Abstract

The invention relates to forceps for carrying an implant for surgical use allowing grasping of artificial lenses for their intraocular positioning. It is composed of a tube 1 whose end comprises a lateral slot, of a stop 3 and of a chuck 2 sliding within the tube whose travel is limited by the stop. The system of connection between the tube and its chuck is elastic, and ensures, in the quiescent state, a constant pressure of the chuck on the stop, which allows the implant to be retained. The use of these forceps is not limited. They are in particular intended for grasping an implant for the posterior chamber comprising an optical lens 13 drilled with an orifice 11 on the edge receiving the stop 3, and a flexible handle allowing pushing back with respect to the hole via the chuck 2.

Description

La présente invention est une pince porte implant pour lentille intra oculaire ou cristallin artificiel. The present invention is an implant holder clamp for intraocular lens or artificial lens.

Actuellement, il existe plusieurs types de pinces porte implant dont le système de préhension est différent de celui exposé icio
Cette pince se compose d'un tube (1) de 7/10 de Enni de # dans lequel coulisse un mandrin (2) de 5/îo de mm de 0. L'extrêmité du tube présente une lumière latérale de 1 mm de longueur ne lais sant que l'épaisseur du tube, La pointe est recourbée à 900 par rapport à l'axe du tube, et forme une butée (3) pour le mandrin dont l'extremité est elle-meme sectionnée à 900 par rapport à son axe.Cette butée est cylindrique, à bout mousse, et mesure 4110 de mm de hauteur sur un diamètre de 2/10 de mmO L'extremité de l'ensemble tube-mandrin est coudée selon un rayon de courbure (4) de 11 ordre de 20 mm. Le départ de la courbe débute à 3 mm de l'ex- tremité et s'arrête de telle sorte que l'angle entre la partie rectiligne de lsextrtmité et le reste de l'ensemble fasse 1300 à 1500. Currently, there are several types of implant holder pliers whose gripping system is different from that shown here
This clamp consists of a tube (1) of 7/10 of Enni of # in which slides a mandrel (2) of 5/10 mm of 0. The end of the tube has a lateral lumen of 1 mm in length leaving only the thickness of the tube, the point is bent at 900 relative to the axis of the tube, and forms a stop (3) for the mandrel whose end is itself cut at 900 relative to its This stop is cylindrical, with a foam tip, and measures 4110 mm in height on a diameter of 2/10 mmO The end of the tube-mandrel assembly is bent according to a radius of curvature (4) of 11 order 20 mm. The start of the curve begins at 3 mm from the end and stops so that the angle between the rectilinear part of the end and the rest of the assembly is 1300 to 1500.

Ce système ainsi constitué est rendu solidaire d'un losange déformable. Ce losange déformable peut etre constitué de trois manieres
Première manière : Il se compose de 4 lamelles métalliques dont les angles de la petite diagonale sont articulés par un axe de rotation (5)s et dont les angles de la grande diagonale sont articulés par une petite plaque métallique (6 & 8) présentant un axe à chaque extrémité, Chaque plaque est perforée d'un trou.This system thus formed is made integral with a deformable diamond. This deformable diamond can be made in three ways
First way: It consists of 4 metal strips whose angles of the small diagonal are articulated by an axis of rotation (5) s and whose angles of the large diagonal are articulated by a small metal plate (6 & 8) having a axis at each end, Each plate is perforated with a hole.

L'un correspond au # du cylindre g l'autre au # du mandrine Un ressort lame (7) s'interpose dans ce losange de telle sorte que son action ait tendance à agrandir en permanence la petite diagonale. Ce ressort présente une lumière centrale laissant passer lsensemble tube-mandrin. Dans ce cas, le tube est fixé à une plaquette (6) et le mandrin à l'autre plaquette (8). One corresponds to the # of the cylinder g the other to the # of the mandrel A leaf spring (7) is interposed in this rhombus so that its action tends to constantly enlarge the small diagonal. This spring has a central lumen allowing the tube-mandrel assembly to pass. In this case, the tube is fixed to a plate (6) and the mandrel to the other plate (8).

