A surgical retractor comprising a body portion including: a first blade holder and a first blade detachably secured to the first blade holder; and first and second retractor arms (120, 130) operatively coupled to the body portion, characterized in that: the body portion comprises: a tube assembly comprising: a rotatable knob; the first blade holder operatively coupled with the rotatable knob such that rotation of the rotatable knob causes axial displacement of the first blade holder; the first blade being configured for axial displacement with the first blade holder and angulation relative to at least part of the body portion about a first toeing axis; and first and second mounting wings (118a, 118b) extending from opposing sides of the tube assembly; a first drive pin securing the first retractor arm to the first mounting wing, the first drive pin defining a first pivot axis (P 1) about which the first drive pin rotates to pivot the first retractor arm relative to the tube assembly and the second retractor arm; and a second drive pin securing the second retractor arm to the second mounting wing, the second drive pin defining a second pivot axis about which the second drive pin rotates to pivot the second retractor arm relative to the tube assembly and the first retractor arm; the first and second retractor arms including respective second and third blades (400a, 400b) detachably secured thereto, the first and second retractor arms transitionable between an approximated configuration in which the second and third blades are proximate each other, and a spaced apart configuration in which the second and third blades are spaced apart from each other, the second and third blades being further configured to angulate about respective second and third toeing axes (T 1, T2) that are defined by the respective first and second retractor arms. a body portion including: a first blade holder and a first blade detachably secured to the first blade holder;
