Wullstein Ear Knife: Precision Sickle Blade for Microsurgical Otology
The Wullstein Ear Knife from Adas Instruments is expertly crafted for otologists who require absolute sharpness and control during middle ear reconstruction. This micro-surgical instrument is made from premium German Stainless Steel, ensuring an exceptionally fine cutting edge for performing delicate incisions in the tympanic membrane or for elevating the mucosal lining within the middle ear cavity.
Exceptional Engineering & Accuracy
Manufactured from high-grade German stainless steel, each Wullstein knife undergoes a rigorous passivation and boil-test process to ensure maximum longevity and rust prevention. The delicate sickle-shaped blade is ground to extreme sharpness, allowing for effortless tissue separation with minimal trauma. At Adas Instruments, we prioritize 100% technical accuracy, ensuring the blade’s curvature and the shaft’s rigidity provide the exact tactile feedback required for safe micro-dissection near vital structures.
Surgical Applications
- Tympanoplasty: Essential for precisely lifting the tympanomeatal flap or preparing the edges of a perforation for grafting.
- Mastoidectomy: Used to dissect fibrous tissue and mucosa from the mastoid air cells and middle ear.
- Ossiculoplasty: Provides the necessary precision for managing delicate tissue around the ossicular chain.
Care and Maintenance Section
To maintain the ultra-sharp edge of the sickle blade, the instrument should be protected with a dedicated silicone guard during sterilization and storage. It is fully autoclavable and resistant to repeated processing. Adas Instruments ships USA, Europe & worldwide to support specialized surgical centers with elite-tier instrumentation.
