Description
Piece à main à slip-joint destinee à etre emmanchée en bout d'un micro-moteur On utilise generalement en dentisterie et en chirurgie des pieces à main fixe es sur un emmanchement d'un micro-moteur par un type de fixation appelé slip- joint . Slip-joint handpiece intended to be fitted at the end of a micro-motor In dentistry and surgery, fixed handpieces are generally used on a fitting of a micro-motor by a type of fixing called a slip-joint.
Cependant, ces dispositifs d'accrochage presentent un inconvénient important; en effet, le moteur ne peut pas etre passe au stérilisateur, de sorte qu'il y a un danger de souillure meme si la piece à main a ete stériliseé. Pour cela il suffit que la main gantee du praticién vienne au contact du moteur, par exemple, lors de la fixation de la piece à main. However, these attachment devices have a significant drawback; indeed, the motor cannot be sterilized, so that there is a danger of soiling even if the handpiece has been sterilized. For this, it suffices that the gloved hand of the practitioner comes into contact with the motor, for example, when fixing the handpiece.
En conséquence, l'invention se propose de fournir une piece à main stérilisable permettant d'empecher le contact de la main du praticien avec le moteur, et de maintenir ainsi la sterilisation de la piece à main. Consequently, the invention proposes to provide a sterilizable handpiece making it possible to prevent the contact of the practitioner's hand with the motor, and thus to maintain the sterilization of the handpiece.
L'invention concerne une piece à main à slip-joint, destinee à etre emmanchée en bout d'un micro-moteur caractérisée en ce qu'elle est prolongée, du cote du moteur, par une douille destinée à recouvrir au moins en partie le moteur, et pouvant comprendre à son intérieur un ergot destiné à coopérer avec un dispositif d'accrochage. The invention relates to a slip-joint handpiece, intended to be fitted at the end of a micro-motor, characterized in that it is extended, on the side of the motor, by a sleeve intended to cover at least part of the engine, and may include inside it a lug intended to cooperate with a hooking device.
L'invention sera bien comprise en se referant à la des cription suivante faite à titre d'exemple ainsi qu'au dessin annexé dans lequel la fig. 1 représente une coupe d'ensemble d'une forme d'execution de la piece à main montee sur le moteur; la fig. 2 représente une vue de l'emmanchement du moteur; la fig. 3 représente une coupe de l'arrière de la piece a main; la fig. 4 represente une coupe transversale de la piece à main montee sur le moteur. The invention will be better understood by referring to the following description given by way of example as well as to the appended drawing in which FIG. 1 shows an overall section of one form of execution of the handpiece mounted on the motor; fig. 2 shows a view of the engine fitting; fig. 3 shows a section of the back of the handpiece; fig. 4 shows a cross section of the handpiece mounted on the motor.
La piece à main 1 comporte un corps tubulaire creux 2 qui vient s'emmancher sur l'emmanchement 3, appelé aussi douille-slip, qui termine le micro-moteur 4. Ladite douille-slip 3 possede une rainure longitudinale 5 dans laquelle est logee une lame ressort 6. Cette lame ressort 6 se termine par une partie annelée 7 logee dans une gorge circulaire 8 de la douille-slip 3. The handpiece 1 comprises a hollow tubular body 2 which is fitted onto the fitting 3, also called slip-socket, which terminates the micro-motor 4. Said slip-socket 3 has a longitudinal groove 5 in which is housed a leaf spring 6. This leaf spring 6 ends in a ringed part 7 housed in a circular groove 8 of the sleeve-slip 3.
La lame ressort 6 porte, vers l'une de ses extrémités, un ergot 9 qui vient se loger dans une gorge circulaire intérieure 10 du corps tubulaire 2. Un poussoir 11 peut etre disposé sur le moteur pour permettre, en appuyant sur l'extrémité de la lame ressort 6, d'abaisser l'ergot 9. The spring blade 6 carries, towards one of its ends, a lug 9 which is housed in an inner circular groove 10 of the tubular body 2. A pusher 11 can be arranged on the motor to allow, by pressing on the end of the spring blade 6, to lower the lug 9.
Le corps tubulaire 2 de ladite piece à main 1 se prolonge par une douille 12 dont elle est solidaire, et qui vient recouvrir, au moins en partie, le micro-moteur 4. The tubular body 2 of said handpiece 1 is extended by a sleeve 12 to which it is integral, and which covers, at least in part, the micro-motor 4.
Cette douille 12 permet ainsi d'éviter le contact de la main du pratioien avec le micro-moteur 4, cause de souillure de la piece à main 1. This socket 12 thus makes it possible to avoid contact of the practitioner's hand with the micro-motor 4, which causes the handpiece 1 to be soiled.
Afin de permettre de degager la piece à main 1 de la douille-slip 3, on a prevu de disposer dans la partie avant de la douille 12, un ergot 13 faisant saillie dans la gorge intérieure 10. Lorsque la pièce 7 main tourne sur elle-même autour de l'axe du moteur 4, l'ergot 13 peut etre amene à appuyer sur l'ergot 9, ce qui permet la libé- ration de la piece à main 1. In order to allow the handpiece 1 to be disengaged from the slip-sleeve 3, provision has been made to place in the front part of the sleeve 12, a lug 13 projecting into the inner groove 10. When the handpiece 7 turns on it -even around the axis of the motor 4, the lug 13 can be brought to press on the lug 9, which allows the release of the handpiece 1.
Ainsi pour accrocher la piece à main 1 sur la douilleslip 3, il suffit de ne pas mettre les deux ergots 9 et 13 en face l'un de l'autre. Pour degager la piece à main 1, il suffit de la faire tourner jusqu'à amener lesdits ergots 9 et 13 en contact. So to hang the handpiece 1 on the socketslip 3, it suffices not to put the two lugs 9 and 13 opposite one another. To release the handpiece 1, it suffices to rotate it until said lugs 9 and 13 come into contact.
I1 va de soi que l'invention ne se limite pas à la piece à main décrite ci-dessus. Toute piece à main, quel que soit le dispositif de fixation qu'elle utilise, pourra etre prolongée par une douille protectrice empêchant le contact du micro-moteur 4 avec la main du praticien et, par lä, avec la piece à main. On pourra munir le dispositif d'un systeme de fixation commandé, soit à partir du corps de la piece à main, soit à partir de la douille protectrice soit à partir du micro-moteur, soit à partir de tout autre endroit. I1 goes without saying that the invention is not limited to the handpiece described above. Any handpiece, regardless of the attachment device it uses, may be extended by a protective sleeve preventing contact of the micro-motor 4 with the practitioner's hand and, thereby, with the handpiece. The device may be provided with a fastening system controlled either from the body of the handpiece, or from the protective sleeve or from the micro-motor, or from any other place.
