KOCHER-LANGENBECK RETRACTOR 35MM X 15MM 21,5CM

KOCHER-LANGENBECK RETRACTOR • 35MM X 15MM • 21.5 CM • CE-CLASS I • ISO 13485:2016

Extra-Tall Blade Combination Retractor for Extreme Deep Retraction and Powerful Fascial Control

The KOCHER-LANGENBECK RETRACTOR 35mm x 15mm is a CE-Class I medical device manufactured according to ISO 13485:2016. This extra-tall blade variant of the universal combination instrument represents the most powerful version, designed for surgical procedures requiring extreme deep retraction of voluminous tissue alongside secure anchoring to resistant structures. The exceptionally tall Langenbeck blade (15mm) penetrates deep into wound edges, while the robust Kocher blade provides firm grip under tension.

Advantages of the Kocher-Langenbeck Retractor (35x15mm):

• Extreme Depth Effect: The 15 mm tall blade enables retraction of the deepest tissue layers in obese patients or deep anatomical regions.
• Maximum Functionality: Combines the deepest surface retraction with the most secure grasping retraction in a single instrument.
• Indispensable for Difficult Access: Specifically developed for procedures with limited visibility and high tissue tension.
• Efficiency in Complex Situations: Reduces the need for additional special retractors and simplifies handling in confined surgical situations.
• Balanced Force Transfer: The reinforced central handle allows secure control even under maximum load.

Primary Fields of Application (Specialty Indications):

• Orthopedics & Trauma Surgery (High-Performance): Revision surgery of hip and knee, deep spinal surgery, complex femoral fractures in obese patients.
• Bariatric Visceral Surgery: Retraction of the extremely thickened abdominal wall in morbid obesity.
• Urology (Complex Cases): Radical cystectomy or prostatectomy in patients with high BMI or after previous surgeries.
• Plastic Surgery (Reconstruction): Deep flap procedures, free tissue transfers with thick tissue flaps.
• Oncologic Major Resections: For deeply seated tumors requiring retraction of voluminous surrounding tissue.

Critical Safety and Application Notes:

• FOR USE BY HIGHLY QUALIFIED AND EXPERIENCED SURGICAL PERSONNEL ONLY. Not suitable for beginners or unskilled assistants.
• Extreme caution with the Kocher blade: Apply only to clearly identified, robust fascial or periosteal structures. Absolute contraindication for any use on parenchymal organs, nerve plexuses, or vascular structures.
• The extreme leverage of the 15 mm tall blade requires utmost care and minimally dosed force application to prevent catastrophic tissue tearing.
• Mandatory inspection for material fatigue, micro-cracks, or deformations before each use.
• Particularly suitable as a strategic guiding instrument within a retractor set, not as a primary dissection instrument.
• Most intensive cleaning of interdental spaces and blade base required during reprocessing.
