Title
(EN) TRANSILLUMINATION OF BODY MEMBERS FOR PROTECTION DURING BODY INVASIVE PROCEDURES
(FR) TRANSILLUMINATION DE PARTIES DU CORPS A DES FINS DE PROTECTION PENDANT LES INTERVENTIONS EFFRACTIVES
Abstract
(EN)
An apparatus and method for protecting a body member during a body intrusive procedure in a region adjacent the body member to be protected (14) includes infrared energy (18) introduced into a light guide (17) which is introduced into the body member to be protected; and visible light (2) is introduced into the region, either of the lights may be pulsed at the frame rate of a monitor (12) energized by a video camera (10) that receives light from such region, the camera being sensitive to infrared energy as well as visible light. In a furhter embodiment, infrared light is removed from the visible light and a polarizing filter may be employed to filter the light to the camera to reduce glare. A body member to be located or illuminated may be illuminated from one side and the location of the illuminator (112) detected by a probe (116) on the other side of the body member.
(FR)
Appareil et procédé de protection d'une partie du corps au cours d'une intervention effractive dans une zone voisine de la partie à protéger (14), comprenant de l'énergie infrarouge (18) introduite dans un conduit de lumière (17) lui-même introduit dans le partie à protéger, et une lumière visible (2) introduite dans la zone, l'une ou l'autre de ces lumières pouvant être pulsée en fonction de la fréquence d'image d'un écran de contrôle (12) relié à une caméra vidéo (10) captant la lumière en provenance de ladite zone, cette caméra étant sensible aussi bien à l'énergie infrarouge qu'à la lumière visible. Selon un autre mode de réalisation, la lumière infrarouge est éliminée de la lumière visible et un filtre polariseur est éventuellement utilisé pour filtrer la lumière captée par la caméra afin d'atténuer l'éblouissement. La partie du corps que l'on souhaite localiser ou éclairer peut être éclairée depuis un côté de la partie en question, et l'emplacement de l'illuminateur (112) peut être détecté par une sonde (116) de l'autre côté de ladite partie.
