Problem addressed

Children after spine surgery require frequent examination to monitor the surgery outcome. The common examinaiton used is x-ray which imposes a lot of radiation to the children which may be a hazard to their health.

Innovation

The radiation-free, non-contact measuring device of the present invention can accurately locate multiple screws or implants in a patient's body
A system and devices provide accurate localization of orthopedic implants based on magnetic tracking approach (MTA) technology and without radiation.

Key impact

Free the children from regular x-ray exposure during clinical follow-up
giving surgeons the ability to modify treatment plans in real time during procedures, such as scoliosis correction, in order to enhance treatment effectiveness and improve safety
has a wide range of applications in complex fracture correction, intelligent prosthetic limbs, wearable devices and other scenarios
