FAQs
1. What is the difference between a reciprocating and an oscillating sternal saw?
Reciprocating saws use a back-and-forth blade motion, while oscillating saws employ a side-to-side motion. Reciprocating saws are often faster but can be less precise, while oscillating saws are smoother and cause less trauma.
2. How are sternal saws sterilized?
Most sternal saws are autoclavable, meaning they can be sterilized using high-pressure steam. Check the manufacturer’s instructions for specific sterilization parameters, like temperature and time. Bojin Medical (www.bojin-medical.com) specifies sterilization temperatures for their models.
3. What safety features should I look for in a sternal saw?
Essential safety features include a sternum guard to protect surrounding tissues and a variable speed trigger for precise control. Ergonomic design also reduces surgeon fatigue and improves precision.
4. How long is the typical warranty period for a sternal saw?
Warranty periods vary depending on the manufacturer and model. Some manufacturers offer two-year warranties on the handpiece, with shorter warranties on consumables like batteries. Always check the manufacturer’s warranty information.
5. What factors should I consider when choosing a sternal saw?
Factors include the type of saw (reciprocating or oscillating), power source (battery or AC), weight, speed control, safety features, sterilization capabilities, and warranty. The specific needs of the surgery and surgeon preference are also key considerations. Ruijin Medical (ruijinmedical.com) highlights these factors in their product descriptions.
