Description

Technical Field

[0001] The utility model relates to the technical field of minimally invasive spinal positioning, in particular to a minimally invasive spinal surgery robot-assisted positioning device. Background Art

[0002] Since minimally invasive spinal surgery causes less traction and stripping of soft tissue, it can reduce postoperative pain and shorten recovery time. In addition, minimally invasive spinal surgery can perform limited resection of bony structures, thereby reducing the possibility of postoperative spinal instability. Minimally invasive spinal surgery mainly includes microdiscectomy under minimally invasive channels, minimally invasive lumbar hemilaminectomy, transforaminal lumbar interbody fusion, lateral lumbar interbody fusion, and minimally invasive posterior fixation technology. In conventional minimally invasive spinal surgery, doctors adjust the surgical instruments to coincide with the ideal surgical path based on their surgical experience and skills 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, and complete the surgical positioning. However, when doctors perform surgery for a long time, it is easy to affect the positioning accuracy, which in turn affects the safety of minimally invasive spinal surgery.

[0003] For example, the prior art publication number is CN207821913U, which is an auxiliary spinal minimally invasive surgery positioning system. This utility model has position indication marks, which can assist doctors to quickly and accurately locate the surgical path and shorten the operation time; it can greatly reduce the number of X-rays taken during the operation and reduce the radiation of doctors and patients.
