Patent attributes
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.
