US 9,788,900 B2 · Surgical instrument positioning system and method

Abstract

A surgical instrument positioning system includes articulating arms for coarse adjustment and a micro manipulator connectable to the articulating arms for fine adjustment. The micro manipulator selectively holds the surgical instrument and is operable to adjust the position of the surgical instrument. The micro manipulator includes two adjustment assemblies for providing linear adjustment and two adjustment assemblies for providing rotational adjustment. Features of the system also provide for control of the amount of free movement or play within the micro manipulator. Also a stop feature works in conjunction with the adjustment assemblies to maintain the tip of the instrument at an intersection of the two rotational axes facilitating rotational adjustment of the micro manipulator without linear displacement of the instrument tip.
