COMPARISON OF A ROBOTIC AND PATIENT-MOUNTED DEVICE FOR CT-GUIDED NEEDLE PLACEMENT: A PHANTOM STUDY

Scharll, Y., Mitteregger, A., Lamier, G. et al. Comparison of a Robotic and Patient-Mounted Device for CT-Guided Needle Placement: A Phantom Study. Journal of Clinical Medicine, 11, 3746 (2022). https:doi.org/10.3390.jcm11133746

Assessment of the Puncture Cube as compared to a robotic navigation device.  In-vitro accuracy and time required were compared in this phantom study. 


RESULTS
The Puncture Cube resulted in a mean nominal distance of between 3.84 and 4.41mm from the target, depending on the CT slice thickness.  Although slightly less accurate than the robotic device, the Puncture Cube's performance was competitive with other navigational systems on the market. Beyond the accuracy assessment, the following key advantages are highlighted:

  • 30% faster procedure time, not including set up or breakdown time

  • flexibility to use the system across multiple CT scanners at the same time

  • no floor space taken in the CT room

  • much faster return on ROI while providing accuracy gains sufficient for all but the long tail of complex procedures

EVALUATION OF A NOVEL, PATIENT-MOUNTED SYSTEM FOR CT-GUIDED NEEDLE NAVIGATION—AN EX VIVO STUDY

Mokry, A., Willmitzer, F., Hostettler, R. et al. Evaluation of a novel, patient-mounted system for CT-guided needle navigation—an ex vivo study. Neuroradiology 61, 55–61 (2019).

Assessment of the Puncture Cube as compared to the standard of care Free Hand Method.  Accuracy and time requirements were compared in this ex-vivo, phantom study. 


RESULTS
Compared to a conventional free-hand procedure, the use of the Cube Navigation System with a Puncture Cube resulted in a statistically significantly improved accuracy (3.4 mm ± 2.3 mm vs 4.9 mm ± 3.2 mm with the free hand method) and overall lower intervention time (168 s ± 28.5 s versus FHM 200 s ± 44.8 s). Furthermore, the number of CT scans was reduced to 2.3 versus FHM 2.8.
