Title (EN) TRACHEOSTOMY METHOD AND APPARATUS
(FR) PROCEDE ET DISPOSITIF DE TRACHEOTOMIE
Abstract:
(EN) Percutaneous tracheostomy. The trachea is penetrated by a hollow needle and a guide wire (43) is inserted into the trachea through the needle. The needle is removed leaving the wire (43) in the trachea. An instrument specifically adapted for use in tracheostomy operations, having two jaws (8) each with a groove (6) which cooperate when the jaws (8) are closed to form a passage, is inserted into the trachea opening with the guide wire (43) extending through the passage. The instrument is opened after insertion to widen the trachea opening. The instrument jaws (8) are curved so that when they are inserted into the trachea and spread to dilate the opening there is minimal risk of damage other than in the region of dilation. A tracheostomy tube is inserted into the opening via the wire (43) and the wire is withdrawn.
(FR) Trachéotomie percutanée. La trachée est pénétrée par une aiguille creuse et un fil de guidage (43) est inséré dans la trachée au travers de l'aiguille. L'aiguille est retirée en laissant le fil (43) dans la trachée. Un instrument spécifiquement adapté pour utilisation en trachéotomie, possédant deux pinces (8), chacune avec une gorge (6), coopérant quand elles (8) sont fermées pour former un passage, est inséré dans l'ouverture de la trachée avec le fil de guidage (43) introduit dans le passage. L'instrument est ouvert après insertion afin d'élargir l'ouverture de la trachée. Les pinces (8) de l'instrument sont recourbées de manière qu'après insertion dans la trachée et écartement pour dilater l'ouverture, il y ait un minimum de risques d'endommager une zone autre que celle de dilatation. Un tube de trachéotomie est inséré dans l'ouverture par l'intermédiaire du fil (43) et celui-ci est retiré.
