Area of Science:

  • Neurosurgery
  • Medical Devices
  • Surgical Technology

Background:

  • Current stereotactic systems are mechanically cumbersome and limited.
  • There is a need for more versatile and compact stereotactic systems.
  • Improved systems can enhance surgical workflow and broaden treatment applications.

Purpose of the Study:

  • To develop a compact stereotactic system with reduced footprint and broad targeting capabilities.
  • To improve versatility in frame placement and surgical workflow.
  • To create a low-cost, rapidly deployable stereotactic system.

Main Methods:

  • Designed a stereotactic system based on the center-of-arc principle.
  • Developed 3D-printed and conventionally machined fabrication variants.
  • Tested mechanical and image-guided accuracy in phantom studies (MRI, CT) and cadaver specimens for deep brain stimulation (DBS) surgery.

Main Results:

  • Developed a small (7.7 × 5.4 cm²) device platform adaptable to curvilinear bone.
  • Achieved MRI-guided accuracy with a vector error of 1.79 ± 0.41 mm in phantoms.
  • Demonstrated surgical targeting accuracy of 1.83 ± 0.15 mm in DBS surgery with a bilateral implantation time of 78.3 ± 5.4 min.

Conclusions:

  • A light, compact stereotactic system with accuracy comparable to clinical standards was developed.
  • The system's flexibility enhances stereotactic capabilities for neurosurgery and beyond.
  • This technology is suitable for clinical translation, offering improved versatility and workflow.
