The Maximum Solution for Extreme Retraction Tasks of Massive Soft Tissue Areas
The KOCHER Retractor with 6 sharp prongs, 22.0 cm is a Class I medical device according to ISO 13485:2016 and represents the ultimate stage of manual sharp retraction instruments. This specialized tool is designed for the most challenging surgical situations where extremely broad-based, secure, and powerful retraction of massive, highly tense soft tissue areas is essential.
Product Highlights:
✔ Certified according to ISO 13485:2016
✔ CE marking Class I (Regulation (EU) 2017/745)
✔ Classic KOCHER design with voluminous hammer handle
✔ 6 sharp prongs for extreme holding power and maximum surface adhesion
✔ High-grade stainless steel 1.4401/316L – corrosion-resistant and biocompatible
✔ Biocompatibility tested according to ISO 10993
✔ Precisely ground, sharp prong tips for deep anchorage
✔ Optimal length of 22.0 cm for deep and extensive surgical sites
✔ Autoclavable and reusable
Advantages of the KOCHER Retractor (6 sharp prongs):
• Maximum Surface Adhesion: Six sharp prongs engage and penetrate large tissue areas to ensure absolutely stable and secure retraction even under extreme conditions.
• Ultimate Force Distribution: Traction force is optimally distributed over a wide tissue area, minimizing point overload and the risk of tissue tearing.
• Definitive Holding Capacity: Developed for situations where conventional 3- or 4-prong hooks are insufficient. Reliably prevents slippage from very powerful muscle or fascial tissue.
• Controlled Force Application: The massive hammer handle allows for precise and low-fatigue handling despite the high force required.
• Custom Manufacturing Quality: Crafted using complex forging techniques to withstand enormous mechanical stress.

Fields of Application (Special Indications):
• Orthopedic tumor surgery with resection of large muscle compartments
• Extensive revision and infection surgery of the musculoskeletal system with massive scar plate formation
• Complex spinal procedures requiring access to deep back muscles (e.g., dorsal fusions for scoliosis)
• Trauma surgery with extensive soft tissue destruction (e.g., high-velocity trauma)
• Special reconstructive procedures following major amputations
CRITICAL APPLICATION NOTES AND SAFETY WARNINGS:
• FOR USE BY SPECIALIZED EXPERTS WITH PARTICULAR EXPERIENCE IN MAJOR SURGERY ONLY.
• HIGH-RISK PRECISION INSTRUMENT. Improper use can lead to catastrophic tissue damage.
• Mandatory Requirement: A detailed visual, functional, and sharpness inspection of all six prongs and the handle must be performed before each use.
• Strict Indication! Only for the most massive, dense tissue structures (e.g., large muscle bellies, thick fascial plates). ABSOLUTELY UNSUITABLE for any normal or vulnerable tissue.
• Requires outstanding surgical finesse and biomechanical understanding to avoid crossing the line between necessary holding power and tissue traumatization.
• Reprocessing: Particularly careful cleaning of the narrow spaces between prongs is required. Regular professional sharpness and function checks are mandatory.
• MANDATORY DISCARD if even the slightest quality defects are present (dulling, minimal bending, hairline crack, loosening of a prong). No self-repair! The instrument must be sent to specialized service.
