improvement of medical devices, arthroscopic surgery has been accepted by more and more doctors and patients with its remarkable advantages, which has brought good news to patients with joint diseases. After decades of rapid development, it has been applied to most areas of orthopedics, especially in the field of knee arthroscopy, and various new methods are emerging one after another.
[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。 [0004] With the development of minimally invasive surgery featuring "major trauma" to the development of minimally invasive surgery characterized by "small trauma", it has become an inevitable trend to explore a new generation of minimally invasive surgical instruments that face natural lumens. If a worker wants to do something good, he must first sharpen his tools. Facing the needs of the development of life medicine, exploring the scientific design of advanced surgical instruments and bionic manufacturing is one of the important tasks of mechanical engineering. At present, there are no fundamental changes in the design concept of minimally invasive surgical instruments, which has led to the inability to complete many complex and delicate operations. For a long time, my country is in this direction Insufficient basic research has restricted the development of minimally invasive surgical instrument technology. The scientific basis for the creation and manufacture of minimally invasive surgical instruments involves the cross-integration of disciplines such as mechanical sciences, life sciences, and clinical medicine. The basic theories and methods of minimally invasive surgical instruments will provide new therapeutic principles and tools for clinical medicine. Research will lead to new changes in medical technology.
[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。 [0005] In the process of tissue-engineered cartilage transplantation, since there is no surgical instrument dedicated to arthroscopic surgery, it is necessary to perform a scaling operation to expose the periosteum or biofilm to the intra-articular suture after exposing the cartilage injury site, and then suture the cells. The replanting operation produces a large incision which affects the appearance, and lacks the magnification monitoring effect under the arthroscope. Only the surgical experience of the surgeon itself requires a special device for cartilage transplantation under the microscope, so that the articular chondrocyte transplantation can be performed. Surgery is possible.
[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， 并且也不利于胶原膜等软性材料的缝合 技术问题 [0006] The first thing that needs to be solved is the arthroscopic clamping of the collagen membrane. At present, the arthroscopic surgical instruments do not have a special type of instruments for cartilage transplantation, and the bio-collagen membrane used for autologous chondrocyte transplantation is very fragile. Very easy to break. However, the existing arthroscopic instruments are clipped with nucleus pulposus, but the nucleus pulposus cannot perform fine and gentle operation, and it is not conducive to the suturing of soft materials such as collagen membrane.
[0007] 本实用新型的目的是提供一种组织工程化软骨移植的微创手术器械， 要解决的 技术问题是解决关节镜下胶原膜的缝合吋的夹取固定问题。 [0007] The object of the present invention is to provide a minimally invasive surgical instrument for tissue engineered cartilage transplantation, and the technical problem to be solved is to solve the problem of clamping and fixing of the suture fistula of the collagen membrane under arthroscopy.
