Ctq Spine develops a countertorque screwdriver for spinal surgery that delivers precise final torque without requiring surgeon recalibration, reducing wrist and shoulder strain. The system uses disposable pre‑set torque limiters for 100 % reproducible torque while fully isolating countertorque to prevent residual forces in the pedicle construct, and the instrument is lighter and smaller than earlier prototypes.

Problem
Spinal surgeons often need to apply a precise final torque to pedicle screws, but conventional tools require awkward manual balancing, leading to surgeon fatigue and risk of uncontrolled residual torque in the construct.
Solution
The CTQ Spine Countertorque Screwdriver provides a dedicated mechanism that separates torque and counter‑torque actions, allowing the surgeon to apply the final torque effortlessly without straining the wrists, elbows, or shoulders. Disposable pre‑set torque limiters ensure that each tightening reaches the exact target torque, delivering 100 % reproducible results. The main screwdriver body is reusable, while the torque limiters are single‑use, guaranteeing consistent performance across procedures. By minimizing residual torque, the system enhances construct stability and patient safety during spinal fixation surgeries.
Target Audience
Primary customers are spinal surgeons and orthopedic surgery centers that perform pedicle screw fixation procedures.
