[0001] This utility model relates to the field of puncture guide plate technology, and in particular to a puncture guide plate for percutaneous endoscopic discectomy for spinal diseases. Background Technology

[0002] Percutaneous endoscopic discectomy (PED) is a minimally invasive surgery primarily used to treat spinal-related diseases such as herniated discs, spinal stenosis, and other spinal lesions. Using PED technology, doctors can directly access the target area of ​​the spine through a very small incision using an endoscope and related tools, minimizing damage to surrounding tissues. Furthermore, a puncture guide can be used during the puncture to make the puncture more precise.

[0003] Most existing puncture guides have fixed guide holes, requiring the puncture location to be determined by the patient through preoperative imaging before manufacturing. However, the manufactured puncture guide can only be used by that patient and cannot be adapted to other patients, leading to increased costs. Therefore, those skilled in the art have provided a puncture guide for percutaneous endoscopic discectomy for spinal diseases to solve the problems mentioned in the background art. Summary of the Invention
