Description
Le XISHAN Rigid Sinoscope Series (EDS-SIN Series) is a wide-angle optical telescope portfolio engineered specifically for Functional Endoscopic Sinus Surgery (FESS), trans-nasal skull base interventions, and rhinologic diagnostics.
Featuring advanced optical glass coatings with a high-durability distal sapphire lens, XISHAN sinoscopes deliver panoramic, distortion-free visualization of complex paranasal sinus ostia, providing surgeons with sharp contrast between mucosal pathology and adjacent critical neurovascular structures.
Engineering Highlights
Wide-Angle FESS Optics
Multi-coated precision optics provide high edge-to-edge sharpness and wide field coverage across the ethmoid, maxillary, and frontal sinus cavities.
Scratch-Resistant Sapphire
Diamond-hard optical sapphire front window resists tool abrasion during simultaneous introduction of power debriders and surgical burs.
Reinforced Stainless Steel
Laser-welded stainless steel body with high bending rigidity, fully rated for repeated 134°C steam autoclaving and STERRAD plasma cycles.
Viewing Angle Options & Sinus Landmark Guidance
1. 0° Direct Forward Sinoscope (SKU: EDS-SIN-0)
Provides a straight-ahead optical perspective ideal for nasal cavity survey, septoplasty, turbinoplasty, and linear anterior ethmoid dissection.
2. 30° Wide-Angle Oblique Sinoscope (SKU: EDS-SIN-30)
The clinical gold standard for standard FESS procedures. Rotating the scope provides full panoramic views of the uncinate process, maxillary sinus natural ostium, posterior ethmoids, and sphenoid sinus.
3. 70° Steep Angle Sinoscope (SKU: EDS-SIN-70)
Essential for inspecting difficult-to-reach anatomical recesses, including the frontal recess, frontal sinus drainage pathway, superior maxillary sinus wall, and agger nasi cells.
Clinical Indications & Procedures
- Functional Endoscopic Sinus Surgery (FESS): Maxillary antrostomy, ethmoidectomy, sphenoidotomy, and frontal sinusotomy.
- Nasal & Sinus Pathology: Polypectomy, inverted papilloma resection, and fungal sinusitis clearing.
- Trans-Nasal Skull Base Surgery: Pituitary adenoma resection, CSF leak repair, and optic nerve decompression.
- Dacryocystorhinostomy (Endo-DCR): Lacrimal sac exploration and osteotomy.
