Abstract
This dissector can separate two structures by sliding atraumatically betweenthem. The shape of its distal tip (flattened), formed along a solid metalaxis, in the shape of a spoon (1) or a finger (with a curved tip) (19) oreven straight and flat (9), makes it easy to push the structure located inits concavity outward with no trauma to the structures.
Description

Dissecteur atraumatique à extrémité distale immobile et mousse (type cuillère) pour chirurgie sous videoscopie et endoscopique. Dissecteur atraumatique à extrémité distale immobile et mousse (type cuillère) pour chirurgie sous videoscopie et endoscopique.
Il s'agit d'un dissecteur utilisé en chirurgie endoscopique abdominale et thoracique, c'est à dire en chirurgie à ventre fermé et à thorax fermé sous controle videoscopique. Il peut être aussi utilisé lors de toute chirurgie abdominale ou thoracique avec abord minimum (ouverture) entrant dans le concept"Minimal Invasive Surgery".
Le dissecteur permet de séparer deux structures en se glissant de manière atraumatique entre celles-ci. La forme de son extrémité distale (aplatie), taillée dans la masse d'un axe metallique, en forme de cuillère ou d'un doigt (à l'extrémité incurvée) permet de repousser aisément la structure située dans sa concavité vers l'extérieur et cela sans traumatiser les structures.
Jusqu'à présent ce geste ne pouvait être effectué que par des ciseaux courbes ou droits, des pinces atraumatiques droites ou incurvées à extrémité distale fine. Ces instruments n'autorisaient pas de les repousser sans risque de les traumatiser vu leur conformation distale.
En effet, ces instruments, qu'ils soient fabriqués en 5mm. ou en 10mm. de diamètre, avaient tous une extrémité mousse mais fine qui faisait par ailleurs leur qualité pour certains usages.
Une membrane fine et tendue (comme un péritoine ou la surface externe d'un poumon) pouvait souvent être disse-

quée d'un organe voisin mais risquait d'être perforée si l'on se servait du même instrument pour les refouler. Il en est de même pour une paroi intestinale fine, une paroi d'oesoghage, un foie ou la plèvre...
Dans la technique antérieure il n'existait pas un instrument permettant de reproduire (à ventre fermé ou à thorax fermé) le travail de dissection douce qu'effectue souvent le chirurgien en se servant de l'extrémité de ses doigts et en refoulant les structures chargées par les doigts légèrement courbés (chirur gie conventionelle).
Ce dissecteur atraumatique est constitué d'une spatule (type bec de canard) dont l'extrémité est fine mais mousse et atraumatique de même que les coins de cet extrémité.
La partie de l'appareil utilisée pour faire la dissection, est creusée (1) dans l'axe cylindrique de l'appareil de telle sorte que l'extrémité distale prend la forme d'une cuillère (1) ou d'un doigt tendu recourbé (1) à son extrémité elle même plate mais mousse (8).
A ce niveau, des caractéristiques complémentaires peuvent être ajoutées (stries transversales (2), canal longitudinal (3) extrémité du"bec"crantée (4) mais atraumati- que...).
Ces dissecteurs peuvent être construits dans tous les diamètres permettant leur introduction dans des trocarts correspondants.
La longueur est variable et adaptée au type de patiënt (enfant/adulte) et à l'intervention réalisée (10 à 40cm...).
Détail de l'extrémité distale ; effilée, plate, mousse et lisse. Elle peut également être striée transversalement (2) afin de réaliser par frottement la séparation des deux structures anatomiques. Comme le fait le chirurgien au moyen de son doigt recouvert d'une compresse de gaze réalisant ainsi un ensemble (doigt-compresse) atraumatique mais agrippant malgré tout les structures anatomiques sans
<Desc/Clms Page number 3>
glisser.
Un canal longitudinal (3) peut être creusé au centre du bec distal. Une structure anatomique longitudinale peut ainsi glisser librement alors que les éléments environnants sont refoulés par la partie striée (2).
Des encoches multiples (4) peuvent être réalisées à l'extrémité du bec permettant d'empêcher le glissement du bord d'un élément anatomique plat ou arondi mais fin.
La forme générale distale de l'instrument en cuillère dégage de plus la région dissequée agrandissant ainsi le champ de vision de cette région.
Le fonctionnement du dissecteur a été décrit en faisant référence aux éléments qui le constituent (chiffres entre parenthèses faisant référence aux différents composants de l'appareil). Les dessins annexés sont donnés à titre d'exemples non limitatifs.

