XC N-Series Sternum Saw

Cardiothoracic surgery theatres performing primary median sternotomy for cardiac bypass, valve repair, and similar procedures require a sternum saw that delivers controlled sternal division with integrated mediastinal protection. The N Series Sternum Saw, available through Medigear.uk, provides 0 to 14000 cpm variable frequency through a standard motor combined with a sternum guard that shields anterior pericardial and vascular structures from blade contact during sternotomy. CE Certification and ISO 13485-aligned documentation support the institutional approval requirements of hospital cardiac surgery programmes and NHS procurement frameworks.

In repeat sternotomy — where adhesions between the sternum and anterior mediastinal structures increase the chance of cardiac injury during sternal re-entry — the sternum guard is critical. The stepless variable trigger allows the surgeon to reduce speed at any point of elevated mediastinal risk, and the quick-lock blade system enables rapid blade changes if a different blade profile is required during the re-entry. Medigear.uk can confirm the sternum guard mechanism and blade compatibility from the N Series technical documentation.

Thoracic surgery teams requiring sternal access for mediastinal tumour resection, pericardial procedures, and other cardiothoracic operations benefit from the N Series Sternum Saw's controlled 14000 cpm ceiling, which provides sufficient cutting efficiency for full sternotomy while keeping the surgical team in control of the blade at all times. The complete set from Medigear.uk arrives ready for immediate CSSD commissioning.

B2B distributors building cardiac and cardiothoracic surgery power tool catalogues can position the N Series Sternum Saw alongside oscillating saws, reciprocating saws, and bone drills. Volume pricing, OEM labelling, and CE and ISO documentation packages are available through the Medigear.uk procurement team.

Sternum Guard — Mediastinal Soft Tissue Protection Throughout Sternal Division

The sternum guard is a blade-mounted protective component that interposes a physical barrier between the saw blade and the anterior mediastinal structures — pericardium, ascending aorta, and right ventricular outflow tract — throughout the full length of the sternotomy. This protection is the defining patient-safety feature of a sternum saw compared with a standard reciprocating saw used without a guard, and is of particular clinical importance during repeat sternotomy, in which mediastinal adhesions bring these structures into proximity with the posterior sternal table. The sternum guard mechanism is confirmed as a standard component of the N Series Sternum Saw, with documentation available from Medigear.uk.

0 to 14000 cpm Stepless Variable Frequency — Real-Time Speed Control for Every Sternotomy Risk Level

The full 0 to 14000 cpm range is delivered via a proportional, stepless trigger, allowing the cardiac surgeon to modulate cutting frequency in real time as sternal density, proximity to the posterior cortex, and anatomical risk level change throughout the sternotomy. This control is especially important during repeat sternotomy, where the surgeon must be able to reduce frequency instantly when increased resistance signals proximity to an adhered structure.

Toolless Quick-Lock Blade Interface — Rapid Blade Changes Intraoperatively

The quick-lock blade mechanism allows intraoperative blade changes without tools, enabling the scrub nurse to swap between sternum saw blade formats in seconds when required during a complex sternotomy. This speed reduces the time required for blade changes in an open cardiac field. Replacement sternum saw blades are available through Medigear.uk.

CE Certified and ISO 13485-Aligned — NHS-Ready for Cardiac Theatre Procurement.

The N Series Sternum Saw is CE-certified and manufactured in accordance with ISO 13485, meeting the compliance requirements of NHS trust cardiothoracic programme procurement committees and hospital medical device approval panels. Medigear.uk holds the Declaration of Conformity and technical documentation ready to issue alongside the product, reducing the administrative preparation time for clinical governance submissions in cardiac surgery departments.

Autoclavable Handpiece at 135°C — Validated for Cardiac CSSD Reprocessing

The N Series 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 cardiac hospital sterile services. The validated sterilisation protocol is available from Medigear.uk for supply to sterile services departments and cardiac theatre managers.

≥ 20 W Output Power — Sustained Cutting Efficiency Under Sternal Load

The minimum output power of 20 W ensures the N Series Sternum Saw maintains its rated frequency under the resistive load of the sternal cortex and the denser areas of the anterior sternal body, preventing blade-speed loss during the operative approach to the posterior cortex.

Stainless Steel Construction — Long-Life Autoclavable Cardiac Instrument

The N Series Sternum Saw handpiece is manufactured from high-strength stainless steel that maintains structural integrity and corrosion resistance during repeated autoclave sterilisation at 135°C, supporting the instrument's operational lifespan under the daily sterilisation demands of a busy hospital cardiac programme.

Complete Set in Aluminium Case — Theatre Ready From Goods Receipt

The N Series Sternum Saw is supplied as a complete set in an aluminium alloy case containing all standard components. Individual replacement items, including batteries and sternum saw blades, are available through Medigear.uk for ongoing instrument maintenance.

OEM and Volume Supply — Sternum Saw Platform for Cardiac Distributor Catalogues

Minimum Speed: 0 cpm — Zero-Start for Controlled Initial Sternal Engagement

The N Series Sternum Saw starts at zero cpm, allowing the blade to be positioned against the sternal surface and the sternum guard to be positioned correctly before any blade motion begins. Zero-start prevents inadvertent saw motion during blade placement, the primary safety requirement for cardiac surgery power tools.

Maximum Speed: 14000 cpm — Standard Ceiling for Sternal Division

The 14000 cpm maximum frequency provides sufficient cutting efficiency for primary sternal division in a single controlled pass. This is the confirmed operating speed for the N Series Sternum Saw.

Total Speed Range: 0 to 14000 cpm — Stepless Variable Control

The complete 0 to 14000 cpm range is continuously variable through the trigger without stepped transitions, allowing the cardiac surgeon to modulate cutting intensity in real time throughout the sternotomy.

Sternum Guard: Integrated Blade Guard — Mediastinal Soft Tissue Protection

The sternum guard is a standard component of the N Series Sternum Saw blade assembly that interposes a protective surface between the saw blade and anterior mediastinal structures during sternal division. It cannot be removed during use and applies throughout the full length of the sternotomy.

Output Power: ≥ 20 W — Sustained Performance Under Cortical Sternal Load

A minimum output power of 20 W ensures the N Series Sternum Saw maintains its rated frequency under the resistance of the sternal cortex. This specification is confirmed in the N Series technical data sheet.

Temperature Rise: ≤ 25°C — Comfortable Cardiac Theatre Handpiece Operation

The motor and handpiece temperature rise during operation is maintained at or below 25°C above ambient, ensuring the handpiece remains comfortable to hold through extended cardiac surgery lists.

Blade Interface: Quick-Lock, Toolless — Sternum Saw Blades

The quick-lock blade interface connects and disconnects sternum saw blades without tools. Sternum saw blades are included in the standard set, and replacement blades are available through Medigear.uk.
