Laboratory Evaluation of a Robotic Operative Microscope - Visualization Platform for Neurosurgery

Area of Science:

• Neurosurgery
• Surgical Technology
• Medical Imaging

Background:

• A novel robotic visualization platform with advanced user-control features was developed.
• The platform's performance was compared against the established operative microscope model.

Purpose of the Study:

• To evaluate the performance and usability of a new robotic visualization platform in neurosurgical applications.
• To compare the new platform's capabilities, including fluorescence and imaging, with a traditional operative microscope.

Main Methods:

• Anatomical dissections and functional assessments (robotic, exoscopic, endoscopic, fluorescence) were conducted in a research laboratory.
• Usability and functionality were tested in a clinical operating room setting over one year.
• Specific features like point lock, pivot point control, 3D exoscopic, and endoscopic assistance were evaluated.

Main Results:

• The robotic microscope demonstrated superior sensitivity for fluorescein sodium and enhanced detail in non-fluorescent backgrounds.
• Image quality was comparable to traditional microscopes, with improved near-infrared indocyanine green imaging for blood flow assessment.
• Novel control features (point lock, pivot point) facilitated 3D virtual reality demonstrations and deep corridor access; 3D exoscopic and endoscopic modes proved useful in various surgical cases.

Conclusions:

• The robotic platform offers significant improvements, including enhanced intraoperative fluorescence visualization, an integrated micro-inspection tool, and superior ocular imaging.
• New robotic movements enhance surgeon ergonomics, comfort, and viewing quality, with potential benefits for anatomy instruction.
• Additional surgeon training is recommended to fully leverage the platform's numerous advanced features and operational modes.
