XC N-Series Cannulate Drill with Detachable Drill Chuck

General orthopaedic trauma theatres use cannulated drills for K-wire guided fixation in fracture repair, intramedullary nail preparation, and cannulated screw placement, where drilling accuracy along a pre-positioned guidewire is critical for implant positioning and long-term fixation stability. The N Series Cannulate Drill, available through Medigear.uk, provides variable speed from 0 to 1200 rpm and a 4.0 mm hollow cannula that constrains the drill path to the guidewire trajectory. 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 guided pin placement and cannulated fixation, the N Series Cannulate Drill's ≤ 0.05 mm axial run-out ensures the drill bit follows the guidewire path accurately through the full depth of the bone channel, directly influencing the accuracy of implant seating. The detachable chuck allows the same handpiece to switch to conventional cortical drilling between cannulated steps, reducing the tray instrument count during complex arthroplasty cases. Medigear.uk can provide the full technical specification, confirming run-out and speed, for institutional review.

Trauma teams performing external fixator pin placement, percutaneous K-wire fixation, and guide pin drilling for intramedullary nails benefit from the N Series Cannulate Drill's chuck range of 0.7 to 6.5 mm, covering all standard instrument diameters in this class without requiring a secondary handpiece. The forward-and-reverse function supports wire and bit extraction without releasing the grip. The complete set from Medigear.uk arrives ready for immediate commissioning of sterile services.

B2B distributors can position the N Series Cannulate Drill as a guided-drilling platform in a trauma power-tool catalogue, alongside the N Series Bone Drill. 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, which in turn improves the final implant position and the long-term stability of the fixation construct. The 4.0 mm bore is the accepted standard across the major orthopaedic trauma implant systems for cannulated drilling.

Detachable Chuck — One Handpiece for Both Cannulated and Standard Drilling

The detachable chuck of the N Series Cannulate Drill converts the instrument 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. This dual-mode capability reduces the powered instrument count on the trauma tray and the sterilisation load between cases, both of which are practical operational benefits for theatre managers running high-volume trauma lists. Chuck attachment and removal is a quick mechanical action requiring no tools, enabling the scrub nurse to switch modes during the procedure.

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

The N Series Cannulate Drill maintains axial concentricity run-out at or below 0.05 mm, ensuring the drill bit tip remains within 0.05 mm of the intended rotational axis and accurately follows the established guidewire path through the full operative depth. This concentricity is the standard expected for surgical cannulated drills used in orthopaedic implant placement and is confirmed in the product documentation available through Medigear.uk.

CE Certified and ISO 13485-Aligned — Compliance Ready for Trauma Theatre Procurement

The N Series Cannulate Drill's CE Certification and ISO 13485-aligned manufacturing meet the compliance baseline required by NHS trust procurement committees, hospital medical device approval panels, and government framework buying assessors. Medigear.uk holds the Declaration of Conformity and technical documentation ready to issue alongside the product, enabling procurement teams to complete institutional approval submissions promptly. For multi-instrument N Series procurement, the Medigear.uk team can consolidate compliance documentation across all products.

0 to 1200 rpm Stepless Variable Speed — Guidewire Engagement Before Rotation Begins

The full 0 to 1200 rpm range is delivered through a proportional, stepless trigger starting from zero, allowing the drill bit to be positioned over the guidewire on the cortical surface before any rotation begins. This zero-start is a fundamental requirement for accurate cannulated technique, where the bit must be confirmed concentrically engaged over the guidewire before drilling commences to prevent the initial rotation from displacing the wire from its planned position.

Low Noise at ≤ 63 dB — Consistent with Extended Trauma List Use

The N Series Cannulate Drill operates at or below 63 dB, within the ambient acoustic range of a standard orthopaedic trauma theatre. This noise level is below the threshold requiring supplementary hearing protection for theatre teams and reduces cumulative auditory fatigue during extended trauma lists with multiple cannulated drilling sequences.

