KOCHER-LANGENBECK RETRACTOR 55MM X 11MM 21,5CM

KOCHER-LANGENBECK RETRACTOR • 55MM X 11MM • 21.5 CM • CE-CLASS I • ISO 13485:2016

Mega-Wide Blade Combination Retractor for Extreme Large-Area Retraction with Simultaneous Fascial Fixation

The KOCHER-LANGENBECK RETRACTOR 55mm x 11mm is a CE-Class I medical device manufactured according to ISO 13485:2016. This mega-wide blade variant represents the ultimate combination of maximum surface effect and precise grasping function. Designed for the most demanding surgical approaches where extremely large tissue areas need to be stably retracted while simultaneous secure anchoring to resistant structures is required.

✔ CE Marking Class I (Regulation (EU) 2017/745)
✔ Mega-Wide Blade Variant – widest available combination retractor
✔ Ultra-wide Langenbeck blade (55x11mm) for unparalleled area retraction
✔ Reinforced 1- or 2-toothed Kocher blade for secure hold even under maximum traction load
✔ High-strength surgical stainless steel 1.4305 – specially designed for high bending and tensile loads
✔ Tested Biocompatibility according to ISO 10993
✔ High-performance forged from one piece with reinforced central axis
✔ Optimal length (21.5 cm) for deep large-area approaches
✔ Sterilizable and reusable

Advantages of the Kocher-Langenbeck Retractor (55x11mm):

• Unparalleled Area Control: The 55 mm wide blade enables retraction of extremely large tissue areas – ideal for mega-laparotomies and extensive orthopedic approaches.
• Strategic Efficiency: Combines two critical functions (area and grasping retraction) in one instrument, reducing the need for additional assistants and retractors.
• Optimal Wound Edge Protection: Protects particularly long incision edges through maximum pressure distribution and minimizes the risk of tissue ischemia.
• Reduced OR Time: Enables rapid exposure of large surgical fields and facilitates switching between different retraction techniques.
• Balanced Design: Despite the extreme width, manageable through thoughtful weight distribution and handle geometry.

• Risk Class: I according to Regulation (EU) 2017/745 (MDR)

Primary Fields of Application (Specialty Indications):

• Visceral Surgery (Mega-Laparotomies): For extensive tumor resections, multivisceral procedures, or revision surgeries with massive adhesiolysis.
• Orthopedic Large Approaches: For extensive reconstructions of the spine, pelvis, or in complex revision arthroplasty.
• Trauma Surgery (Polytrauma): For extensive exposures of multiple compartments or large soft tissue defects.
• Plastic and Reconstructive Surgery: During elevation of extremely large flaps (e.g., latissimus dorsi flap) or debridement of huge areas.
• Oncologic Major Resections: Where maximum exposure is crucial for overview and safety.

Critical Safety and Application Notes:

• FOR USE BY HIGHLY EXPERIENCED AND SPECIALIZED SURGICAL TEAMS ONLY. Requires particular experience in handling extreme instrument sizes.
• Extreme caution with the Kocher blade: Apply only to definitively robust fascial structures with sufficient tissue thickness. Absolute contraindication for thin or vulnerable structures.
• The extreme leverage of the 55 mm wide blade requires highest concentration and dosed force application – uncontrolled traction can lead to massive tissue tears.
• Mandatory Two-Point Control: The instrument should ideally be guided with both hands or at least stabilized.
• Check for deformations, material fatigue, or micro-cracks before each use – particularly along the long blade edges.
• Particularly suitable as a strategic lead retractor in a multi-stage retraction setup.
