Description
Prótesis quirúrgica para el tratamiento de hernias inguinales. Surgical prosthesis for the treatment of inguinal hernias.
La presente invención define una prótesis para el tratamiento quirúrgico de hernias inguinales, constituida por una sola pieza plana, dividida en dos partes asimétricas que permiten un movimiento helicoidal una sobre la otra, y que una vez la prótesis está puesta en su posición genera diferentes áreas de refuerzo y resistencia, protege las zonas sensibles y débiles de las paredes abdominales y mejora el tratamiento de las hernias inguinales más comunes. The present invention defines a prosthesis for the surgical treatment of inguinal hernias, constituted by a single flat piece, divided into two asymmetric parts that allow a helical movement one over the other, and that once the prosthesis is put in its position generates different areas of reinforcement and resistance, it protects the sensitive and weak areas of the abdominal walls and improves the treatment of the most common inguinal hernias.
El uso de prótesis para resolver los problemas derivados de este tipo de hernias es conocido dentro del campo de la medicina. Estas prótesis están fabricadas de diferentes materiales, generalmente de materiales como el polipropileno, y ofrecen diversos diseños que resuelven ciertos problemas, pero sin alcanzar el grado de eficiencia obtenido con el presente invento. Destacamos ciertos registros como la patente EP01931800.5 de Cousin Biotech que desarrolla una prótesis para la reparación de hernias en forma troncocónica hueca con un extremo prominente cerrado, y que como se verá a continuación tiene un diseño y prestaciones totalmente diferentes al de la presente invención; en el caso de la patente EP00901329.3 de Sofradim Production se desarrolla una prótesis multicapa también para la corrección quirúrgica de los problemas derivados de las hernias inguinales, pero que se diferencia de la presente invención en que está constituida por dos elementos que se acoplan uno al otro. Pues bien, la presente invención se diferencia de las antecedentes en que está formada por un solo elemento plano, mejorando y simplificando las soluciones planteadas y existentes hasta la fecha. The use of prostheses to solve the problems derived from this type of hernias is known within the medical field. These prostheses are made of different materials, generally of materials such as polypropylene, and offer various designs that solve certain problems, but without reaching the degree of efficiency obtained with the present invention. We highlight certain records such as patent EP01931800.5 of Cousin Biotech that develops a prosthesis for the repair of herniations in a hollow truncated conical shape with a prominent closed end, and which as will be seen below has a totally different design and performance to that of the present invention ; In the case of the patent EP00901329.3 of Sofradim Production a multilayer prosthesis is also developed for the surgical correction of the problems derived from inguinal hernias, but which differs from the present invention in that it is constituted by two elements that are coupled one the other. Well, the present invention differs from the background in that it is formed by a single flat element, improving and simplifying the solutions proposed and existing to date.
En este sentido, cabe destacar el registro ES1057646U del mismo solicitante del presente invento, que se define como el registro más cercano en el estado de la técnica, que si bien plantea una prótesis formada por un solo elemento y plano con una pequeña cavidad, la nueva invención define una abertura u orificio central reforzado que mejora la pequeña cavidad anteriormente citada, además de tener en cuenta que con el presente diseño el acoplamiento a las paredes abdominales es más efectivo sujetando los movimientos de los músculos, y por otro lado el orificio central permite el paso del cordón espermático con una sujeción mejorada y sin el riesgo de estar sometido a ciertas presiones o estrangulamiento generado por la pequeña cavidad del anterior registro. Es por tanto que el presento invento mejora y se diferencia de los dispositivos existentes para el tratamiento quirúrgico de los problemas más frecuentes que aparecen en las hernias inguinales, en particular los dos tipos de hernias más comunes, mejorando y facilitando a su vez los procesos de rehabilitación de los pacientes. In this regard, it is worth noting the ES1057646U register of the same applicant of the present invention, which is defined as the closest register in the state of the art, which although it poses a prosthesis formed by a single flat element with a small cavity, the The new invention defines a reinforced central opening or hole that improves the small cavity mentioned above, in addition to taking into account that with the present design the coupling to the abdominal walls is more effective by holding the movements of the muscles, and on the other hand the central hole It allows the passage of the spermatic cord with an improved support and without the risk of being subjected to certain pressures or strangulation generated by the small cavity of the previous register. It is therefore that the present invention improves and differs from the existing devices for the surgical treatment of the most frequent problems that appear in inguinal hernias, in particular the two most common types of hernias, improving and facilitating in turn the processes of patient rehabilitation.
