Abstract
Description
La présente invention a trait à une pince ancillaire pour faciliter la pose de plaques d'ostéosynthèse maxillo-faciale. The present invention relates to ancillary forceps to facilitate the placement of maxillofacial osteosynthesis plates.
On utilise, en chirurgie maxillo-faciale, des plaques d'ostéosynthèse, destinées à rester implantées provisoirement ou en permanence et se présentant généralement sous forme de lames rectilignes ou coudées, avec ou sans embranchements, et munies de trous ou oeillets agencés pour recevoir des têtes de vis, et présentant, de préférence, à cet effet, des sièges ou portées sphériques. Ces plaques comportent des oeillets qui sont généralement séparés par des portions de lame dites ponts. In maxillofacial surgery, osteosynthesis plates are used, intended to remain implanted temporarily or permanently and generally in the form of straight or angled blades, with or without branches, and provided with holes or eyelets arranged to receive screw heads, and preferably having, for this purpose, spherical seats or surfaces. These plates have eyelets which are generally separated by blade portions called bridges.
Ces lames doivent être résistantes, malléables pour pouvoir être déformées à la convenance du chirurgien, et bien supportées par le patient. On réalise donc généralement les lames en titane de pureté élevée. These blades must be resistant, malleable in order to be deformed at the convenience of the surgeon, and well supported by the patient. The blades are therefore generally made of high purity titanium.
Quant aux vis, pour des raisons de résistance à la rupture, elles sont en alliage de titane.As for the screws, for reasons of breaking strength, they are made of titanium alloy.
En cas de fractures maxillaires ou faciales, le chirurgien pratique une voie d'abord convenable et libère par ruginage une surface adaptée de la corticale osseuse de part et d'autre de la ligne de fracture. Après avoir procédé à une réduction rigoureuse de la fracture, il maintient la plaque appliquée contre la fracture et procède au forage des passages de vis en se servant des oeillets de la plaque comme guides. I1 procède ensuite au vissage des vis de titane pour immobiliser définitivement la plaque. In the event of maxillary or facial fractures, the surgeon uses a suitable approach and frees up a suitable surface of the cortical bone on either side of the fracture line. After having made a rigorous reduction of the fracture, he keeps the plate applied against the fracture and proceeds to drill the screw passages using the eyelets of the plate as guides. I1 then proceeds to screw the titanium screws to immobilize the plate definitively.
Généralement, après avoir choisi une plaque d'ostéosynthèse idoine le chirurgien la modèle ou la déforme pour lui donner la conformation adaptée aux surfaces osseuses en présence. Il doit ensuite procéder au forage des avant-trous dans lesquels seront vissées les vis de maintien de la plaque, en général au moins deux vis pour chaque côté de la fracture. Pour cela, il maintient manuellement la plaque dans la position qui doit être la sienne et procède au forage des avant-trous à travers les oeillets de la plaque. Cette opération est particulièrement délicate car le chirurgien doit non seulement éviter de faire bouger la plaque mais encore éviter que le foret n'attaque le bord interne de l'oeillet et ne détache de petites particules de titane pouvant entraîner une métallose. Generally, after having chosen an appropriate osteosynthesis plate, the surgeon models it or deforms it to give it the conformation adapted to the bone surfaces present. He must then proceed to drill the pilot holes into which the screws to hold the plate will be screwed, generally at least two screws for each side of the fracture. For this, he manually maintains the plate in the position which must be his and proceeds to drill the pilot holes through the eyelets of the plate. This operation is particularly delicate because the surgeon must not only avoid moving the plate but also prevent the drill from attacking the internal edge of the eyelet and detaching small particles of titanium which can cause metallosis.
La présente invention se propose de remédier à ces inconvénients et de fournir une pince ancillaire qui permette au chirurgien de procéder à l'ensemble de ces opérations en minimisant les risques énumérés cidessus. The present invention proposes to remedy these drawbacks and to provide ancillary forceps which allow the surgeon to carry out all of these operations while minimizing the risks listed above.
