Roundfin RD-SAW-19

Forensic pathology and medicolegal investigation departments are the primary setting for the Roundfin RD-SAW-19 Autopsy Saw. Post-mortem examination requires precise, controlled cutting through bone and tissue with minimal disruption to adjacent structures. The 0–18,000 rpm oscillation range — adjustable across the full speed range — supports accurate cuts in cranial, thoracic, and skeletal autopsy procedures. The absence of tissue splashing during use is significant in forensic settings where specimen integrity affects the evidentiary value of examination findings. Medigear.uk supplies the RD-SAW-19 to forensic pathology departments and can provide CE documentation for procurement review.

Hospital surgical departments and operating theatre teams represent a further application for the RD-SAW-19. AC/DC dual-power compatibility allows operation from the mains supply in a theatre or from battery power in mobile surgical settings, without requiring separate instruments. The low-temperature motor prevents thermal damage to surrounding tissue during cutting — a clinically meaningful feature where thermal injury to adjacent structures is a concern. Medigear.uk can advise on theatre-compatible power configurations and blade specifications on request.

University anatomy departments and medical college pathology teaching programmes benefit from the RD-SAW-19's simple and safe operation, which reduces the learning curve for student users in supervised teaching autopsy contexts. The lightweight construction reduces fatigue during repeated demonstrations, and the no-splashing action maintains a cleaner teaching environment. Stainless steel blades can be sterilised between cadavers in line with standard infection control protocols. Medigear.uk can discuss bulk supply for anatomy departments and forensic training facilities.

Public security authorities, quarantine bureaus, and veterinary pathology operations that require a portable oscillating saw for field autopsies or inspections will find the RD-SAW-19 well-suited for mobile deployment. The 86.4 Wh battery capacity and lightweight design support use outside fixed laboratory settings. Medigear.uk provides procurement guidance and post-purchase support across all channels.

Low-Temperature Motor — No Burns During Extended Use

The RD-SAW-19 motor is specified to operate at low temperatures and not cause burns, which is a meaningful safety feature for a handheld instrument used continuously throughout a full autopsy session. Motor heat transmitted through the tool body can cause operator discomfort or injury during extended use. In procedures where the saw contacts tissue, motor-generated heat could also affect adjacent tissue in sensitive forensic or surgical contexts. The low-temperature motor specification addresses both operator and specimen protection requirements.

No Tissue Splashing During Cutting

The oscillating cutting action of the RD-SAW-19 is specified as producing no splashing during use. In forensic and medicolegal pathology settings, splashing during bone or tissue cutting poses both a contamination risk and a biohazard exposure risk to the operator and other personnel in the examination room. The no-splashing characteristic reduces the need for additional splash-barrier protection, simplifies room decontamination after examination, and supports a safer working environment for anatomy teaching and supervised student use.

No Cartilage Damage During Cutting

The RD-SAW-19 is specified as causing no damage to cartilage tissue during cutting. This is a clinically important distinction from rotary or reciprocating saws that can fragment or crush cartilaginous structures adjacent to the primary cut. In forensic post-mortem examination, intact rib, tracheal, and joint cartilage are often relevant to cause-of-death determination and injury assessment, and preserving these structures during the opening of the thoracic and cranial cavities is a practical advantage for the quality of forensic findings.

AC/DC Dual Power for Fixed and Mobile Deployment

The 100V–240V AC input range covers international mains standards, allowing the RD-SAW-19 to be used from fixed laboratory, theatre, or mortuary power supplies without voltage conversion. DC operation from the 86.4Wh onboard battery, with a four-hour charge cycle, supports field autopsy, quarantine inspection, and mobile veterinary pathology deployment where mains supply is unavailable. This dual-mode power system eliminates the need to maintain separate instruments for fixed and mobile use contexts, reducing equipment inventory and training requirements.

0–18,000 rpm Variable Oscillation Speed

The full 0–18,000 rpm oscillation range, adjustable across all speeds, gives operators precise control over cutting speed to match different tissue types and procedure requirements. Lower speeds allow controlled, careful cutting in sensitive anatomical areas, while maximum speed supports rapid progress through dense bone in standard cranial and thoracic opening procedures. This variable-speed range makes the RD-SAW-19 a versatile single instrument for the cuts required in a full post-mortem examination.

High-Quality Stainless Steel Blades with Exceptional Durability

The saw blades are fabricated from high-quality stainless steel, which the Roundfin specification describes as very durable. Stainless steel blade stock maintains cutting-edge integrity across many uses, resists corrosion that would otherwise result from repeated sterilisation and cleaning cycles, and meets the hygiene standards required for forensic and surgical instrument use. The chucking mechanism is rated at M 100N, providing secure blade retention under the loads generated at maximum oscillation speed. Medigear.uk can confirm available blade sizes and types compatible with the RD-SAW-19.

