Cannulated Medical Titanium Bar

Some surgical implants need a hole down the middle. Guide wire goes through. Screw slides over. Needle passes inside.

Cannulated medical titanium bar is hollow. Tube, not solid. But called bar because the wall is thick. Strong enough for load-bearing. Hollow enough for a guide wire.

Cannulated screws. Intramedullary nails with guide wire channels. Surgical drills. Biopsy needles. Arthroscopic instruments.

Solid bar works for many implants. But sometimes you need to place a screw over a guide wire. The wire goes in first. X-ray confirms position. Then the screw goes over the wire.

Cannulated design makes this possible. The hole in the center guides the implant exactly where the wire went.

For cannulated medical titanium bar, the cannulation is precision drilled. Centered. Straight. Smooth inside.

Grade 23 ELI is standard for cannulated screws. High strength needed. Thin wall. Small diameter.

Grade 4 is used for surgical instruments and non-load-bearing applications. Easier to machine.

For cannulated medical titanium bar, Grade 23 ELI covers most implant applications.

Chemical limits: Oxygen ≤0.13%, Iron ≤0.25%. No nickel.

Wall thickness typically 0.6mm to 1.5mm. Must be strong enough not to collapse under torque.

Cannulated screws. Hip fractures. Femoral neck. Screw goes over guide wire. Wire placed under X-ray. Screw follows exactly. 4.0mm to 8.0mm outer diameter. Grade 23 ELI.

Cannulated nails. Intramedullary nails with central channel. Guide wire keeps nail aligned. Larger diameter. 8.0mm to 12.0mm outer.

Surgical drills. Hollow drill bits. Saline or suction through center. 2.0mm to 5.0mm.

Biopsy needles. Outer cannula. Inner stylet. Tissue sample through the center. Small diameter. 1.5mm to 3.0mm.

Arthroscopic instruments. Shavers. Punches. Suction through the center.

For cannulated medical titanium bar, each application requires precise concentricity. Inner hole centered. Wall thickness even.

If the inner hole is off-center, the wall is thin on one side, thick on the other. Thin side collapses under torque. Screw strips. Implant fails.

We hold these tolerances. Every bar gets measured.

Cannulated bar contacts tissue. Smooth surface reduces friction. Helps screw insertion.

For cannulated medical titanium bar, polished is standard for implant applications.

Solid bar starts as medical grade rod. Deep hole drilling. Specialized equipment. Drill bit goes through the center. Coolant flushes chips out.

Then grinding. Outer diameter ground to tolerance. Straightened. Polished.

Inspection. Camera down the hole. Checks inner surface. No burrs. No steps. Smooth.

For cannulated medical titanium bar, the inner surface is as important as the outer. Rough inside catches the guide wire.

Cannulated screws need threads. Thread rolling after drilling.

Challenge: Thin wall. Rolling pressure can collapse the tube.

Solution: Proper support. Mandrel inside during rolling. Controlled pressure.

We supply cannulated bar. You roll threads. Or we can supply finished cannulated screws to your print.

Cannulated implants are medical devices. Full traceability required.

Every cannulated medical titanium bar comes with heat number, mill test report, ASTM F136 or F67 cert, chemical analysis, and mechanical test results.

EN 10204 3.1 standard. 3.2 available.

Cannulated implants go over guide wires. Precise placement. X-ray guided.

Cannulated medical titanium bar gives you the hollow starting stock.

Grade 23 ELI for screws. Concentric hole. Smooth inside. Strong wall.

For hip screws. For cannulated nails. For biopsy needles. For surgical instruments.

Hollow in the middle. Strong on the outside.
