A surgical retractor designed for wounds and incisions located on curved areas of the body. The clamp assembly comprising the present surgical retractor comprises multiple hinges and other types of movable joints allowing it to be adjusted to any number of positions in order to conform to various areas of the body as well as wounds or incisions of different sizes. In particular, the clamp assembly can comprise hinges located in the middle of at least two of its sides allowing it to be bent into multiple angles both above and below the flat horizontal position allowed by nearly all existing surgical retractors. Multiple retracting hook assemblies can be mounted at various positions along the sides of the clamp assembly allowing the hook comprising each to hold tissue in a variety of positions as needed.
