US 2010/0305580 A1 · Instrument Guide System

Abstract

A system is provided to align a surgical guide instrument over a burr hole in a patient's body. Adjustments of a surgical instrument can be made in x, y, z, and angular directions using the system. An instrument guide unit can include an instrument guide for guiding a surgical instrument into the body of a patient and a base unit operative to be secured to the body near an area in which surgery is to occur. The base unit is coupled to the instrument guide. An adjustment mechanism, coupled to the base unit and the instrument guide, is operative to adjust the instrument guide in lateral directions with respect the surface of the area.
