| 摘要 |
The present invention has for its object a pre-operative device particularly for the location of tumors and a detection process using said device. Device characterized in that it comprises essentially, on the one hand, at least one elongated probe (1) integrating at least one means (2) for detecting radioactive radiation (3) emitted by tissues (4) marked by radioactive isotopes or radioactive colloids, generating a first representative electrical signal (5), at least one means (6) for emitting luminous radiation toward the tissues (4) and at least one means (7) for receiving and transmitting reflected luminous radiation (8) reflected by said tissues (4) marked by vital colorants or magnetic markers, toward at least one means (9) for converting said reflected luminous radiation (8) into a second representative electrical signal (10), on the other hand, electrical connection means for conveying said first and second electrical signals (5, 10) and, finally, at least one electronic means (11) for processing electronic signals (5, 10) conveyed by said means, for the display of a reconstituted image (12) of the tissues (4) marked by said colorants on a screen (13) or the like and simultaneously supplying a physically perceptible expression (12') of the first electrical signal (5).
