Abstract
A spinal fusion surgery instrument for implanting and an intervertebral cage thereof are provided. The spinal fusion surgery instrument includes a body, a gripper subassembly, a first control subassembly, and a second control subassembly. The first control subassembly is provided to generate a displacement between a first connecting member and a second connecting member of the gripper subassembly to change the angle of gripper of the intervertebral cage. The second control subassembly is provided to enable a first gripper member and a second gripper member of the gripper subassembly separating smoothly from the dowel pins of the intervertebral cage. By means of the operation model, the spinal fusion surgery instrument may be controlled easily, and the orientation of the intervertebral cage may be promoted in the process of the surgery.
