dcsimg Makrolon® Polycarbonate in TorqueSafe™ Torque Instrument Case St

A new twist on traditional medical instruments

Innovative single-use torque instruments utilize tough polycarbonate

For many years, torque-applying instruments have been among the surgical instruments typically used during orthopedic surgeries. They are manufactured as reusable instruments, and are cleaned, reprocessed and recalibrated after each surgical procedure. Now there’s a new twist on this oft-used instrument.

Caltorque Medical Products (CMP), a division of California Torque Products Inc., says its TorqueSafe™ torque instruments give surgical implant original equipment manufacturers (OEMs) an alternative to traditional reusable instruments.

What was traditionally a stainless steel instrument with a silicon over-molded handle has been transitioned to a mostly plastic, cost-effective alternative offering the same at-use performance.

Makrolon® polycarbonate resin from Covestro forms the handles of CMP’s TorqueSafe™ instruments, which are designed for trauma, reconstruction, small bone, cranio maxillofacial fixation, spine and extremity procedures.  

Makrolon® polycarbonate met CMP’s robust requirements of the surgical setting and need for high-stress performance.

According to CMP, other advantages included the material’s compatibility with sterilization modalities, ability to meet care and handling requirements, durability in transport, and global availability. Also important was the material’s ability to exceed in-use environmental and in-situ requirements.

The ability to repurpose materials post-use was yet another benefit of using the Makrolon® polycarbonate resin, since it can be incorporated into the health care community’s recycling programs and procedures, according to CMP.

The main properties of Makrolon® polycarbonate are:

  • Impact resistant
  • Recyclable
  • Lightweight
  • High dimensional stability
  • Easily molded
  • Glass-like transparency
  • biocompatibility
