Surgical retractor (6), designed in particular for minimally invasive operations, comprising an elastic plate (12) rolled up about an axis so as to form the side wall of a substantially truncated cone shape, the narrowest cross section (16) of the truncated cone constituting the distal part of this retractor, when the retractor is in place, and delimiting an operating field, the widest cross section (20) of the truncated cone forming the proximal part, through which instruments can be introduced, said plate (12) being able to be rolled up into a substantially cylindrical shape with a diameter smaller than or equal to the narrowest cross section of its truncated cone shape.
