KOCHER RETRACTOR 8 PRONGS BLUNT 22,0CM

KOCHER RETRACTOR • 8 BLUNT PRONGS • 22.0 CM • CE CLASS I • ISO 13485:2016

The Definitive Soft Tissue Protection Instrument for Exposing Entire Body Compartments

The KOCHER Retractor with 8 blunt prongs, 22.0 cm is a Class I medical device according to ISO 13485:2016. This extraordinary specialized instrument represents the pinnacle of atraumatic retraction technology. Eight fully blunt, broad-surface prongs are engineered to enable the exposure of large body cavities while simultaneously reducing any risk of injury to surrounding soft tissue, organs, and vascular structures to an absolute minimum.

Advantages of the KOCHER Retractor (8 blunt prongs):

• Biomechanical Perfection: Eight broadly arranged prongs simulate an almost flat support, lowering specific tissue pressure below the critical ischemia threshold – ideal for prolonged procedures.
• Ultimate Protection for Parenchyma: Designed for direct contact with the most sensitive organs (liver, spleen, kidney, lung) in tumor and transplant surgery.
• Revolutionary Exposure Technique: Enables securing and retracting entire intestinal convolutes, the greater omentum, or mobilized organ blocks in a single, controlled motion.
• Prevention of Secondary Complications: Significantly reduces the risk of postoperative adhesions, seroma formation, and tissue necrosis through minimal-pressure application.
• Engineering Marvel: Each of the eight prongs is computer-designed and aligned for optimal force distribution.

CRITICAL NOTES AND SAFETY PROTOCOLS:
• FOR USE BY HIGHLY QUALIFIED SURGEONS IN CERTIFIED MAXIMUM CARE CENTERS ONLY.
• NOT A GENERAL SURGICAL INSTRUMENT. Use requires strictly documented indication and risk-adapted assessment.
• PRE-OPERATIVE INSPECTION MANDATORY: Before each use, all eight prongs must be inspected under magnifying loupes for perfect surface integrity, exact alignment, and structural homogeneity.
• APPLICATION TECHNIQUE: Requires special training. Only vertical, flat traction is permitted. Absolute contraindication for prying movements.
• REPROCESSING PROTOCOL: Highest hygiene standards. The instrument requires a dedicated reprocessing protocol from the OR table to sterilization. Regular inspection by manufacturer service.
• DISCARD POLICY: In case of any deviation from target geometry, micro-scratches, polish alterations, or even suspicion of material fatigue, the instrument must be immediately and permanently withdrawn from use and returned to the manufacturer for analysis. Do not reuse under any circumstances.
