Description

Canal de trabajo accesorio para broncoscopia y endoscopia digestiva.Accessory working channel for bronchoscopy and digestive endoscopy

Object of the invention

La presente invención se refiere a un canal de trabajo accesorio para ser utilizado en broncoscopia o endoscopia digestiva y con ello mejorar el estado de la técnica.The present invention relates to a channel of accessory work to be used in bronchoscopy or endoscopy digestive and thereby improve the state of the art.

El objeto de la invención es aportar un canal de trabajo adicional al ya existente en la endoscopia convencional mejorando el rendimiento diagnóstico y terapéutico asociado a la técnica.The object of the invention is to provide a channel of additional work to that already existing in conventional endoscopy improving diagnostic and therapeutic performance associated with technique.

Background of the invention

En la broncoscopia y endoscopia digestiva flexible existe un canal de trabajo interno dentro del endoscopio que permite la realización de técnicas diagnosticas y terapéuticas en el paciente al que se le realiza el procedimiento.In bronchoscopy and digestive endoscopy flexible there is an internal working channel inside the endoscope which allows the realization of diagnostic and therapeutic techniques in the patient to whom the procedure is performed.

Existen diferentes calibres de canales de trabajo en función del propósito de la técnica y del calibre del endoscopio.There are different channel sizes of work depending on the purpose of the technique and the caliber of the endoscope

También existen catéteres guía que se insertan en el interior del canal de trabajo de un endoscopio y a través de los cuales se introducen a su vez herramientas tales como sondas de ecografía radial permitiendo una mayor protección de dichas herramientas.There are also guide catheters that are inserted inside the working channel of an endoscope and through which in turn are introduced tools such as probes of radial ultrasound allowing greater protection of said tools

Description of the invention

El canal de trabajo accesorio que se preconiza consiste en un conjunto de dos catéteres con un sistema de fijación en su extremo distal. La pieza 1 presenta dos fenestraciones 3 al objeto de poder fijarse con la pieza 2 mediante un sistema de rieles semicirculares 4.The accessory work channel that is recommended It consists of a set of two catheters with a fixation system at its distal end. Piece 1 presents two fenestrations 3 to in order to be able to fix with part 2 by means of a rail system semicircular 4.

Es fundamental el hecho de que la pieza 1 no presente ningún elemento que sobresalga del calibre del propio catéter ya que va a ser introducido por el canal de trabajo interno del endoscopio saliendo al exterior por su extremo distal. La pieza 2 se dispone en el exterior del endoscopio, efectuándose la unión de ambas en el extremo distal de dichas piezas fuera del endoscopio.The fact that part 1 is not fundamental is essential present any element that stands out from its own caliber catheter as it will be introduced through the internal work channel of the endoscope going outside at its distal end. The piece 2 is arranged outside the endoscope, the union of both at the distal end of said pieces outside the endoscope

La pieza 2 presenta una estructura en el extremo distal que le permite ajustarse a la pared de la pieza 1 mediante dos rieles semicirculares 4 que presentan la forma inversa de las fenestraciones 3 y que impiden que se separen las piezas 1 y 2. Estos rieles se introducen en las fenestraciones por una zona de inserción 5 que es oblicua a la pared de la pieza 1.Piece 2 has a structure at the end distal that allows it to fit the wall of part 1 by two semicircular rails 4 that have the inverse form of the fenestrations 3 and that prevent parts 1 and 2 from being separated. These rails are introduced into fenestrations by an area of insert 5 which is oblique to the wall of part 1.

El sistema de rieles 4 presenta el mismo grosor que la pared de la pieza 1 y por tanto en ningún caso ocupará el calibre interno de la pieza 1, manteniendo así intacto el canal de trabajo interior.The rail system 4 has the same thickness that the wall of piece 1 and therefore in no case will occupy the internal caliber of part 1, thus keeping intact the channel of interior work

El extremo proximal 6 tanto de la pieza 1 y 2 presenta el orificio de entrada para las herramientas que se utilizaran en función de la técnica realizada.The proximal end 6 of both piece 1 and 2 presents the entrance hole for the tools that are will use depending on the technique performed.

Preferred Embodiment of the Invention

Como se puede ver en las figuras referidas el sistema se compone de dos piezas, acoplables entre sí. Siendo la pieza 1 fenestrada y sin resaltes que impidan su uso a través del canal de trabajo interno del endoscopio.As you can see in the referred figures the system consists of two pieces, attachable with each other. Being the piece 1 fenestrated and without protrusions that prevent its use through Internal working channel of the endoscope.

La fenestración 3 de la pieza 1 presentará en un extremo una zona de inserción 5 que preferentemente será oblicua a la pared de la pieza 1 para una fácil entrada de los rieles de la pieza 2.The fenestration 3 of piece 1 will present in a end an insertion zone 5 which will preferably be oblique to the wall of piece 1 for easy entry of the rails of the piece 2.

Tanto la pieza 1 como la 2 se elaborarán preferentemente en plástico duro o semiduro. Ambas piezas quedarán sujetas por el rozamiento de los materiales y pudiendo volver a desajustarlas en caso de que sea necesario.Both piece 1 and 2 will be made preferably in hard or semi-hard plastic. Both pieces will remain subject to the friction of the materials and may return to mismatch them if necessary.

Preferentemente ambas piezas serán de un solo uso.Preferably both pieces will be single use.
