Abstract

The multi-channel laser-video probe for diagnosis and treatment comprises a distal end formed by four independent inlet systems permitting access to four linear channels delimited within the body of the probe by four internal partitions. The introduction systems and the channels in the body of the probe are connected at the level of the base of the body of the probe. The length of the probe is variable, and its external diameter is very small, for example equal to 7 Fch or even smaller. This multi-channel structure permits the simultaneous use, if appropriate, of a sequenced optical fibre of very small diameter transmitting images, a laser fibre of very small diameter, a guide wire of very small diameter, and an irrigation line.

NOUVEAU CONCEPT D'UNE SONDE MULTICANALAIRE
VIDEO-LASER A VISE ES DIAGNOSTICS OU DE
TRAITEMENTS ENDOSCOPIQUES.NEW CONCEPT OF A MULTICHANNEL PROBE
VIDEO LASER AIMED AT DIAGNOSTICS OR
ENDOSCOPIC TREATMENTS.

DESCRIPTIF
Le diagnostic et le traitement endoscopique des lithiases, tumeurs et affections congénitales ou autres sous contrôle vidéoscopique par laser est effectivement réalisable aujourd'hui.DESCRIPTION
The diagnosis and endoscopic treatment of lithiasis, tumors and congenital or other ailments under videoscopic control by laser is actually feasible today.

La présente invention est un procédé et un nouveau concept qui permet traitements endoscopique et diagnostique. L'invention consiste en une sonde multicanalaire pour l'utilisation concomittante ou non d'une fibre optique ordonnée transmettant des images vidéo de très petit diamètre par exemple de 600 microns ou inférieur même, d'une fibre laser de très petit diamètre par exemple de 320 microns ou inférieur même, d'un fil guide de très petit diamètre, par exemple de 0,028 ou inférieur même et d'un canal d'irrigation.The present invention is a method and a new concept which allows endoscopic and diagnostic treatments. The invention consists of a multichannel probe for the concomitant use or not of an ordered optical fiber transmitting video images of very small diameter for example of 600 microns or even less, of a laser fiber of very small diameter for example of 320 microns or even less, a guide wire of very small diameter, for example 0.028 or even less and an irrigation channel.

La sonde est composée de matériaux biocompatibles (exemple = PVC, silicone...) rendu radio-opaque et son diamètre extérieur adapté par exemple inférieur ou égal à 7 French Charrière. L'extrémité distale de la sonde est composée de 4 systèmes d'entrées séparées et individuelles:
- une entrée pour la fibre laser (1, Fig.1/2)
- une entrée pour la fibre optique ordonnée transmettant des images video
(2, Fig. 1/2)
- une entrée pour le fil guide (3, Fig. 1/2)
- une entrée pour l'irrigation (4, Fig. 1/2) qui peut être muni d'un robinet d'arrêt.The probe is made of biocompatible materials (example = PVC, silicone ...) made radiopaque and its outside diameter adapted for example less than or equal to 7 French Charrière. The distal end of the probe is made up of 4 separate and individual input systems:
- an input for the laser fiber (1, Fig. 1/2)
- an input for the ordered optical fiber transmitting video images
(2, Fig. 1/2)
- an entry for the guide wire (3, Fig. 1/2)
- an inlet for irrigation (4, Fig. 1/2) which can be fitted with a stopcock.

La longueur de la sonde est variable suivant la destination thérapeutique ou diagnostique envisagée.The length of the probe is variable depending on the intended therapeutic or diagnostic destination.

Le corps de la sonde (6, Fig. 1/2) est de forme arrondie ou autres de façon à être le mieux adapté à l'utilisation souhaitée.The body of the probe (6, Fig. 1/2) is of rounded or other shape so as to be best suited to the desired use.

La lumière interne de la sonde est divisée par 4 cloisons de refend (8, 9, 10, 11
Fig. 2/2) disposées linéairement et parallèles au grand axe de la sonde de façon à réaliser 4 canaux distincts (1, 2, 3, 4 Fig. 2/2). Chaque canal fait suite à un des systèmes d'entrée précédemment décrits. Le raccordement entre le système d'entrée et son canal spécifique se fait au niveau de la base du corps de la sonde (5 Fig. 1/2).The internal lumen of the probe is divided by 4 partition walls (8, 9, 10, 11
Fig. 2/2) arranged linearly and parallel to the major axis of the probe so as to produce 4 separate channels (1, 2, 3, 4 Fig. 2/2). Each channel follows one of the input systems previously described. The connection between the inlet system and its specific channel is made at the base of the probe body (5 Fig. 1/2).

L'extrémité distale de la sonde p, Fig. 1/2) peut avoir une section bisaut.ne ou toute formes homothétiques ou ces formes déduites de ces homothéties par translation, rotation ou translation rotation associée d'un ou de plusieurs éléments de la figure 2/2. The distal end of the p probe, Fig. 1/2) can have a bisaut.ne section or any homothetic forms or these forms deduced from these homotheties by translation, rotation or associated translation rotation of one or more elements of figure 2/2.

L'extrémité du canal conducteur de la fibre laser est située au niveau de l'extrémité distale de la sonde 7, (Fig. 1/2) en position 1 (Fig. 2/2) aboutissant à l'extrémité de cette sonde.The end of the conductive channel of the laser fiber is located at the distal end of the probe 7, (Fig. 1/2) in position 1 (Fig. 2/2) leading to the end of this probe.

L'extrémité du canal irrigateur est située au niveau de l'extrémité distale de la sonde 7 (Fig. 1/2) en position 4 (Fig. 2/2) aboutissant à l'extrémité de cette sonde.The end of the irrigator channel is located at the distal end of the probe 7 (Fig. 1/2) in position 4 (Fig. 2/2) leading to the end of this probe.

L'extrémité du canal conducteur de la fibre optique est située au niveau de l'extrémité distale de la sonde 7 (Fig. 1/2) en position 2 (Fig. 2/2) aboutissant à l'extrémité de cette sonde. The end of the conductive channel of the optical fiber is located at the distal end of the probe 7 (Fig. 1/2) in position 2 (Fig. 2/2) leading to the end of this probe.

L'extrémité du canal conducteur du fil guide est situé au niveau de l'extrémité distale de la sonde 7 (Fig. 1/2) en position 3 (Fig. 2/2) aboutissant à l'extrémité de cette sonde. The end of the guide channel of the guide wire is located at the distal end of the probe 7 (Fig. 1/2) in position 3 (Fig. 2/2) leading to the end of this probe.

La sonde multicanalaire peut être utilisée avec ou sans l'aide de tout moyen endoscopique existant présentement ou devant être inventé.The multichannel probe can be used with or without the help of any endoscopic means presently existing or to be invented.

APPLICATIONS
La sonde multicanalaire peut être utilisée avec ou sans l'aide d'un système endoscopique existant ou devant être créé sous anesthésie locale, loco-régionale ou générale. La fibre laser peut être remplacée par tous autres procédé permettant de coaguler ou de sectionner dans la mesure où son diamètre extérieur est compatible avec le diamètre intérieur de l'un ou l'autre des canaux. La sonde multi-canalaire permet le traitement et le diagnostic des lithiases, tumeurs et affections congénitales ou autres. APPLICATIONS
The multichannel probe can be used with or without the help of an existing endoscopic system or to be created under local, loco-regional or general anesthesia. The laser fiber can be replaced by any other process making it possible to coagulate or to section insofar as its outside diameter is compatible with the inside diameter of one or other of the channels. The multi-canal probe allows the treatment and diagnosis of lithiasis, tumors and congenital or other ailments.
