Metal Industries Research & Development Centre (MIRDC) Continuous Tracking Surgical Assistance System (CTSAS)

The world’s first real-time tracking multi-vertebral surgical navigation

From the winners: “CTSAS is the first surgical navigation system using the dodecahedral tracker which provides maximum viewing angles with a greatly reduced size. Combined with real-time visualization and navigation corrections of patient’s anatomy, the system can track each vertebra with improved accuracy, especially in the procedure of multilevel spinal surgeries.”

“Conventional navigation devices use large reference frames as their trackers. When the tracker is blocked, which happens often, tracking is discontinued. Besides, the conventional tracker only ensures acceptable accuracy within 2 vertebral levels, so in multilevel surgery the time-consuming, laborious process of registration must be repeated. CTSAS features small dodecahedral trackers for fluent tracking, and reduces the operation time of multilevel procedures since re-registration is not needed. For example, the pedicle screw placement of 12 pedicles (T12-L5) takes less than 2.5 hours without compromising surgical safety and accuracy.”

“CTSAS reduces intraoperative radiation exposure compared to fluoroscopy-guided procedures. While conventional navigation devices using NDI tracking system tend to have line-of-sight issues due to their large trackers, CTSAS provides fluent tracking with smaller dodecahedral trackers. Furthermore, CTSAS can track more than 3 vertebral levels, capturing real-time vertebral motions during surgery, so unnecessary delays caused by re-registration are avoided. All this has improved the user experience, ensured better treatments and surgical outcomes, and brought a breakthrough in minimally invasive multilevel spinal surgery.”
