XC N-Series Cannulate Drill

General orthopaedic trauma theatres use cannulate drills for guided fixation in fracture repair, intramedullary nail preparation, and cannulated screw placement, where the 4.0 mm cannula constrains the drill path to the pre-positioned guidewire and eliminates freehand angular error. The N Series Cannulate Drill, available through Medigear.uk, provides variable speed from 0 to 1000 rpm — a slightly lower ceiling than standard bone drills, suited to the controlled penetration rate preferred in guided cannulated technique. CE Certification and ISO 13485-aligned documentation support the institutional approval requirements of hospital trauma programmes and NHS procurement frameworks.

In joint arthroplasty and reconstruction procedures requiring cannulated pin placement and guided drilling, the ≤ 0.05 mm run-out of the N Series Cannulate Drill ensures the drill follows the guidewire accurately through the full depth of the bone channel, which directly affects implant seating and alignment. The detachable chuck converts the handpiece to a standard 0.7-6.5 mm drilling mode between cannulated steps, reducing the instrument tray count in complex arthroplasty cases. Medigear.uk can confirm the technical specification for clinical engineering review.

Trauma teams performing percutaneous fracture fixation, external fixator pin placement, and intramedullary nail preparation benefit from the 1000 rpm operating ceiling, which provides adequate bone-penetrating force while keeping the surgeon fully aware of resistance changes along the guidewire path. The forward-and-reverse function supports wire and bit extraction without releasing the grip. The complete set from Medigear.uk arrives ready for immediate CSSD commissioning.

B2B distributors can include the N Series Cannulate Drill within a trauma power tool catalogue alongside the N Series Bone Drill and oscillating saw. Volume pricing, OEM labelling, and CE and ISO documentation packages are available through the Medigear.uk procurement team.

4.0 mm Centre-Bore Cannula — Guidewire-Constrained Drilling Accuracy

The 4.0 mm hollow cannula of the N Series Cannulate Drill passes the K-wire or guide pin through the centre of the handpiece during drilling, physically constraining the drill bit to the guidewire trajectory and eliminating the angular deviation that occurs when following a guidewire manually with a standard solid-chuck drill. This constraint directly improves the accuracy of intramedullary nail preparation, cannulated screw hole placement, and percutaneous fixation, with the 4.0 mm bore diameter being the accepted standard across the major orthopaedic trauma implant systems.

1000 rpm Controlled Speed Ceiling — Enhanced Tactile Feedback in Guided Technique

The 1000 rpm maximum speed of the N Series Cannulate Drill provides a controlled penetration rate that preserves tactile resistance feedback through the handpiece as the guided drill bit advances along the guidewire path, which allows the surgeon to detect resistance changes indicating approach to the far cortex or any unexpected anatomical variation. This lower-speed ceiling, compared with standard bone drills, is the primary clinical distinction of this variant and is particularly valued by surgeons who prefer a more conservative speed range for the guided cannulated technique. Medigear.uk can confirm the speed specification with the manufacturer's documentation.

Detachable Chuck — One Handpiece, Both Cannulated and Standard Drilling

The detachable chuck converts the N Series Cannulate Drill from a cannulated 4.0 mm guided-wire drill to a standard 0.7 to 6.5 mm keyed chuck drill, allowing the same handpiece to serve both guided and conventional drilling functions within a single operative session without a second powered instrument on the tray. This dual-mode capability reduces the trauma instrument tray count and the sterilisation load between cases.

≤ 0.05 mm Axial Run-Out — Concentricity Precision for Guidewire Technique

The N Series Cannulate Drill maintains axial run-out at or below 0.05 mm, ensuring the drill bit tip remains within 0.05 mm of the intended rotation centre and accurately follows the established guidewire path. This specification is confirmed in the N Series product documentation available through Medigear.uk.

CE Certified and ISO 13485-Aligned — Compliance Ready for Institutional Procurement.

The CE-certified, ISO 13485-aligned manufacturing of the N Series Cannulate Drill meets the compliance requirements of NHS trust procurement committees, hospital medical device approval panels, and government framework buying assessors. Medigear.uk has the Declaration of Conformity ready to issue with the product, enabling procurement teams to complete institutional submissions promptly.

Stepless Variable Speed Trigger — Guidewire Engagement Before Rotation Begins

The full 0 to 1000 rpm range is delivered through a proportional, stepless trigger starting at zero, allowing the surgeon to confirm that the drill bit is concentrically engaged with the guidewire on the cortical surface before any rotation begins. Zero-start prevents wire displacement during initial bit engagement, which is the primary technical requirement of the cannulated drilling technique.

Forward and Reverse Direction Control — Wire Extraction Without Releasing Grip

The integrated direction switch enables forward and reverse rotation without releasing the grip, supporting K-wire withdrawal after provisional fixation, drill bit extraction from the binding bone, and guide pin repositioning during cannulated screw placement.

Autoclavable Handpiece at 135°C — Standard CSSD Reprocessing Integration

The N Series handpiece is autoclavable at up to 135°C once the NiMH battery is removed and integrates directly into standard Class B CSSD reprocessing cycles. The validated sterilisation protocol is available from Medigear.uk for supply to sterile services departments on request.

The UK offers OEM configuration, volume pricing, and custom set composition for the N Series Cannulate Drill, making it a useful guided-drilling platform for B2B distributors building orthopaedic trauma power-tool catalogues. CE and ISO documentation packages are provided by the Medigear.uk business team for distributor regulatory submissions.

Minimum Speed: 0 rpm — Zero-Start for Guidewire Engagement

The N Series Cannulate Drill starts from zero rpm, allowing the drill bit to be positioned over the guidewire on the cortical surface before rotation begins. Zero-start prevents wire displacement at initial bit engagement, which is the primary technique requirement of cannulated drilling.

Maximum Speed: 1000 rpm — Controlled Ceiling for Guided Cannulated Technique

The 1000 rpm maximum speed provides a controlled penetration rate suited to guided cannulated technique, preserving tactile resistance feedback while delivering sufficient cutting force for cortical and cancellous bone. This is the operating speed for this N Series Cannulate Drill variant as supplied by Medigear.uk.

Total Speed Range: 0 to 1000 rpm — Stepless Variable Control

The complete 0 to 1000 rpm range is continuously variable via the trigger, with no stepped transitions, allowing real-time speed modulation as bone density changes along the guided drill path.

Axial Concentricity Run-Out: ≤ 0.05 mm — Precision Maintained

The ≤ 0.05 mm axial run-out is maintained across the full operating speed range in both cannulated and standard chuck modes. This precision is confirmed in the N Series product documentation from Medigear.uk.

Cannula Centre Bore: 4.0 mm — Standard Guidewire Through-Pass

The 4.0 mm centre bore accommodates standard K-wires and guide pins used in intramedullary nail, cannulated screw, and percutaneous K-wire technique. Bore-to-bit axis concentricity is maintained at ≤ 0.05 mm axial run-out.

Detachable Chuck System: 0.7 to 6.5 mm Gripping Range

When attached, the chuck accepts instruments from 0.7 to 6.5 mm for standard drilling. When removed, the handpiece enters pure cannulated mode with the 4.0 mm bore accessible. Reattachment restores the standard keyed-chuck drilling mode.

Direction Control: Forward and Reverse Switch on Handpiece

An integrated direction switch enables forward and reverse rotation without releasing the grip. The switch requires deliberate actuation and is positioned for thumb operation.

Battery: 14.4 V NiMH — Non-Autoclavable, Removed Before Sterilisation
