Trephine suite for minimally invasive spine puncture positioning

The invention relates to the technical field of spine endoscopic surgery, in particular to a trephine suite for spine minimally invasive puncture positioning, which comprises a trephine, an inner core, a puncture needle and a kirschner wire, the inner core is of a hollow cylindrical structure, and the puncture needle and the kirschner wire are both of cylindrical structures with tip ends at the lower ends. The inner core can be arranged in the trephine pipe body in a penetrating mode, and the outer diameter of the inner core is matched with the inner diameter of the trephine pipe body. The trephine is reasonable in structure, and through the arrangement of the trephine, when screw placement is guided through a kirschner wire in a minimally invasive spine screw placement operation, the initial puncture position is correct, and the puncture direction needs to be adjusted, the purpose of adjusting the puncture direction is achieved by adjusting the direction of the trephine; therefore, the situation that the ini
