Key Features & Types
Types of Saws:
Oscillating Saws: Blades move in a small arc for controlled cuts, minimizing soft tissue damage. Commonly used in joint replacements THR,TKA…(e.g., knee or hip).
Reciprocating Saws: Blades move back-and-forth for cutting thicker bones. Commonly used in UKA,Maxillofacial…(e.g., during amputations or spinal surgeries).
Sagittal Saws: A subtype of oscillating saws, often used in craniotomies or sternotomies.
TPLO Saws: TPLO saws are critical for achieving the precision required in tibial plateau leveling osteotomies. Their specialized design ensures safe, efficient bone cutting, directly impacting the success of CCL repair in veterinary orthopedics.
Design & Materials:
Materials: High-grade stainless steel, titanium, or diamond-coated edges for durability and sharpness.
Tooth Configuration:
Fine teeth for delicate cuts (e.g., small bones or pediatric surgery).
Coarser teeth for rapid cutting in dense bone.
Sterilization Compatibility: Designed to withstand repeated autoclaving (reusable) or single-use disposables.
Safety & Precision:
Guards/Guides: Prevent over-penetration and protect surrounding tissues.
Low Heat Generation: Minimizes thermal necrosis (e.g., through irrigation channels or advanced blade coatings).
Ergonomics: Reduced vibration for surgeon comfort and control.
Applications
Common Procedures: Joint replacements (knee, hip), fracture repairs, spinal surgeries, and amputations.
Specialized Blades:
Microsurgical Blades: For minimally invasive or pediatric cases.
Sternotomy Blades: Used in cardiac surgeries to split the sternum.
Innovations & Considerations
Single-Use vs. Reusable:
Single-use blades reduce infection risk but increase costs.
Reusable blades require stringent sterilization protocols.
Advanced Coatings: Diamond or ceramic coatings enhance longevity and cutting efficiency.
Regulatory Compliance: Must meet FDA/ISO standards for safety and efficacy.
Leading Manufacturers
Bojin,Stryker, Zimmer Biomet, DePuy Synthes, and Medtronic are key producers of these specialized tools.
Noted: Different manufacturers provide different types of couplings.
