SECTOR DE LA TÉCNICATECHNICAL SECTOR

La presente invención se refiere a un soporte o accesorio para angiógrafos.The present invention refers to a support or accessory for angiographers.

El objeto de la invención es proporcionar un dispositivo para intervenciones en angiógrafo que permita un posicionamiento adecuado y estable del brazo del paciente durante la intervención, aplicable a ambos brazos, y que paralelamente ofrece una mesa auxiliar que sirva de apoyo para el brazo del propio cirujano, en orden a descansar el mismo durante la operación, y conseguir una mayor precisión, así como determinar adicionalmente un medio de apoyo para los diferentes instrumentos utilizados durante la misma, si bien podría ser utilizada igualmente para otros usos.The object of the invention is to provide a device for angiography interventions that allows an adequate and stable positioning of the patient's arm during the intervention, applicable to both arms, and that at the same time offers an auxiliary table that serves as support for the surgeon's own arm. , in order to rest it during the operation, and achieve greater precision, as well as additionally determine a means of support for the different instruments used during the same, although it could also be used for other uses.

ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION

Un angiógrafo es un equipo médico que utiliza rayos X y sistemas digitales para sustraer las estructuras que no son de interés dejando visibles los vasos sanguíneos (arterias y venas) del organismo.An angiograph is a medical team that uses X-rays and digital systems to subtract structures that are not of interest, leaving the blood vessels (arteries and veins) of the body visible.

Durante las operaciones a realizar puede precisarse que el paciente disponga el brazo en distintas posiciones que sean requeridas, no disponiéndose hasta la fecha de accesorios que ofrezcan estas prestaciones y que a la vez sean fácilmente implantables sobre el angiógrafo sin que supongan un estorbo a la hora de intervenir, o sean adecuadas desde el punto de vista funcional del cirujano o para el uso de quirófanos.During the operations to be performed, it may be necessary for the patient to have the arm in different positions as required, and to date there are no accessories that offer these benefits and that at the same time are easily implantable on the angiograph without being a hindrance at the time. to intervene, or are suitable from the functional point of view of the surgeon or for the use of operating rooms.

EXPLICACIÓN DE LA INVENCIÓNEXPLANATION OF THE INVENTION

El soporte para uso en angiógrafo que se preconiza resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, en base a una solución sencilla pero eficaz. The support for use in angiography that is recommended fully solves the aforementioned problems, based on a simple but effective solution.

Para ello, y de forma más concreta, el dispositivo de la invención se materializa en un conjunto, en el que participan dos elementos fundamentales; un soporte inmovilizador y regulador de la posición del brazo, y una mesilla auxiliar que permite posar las manos al cirujano durante las operaciones para descansar el mismo, así como determinar un elemento que sirva adicionalmente como medio para apoyo del instrumental utilizado.For this, and more specifically, the device of the invention is embodied in a set, in which two fundamental elements participate; an immobilizing support and regulator of the position of the arm, and an auxiliary table that allows the surgeon to rest his hands during operations to rest it, as well as to determine an element that additionally serves as a means of supporting the instruments used.

Ambos dispositivos estarán obtenidos en materiales radiológicamente compatibles, preferentemente material composite anti-bacteriano y plásticos de fabricación aditiva mediante impresora 3D.Both devices will be obtained from radiologically compatible materials, preferably antibacterial composite material and additive manufacturing plastics using a 3D printer.

Ambos dispositivos están destinados a inmovilizarse junto al borde de la colchoneta del angiógrafo, median inserción de su base bajo dicha colchoneta, quedando perfectamente estabilizados sin necesidad de mecanismos sobresalientes que pudieran limitar las maniobras del cirujano.Both devices are intended to be immobilized next to the edge of the angiographer's mat, inserting their base under said mat, remaining perfectly stabilized without the need for protruding mechanisms that could limit the surgeon's maneuvers.