Autoclavable Handpiece at 135°C — Integrated Into Standard CSSD Workflows

The N Series Cannulate Drill handpiece is autoclavable at up to 135°C using high-temperature, high-pressure sterilisation once the NiMH battery is removed, integrating directly into standard Class B CSSD reprocessing cycles used in hospital sterile services. The sterilising channel included in the set supports full internal bore sterilisation. The validated sterilisation protocol is available from Medigear.uk for supply to sterile services departments on request.

Forward and Reverse Direction Control — Wire and Bit Extraction Without Releasing Grip

The integrated direction switch enables forward and reverse rotation without releasing the grip, which is particularly useful during cannulated drilling for K-wire extraction after provisional fixation and for drill bit withdrawal from binding bone. The switch requires deliberate actuation and is positioned for thumb operation from the standard pistol grip.

OEM and Volume Supply — Guided Drilling Platform for Distributor Trauma Catalogues

The N Series Cannulate Drill is available for OEM configuration, volume pricing, and custom set composition through Medigear.uk, making it a useful product for B2B distributors building orthopaedic trauma power tool catalogues. White-label branding and regulatory documentation formats may be available depending on order volume. The Medigear.uk business team provides CE and ISO documentation packages needed 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 during initial bit engagement, which is the primary technical requirement of the cannulated drilling technique.

Maximum Speed: 1200 rpm — Standard for Orthopaedic Cannulate Drilling

The 1200 rpm maximum operating speed is the established standard for cannulate drills used in domestic and international orthopaedic trauma practice, providing sufficient rotational force for cortical bone penetration while remaining within acceptable thermal generation limits for standard technique.

Total Speed Range: 0 to 1200 rpm — Stepless Variable Control

The complete 0 to 1200 rpm range is continuously variable via the trigger, with no stepped transitions. Stepless control allows the surgeon to modulate drilling speed in real time as bone density changes through the drill path.

Cannula Centre Bore: 4.0 mm — 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 fixation. The bore concentricity relative to the drill bit axis is maintained at ≤ 0.05 mm axial run-out, which determines how accurately the drill follows the guidewire during bone penetration.

Detachable Chuck System: 0.7 to 6.5 mm Gripping Range

The detachable chuck accepts instruments with shaft diameters from 0.7 to 6.5 mm, including K-wires, standard drill bits, and guide pin adapters. When removed, the handpiece operates in pure cannulated mode with the 4.0 mm bore accessible. Reattachment converts the handpiece to standard keyed-chuck drilling mode.

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 mode. This precision is the accepted standard for surgical cannulated drills and is confirmed in the N Series product documentation from Medigear.uk.

Noise Level: ≤ 63 dB — Below Supplementary Hearing Protection Threshold

The N Series Cannulate Drill operates at or below 63 dB, within the acoustic range of a standard orthopaedic theatre environment. Low noise reduces cumulative auditory fatigue during extended cannulated drilling sequences.

Temperature Rise: ≤ 25°C — Comfortable Extended-Use Handpiece

The motor and handpiece temperature rise during sustained operation is maintained at or below 25°C above ambient. This specification ensures the handpiece remains comfortable to hold during extended trauma drilling sequences.

Direction Control: Forward and Reverse Switch on Handpiece

An integrated direction switch enables forward and reverse rotation without releasing the grip. The reverse is used for wire extraction, bit withdrawal, and screw repositioning. The switch requires deliberate actuation and is positioned for thumb operation.

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

The 14.4 V NiMH battery must be removed before autoclave sterilisation. Replacement batteries are available through Medigear.uk.

Handpiece Material: High-Strength Biomedical Stainless Steel — Autoclavable at 135°C

The handpiece is manufactured from high-strength biomedical stainless steel that is autoclavable at up to 135°C once the battery is removed. Stainless steel construction is the standard for reusable Class II surgical power tools.

Set Contents: Handpiece, Battery, Charger, Detachable Chuck, Sterilising Channel, Aluminium Case

The complete N Series Cannulate Drill set is supplied in an aluminium alloy case containing all components required for immediate clinical deployment. Replacement items, including batteries, sterilising channels, and chuck accessories, are available through Medigear.uk.
