An interactive system for guiding the use of a surgical tool uses at least one imaging technique, such as CT scanning. A mechanical arm has a fixed base at a first end and a tool holder that holds the surgical tool at a second end. A display displays one or more images from the image space of a patient\s anatomy. A computer is coupled to the display and the mechanical arm. The computer tracks the location of the surgical tool through physical space, performs a transforming rotation of the physical space to the image space, and causes the display to display the location of the surgical tool within the image space.
A mechanical arm that is manipulable by a human operator, with the movement of the arm being trackable by a computer coupled to the arm, comprising: a base that is fixable to a surface; a first pair of joints coupled to said base; a first arm link coupled at a first end to the first pair of joints a
A mechanical arm that is manipulable by a human operator, with the movement of the arm being trackable by a computer coupled to the arm, comprising: a base that is fixable to a surface; a first pair of joints coupled to said base; a first arm link coupled at a first end to the first pair of joints and having two degrees of freedom provided by said first pair of joints; a second pair of joints coupled to a second end of said first arm link; a second arm link coupled to a first end to the second pair of joints and having four degrees of freedom provided by said first and second pairs of joints; a third pair of joints coupled to a second end of said second arm link; a tool holder coupled to said third pair of joints and having six degrees of freedom provided by said first, second and third pairs of joints; a separate encoder coupled to each joint that electrically encodes movement of a joint relative to another joint and produces signals indicating the amount and direction of movement of the joint; and wherein each of said arm links has a longitudinal axis, said pairs of joints define axes of rotation for adjoining arm links, and each of said axes of rotation is free to assume an orientation that is not parallel to the longitudinal axis of either of said adjoining arm links.