Definimos la presente prótesis quirúrgica, destinada preferentemente al tratamiento de hernias inguinales y en concreto para los dos tipos de hernias de este tipo más comunes, siendo colocada en el paciente internamente, como una prótesis formada por una sola pieza plana, dividida en dos secciones asimétricas, que al ser manipulada mediante un movimiento helicoidal o de plegado de una parte sobre la otra, genera una abertura central y permite que haya dos zonas de doble resistencia y refuerzo. La manipulación de dicha prótesis consiste en plegar o doblar una sección sobre la otra, de tal manera que la abertura central queda protegida con una doble resistencia formada por la superposición de ambas secciones asimétricas. We define the present surgical prosthesis, preferably intended for the treatment of inguinal hernias and specifically for the two most common types of hernias, being placed in the patient internally, as a prosthesis formed by a single flat piece, divided into two asymmetric sections , which when manipulated by a helical or folding movement of one part over the other, generates a central opening and allows two zones of double resistance and reinforcement. The manipulation of said prosthesis consists in folding or folding one section over the other, so that the central opening is protected with a double resistance formed by the superposition of both asymmetric sections.
Como se ha adelantado, la prótesis que es una pieza plana, que cuando está desplegada está formada por dos secciones o partes asimétricas respecto de una línea divisoria de corte central. La línea divisoria no corta toda la superficie de la prótesis, habiendo una zona cerrada o de continuidad que permite la unión de ambas partes asimétricas, y en la que en su extremo inicial hay una doblez que permite poder plegar ambas secciones asimétricas. Cada sección asimétrica está formada por un cuerpo semioval al que se le realiza en su extremo inferior una muesca o hendidura, de forma ovalada o circular, de la que parte una aleta inferior ovalada y oblonga. As anticipated, the prosthesis is a flat piece, which when deployed is formed by two sections or asymmetric parts with respect to a central cutting dividing line. The dividing line does not cut the entire surface of the prosthesis, having a closed or continuity zone that allows the union of both asymmetric parts, and in which at its initial end there is a fold that allows both asymmetric sections to be folded. Each asymmetric section is formed by a semi-oval body which is made at its lower end a notch or groove, oval or circular, from which an oval and oblong lower fin starts.
Una vez que ambas secciones asimétricas se pliegan una sobre la otra respecto de la línea divisoria de corte, el contorno exterior de la prótesis estará constituido por formas redondeadas, en las que no hay esquinas y/o aristas, de tal manera que el acoplamiento con las paredes internas es más ergonómico y menos agresivo. Además, se formará una abertura central formada por la superposición de las muescas o hendiduras de ambas secciones asimétricas. Dicha abertura u orificio central permite el paso del cordón espermático, y tiene una forma circular u ovalada que no tiene aristas o esquinas que permite que dicho cordón espermático no sufra problemas de presión o estrangulamiento. Como también se ha adelantado, el plegado de ambas secciones asimétricas genera dos zonas de doble refuerzo o resistencia, lo cual supone un gran adelanto dado generalmente para generar un una doble resistencia era necesario utilizar dos prótesis superpuestas, además, con estas dos zonas de mayor resistencia se da solución a los dos tipos más frecuentes de hernias inguinales. Once both asymmetric sections fold over each other with respect to the dividing line of cut, the outer contour of the prosthesis will consist of rounded shapes, in which there are no corners and / or edges, so that the coupling with The internal walls are more ergonomic and less aggressive. In addition, a central opening will be formed formed by the superposition of the notches or indentations of both asymmetric sections. Said opening or central hole allows the passage of the spermatic cord, and has a circular or oval shape that has no edges or corners that allows said spermatic cord to not suffer from pressure or strangulation problems. As has also been advanced, the folding of both asymmetric sections generates two zones of double reinforcement or resistance, which is a great advance given generally to generate a double resistance it was necessary to use two superimposed prostheses, in addition, with these two areas of greater Resistance is given to the two most frequent types of inguinal hernias.
