Patent number: 7162292Abstract: With the beam scanning probe system for surgery, a pointer indicating the observation point of a beam scanning probe is superimposed upon an image of a lesion to be operated on in the head which is obtained via a TV camera or a surgery microscope, and the superimposed image information is registered as such in an image recording device. With the beam scanning probe system for surgery, information of a cytological picture is also registered in the image recording device. With the beam scanning probe system for surgery, the image recording device registers the two image information in a paired fashion. Through this arrangement, the beam scanning probe system for surgery can smoothly locate, for a given cytological picture, a site of a tumor to be treated from which the picture was obtained, which will ease the operation.Type: GrantFiled: May 16, 2002Date of Patent: January 9, 2007Assignee: Olympus CorporationInventors: Wataru Ohno, Masaaki Ueda, Masahiko Kinukawa
