Abstract

The invention relates to surgical instruments. The instrument which is the subject of the invention is of the type including a cutting working member in the form of a small spoon 3 and a handle provided with a channel for draining the thrombus, and is characterised in that the cutting part 8 of the spoon 3, intended to enter into direct contact with the organ to be operated upon, has a rectangular shape. The invention may be used in particular during operations on the heart intended to separate thrombi from the walls of the atria and their reliable removal from the cardiac cavity.

Description

La présente invention concerne les instruments chirurgicaux et a notamment pour objet un instrument destiné à la thrombectomie. The present invention relates to surgical instruments and in particular relates to an instrument intended for thrombectomy.

L'invention peut servir plus précisément en chirurgie cardiaque, lors des opérations sur le coeur visant la séparation des thrombi des parois des oreillettes et leur élimination fiable de la cavité cardiaque. The invention can be used more specifically in cardiac surgery, during operations on the heart aimed at the separation of thrombi from the walls of the atria and their reliable elimination from the cardiac cavity.

On connaît un instrument destiné à éliminer les fluides et les tissus au cours d'une opération ou d'examens, et qui comporte un manche, une tige traversant le manche et un organe de travail tranchant sous la forme d'une cuiller curviligne, notamment de forme ovale ou circulaire (cf. le Catalogue "Instruments, appareils et matériels médicaux", Compléments, NO 06-71, 06-72, 06-73,p. 252). An instrument is known for removing fluids and tissues during an operation or examinations, and which comprises a handle, a rod passing through the handle and a cutting working member in the form of a curvilinear spoon, in particular oval or circular in shape (see the Catalog "Medical instruments, devices and materials", Complements, NO 06-71, 06-72, 06-73, p. 252).

Un inconvénient dudit instrument tient à ce qu'il est impossible de l'utiliser dans les opérations sur le coeur, étant donné que, lors de la thrombectomie sur les parois de l'oreillette, la cuiller ovale ou circulaire ne traite, à chaque passe, qu'une aire très limitée de la paroi de l'oreillette, et qu'une augmentation,même faible, de l'effort appliqué à l'instrument risque de traumatiser la paroi de l'oreillette et de fragmenter le-thrombus en petites particules. A disadvantage of said instrument is that it is impossible to use it in operations on the heart, since, during thrombectomy on the walls of the atrium, the oval or circular spoon does not treat, with each pass , that a very limited area of the wall of the atrium, and that even a slight increase in the force applied to the instrument risks traumatizing the wall of the atrium and fragmenting the thrombus into small particles.

En outre, les thrombi ablatés, lors de leur extraction de la cavité cardiaque, ont tendance à quitter la cuiller, ce qui met le malade en danger. In addition, the ablated thrombi, when they are extracted from the heart cavity, tend to leave the spoon, which puts the patient in danger.

On connaît d'autre part un instrument destiné à la thrombectomie, qui comporte une partie de travail tranchante sous la forme d'une cuiller ovale qui est réunie à un manche dans lequel est pratiqué un canal destiné à l'évacuation du thrombus et qui est réuni à une pompe à vide (cf. certificat d'auteur URSS N0143 510, 1961, Classification internationale A61B 17/32). On the other hand, there is known an instrument intended for thrombectomy, which comprises a sharp working part in the form of an oval spoon which is joined to a handle in which is formed a channel intended for the evacuation of the thrombus and which is combined with a vacuum pump (cf. USSR author's certificate N0143 510, 1961, International classification A61B 17/32).

Un tel instrument, au cours de la séparation du thrombus de la paroi de l'oreillette, ne traite, à chaque passe, qu'une aire limitée, et si l'on accroît l'effort, on risque de traumatiser la paroi de l'oreillette. Such an instrument, during the separation of the thrombus from the wall of the atrium, only treats, on each pass, a limited area, and if the effort is increased, there is a risk of traumatizing the wall of the headset.

