This upturned circular cutting punch produces a 3.5mm diameter aperture in a single motion for tympanic membrane perforation creation or round window niche work during otologic and skull base procedures. The upturned geometry maintains visualization during the cutting stroke, and the 160mm working length reaches into the mastoid cavity. Stainless steel provides durable cutting performance.
Features & Benefits
- 3.5mm diameter circular aperture for tympanic and osseous work