CE Certified for NHS and Institutional Procurement

CE certification is confirmed for the RD-SAW-19. This certification meets the baseline conformity requirements for medical and forensic instruments in NHS procurement frameworks and equivalent institutional purchasing processes. Medigear.uk holds the certification documentation and can provide it to procurement officers at the due diligence stage without delay. Institutional buyers procuring the RD-SAW-19 for forensic pathology, anatomy, or surgical use can request the documentation as part of their standard medical device procurement process.

Lightweight and Simple Operation for All Experience Levels

The RD-SAW-19 is designed to be simple and convenient to operate, with the Roundfin specification confirming it is safe and lightweight. The lightweight construction reduces operator fatigue during the extended sessions typical of full post-mortem examinations, and the simple operation supports safe use by less experienced operators in supervised anatomy teaching and forensic training environments. Medigear.uk can supply the RD-SAW-19 to anatomy training providers and forensic education facilities with full application documentation.

Strong Cutting Force on Hard and Plastic Substances

The RD-SAW-19 is specified as capable of cutting very fast with high cutting force on hard, plastic materials. This performance characteristic is relevant in autopsy procedures where cuts must be made through calcified bone, dense connective tissue, or preserved cadaveric material that may have increased resistance compared to fresh tissue. The combination of high oscillation speed, secure blade chucking, and strong cutting force ensures efficient progress through the range of material densities encountered in forensic and anatomy autopsy work.

Voltage: 12V with 120W Output Power

The RD-SAW-19 operates at 12V with 120W output power. The 120W output provides the cutting force necessary for efficient bone and dense tissue cutting at the full 18,000 rpm oscillation speed. The 12V operating voltage is standard for this class of battery-powered oscillating surgical and autopsy instruments.

Oscillation Speed: 0–18,000 rpm

The oscillation speed is continuously adjustable from 0 to 18,000 rpm, covering the full range from slow, controlled start-up speed to maximum cutting velocity. This variable-speed range allows a single instrument to be used across different phases of an autopsy without blade changes. Medigear.uk can confirm the specification of the speed control mechanism upon request.

Oscillation Angle: 4°

The 4° oscillation angle is the standard specification for autopsy and orthopaedic oscillating saws. It provides a controlled cutting arc that minimises lateral blade movement and reduces the risk of unintended tissue damage adjacent to the primary cut. This angle is calibrated for bone cutting applications where precision and control are more important than wide material removal.

Chucking Power: M 100N

The chucking mechanism is rated at M 100N, confirming secure blade retention under the operational loads generated during cutting. This rating prevents blade slippage or detachment during use, which is a safety-critical requirement for a bone-cutting instrument. Medigear.uk can confirm compatible blade specifications and attachment types for the RD-SAW-19.

Input Voltage: 100V–240V AC

The 100V–240V AC input range is compatible with mains standards across international markets — covering 110V North American, 220V European, and 240V UK and Australian supplies — without requiring a voltage converter. This makes the RD-SAW-19 deployable internationally on standard mains power without additional power-supply equipment.

DC Output Voltage: 10V–12V

The DC output voltage range of 10V–12V covers the full operating range of the 12V motor as the battery discharges, ensuring consistent cutting performance across the battery charge cycle rather than only at full charge. This consistent output across the voltage range is relevant for extended-use sessions in which the battery may not be fully charged at the start of a procedure.

Battery Capacity: 86.4Wh with 4-Hour Charge

The 86.4Wh battery capacity provides a meaningful reserve of operating energy for field deployment, supporting extended autopsy or inspection sessions without a mains supply. The four-hour charging time from a standard charger is consistent with overnight or between-session charging in laboratory and field deployment contexts.

Low-Temperature Motor — No Burn Risk

The motor is specified to operate at low temperatures with no burn risk during use. This safety characteristic is essential for a handheld instrument held continuously during cutting and reduces the risk of thermal injury to the operator or heat transfer to adjacent tissue.

No Tissue Splashing

The oscillating cutting action produces no splashing during use. This characteristic reduces the risk of biohazard exposure during bone and tissue cutting procedures, simplifies decontamination of the examination room after use, and supports a safer operating environment for both operator and bystander personnel.

No Cartilage Tissue Damage

The RD-SAW-19 is specified as causing no damage to cartilage tissue during cutting. This preserves cartilaginous structures adjacent to the cut path, which is relevant in forensic post-mortem procedures where intact rib, tracheal, and joint cartilage contribute to cause-of-death and injury assessment.

High-Quality Stainless Steel Blades

Saw blades are fabricated from high-quality stainless steel and are described as highly durable. Stainless steel resists the corrosion caused by repeated cleaning and sterilisation cycles, maintains cutting-edge integrity across multiple uses, and meets medical and forensic instrument hygiene standards.

AC/DC Power Compatibility

Full AC/DC dual-power compatibility allows the RD-SAW-19 to operate from the mains supply (100V–240V) or the onboard battery, making it a single instrument for both fixed laboratory and mobile field deployments without power-supply modification.

CE Certification

CE certification is confirmed for the RD-SAW-19, covering product safety and conformity standards applicable to medical and forensic autopsy instruments. Medigear.uk holds documentation on file and can provide it to procurement and compliance teams on request.
