Abstract

Optical mandrel intended to perform tracheal intubations easily and in complete safety with visual monitoring. The intubation technique relating to the present invention is to introduce in advance, inside an intubation tube, an optical apparatus of small size (optical mandrel) which is rigid and bent at its end in order to preform the intubation tube and thus to perform in all cases the tracheal intubation in complete safety and while being able to see the vocal cords. The optical mandrel comprises a rigid stainless steel sheath 1 in which there is positioned an image guide optical system 2, at the periphery of which there is situated a light guide 3. The end of the optical mandrel 4 is bent and makes an angle of approximately 30 DEG with the principal axis of the mandrel. The stainless steel sheath 1 is coated with a plastic sheath 5 allowing easy sliding of an intubation tube 6. An objective 7 allows the image to be picked up and an eyepiece 8 allows the eye 9 to see it. The optical mandrel according to the invention is intended to facilitate tracheal intubations with visual monitoring and in complete safety. <IMAGE>

Description

La présente invention concerne un mandrin optique destiné à réaliser des intubations trachéales d'une façon aisée et en toute sécurité sous contrôle visuel. The present invention relates to an optical core for performing tracheal intubations of easily and safely under visual control.

Pour intuber un patient, il faut passer une sonde d'intubation en plastique souple entre les cordes vocales sans créer de traumatisme. To intubate a patient, it is necessary to pass a flexible plastic intubation probe between the vocal cords without creating trauma.

Comme chacun sait, les cordes vocales ne sont pas visibles en ouvrant la bouche, il faut soulever la langue, d'autre part le plan des cordes vocales forme un angle par rapport à l'axe de la bouche, ce qui entraîne la nécessité d'avoir une extrémité de sonde anguleuse pour pénétrer entre cel les-ci . As everyone knows, the vocal cords are not visible by opening the mouth, we must raise the tongue, the other terms of the vocal cords form an angle to the axis of the mouth, resulting in the need having one end of angular probe to penetrate between one cel.

Au cours de leur carrie'e, les Anésthésistes se trouvent soit dans l'impossibilité de pratiquer l'intubation trachéale de leur patient, soit de la pratiquer avec d'énormes difficultés et ceci pour les raisons Grincipales suivantes - Cou court de dispositions anatomiques particulières, ou - D'une déviation wthologique de la glotte. During their carrie'e, anesthesiologists are either unable to perform tracheal intubation their patient or to practice with great difficulty and for the following reasons Grincipales - Short neck specific anatomical arrangements or - a wthologique deflection of the glottis.

Cc-s difficultés peuvent entraîner chez le patient, des traumatismes allant de simples lésions du voile du palais ou du pharynx, à celles du larynx ainsi que des ovulsions et fractures dentaires. DC-s difficulties may result in the patient, trauma from simple lesions of the soft palate or pharynx, larynx those as well as ovulsions and dental fractures.

La technique d'ir.tubation actuellement appliquée par le praticien, est d'utiliser un laryngoscope qui permet de récliner la langue et ainsi de rendre visibles de l'extérieur les cordes vocales dans la majorité des cas, le pI#ticie# EssaJe ensuite d'introduire la la sonde d' intubation avec toutes les difficultés-et les risques encourus tels que ceux cités précedemment. The ir.tubation currently applied technique by the practitioner is using a laryngoscope which allows to retract the tongue and so make visible outside the vocal cords in the majority of cases, the pH # # ticie then EssaJe to introduce the intubation probe with all the difficulties and risks, such as those mentioned previously.

