Abstract

L'invention concerne un dispositif bi-polaire permettant la coupe et la coagulation. Il est constitué, par l'association constituant un ensemble indissociable de deux lames électrodes (1) en acier inoxydable avec une lame (2) en matière réfractaire les isolant entre elles tout en les rendant solidaires par soudage à chaud. Cet ensemble est inséré dans une monture constituée d'un tube en acier (8) inoxydable, contenant les fils d'alimentation (3) des lames électrodes, lui même incorporé dans un manche ergonomique (9) en matière autoclavable, recevant les connexions d'alimentation (4) électriques assemblées dans une douille (5) en acier inoxydable, supportant les lames de contact (6) isolées entre elles sur lesquelles est branché le cordon bi-polaire, reliant le crochet bistouri au générateur H.F.The invention relates to a bi-polar device for cutting and coagulation. It is formed by the association constituting an inseparable assembly of two electrode blades (1) made of stainless steel with a blade (2) of refractory material insulating them from one another while making them integral by hot welding. This assembly is inserted into a frame made of a stainless steel tube (8), containing the supply wires (3) of the electrode blades, itself incorporated in an ergonomic handle (9) in autoclavable material, receiving the connections of '' power supply (4) assembled in a socket (5) in stainless steel, supporting the contact blades (6) insulated from each other on which the bi-polar cord is connected, connecting the scalpel hook to the HF generator

Description

BISTOURI en MODE BI-POLAIRE à 2 ELECTRODES SOLIDAIRES ISOLEES POUR
L'ELECTROCHIRURGIE EN COELIOSCOPIE.
BISTOURI in BI-POLAR MODE with 2 SOLIDAR ELECTRODE ISOLATED FOR
ELECTROSURGERY IN CELIOSCOPY.

Actuellement la coagulation et la coupe par utilisation de crochet bistouri se Dratiauent au moYen d'un instrument dit mononolaire. ne comportant qu'une électrode. entrant en contact avec les tissus à traiter. connectés à une source électrique par l'intermédiaire d'une plaque métallique adhérent à l'éniderme du patient.Currently coagulation and cutting by use of a scalpel hook are done using a so-called mononolar instrument. having only one electrode. coming into contact with the tissues to be treated. connected to an electrical source via a metal plate adhering to the patient's skin.

Instrument et plaaue sont reliés à un générateur haute fréauence dit bistouri électriaue.Instrument and plate are connected to a high-frequency generator known as an electrosurgical knife.

Ce procédé utilisant le malade comme un câble conducteur de courant présente des dangers concrétisés par des lésions et plus gravement par des décés (40 recensés) dus à l'impossibilité à limiter l'action de 11 instrument au seul Doint de contact sans diffusion environnante et indésirable d'arc en dehors du champ de vision de l'optique. This process using the patient as a current conducting cable presents dangers concretized by lesions and more seriously by deaths (40 identified) due to the impossibility of limiting the action of the instrument to the sole contact point without surrounding diffusion and unwanted arc outside the field of vision of the optics.

-Les inconvénients signalés. limite l'usage du bistouri à la chirurgie digestive nécessitant toutefois un grand savoir faire. La chirurgie gynécologique l'exclut. A titre indicatif son usage est la deuxième cause de procés contre les gynécologistes des U.S.A. et est considéré comme n'étant tas sur. Par l'un des Dlus grands praticiens de la coe -liochirurgie. le Professeur SEMM.-The drawbacks reported. limits the use of the scalpel to digestive surgery, however requiring great know-how. Gynecological surgery excludes it. As an indication, its use is the second cause of lawsuits against gynecologists in the U.S.A. and is considered not to be heap on. By one of the Dlus great practitioners of coe -liosurgery. Professor SEMM.

L'instrument décrit ci-dessus permet de remédier au risque de trajet aléatoire du courant H.F. et de lésions thermiques ou électriques par la stricte localisation de son action au niveau des électrodes de contact.The instrument described above makes it possible to remedy the risk of random path of the H.F. current and of thermal or electrical lesions by the strict localization of its action at the level of the contact electrodes.

-Il supprime l'utilisation de là Plaque de contact transformant le patient en conducteur électrique. et regroupe en lui-même la bi-tol#risation.  -It eliminates the use of there Contact plate transforming the patient into an electrical conductor. and groups together bi-tol # rization.

Dar l'association de 2 électrodes solidaires bien au'isolées entre elles tar l'intertosition d'une lame isolante à haute résistance thermique. Dar the association of 2 solid electrodes well au'insulated between them tar the interposition of an insulating blade with high thermal resistance.

Les risaues encourus et son utilisation jusque là interdite en gynéco- -logie. pédiatrie et tour les Dorteurs de Diles cardiaaues ne sont Dlus des obstacles à un large usage tout en garantissant une sécurité absolue du malade.The risks involved and its use hitherto prohibited in gynecology. pediatrics and the Cardiac Dile Sleepers are not more than obstacles to wide use while guaranteeing absolute safety for the patient.

-La figure t représente le dispositif -t.es figures 2 et 3 retrésentent des variantes à ce dispositif -En référence à ces dessins l'instrument est constitué Dar -2 électrodes (z) en métal inoxydable à haut point de fusion soudées à chaud de Dart et d'autre d'une lame isolante (2) à haute résistance mécanique et thermique. le tout formant un ensemble solidaire et rigide de tvte lame unique pouvant affecter la forme d'un crochet ou -d'une spatule. -Figure t represents the device -t.es Figures 2 and 3 show variants of this device -Reference to these drawings the instrument consists of Dar -2 electrodes (z) made of stainless metal with high melting point hot welded of Dart and other of an insulating strip (2) with high mechanical and thermal resistance. the whole forming an integral and rigid assembly of a single blade head which can affect the shape of a hook or a spatula.

Les électrodes sont décalées longitudinalement et latéralement l'une
par rapport à l'autre afin d'éviter le pontage inévitable dans le cas
d'assemblage sur. le même alignement.
The electrodes are offset longitudinally and laterally one
relative to each other to avoid the inevitable bridging in the case
assembly on. the same alignment.

Ls plus avancée au contact des tissus amorce la mise sous tension. la
seconde crée l'arc.
The most advanced in contact with the tissues initiates tensioning. the
second creates the arc.

Chaaue électrode est soudée à un câble(3) conducteur aboutissant à une
douille démontable (5) et débranchable par fiche de connexion (4)
comportant deux lames en acier inoxydable (6) isolées entre elles par
une Plaque non conductrice (7) devant être connectées à un cordon
bi-polaire branché sur le générateur haute fréquence.
Each electrode is welded to a conductive cable (3) leading to a
removable socket (5) and removable by connection plug (4)
comprising two stainless steel blades (6) insulated from each other by
a non-conductive plate (7) to be connected to a cord
bi-polar plugged into the high frequency generator.

L'ensemble électrodes et fils. est inséré dans une gaine thermo rétrac
table pour être introduit dans un tube en acier inoxydable constituant
la tige de l'instrument (8) assortie d'un manche ergonomique (9) en
matiére isolante autoclavable dans lequel sont logés les contacts
démontables (4) de la douille bi-polaire (5).

table to be inserted into a stainless steel tube constituting
the stem of the instrument (8) with an ergonomic handle (9) in
autoclavable insulating material in which the contacts are housed
