The S Series Sternum Saw is a variable-speed, battery-powered surgical power tool engineered for median sternotomy — the primary surgical access approach for cardiac, thoracic, and transplant procedures. Its motor delivers a reciprocating frequency of 0 to 14,000 cycles per minute, providing the controlled, fast-cutting performance required to divide the sternum in a single pass cleanly. The ergonomic pistol-grip handpiece is designed for single-handed operative control, reducing surgeon fatigue during the access phase of extended cardiothoracic procedures.

The defining design feature of the S Series Sternum Saw is its 360-degree rotating head, which allows the saw blade to be angled and oriented to the sternal approach without repositioning the handpiece. An integrated blade guard protects the soft tissue of the mediastinum and pericardium from inadvertent blade contact during sternal division, which is the principal soft-tissue risk in median sternotomy. The variable trigger provides proportional speed response throughout the full 0 to 14000 cpm range, giving the surgeon direct control over cutting intensity.

Power is supplied through a 14.4 V nickel-metal hydride battery system. Two batteries are included in the standard set, along with two aseptic battery transfer rings that allow the non-autoclavable batteries to be transferred to the sterile operative field without compromising sterile field integrity. A full charge cycle is completed in approximately two hours on the included charger.

The handpiece body is constructed from stainless steel. It is fully autoclavable at up to 135°C at 1.6 MPa using high-temperature, high-pressure sterilisation, while the battery must be removed and handled separately. The S Series Sternum Saw is CE Certified and aligned with ISO 13485 quality management standards. The complete set includes the handpiece, two batteries, a charger, two aseptic transfer rings, sternum saw blades, and an aluminium case. Full conformity documentation is available through Medigear.uk on request.

Cardiothoracic and cardiac surgery units depend on a sternum saw that delivers fast, clean, and controlled sternal division with minimal soft-tissue trauma to the mediastinum. The S Series Sternum Saw, available through Medigear.uk, provides variable speed from 0 to 14000 cpm and a 360° rotating head with an integrated blade guard, allowing the surgical team to approach the sternum from any angle while protecting the pericardium from blade contact. CE Certification and ISO 13485-aligned documentation support the procurement approval processes of hospital cardiac surgery units, NHS cardiothoracic programmes, and institutional buying groups.

In transplant surgery, where operative time affects donor organ viability, the S Series's battery-powered configuration removes pneumatic setup time, allowing the team to begin sternal access immediately. The variable trigger enables division at the optimal speed for each patient's sternal density, which is especially relevant in repeat sternotomy cases where adhesion patterns require a more careful approach. Medigear.uk supplies the S Series as a dual-battery set to prevent operative interruption during extended cardiothoracic cases.

Thoracic surgical teams performing lung resection, mediastinal tumour excision, and oesophageal procedures via median sternotomy also rely on a saw that can be positioned quickly and oriented precisely. The 360° rotating head of the S Series eliminates the need to reposition the handpiece for different entry angles, reducing operative setup time and physical demands on the surgical team. The complete set from Medigear.uk arrives ready to deploy from goods receipt.

B2B distributors supplying cardiac surgery units and thoracic theatre programmes can position the S Series Sternum Saw as part of a dedicated cardiothoracic power-tool offering. We offer volume pricing, OEM labelling, and CE and ISO documentation packages from the Medigear.uk procurement team for distributors managing their own market regulatory requirements.

360° Rotating Head — Blade Orientation Without Handpiece Repositioning

The 360-degree rotating head of the S Series Sternum Saw is the feature that most directly distinguishes it from fixed-head sternum saws and determines its clinical utility in median sternotomy. By allowing the blade to be oriented at any angle relative to the grip without moving the handpiece, the rotating head provides the surgeon with continuous control over the blade-to-sternum relationship throughout the full length of the sternal cut, regardless of table position or patient anatomy. This reduces the physical awkwardness of the standard sternotomy approach and is particularly valuable in reoperative cases, where prior incisions and adhesions constrain the access geometry.

Integrated Blade Guard — Mediastinal Tissue Protection During Sternal Division

The blade guard integrated into the S Series saw head sits beneath the cutting edge and creates a physical barrier between the blade teeth and the mediastinal contents — the pericardium, cardiac chambers, and great vessels — throughout the sternal division pass. This protection addresses the principal soft-tissue risk of median sternotomy, where the posterior sternal surface may be adherent to pericardial tissue in primary cases and densely scarred in reoperative cases. The blade guard is a standard design feature of the S Series, as confirmed in the product documentation available on Medigear.uk.