Deuxième manière : L'extremité correspondant au tube est constituée de la mme manière, mais les deux lamelles métalliques sont réunies par une lame de ressort de forme semi elliptique qui a également comme action permanente d'écarter les deux lamelles. Dans ce cas, le tube est fixé comme précédemment, et le mandrin est fixé sur le ressort au travers d'un trou situé dans l'axe de symétrie. Second way: The end corresponding to the tube is made in the same way, but the two metal strips are joined by a spring leaf of semi-elliptical shape which also has the permanent action of spreading the two strips. In this case, the tube is fixed as above, and the mandrel is fixed on the spring through a hole located in the axis of symmetry.

Troisième manière : Une lamelle ressort ovalaire unique forme l'ensemble de liaison tube mandrine
Dans les trois cas, le mode de fixation peut entre différent : soit soudé, soit serti, soit vissé, permettant alors un échange aisé de l'ensemble tube-mandrin0
Le montage est effectué de telle façon que la pince se présente au repos, en position fermée, et la force du ressort est calculée de façon que la pression au repos du mandrin sur la butée soit suffisante pour maintenir l'implant sans endomager.Third way: A single oval spring strip forms the mandrel tube connection assembly
In all three cases, the fixing method can be different: either welded, crimped, or screwed, allowing easy exchange of the tube-mandrel assembly.
The assembly is carried out in such a way that the clamp is at rest, in the closed position, and the spring force is calculated so that the pressure at rest of the mandrel on the stop is sufficient to maintain the implant without damaging it.

L'ouverture de la pince s'effectue par pression sur les deux lamelles métalliques (9) et (10). The clamp is opened by pressing on the two metal strips (9) and (10).

L'utilisation de cette pince n'est pas limitative, mais cette pince est particulièrement destinée à la préhension d'implant de chambre postérieure comportant une lentille optique (13) percée d'un orifice (il) en périphérie recevant la butée (3), et d'une anse flexible (12) permettant d'être repoussée en regard du trou par le mandrin (2)o
Cette pince offre plusieurs avantages Un encombrement plus réduit : 7/10 de mm de # ; une préhension automatique à pression constante et déterminée de maniera à ce qu'elle soit suffisante et quelle n'entraîne pas de détérioration de l'implant ou de l'anse, contrairement aux autres types de pinces (figure 4) avec lesquelles il faut exercer une pression manuelle presque toujours excessive dans la crainte de-lacher la prise lors de lvintroduction de l'implant, et dont le système a pour inconvénient le risque dtendommager l'anse et la pince et un encombrement plus important. Cettepréhension laisse une plus grande mobilité dans les gestes lors de l'introduction de 1 'im- plant, car elle ne nécessite aucun effort pour tenir l1implant, contrairement aux autres systèmes (Figure 4) e
Mode d'emploi : Ouvrir la pince en appuyant sur les lamel les (9) et (10) ; pousser l'anse (12) de l'implant avec l'ex- tremité du mandrin (2) ; introduire la butée (3) dans lXorifice (il) de l'implant ; reltcher la pression0 L'implant tient alors seul à lXextrêmité de la pince ; pour libérer l'implant, il suffit d'appuyer sur les lamelles (9) et (10) The use of this clamp is not limiting, but this clamp is particularly intended for gripping a posterior chamber implant comprising an optical lens (13) pierced with an orifice (it) at the periphery receiving the stop (3) , and a flexible handle (12) allowing it to be pushed back opposite the hole by the mandrel (2) o
This clamp offers several advantages A smaller footprint: 7/10 mm of #; an automatic gripping at constant and determined pressure so that it is sufficient and which does not lead to deterioration of the implant or the handle, unlike other types of forceps (Figure 4) with which it is necessary to exercise a manual pressure almost always excessive in the fear of releasing the grip during the introduction of the implant, and whose system has the disadvantage of the risk of damaging the handle and the clamp and a greater bulk. This grip leaves greater mobility in gestures during the introduction of the implant, because it requires no effort to hold the implant, unlike other systems (Figure 4) e
Instructions for use: Open the pliers by pressing on the lamel (9) and (10); push the handle (12) of the implant with the end of the mandrel (2); insert the stop (3) into the orifice (il) of the implant; relieve pressure0 The implant then holds alone at the end of the forceps; to release the implant, simply press the strips (9) and (10)
