DOYEN x = 30 mm , 180 g 195mm 19.5cm (Ref BS 14-40-02), manufactured at the Fizza Surgical facility in Sialkot, Pakistan.

Eugène-Louis Doyen, a French surgeon active in the late nineteenth and early twentieth centuries, contributed several instrument designs to the surgical canon. Doyen retractors come in two main types: the rib raspatory used in thoracic surgery to elevate the periosteum from a rib, and the abdominal retractor used during laparotomy. The rib raspatory pattern is asymmetric — left and right variants — with a curved blade that follows the rib’s profile. The abdominal Doyen has a broad curved blade that retracts viscera during exploration. Both patterns remain in use; the rib raspatory is a standard thoracic instrument used during open thoracotomy where minimally invasive approaches are not feasible.

Every instrument is forged, machined, and finished at the Sialkot facility from German-origin stainless billet — austenitic 304 / 316 grades for non-cutting, mucosal-contact, and hollow-ware lines where corrosion resistance is the priority, martensitic 420 / 440 grades for cutting and edge-retention patterns where heat-treatable hardness matters, and 17-4 PH precipitation-hardened stainless for high-load orthopedic and implant-handling applications. Polishing, passivation, and final inspection are performed in-house under documented quality procedures aligned with ISO 13485:2016.