L'invention a pour objet une pince ancillaire pour plaques d'ostéosynthèse maxillo-faciale, possédant deux branches se terminant par des mors respectifs, articulées autour d'un axe commun et possédant des moyens de blocage usuels du type à crans, caractérisée en ce que les deux mors présentent des moyens de réception de plaque susceptibles de recevoir une plaque au niveau d'un de ses oeillets et de serrer la plaque pour la maintenir dans une position fixe par rapport à la pince, lesdits mors étant agencés pour présenter un passage circulaire coaxial à l'axe géométrique de l'oeillet maintenu dans la pince pour laisser passer et guider un foret, et de préférence, suivi d'un élargissement en forme de cuvette permettant de recevoir la tête de la vis, de sorte que celle-ci peut être vissée à travers ladite pince jusqu'à une position très proche de la position finale. The subject of the invention is an ancillary clamp for maxillofacial osteosynthesis plates, having two branches ending in respective jaws, articulated around a common axis and having usual locking means of the notch type, characterized in that that the two jaws have plate receiving means capable of receiving a plate at one of its eyelets and of tightening the plate to maintain it in a fixed position relative to the clamp, said jaws being arranged to present a passage circular coaxial with the geometrical axis of the eyelet held in the pliers to allow a drill to pass and guide, and preferably, followed by a widening in the form of a cup making it possible to receive the head of the screw, so that it it can be screwed through said clamp to a position very close to the final position.
De plus on peut assurer ainsi un guidage de foret en évitant un contact substantiel avec le bord de l'oeillet de la plaque. In addition, a drill guide can thus be ensured, avoiding substantial contact with the edge of the plate eyelet.
De préférence, chacun des mors de la pince présente, perpendiculairement au plan d'écartement et de rapprochement des mors, un relief s'étendant hors dudit plan, et muni d'une rainure d'allure circulaire pour recevoir un bord circulaire correspondant de la plaque au niveau de l'oeillet, le mors étant muni d'une encoche sensiblement semi-sphérique coaxiale à l'axe géométrique de ladite rainure circulaire, les encoches et rainures des deux mors étant symétriques par rapport au plan de contact des deux mors lorsque la pince est fermée. Preferably, each of the jaws of the clamp has, perpendicular to the plane of spacing and approximation of the jaws, a relief extending outside said plane, and provided with a groove of circular appearance to receive a corresponding circular edge of the plate at the level of the eyelet, the jaw being provided with a substantially semi-spherical notch coaxial with the geometric axis of said circular groove, the notches and grooves of the two jaws being symmetrical with respect to the contact plane of the two jaws when the clamp is closed.
De façon avantageuse, les mors peuvent être coudés au niveau de leur extrémité, en fonction des utilisations anatomiques recherchées. Advantageously, the jaws can be bent at their end, depending on the anatomical uses sought.
D'autres avantages et caractéristiques de l'invention apparaîtront à la lecture de la description suivante, faite à titre d'exemple non limitatif, et se référant au dessin annexé dans lequel

- la figure 3 représente une vue de détail de dessus de l'extrémité terminale des mors de la pince,
- la figure 4 représente une vue en section de l'extrémité terminale des mors de la pince.Other advantages and characteristics of the invention will appear on reading the following description, given by way of nonlimiting example, and referring to the appended drawing in which
FIG. 1 represents a side view of pliers according to the invention,
FIG. 2 represents a top view of this clamp before machining the end pieces,
FIG. 3 represents a detail view from above of the terminal end of the jaws of the clamp,
- Figure 4 shows a sectional view of the terminal end of the jaws of the clamp.
La pince ancillaire selon l'invention présente, d'une façon classique, deux branches 1 et 2 articulées autour d'un axe commun 3 et définissant deux mors 4 et 5. Des moyens de serrage du type à crans, usuels dans les pinces chirurgicales ont été représentés en 6. Lorsque le chirurgien referme la pince, les crans viennent en prise et la pince est bloquée. Un serrage supplémentaire, autorisé par l'élasticité des pinces, permet de débloquer les crans, d'une façon bien connue. The ancillary forceps according to the invention have, in a conventional manner, two branches 1 and 2 articulated around a common axis 3 and defining two jaws 4 and 5. Clamping means of the notch type, usual in surgical forceps have been shown in 6. When the surgeon closes the clamp, the notches come into engagement and the clamp is blocked. Additional tightening, authorized by the elasticity of the clamps, makes it possible to unlock the notches, in a well known manner.
