The High Efficiency Surgical Reciprocating Saw for Joint Operations is a versatile orthopedic tool optimized for rapid, precise bone resection in hip, knee, and shoulder surgeries. Its brushless motor delivers 13,500 strokes/min with 3–5mm adjustable stroke length , balancing speed and control to reduce surgical time by 20% compared to conventional saws.

Certified by CE, FDA, and ISO 13485 , this system features a 14.4V lithium-ion battery providing 90+ minutes of runtime and IPX7 waterproof rating for thorough cleaning. Its ergonomic grip (weight: 1.1 kg ) minimizes fatigue during joint replacements, while low-vibration technology (≤3 m/s²) enhances precision in delicate procedures like shoulder arthroplasty.
The 14.4V battery delivers 10+ Nm torque , enabling efficient resection of dense cortical bone in total hip arthroplasty. A variable stroke length (3–5mm) adapts to tissue type: 3mm for osteoporotic bone to prevent over-cutting, 5mm for rapid resection in revision surgeries.
±0.01mm blade alignment ensures accurate bone contouring, critical for implant fitting in knee replacement where 1mm misalignment can cause joint instability. Automatic torque limiting at 19 Nm prevents sudden breakthrough, while a blade guard retracts during bone contact and extends to protect soft tissues during retraction.
The tool-free blade release supports Stryker, Zimmer Biomet, and Smith & Nephew blades (6–18mm width), covering applications from small bone resection (6mm blade) to femoral head removal (18mm blade). The integrated Jacobs chuck (2–8mm) accommodates drill bits, streamlining workflows in combined drilling and sawing procedures.
The rubberized grip and balanced weight distribution reduce wrist strain during 2+ hour surgeries, while the low-vibration motor minimizes hand fatigue—key for maintaining precision in acetabular reaming or tibial plateau resection.
Thermal cutoff sensors pause operation if internal temperature exceeds 60°C , preventing tissue burns. A blade lock mechanism secures attachments during sterilization, and low-battery alerts (audible and visual) activate at 15% charge to prevent intraoperative shutdowns.
Hip and Knee Arthroplasty: Resects femoral and tibial bone for implant fitting, with adjustable stroke length optimizing performance for dense or osteoporotic bone.
Shoulder Surgery: Enables precise acromionectomy and humeral head resection, supporting rotator cuff repair and total shoulder replacement.
Orthopedic Oncology: Removes tumor margins with ±0.5mm accuracy , minimizing healthy tissue loss and reducing recurrence risks.
Trauma Surgery: Facilitates rapid fracture stabilization in mobile units, with cordless design enhancing mobility in emergency settings.
Q: Can the saw be used for arthroscopic procedures?
A: Yes, it includes a 5mm arthroscopic adapter for minimally invasive joint surgeries, enabling bone resection through small incisions.
Q: What is the maximum blade depth?
A: The saw supports up to 18mm depth , suitable for most joint and trauma applications, including femoral canal preparation and acetabular reaming.
Q: Is the battery compatible with third-party chargers?
A: Yes, it works with 14.4V lithium-ion chargers from Stryker, Conmed, and other leading brands, ensuring flexibility in multi-vendor ORs.
Q: How is the blade sharpness maintained?
A: The diamond-like carbon (DLC) coating reduces friction and wear, ensuring sharpness for 50+ procedures —doubling the lifespan of uncoated blades.
