Description

ORTESIS DE MU ECA  MU ECA ORTHESIS
CAMPO TECNICO DE LA INVENCION TECHNICAL FIELD OF THE INVENTION
La presente invención se engloba en el campo de los aparatos ortopédicos, particularmente, de las órtesis de muñeca empleadas para suprimir o mitigar el efecto de temblores patológicos. The present invention encompasses in the field of orthopedic devices, particularly wrist braces used to suppress or mitigate the effect of pathological tremors.
Dicha invención se basa fundamentalmente en el empleo de amortiguadores rotatorios o giratorios en paralelo con la articulación que se quiere controlar, es decir, entre la mano y el antebrazo. ANTECEDENTES DE LA INVENCIÓN Said invention is fundamentally based on the use of rotary or rotating dampers in parallel with the joint to be controlled, that is, between the hand and the forearm. BACKGROUND OF THE INVENTION
El temblor es una oscilación rítmica The tremor is a rhythmic swing
involuntaria de una parte del cuerpo. Aunque es normal tener una pequeña componente de temblor, existen involuntary of a body part. Although it is normal to have a small tremor component, there are
patologías con temblores muy discapacitantes. pathologies with very disabling tremors.
Los temblores patológicos son trastornos del movimiento muy frecuentes, y en muchos casos, son resistentes a los tratamientos habituales, es decir, farmacológicos o quirúrgicos. Pathological tremors are very frequent movement disorders, and in many cases, they are resistant to the usual treatments, that is, pharmacological or surgical.
Por tal razón, las órtesis constituyen una alternativa a dichos tratamientos habituales en los casos en que éstos no son eficaces o el propio paciente lo rechaza. For this reason, orthoses are an alternative to such usual treatments in cases where they are not effective or the patient himself refuses.
Actualmente son conocidos diversos sistemas ortopédicos para los miembros superiores que persiguen eliminar o al menos mitigar los efectos de los temblores patológicos. Por ejemplo, el documento de patente US 4842607, publicado el 27 de junio de 1989, describe que se reduce el temblor mediante un guante en el que se introduce la mano del paciente. Various orthopedic systems are currently known for the upper limbs that seek to eliminate or at least mitigate the effects of pathological tremors. For example, US 4842607, published June 27, 1989, describes that the tremor is reduced by a glove in which the patient's hand is introduced.
A dicho guante están acoplados dos transductores por medio de dos muelles. Estos transductores permiten provocar fuerzas opuestas al temblor, estabilizando asi la mano del paciente a tratar. Two transducers are coupled to said glove by means of two springs. These transducers allow to cause forces opposite to the tremor, thus stabilizing the patient's hand to be treated.
Este sistema tiene la desventaja que se logra reducir el temblor pero a costa de un gran gasto This system has the disadvantage that reduces tremor but at the expense of a large expense
energético para el paciente. Energetic for the patient.
Por su parte, el documento de patente US 6730049, publicado el 4 de mayo de 2004, muestra un dispositivo que consiste en una tablilla que alberga el antebrazo, la muñeca y la mano del paciente. For its part, US 6730049, published on May 4, 2004, shows a device consisting of a splint that houses the patient's forearm, wrist and hand.
En este caso, el temblor se reduce a través del empleo de un giroscopio que estabiliza la mano del paciente contrarrestando la fuerza provocada por el temb1or . In this case, the tremor is reduced through the use of a gyroscope that stabilizes the patient's hand by counteracting the force caused by the tremor.
Asi mismo, el documento de patente US 5337737, publicado el 16 de agosto de 1994, muestra una órtesis dividida en dos partes. La primera parte encierra el miembro superior hasta el codo y la segunda fija el antebrazo y llega hasta la mano. Likewise, patent document US 5337737, published on August 16, 1994, shows an orthosis divided into two parts. The first part encloses the upper limb to the elbow and the second part fixes the forearm and reaches the hand.
Ambas partes se encuentran unidad entre si por medio de un amortiguador lineal que permite que pivoteen uno con respecto al otro. Estas soluciones anteriores poseen la desventaja de ser aparatos complejos, de múltiples elementos dispuestos prácticamente en todo el brazo del paciente. Por tal razón, son pesados y poco estéticos. Both parts are unity with each other by means of a linear shock absorber that allows them to pivot with respect to each other. These previous solutions have the disadvantage of being complex, multi-element devices arranged practically throughout the patient's arm. For this reason, they are heavy and not very aesthetic.
Entonces, se requiere diseñar un dispositivo sencillo, ligero y que no afecte la apariencia estética del paciente. DESCRIPCIÓN DE LA INVENCIÓN Then, it is required to design a simple, lightweight device that does not affect the aesthetic appearance of the patient. DESCRIPTION OF THE INVENTION
A la vista de lo anteriormente enunciado, la presente invención se refiere a una órtesis de muñeca para control del movimiento de la mano. In view of the foregoing, the present invention relates to a wrist orthosis for control of hand movement.
El dispositivo comprende un soporte de mano, el cual puede ser fijado a la mano del usuario, es decir, un paciente aquejado de temblor patológico, y un soporte de antebrazo que puede ser fijado al antebrazo de dicho usuario. The device comprises a hand support, which can be fixed to the user's hand, that is, a patient suffering from pathological tremor, and a forearm support that can be fixed to the forearm of said user.
El soporte de mano y el soporte de antebrazo están unidos en una articulación giratoria que incluye un amortiguador rotatorio que controla el movimiento giratorio de dicha articulación. The hand support and forearm support are joined in a rotating joint that includes a rotary damper that controls the rotational movement of said joint.
El uso del amortiguador rotatorio permite tanto a la muñeca como el codo poder moverse en todo su rango articular en los ejes de flexión-extensión logrando, al mismo tiempo, reducir el temblor patológico. The use of the rotary damper allows both the wrist and the elbow to be able to move throughout their articular range in the flexion-extension axes, while reducing pathological tremor.
Por otro lado, el dispositivo propuesto es un dispositivo pasivo, es decir, logra contrarrestar los movimientos involuntarios producidos por el temblor sin el empleo de motores o actuadores electromecánicos. Asi mismo, su diseño es sencillo y estético con un mínimo de elementos, es decir, sin necesidad de gran número de elementos que cubran parte o la totalidad del brazo afectado, por ejemplo, grandes férulas con amortiguadores lineales dispuestos en su exterior. On the other hand, the proposed device is a passive device, that is, it manages to counteract the involuntary movements produced by the tremor without the use of electromechanical motors or actuators. Likewise, its design is simple and aesthetic with a minimum of elements, that is, without the need for a large number of elements that cover part or all of the affected arm, for example, large splints with linear dampers arranged outside.
Por tanto, se logra un dispositivo eficaz, ligero y discreto. Valores muy apreciados por usuarios que sufren estos temblores patológicos. Therefore, an efficient, lightweight and discreet device is achieved. Values highly appreciated by users who suffer from these pathological tremors.
