Beschreibung
Zusammenfassung:	The invention discloses an expansion fusion cage for posterior lumbar fusion, and belongs to the technical field of medical instruments, the expansion fusion cage comprises a frame body, two groups of auxiliary positioning mechanisms, a main positioning mechanism, an expansion mechanism, a locking frame and an operating forceps mechanism, the main positioning mechanism is slidably connected to the middle of the frame body, and the main positioning mechanism is slidably connected to the frame body. The auxiliary positioning mechanisms are symmetrically arranged on the two sides of the main positioning mechanism, the auxiliary positioning mechanisms are slidably connected to the frame body, the expansion mechanisms are symmetrically arranged on the two sides of the frame body, the locking frame is horizontally slidably connected to the two sides of the frame body, and the operating forceps mechanism is arranged on one side of the frame body. During implantation, the size of the frame body is minimum, so that th
