KOCHER RETRACTOR 6 PRONGS MEDIUM SHARP 22,0CM

KOCHER RETRACTOR • 6 SEMI-SHARP PRONGS • 22.0 CM • CE CLASS I • ISO 13485:2016

High-Performance Retractor for Broadest Tissue Preservation Under Tension

The KOCHER Retractor with 6 semi-sharp prongs, 22.0 cm is a Class I medical device according to ISO 13485:2016. This special-order instrument represents the ultimate solution when extremely broad-based and powerful retraction of large-volume soft tissue is required, while simultaneously upholding the principle of maximum preservation and minimal tissue trauma as the top priority.

Product Highlights:

✔ Certified according to ISO 13485:2016
✔ CE marking Class I (Regulation (EU) 2017/745)
✔ KOCHER design with reinforced, ergonomic hammer handle
✔ 6 semi-sharp prongs for unparalleled surface adhesion with minimal penetration
✔ High-quality, high-strength stainless steel 1.4435/316L – corrosion-resistant and biocompatible
✔ Biocompatibility tested according to ISO 10993
✔ Semi-sharp tips with optimized pressure distribution geometry
✔ Length 22.0 cm for deep and extensive surgical exposure
✔ Autoclavable and reusable under defined processes

Advantages of the KOCHER Retractor (6 semi-sharp prongs):

• Maximum Surface Adhesion with Minimal Trauma: Six semi-sharp prongs create an exceptionally large contact area, distributing the required retraction pressure to an absolutely minimal, tissue-sparing level per unit area.
• Perfect Pressure Distribution: Prevents local pressure necrosis and deep tissue tears that can occur with sharp or fewer prongs under high tension.
• Ideal Tension Control: Enables the holding and retraction of large muscle groups (e.g., entire thigh or back muscles) with an even, tissue-tolerable tension.
• Reduced Postoperative Pain and Swelling Risk: The tissue-preserving technique can contribute to improved postoperative rehabilitation.
• Specialized Tool for Gentle Major Surgery: Developed for demanding reconstructive and oncological surgeries where preserving soft tissue integrity is prognostically decisive.

Technical Specifications:

Fields of Application (Highly Specialized):

• Reconstructive orthopedic tumor surgery requiring soft tissue preservation
• Complex revision arthroplasty of the hip and knee with extensive soft tissue release
• Extensive dorsal spinal procedures aiming for muscle and fascia preservation
• Plastic and reconstructive surgery for large-scale defects with nearby microvascular anastomoses
• Special trauma surgery focusing on biological osteosynthesis and soft tissue healing

CRITICAL APPLICATION NOTES:
• FOR USE BY SPECIALIZED SURGEONS WITH EXPERIENCE IN TISSUE-PRESERVING SURGICAL TECHNIQUE ONLY.
• DESPITE PRESERVATIVE DESIGN: The instrument transmits significant forces. Requires deep understanding of tissue biomechanics and extremely controlled, measured application.
• Mandatory Pre-Inspection: Before each use, all six prongs must be checked for identical tip geometry, sharpness, and structural integrity. A single damaged prong renders the instrument unusable.
• Indication: Only for large-volume, but not extremely dense or scarred soft tissue under tension. Unsuitable for fascia or extremely firm tissue.
• Reprocessing: Due to the narrow spaces between prongs, careful manual pre-cleaning is mandatory to remove protein residue. Automated cleaning alone is insufficient.
• Discard Policy: In case of any deviation in tip geometry, bending, loss of polish, or signs of material fatigue, the instrument must be immediately withdrawn from use and submitted for specialized maintenance.
