A new robotic system assists CT-guided clinical punctures for various procedures. Early results show feasibility for complex cases, with potential for improved accuracy and efficiency in image-guided therapy.

Area of Science:

  • Medical Robotics
  • Image-Guided Therapy
  • Minimally Invasive Surgery

Background:

  • Robotic assistance is emerging in minimally invasive procedures.
  • CT-based interventions require high precision and navigation support.

Purpose of the Study:

  • To evaluate the feasibility and clinical application of a new CE-certified robotic assistance device for CT-based punctures.
  • To assess the integration and performance of the robotic system within an interdisciplinary therapy suite.

Main Methods:

  • Six clinical punctures were performed using the robotic assistance device in a Multifunctional Image-Guided Therapy Suite (MIGTS).
  • Procedures included bone and soft-tissue interventions, pelvic fracture fixation, radiofrequency ablation, and drainage.
  • The device provided support for trajectory planning, insertion point recognition, and needle guidance.