On s'est donc proposé de créer un instrument pour thrombectomie qui permettrait d accroître la zone de la surface de la paroi de l'oreillette pouvant être traitée en une passe, et ce, sans traumatisation des parois de l'oreillette, ni chute des thrombi ablatés hors de l'instrument au moment de leur extraction de la cavité cardiaque. It has therefore been proposed to create a thrombectomy instrument which would make it possible to increase the area of the surface of the wall of the atrium which can be treated in one pass, and this, without trauma to the walls of the atrium, or fall of the thrombi ablated out of the instrument when extracted from the heart cavity.

Ce but est atteint du fait que l'instrument pour thrombectomie, du type comportant un organe de travail tranchant sous la forme d'une petite cuiller et un manche pourvu d'un canal pour l'évacuation du thrombus, est caractérisé,suivant l'invention, en ce que la partie tranchante de la cuiller qui entre directement en contact avec la paroi de l'organe à opérer a une forme rectangulaire. This object is achieved by the fact that the thrombectomy instrument, of the type comprising a cutting working member in the form of a small spoon and a handle provided with a channel for the evacuation of the thrombus, is characterized, according to the invention, in that the cutting part of the spoon which comes into direct contact with the wall of the member to be operated has a rectangular shape.

Il est avantageux que cette cuiller ait une cavité fermée formée par son fond et une lame fixée dans la cavité proprement dite de la cuiller, et communiquant avec le canal pour l'évacuation du thrombus, et que dans la lame soit pratiqué un orifice pour le passage du thrombus de la cavité proprement dite de la cuiller dans ladite cavité fermée. It is advantageous that this spoon has a closed cavity formed by its bottom and a blade fixed in the proper cavity of the spoon, and communicating with the channel for the evacuation of the thrombus, and that in the blade is made an orifice for the passage of the thrombus from the proper cavity of the spoon into said closed cavity.

L'invention sera mieux comprise et d'autres buts, détails et avantages de celle-ci apparaîtront mieux à la lumière de la description explicative qui va suivre de différents modes de réalisation donnés uniquement à titre d'exemple non limitatif avec références au dessin unique annexé dans lequel
- la figure 1 représente l'instrument pour thrombectomie conforme à l'invention (vue d'ensemble avec coupe partielle;
- la figure 2 représente une vue de la cuillère de l'instrument.
The invention will be better understood and other objects, details and advantages thereof will appear better in the light of the explanatory description which will follow of various embodiments given solely by way of nonlimiting example with references to the single drawing. annexed in which
- Figure 1 shows the thrombectomy instrument according to the invention (overview with partial section;
- Figure 2 shows a view of the spoon of the instrument.

L'instrument pour thrombectomie comporte un manche 1 (figure 1) à l'intérieur duquel passe une tige 2 et qui est assemblé à l'organe de travail tranchant, sous forme d'une cuiller 3, de l'instrument. The thrombectomy instrument comprises a handle 1 (FIG. 1) inside which passes a rod 2 and which is assembled to the cutting working member, in the form of a spoon 3, of the instrument.

La tige est exécutée sous la forme d'un tube dont l'extrémité 4 sort du manche 1 et peut se raccorder à une pompe à vide (non représentée sur les figures). The rod is executed in the form of a tube whose end 4 comes out of the handle 1 and can be connected to a vacuum pump (not shown in the figures).

Dans le manche 1 et la tige 2 sont pratiqués des orifices latéraux coaxiaux 5 et 6 qui mettent en communication la cavité 7 de la tige 2 avec l'atmosphère. In the handle 1 and the rod 2 are formed coaxial lateral orifices 5 and 6 which put the cavity 7 of the rod 2 in communication with the atmosphere.

La partie de travail tranchante 8 (figure 2) de la cuiller 3,destinée à entrer en contact direct avec la paroi de l'organe à opérer, a une forme rectangulaire. Ceci permet d'augmenter la surface de la paroi de l'oreillette, avec laquelle la cuiller 3 viendra en contact lors du traitement en une seule passe dudit organe. The sharp working part 8 (FIG. 2) of the spoon 3, intended to come into direct contact with the wall of the member to be operated, has a rectangular shape. This makes it possible to increase the surface of the wall of the atrium, with which the spoon 3 will come into contact during the treatment in a single pass of said member.

