Abstract

Forceps for medical and surgical uses, characterised in that they are obtained by moulding a flexible and elastic plastic into a strip which, in its central part, has a zone rounded according to an almost complete circle, so that its two branches return to intersect by means of two symmetrical indentations made towards their middle part, the ends of these branches having, in their mutually confronting faces, a concave shape corresponding to that of a blood vessel, to which the forceps are to be fitted.

Description

La présente invention concerne un instrument nouveau à usage médical, notamment dans le domaine de la médecine et de la chirurgie cardio-vasculaire. Cet instrument est constitué par une pince élastique se caractérisant par un certain nombre de particularités constructives qui en permettent essentiellement deux applications
- une première application comme support de conducteurs électriques reliés à un détecteur à ultra-sons de corpuscules véhiculés dans la circulation sanguine, tel que décrit dans le brevet français 76/34550
- une seconde application comme pince aortique, dans la pratique des opérations chirurgicales dites 11a coeur ouvert".
The present invention relates to a new instrument for medical use, in particular in the field of medicine and cardiovascular surgery. This instrument is constituted by an elastic clamp characterized by a certain number of constructive features which allow essentially two applications.
- a first application as a support for electrical conductors connected to an ultrasonic detector of corpuscles conveyed in the blood circulation, as described in French patent 76/34550
- a second application as an aortic forceps, in the practice of surgical operations known as 11a open heart ".

L'essentiel de ces particularités constructives réside dans le fait que ledit instrument est monté en une seule bande en matière plastique souple et élastique, cette bande présentant dans sa partie centrale une zone arrondie sur un cercle presque complet de manière à ce que ses deux extrémités reviennent se croiser grâce à deux échancrures symétriques pratiquées vers leur partie médiane, lesdites extrémités présentant une forme concave adaptée à celle d'un vaisseau sanguin, de manière à exercer normalement sur lui une action s'adaptant à la physiologie de l'adulte et/ou de l'enfant et à s'en écarter en le libérant quand ladite partie arrondie subit une légère pression de déformation vers l'intérieur. The essential of these constructive features lies in the fact that said instrument is mounted in a single strip of flexible and elastic plastic material, this strip having in its central part a rounded area on an almost complete circle so that its two ends come back to cross thanks to two symmetrical notches practiced towards their middle part, said ends having a concave shape adapted to that of a blood vessel, so as to normally exert on it an action adapting to the physiology of the adult and / or of the child and to deviate from it by releasing it when said rounded part undergoes a slight pressure of deformation inward.

L'instrument joue ainsi le rôle d'une pince--que l'on peut ouvrir par une légère action seulement exercée sur une zone éloignée de la zone de pincement proprement dite. The instrument thus plays the role of a clamp - which can be opened by a light action only exerted on an area remote from the nipping area proper.

Dans le cas de l'application à la détection et au comptage de corpuscules tels que des bulles gazeuses dans le sang circulant dans un vaisseau sur lequel est placé la pince, des conducteurs sont logés dans les extrémités des deux branches entourant le vaisseau. De préférence les conducteurs sont noyés dans des pièces de matière plastique venant s'adapter dans des logements correspondant pratiqués dans ces extrémités, ce qui en facilite la pose et la dépose sans déplacer la pince. In the case of application to the detection and counting of corpuscles such as gas bubbles in the blood circulating in a vessel on which the clamp is placed, conductors are housed in the ends of the two branches surrounding the vessel. Preferably the conductors are embedded in pieces of plastic material coming to adapt in corresponding housings made in these ends, which facilitates the installation and removal without moving the clamp.

Bien entendu une telle pince est livrée et utilisée en conditions stériles et jetée après usage. Of course, such a clamp is delivered and used in sterile conditions and discarded after use.

On va décrire maintenant plus en détail la pince selon l'invention, en se référant au dessin annexé , sur lequel
- la figure I est une vue déployée de la pince selon l'invention
- la figure 2 est une vue de profil de la même pince, et
- les figures 3 et 3a sont deux vues en perspective identiques, la pince étant respectivement en position fermée et ouverte.
We will now describe in more detail the clamp according to the invention, with reference to the accompanying drawing, in which
- Figure I is a deployed view of the clamp according to the invention
FIG. 2 is a side view of the same clamp, and
- Figures 3 and 3a are two identical perspective views, the clamp being respectively in the closed and open position.

Sur ce dessin, la pince selon l'invention se compose d'une bande continue 1, ayant la forme apparaissant à la figure 1, c'est-à-dire comportant une zone centrale C et deux branches
B1 et B2.
In this drawing, the clamp according to the invention consists of a continuous strip 1, having the shape appearing in FIG. 1, that is to say comprising a central zone C and two branches
B1 and B2.

