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 medical grade 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 high quality medical grade 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.
