Adjustable body penetrating blades of a min-retractor are inserted, closed together, into a small incision in an abdominal cavity, spread to widen the incision and a trocar tube is installed in the cavity by clamping between the blades enabling performance of a laparoscopic procedure in conjunction with other trocars inserted into other incisions. Rapid reversal of the laparoscopic procedure is achieved by moving the blades apart, releasing the trocar, and swinging distal ends of the blades apart expanding an inner operating window. A stand having a flexible positioning arm attached to the min-applicator maintains the min-retractor elevated after withdrawal of the trocar and loss of pneumoperitoneum pressure from insufflation. The blades of the mini-retractor gripping the tube of the trocar define between them a scalpel access opening to skin on respective opposite sides enabling enlargement of the incision with the retractor and trocar installed in the abdominal cavity.
