A surgical lifter adapted to engage and lift the skin from the underlying tissue to create a work space in which a surgeon can operate, includes an expandable lifter head comprising at least two blades pivotally connected for relative pivotal movement between a deployed position in which the blades are fanned out, and a collapsed position in which the blades overlap one another; and a lifter shaft adapted to extend through the skin to engage the lifter head inside the body. A method of engaging and lifting the skin from the underlying tissue to create a work space in which a surgeon can operate, includes the steps of introducing under the skin an expandable lifter head comprising at least two blades pivotally connected for relative pivotal movement between a deployed position in which the blades are fanned out to form a surface area to engage the inside surface of the skin, and a collapsed position in which the blades overlap one another to facilitate their insertion into, and removal from, the body; inserting the distal end of a lifter shaft through a puncture wound through the skin, and attaching the distal end of the shaft to the expandable lifter head; fanning out the blades of the expandable lifter head to their deployed position; and pulling the lifter shaft to pull the lifter head against the inside surface of the skin to lift the skin away from the underlying tissue.
