A method for dissecting a myoma from a uterine wall includes inserting a myomectomy screw retractor into a surgical site, articulating a tool assembly positioned at a distal end of the myomectomy screw retractor such that a screw of the tool assembly is positioned adjacent to the myoma orthogonal to the uterine wall, rotating the screw of the tool assembly into the myoma until the screw is substantially engaged with the myoma, manipulating the myoma by pitching, rotating, and/or providing traction to the myoma to expose cutting planes, and dissecting the myoma from the uterine wall by cutting along the exposed cutting planes.
