An apparatus for use in simulated image guided surgery comprises a
positional transducer, clamping means located proximate to the transducer,
and a processor. The transducer is responsive to a thin flexible member
that can be manipulated by a user, and produces signals representative of
displacement and rotation of the thin flexible member. The clamping means
responds to a controlling signal to apply a predetermined variable
clamping force to the flexible member. The processor receives these
displacement and rotation signals, and is programmed to plot the path of
the flexible member therefrom as it is manipulated by the user.
Additionally, the processor produces the controlling signal to the
clamping means in response to the instantaneous position along the path.
The processor may be coupled to a display device for displaying an image
of the instantaneous position of the flexible wire therealong, or other
information. The invention also includes a related method for the
simulation of image guided surgery. Embodiments of the invention can be
used to simulate the manual positioning of a catheter and guidewire, as
well as the haptic forces exerted by the user's hand and fingers in that
positioning, or can simulate the process of balloon angioplasty, including
stent deployment.
