Description

Articulación de la banda pélvica en corsé de hiperextensión del tipo marco de Jewet o de tres puntos de apoyo.Articulation of the pelvic band in corset hyperextension of the Jewet frame type or three-point support for.

El sector de la técnica de esta invención es el de los corsés de hiperextensión tipo marco de Jewet. Estos corsés tienen como característica que poseen una estructura formada por una banda pélvica, un apoyo pectoral, dos laterales y un apoyo trasero. El fundamento de este corsé consiste en limitar o inmovilizar al paciente entre los tres apoyos, siempre en referencia a patologías de la columna vertebral.The technical sector of this invention is the of Jewet frame type hyperextension corsets. These corsets they have the characteristic that they have a structure formed by a pelvic band, a pectoral support, two lateral and a support rear. The basis of this corset is to limit or immobilize the patient between the three supports, always in reference to pathologies of the spine.

Sin embargo, los corsés conocidos tienen un inconveniente, y se deriva del hecho de que son habitualmente fijos, es decir, la banda pélvica está unida en forma rígida sobre las pletinas laterales, lo cual genera incomodidades para los pacientes, a la hora de sentarse y permanecer en sedestación, pues en dicha posición de máxima extensión del corsé, apoya y presiona la banda pélvica sobre la pelvis y la parte superior de los muslos del paciente.However, known corsets have a inconvenient, and derives from the fact that they are usually fixed, that is, the pelvic band is rigidly attached on the side plates, which creates discomfort for the patients, at the time of sitting and staying in sitting, because in this position of maximum extension of the corset, support and press the pelvic band on the pelvis and upper thighs of the patient.

Otra opción es que exista una articulación practicable retenida por un muelle. En este caso se trata de un corsé distinto y la articulación permite sentarse con relativa comodidad al disminuir mucho la extrema presión sobre muslos y pelvis, pero la eficacia del corsé decae momentáneamente, pues la banda pélvica articulada impide la fijación rígida entre los tres puntos de apoyo sobre el cuerpo del paciente, tal y como se haya previsto en la prescripción facultativa.Another option is that there is a joint practicable retained by a pier. In this case it is a different corset and the joint allows you to sit with relative comfort by greatly reducing extreme pressure on thighs and pelvis, but the effectiveness of the corset drops momentarily, as the articulated pelvic band prevents rigid fixation between the three support points on the patient's body, as it is provided in the optional prescription.

Explanation of the invention and an embodiment

El corsé de hiperextensión del tipo de marco de Jewet o de tres puntos de apoyo, tiene como característica esencial, tal y como se ha explicado, que poseyendo una estructura en la que destaca apoyo pectoral y una banda pélvica, se sujeta en un tercer punto, la espalda del individuo, mediante una fijación por cinchas o similar. La banda pélvica es problemática porque al quedar en máxima extensión por la acción de sendos muelles en sendas cabezas 2 de dicha banda pélvica que presiona pelvis y muslos del usuario, o bien para evitar esto, se fija.The hyperextension corset of the frame type of Jewet or three support points, has the characteristic essential, as explained, that owning a structure which highlights chest support and a pelvic band, is held in a third point, the individual's back, through a fixation by straps or similar. The pelvic band is problematic because at remain in maximum extension by the action of two docks in two heads of said pelvic band that presses pelvis and thighs of the user, or to avoid this, is fixed.

