   • Performing osteotomies (bone cutting) for correcting deformities.
   
   
   • Removing bone tumors or fragments in trauma cases.
   
   
   
   


2. Cranial Surgery
   
   
   
   • Circular bone saws are used to create openings in the skull for neurosurgical access.
   
   
   
   


3. Amputations
   
   
   
   • Gigli saws or reciprocating saws are often used to perform amputations efficiently and cleanly.
   
   
   
   


4. Dental and Maxillofacial Surgery
   
   
   
   • Bone saws are used to cut through the jawbone or other hard tissues during reconstructive or corrective procedures.
   
   
   
   


5. Veterinary Surgery
   
   
   
   • Bone saws are also used in animal surgeries for fracture repairs, amputations, or dental procedures.
   
   
   
   

Features of Surgical Bone Saws

1. Precision Cutting:
   
   
   
   • Designed to make clean and precise cuts, reducing the risk of splintering or fracturing the bone.
   
   
   
   


2. Ergonomic Design:
