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.
The Doyen Periosteal Raspatory Right is part of the Fizza Surgical instrument catalogue, manufactured under ISO 13485:2016.
