Rosen Ear Knife: Precision Micro-Dissection in Otology
The Rosen Ear Knife from Adas Instruments is expertly crafted for otologists requiring absolute precision in the confined spaces of the auditory canal. This micro-surgical instrument is made from premium German Stainless Steel, ensuring an exceptionally sharp cutting edge for lifting the tympanomeatal flap or performing delicate incisions during middle ear operations.
Exceptional Engineering & Accuracy
Manufactured from high-grade German stainless steel, each Rosen knife undergoes a rigorous passivation and boil-test process to ensure maximum longevity and rust prevention. The hexagonal or round handle provides a balanced, non-slip grip, allowing for the subtle, controlled rotations needed to navigate narrow anatomical pathways. At Adas Instruments, we prioritize 100% technical accuracy, ensuring the blade angle and sharpness provide the exact tactile feedback required for safe micro-dissection.
Surgical Applications
- Otology & Tympanoplasty: Essential for making the initial incisions in the ear canal and precisely elevating the delicate skin of the eardrum.
- Myringotomy: Used to create a clean, controlled opening in the tympanic membrane for fluid drainage or pressure equalization tube insertion.
- Stapedectomy: Provides the necessary precision for tissue management around the ossicular chain during reconstructive hearing surgery.
Care and Maintenance Section
To maintain the ultra-sharp edge of the micro-blade, the instrument should be protected with a silicone tip during sterilization and storage. It is fully autoclavable; however, avoid contact with other heavy instruments that could dull the fine tip. Adas Instruments ships USA, Europe & worldwide to support specialized surgical centers with elite-tier instrumentation.
