Abstract: Cardiac surgery retractor which comprises a baseband formed by a first base and a second base, mutually arranged in a perpendicular manner and forming a cross-section of the baseband in the shape of an L, the second base being planar and the first base having a curved geometry; the baseband incorporating a fin formed by a profile with a cross-section also in the shape of an L and the fin being articulated at the second base of the baseband, at a lateral edge of the second base contiguous to the contact thereof with the first base of the same baseband; such that in one position of the joint of the fin, one of the sides of the L profile forming the fin is the continuation of the same second base and the other side of the same L profile of the fin is the continuation of the first base.

Abstract: Improved cardiac surgery retractor which comprises a baseband formed by a larger base and a smaller base, mutually arranged in a perpendicular manner and forming a cross-section of the baseband in the shape of an L, the smaller base being planar and the larger base having a curved geometry; the baseband incorporating a fin formed by a profile with a cross-section also in the shape of an L and the fin being articulated at the smaller base of the baseband, at a lateral edge of the smaller base contiguous to the contact thereof with the larger base of the same baseband; such that in one position of the joint of the fin, one of the sides of the L profile forming the fin is the continuation of the same smaller base and the other side of the same L profile of the fin is the continuation of the larger base.