Les mors 4,5 présentent des embouts 6,7, qui poursuivent les mors après un coude d'un angle choisi en fonction de considérations anatomiques, par exemple de 450
Les deux embouts sont symétriques par rapport au plan de symétrie de la pince passant par l'axe 3.The jaws 4.5 have end pieces 6.7, which follow the jaws after an elbow of an angle chosen according to anatomical considerations, for example 450
The two end pieces are symmetrical with respect to the plane of symmetry of the clamp passing through the axis 3.
Chaque embout présente une encoche semi-sphérique 8,9 dont la réunion forme un siège sphérique lorsque les deux mors ont été rapprochés. L'encoche 8,9 communique avec l'autre face de la pince par un passage semi-circulaire de faible épaisseur 14,15 dont la réunion forme un passage circulaire 16 de faible hauteur, qui sera coaxial à l'oeillet de la plaque à poser. Le diamètre du passage ainsi réalisé est très légèrement supérieur au diamètre du foret utilisé pour réaliser les avant-trous.Each end piece has a semi-spherical notch 8, 9 whose union forms a spherical seat when the two jaws have been brought together. The notch 8, 9 communicates with the other face of the clamp by a semi-circular passage of small thickness 14, 15, the meeting of which forms a circular passage 16 of low height, which will be coaxial with the eyelet of the plate to to pose. The diameter of the passage thus produced is very slightly greater than the diameter of the drill used to make the pilot holes.
Par ailleurs, chacun des deux embouts 6,7 présente, perpendiculairement au plan commun des deux embouts, un relief 10,11 dont la face interne, perpendiculaire à l'embout, présente une rainure 12,13, dont la hauteur est légèrement supérieure à la hauteur d'une plaque d'ostéosynthèse, et dont la profondeur varie de façon circulaire, comme on le voit bien sur la figure 3, le cercle géométrique ainsi défini ayant le même axe transversal au plan de l'embout que l'axe du passage et siège formé par la réunion des encoches 8,9, 14 et 15. In addition, each of the two end pieces 6,7 has, perpendicular to the common plane of the two end pieces, a relief 10,11 whose internal face, perpendicular to the end piece, has a groove 12,13, the height of which is slightly greater than the height of an osteosynthesis plate, and the depth of which varies circularly, as can be seen in FIG. 3, the geometric circle thus defined having the same axis transverse to the plane of the endpiece as the axis of the passage and seat formed by the meeting of notches 8, 9, 14 and 15.
Le rayon de ce cercle correspond sensiblement au rayon de la partie ou margelle circulaire de la plaque au niveau d'un oeillet.The radius of this circle corresponds substantially to the radius of the circular part or coping of the plate at the level of an eyelet.
Lorsque le chirurgien, ayant pratiqué la voie d'abord, a procédé à la réduction de la fracture et au ruginage découvrant la corticale osseuse de part et d'autre de la ligne de fracture à l'emplacement ou la plaque doit être posée, et après avoir, en cas de besoin, modelé la plaque, il saisit la plaque, par l'un de ses oeillets d'extrémité, dans la pince, de sorte que l'oeillet se trouve pris entre les deux mâchoires formées par les reliefs 10 et 11, la plaque étant reçue et serrée dans les rainures 12,13. Une fois, le cran 6 bloqué, la plaque d'ostéosynthèse est strictement solidaire de la pince ancillaire qu'elle prolonge. Dans cet état, le trou de l'oeillet est coaxial au passage 16 sensiblement cylindrique formé par la réunion des deux encoches semicirculaires 14,15. When the surgeon, having practiced the approach first, proceeded to the reduction of the fracture and the rouinage discovering the cortical bone on both sides of the line of fracture at the place where the plate must be posed, and after having, if necessary, shaped the plate, he grasps the plate, by one of its end eyelets, in the forceps, so that the eyelet is caught between the two jaws formed by the reliefs 10 and 11, the plate being received and clamped in the grooves 12,13. Once, the notch 6 blocked, the osteosynthesis plate is strictly secured to the ancillary forceps which it extends. In this state, the hole in the eyelet is coaxial with the substantially cylindrical passage 16 formed by the union of the two semicircular notches 14, 15.
