OPTO
OPTO is a comprehensive, high-performance surgical navigation system for neurosurgery and ENT. Using advanced technology and a high-precision IR camera, it offers surgeons more accurate and reliable navigation during surgery.
Key Features
- Standalone planning station with full capabilities
- Compact design with high maneuverability
- Easy positioning of the surgeon's dedicated display
- Wide surgical coverage with long adjustable arms
Applications
Neurosurgery Applications
The brain is the most complex structure in the world, requiring precise surgical decisions and careful planning to minimize patient risk. The navigation system can be used for:
- Tumor biopsy
- Visualization of critical brain structures
- Tumor resection
ENT Applications
Like skull surgeries, ENT procedures require high precision to navigate very narrow pathways and cavities in this region. The navigation system in ENT can be used for:
- Sinus surgery
- Cyst and polyp removal
- Optic nerve decompression
