A novel stereotactic neurosurgical robot has been developed for precise, minimally invasive procedures. Clinical testing shows successful robotic biopsies for brain lesions, enhancing patient safety and surgical accuracy.

Area of Science:

  • Neurosurgery
  • Robotics
  • Medical Imaging

Background:

  • The development of advanced robotic systems is crucial for improving precision in neurosurgical interventions.
  • Stereotactic neurosurgery requires accurate targeting and instrument manipulation within the cranial cavity.

Purpose of the Study:

  • To introduce a newly developed stereotactic neurosurgical robot designed for enhanced precision and safety.
  • To evaluate the feasibility and initial clinical performance of this robotic system in neurosurgical procedures.

Main Methods:

  • The robot is integrated with a CT scanner, allowing intraoperative imaging and precise head fixation.
  • It features automated skin, skull, and meninges penetration and can manipulate multiple instruments.
  • The system enables target and trajectory selection directly from CT slices on a robotic workstation.