D'autres techniques d'intubations pourraient venir à l'esprit, en utilisant des instruments optiques tels que, l'endoscope rigide et le fibroscope souple. Other intubation techniques might come to mind, using optical instruments such as the rigid and flexible fiberoptic endoscope. Pour cette application, ces appareils présentent des inconvénients importants, ce qui les rend inutilisables; For this application, these devices have significant disadvantages, which makes them unusable; l'endoscope rigide est droit, donc ne permet pas de visualiser les cordes vocales et de préformer la sonde d'intubation avant son introduction, le fibroscope, sa souplesse ne permet pas de maintenir la sonde d'intubation, donc a fiortori de l'introduire. the rigid endoscope is right, so do not visualize the vocal cords and to preform the endotracheal tube before introducing the endoscope, flexibility does not maintain the endotracheal tube, so fiortori has the introduce.

la technique d'intubation concernant la présente invention est d'introduire au préalable à l'intérieur de la sonde d'intubation, un appareil optique de petite taille (mandrin optique) rigide, coudé à son extrémité afin de préformer la sonde et ainsi de réaliser dans tous les cas, l'in- tuba-tion trachéale en toute sécurité et en visualisant les cordes vocales. the intubation art relating to the present invention is to introduce beforehand inside the endotracheal tube, a small optical device (optical core) rigid, angled at its end in order to preform the probe and so achieve in all cases, the in- snorkel-ing tracheal safely and visualizing the vocal cords.

Une fois que la sonde est mise en placeS le mandrin optique se retire facilement Once the probe is placed in the optical core is easily removed
Le mandrin optique objet de l'invention, de par sa petite taille 4 à 6 mn de diamètre, permet de glisser autour de celui-ci la sonde d'intuba tion; The optical mandrel object of the invention, by its very small 4-6 nm in diameter, makes it possible to slide around thereof tion intuba probe; sa partie coudée à l'extrémité permet à la sonde d'être préformée, c' est-à-dire de prendre la forme du mandrin optique et ainsi de pouvoir être introduite dans la trachée en passant entre les cordes vocales sous contrôle visuel permanent et donc en toute sécurité. its bent portion at the end allows the probe to be preformed, that is to say to take the shape of the optical core and so be introduced into the trachea through between the vocal cords under continuous visual control and so safely.

La figure 1 représente le mandrin optique selon l'invention. Figure 1 shows the optical mandrel according to the invention.

Le mandrin optique selon la figure 1 comprend une gaine extérieure en acier inoxydable rigide d'un diamètre de 4 à 6 mrri et d'une longueur de de 250 à 300 mm environ (1) dans laquelle est installé un système optique de guide image (2) soit par lentilles, soit par fibres conductrices d'image, au pourtour duquel se situe un guide lumière (3) par fibre optique. The optical mandrel according to Figure 1 comprises an outer sheath of rigid stainless steel of a diameter of 4 to 6 mrri and a length of 250 to about 300 mm (1) in which is installed an optical image guide system ( 2) by lenses or by conductive fibers image, the periphery of which is a light guide (3) by optical fiber. L'extrémité du mandrin optique (4) est coudée sur une longueur de 20 à 50 mrn et fait avec l'axe principal du mandrin optique, un angle d'environ 300. The end of the optical core (4) is bent over a length of 20 to 50 mrn and made with the main axis of the optical core, an angle of about 300.

La gaine inox (1) est recouverte d'une gaine plastique (5) sur toute la longueur du mandrin optique permettant le glissement aisé de la sonde d'intubation (6). The stainless steel sleeve (1) is covered with a plastic sheath (5) over the entire length of the optical mandrel allowing easy sliding of the endotracheal tube (6). Un objectif (7) permet de capter l'image et un oculaire (8) permet de la restituer à l'oeil (9). A goal (7) captures the image and an eyepiece (8) allows the return to the eye (9).

Une connection (10) permet d'apporter la lumière d'une source extérieure qui est transmise à l'extrémité du mandrin par l'intermédiaire du guide lumière (3). A connection (10) allows to bring light from an external source which is transmitted to the end of the mandrel through the light guide (3).

Le mandrin optique selon l'invention est destiné à faciliter les intubations trachéales sous contrôle visuel et en toute sécurité. The optical core according to the invention is intended to facilitate the tracheal intubations under visual control and safely.