La zone centrale C est arrondie au moulage sur presque 3600, de sorte que les branches B1 et B2 viennent pratiquement se placer côte à côte. La branche B1 présente une échancrure 2 pratiquée vers le bas et la branche B2 présente une échancrure 3 pratiquée vers le haut, ayant pratiquement toutes deux la même profondeur, de sorte que les deux extrémités respectives 4 et 5 peuvent venir se croiser en 6, de manière telle que leurs faces externes 7 et 8 viennent en regard l'une de l'autre, comme il apparaît mieux aux figures 3 et 3a. The central zone C is rounded on molding on almost 3600, so that the branches B1 and B2 come practically to be placed side by side. The branch B1 has a notch 2 made downwards and the branch B2 has a notch 3 made upwards, practically both having the same depth, so that the two respective ends 4 and 5 can come to cross at 6, in such a way that their external faces 7 and 8 come opposite one another, as it appears better in FIGS. 3 and 3a.

Ces faces en regard 7 et 8 sont concaves, et adaptées à la forme et aux dimensions des vaisseaux sur lesquels la pince sera adaptée. These opposite faces 7 and 8 are concave, and adapted to the shape and dimensions of the vessels on which the clamp will be adapted.

L'usage de la pince résulte clairement des figures 3 et 3a. La forme normale de la pince, telle qu'elle vient de moulage, et sans subir de sollicitation, est celle de la figure 3. L'élasticité de la zone centrale C tend à écarter les branches
B1 et B2, et comme les extrémités 4 et 5 de ces branches sont inversées, puisqu'elles se croisent en 6, elles tendent à se refermer suivant les flèches F-F', donc à pincer ltobjet situé entre elles. C'est l'état actif de la pince. Le choix de la matière, de ses dimensions et de la forme arrondie de la zone C sont tels que les forces F-F' sont efficaces sans risquer de meurtrir ou d'endommager le vaisseau sur lequel elles s'exercent.
The use of the clamp clearly results from FIGS. 3 and 3a. The normal shape of the clamp, as it comes from molding, and without being subjected to stress, is that of FIG. 3. The elasticity of the central zone C tends to spread the branches apart
B1 and B2, and as the ends 4 and 5 of these branches are reversed, since they cross at 6, they tend to close according to the arrows F-F ', therefore pinching the object situated between them. This is the active state of the clamp. The choice of material, its dimensions and the rounded shape of the zone C are such that the forces FF ′ are effective without risking bruising or damaging the vessel on which they are exerted.

Si l'on exerce une pression, schématisée par les forces Fl-Fl, sur la partie inférieure 9-9' de la zone arrondie
C, les branches 4 et 5 seront écartées, et l'objet pincé sera libéré. Compte-tenu de la longueur des branches, on peut dire que l'action de pose et de dépose de la pince se fait à distance, ce qui est une grande commodité pour le chirurgien.
If one exerts a pressure, diagrammed by the forces Fl-Fl, on the lower part 9-9 'of the rounded zone
C, branches 4 and 5 will be discarded, and the pinched object will be released. Given the length of the branches, it can be said that the action of placing and removing the clamp is done remotely, which is a great convenience for the surgeon.

Dans le cas du simple pincement d'un vaisseau, la pince est utilisable telle quelle vient d'etre décrite. In the case of simple pinching of a vessel, the clamp can be used as it has just been described.

Une autre application particuliàremenc intéressante est celle dans laquelle elle sert de support aux conducteurs destinés à la détection et au comptage de corpuscules dans la circulation sanguine, par exemple pour détecter la présence de bulles gazeuses ou l'écoute d'autres bruits physiologiques au moyen d'un détecteur à ultra-sons tel que décrit dans le brevet fran is précité. Dans ce cas, des logements sont pratiqués dans les extrémités 4 et 5 des branches Bl et B2, et dans ces logements peuvent venir se placer des bornes 10-10' où se terminent lesdits conducteurs, à travers un canal tel que représenté en il sur la figure 2. Another particularly interesting application is that in which it serves as a support for the conductors intended for the detection and counting of corpuscles in the blood circulation, for example for detecting the presence of gas bubbles or listening to other physiological noises by means of 'an ultrasonic detector as described in the aforementioned French patent. In this case, housings are made in the ends 4 and 5 of the arms Bl and B2, and in these housings can be placed terminals 10-10 'where said conductors end, through a channel as shown in it on Figure 2.

Bien entendu, une telle pince pourra recevoir d'autres applications dans le domaine médical et chirurgical et pourra donc subir les adaptations correspondantes sans que l'on sorte pour autant du cadre de la présente invention  Of course, such a clamp can receive other applications in the medical and surgical field and can therefore undergo the corresponding adaptations without departing from the scope of the present invention.
