Abstract

This is an apparatus for measuring the depth of destruction by vaporisation (photodesiccation) of the human tissue by CO2 laser. The measurement apparatus comprises: A manual probe with a flexible electrical contactor E; A sensor case with electronic display and holder; The holder contains the batteries of the electronic data collection and display system; A transmission system. The probe is manipulated by the user of the CO2 laser on the target organ to be treated. The treatment and the measurement are carried out with colposcopic observation. We have successfully used this in the treatment of precancerous lesions of the uterine neck, the vagina and the vulva.

DESSICATION BY LASER C02
Introductory statement
The introduction in therapy of the use of
Laser C02 dates back to our experience in September 1979. (i)
We mainly treat precancerous lesions of the cervix, the C02 laser allows vaporization of pathological cells.

Nous connaissons parfaitement la filiation entre les lésions infectieuses chroniques (virales surtout), les lésions dysplasiques, les cancers in situ (C.I.S.) puis le cancer invasif du col utérin ou du vagin. We are fully aware of the connection between chronic infectious lesions (especially viral), dysplastic lesions, cancers in situ (C.I.S.) and then invasive cancer of the cervix or vagina.

Sur le plan thérapeutique, la condition déterminante du succès de l'application du laser C02 repose la connaissance de la profondeur d'une part et de la surface de photodessication de la lésion d'autre part. On the therapeutic level, the determining condition for the success of the application of the C02 laser rests on the knowledge of the depth on the one hand and of the photodessication surface of the lesion on the other.

Différents procédés (colposcopie - microhystéroscopie) permettent de préciser le type et l'extension de la lésion, en particulier dans le canal cervical. Different procedures (colposcopy - microhysteroscopy) make it possible to specify the type and extent of the lesion, in particular in the cervical canal.

Nous vous présentons sur un diagramme, 1 extension d'un cancer in situ du col utérin (pièce jointe). > E;l
La précision de la mesure doit être de l'ordre de 100 Microns pour la profondeur et du mm2 pour la surface.We present on a diagram, 1 extension of an in situ cervical cancer (attachment). >E; l
The accuracy of the measurement must be around 100 microns for the depth and mm2 for the surface.

Nous avons mis au point un appareil de mesure permettant la connaissance de la profondeur de destruction des tissus humains et donnant donc la sécurité et une remarquable efficacité pour le traitement des lésions précancéreuses.  We have developed a measuring device allowing the knowledge of the depth of destruction of human tissues and thus giving safety and remarkable efficiency for the treatment of precancerous lesions.

- a probe (1 diagram) - a sensor unit with electronic display and support (1 diagram) - a transmission system (1 diagram)
Using the device
The probe is manipulated by the user of the CO2 laser under colposcopic examination of the target organ.

Un contact sélesotrique de l'extrémité de la sonde E au niveau du cratère d'une part et d'une tige métallique avec la surface saine de l'épithélium T permet un affichage automatique sur le boitier capteur de la profondeur de destruction avec une précision de l'ordre de 100 microns. A selesotric contact of the end of the probe E at the level of the crater on the one hand and of a metal rod with the healthy surface of the epithelium T allows an automatic display on the sensor housing of the depth of destruction with precision of the order of 100 microns.

La surface est donnée par le calcul à l'aide du rayon donné par la tige millimétrée T perpendiculaire à la sonde captrice. The surface is given by calculation using the radius given by the millimeter rod T perpendicular to the sensing probe.

Les inventeurs ont réalisé un prototype qui est surtout utilisé dans le traitement des lésions précancéreuses du col utérin chez la femme.The inventors have produced a prototype which is mainly used in the treatment of precancerous lesions of the cervix in women.

La présente invention concerne un dispositif pour mesurer précisemment la profondeur des tissus humains par le laser C02. The present invention relates to a device for accurately measuring the depth of human tissue by the C02 laser.

Jusqu'à présent, la destruction des tissus humains par le laser C02 était contrôléepar une observation colposcopique Il est évident qu'une telle observa- tion entraîne une incertitude considérable. Up to now, the destruction of human tissue by the CO2 laser has been controlled by colposcopic observation. It is obvious that such observation results in considerable uncertainty.

Le dispositif permet donc d'obtenir la profondeur exacte de destruction des tissus, préscrite suivant la pathologie de la patiente. The device therefore makes it possible to obtain the exact depth of tissue destruction, prescribed according to the pathology of the patient.

Le dispositif se présente sous la forme d'une sonde manuelle, appliquée directement sur la lésion.

Figure img00030001
The device is in the form of a manual probe, applied directly to the lesion.
Figure img00030001

La languette (5) repose sur le bord supérieur de la cavité tandis que le piston (6), initialement en butée au moyen du ressort (7), rentre à l'intérieur du cylindre (8).  The tongue (5) rests on the upper edge of the cavity while the piston (6), initially in abutment by means of the spring (7), returns inside the cylinder (8).

Ce qui a pour but de déplacer un noyau à l'intérieur de bobines. Une variation de flux magnétique se produit et donne une grandeur électrique proportionnelle au déplacement du piston (6). The purpose of which is to move a core inside coils. A variation in magnetic flux occurs and gives an electrical quantity proportional to the displacement of the piston (6).

Cette information est ensuite traitée de manière à luire directement sur un afficheur, le déplacement de la tige. This information is then processed so as to shine directly on a display, the displacement of the rod.

Un système électronique détecte le positionnement correcte de la sonde. An electronic system detects the correct positioning of the probe.

En effet, le voltmètre est bloqué s'il n'existe pas les contacts languette (5 > - tissus ; extrémité piston (6) - tissus. Indeed, the voltmeter is blocked if there are no tongue contacts (5> - fabrics; piston end (6) - fabrics.

La figure 3 représente en coupe la sonde. Figure 3 shows in section the probe.

La figure 2 représente le boîtier ayant des dimensions de tordre de 3 cm d'épaisseur, de 7 cm de largeur et de 14 cm de longueur, ainsi qu'une sonde d'une longueur de 24 cm, et d'un diamètre de 14 mm.  Figure 2 shows the housing having twist dimensions of 3 cm thick, 7 cm wide and 14 cm long, as well as a probe with a length of 24 cm, and a diameter of 14 mm.

La dissociation du boîtier et de la sonde permet une manipulation plus aisée. The dissociation of the housing and the probe allows easier handling.

La longueur de la languette permet un appui correcte sur le tissu sain et également une mesure approximative du rayon de la lésion, afin de déterminer la surface de la lésion. The length of the tongue allows correct support on the healthy tissue and also an approximate measurement of the radius of the lesion, in order to determine the surface of the lesion.

La largeur de la languette et le faible diamètre du piston facilite l'observation colposcopique et le contrôle de la mesure. The width of the tongue and the small diameter of the piston facilitates colposcopic observation and control of the measurement.

La partie supérieure de la sonde est démontable d'une part, pour être stériliséeaprès chaque intervention et d'autre part, pour adapter différentes sondes suivant le domaine d'application. The upper part of the probe is removable on the one hand, to be sterilized after each intervention and on the other hand, to adapt different probes according to the field of application.

La fixation de la sonde est un système à baîllonnette. La rondelle élastique (9) permet de mettre en contact les ergots (10) avec la pièce (4), afin d'assurer un postionnement identique après chaque démontage.  The probe attachment is a bayonet system. The elastic washer (9) makes it possible to bring the pins (10) into contact with the part (4), in order to ensure identical positioning after each disassembly.
