Solid-Phase Bauer Intra Oral Retractor (21cm) for Precise Ramus Exposure
The Bauer Intra Oral Retractor is a premier instrument in the orthognathic surgical kit, specifically engineered for the secure displacement of soft tissue along the posterior border of the mandibular ramus. Functioning as a high-performance sigmoid guard, this 21cm instrument features a specialized hook-shaped blade that “wraps” around the bone to provide a stable, deep-field window for the surgeon. Adas Instruments ensures that each mandibular ramus shield is balanced for center-point ergonomics, allowing for maximum retraction force with minimal hand fatigue for the assistant. We ship USA, Europe & worldwide via DHL, FedEx, and UPS to deliver German steel instruments that surgeons trust for their anatomical accuracy and structural resilience.
Why Maxillofacial Surgeons Choose Our Bauer Retractor
- Deep-Reach Geometry: Features a specialized 21cm elongated shaft and hooked distal end to act as a versatile sigmoid guard, protecting the neurovascular bundle during bone cuts.
- Titan-Scope Visibility: Specifically designed with a slender neck to function as a reliable mandibular ramus shield, ensuring the instrument does not block the surgeon’s line of sight during vertical ramus osteotomies.
- Anatomical Contouring: Available in left and right-handed versions to perfectly match the contralateral borders of the mandible for a precise, slip-free purchase.
- Steady-Stance Resilience: Forged from premium surgical stainless steel, engineered to withstand the significant retraction pressure required in dense posterior facial sites.
Primary Surgical Applications
- Retracting the posterior border of the ramus during a Bilateral Sagittal Split Osteotomy (BSSO).
