技术领域Technical field
本发明涉及一种外科器械，特别是涉及一种辅助脊柱微创手术路径定位装置。The present invention relates to a surgical instrument, in particular to an auxiliary minimally invasive spinal surgery path positioning device.
背景技术Background technique
由于脊柱微创手术对软组织的牵拉和剥离较少，因而能够降低术后疼痛，缩短恢复时间；并且微创脊柱手术对骨性结构进行有限切除，进而减少术后脊柱失稳的可能。因此，在过去的十年中，微创脊柱外科技术得到了迅速的发展。微创脊柱外科手术主要包括微创通道下显微椎间盘髓核摘除术、微创腰椎半椎板切除术、经椎间孔腰椎椎间融合术、侧方腰椎椎间融合术、微创后路固定技术。相比传统的开放手术，由于需要在透视引导下进行微创隧道定位，因此，虽然脊柱微创外科手术创伤小，但外科医生接受的射线剂量是传统手术的10至12倍。Because minimally invasive spine surgery involves less traction and stripping of soft tissue, it can reduce postoperative pain and shorten recovery time; and minimally invasive spine surgery involves limited resection of bony structures, thereby reducing the possibility of postoperative spinal instability. Therefore, minimally invasive spine surgical techniques have developed rapidly over the past decade. Minimally invasive spine surgery mainly includes minimally invasive microdiscectomy, minimally invasive lumbar hemilaminectomy, transforaminal lumbar interbody fusion, lateral lumbar interbody fusion, and minimally invasive posterior approach Fixation technology. Compared with traditional open surgery, minimally invasive spinal surgery requires minimally invasive tunnel positioning under fluoroscopic guidance. Therefore, although minimally invasive spine surgery is less invasive, the radiation dose received by the surgeon is 10 to 12 times that of traditional surgery.
常规脊柱微创手术，医生根据手术经验与技巧，通过目测正位与侧位X光图像里手术器械相对于手术对象路径的角度和距离，调节手术器械使其和理想手术路径重合来完成手术定位。这种方法严重依赖医生的手术经验与技巧。由于脊柱的解剖结构复杂性和医生观察脊柱手段的局限性，手术的难度很大；脊柱钻孔精度不高、钻孔操作过程中偏离设定路径；另外，X射线透视的反复使用使医生、患者和相关人员长时间暴露在放射线辐射下。因此本发明旨在提供一种操作简便灵活、适用范围广、可精确调节位置的辅助脊柱微创手术路径定位装置。For conventional minimally invasive spinal surgery, the doctor completes the surgical positioning by visually observing the angle and distance of the surgical instruments relative to the path of the surgical object in the anteroposterior and lateral X-ray images based on surgical experience and skills, and adjusting the surgical instruments to coincide with the ideal surgical path. . This method relies heavily on the doctor's surgical experience and skills. Due to the complexity of the anatomical structure of the spine and the limitations of doctors' means of observing the spine, the operation is very difficult; the accuracy of spinal drilling is not high, and the drilling operation deviates from the set path; in addition, the repeated use of X-ray fluoroscopy makes the doctor, Patients and related personnel are exposed to radiation exposure for long periods of time. Therefore, the present invention aims to provide an auxiliary spinal minimally invasive surgery path positioning device that is simple and flexible to operate, has a wide range of applications, and can accurately adjust the position.
