Abstract: The present disclosure discloses an operating instrument for a spinal implant. The operating instrument includes an extension assembly, a central rod, and an operating handle. The extension assembly includes an outer sleeve, and one end of the outer sleeve is connected with a first part of the spinal implant. The central rod passes through the outer sleeve, and one end of the central rod connects to a second part of the spinal implant. The operating handle includes a fixing element, a rotating element, and a pushing element. The rotating element is sleeved on the outer side of the fixing element. The pushing element connects with the central rod, and the rotating element presses against the pushing element. The rotating element is rotated to cause the pushing element to drive the central rod to move the second part, thereby expanding the spinal implant.

Abstract: The present invention provides a spinal implant structure. The spinal implant structure comprises a first part, a second part and at least one expansion arm. The second part is disposed on the horizontal orientation of the first part and does not overlap with the first part. The diameter of the first part is larger than that of the second part. One end of the expansion arm is connected to the first part, and the other end of the expansion arm is free end. The expansion arm includes a supporting arm. One end of the supporting arm is connected to the expansion arm, and the other end is connected the second part. The support arm includes a plurality of structure weakness. When the distance between the first part and the second part changes, the support arm bends from the structure weakness, thereby the spinal implant structure is expanded.

Abstract: The present invention provides an intervertebral fusion apparatus for positioning and combining vertebrae, which use a solidifiable material and an intervertebral fusion cage concurrently. By diffusing the solidifiable material from the top or bottom surface of the intervertebral fusion cage, the contact area with vertebrae and hence the stability can be increased. In addition, the intervertebral fusion cage provided by the present invention can further include a wing member connected pivotally on the side and operated concurrently with the solidifiable material to change the shape and thus avoid slipping off the operation opening. By using the intervertebral fusion apparatus, the stability of the intervertebral fusion cage during and after surgeries can be improved effectively. Thereby, the success rate and safety of vertebral fusion surgeries can be increased.

Abstract: A bone plate structure adapted to fix a bone in an affected part is provided. The bone plate structure includes first and second bone plates. The first bone plate has a first stacking portion and a first extending portion and is adapted to be moved onto the bone through a wound of the affected part. The second bone plate has a second stacking portion and a second extending portion and is adapted to be moved onto the bone through the wound. When the first and second bone plates are located on the bone, the second bone plate is adapted to be moved relatively to the first bone plate, such that the first and second stacking portions are stacked with each other and the first and second extending portions are expanded relatively. A surgery device and a method for bone plate implant suitable for the bone plate structure is also provided.