Le chirurgien peut alors, avec la pince, présenter la plaque d'ostéosynthèse à l'emplacement désiré et l'appliquer contre l'os. Tout en maintenant la plaque en position, il peut ensuite procéder au forage de l'avant-trou, à travers le passage 16 puis le trou de l'oeillet, qui servent de guide au forêt et l'empêchent de dévier et ainsi de risquer de découper des particules métalliques dans l'oeillet. La dureté du métal formant l'embout est, de préférence, égale ou supérieure à la dureté du foret, de façon à éviter le découpage de particules. The surgeon can then, with the forceps, present the osteosynthesis plate in the desired location and apply it against the bone. While holding the plate in position, it can then proceed to drill the pilot hole, through passage 16 then the hole of the eyelet, which serve as a guide to the forest and prevent it from deflecting and thus risking to cut metal particles in the eyelet. The hardness of the metal forming the tip is preferably equal to or greater than the hardness of the drill, so as to avoid cutting of particles.
Le chirurgien, après avoir procédé au forage de l'avant-trou et retiré le foret, peut alors insérer la vis et commencer à visser la plaque par l'oeillet maintenu dans la pince jusqu'à ce que la tête sphérique de la vis soit reçue dans le siège en cuvette sphérique 8,9. The surgeon, after drilling the pilot hole and removing the drill, can then insert the screw and start to screw the plate by the eyelet held in the pliers until the spherical head of the screw is received in the seat in a spherical bowl 8.9.
Après avoir retiré la pince, le chirurgien finit de visser la vis dans l'oeillet, ce qui immobilise très vite la plaque dans la position voulue. Il peut ensuite procéder au forage des autres trous à travers la plaque maintenant immobilisée. Bien entendu, le cas échéant, il peut aussi utiliser une autre pince identique mais éventuellement coudée autrement, pour maintenir une autre extrémité de la plaque. After removing the forceps, the surgeon finishes screwing the screw into the eyelet, which quickly immobilizes the plate in the desired position. He can then proceed to drill the other holes through the plate now immobilized. Of course, if necessary, he can also use another identical clamp but possibly bent otherwise, to hold another end of the plate.
La pince selon l'invention peut être fabriquée par usinage de deux branches. Cependant, on peut également utiliser une pince à mors plats usuelle, éventuellement raccourcir les mors de cette pince et souder, au niveau desdits mors, les deux embouts 6,7. The clamp according to the invention can be produced by machining two branches. However, it is also possible to use a standard flat-jaw pliers, possibly shortening the jaws of this pliers and welding, at the level of said jaws, the two ends 6,7.
Par exemple les embouts 6,7, peuvent présenter, sur l'une des faces de la pince, deux prolongements en forme de parois semi-cylindriques 17,18 s'étendant transversalement à la pince. On y forme les reliefs 10,11, et les rainures 12,13 par usinage. Les encoches 8,9 et passages 14,15 sont usinés de l'autre côté de la pince. For example, the end caps 6,7 may have, on one of the faces of the clamp, two extensions in the form of semi-cylindrical walls 17,18 extending transversely to the clamp. The reliefs 10.11 are formed there, and the grooves 12.13 by machining. The notches 8, 9 and passages 14, 15 are machined on the other side of the clamp.
L'invention peut, bien entendu, faire l'objet de nombreuses variantes. Ainsi, par exemple, au lieu de présenter des reliefs s'étendant d'un côté de la pince, on peut réaliser, à l'aide de mors plus épais, des creusures directement dans la pince pour lui permettre de recevoir et de serrer l'extrémité d'une plaque d'ostéosynthèse, des encoches étant pratiquées pour former, lorsqu'elles sont réunies, le passage de guidage, et l'on comprend que toute variante rentre dans le cadre de l'invention dès lors qu'elle permet de donner à la pince la triple fonction de présentation de plaque permettant de serrer et de maintenir la plaque, de guidage de foret, et de maintien de la plaque pour le prévissage. The invention can, of course, be the subject of numerous variants. Thus, for example, instead of having reliefs extending on one side of the clamp, it is possible, using thicker jaws, to make recesses directly in the clamp to enable it to receive and tighten the end of an osteosynthesis plate, notches being formed to form, when joined, the guide passage, and it is understood that any variant falls within the scope of the invention as soon as it allows to give the pliers the triple function of plate presentation making it possible to tighten and maintain the plate, to guide the drill, and to hold the plate for pre-tightening.