0 to 14000 cpm Variable Frequency — Precise Control for Every Sternal Profile

The full 0 to 14000 cpm variable-speed range, delivered via a proportional trigger, gives the surgeon real-time control over cutting intensity from initial cortical engagement through the full thickness of the sternum. Lower frequencies are used when initiating the cut or when approaching known adhesion sites in repeat sternotomy. At the same time, higher frequencies enable efficient division of the sternum's main body in cardiac emergency access cases where speed is critical. This range is consistent with the accepted operating specification for surgical sternum saws used in cardiothoracic surgery.

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

The S Series Sternum Saw's CE Certification and ISO 13485-aligned manufacturing meet the compliance requirements of NHS cardiothoracic unit procurement committees, hospital medical device approval panels, and government buying framework assessors. Medigear.uk holds the Declaration of Conformity and technical documentation ready to issue alongside the product, eliminating the administrative delays that occur when compliance paperwork must be sourced separately from the instrument. This documentation readiness helps cardiac programme managers meet commissioning or tender timelines.

14.4 V NiMH Battery — Environmentally Responsible Energy System

The 14.4 V nickel-metal hydride (NiMH) battery system of the S Series Sternum Saw uses NiMH chemistry, which avoids the thermal-runaway risk associated with lithium-ion batteries in autoclaved surgical environments and is considered more environmentally responsible than cadmium-based alternatives. Two batteries are included in the standard set, providing a battery-switching system in which one charges while the other supports the active procedure, eliminating the risk of power interruption during a median sternotomy sequence. Replacement batteries are available as spare parts through Medigear.uk.

Autoclavable Handpiece at 135°C / 1.6 MPa — Validated CSSD Integration

The S Series handpiece and all metal components are autoclavable at up to 135°C at 1.6 MPa, meeting the validated sterilisation parameters used in hospital CSSD departments for reusable Class B surgical instruments. The battery is removed before sterilisation and transferred to the sterile field using the aseptic transfer ring protocol included with the set, ensuring compliance with infection control without requiring cold-process sterilisation agents or special handling. The validated sterilisation protocol is available from Medigear.uk for supply directly to sterile services departments.

Dual-Battery Set with Aseptic Transfer Rings — Uninterrupted Sterile Field Availability

Two batteries and two aseptic transfer rings are included in every S Series Sternum Saw set, providing a battery-rotation system in which one battery charges while the other powers the handpiece, and ensuring that the sterile field is never compromised during battery changes through the transfer-ring protocol. For cardiac surgery units running sequential operative lists with minimal turnaround time between cases, the two-battery configuration prevents downtime caused by a single exhausted power cell. Medigear.uk supplies both as standard set components, not as separately procured accessories.

Complete Set Configuration — Cardiac Theatre Ready From Goods Receipt

The S Series Sternum Saw is supplied as a complete ready-to-deploy set containing the handpiece, two NiMH batteries, charger, two aseptic battery transfer rings, sternum saw blades, and an aluminium carrying and storage case, allowing the instrument to move from goods receipt through sterile services and into operative use without sourcing additional components. For cardiac theatre procurement managers commissioning a new facility or replacing an end-of-life sternum saw, Medigear.uk supplies the full set as a single line item, including all compliance documentation.

OEM and Volume Supply — Flexible for Distributor and Cardiothoracic Procurement

Medigear. The UK offers the S Series Sternum Saw for OEM configuration, volume pricing, and custom set composition, making it a viable catalogue product for B2B medical equipment distributors serving cardiothoracic and thoracic surgical theatre markets. We can provide white-label branding, packaging, and documentation in different regulatory formats, depending on order volume. The Medigear.uk business team provides the CE and ISO documentation packages needed to support distributor regulatory approval processes in each operating market.

Minimum Speed: 0 cpm — Variable Range From Rest

The S Series Sternum Saw starts from zero cpm at rest, enabling the surgeon to position the saw blade precisely against the sternal surface before any cutting motion begins. This zero-start capability is particularly important in repeat sternotomy, where the blade must be confirmed to be clear of adhesion planes before full-speed cutting commences, and in emergency access cases, where initial blade placement accuracy is critical before increasing speed for rapid sternal division.

Maximum Speed: 14000 cpm — Efficient Sternal Division Ceiling

The 14000 cpm maximum frequency provides the cutting efficiency needed to complete a full median sternotomy in a single controlled pass through the sternum, including through the dense cortical bone of the manubrium at the superior end of the cut. This frequency ceiling is consistent with the established specification for battery-powered sternum saws used in cardiothoracic surgery. It is confirmed in the S Series technical documentation available from Medigear.uk.

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

The complete 0 to 14000 cpm range is continuously variable through the trigger, providing proportional speed response without stepped transitions between pre-set frequency bands. Stepless control allows the surgeon to modulate cutting intensity in real time as the blade passes through the varying bone densities of the manubrium, sternal body, and xiphoid process, and to slow the cutting immediately if the blade approaches an area of anticipated adhesion during a repeat sternotomy.

