Description
La présente invention concerne une pince chirurgicale pour suturer mécaniquement et de façon linéaire par agrafes, des viscères de cavités abdominales et thoraciques par exemple. The present invention relates to a surgical clamp for suturing mechanically and linearly by staples, viscera of abdominal and thoracic cavities for example.
On connais différenles pinces chirurgicales pour la suture mécanique linéaire d'organes des cavités abdominales et thoraciques telles que décrites dans les brevets FR 1 237 035, 1 278 616, 1 448 441, 1 479 134, 1 540 226, DE 618 922, US 3 080 564, les pinces décrites et revendiquées présentent toutes une tête d'agrafage fixée au corps de pince, de ce fait elles ne sont pas interchangeables ni orientables, ce qui limite leur utilisation dans bien des cas, dîautre part elles sont d'un emploi malaisé car elles nécessitent lors de l'intervention une manipulation par les deux mains du praticien. Various surgical clips are known for the linear mechanical suture of organs of the abdominal and thoracic cavities as described in patents FR 1 237 035, 1 278 616, 1 448 441, 1 479 134, 1 540 226, DE 618 922, US 3 080 564, the clamps described and claimed all have a stapling head attached to the clamp body, therefore they are not interchangeable or steerable, which limits their use in many cases, on the other hand they are of a difficult job because they require during the intervention manipulation by both hands of the practitioner.
L'invention a pour but de palier aux inconvénients préce- demment exposes. The object of the invention is to overcome the disadvantages previously described.
L'invention a pour objet une pince chirurgicale pour sutures mécaniques linéaires de viscères de cavités abdominales et thoraciques comportant un corps de pince prolongé par un canon servant de guide à une bague de verrouillage extérieure et intérieurement à un élément coulissant dans lequel est maintenu un poussoir mobile, en l'extrémité du canon une gorge de retenue est aménagée pour recevoir une arete#aména,gée en extrémité du prolongement d'une tête orientable et amovible comportant un support coulissant de chargeur d'agrafes, une enclume et un marteau prolongé par un poussoir coulissant maintenu à l'intérieur d'un élément relié au support, ledit élément est maintenu et coulisse à l'intérieur du prolongement /du canon de la tête, il est en alignement avec l'élément ainsi que les poussoirs entre eux de sorte à ce que par action d'une poignée ~ articulée sur le corps celle-ci provoque en un premier temps le déplacement des éléments pour rapprocher et immobiliser par un dispositif de verrouillage continu le support coulissant et le chargeur d'agrafes vers l'enclume jusqu'à pincement du viscère à suturer placé entre le chargeur et l'enclume puis en un deuxième temps aprés retour en arrière au moyen d'un ressort et abaissement d'une pièce solidaire de ladite poignée le déplacement de s poussoir s par action de iite pNpee pour expulser les agrafes du chargeur par le marteau et provoquer leur fermeture sur l'enclume aprés transpercement dlrviscère, lors du déverrouillage les poussoirs et les éléments coulissants étant repoussés à leur position initiale au moyen d'un ressort maintenu à l'intérieur du prolongement de la tête. The invention relates to a surgical forceps for linear mechanical sutures of viscera of abdominal and thoracic cavities having a clamp body extended by a barrel serving as a guide to an outer locking ring and internally to a sliding element in which is maintained a pusher mobile, at the end of the barrel a retaining groove is arranged to receive a ridge # arranged at the end of the extension of a directional and removable head having a sliding staple loader support, an anvil and a hammer extended by a sliding pusher held inside an element connected to the support, said element is held and slides inside the extension / barrel of the head, it is in alignment with the element and the pushers between them; so that by action of a handle ~ articulated on the body it causes in a first time the movement of the elements for close and immobilize the sliding support and the staple magazine by means of a continuous locking device towards the anvil until the suturing viscera are squeezed between the magazine and the anvil, then in a second step afterwards by a spring and lowering of a piece integral with said handle the movement of s pushers by action pNpee said to expel the staples of the loader by the hammer and cause their closure on the anvil after piercing the rviscere, when unlocking the pushers and the sliding elements being pushed back to their initial position by means of a spring held inside the extension of the head.

