Abstract
A gastrocnemius knife and retractor system and kit includes a surgical knife and a soft tissue retractor. The soft tissue retractor is configurable to move from a collapsed mode to an expanded mode and back again, and can be inserted through a small incision when in the collapsed mode. Once inside the incision, the soft tissue retractor is expanded to permit visualization and accessibility of the surgery site. The surgical knife is then introduced and guided along a path in the frame of the soft tissue retractor, thereby incising the desired tissue. Once the tissue is incised, the surgical knife is withdrawn, followed by the soft tissue retractor after it is collapsed.
