A system and method for establishing an insertion path for a surgical implant

System for determining insertion path for surgical implant for placing screws in spinal pedicle, has processing unit that receives insertion path based on first tracking signals, and compares second tracking signals with insertion path.

The system (10) has portable probe unit (12) that includes ultrasonic transducer and ultrasonic receiver (18) for exploring tissue region. An insertion unit (14) produces insertion path in tissue region. Tracking units (22,24) detect spatial position and/or orientation of respective probe unit and insertion unit with respect to tissue region, and outputs respective tracking signals. A processing unit (20) receives planned insertion path based on first tracking signals, and compares second tracking signals with planned insertion path.

USE – System for determining insertion path for surgical implant for placing screws in spinal pedicle.

ADVANTAGE – The system allows the surgeon to check whether the insertion path is drilled straight corresponding to planned path of insertion, The surgeon is enabled to make immediate correction while detecting the deviations so that the risk of misplacement of surgical implant during the surgical procedure is avoided. The complexity of receiving the tracking signal is avoided.
