pSpine is an instrument for spinal surgery that does not require additional fixation. The tool is made of stainless steel, making it easy to sterilise, and it consists of three parts: a guide handle, a screw lock and a slide hammer. The design of the slide hammer allows for a gradual installation of the spinal cage using metred force by restoring the height of the intervertebral space step by step. It also enables the user to rotate and extract the spinal cage.
