Medtronic 7BA20 Midas Rex 7-6ST Legend Bur Attachment 7cm x 2mm Dissecting Tool

• Model: 7BA20
• Length (Shaft): 7cm
• Head Diameter: 2mm
• Tip/ Working End: Ball Style
• Edge/ Flute Type: Fluted Edge, Small Bore

The 7BA20 Legend bur is designed as a precision cutting tool with moderate aggressiveness—its 2 mm diameter ball tip gives a balance between fine, controlled contact and enough cutting surface to remove meaningful amounts of bone. The fluted edge geometry (with helical or curved cutting flutes) assists in chip removal and helps prevent clogging; it also allows irrigation fluid (if used) access to the cutting site so heat is dissipated. Being ball‑ended rather than sharp or tapered means that contact is smoother and somewhat safer around irregular surfaces, especially where there’s a risk of cutting into sensitive tissue.

At 7 cm shaft length, the tool offers sufficient reach for many surgical locations—deep cavities, tight anatomical corridors, or sites where direct line‐of‐sight is limited—while not being so long as to overly compromise stability. The small bore Legend attachments are lighter and lower profile, which helps reduce hand fatigue and minimizes vibration. The 2 mm size is also a compromise: small enough for delicate trimming, finishing, or reaching localized areas; yet large enough that removal of bone is more efficient than with ultra‑fine (1 mm or less) burs, so it can serve both finishing and moderate resection tasks.

In terms of surgical use, the 7BA20 is well suited to ENT, neurosurgery (skull base, cranial vault windows, inner decompressions), spinal procedures (foraminotomy, osteophyte removal), and where bone needs to be shaped rather than simply removed in bulk. Surgeons might select this tool after using a coarser bur to open up a space, then switching to a 2 mm ball bur to smooth edges, sculpt curves, refine surfaces, or approach delicate structures with better control. The tool’s single‑use, sterile design helps maintain sharpness and precise geometry, important for consistency and safety. The trade‑offs include slower removal vs larger diameter tools, more care needed to avoid overheating, and being cautious about lateral forces (since larger pressure may cause vibration or chatter with a small ball tip).
