KOCHER RETRACTOR 8 PRONGS MEDIUM SHARP 22,0CM

Art.Nr.: VUBU-07-18008

KOCHER RETRACTOR • 8 SEMI-SHARP PRONGS • 22.0 CM • CE CLASS I • ISO 13485:2016

The Specialized Instrument for Ultimate Soft Tissue Preservation During Massive Area Retraction

The KOCHER Retractor with 8 semi-sharp prongs, 22.0 cm is a Class I medical device according to ISO 13485:2016 and represents the highest echelon of tissue-preserving retraction instruments. This tool was developed for exceptionally specialized procedures where extremely broad-based retraction of large-volume soft tissue is imperative, and simultaneously every quantum of tissue trauma must be avoided to maximize biological healing potential.

Product Highlights:

✔ Certified according to ISO 13485:2016
✔ CE marking Class I (Regulation (EU) 2017/745)
✔ KOCHER special design with wide, powerful hammer handle
✔ 8 semi-sharp prongs for maximum surface adhesion with minimal-invasive penetration
✔ High-strength, biocompatible premium stainless steel 1.4435/316LVM (vacuum melted)
✔ Biocompatibility tested according to ISO 10993
✔ Precision-ground semi-sharp tips with optimized pressure profile
✔ Length 22.0 cm for deep and extensive exposures in reconstructive surgery
✔ Autoclavable and reusable under strictest protocols

Advantages of the KOCHER Retractor (8 semi-sharp prongs):

• Biologically Optimized Retraction: Eight semi-sharp prongs create a maximum contact area, distributing retraction pressure so evenly and gently that microcirculation and tissue structure are preserved optimally.
• Prevention of Secondary Damage: Designed to significantly reduce iatrogenic muscle and soft tissue damage during lengthy procedures with extensive exposure.
• Support of Biological Healing: Minimizes the risk of postoperative swelling, hematomas, and tissue necrosis that can delay the healing process.
• Precision Tool for Microsurgical Environments: Enables stable conditions near microsurgical anastomoses without endangering surrounding tissue with sharp tips.
• Engineering Precision: Each prong is individually shaped and aligned to exert uniform, controlled pressure on the tissue.

Technical Specifications:

• Model: KOCHER Retractor with Hammer Handle (Ultimate Preservation Model)

• Material: High-strength surgical premium stainless steel 1.4435 / 316LVM
• Surface: High-gloss polished, electropolished, and passivated for minimal adhesion
• Processing: Autoclavable up to 135°C. Mandatory: Manual pre-cleaning + validated cleaning-disinfection process.
• Special Feature: Most advanced instrument for biomedically optimized area retraction
• Risk Class: I according to Regulation (EU) 2017/745 (MDR)

Fields of Application (Highly Specialized):

• Microvascular reconstructive surgery with large flap procedures (e.g., DIEP, Latissimus flaps)
• Function-preserving tumor resections in orthopedics with nerve and vessel preservation
• Complex revision spinal surgery focusing on preservation of back extensor muscles
• Special trauma surgery in critical soft tissue conditions (e.g., open fractures grade III)
• Highly specialized procedures in plastic-reconstructive facial surgery

CRITICAL NOTES AND SAFETY PROTOCOLS:
• FOR USE BY HIGHLY QUALIFIED SURGEONS WITH EXPERTISE IN BIOLOGICAL AND TISSUE-PRESERVING SURGERY ONLY.
• INSTRUMENT FOR SPECIFIC INDICATIONS: Not for routine procedures. Use must be strictly indicated.
• PRE-OPERATIVE INSPECTION MANDATORY: Before each use, all eight prongs must be inspected under magnifying loupes for perfect geometry, free tips, and structural integrity. A single inadequate prong compromises the entire pressure profile.
• APPLICATION TECHNIQUE: Requires a special, almost flat application technique and measured, vertical traction. No rotational or prying movements.
• REPROCESSING PROTOCOL: Strictest hygiene. After manual pre-cleaning of spaces between prongs, automated cleaning/disinfection in an instrument tray with individual holder is mandatory. Regular inspection by instrument service.
• DISCARD POLICY: Upon the slightest signs of wear, polish alteration, micro-bending, or corrosion, the instrument must be immediately locked and returned to the manufacturer for assessment and specialized maintenance. No user maintenance possible.
