Implant System for Fixation of Cranial Bone Flaps After Craniotomy for Brain Surgery

At the end of the operation to start the fixation of cranial bone flaps, at least three Skull Grip titanium clamps will be positioned equidistant to one another along the craniotomy opening. The lower parts (complete circle) will be inserted between the dura and the cranium. The linear parts of the superior semicircle have to be in line with the craniotomy borders to allow the lodging of the bone flap. The different heights of the device are finalized to suit it for the different thickness of the cranial vault. The same procedure will be performed with all remaining Skull Grip titanium clamps.The bone flap will be then placed in its original position. By using a forceps, a simple and easy clockwise rotation of the superior semicircle will allow to block the SKULL GRIP clamp in place. For simple removal if necessary of the Skull Grip titanium clamps, even if bone ossification of the craniotomy edges has already occurred, it will be necessary just to lift up the superior semicircle of the Skull Grip by a forceps and to cut by a cutting forceps the pin between the two circle. Then, craniotomy could be completed in a standard way.