En cuanto al soporte de brazo, éste está constituido a partir de un base laminar que, como acaba de decirse está destinada a insertarse bajo la colchoneta del angiógrafo en correspondencia con el borde de la misma a la altura del brazo del paciente a estabilizar en la posición que se estime conveniente, siendo aplicable sobre ambos lados de la colchoneta, es decir para el uso en ambos brazos, plataforma a la que se vincula un elemento en funciones de soporte para el brazo, de configuración anatómica, aplanada, curvo cóncava, en la que se define un tramo central y mayoritariamente recto con sendos acodamientos extremos a la altura del codo y mano del usuario, donde se definen sendos tramos inclinados inferiormente, contando el tramo destinado a recibir a la mano con una banda o correa que se adaptará transversalmente a la palma de la mano.As for the arm support, it is made up of a laminar base which, as has just been said, is intended to be inserted under the angiographer's mat in correspondence with its edge at the height of the patient's arm to be stabilized in the position that is deemed convenient, being applicable on both sides of the mat, that is, for use on both arms, platform to which an element is linked that acts as support for the arm, with an anatomical, flattened, concave curved configuration, in which defines a central and mostly straight section with two extreme bends at the height of the user's elbow and hand, where two sections are defined that are inclined inferiorly, counting the section destined to receive the hand with a band or strap that will be adapted transversely to the palm of the hand.

El citado soporte para el brazo se vincula a la base a través de una articulación con medios de bloqueo y desbloqueo a través de un mando accesible inferiormente, a modo de embrague, que permite regular el grado de inclinación del soporte con respecto a la base de acuerdo a dos ejes de basculación, un eje de basculación horizontal, y un eje de giro vertical. Opcionalmente, la articulación podría incorporar un tercer eje de giro del soporte, de balanceo del mismo, de acuerdo con un eje de giro perpendicular a los dos anteriores. Said support for the arm is linked to the base through a joint with locking and unlocking means through a control accessible from below, in the form of a clutch, which allows the degree of inclination of the support to be adjusted with respect to the base. according to two pivot axes, a horizontal pivot axis, and a vertical pivot axis. Optionally, the articulation could incorporate a third axis of rotation of the support, for its rocking, according to an axis of rotation perpendicular to the previous two.

Como se decía, estas dos regulaciones se posibilitan mediante accionamiento del correspondiente mando, a través del que igualmente se bloquea.As was said, these two adjustments are made possible by activating the corresponding control, through which it is also blocked.

Para facilitar las maniobras de transporte desde la zona de almacenamiento del soporte al quirófano, la base del mismo contará con un vaciado determinante de un asa de transporte manual.To facilitate transport maneuvers from the support storage area to the operating room, its base will have a decisive emptying of a manual transport handle.

Por su parte, la mesa auxiliar está obtenida a partir de dos piezas laminares de perfil en "L” que están parcialmente superpuestas entre sí formando un perfil en

cuya rama inferior define el medio de estabilización de la misma mediante inserción bajo la colchoneta del angiógrafo, mientras que la rama horizontal de la pieza complementaria define la superficie de apoyo auxiliar, incluyendo estas dos piezas medios de regulación posicional vertical relativa entre las mismas a partir de unas guías complementarias y un mecanismo de liberación y bloque relativo entre las dos piezas de forma selectiva.For its part, the auxiliary table is obtained from two laminar pieces with an "L" profile that are partially superimposed on each other, forming a profile in

whose lower branch defines the means of stabilizing it by inserting it under the angiographer's mat, while the horizontal branch of the complementary piece defines the auxiliary support surface, these two pieces including relative vertical positional adjustment means between them from of complementary guides and a release mechanism and relative block between the two pieces selectively.

A partir de esta estructuración, la mesa auxiliar se puede colocar en diferentes posiciones, como por ejemplo en correspondencia con el tronco inferior del paciente, es decir de cintura para abajo, y la base del apoyabrazos bajo la espalda del paciente. De modo que la primera evita que el cirujano se apoye sobre las piernas del paciente durante la operación, mientras que el soporte de brazo permite adaptar éste a las posiciones específicas que requiera dicha operación.Based on this structure, the auxiliary table can be placed in different positions, such as, for example, in correspondence with the lower body of the patient, that is to say from the waist down, and the base of the armrest under the patient's back. So that the first prevents the surgeon from leaning on the patient's legs during the operation, while the arm support allows it to be adapted to the specific positions required by said operation.

