A remote center positioner used to support an instrument and provide a center of spherical rotation, remote from any bearings or mechanical supports, at a desired location of the instrument. The remote center positioner is particularly useful in laparoscopic surgery to constrain a surgical instrument to move around a fixed center of rotation remote from any bearings or mechanical supports and coincident with an entry incision in the abdominal wall.
[ What is claimed is:] [1.] A surgical manipulator for moving an instrument about a desired spherical center of rotation at a desired fixed location along the instrument, the manipulator comprising:a base support adapted to be fixedly mounted to a surface;a first linkage, including at least a first
[ What is claimed is:] [1.] A surgical manipulator for moving an instrument about a desired spherical center of rotation at a desired fixed location along the instrument, the manipulator comprising:a base support adapted to be fixedly mounted to a surface;a first linkage, including at least a first rod, pivotally mounted on the base support for rotation about a first axis;an instrument holder holding the instrument in a position so that the desired remote center of spherical rotation of the instrument intersects a second axis perpendicular to and intersecting the first axis;a second linkage, including at least a second rod, pivotally connected to the first linkage and the instrument holder for moving the instrument holder in a parallel-plane relationship to the first linkage such that the spherical center of rotation is maintained at the desired fixed location along the instrument; andwherein at least one of the first and second linkages includes a flexible drive element comprising a pulley and a flexible element connected around the pulley, the pulley rotationally affixed to one of the rods such that a movement of one of the linkages is transmitted to the other of the linkages by the flexible drive element.
