TRILLAT 240 mm – Knee Retractors

The TRILLAT 240 mm – Knee Retractors (Ref KR 14-125-01) is part of the Fizza Surgical instrument catalogue, manufactured under ISO 13485:2016.

Self-retaining retractor frames removed one of the most fatiguing roles in open surgery — the assistant who held wound edges apart for hours of pelvic, abdominal, or thoracic work. The Balfour frame opens abdominal incisions with lateral blades and an optional bladder blade. The Bookwalter system anchors to the operating table with a horseshoe ring and accepts multiple interchangeable blades positioned around the wound edge. The Weitlaner and Gelpi serve superficial and orthopaedic exposures with sharp or blunt prongs locked by a ratchet on the cross-bar. Material requirements are demanding: the frame must resist deformation under sustained retraction load, which is why most self-retaining systems use AISI 440 or 17-4 PH precipitation-hardened stainless steel, while hand-held variants typically use AISI 304 austenitic stainless for corrosion resistance through repeated autoclave cycles. Fizza manufactures the full self-retaining range under ISO 13485:2016.

OEM private-label production is available from 300 units per SKU, with custom laser etching for distributor codes, hospital procurement IDs, and sterilization-cycle tracking marks. Custom packaging — peel pouch, blister, fabric-wrap kits, or co-branded boxes — is configured to distributor specification. Bulk-order pricing tiers are available on request for hospital group purchasing organizations and national procurement entities.
