This study analyzes patents associated with minimally invasive spine surgery (MISS) found on the Lens open online platform.
The goal of this research was to provide an overview of the most referenced patents in the field of MISS and to uncover patterns in the evolution and categorization of these patents.
MISS has rapidly progressed, with a core focus on minimizing surgical damage, preserving the natural anatomy, and enabling swift recovery, all while achieving outcomes that rival traditional open surgery. While prior studies have primarily concentrated on MISS outcomes, the analysis of MISS patents has been limited.
To conduct this study, we used the Lens platform to search for patents that included the terms "minimally invasive" and "spine" in their titles, abstracts, or claims. We then categorized these patents and identified the top 100 with the most forward citations. We further classified these patents into 4 categories: Spinal Stabilization Systems, Joint Implants or Procedures, Screw Delivery System or Method, and Access and Surgical Pathway Formation.
Five hundred two MISS patents were identified initially, and 276 were retained following a screening process. Among the top 100 patents, the majority had active legal status. The largest category within the top 100 patents was Access and Surgical Pathway Formation, closely followed by Spinal Stabilization Systems and Joint Implants or Procedures. The smallest category was Screw Delivery System or Method. Notably, the majority of the top 100 patents had priority years falling between 2000 and 2009, indicating a moderate positive correlation between patent rank and priority year.
Thus far, patents related to Access and Surgical Pathway Formation have laid the foundation for subsequent innovations in Spinal Stabilization Systems and Screw Technology. This study serves as a valuable resource for guiding future innovations in this rapidly evolving field.
本研究分析了在Lens开放在线平台上找到的与微创脊柱手术（MISS）相关的专利。
本研究的目的是概述MISS领域中被引用最多的专利，并揭示这些专利在演变和分类方面的模式。
MISS发展迅速，其核心重点是将手术损伤降至最低、保留自然解剖结构并实现快速康复，同时取得与传统开放手术相当的效果。虽然先前的研究主要集中在MISS的结果上，但对MISS专利的分析却很有限。
为进行本研究，我们使用Lens平台搜索标题、摘要或权利要求中包含“微创”和“脊柱”字样的专利。然后我们对这些专利进行分类，并确定前100项被引用次数最多的专利。我们进一步将这些专利分为4类：脊柱稳定系统、关节植入物或手术、螺钉输送系统或方法以及通路和手术路径形成。
最初确定了502项MISS专利，经过筛选过程后保留了276项。在前100项专利中，大多数具有有效的法律状态。前100项专利中最大的类别是通路和手术路径形成，紧随其后的是脊柱稳定系统和关节植入物或手术。最小的类别是螺钉输送系统或方法。值得注意的是，前100项专利中的大多数优先权年份在2000年至2009年之间，表明专利排名与优先权年份之间存在适度的正相关。
到目前为止，与通路和手术路径形成相关的专利为脊柱稳定系统和螺钉技术的后续创新奠定了基础。本研究是指导这一快速发展领域未来创新的宝贵资源。
