Abstract
Abstract Surgical instrument, particularly a surgical retractor, for use in harvesting saphenous veins for use in coronary bypass operations. The retractor includes a handle, a retractor blade member including first and second limbs which define a view area axis, and a light source coupled to the retractor blade member for directing light away from the handle and away from the view area. The retractor may be inserted into a surgical wound to illuminate the surgical field. In use, the surgical retractor may be manipulated by a physician and can be used to expose sections of the vein and to facilitate blunt dissection along the length of the vein.
