Description

Campo de la invención Field of the Invention

La presente invención se refiere a un catéter para drenaje del líquido de secreción pancreática, especialmente concebido para ser utilizado en cirugía pancreática. The present invention relates to a catheter for drainage of pancreatic secretion fluid, especially designed to be used in pancreatic surgery.

Estado de la técnica State of the art

En la cirugía de resección pancreática, después de la extirpación de la cabeza del páncreas, o duodenopancreatectomía, se debe realizar la reconstrucción del tránsito digestivo mediante una serie de anastomosis. La más delicada de ellas es la que se lleva a cabo entre el conducto pancreático, una vez seccionado el páncreas, y la luz de un asa In pancreatic resection surgery, after the removal of the head of the pancreas, or duodenopancreatectomy, the reconstruction of the digestive transit must be performed through a series of anastomosis. The most delicate of these is that which is carried out between the pancreatic duct, once the pancreas is sectioned, and the light of a handle

o segmento de intestino delgado, ya que el conducto pancreático es de un calibre muy pequeño (menor de 3mm en condiciones normales), y el tejido pancreático que lo rodea es muy friable, lo que motiva que sea difícil aplicar en él puntos de sutura resistentes a la tracción. or segment of the small intestine, since the pancreatic duct is of a very small caliber (less than 3mm in normal conditions), and the surrounding pancreatic tissue is very friable, which makes it difficult to apply resistant stitches on it to traction

Hasta ahora, en las anastomosis pancreáticas se han utilizado tubos finos de polivinilo para tutorizar dichas anastomosis, y así evitar su colapso y con ello la aparición de fístulas pancreáticas que implican el paso de líquido de secreción pancreática a la cavidad abdominal y la aparición de complicaciones potencialmente graves. La eficacia de estos tubos tutores ha sido hasta la actualidad relativa y cuestionada, debido al riesgo de desplazamientos longitudinales indeseados y de la obliteración o colapso de dichos tubos, generalmente a causa de compresiones extrínsecas al ser exteriorizados a través de la pared intestinal y a través de la pared abdominal. Until now, thin polyvinyl tubes have been used in the pancreatic anastomoses to tutor these anastomoses, and thus prevent their collapse and thus the appearance of pancreatic fistulas that involve the passage of pancreatic secretion fluid into the abdominal cavity and the appearance of complications potentially serious. The efficacy of these guardian tubes has been up to now relative and questioned, due to the risk of unwanted longitudinal displacements and the obliteration or collapse of said tubes, generally due to extrinsic compressions when exteriorized through the intestinal wall and through abdominal wall

Descripción de la invención Description of the invention

La presente invención tiene por objeto un catéter para cirugía pancreática, que permite tutorizar la anastomosis del conducto pancreático con el asa o segmento del intestino de un modo seguro y eficaz. The present invention aims at a catheter for pancreatic surgery, which allows the anastomosis of the pancreatic duct to be tutored with the handle or segment of the intestine in a safe and effective way.

Otro objeto de la invención es desarrollar un catéter que permita, mediante su conexión a un sistema de vacío “a baja presión”, llevar a cabo la extracción de toda la secreción del páncreas, evitando de esta forma la aparición de fístulas pancreáticas. Another object of the invention is to develop a catheter that allows, through its connection to a "low pressure" vacuum system, to carry out the extraction of all the secretion of the pancreas, thus avoiding the appearance of pancreatic fistulas.

El catéter es de estructura tubular, de naturaleza flexible y de gran longitud respecto de su sección, y comprende dos tramos de diferente resistencia y sección, un primer tramo de reducido calibre, preferentemente con un diámetro menor de 3mm., y un segundo tramo de mayor calibre, con pared reforzada, de modo que sea más resistente al aplastamiento. The catheter is of tubular structure, of a flexible nature and of great length with respect to its section, and comprises two sections of different strength and section, a first section of reduced caliber, preferably with a diameter of less than 3mm., And a second section of larger caliber, with reinforced wall, so that it is more resistant to crushing.

El primer tramo está destinado a poder introducirse a través de los conductos pancreáticos, de pequeño calibre, y está dotado en su pared de orificios a través de los que se llevará a cabo la succión del líquido de secreción pancreática, al conectar el catéter a una fuente de vacío. The first section is intended to be able to be introduced through the small-caliber pancreatic ducts, and it is provided in its wall with holes through which the suction of the pancreatic secretion fluid will be carried out, by connecting the catheter to a vacuum source.

El primer tramo presenta además un pequeño resalte externo, de superficies curvas, que sirve como medio para la fijación del catéter en la “boca” del conducto pancreático en el que está introducido el catéter, impidiendo su desplazamiento longitudinal accidental. The first section also has a small external projection, with curved surfaces, which serves as a means for fixing the catheter in the "mouth" of the pancreatic duct in which the catheter is inserted, preventing its accidental longitudinal displacement.

