Abstract

Selon la présente invention, en fixant ce cylindre à une pince standard lors de la conduite d'une chirurgie endoscopique en utilisant de tels instruments en tant que laparoscope ou thoracoscope, et en plaçant ce cylindre derrière le tissu et en éclairant les vaisseaux sanguins de l'organe (estomac, gros intestin, intestin grêle, œsophage et similaire) ayant une lésion à réséquer, il est possible d'observer à travers les vaisseaux sanguins du tissu. Par conséquent, les vaisseaux sanguins de la lésion cible peuvent être déterminés plus précisément. Une fonction d'aspiration du cylindre aspire le sang, et le cylindre a en outre une fonction pour injecter un soluté physiologique et laver, et exclure et éviter un tissu. Avec cette configuration, la lésion cible peut être sûrement réséquée et le temps de résection peut être raccourci. Lors de la conduite d'une chirurgie endoscopique en utilisant de tels instruments en tant que laparoscope ou thoracoscope, ce cylindre (1) est fixé à une pince standard insérée dans un orifice d'insertion d'un laparoscope ou un thoracoscope. Le cylindre et la pince sont insérés dans la cavité abdominale ou la cavité thoracique et placés derrière l'organe cible, et en amenant des unités d'illumination (6, 7) à s'allumer, il est possible d'observer à travers des vaisseaux sanguins. En conséquence, l'emplacement de vaisseaux sanguins peut être précisément déterminé. Grâce à ces fonctions d'aspiration, d'injection, et d'exclusion, la chirurgie endoscopique peut être sûrement conduite.
