Illumination device for cholecystectomy |
| abstract |
A system for aiding in the successful performance of laparoscopic cholecystectomy, by improving the optical identification of the elements of the bile duct system. The identification system utilizes the differential absorption of light in bile products, as compared with its absorption in blood based tissues. The bile bearing vessels can thus be distinguished optically from surrounding tissues and vessels. The region of the operation is imaged in the 600-700 nm range, where bile absorbs more strongly than blood, such that the bile-bearing vessels appear substantially darker than the surrounding tissues. The illuminated region is imaged by a laparoscopic camera system. The desired spectral region can be selected either by using illumination having that selected spectral range, or by using a camera sensitive to that spectral range. The spectral range can be selected by use of optical passband filters disposed either on the illuminating system or on the camera. |
