System for myomectomy and morcellation

摘要

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.

1. A method for dissecting a myoma from a uterine wall, the method comprising:
inserting a myomectomy screw retractor into a surgical site; articulating a tool assembly positioned at a distal portion of the myomectomy screw retractor relative to the myomectomy screw retractor such that a screw of the tool assembly is positioned adjacent to a myoma orthogonal to a 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 at least one of pitching, rotating, and providing traction to the myoma to expose cutting planes; and dissecting the myoma from the uterine wall by cutting along the exposed cutting planes; engaging an outer surface of the myoma positioned about the screw with a cutting tube of a morcellator including an elongated tube defining a second longitudinal axis and having the cutting tube disposed coaxially within a sheath at a distal portion of the elongated tube such that the screw is perpendicular to the second longitudinal axis; and activating the cutting tube such that the cutting tube morcellates the myoma by drawing a strip of tissue from the outer surface of the myoma, a screw synchronizer of the myomectomy screw retractor in communication with a morcellator synchronizer such that the screw is rotated in cooperation with the activation of the cutting tube to continuously feed tissue from the outer surface of the myoma to the cutting tube.
