Long, Atraumatic Deep Retractor for Sensitive Retraction in Confined Surgical Approaches
The JANSEN BLUNT RETRACTOR is a medical device of CE Class I according to ISO 13485:2016. This instrument combines the precise, narrow 3x3 design of the Jansen retractor with fully blunt prongs and a depth reach of 10.0 cm. It is specifically designed for tissue-sparing yet stable retraction of sensitive structures in deep and narrow surgical fields where sharp prongs would pose an unacceptable risk.
Product Highlights:
✔ Certified according to ISO 13485:2016
✔ CE marking Class I (Directive 93/42/EEC)
✔ Narrow, long construction for minimal space occupation
✔ Atraumatic, blunt 3x3 prongs for secure hold without tissue injury
✔ Significant length: 10.0 cm for gentle retraction at depth
✔ High-quality Stainless Steel 1.4301 – rust-proof and biocompatible
✔ Verified biocompatibility according to ISO 10993
✔ Precise spring mechanism with finely adjustable tension
✔ Sterilizable and reusable (autoclavable)
Advantages of the Jansen Blunt Retractor:
• Atraumatic Deep Retraction: Enables reaching and securely holding tissue in the deepest, most confined spaces (e.g., spinal canal, joint capsule) absolutely without risk of perforation or cutting. Essential for gentle spinal surgery.
• Precise Hold on Minimal Area: The three blunt prongs per side provide a concentrated yet tissue-friendly grip, ideal for retracting dura, nerve root sheaths, synovial tissue, or sensitive ligamentous structures.
• Optimal Visibility with Maximum Tissue Protection: The narrow design hardly obstructs the visual field, while the blunt prongs remain safe even in direct contact with neural or vascular structures.
• Critical in Microsurgery and Revision Surgery: The instrument of choice when retracting in scar tissue, after previous surgeries, or near implants without causing new injury.
• Proven in Pediatric Surgery and for Vulnerable Patients: Particularly suitable for more delicate tissue or patients at increased risk of scarring.
Technical Specifications:
• Model: JANSEN Retractor, blunt
• Type: Long, narrow, and atraumatic spring retractor
• Total Length: 10.0 cm
• Prongs: Symmetrical, fully blunt and polished; 3 prongs on each side (3x3)
• Material: Stainless Steel 1.4301 (high-gloss polished)
• Mechanism: High-quality spring for sensitive tension adjustment
• Special Feature: Premium instrument for atraumatic deep retraction in Neurosurgery, Spinal Surgery, and Reconstructive Surgery
• Risk Class: I according to Directive 93/42/EEC
• Reprocessing: Fully autoclavable; smooth surfaces facilitate cleaning
Areas of Application:
• Atraumatic Spinal Surgery: Microdiscectomies, decompressions, revision surgeries near the dura
• Neurosurgical procedures with protection of neural structures
• Reconstructive joint surgery (e.g., shoulder, knee) for retraction of capsular tissue
• Hand surgery and tendon surgery
• Pediatric orthopedic and surgical procedures
• All deep approaches in scar tissue or post-radiation tissue
Important Safety Notes:
• FOR USE BY SPECIALIZED PERSONNEL WITH EXPERIENCE IN ATRAUMATIC SURGERY ONLY.
• Careful Pre-Use Inspection: Before each use, it must be ensured that all 6 prong tips are absolutely blunt, smoothly polished, and free of any nicks or edges. The long shaft must not show any bending.
• Despite blunt prongs, utmost caution is required: The concentrated force of the three prongs can cause pressure damage to neural tissue even without sharp edges if excessive pressure is applied. Spring tension must be minimal and always under control.
• Special sensitivity is required when retracting directly on the dura mater or in the area of nerve roots.
• The slender construction requires delicate handling. Lateral bending forces should be avoided.
• Replace immediately upon even minor changes in prong shape, polish, or if spring function is impaired.
