<P>PROBLEM TO BE SOLVED: To indicate a lesion by an indicator for three-dimensional position detection without contacting. <P>SOLUTION: In the indicator for the three-dimensional position detection attached to the tip of a multi-joint arm (2) of a three-dimensional position detector, a plurality of laser beams (10a and 10b) are emitted from the head part (9) of the indicator (3) so as to cross at the front of the head part (9) and a target or a virtual tip is captured by the intersection (10c). Thus, the lesion or the virtual tip can be searched without contacting a patient (A), it is safe, the patient is not invaded, and the indicator is not easily contaminated and is kept clean even when it is repeatedly used. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
