XC E-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, straight-line sternal division with integrated mediastinal protection. The E Series Sternum Saw, available through Medigear.uk, provides 0 to 14000 cpm variable frequency through a brushless 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 — among the highest-risk sternotomy approaches, 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 brushless motor's consistent frequency under varying sternal density and scar tissue resistance provides controlled cutting throughout the re-entry, and the stepless variable trigger allows the surgeon to reduce speed at any point of elevated risk. Medigear.uk can confirm that the sternum guard mechanism and blade are compatible with the full specification documentation.

Thoracic surgery teams requiring sternal access for mediastinal tumour resection, pericardial procedures, and other cardiothoracic operations benefit from the E Series Sternum Saw's dual-battery set, which ensures operative continuity during long thoracic lists without mid-procedure battery depletion. The aseptic transfer rings allow battery rotation to the sterile field in a controlled infection-control protocol without interrupting operative flow. The complete set from Medigear.uk arrives configured for immediate CSSD commissioning.

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

Sternum Guard — Mediastinal Soft Tissue Protection During 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 E Series Sternum Saw and can be reviewed in the technical documentation available from Medigear.uk.

Brushless Motor — Consistent Sternal Division Across High-Frequency Autoclave Programmes

The brushless motor of the E Series Sternum Saw eliminates carbon brush wear, maintaining consistent cutting frequency and power output over significantly more autoclave sterilisation cycles than a brushed-motor equivalent. For cardiac surgery programmes where the sternum saw is autoclaved between cases on a busy operating list, this translates into a longer instrument service life and a lower total cost of ownership. The brushless motor also produces lower operational noise and less internal heat, contributing to a better theatre environment during long cardiac lists.

Aseptic Battery Transfer Rings — Sterile Battery Protocol as Standard

Two aseptic battery transfer rings are included as standard set components in every E Series Sternum Saw, providing the sterilisable interface needed to transfer a charged battery to the scrub nurse's cardiac theatre instrument table without compromising the sterile field established for open-chest surgery. The inclusion of two rings means both batteries in the dual-battery set can be managed simultaneously under the aseptic transfer protocol, supporting seamless battery rotation across consecutive cardiac cases. Medigear.uk supplies these rings as a fixed set component.

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

The full 0 to 14000 cpm range, delivered through a proportional, stepless trigger, gives the cardiac surgeon precise real-time control over cutting frequency at every stage of the sternotomy — from the initial anterior cortex engagement through the cancellous diploe to the delicate approach to the posterior cortex adjacent to mediastinal structures. 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 adhesed structure. The 14000 cpm ceiling provides the cutting efficiency needed for efficient sternal division in primary sternotomy.

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

The E Series Sternum Saw's CE Certification and ISO 13485-aligned manufacturing meet the compliance requirements of NHS trust cardiothoracic programme 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, reducing the administrative preparation time for clinical governance submissions in cardiac surgery departments.

Dual-Battery Set — Operative Continuity Across Back-to-Back Cardiac Cases

Two batteries are included in every E Series Sternum Saw set, providing a dual-battery system in which one charges while the other powers the handpiece, eliminating the operative delay caused by a single-battery instrument running low on a long cardiac list. When combined with the aseptic transfer ring protocol, this dual-battery system supports continuous sterile battery management throughout an entire cardiac operating programme without interruption or compromise of the sterile field.

Toolless Quick-Lock Blade Interface — Blade Changes Without Instruments

The quick-lock blade mechanism allows intraoperative blade changes without a tool, enabling the scrub nurse to swap between sternum saw blade formats in seconds when required during a complex sternotomy or mediastinal access procedure. This speed reduces the time and infection-control risk associated with blade changes in an open cardiac field. It allows the surgical team to adapt blade geometry within the same operative exposure. Replacement sternum saw blades are available through Medigear.uk.

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

The E 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.

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

Medigear. The UK offers the E Series Sternum Saw for OEM configuration, volume pricing, and custom set composition, making it a premium cardiac surgery catalogue product for B2B distributors building surgical power tool ranges for cardiothoracic theatre markets. We can provide white-label branding and regulatory documentation in different market formats, depending on order volume.

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

The E 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. This zero-start prevents inadvertent saw motion during blade placement, which is a primary safety requirement for cardiac surgery power tools.

Maximum Speed: 14000 cpm — Standard Ceiling for Sternal Division

The 14000 cpm maximum frequency is the established ceiling for sternum saws used in cardiac median sternotomy and repeat sternotomy, providing sufficient cutting efficiency for primary sternal division in a single controlled pass. This ceiling is confirmed as the class specification for the E Series Sternum Saw.

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

The complete 0 to 14000 cpm range is continuously variable via the trigger, without stepped transitions, allowing the cardiac surgeon to modulate cutting intensity in real time as sternal density, proximity to the posterior cortex, and anatomical risk level change throughout the sternotomy.

Sternum Guard: Integrated Blade Guard — Mediastinal Soft Tissue Protection

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

Motor Type: Brushless — Extended Autoclave Lifespan for Cardiac Programmes

The brushless motor eliminates carbon brush wear, providing more consistent frequency output over more sterilisation cycles than brushed designs. Lower operational noise and less internal heat are secondary benefits. The brushless motor is the primary distinction between the E Series and S Series Sternum Saws, both available from Medigear.uk.

Aseptic Battery Transfer Rings: 2 Included — Standard Cardiac Sterile Field Protocol

Two aseptic battery transfer rings are included as standard in every E Series Sternum Saw set, providing the sterilisable interface for both batteries simultaneously. The rings enable the aseptic transfer protocol required to bring a non-autoclavable battery into the cardiac surgical sterile field.

Battery: 14.4 V NiMH — Two Included, Non-Autoclavable

Two 14.4 V NiMH batteries are included, supporting battery rotation during consecutive cardiac cases. The batteries are non-autoclavable and require the aseptic transfer-ring protocol for sterile-field delivery. Replacement batteries are available through Medigear.uk.

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

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

Handpiece Material: Stainless Steel — Autoclavable at 135°C

The handpiece is manufactured from stainless steel and 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 in cardiac and cardiothoracic theatre settings.

Sterilisation: Handpiece Autoclavable at 135°C, Battery via Aseptic Transfer

The handpiece is autoclavable at up to 135°C once the battery is removed. The battery is transferred to the cardiac sterile field using the aseptic transfer ring protocol. The validated protocol is documented in the user manual and available from Medigear.uk for CSSD departments.
