La fig. Fig. 7 est une vue en coupe prise sensiblement selon les lignes VII-VII de la fig. 7 is a sectional view taken substantially along the lines VII-VII of FIG. 6. 6.

Les fig. FIGS. 1 et 2, illustrent un dispositif 1 conforme à l'invention, utilisé en coeliochirurgie et destiné à assurer le blocage d'au moins un fil, au sens général, pour réaliser, par exemple un surjet, une suture ou une Ligature. 1 and 2 illustrate a device 1 according to the invention used in laparoscopic surgery and intended to ensure the locking of at least one wire in a general sense to realize, for example a continuous suture, a suture or ligature. Le dispositif de blocage 1 selon L'invention comporte une pièce mâle 2, destinée à être emboîtée au moins partiellement à l'intérieur d'une pièce femelle 3. Les pièces 2 et 3 sont adaptées pour ménager entre elles, lors de leur emboîtement, au moins une zone 4 assurant le coincement d'au moins un et, dans l'exemple illustré, de deux parties terminales 51 d'un ou de deux fils 5. The locking device 1 according to the invention comprises a male part 2 intended to be nested at least partially within a female part 3. Parts 2 and 3 are adapted to provide between them at their engagement, at least one region 4 providing the clamping of at least one and, in the example illustrated, two end portions 51 of one or two son 5.

Dans l'exemple illustré aux fig. In the example shown in Fig. 1 et 2, la pièce mâle 2 est réalisée sous la forme d'un tronc de cône, par exemple de base circulaire, tandis que la pièce femelle 3 comporte un alésage 6 de forme complémentaire à l'enveloppe de la pièce mâle 2. Selon cet exempLe, les fils 5 s'étendent de part et d'autre du diamètre de la pièce 2, de sorte que Les fils 5 sont coincés par deux zones 4 qui sont délimitées par des surfaces à profil incliné complémentaires, à savoir la surface de révolution extérieure 7 de la pièce mâle 2 et la surface de l'alésage 6. 1 and 2, the male part 2 is constructed as a truncated cone, for example, circular base, while the female piece 3 has a bore 6 of complementary shape to the envelope of the male part 2. According this example, the son 5 extend on either side of the diameter of the part 2, so that the son 5 are pinched by two zones 4, which are delimited by complementary inclined profile surfaces, namely the surface of outer revolution 7 of the male part 2 and the surface of the bore 6.

Bien entendu, les pièces mâle 2 et femelle 3 peuvent être réalisées sous d'autres formes que celles représentées aux fig. Of course, the male and female parts 2 3 can be made in shapes other than those shown in Fig. 1 et 2. A titre d'exemple, la fig. 1 and 2. For example, FIG. 3 illustre les pièces 2 et 3 présentant des formes trapézoidales complémentaires, dont les faces planes principales 8 et 9, respectivement des pièces 2 et 3, délimitent deux zones de coincement 4.

De préférence mais non exclusivement, les deux faces planes 8 et 9 peuvent présenter une inclinaison complémentaire pour faciliter le coincement des fils 5. 3 illustrates the parts 2 and 3 having complementary trapezoidal shapes, the principal planar faces 8 and 9 respectively of the parts 2 and 3 delimit two gripping portions 4. For example, the main faces 8 of the male part 2 are parallel therebetween, while the faces 9 of the female part 3 are parallel, so that the play between the surfaces 8, 9 facing each other, ensures the wedging of the son 5. preferably but not exclusively, both sides planes 8 and 9 may have a complementary inclination to facilitate wedging of the son 5.

Selon une caractéristique avantageuse de L'invention, les pièces mâle 2 et femelle 3 sont équipées de moyens assurant According to an advantageous characteristic of the invention, the male and female parts 2 3 are provided with means ensuring
Leur immobilisation relative lorsque ces pièces sont emboîtées L'une dans L'autre. Their relative immobilization when these parts are fitted in One Another. Ces moyens d'immobilisation sont constitués, par exempLe, par des éléments de structures complémentaires portés par les pièces mâle et femelle, tels que, par exemple, des dégagements, des Lumières ou des rainures 12 réalisés, au moins These immobilization means consist, for example, by complementary structures of elements carried by the male and female parts, such as, for example, clearances, lights or grooves 12 made at least
Localement, sur la surface périphérique de la pièce 2 et destinés à coopérer avec des crans, des ergots ou des saillies 13 ménagés à l'intérieur de la pièce 13. Locally, on the peripheral surface of the workpiece 2 and intended to cooperate with notches, lugs or projections 13, formed inside of the part 13.

Selon une autre caractéristique avantageuse de According to another advantageous feature of
L'invention, L'une des pièces, à savoir la pièce mâle 2 dans The invention One of the parts, namely the male part 2 in
L'exemple illustré, comporte au moins une échancrure 14 facilitant la préhension du fil, en vue de son coincement dans la zone 4. The illustrated example includes at least one notch 14 to facilitate the gripping of the yarn, for its clamping in the area 4.