Telle que représentée figures 1 2 et 4 > la pince comporte un corps 1 prolongé par un canon 2 sur lequel coulisse une bague de verrouillage 3 celle-ci en sa partie inférieure coté corps 1 est dotée d'une gachette 4 coulissant dans la rainure 5 aménagée dans le corps et ce afin de déverrouiller la tête orientable 6et permettre son orientation, la course de la gachette 4 par action d'un des doigts du praticien étant limitée lorsque celui-ci vient en butée sur le corps 1, de sorte à permettre seulement le déverrouillage de ladite tête sans toutefois permettre son extraction,en extrémité 7 de la bague 3 un ressort de rappel 8 est maintenu afin de pousser la bague 3 lors du relachement de la gachette 4 et ce aprés orientation de la tête 6, le verrouillage de la tête 6 à la position désirée étant obtenu par l'emboftement de dents 9 aménagées sur le pourtour intérieur 10 de la bague 3 dans les rainurés 11 aménagées sur le pourtour extérieur du prolongement 12 de la tête 6. As shown in Figures 1 2 and 4> the clamp comprises a body 1 extended by a barrel 2 on which slides a locking ring 3 thereof in its lower part side body 1 is provided with a trigger 4 sliding in the groove 5 arranged in the body and in order to unlock the orientable head 6 and allow its orientation, the stroke of the trigger 4 by action of one of the practitioner's fingers being limited when the latter abuts on the body 1, so as to allow only the unlocking of said head without allowing its extraction, end 7 of the ring 3 a return spring 8 is maintained in order to push the ring 3 when releasing the trigger 4 and after orientation of the head 6, the locking of the head 6 at the desired position being obtained by the embotement of teeth 9 arranged on the inner periphery 10 of the ring 3 in the grooves 11 arranged on the outer periphery of the extension 12 d e the head 6.
Afin de permettre la mise en place d'une tête 6 sur le canon 2 la bague coulissante 3 est repoussée manuellement vers le corps 1 de sorte à dégager la gorge de retenue 13 de la tête 6 aménagée sur le canon 2 pour qu'aprés coulissement du prolongement 12 sur le canon 2 l'ar8te 14 en bout dudit prolongement s'emboue dans la gorge de retenue 13 et ce par simple effet de ressort dû à la matière constituant le prolongement 12 et engendré par des rainures 15 disposées sur le pourtour dudit prolongement 12. In order to allow the installation of a head 6 on the barrel 2 the sliding ring 3 is manually pushed towards the body 1 so as to clear the retaining groove 13 of the head 6 arranged on the barrel 2 so that after sliding of the extension 12 on the barrel 2 the edge 14 at the end of said extension engulfs in the retaining groove 13 and this by simple spring effect due to the material constituting the extension 12 and generated by grooves 15 disposed on the periphery of said extension 12.
A l'intérieur du canon 2 coulisse un élément 16,ce dernier a pour foncion de provoquer le déplacement du support 17 de chargeur d'agrafes 19 au moyen de l'élément 18 coulissant dans le prolongement de tête 12 et ce de manière à rapprocher le chargeur d'agrafes 19 vers l'enclume 20, le déplacement de l'élément 16 est obtenu au moyen de la poignée 21 articulée sur le corps 1 dotéed'un ressort de rappel 22, lorsque ladite poignée est actionnée celle-ci en son extrémité 23 prend appui sur un élément coulissant 24 maintenu sur le corps 1 et sur un côté duquel des dents 25 sont aménagées afin de constituer avec le cliquet articulé 26 doté d'un ressort 26A un verrouillage continu durant le déplacement progressif de l'élément 16 relié à l'élément coulissant 24 par l'âme 27, ledit verrouillage pouvant être libéré par action d'un bouton poussoir 23. En fin de rapprochement du support 17 de chargeur d'agrafes 19 sur l'enclume 20, le viscère à suturer placé entre le chargeur 19 et l'enclume 20 subit une pression obtenue au moyen du ressort de compression 29 maintenu dans l'ëlé- ment coulissant 24, par relachement de la poignée 21 rappelée par le ressort 22, alors que le support 17 de chargeur est maintenu en position de pincement et seulement à ce moment-là, la pièce 30 solidaire et coulissant dans la poignée 21 au moyen du bouton 31 est placée en face du poussoir 32 du corps de pince 1 coulissant dans l'élément 16 de manière à ce que par action de la poignée 21 la pièce 30 prenne appui sur l'extrémité 33 dudit poussoir 32 et provoque son déplace ment ainsi que celui du poussoir 34 solidaire et coulissant dans l'éIe:rnent. 