Описание
Он XISHAN Rigid Otoscope Series (EDS-OTO Series) is a compact, high-resolution optical telescope portfolio engineered for minimally invasive Endoscopic Ear Surgery (EES), transcanal myringoplasty, tympanoplasty, stapedectomy, and middle ear exploration.
Featuring ultra-slim 2.7 mm and 3.0 mm outer profiles with high-magnification optical glass, XISHAN otoscopes provide panoramic illumination and distortion-free visualization inside narrow ear canals, enabling surgeons to visualize hidden middle ear anatomical recesses without extensive bone removal.
Core Optical & Clinical Advantages
Ultra-Slim 2.7 mm / 3.0 mm Profile
Compact outer sheath dimensions provide generous instrument clearance within narrow external auditory canals, reducing the need for canalplasty.
High-Contrast Micro-Optics
Multi-coated precision lenses deliver razor-sharp contrast for microscopic middle ear structures, including the ossicular chain, chorda tympani, and facial nerve canal.
Scratch-Resistant Sapphire Distal Lens
Laser-welded optical sapphire distal window resists tool contact abrasion and provides enduring optical clarity under intense LED illumination.
Hermetic 134°C Autoclavable Housing
Seamless medical stainless steel construction engineered for high durability under repeated 134°C steam autoclaving and low-temp plasma sterilization.
Viewing Angle Options & Clinical Application
1. 0° Direct Forward Otoscope (SKU: EDS-OTO-0)
Direct linear optical path designed for initial transcanal surveys, myringotomy, ventilation tube insertion, and direct-line stapes surgery.
2. 30° Wide-Angle Oblique Otoscope (SKU: EDS-OTO-30)
The clinical standard for Endoscopic Ear Surgery (EES). Rotating the telescope allows surgeons to look around the tympanic annulus into hidden corners, such as the sinus tympani, facial recess, epitympanum, and hypotympanum.
Clinical Indications & Procedures
- Endoscopic Ear Surgery (EES): Transcanal endoscopic tympanoplasty (TET), myringoplasty, and exploration of middle ear clefts.
- Cholesteatoma Surgery: Eradication of residual cholesteatoma matrix in deep retrotympanum and sinus tympani recesses.
- Ossiculoplasty & Stapes Surgery: Stapedotomy, stapedectomy, and total/partial ossicular replacement prosthesis (TORP/PORP) placement.
- Facial Nerve Decompression: High-magnification inspection of the tympanic and mastoid segments of the facial nerve.