L'échancrure 14 est ménagée selon le diamètre de la pièce mâle 2, selon une direction sensiblement perpendiculaire au sens d'emboîtement des pièces, représentée par la flèche f. The notch 14 is formed depending on the diameter of the male part 2, in a direction substantially perpendicular to the direction of interlocking of the parts, shown by the arrow f. La pièce mâle 2 maintient ainsi les fils 5 lors de l'introduction de la pièce mâle 2 à l'intérieur de la pièce femelle 3. The male part 2 thus keeps the son 5 upon insertion of the male part 2 inside of the female part 3.

La méthode ou le procédé pour bloquer un fil en coeliochirurgie par le dispositif selon L'invention découle directement de la description qui précède. The method or process for blocking a thread coeliochirurgie by the device according to the invention follows directly from the foregoing description. Tel que cela apparaît plus précisément à la fig. As shown more clearly in FIG. 4, la mise en place de ce dispositif de blocage s'effectue par l'intermédiaire d'un instrument 16 de conception classique, comportant un piston 18 commandé en coulissement dans un fourreau 19 par l'intermédiaire d'une tige 20. 4, the introduction of this locking device is effected by means of an instrument 16 of conventional design having a piston 18 slidably controlled in a sleeve 19 via a rod 20.

Il est rappelé que le fourreau présente, généralement, une section de L'ordre de 10 mm et une longueur de l'ordre de 400 mm. It is recalled that the sheath has, generally, a section of the order of 10 mm and a length of about 400 mm. L'instrument délimite, à son extrémité destinée à être insérée à l'intérieur de l'organisme d'une personne, un puits 22 de chargement et d'éjection pour au moins un dispositif de. The instrument defines, at its end intended to be inserted inside the body of a person, a well 22 for loading and ejection to at least one device.

blocage 1. locking one.

A titre d'exemple, le piston 18 maintient, en coopération avec un organe élastique 25 porté par le fourreau 19, les pièces mâle 2 et femelle 3 partiellement emboîtées L'une dans l'autre. For example, the piston 18 holds, in cooperation with an elastic member 25 carried by the sleeve 19, the male and female parts 2 3 partially nested one inside the other.

Après l'introduction de l'extrémité inférieure de l'instrument 16, à l'intérieur de l'organisme, L'instrument est déplacé pour permettre d'engager le ou les fils à bloquer, à l'intérieur de. After the introduction of the lower end of the instrument 16 within the body, the instrument is moved to allow to engage the son or to block, inside.

L'échancrure 14. The notch 14.

Le piston 18 est alors déplacé en coulissement pour assurer l'emboîtement des pièces mâle 2 et femelle 3, de manière à coincer le ou les fils dans les zones 4. Le piston 18 est déplacé de manière que les crans 13 coopèrent avec les rainures 12, en vue d'obtenir une immobilisation relative des deux pièces. The piston 18 is then moved by sliding to ensure the interlocking of the male and female parts 2 3, so as to sandwich the one or more son in the zones 4. The piston 18 is moved so that the notches 13 cooperate with the grooves 12 in order to obtain a relative immobilization of the two parts. Le piston 18 est alors repoussé, de sorte que le dispositif de blocage 1, sollicité élastiquement par L'élément 25, est désolidarisé de l'instrument pour être laissé en place à l'intérieur de l'organisme. The piston 18 is then pushed, so that the locking device 1, the resiliently biased element 25, is separated from the instrument to be left in place within the body.

Le coincement du fil par les zones 4, combiné aux moyens 12, 13 permettant d'immobiliser ensemble les deux pièces 2 et 3, assure l'obtention d'un blocage efficace et durable du ou des fils 5. Un tel dispositif offre l'avantage de permettre la réalisation aisée de noeuds par le coincement des deux parties terminales d'un ou de deux fils. The jamming of the wire zones 4, combined with means 12, 13 for immobilizing together the two parts 2 and 3, ensures obtaining an effective and sustainable blocking or son 5. Such a device offers the advantage of allowing easy realization of nodes by the wedging of the two end portions of one or two son. Le coincement du ou des fils est grandement facilité par ta mise en oeuvre de l'échancrure 14 qui permet de positionner et de guider le ou les fils pendant toute l'opération de blocage. Jamming or the son is greatly facilitated by your implementation of the notch 14 for positioning and guiding the or son during the whole locking operation.

Bien entendu, le dispositif 1 est réalisé en un matériau apte à être supporté par l'organisme d'une personne et peut présenter une longueur pouvant aller jusqu'à 10 mm. Of course, the device 1 is made of a material adapted to be supported by a person's body and may have a length up to 10 mm. De plus, il peut être prévu de réaliser un instrument jetable après la mise en place d'un unique dispositif ou capable de recevoir une batterie de dispositifs de blocage conformes à l'invention, amenés successivement au niveau du puits 22. In addition, it may be provided to provide a disposable instrument after the introduction of a single device or capable of receiving a locking device battery according to the invention, fed successively at the well 22.