Para completar la descripción que se está realizando y con objeto de ayudar a una mejor comprensión de las características del invento, se acompaña como parte integrante de la misma un juego de dibujos en donde con carácter ilustrativo y no limitativo se ha representado lo siguiente: In order to complete the description that is being made and in order to help a better understanding of the characteristics of the invention, a set of drawings is attached as an integral part thereof, where the following has been represented as an illustrative and non-limiting nature:

Descripción de los dibujos Description of the drawings
Como se observa en la Fig.1, una representación de una vista frontal de la prótesis desplegada define una prótesis que es una pieza plana formada por dos secciones o partes asimétricas (1 y 1’) respecto de una línea divisoria (2) de corte central. La línea divisoria no corta toda la superficie de la prótesis, habiendo una zona cerrada o de continuidad As seen in Fig. 1, a representation of a front view of the deployed prosthesis defines a prosthesis that is a flat piece formed by two sections or asymmetric parts (1 and 1 ') with respect to a dividing line (2) of cut central. The dividing line does not cut the entire surface of the prosthesis, having a closed or continuity zone
(3) que permite la unión de ambas partes asimétricas, y en la que en su extremo inicial hay una doblez (4) que permite el plegar ambas secciones simétricas. Cada sección asimétrica (1 y 1´) está formada por un cuerpo semioval (11 y 11´) al que se le realiza en su extremo inferior una muesca (12 y 12´) o hendidura, de forma ovalada o circular, de la que parte una aleta inferior ovalada y oblonga (13 y 13´). (3) that allows the union of both asymmetric parts, and in which at its initial end there is a fold (4) that allows folding both symmetrical sections. Each asymmetric section (1 and 1´) is formed by a semi-oval body (11 and 11´) to which a notch (12 and 12´) is made at its lower end or a groove, oval or circular, from which part of an inferior oval and oblong fin (13 and 13´).
Como se observa en las Fig.2 la prótesis está plegada cuando ambas secciones asimétricas (1 y 1´) se pliegan o doblan una sobre la otra respecto de la línea divisoria de corte mediante un movimiento helicoidal. Además, se formará una abertura central (120) formada por la superposición de las muescas o hendiduras (12 y 12´) de ambas secciones asimétricas. Cuando la prótesis está plegada, hay dos zonas principales en las que hay una doble resistencia, la cual pertenece a la superposición de ambas secciones asimétricas, de manera que ambos refuerzos o zonas de doble resistencia a su vez protegen la abertura central (120). En este sentido, se puede definir que hay una zona de mayor resistencia superior (110) generada por la superposición de ambas superficies semiovales (11 y 11´) y una zona de mayor resistencia inferior (130) generada por la superposición de ambas aletas inferiores ovaladas y oblongas (13 y 13´). El que ambas secciones sean asimétricas favorecen el movimiento helicoidal, en el caso de las figuras se puede observar como hay una leve asimetría entre ambas superficies semiovales (11 y 11´) y ambas aletas (13 y 13´). As can be seen in Fig. 2, the prosthesis is folded when both asymmetric sections (1 and 1 ') fold or fold over each other with respect to the dividing line of cut by means of a helical movement. In addition, a central opening (120) formed by the superposition of the notches or grooves (12 and 12 ') of both asymmetric sections will be formed. When the prosthesis is folded, there are two main areas in which there is a double resistance, which belongs to the superposition of both asymmetric sections, so that both reinforcements or zones of double resistance in turn protect the central opening (120). In this sense, it can be defined that there is a zone of greater upper resistance (110) generated by the superposition of both semioval surfaces (11 and 11 ') and an area of greater lower resistance (130) generated by the superposition of both lower fins oval and oblong (13 and 13´). The fact that both sections are asymmetrical favors the helical movement, in the case of the figures it can be observed how there is a slight asymmetry between both semioval surfaces (11 and 11´) and both fins (13 and 13´).
Como se observa en la Fig.3, dicha abertura (120) u orificio central permite el paso del cordón espermático, y tiene una forma circular u ovalada que no tiene aristas o esquinas permite que el cordón espermático (5) no sufra problemas de presión o estrangulamiento, quedando a su vez sujeto y fijado. Además, siguiendo con lo explicado en la figura anterior, se aprovecha para representar también las zonas de doble resistencia (110 y 130). As seen in Fig. 3, said opening (120) or central hole allows the passage of the spermatic cord, and has a circular or oval shape that has no edges or corners allows the spermatic cord (5) to not suffer pressure problems or strangulation, being in turn subject and fixed. In addition, following what has been explained in the previous figure, it is used to also represent the double resistance zones (110 and 130).
El plegado de ambas caras se genera por un movimiento helicoidal y se puede hacer el plegado tanto el de la sección izquierda sobre la derecha tal como se representa en la Fig.4, o como el de la sección derecha sobre la izquierda tal como se representa en la Fig.5. Como se puede observar de las Fig.2 a la Fig,.5, el contorno exterior de la prótesis una vez está plegada, estará constituidas por contornos o formas redondeadas, en las que no hay esquinas y/o aristas, de tal manera que el acoplamiento con las paredes internas es más ergonómico y menos agresivo. The folding of both faces is generated by a helical movement and the folding of both the left section on the right can be done as shown in Fig. 4, or as the one on the right section on the left as represented in Fig. 5. As can be seen from Fig. 2 to Fig. .5, the outer contour of the prosthesis once folded, will be constituted by contours or rounded shapes, in which there are no corners and / or edges, such that The coupling with the internal walls is more ergonomic and less aggressive.