Cada cabeza de la banda pélvica 2 se dispone sobre la correspondiente cabeza de cada pieza lateral 1, de modo que se unen mediante un eje formado por el tornillo 7, que permite la articulación entre cada cabeza de la banda pélvica 2 y la correspondiente cabeza de las piezas laterales 1. Dispone ahí un muelle, que se une a ambas partes por la parte interna o de las partes encaradas de cada pieza lateral y banda pélvica. Se limita en cada articulación el ámbito de giro con respecto al eje mediante la disposición de sendos vaciados que constituye cada corredera 11, ésta dispuesta en cada cabeza de la banda pélvica 2 en cooperación con sendos pivotes 12 de las piezas laterales 1. Esto produce un efecto limitador del ámbito de movimiento de la banda pélvica unos 15°, si bien es posible fijar dicha banda pélvica. Dicha fijación se produce en forma preferente en una de dos posiciones, que se determinan por sendos tornillos 9 que pueden fijarse en cada cabeza 1 de la pieza lateral y se insertan a través de cada orificio 10 de la cabeza de la banda pélvica 2. La fijación tiene lugar por el hecho de que el tornillo 9 se inserte en la tuerca correspondiente, ya que su cabeza posee una dimensión coincidente, siempre algo menor, con alguno de los huecos a tal fin de la fijación 10, que además están dotados de una unión que permite el paso del tornillo de una posición a otra cuando no se halla embutido en alguno de los huecos de la fijación 10. Ello facilita grandemente los ajustes para determinar la comodidad del usuario, siempre según ajuste llevado a cabo por el ortopeda según instrucciones del facultativo. El tornillo 9 para la fijación 10, se inserta en una tuerca lateral empotrable grafilada 8 que se embute en la cabeza de la pieza lateral 1.Each head of the pelvic band 2 is arranged on the corresponding head of each side piece 1, so which are joined by an axis formed by screw 7, which allows the joint between each head of the pelvic band 2 and the corresponding head of the side pieces 1. There is a spring, which joins both sides by the internal part or of the facing parts of each side piece and pelvic band. Is limited in each joint the scope of rotation with respect to the axis by the disposition of two emptied ones that constitutes each slide 11, this arranged in each head of the pelvic band 2 in cooperation with two pivots 12 of the side pieces 1. This produces a limiting effect of the range of motion of the pelvic band about 15 °, although it is possible to fix said pelvic band. Such fixation occurs preferentially in one of two positions, which determined by two screws 9 that can be fixed on each head 1 of the side piece and are inserted through each hole 10 of the head of the pelvic band 2. Fixation takes place by the because the screw 9 is inserted into the corresponding nut, since its head has a matching dimension, always something minor, with any of the holes for the purpose of fixing 10, which They are also equipped with a joint that allows the passage of the screw from one position to another when it is not embedded in any of the fixing holes 10. This greatly facilitates adjustments for determine user comfort, always according to the adjustment carried out by the orthopedist according to the doctor's instructions. The screw 9 for fixing 10, is inserted into a side nut recessed grafilada 8 that is embedded in the head of the piece lateral 1.

La fijación 10 y la corredera 11 se hallan preferentemente en oposición con respecto al eje, lo que facilita la estabilidad del conjunto.The fixing 10 and the slide 11 are preferably in opposition to the axis, which facilitates the set stability

El eje de articulación de ambas partes, cabeza de los laterales 1 y cabeza de la banda pélvica 2, tiene lugar por una tuerca central grafilada 6 que se embute por un golpe y que posee una rosca central para un tornillo 7. Dicha tuerca tiene una parte 18 que sobresale del enrase de la cabeza del brazo lateral, constituyendo a su vez una superficie de fricción 19 entre ambas partes. La fijación se lleva a cabo por el paso del tornillo 7 que constituye el eje por el agujero central 5 de las cabezas de la banda pélvica. También la tuerca 8 tiene una parte 20 que sobresale de la cabeza de la pletina lateral 1, constituyendo la superficie 21 de dicha tuerca 8, la entrada de rosca sobre la que aprieta el tornillo 9. a través de la inserción en alguno de los huecos de la fijación 10 de las cabezas de la banda pélvica 2.The axis of articulation of both parts, head of the lateral 1 and head of the pelvic band 2, takes place by a central nut grafilada 6 that is embedded by a blow and that has a central thread for a screw 7. Said nut has a part 18 protruding from the enrase of the head of the lateral arm, constituting in turn a friction surface 19 between the two parts The fixing is carried out by the passage of screw 7 which constitutes the axis through the central hole 5 of the heads of the pelvic band Also the nut 8 has a protruding part 20 of the head of the lateral plate 1, constituting the surface 21 of said nut 8, the thread inlet on which the screw 9. through the insertion in any of the holes in the 10 fixation of the pelvic band heads 2.

El muelle 3 se dispone interiormente entre dos puntos 16, 17, de las partes encaradas de cada cabeza de cada pieza lateral del corsé y cada cabeza de la banda pélvica 2, y preferentemente se le dota de forma de muelle espiral plano, disponiendo dichas partes encaradas, respectivamente, una entrada de muelle 16 formada por un orificio dispuesto en las cabezas de las pieza laterales 1, y en alguna de las entradas de muelle 17 dispuestas en la parte contigua de las cabezas de la banda pélvica 2.The spring 3 is arranged internally between two points 16, 17, of the facing parts of each head of each piece side of the corset and each head of the pelvic band 2, and preferably it is provided with a flat spiral spring shape, arranging said facing parts, respectively, an entry of spring 16 formed by a hole arranged in the heads of the side pieces 1, and in any of the spring entries 17 arranged in the contiguous part of the pelvic band heads two.
