Abstract
Devices, systems, and methods for providing remote traction to tissue may include a grasper and a control element. The grasper may have a first jaw, a second jaw, a main body, and a first magnetic element. The control element may include a second magnetic element. The first and second magnetic elements may attract the grasper to the control element such that the grasper is oriented parallel, perpendicularly, or at an angle between parallel and perpendicular with respect to the control element and/or a body. In some instances, the grasper may include first and second magnetic elements and the control element may include third and fourth magnetic elements.
Claims19
A method for performing a surgical procedure, comprising:
- grasping tissue in a grasper;
- magnetically repulsing the grasper away from a control element across an abdominal wall;
- repositioning the grasped tissue by manipulating the grasper via a magnetic element of the control element;
- and
- magnetically attracting a proximal end and a distal end of the grasper toward the control element across the abdominal wall by aligning a longitudinal axis of the grasper substantially parallel to an interior surface of the abdominal wall by rotating the magnetic element relative to the control element.
A method for performing a surgical procedure, comprising:
- grasping tissue in a grasper;
- magnetically repulsing the grasper away from a control element across an abdominal wall;
- and
- repositioning the grasped tissue by manipulating the grasper via a magnetic element of the control element, wherein repositioning the grasped tissue comprises aligning a longitudinal axis of the grasper substantially parallel to a longitudinal axis of the control element by rotating the magnetic element relative to the control element, wherein manipulating the grasper comprises magnetically attracting a proximal end and a distal end of the grasper toward the control element.
A method for performing a surgical procedure, comprising:
- grasping tissue in a grasper;
- magnetically repulsing the grasper away from a control element across an abdominal wall;
- and
- repositioning the grasped tissue by aligning a longitudinal axis of the grasper substantially transverse to an interior surface of the abdominal wall via a magnetic element of the control element.
A method for performing a surgical procedure, comprising:
- grasping tissue in a grasper;
- magnetically repulsing the grasper away from a control element across an abdominal wall;
- repositioning the grasped tissue by manipulating the grasper via a magnetic element of the control element, wherein manipulating the grasper comprises magnetically attracting a proximal end and a distal end of the grasper toward the control element;
- repositioning the grasped tissue a second time by manipulating the grasper via the magnetic element, wherein manipulating the grasper comprises magnetically repulsing the distal end of the grasper away from the control element by aligning a longitudinal axis of the grasper substantially transverse to an interior surface of the abdominal wall by rotating the magnetic element relative to the control element.
