Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to an auxiliary tool and device for minimally invasive lumbar surgery. Background Art

[0002] Minimally invasive disc surgery refers to a surgical concept that achieves the best surgical effect with minimal invasion and minimal physiological interference without affecting the efficacy. Its most important feature is that it causes minimal trauma to the human body compared to conventional surgery. Minimally invasive disc surgery includes many technical fields, mainly the following four aspects: (1) Using surgical microscopes or high-power magnifying glasses to magnify the surgical field of view for surgical operations, and performing "keyhole surgery" through the smallest possible skin incision, so that spinal surgery can perform the most effective treatment with minimal iatrogenic damage. It includes anterior cervical discectomy under surgical microscope, posterior lumbar discectomy under microsurgery (median approach, lateral approach, extraforamen approach), etc. (2) Endoscopic-assisted spinal surgery technology. Through several skin channels or tiny incisions to reach the spine, the operation is performed under direct vision using fiberoptic imaging technology. Endoscopic-assisted spinal surgery technology can be divided into thoracic, laparoscopic-assisted and microendoscopic-assisted spinal surgery. (3) Percutaneous spinal surgery technology. Minimally invasive spinal surgery is performed through percutaneous puncture or tiny incisions, using special instruments and devices. (4) Navigation-assisted spinal surgery. This is a new technology developed in the late 1990s. With the assistance of navigation systems, it has significantly improved the accuracy and safety of surgery and reduced complications.
