Abstract

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.

First claim

What is claimed:

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.

2. The method according to claim 1 , further including extending a guide wire from a distal end of the screw into the myoma before rotating the screw.

3. The method according to claim 1 , wherein the myomectomy screw retractor is coupled at a proximal portion to a powered surgical instrument and wherein at least one of articulating, rotating, manipulating, and dissecting is performed via actuating the powered surgical instrument.

4. The method according to claim 1 , wherein the myomectomy screw retractor is coupled at a proximal portion to a robotic surgical system and wherein at least one of articulating, rotating, manipulating, and dissecting is performed via actuating the robotic surgical system.

5. The method according to claim 1 , wherein the morcellator includes a motion sensor, and wherein the cutting tube is deactivated when the motion sensor detects displacement of the cutting tube while the cutting tube is activated.

6. The method according to claim 1 , wherein at least one of the myomectomy screw retractor and the morcellator is an end effector attached at a proximal portion to a powered instrument and wherein at least one of articulating, rotating, manipulating, dissecting, engaging, and activating is performed via actuating the powered instrument.

7. The method according to claim 1 , wherein at least one of the myomectomy screw retractor and the morcellator is an end effector coupled at a proximal portion to a robotic surgical system and at least one of articulating, rotating, manipulating, dissecting, engaging, and activating is performed via actuating the robotic surgical system.
