A new twist on traditional medical instruments

A new twist on traditional medical instruments

Innovative single-use torque instruments use tough polycarbonate

Orthopedic surgery can fix a range of ailments. Metal, reusable torque instruments are go-to tools for these procedures. Now there’s a new twist on this oft-used instrument.

CalTorque
The handles of TorqueSafe™ instruments, designed for trauma, reconstruction, small bone and other procedures, use Makrolon® polycarbonate from Covestro.

Task

Torque-applying instruments are manufactured as reusable instruments, and are cleaned, reprocessed and recalibrated after each surgical procedure. Caltorque Medical Products (CMP), a division of California Torque Products Inc., sought to revamp the instruments.

Challenge

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

Solution

CMP chose Makrolon® polycarbonate from Covestro to form the handles of its TorqueSafe™ instruments, which are designed for trauma, reconstruction, small bone, cranio maxillofacial fixation, spine and extremity procedures. The material met the robust requirements of the surgical setting and need for high-stress performance. The ability to repurpose materials post-use and exceed in-use environmental and in-situ requirements were also cited by CMP as benefits of using Makrolon® polycarbonate.

CMP selected the material due to its compatibility with sterilization modalities, ability to meet care and handling requirements, durability in transport and global availability.

Makrolon® polycarbonate is an easily molded material, yet it retains its original shape when exposed to heat or humidity because of its high dimensional stability.

Its glass-like transparency makes Makrolon® polycarbonate an attractive option for use in many different applications.
