Abstract

The device has a support cradle (1) supported by a mast (2). The mast is free to rotate and flex relative to the cradle. The mast is provided on a base (3) and adjustable and lockable in height. The base is flexibly hinged, and limited by a stop, where the base itself is supported on a same operating table (7) such that the base is interdependent on the operating table by a fixing unit provided on the operating table. A set of flexible ends of the mast is provided with multiple spiral wings.

Description

-1- La présente invention, à pour objet un dispositif de positionnement qui est destiné à soutenir l'avant bras d'un praticien opératoire, de façon à ce que celui-ci ait une référence spatiale de son geste, tout en garantissant le libre choix de l'orientation de celui-ci. Traditionnellement, le geste opératoire se fait en surplomb du patient, occasionnant une posture en porte à faux importante du bras par rapport au bord de la table d'opération. Cela entraîne de l'imprécision, de la crispation, ainsi que la fatigue musculaire pour le chirurgien, surtout, lors d'interventions longues. Le dispositif selon l'invention, permet de remédier à cette situation par le fait qu'il comporte , selon la première caractéristique, un berceau de repos en forme de U,adapté à la configuration de l'avant bras , destiné à soutenir l'avant-bras du praticien à un niveau proche de son coude. Ce berceau, en appui sous l'avant-bras est supporté par un mât flexible, de hauteur réglable et verrouillable, lui-même en appui sur la table d'opération. Ce mât,articulé en rotation par rapport au berceau, repose , en partie basse , sur une 15 embase , servant de fixation ainsi que de référence spatiale, tout en laissant libre son orientation tout azimut par flexion. Le berceau, reste libre en rotation par une fixation tournante, axée sur le mât. Le mât est flexible, en partie haute et basse, assurant le confort et libérant les mouvements du bras du praticien. 20 La partie haute et basse du mât, bien que flexible tout azimut, occasionne, de par sa forme à ailettes multiples ou spiralée, un effet butée, limitant l'incidence de l'orientation de celui-ci, afin de sécuriser le champ opératoire. The present invention relates to a positioning device which is intended to support the forearm of a surgical practitioner, so that it has a spatial reference of his gesture, while ensuring the free choice of the orientation of it. Traditionally, the surgical procedure is overhanging the patient, causing a significant cantilever posture of the arm relative to the edge of the operating table. This leads to imprecision, tension, and muscle fatigue for the surgeon, especially during long interventions. The device according to the invention makes it possible to remedy this situation by the fact that it comprises, according to the first characteristic, a U-shaped rest cradle, adapted to the configuration of the forearm, intended to support the practitioner's forearm at a level close to his elbow. This cradle, supported under the forearm is supported by a flexible mast, height adjustable and lockable, itself supported on the operating table. This mast, articulated in rotation relative to the cradle, rests, in the lower part, on a base, serving as fixing and spatial reference, while leaving free its entire orientation by bending. The cradle, remains free in rotation by a rotating attachment, focused on the mast. The mast is flexible, at the top and bottom, ensuring comfort and releasing the movements of the practitioner's arm. The upper and lower part of the mast, although flexible in all directions, causes, due to its multiple finned or spiral shape, a stopping effect, limiting the incidence of the orientation of the latter, in order to secure the operating field. .

Le dessin annexé, illustre l'invention. La figure 1 représente la vue de coté du dispositif en position libre La figure 2 représente la vue de coté du dispositif en position limitée The attached drawing illustrates the invention. FIG. 1 represents the side view of the device in the free position FIG. 2 represents the side view of the device in a limited position

En référence à ce dessin, le dispositif comporte un berceau de soutien (1) de l'avant bras, relié 30 en partie haute par une liaison tournante (4) à un mât flexible (2) de hauteur réglable et verrouillable. Ce mât s'articule de manière flexible sur une embase (3) par une liaison (5) limitée en débattement d'inclinaison par sa forme faisant butée (6). L'embase (3) restant fixée sur la table opératoire (7) par moyen classique adapté. 35 Referring to this drawing, the device comprises a support cradle (1) of the forearm, connected in the upper part by a rotating connection (4) to a flexible mast (2) of adjustable height and lockable. This mast is articulated flexibly on a base (3) by a connection (5) limited in inclination travel by its abutment shape (6). The base (3) remaining fixed on the operating table (7) by conventional means adapted. 35

Dans la forme de réalisation selon fig 1 et fig 2 les liaisons sont mécaniques , mais aussi flexibles de façons viscoélastiques par l'utilisation de matériaux tels que des câbles,des soufflets , des aciers ressort , des matières plastiques ou composites . Ainsi le mât est 40 constitué dans ses extrémités de matériaux déformables par flexion. Les extrémités flexibles du mât sont dotées d'une forme à ailettes multiples ou spiralée. In the embodiment according to fig 1 and fig 2 the connections are mechanical, but also viscoelastically flexible by the use of materials such as cables, bellows, spring steels, plastics or composites. Thus the mast is constituted in its ends by deformable materials by bending. The flexible ends of the mast have a multi-fin or spiral shape.

Il va de soit, que la présente réalisation n'est que l'une des formes non limitatives de l'invention. 25 It goes without saying that the present embodiment is only one of the non-limiting forms of the invention. 25
