Single-use torque instruments depend on Makrolon® 

Copied to clipboard

Reusable orthopedic torque handles for trauma, reconstruction and other procedures have long been made almost entirely from stainless-steel. Caltorque Medical Products sought to provide similar performance at lower cost-per-use by using Makrolon® in its new single-use TorqueSafe™ handles.

Task

Produce a single-use torque handle with no performance loss

Orthopedic torque-applying instruments are typically manufactured as reusable items that need to be cleaned, reprocessed and recalibrated after each surgical procedure. Caltorque Medical Products (CMP) wished to replace these handles with single-use items that would do away with the expensive refurbishment process. To achieve this they required a material that would ensure there was no loss of performance during surgery and that could be repurposed after use for environmental reasons.
Challenge

Provide a material robust enough to replace stainless steel

CMP wanted to take what was traditionally a stainless steel, reusable instrument with a silicon over-molded handle and transition it to a mostly plastic, cost-effective alternative offering the same at-use performance.
Solution

Makrolon® has what it takes to cope with the pressure

After consulting with us, CMP chose Makrolon® for the handles of its TorqueSafe™ instruments. The company went with this tough, biocompatible material due to its ability to endure the high levels of stress placed on medical equipment of this type during trauma, reconstruction, small bone, cranio-maxillofacial fixation, spine and extremity procedures. The fact that medical-grade Makrolon® is sterilization-friendly is also key considerations.

Why Makrolon® was the right solution for TorqueSafe™ handles

  • Extremely strong:  Material can handle high physical load and is impact resistant.
  • Sterilizable: Not damaged or altered by sterilization procedures.
  • Ease of use: Flows as easily and releases from the mold with no difficulty.
  • Dimensionally stable: Retains its original shape when exposed to heat or humidity.
  • Biocompatible: Has no negative impact on bone or tissue.
