Trephine Protection Tube - Oblique, flat tip

Trephine Protection Tube, Oblique Flat Tip – 9.0 & 10.0 mm OD

The Trephine Protection Tube is a working sleeve that guides and shields a trephine during bone cutting in minimally invasive and endoscopic spine surgery. It comes in two sizes, 10.0 mm and 9.0 mm outer diameter, with working lengths of 195 mm and 215 mm.

The tube has an oblique (bevelled) opening with a flat tip. The longer side of the bevel acts as a protective shield: it can be placed between the trephine and sensitive structures such as nerves and the dura, so cutting happens only on the open side. The flat, blunt tip sits steadily against bone without cutting into soft tissue, which keeps the tube stable while the trephine works inside it.

The large inner channel (9.0 mm or 7.0 mm) lets the trephine pass through freely and keeps it on a straight, controlled path. The slotted proximal end connects to the Handle for Protection Tube (Art. No. 65-07-0030), so the surgeon can rotate the tube to turn the protective side exactly where it’s needed. The tube is made from high-grade surgical stainless steel, so it is durable, corrosion-resistant, and can be autoclaved for repeated sterilization.