Por su parte, el segundo tramo está destinado a ser introducido a través de la pared del segmento del intestino y de la pared abdominal, al ser exteriorizado, debiendo permitir estos pasos sin que sufra aplastamientos o deformaciones pronunciadas que pudieran provocar el colapso del catéter. Para ello este segundo tramo es de mayor sección que el primer tramo y tiene su pared reforzada, por ejemplo mediante un mayor grosor de pared For its part, the second section is intended to be introduced through the wall of the segment of the intestine and the abdominal wall, to be exteriorized, and must allow these steps without suffering crushing or pronounced deformations that could cause the catheter to collapse. For this, this second section is of greater section than the first section and has its reinforced wall, for example by a greater wall thickness

o mediante aplicación de una camisa o segunda pared externa. or by applying a shirt or second external wall.

El segundo tramo queda rematado en su extremo libre en una boquilla, por ejemplo de tipo estándar, para su conexión a una fuente de vacío. The second section is topped at its free end in a nozzle, for example of standard type, for connection to a vacuum source.

5 Descripción detallada de un modo de realización 5 Detailed description of one embodiment

En la figura 1 se muestra un catéter de estructura tubular y naturaleza flexible, que comprende dos tramos de diferentes características: un primer tramo (1) de menor calibre, longitud y resistencia a la flexión, y un segundo tramo (2) de mayor diámetro, longitud y Figure 1 shows a catheter of tubular structure and flexible nature, comprising two sections of different characteristics: a first section (1) of smaller caliber, length and flexural strength, and a second section (2) of greater diameter , length and

10 resistencia, tanto a la flexión como al aplastamiento. 10 resistance, both to bending and crushing.

El tramo (1) está destinado a introducirse en los conductos pancreáticos, de pequeño calibre, por lo que tendrá un diámetro menor de 3mm. Además este primer tramo (1) dispone en su pared, tal y como puede apreciarse mejor en las figuras 2 y 3, de orificios The section (1) is intended to be introduced into the pancreatic ducts, small caliber, so it will have a diameter of less than 3mm. In addition, this first section (1) has holes in its wall, as can be best seen in Figures 2 and 3.

15 pasantes (3) a través de los que podrá pasar el líquido de secreción pancreática. 15 interns (3) through which the pancreatic secretion fluid may pass.

El tramo (1) dispone además de un pequeño resalte (4) de superficies curvas, que servirá como medio de sujeción de este tramo dentro del conducto pancreático en el que se introduce. The section (1) also has a small projection (4) of curved surfaces, which will serve as a means of securing this section within the pancreatic duct into which it is inserted.

20 En cuanto al tramo (2), es de mayor longitud y diámetro que el tramo (1), suficiente para atravesar la pared intestinal y la pared abdominal y sobresalir al exterior a través de su extremo libre, en el que lleva fijada una boquilla, preferentemente de tipo estándar, para su conexión a una fuente de vacío. 20 As for the section (2), it is of greater length and diameter than the section (1), sufficient to cross the intestinal wall and the abdominal wall and protrude to the outside through its free end, in which a nozzle is fixed , preferably of standard type, for connection to a vacuum source.

25 El tramo (2) tiene su pared reforzada, por ejemplo mediante un aumento de su grosor, de modo que ofrezca suficiente resistencia para evitar su aplastamiento durante el montaje a través de la pared del intestino y pared abdominal, lo cual provocaría el colapso del catéter. The section (2) has its reinforced wall, for example by an increase in its thickness, so as to offer sufficient resistance to prevent its crushing during assembly through the wall of the intestine and abdominal wall, which would cause the collapse of the catheter.

30 También la pared de este segundo tramo (2) podría estar constituida por una prolongación de la pared del tramo (1), con igual grosor, e ir dotada a lo largo de todo este tramo (2) de una camisa externa de refuerzo. 30 Also the wall of this second section (2) could be constituted by an extension of the wall of the section (1), with equal thickness, and be provided along all this section (2) of an external reinforcing jacket.

Gracias a las características del primer tramo (1), el catéter descrito permite tutorizar con garantías la anastomosis del conducto pancreático con el asa o segmento de intestino. Y gracias a las características del segundo tramo (2), el catéter puede ser extraído sin riesgo de colapso, a través de la pared del intestino y de la pared abdominal. Así se puede llevar a cabo la extracción de toda la secreción del páncreas a través de los orificios (3), al conectar la boquilla (5) a una fuente de vacío. Thanks to the characteristics of the first section (1), the described catheter allows to safely guard the anastomosis of the pancreatic duct with the loop or segment of intestine. And thanks to the characteristics of the second section (2), the catheter can be removed without risk of collapse, through the wall of the intestine and the abdominal wall. Thus, the entire secretion of the pancreas can be carried out through the holes (3), by connecting the nozzle (5) to a vacuum source.
