Title:
DEVICE AND METHOD FOR GUIDING MEDICAL INSTRUMENT
Document Type and Number:
Japanese Patent JPH09192138
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To attach a mark to the expected guide route of a medical instrument such as a stitching needle or the like. SOLUTION: Two electromagnetic line sources 5A and 5B like lasers for generating two light beams are provided and the cross line of the light beams attaches the mark to the guide route of the stitching needle 10. The deviation of the angle position of the stitching needle 10 from the expected guide route is visually confirmed by the reflection of light from the stitching needle 10. The light of different colors is used and the light beams are formed in sectorial shapes 7 and 8 on a common surface. Thus, the color of reflected light on the surface of the stitching needle 10 is changed depending on whether or not the stitching needle 10 is present at the crossing part of the light beams.