Dans la cavité de la cuiller 3 est fixée une lame 9 (figure 1) qui forme avec le fond 10 de la cuiller une cavité fermée 11 communiquant avec la cavité 7 de la tige 2 servant da canal d'évacuation des thrombi. In the cavity of the spoon 3 is fixed a blade 9 (Figure 1) which forms with the bottom 10 of the spoon a closed cavity 11 communicating with the cavity 7 of the rod 2 serving da thrombi evacuation channel.

La cavité fermée 11 communique avec la cavité proprement dite de la cuiller 3 par une fenêtre 12 (figure 2) pratiquée dans la lame 9 et permettant le passage et la sortie du thrombus ablaté de la cavité proprement dite de la cuiller dans la cavité 11. The closed cavity 11 communicates with the proper cavity of the spoon 3 through a window 12 (FIG. 2) made in the blade 9 and allowing the passage and the exit of the ablated thrombus from the proper cavity of the spoon in the cavity 11.

On utilise l'instrument de thrombectomie, lors d'une opération sur le coeur, de la manière suivante.  The thrombectomy instrument is used, during an operation on the heart, in the following manner.

On raccorde l'instrument à une pompe à vide. A travers l'incision pratiquée sur le coeur, on introduit l'instrument dans l'oreillette et, en le déplaçant doucement sur la paroi de l'oreillette, on enlève avec l'arête tranchante 13 (figure 2) les thrombi fixés à la paroi de l'oreillette. Ensuite le chirurgien obture les orifices coaxiaux 5 et 6 en appliquant son doigt sur le manche 1 et, en mettant en communication la pompe à vide, par l'intermédiaire de la cavité 7 de la tige 2, avec la cavité fermée 11, il fixe les thrombi ablatés sur le fond 10 de la cuiller, ou ils pénètrent par la fenêtre 12 de la lame 9. The instrument is connected to a vacuum pump. Through the incision made on the heart, the instrument is inserted into the atrium and, by gently moving it over the wall of the atrium, the thrombi attached to the head are removed with the cutting edge 13 (Figure 2). wall of the atrium. Then the surgeon plugs the coaxial orifices 5 and 6 by applying his finger to the handle 1 and, by putting the vacuum pump in communication, through the cavity 7 of the rod 2, with the closed cavity 11, he fixes the ablated thrombi on the bottom 10 of the spoon, or they penetrate through the window 12 of the blade 9.

Ensuite on extrait du coeur la cuiller 3 contenant les thrombi dans la cavité 11. On enlève les thrombi de la cuiller 3 en ouvrant les orifices coaxiaux 5 et 6 dans le manche 1. Then the spoon 3 containing the thrombi is extracted from the heart in the cavity 11. The thrombi are removed from the spoon 3 by opening the coaxial orifices 5 and 6 in the handle 1.

L'instrument de thrombectomie revendiqué permet de traiter la paroi de l'oreillette sur une surface beaucoup plus grande et en un temps beaucoup plus court que ne le permettent les instruments connus. Il permet d'autre part d'éviter les traumatismes des parois de l'oreillette et assure de façon fiable la rétention de thrombi ablatés de diverses dimensions en prévenant leur chute dans la cavité cardiaque. Cela prévient les complications emboliques, c'est-à-dire l'oblitération des vaisseaux vitaux du malade.  The claimed thrombectomy instrument makes it possible to treat the wall of the atrium over a much larger surface and in a much shorter time than the known instruments allow. It also helps to avoid trauma to the walls of the atrium and reliably ensures the retention of ablated thrombi of various dimensions by preventing their fall into the heart cavity. This prevents embolic complications, that is, the obliteration of the patient's vital vessels.