La fig. Fig. 5 illustre, à titre d'exemple, une autre variante de réalisation d'un instrument 16 susceptible d'être utilisé en coeliochirurgie pour assurer la mise en place d'un dispositif de blocage 1 conforme à L'invention. 5 illustrates, by way of example, a further alternative embodiment of an instrument 16 capable of being used in laparoscopic surgery to ensure the establishment of a locking device 1 according to the invention. Selon cette variante, les pièces mâle 2 et femelle 3 sont maintenues ensemble lors de leur introduction à l'intérieur de l'organisme, par l'intermédiaire du piston 18 comportant un épaulement 23 de centrage de la pièce femelle 3 et à L'aide d'un lien 26 fixé à La pièce mâle 2 et sur le fourreau extérieur 19. Le déplacement relatif du fourreau 19 par rapport au piston 18 permet d'assurer l'engagement de la pièce mâle 2 à l'intérieur de la pièce femelle 3. La rupture du lien 26 après L'emboîtement complet des deux pièces permet de laisser en place le dispositif de blocage selon l'invention. According to this variant, the male and female parts 2 3 are held together when they are introduced inside the body, via the piston 18 having a shoulder 23 for centering the female part 3 and using a link 26 attached to the male part 2 and the outer sheath 19. the relative displacement of the sleeve 19 relative to the piston 18 ensures the engagement of the male part 2 inside of the female part 3 . breaking the link 26 after the complete fitting of the two parts allows to leave in place the locking device according to the invention.

Les fig. FIGS. 6 et 7 illustrent une autre variante de réalisation du dispositif de blocage 1 selon l'invention. 6 and 7 illustrate another alternative embodiment of the locking device 1 according to the invention. Selon cette variante, les pièces mâle 2 et femelle 3 sont articulées selon une ligne commune de pivotement 27. La pièce mâle 2 se présente sous la forme d'une coque dont le fond 30 est bordé par deux flancs latéraux 31 présentant chacun une forme trapézoidale. According to this variant, the male and female parts 2 3 are articulated on a common pivot line 27. The male part 2 is in the form of a shell whose bottom 30 is bounded by two side faces 31 each having a trapezoidal shape .

Tel que cela apparaît plus précisément à la fig 7, les flancs 31 sont évasés pour délimiter, avec les flancs 32 de la pièce mâle 2, deux zones de coincement 4 pour un fil 5. Avantageusement, il est prévu de réaliser, sur le fond 30 de la pièce femelle 3, une languette 35 destinée à coopérer avec une rainure 36 pratiquée dans la pièce mâle 2. Une telle configuration forme une chicane constituant une zone supplémentaire de coincement pour le fil, permettant d'assurer un blocage fixe d'un fil. As shown more clearly in FIG 7, the sidewalls 31 are flared to define, with the sidewalls 32 of the male part 2, two clamping zones 4 for a wire 5. Advantageously, it is intended to perform in the background 30 of the female part 3, a tongue 35 adapted to cooperate with a groove 36 formed in the male part 2. such a configuration forms a baffle constituting an additional clamping area for the wire, ensuring a fixed blocking a thread.

D'une façon avantageuse, la pièce mâle 2 est aménagée pour comporter du moins une échancrure 14 ménagée à partir de la ligne de pivotement 27, de manière à assurer, d'une part, l'engagement du fil et, d'autre part, à éviter tout glissement du fil lors du pivotement relatif des deux pièces. Advantageously, the male part 2 is arranged to include at least one indentation 14 formed from the pivot line 27, so as to ensure on the one hand, the engagement of the wire and, on the other hand , to prevent slippage of the wire during the relative pivoting of the two parts. Le blocage définitif de ces deux pièces peut être assuré par l'intermédiaire d'un ergot 13 ménagé sur la pièce mâle 2 et destiné à coopérer avec un logement 12 pratiqué sur le retour 37 de la pièce femelle 3. The final locking of these two parts can be ensured by means of a lug 13 provided on the male part 2 and designed to cooperate with a housing 12 carried on the back 37 of the female part 3.

Bien entendu, la mise en place d'un tel dispositif est effectuée à l'ai de d'un instrument pourvu, à son extrémité, d'un système à pinces, pour assurer le pivotement et l'emboîtement des pièces 2 et 3. Of course, the implementation of such a device is performed to have a tool provided at its end with a gripper system for pivoting and snapping the parts 2 and 3.

L'invention n'est pas limitée aux exemples décrits et représentés, car diverses modifications peuvent y être apportées sans sortir de son cadre. The invention is not limited to the examples described and shown, as various modifications may be made without departing from its scope.
