Trephine Protection Tube, Stepped Window – 9.0 mm OD, 95 & 145 mm
The Trephine Protection Tube with Stepped Window is a working sleeve that guides and shields a trephine during bone cutting in minimally invasive and endoscopic spine surgery. It has a 9.0 mm outer diameter and an 8.2 mm inner diameter, and comes in two working lengths: 95 mm and 145 mm.
The distal end has a stepped (graded) window: an angled opening with a distinct step in its edge, leaving a short protective lip at the tip. This lip can be placed against sensitive structures such as nerves and the dura to shield them, while the open side gives the trephine access to bone. The step also helps the tube sit securely against bony edges, which keeps it stable during cutting. The smooth, rounded edges help it slide into position with minimal trauma to soft tissue.
The thin-walled design gives a large 8.2 mm inner channel, so the trephine passes through freely and stays on a straight, controlled path. The two lengths suit both shorter and deeper approaches. The tube is made from high-grade surgical stainless steel, so it is durable, corrosion-resistant, and can be autoclaved for repeated sterilization.