18 de la tete 6 pour engendrer l'expulsion des agrafes con- tenues dans le chargeur 19 et leur fermeture sur ltenclume 20 aprés transpercement du viscère, par le marteau- 44 fixé en extrémité 45 du poussoir 34, la pièce 30 lors de l'action de la poignée 21 pendant le déplacement du support 17 de.chargeur d'agrafes 19 en position haute permet le libre passage de l'extrémité du poussoir 32. Inside the barrel 2 slides an element 16, the latter function of causing the displacement of the staple magazine support 19 by means of the sliding element 18 in the extension of the head 12 and so as to bring closer the staple magazine 19 towards the anvil 20, the displacement of the element 16 is obtained by means of the handle 21 hinged to the body 1 provided with a return spring 22, when said handle is actuated thereof in its end 23 is supported on a sliding member 24 held on the body 1 and on one side of which teeth 25 are arranged to constitute with the hinged pawl 26 with a spring 26A a continuous lock during the progressive movement of the element 16 connected to the sliding element 24 by the core 27, said locking being released by the action of a pushbutton 23. At the end of bringing the support 17 of the staple magazine 19 closer to the anvil 20, the suturing viscera square between the magazine 19 and the anvil 20 is subjected to a pressure obtained by means of the compression spring 29 held in the sliding element 24, by releasing the handle 21 which is biased by the spring 22, whereas the magazine support 17 is maintained in the pinching position and only at this moment, the piece 30 integral and sliding in the handle 21 by means of the button 31 is placed in front of the pusher 32 of the gripper body 1 sliding in the element 16 so that that by action of the handle 21 the piece 30 bears on the end 33 of said pusher 32 and causes its displacement and that of the pusher 34 integral and sliding in the éIe: rnent. 18 of the head 6 to cause the expulsion of the staples contained in the loader 19 and their closure on the hoop 20 after piercing of the viscera, by the hammer-44 fixed at the end 45 of the pusher 34, the piece 30 when the action of the handle 21 during the displacement of the staple loader support 19 in the high position allows the free passage of the end of the pusher 32.
De sorte à permettre l'alDaisselnent de dela pièce 30, lors de l'opération de pincement par le support coulissant 17 du chargeur d'agrafes 19, les poussoirs 32 et 34 sont en même temps déplacés et ce grâce à une goupille 35 en appui sur l'cxtrémité 36 d'une lumière 37 aménagée sur l'él~rnent 16 et la goupille 38 solidaire du poussoir 34 en appui sur les extrémités 39 des lumières se faisant face 40, la goupille 38 servant notamment d'appui au ressort 41 de rappel contenu entre l'élément 18 et le prolongement 12 permettant l'ouverture et dégagement du support 17 du chargeur d'agrafes 19 lorsque le cliquet 26 est désolidarisé des dents 25. In order to allow the addition of the piece 30, during the pinching operation by the sliding support 17 of the staple magazine 19, the pushers 32 and 34 are at the same time displaced by means of a pin 35 in support. on the end 36 of a light 37 arranged on the el ~ rnent 16 and the pin 38 secured to the pusher 34 resting on the ends 39 of the lights facing each other 40, the pin 38 serving in particular to support the spring 41 of return contained between the element 18 and the extension 12 allowing the opening and release of the support 17 of the staple magazine 19 when the pawl 26 is disengaged from the teeth 25.
Sans sortir du cadre de l'invention et telle que représentée figure 3, l'orientation de la tête et son maintien peuvent être réalisés au moyen d'un ressort à friction 42 logé dans un évidement 43 prévu à cet effet à l'intérieur de la bague 3,de ce fait les dents 9 et rainures il ainsi que la ga#chette 4 sont supprimées. Without departing from the scope of the invention and as shown in FIG. 3, the orientation of the head and its retention can be achieved by means of a friction spring 42 housed in a recess 43 provided for this purpose inside the the ring 3, thus the teeth 9 and grooves 11 and the bracket 4 are removed.
