Seemann-Seiffert Mouth Gag: Precision Retraction for Oropharyngeal Surgery
The Seemann-Seiffert Mouth Gag from Adas Instruments is a specialized retractor that combines the stability of a fixed frame with the flexibility needed for various patient anatomies. Crafted from premium German Stainless Steel, this instrument is a staple in ENT theaters, providing surgeons with a reliable, hands-free method to maintain oral access throughout complex dissections.
Exceptional Engineering & Accuracy
Manufactured from high-grade German stainless steel, each Seemann-Seiffert gag undergoes a rigorous passivation process to ensure maximum structural integrity. The ratchet system is designed to lock securely at multiple intervals, preventing accidental closure during surgery. At Adas Instruments, we prioritize 100% technical accuracy, ensuring the anatomical curve of the frame distributes pressure evenly across the dental arches to minimize post-operative patient discomfort.
Surgical Applications
- Tonsillectomy: Provides the necessary wide-angle exposure to access both the superior and inferior poles of the tonsil.
- Adenoidectomy: Stabilizes the jaw to allow for clear visualization of the nasopharynx via indirect mirror or endoscopic view.
- Cleft Palate Repair: Offers the stable, wide-open field required for delicate reconstructive suturing of the palate.
Care and Maintenance Section
To preserve the precision of the ratchet and pivot points, the Seemann-Seiffert Mouth Gag should be cleaned in the fully open position. Use a soft-bristled brush to remove any biological residue from the locking teeth before autoclaving. Regular application of medical-grade lubricant to the sliding mechanisms is highly recommended for smooth operation. Adas Instruments ships USA, Europe & worldwide to support specialized surgical centers with elite-tier instrumentation.