Motor System: Single Reciprocating Motor, 14.4 V NiMH Drive

The S Series is driven by a single reciprocating motor operating at 14.4 V from the NiMH battery, delivering a consistent blade frequency from 0 to 14000 cpm with stable power output throughout the full operative duration of a standard median sternotomy. The motor is housed within the stainless steel handpiece body and is designed to withstand the sustained mechanical load of cardiothoracic bone cutting. Full output power specification should be confirmed with the Medigear.uk procurement team for institutional review.

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

Two 14.4 V NiMH batteries are included with every S Series Sternum Saw set, supporting a rotation system in which one charges while the other is in use. The batteries are not autoclavable and must be transferred to the sterile field using the two aseptic battery transfer rings included in the set. Replacement batteries are available as spare parts through Medigear.uk for ongoing instrument maintenance.

Aseptic Transfer Rings: 2 Included — Sterile Battery Transfer Protocol

Two aseptic battery transfer rings are supplied as standard components in every S Series set, providing the sterilisable interface required to move a charged battery from a sterile container onto the scrub nurse's instrument table and into the handpiece without compromising sterile field integrity. This protocol is the standard infection-control procedure for battery-powered surgical instruments whose batteries cannot be autoclaved. The reprocessing method for the transfer rings is documented in the user manual available from Medigear.uk.

360° Rotating Head — Full Blade Orientation Without Grip Change

The saw head rotates through a full 360 degrees, allowing the blade to be oriented to any angle relative to the handpiece axis without the surgeon releasing the grip or repositioning the instrument. This rotation range provides continuous intraoperative adjustment as the sternal approach angle changes along the length of the cut and is the principal ergonomic advantage of the S Series design over fixed-head sternum saws.

Integrated Blade Guard — Posterior Sternal Surface Protection

The blade guard integrated into the S Series saw head creates a physical barrier between the cutting teeth and the posterior surface of the sternum during division, protecting the pericardium, cardiac fat, and mediastinal vessels from inadvertent blade contact. The guard is engaged throughout the full sternotomy pass and cannot be accidentally disengaged during operative use. This design element is confirmed as a standard feature of the S Series handpiece.

Handpiece Material: Stainless Steel — Autoclavable at 135°C / 1.6 MPa

The S Series handpiece body is manufactured from high-grade stainless steel, providing corrosion resistance through repeated high-temperature, high-pressure autoclave sterilisation at up to 135°C at 1.6 MPa. Stainless steel construction is the standard material specification for reusable Class II surgical power tools. It supports the instrument's operational lifespan throughout the full sterilisation and use cycle volume of a busy cardiothoracic programme.

Sterilisation: Handpiece Autoclavable at 135°C / 1.6 MPa, Battery Separate

The handpiece and metal components are autoclavable at up to 135°C at 1.6 MPa using high-temperature, high-pressure sterilisation. At the same time, the NiMH battery must be removed and processed separately using the aseptic transfer ring protocol. The validated sterilisation cycle parameters are documented in the user manual and are available from the Medigear.uk team for direct supply to CSSD or sterile services departments on request.

Blade System: Sternum Saw Blades with Blade Guard — Included in Set

The S Series Sternum Saw set includes sternum saw blades and the integrated blade guard as standard components. The blade design is specific to the sternal division and is distinct from the oscillating or reciprocating blade formats used in orthopaedic trauma surgery. Replacement blades are available from Medigear.uk as individual consumables for ongoing set replenishment.

Set Contents: Handpiece, Two Batteries, Charger, Two Transfer Rings, Blades, Aluminium Case

Every S Series Sternum Saw is supplied as a complete, ready-to-deploy set containing all components required from goods receipt through sterile services to operative use. The aluminium case organises and protects components during storage and transit, and individual replacement items, including batteries, transfer rings, and blades, are available from Medigear.uk for instrument maintenance throughout the handpiece's operational lifespan.

FAQ

Frequently Asked Questions

Everything buyers need to know about sourcing medical equipment through MediGear.

A sternum saw is a powered surgical instrument used to divide the sternum — the breastbone — longitudinally along its midline during a procedure called median sternotomy, which provides the primary surgical access route for cardiac operations, including coronary artery bypass grafting, valve repair and replacement, heart transplantation, and aortic root surgery. It is also used for thoracic procedures, including lung resection and mediastinal tumour excision, where central access is required. The saw must cut through hard cortical bone rapidly and cleanly while protecting the mediastinal soft tissues beneath the sternum with an integrated blade guard. Medigear.uk stocks the S Series Sternum Saw for procurement by cardiothoracic surgical programmes, cardiac theatres, and institutional distributors.