El dispositivo en situación inoperante podrá adaptar una ocupación volumétrica mínima, al encajar mayoritariamente el soporte de brazo en el seno de la mesilla auxiliar, la cual puede plegarse hasta su posición de menor altura, en la que su ocupación volumétrica es menor.The device in an inoperative situation will be able to adapt a minimum volumetric occupation, as the arm support mostly fits inside the auxiliary table, which can be folded to its lowest position, in which its volumetric occupation is less.

REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION

A la vista de las figuras reseñadas, y en especial de la figura 1 puede observarse como en el dispositivo de la invención participan dos elementos complementarios que se suministran formando un conjunto de mínima volumetría, en el que participa un soporte de brazo (1) y una mesa auxiliar (2).In view of the figures outlined, and especially of figure 1, it can be seen how two complementary elements participate in the device of the invention, which are supplied forming a set of minimal volume, in which an arm support (1) and an auxiliary table (2) participate.

Pues bien, como se puede ver en los detalles de las figuras 6 a 7, el soporte de brazo (1) está constituido a partir de un base (3) laminar, esencialmente rectangular, destinada a insertarse bajo la colchoneta (4) del angiógrafo en correspondencia con el borde de la misma a la altura del brazo del paciente a estabilizar en la posición que se estime conveniente.Well, as can be seen in the details of figures 6 to 7, the arm support (1) is made up of a laminar base (3), essentially rectangular, designed to be inserted under the mattress (4) of the angiographer. in correspondence with its edge at the height of the patient's arm to be stabilized in the position deemed appropriate.

La base (3) se vincula a un elemento de asiento para el brazo, de configuración anatómica, aplanada, curvo cóncavo, en la que se define un tramo central (5) y mayoritariamente recto con sendos acodamientos extremos a la altura del codo (6) y mano del usuario (7), contando este último con una banda transversal (8) o bien disponiendo de una correa (8’) externa adaptable de forma análoga sobre la palma de la mano del usuario, tal como se representa en la figura 2.The base (3) is linked to a seat element for the arm, with an anatomical, flattened, concave curved configuration, in which a central section (5) is defined and mostly straight with two extreme bends at the height of the elbow (6). ) and the user's hand (7), the latter having a transverse band (8) or having an external strap (8') adaptable in a similar way on the palm of the user's hand, as shown in the figure two.

El soporte propiamente dicho se vincula a la base (3) a través de una articulación (9) con medios de bloqueo y desbloqueo a través de un mando (10) accesible inferiormente, a modo de embrague, que permite regular el grado de inclinación del soporte con respecto a la base de acuerdo a dos ejes de basculación, un eje de basculación horizontal, y un eje de basculación vertical.The support itself is linked to the base (3) through a joint (9) with locking and unlocking means through a control (10) accessible from below, like a clutch, which allows the degree of inclination of the support to be adjusted. support with respect to the base according to two tilting axes, a horizontal tilting axis, and a vertical tilting axis.

En la figura 8 se muestra una posible materialización de este mecanismo, si bien no se descarta cualquier otro mecanismo que permita este tipo de regulación con un único mando de accionamiento para todos los ajustes.Figure 8 shows a possible materialization of this mechanism, although any other mechanism that allows this type of regulation with a single actuation control for all adjustments is not ruled out.

