MEDICAL NEEDLE PATH DISPLAY

摘要

A system for facilitating manual alignment of a needle with a planned path of insertion includes first and second cameras supported in fixed spaced relation by a frame such that the optical axes of the cameras form between them an angle of more than 30 degrees, and preferably roughly 90 degrees. A processing system generates video displays for both cameras. A line in each of the video displays corresponding to an input planned path of insertion is determined, and a visual indication of that line is generated on the video displays.

1. A system for facilitating manual alignment of a needle with a planned path of insertion, the system comprising:
(a) a first camera having a first field of view and a first optical axis; (b) a second camera having a second field of view and a second optical axis; (c) a frame supporting said first and second cameras in fixed spaced relation such that said first and second optical axes form between them an angle of more than 30 degrees and such that said first and second fields of view overlap; (d) a display screen arrangement comprising at least one screen; and (e) a processing system comprising at least one processor, said processing system being in communication with said first and second cameras to receive video data and in communication with said display screen arrangement to generate a first display displaying video from said first camera and a second display displaying video from said second camera, wherein said processing system is configured to:
(i) input data defining a planned path of insertion;(ii) determine a line in each of said first and second fields of view corresponding to the planned path of insertion; and(iii) generate a visual indication of said line in both said first and said second displays.
