Abstract
A laparoscopic tool or minimally invasive device is augmented with a forward looking ultrasonic transducer that is processed to extract information regarding subsurface structures and to generate haptic, audio, or visual effects to provide relevant feedback to a user that is operating the tool. In one embodiment, the ultrasonic transducer detects the distance or depth of subsurface structures such as a luminal hollow structure or a tumor mass. In another embodiment, the ultrasonic transducer extracts tissue identification information, tissue stiffness, velocity, or other pertinent information regarding subsurface structures that is subsequently communicated to the operator as haptic, audio, and/or visual feedback. The ultrasonic transducer may be operable in one or more modes, including A-mode or Doppler mode.
