High-Stability Volume Retractor for Powerful Soft Tissue Retraction in Orthopedics, Traumatology and Reconstructive Surgery
The KADER RETRACTOR 40 mm / 27.0 cm is a Class I medical device manufactured according to ISO 13485:2016. With a large hook diameter of 40 mm, this instrument is designed for powerful and secure retraction of massive soft tissue such as muscle, fascia, and scar tissue. Its robust construction allows for application under higher traction forces, as required in orthopedics and traumatology.
Product Highlights:
✔ Manufactured in accordance with ISO 13485:2016
✔ CE Marked – Class I (Regulation (EU) 2017/745 – MDR)
✔ Large-volume, solid hook head (Ø 40 mm) for maximum grip during demanding soft tissue retraction
✔ Optimal lever length of 27.0 cm for powerful and controlled handling
✔ High-quality, high-strength surgical stainless steel 1.4301 – for extreme stability and durability under load
✔ Fully rounded, high-gloss polished hook inner surface for atraumatic tissue contact
✔ Heavily reinforced shaft and solid hook-shaft junction to prevent bending
✔ Ergonomic, large finger ring for secure grip even with surgical gloves
✔ Satin finish for glare-free visibility
✔ Sterilizable and designed for long-term use
Benefits of the 40mm Kader Retractor:
• Excellent Holding Power for Large Soft Tissue Masses: The 40 mm hook provides a large contact area to securely and stably hold even powerful muscles (e.g., quadriceps, erector spinae).
• Ideal Instrument for Orthopedic Approaches: Specially suited for retracting muscle during total hip arthroplasty (e.g., anterolateral approach), knee, or shoulder surgeries.
• Reduced Risk of Tissue Tearing: The large, rounded hook surface distributes pressure evenly and minimizes point loading, which is especially important during lengthy operations.
• Highly Stable and Torsion-Resistant: Even under higher traction loads, the instrument remains shape-stable, allowing for controlled, safe surgery.
• Versatile in Traumatology: Optimal for retraction during the management of large soft tissue defects, open fractures, or in septic revision surgery.

Areas of Application:
• Orthopedic Joint Surgery (Hip, Knee, Shoulder)
• Trauma Surgical Management of Major Limb Injuries
• Orthopedic Tumor and Revision Surgery
• Reconstructive Soft Tissue Surgery with Large Access
• Procedures with Extensive Scar Tissue (e.g., Revision Surgeries)
Important Safety and Handling Information:
• FOR USE BY EXPERIENCED ORTHOPEDIC OR TRAUMA SURGICAL PROFESSIONALS ONLY.
• Powerful but Controlled Application: Although designed for higher forces, retraction force must be consciously dosed to avoid nerve compression or excessive tissue stretching.
• Placement Under Direct Vision: The large hook must be placed under direct vision to avoid unintentionally compressing neurovascular structures.
• Not a Levering Instrument: The instrument is not to be used as a lever or chisel substitute. This would lead to material fatigue and breakage.
• Regular Inspection: Before each use, inspect for material fatigue, cracks (especially at the hook-shaft junction), or bends.
• Intensive Cleaning: The large hook surface requires thorough cleaning after each use.
