Wide-Blade Combination Retractor for Large-Area Retraction with Precise Fascial Control
The KOCHER-LANGENBECK RETRACTOR 40mm x 11mm is a CE-Class I medical device manufactured according to ISO 13485:2016. This wide-blade variant of the classic dual-function retractor combines an extremely wide Langenbeck blade for gentle area retraction with a precise Kocher blade for secure fascial fixation. Ideal for procedures where large tissue areas need to be retracted while simultaneous precise traction on firm structures is required.
Product Highlights:
✔ Certified according to ISO 13485:2016
✔ CE Marking Class I (Regulation (EU) 2017/745)
✔ Wide-blade variant with largest surface effect in the combination retractor series
✔ Extremely wide Langenbeck blade (40x11mm) for maximum area retraction
✔ Precise 1- or 2-toothed Kocher blade for controlled grasping retraction
✔ High-quality surgical stainless steel 1.4301 – rust-proof, biocompatible and autoclavable
✔ Tested Biocompatibility according to ISO 10993
✔ Solid one-piece construction for optimal stability
✔ Optimal length (21.5 cm) for deep anatomical regions
✔ Sterilizable and reusable
Advantages of the Kocher-Langenbeck Retractor (40x11mm):
• Maximum Area Coverage: The 40 mm wide blade enables retraction of large tissue areas in a single motion, ideal for long incisions.
• Optimal Pressure Distribution: Distributes traction forces evenly over a large area, minimizing local tissue trauma.
• Strategic Function Combination: Switch between broad area retraction and targeted fascial retraction without instrument change.
• Efficiency Increase: Reduces the number of retractors needed for large surgical approaches.
• Depth-Adapted: The length of 21.5 cm allows ergonomic work even in deeper regions.

Primary Fields of Application:
• General and Visceral Surgery: Major laparotomies, liver resections, bariatric surgical procedures.
• Orthopedics: Extensive approaches in hip and knee arthroplasty, spinal surgery.
• Vascular Surgery: Exposure of longer vascular segments, particularly in abdominal and pelvic surgery.
• Plastic Surgery: Large-area flap elevation, debridement of extensive areas.
• Thoracic Surgery: Retraction during thoracotomies with wide access.
Safety and Application Notes:
• FOR USE BY SURGICAL PROFESSIONALS ONLY.
• Apply Kocher blade only to firm fascial/tendinous structures. Do not use on parenchymal organs or sensitive structures.
• The wide Langenbeck blade requires even, broad-surface application to avoid edge pressure on tissue.
• Ensure straight alignment when using the wide blade to prevent twisting or slipping.
• Check for damage before each use, particularly deformations of the wide blade.
• Thoroughly clean both blade types during reprocessing, especially the interdental spaces of the Kocher blade.
