Advantages of the KOCHER Retractor (4 sharp prongs):

• Ultimate Holding Power: Four sharp prongs provide maximum tissue anchorage and allow the application of significant traction forces with minimal risk of slippage.
• Broad-Area Grasping: Ideal for retracting massive muscle groups (e.g., back, gluteal, thigh muscles) or large fascial plates.
• Superior Stability: The high number of prongs optimally distributes traction force over a larger tissue area, protecting against point perforations.
• Precision-Controlled: The anatomically shaped hammer handle allows for controlled and low-fatigue handling even during prolonged use.
• Industrial Quality: Forged using single-piece forging technique for highest load capacity and lasting precision.

• Plastic and reconstructive surgery for large flap procedures
• Specific procedures in general surgery involving a massive abdominal wall

Critical Application and Safety Warnings:
• For use by HIGHLY SPECIALIZED, EXPERIENCED SURGICAL PERSONNEL ONLY.
• HIGH-RISK INSTRUMENT! Due to its sharpness and force transmission, utmost care and surgical judgment are required.
• Perform a comprehensive visual and functional inspection before each use (sharpness, firmness of all prongs, no cracks).
• Strictly indicated for massive, dense tissue. Absolute contraindication for delicate structures (nerves, blood vessels, parenchymal organs, small bowel).
• Requires a deep understanding of tissue biomechanics to avoid tearing or severe crush injury to the retracted tissue.
• During reprocessing: Pay special attention to cleaning between the prongs and preserving sharpness.
• Immediate discard if signs of dulling, micro-cracks, bending, or loosening of a prong are present. Do not re-sharpen yourself! Professional reconditioning is required.