L'appareil décrit peut être en acier inox entièrement ou en partie. En effet un instrument métallique (lavable et restérilisable) pourrait également donner lieu à une production d'un instrument fonctionellement identique composé de matière non-métallique. Cet instrument entrerait alors dans le cadre de l'équipement à usage unique (disposable).

Atraumatic dissector with immobile distal end and foam (spoon type) for videoscopic and endoscopic surgery. Atraumatic dissector with immobile distal end and foam (spoon type) for videoscopic and endoscopic surgery.
It is a dissector used in abdominal and thoracic endoscopic surgery, that is to say in closed belly and closed chest surgery under videoscopic control. It can also be used during any abdominal or thoracic surgery with a minimum approach (opening) falling within the concept "Minimal Invasive Surgery".
The dissector makes it possible to separate two structures by sliding atraumatically between them. The shape of its distal end (flattened), cut in the mass of a metallic axis, in the shape of a spoon or a finger (at the curved end) allows to easily push the structure located in its concavity outwards and this without traumatizing the structures.
Until now this gesture could only be carried out by curved or straight scissors, straight or curved atraumatic forceps with fine distal end. These instruments did not allow them to be repelled without risk of traumatizing them given their distal conformation.
Indeed, these instruments, that they are manufactured in 5mm. or in 10mm. in diameter, all had a foam but fine end which also made their quality for certain uses.
A thin, tight membrane (like a peritoneum or the outer surface of a lung) could often be dis-
<Desc / Clms Page number 2>
qué from a neighboring organ but risked being perforated if one used the same instrument to repress them. It is the same for a thin intestinal wall, a wall of esoghage, a liver or the pleura ...
In the prior art, there was no instrument allowing to reproduce (with closed stomach or closed chest) the gentle dissection work that the surgeon often performs by using the end of his fingers and pushing back the charged structures. by slightly curved fingers (conventional surgery).
This atraumatic dissector consists of a spatula (duckbill type) whose end is fine but foam and atraumatic as are the corners of this end.
The part of the device used to make the dissection is hollowed out (1) in the cylindrical axis of the device so that the distal end takes the form of a spoon (1) or a stretched finger curved (1) at its end itself flat but foam (8).
At this level, additional characteristics can be added (transverse ridges (2), longitudinal channel (3) end of the notched "beak" (4) but atrauma ...).
These dissectors can be constructed in all diameters allowing their introduction into corresponding trocars.
The length is variable and adapted to the type of patient (child / adult) and to the intervention performed (10 to 40cm ...).
Detail of the distal end; tapered, flat, foam and smooth. It can also be striated transversely (2) in order to achieve by friction the separation of the two anatomical structures. As the surgeon does with his finger covered with a gauze pad thus achieving an atraumatic set (finger-pad) but still gripping the anatomical structures without

slide.
A longitudinal channel (3) can be dug in the center of the distal beak. A longitudinal anatomical structure can thus slide freely while the surrounding elements are pushed back by the striated part (2).
Multiple notches (4) can be made at the end of the beak to prevent sliding of the edge of a flat or rounded but thin anatomical element.
The general distal shape of the spoon instrument also releases the disseous region, thus enlarging the field of vision of this region.
The operation of the dissector has been described with reference to the elements which constitute it (figures in brackets referring to the various components of the device). The accompanying drawings are given by way of nonlimiting examples.
These are listed below: Fig. 1: Side view of the instrument (in full, spoon-shaped spout) (1).

The device described can be made of stainless steel in whole or in part. Indeed a metallic instrument (washable and re-sterilizable) could also give rise to a production of a functionally identical instrument composed of non-metallic material. This instrument would then be part of the disposable (disposable) equipment.