En particular, en el ejemplo concreto de realización, la superficie que constituye el apoyo para el brazo se vincula a la articulación (9) a través de un eje de giro horizontal (11) con una rótula provista de un dentado (12) en el que es enclavable un elemento de bloqueo (13) desplazable radialmente a dicha rótula por medio del mando (10) rótula que a su vez puede girar con respecto de un imaginario eje vertical a través de un orificio (14) previsto en la base (3) a través de la que se hace pasar y que se bloquea igualmente a través del mando (10) por medio de una zapata (15) y con interposición de una junta de goma (16), de modo que el mando (10) acciona un tornillo que controla el desplazamiento relativo de la zapata (15) y el elemento de bloqueo (13) liberando o bloqueando ambos ejes de giro relativo.In particular, in the specific example of embodiment, the surface that constitutes the support for the arm is linked to the joint (9) through a horizontal axis of rotation (11) with a ball joint provided with a toothing (12) in the that a locking element (13) can be locked radially movable to said ball joint by means of the ball joint control (10), which in turn can rotate with respect to an imaginary vertical axis through a hole (14) provided in the base (3 ) through which it is passed and which is also blocked through the control (10) by means of a shoe (15) and with the interposition of a rubber gasket (16), so that the control (10) activates a screw that controls the relative displacement of the shoe (15) and the blocking element (13) releasing or blocking both axes of relative rotation.

No obstante, y como se decía, esta materialización es meramente ejemplaría, pudiendo el mando desplazarse verticalmente y solidario a un vástago en contra de la tensión de un resorte de modo que su desplazamiento vertical descendente, libera el elemento de bloqueo (13) y la zapata (15) en contra de la tensión de dicho muelle, o bien tratarse de cualquier tipo de rótula que incluya medios de regulación de este tipo.However, and as was said, this materialization is merely exemplary, the control being able to move vertically and integral with a stem against the tension of a spring so that its downward vertical displacement releases the blocking element (13) and the shoe (15) against the tension of said spring, or be any type of ball joint that includes adjustment means of this type.

En la figura 6 puede observarse como la base (13) incluye un orificio rasgado (17) que determina un asa de transporte manual para el soporte de brazo.In figure 6 it can be seen how the base (13) includes a slotted hole (17) that defines a manual carrying handle for the arm support.

De acuerdo con las figuras 9 y 10, la mesa auxiliar (2) está obtenida a partir de dos piezas laminares de perfil en "L” (18-19) que están parcialmente superpuestas entre sí formando un perfil en

cuya rama inferior define el medio de estabilización de la misma mediante inserción bajo la colchoneta del angiógrafo, mientras que la rama horizontal superior de la pieza complementaria define la superficie de apoyo auxiliar, incluyendo estas dos piezas medios de regulación posicional vertical relativa entre las mismas a partir de unos medios de guiado (20) y bloqueo en diferentes posiciones.According to figures 9 and 10, the auxiliary table (2) is obtained from two laminar pieces of "L" profile (18-19) that are partially superimposed on each other forming a profile in

whose lower branch defines the stabilization means thereof by inserting it under the angiographer's mat, while the upper horizontal branch of the complementary piece defines the auxiliary support surface, these two pieces including relative vertical positional adjustment means between them from guiding means (20) and blocking in different positions.

De forma más concreta, una de las ramas verticales de una de las piezas incluirá una pareja de ranuras verticales extremas (21) en la que juegan los medios de guiado (20), mientras que en la zona central dicha pieza incluirá una ranura central vertical (22) con sendos ensanchamientos (23) en correspondencia con sus extremidades y su zona media, en los que es enclavable selectivamente un tetón (24) desplazable axialmente por presionado de un pulsador (25) accesible desde la parte frontal de la mesa, en contra de la tensión de un resorte.More specifically, one of the vertical branches of one of the pieces will include a pair of extreme vertical slots (21) in which the guide means (20) play, while in the central area said piece will include a central vertical slot (22) with respective widenings (23) in correspondence with its extremities and its middle zone, in which a lug (24) movable axially by pressing a button (25) accessible from the front of the table, is selectively lockable, in against the tension of a spring.

Solo resta señalar por último que tanto el soporte del brazo como la mesa auxiliar estarán obtenidos en materiales radiológicamente compatibles, preferentemente material anti bacteriano. Finally, it only remains to point out that both the arm support and the auxiliary table will be made of radiologically compatible materials, preferably antibacterial material.