The S Series Sternum Saw operates from 0 to 14,000 cycles per minute with continuously variable speed via a proportional trigger. Variable speed is clinically important in sternotomy because patients present with different sternal thicknesses, bone densities, and anatomical configurations, and because repeat sternotomy cases involve adhesion planes between the posterior sternum and the pericardium where slow, controlled blade advancement is necessary to avoid cardiac injury. The ability to begin the cut at low speed and increase once the blade is seated and aligned is a meaningful safety feature in high-risk sternotomy cases. Medigear.uk can provide the technical datasheet confirming the full-speed and torque specifications for institutional clinical review.

The 360-degree rotating head allows the saw blade to be oriented to any angle relative to the handpiece without the surgeon needing to reposition the body or wrist of the instrument. This is particularly useful in sternotomy, where the operative approach angle varies with patient positioning, table height, and the cardiac surgeon's specific technique. Without a rotating head, the surgeon must awkwardly reposition the handpiece to maintain the correct blade-to-sternum angle along the length of the cut, increasing fatigue and reducing precision. The S Series rotating head, combined with the integrated blade guard, provides the control and tissue protection needed for safe, efficient median sternotomy.

The integrated blade guard of the S Series Sternum Saw sits beneath the blade and acts as a barrier between the cutting edge and the posterior surface of the sternum, protecting the pericardium, great vessels, and epicardial fat from inadvertent blade contact during sternal division. This protection is especially critical in primary sternotomy, where the pericardium may be intimately adherent to the posterior sternum, and in repeat sternotomy cases, where scar tissue and adhesions may bring pericardial or cardiac tissue even closer to the cutting line. The blade guard design is confirmed as a standard feature of the S Series Sternum Saw and is documented in the user manual available from Medigear.uk.

The 14.4 V NiMH batteries of the S Series Sternum Saw are not autoclavable and must be removed from the handpiece before high-temperature sterilisation of the instrument. Two aseptic battery transfer rings are included in the standard set: sterilisable sleeves or covers that allow a charged battery to be moved from a sterile container onto the scrub nurse's table and into the handpiece battery compartment while maintaining sterile field integrity throughout the procedure. The handpiece and all metal components are autoclavable at up to 135°C at 1.6 MPa once the battery is removed. Medigear.uk can provide the validated sterilisation protocol for supply to sterile services and CSSD departments on request.

The S Series Sternum Saw is CE Certified and manufactured to ISO 13485 quality standards for medical devices, meeting the compliance requirements of NHS trusts and hospital procurement processes for Class II powered surgical instruments. CE marking confirms that the device has been assessed against the essential requirements of the applicable Medical Device Directive. If you need Declaration of Conformity documents, technical files, or audit-ready documentation packages, our Medigear.uk procurement team can provide them alongside the product to support internal approval submissions and tender documentation.

Yes, the S Series Sternum Saw is suited to repeat sternotomy procedures, where the variable-speed trigger is particularly valuable for managing blade advancement speed through the adhesion planes between the posterior sternum and the pericardium. The integrated blade guard provides the tissue protection needed when the posterior sternal surface may be closely associated with cardiac structures due to previous operative scarring. Surgical teams considering the S Series for repeat sternotomy programmes should contact the Medigear.uk team for technical guidance and to confirm blade compatibility with the specific technique used in their cardiac unit.

Yes, Medigear.uk supports volume procurement and OEM configuration of the S Series Sternum Saw for hospital cardiothoracic programmes, NHS framework agreements, B2B medical equipment distributors, and institutional buying groups. Custom branding, packaging, and set composition options may be available depending on order volume and lead time, and Medigear.uk can supply the complete CE and ISO documentation package needed to support distributors' own regulatory submissions in their operating markets. The Medigear.uk business team can discuss commercial terms and supply chain timelines directly with procurement contacts.

Warranty terms for the S Series Sternum Saw should be confirmed with the Medigear.uk procurement team, as coverage varies by order type and any applicable service agreement. Standard warranty provisions for surgical power tools of this class typically cover manufacturing defects in the handpiece motor and structural components, with batteries and consumable items, including saw blades, warranted separately. Medigear.uk can provide written warranty terms and after-sales support details as part of the procurement documentation package for institutional buyers and cardiothoracic programme directors.

Standard delivery lead times for the S Series Sternum Saw through Medigear.uk are typically 15 to 20 business days from confirmed order for in-stock units, with air and sea freight options available depending on urgency and destination. For larger-volume orders, OEM configurations, or custom set compositions, lead times may be longer due to manufacturing and packing schedules. Cardiothoracic programme managers and procurement officers should contact the Medigear.uk team in advance to obtain a confirmed delivery schedule to include in facility commissioning plans or tender documentation.
