DISPOSITIVO QUIRÚRGICO DE EXTRACCIÓN DE PIEZAS QUIRÚRGICAS  SURGICAL EXTRACTION DEVICE FOR SURGICAL PARTS
OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION
La presente invención pertenece al sector del equipamiento médico quirúrgico y más concretamente al de las bolsas de extracción de piezas quirúrgicas. El objeto principal de la presente invención es un dispositivo de extracción de piezas quirúrgicas previsto para aislar, contener y extraer tejido corporal del interior del cuerpo, como parte de un procedimiento quirúrgico mínimamente invasivo, de forma que optimiza el proceso reduciendo el volumen de las piezas quirúrgicas, aumentando su consistencia y moldeándolas con una forma alargada mediante un mecanismo de insuflado, y en general también posterior extracción del fluido gas o líquido, aplicado a unas correspondientes sub-cámaras de una cámara intermedia de una bolsa de doble capa contenedora de la pieza quirúrgica. ANTECEDENTES DE LA INVENCIÓN  The present invention belongs to the sector of surgical medical equipment and more specifically to the bags for extracting surgical pieces. The main object of the present invention is a device for extracting surgical pieces intended to isolate, contain and remove body tissue from inside the body, as part of a minimally invasive surgical procedure, so that it optimizes the process by reducing the volume of the pieces Surgical, increasing their consistency and shaping them with an elongated shape by means of an insufflation mechanism, and in general also subsequent extraction of the gas or liquid fluid, applied to corresponding sub-chambers of an intermediate chamber of a double layer bag containing the piece surgical BACKGROUND OF THE INVENTION
Los procedimientos quirúrgicos laparoscópicos y endoscópicos son procedimientos mínimamente invasivos en los que se realizan operaciones dentro del cuerpo por medio de instrumentos alargados insertados a través de estrechas aberturas de entrada practicadas en el cuerpo. La abertura inicial en el tejido corporal para permitir el paso de los instrumentos endoscópicos o laparoscópicos hasta el interior del cuerpo puede ser un pasaje natural del cuerpo, o puede crearse por medio de un instrumento perforador de tejido tal como un trocar. Los procedimientos laparoscópicos y endoscópicos requieren en general que se sellen cualquier instrumentación insertada en el cuerpo, es decir que han de tomarse medidas para asegurar que no entren ni salgan gases del cuerpo a través del instrumento de la incisión de entrada de modo que pueda insuflarse la región quirúrgica del cuerpo, por ejemplo, la cavidad abdominal.  Laparoscopic and endoscopic surgical procedures are minimally invasive procedures in which operations are performed inside the body by means of elongated instruments inserted through narrow entry openings made in the body. The initial opening in the body tissue to allow the passage of endoscopic or laparoscopic instruments into the body can be a natural passage of the body, or it can be created by means of a tissue piercing instrument such as a trocar. Laparoscopic and endoscopic procedures generally require that any instrumentation inserted in the body be sealed, that is, measures must be taken to ensure that no gases enter or leave the body through the instrument of the entry incision so that the insufflation can be insufflated. surgical region of the body, for example, the abdominal cavity.
La actuación mecánica de tales instrumentos está en su mayor parte limitada al movimiento de los diversos componentes a lo largo de un je longitudinal con medios previstos para convertir el movimiento longitudinal en un movimiento lateral cuando sea necesario. Como los tubos endoscópicos o laparoscópicos, la instrumentación y cualesquiera punciones o incisiones requeridas son elativamente estrechos, la cirugía endoscópica o laparoscópica es menos invasiva y produce mucho menos trauma en el paciente en comparación con procedimientos en los que se requiere que el cirujano realice grandes incisiones.  The mechanical performance of such instruments is mostly limited to the movement of the various components along a longitudinal je with means provided to convert the longitudinal movement into a lateral movement when necessary. As endoscopic or laparoscopic tubes, instrumentation and any punctures or incisions required are elastically narrow, endoscopic or laparoscopic surgery is less invasive and produces much less trauma in the patient compared to procedures in which the surgeon is required to make large incisions. .
Los procedimientos mínimamente invasivos se utilizan a menudo para extraer total o parcialmente tejido corporal u órganos del interior del cuerpo. Durante tales  Minimally invasive procedures are often used to totally or partially remove body tissue or organs from inside the body. During such
C0NFIRMATI0N C0PY procedimientos, es corriente que un tejido u órgano afectado tenga que ser extraído por la abertura de acceso practicada en la piel o a través de una cánula. A fin de evitar contaminación infecciosa o diseminación oncológica, es necesario aislar la pieza quirúrgica de la pared abdominal, torácica etc. a la hora de la extracción. Para tal fin son utilizados elementos de extracción que aislan la pieza e impiden el contacto con el resto de tejidos en su trayectoria de salida. C0NFIRMATI0N C0PY procedures, it is common for an affected tissue or organ to have to be removed through the access opening made in the skin or through a cannula. In order to avoid infectious contamination or oncological dissemination, it is necessary to isolate the surgical part from the abdominal, thoracic wall etc. at the time of extraction. To this end, extraction elements are used that isolate the piece and prevent contact with the rest of the tissues in its exit path.
Se han descrito diversos tipos de dispositivos de retirada de muestras para facilitar este procedimiento como, por ejemplo, los sistemas comerciales Endo Catch® y Endobag® Autosuture, US Surgical, Inc.  Various types of sample collection devices have been described to facilitate this procedure, such as the commercial systems Endo Catch® and Endobag® Autosuture, US Surgical, Inc.
Dentro de este ámbito, es conocida la utilización de aparatos de succión, para aplicar el vacío, como, por ejemplo, la solicitud de patente US 2006/0200169 A1 Sniffin 2006.  Within this scope, the use of suction apparatus is known to apply the vacuum, such as, for example, the patent application US 2006/0200169 A1 Sniffin 2006.
Por otro lado, en la patente ES 2 129 464 T3 se divulga una bolsa que tiene por lo menos dos capas para formar unos canales de fluidos distribuidos sobre la superficie de dicha bolsa que utiliza un aparato de insuflación como medio para proveer un fluido a los canales de fluidos de la bolsa del aislamiento de forma que la fuerza de estos canales la bolsa del aislamiento permitan la apertura en una orientación preferida.  On the other hand, ES 2 129 464 T3 discloses a bag having at least two layers to form fluid channels distributed on the surface of said bag that uses an insufflation apparatus as a means to provide a fluid to the fluid channels of the insulation bag so that the force of these channels the insulation bag allows opening in a preferred orientation.

No se enseña ni se sugiere en ES 2 129464 T3 ninguna configuración que permite realizar, mediante el inflado de la cámara intermedia de la bolsa, otra función diferente a la indicada de despliegue de la bolsa. Dicha otra función tampoco es indicada en dicha patente. It is not taught or suggested in ES 2 129464 T3 any configuration that allows to perform, by inflating the intermediate chamber of the bag, another function different from the indicated deployment of the bag. Said other function is also not indicated in said patent.
A pesar de estos avances sigue existiendo la necesidad de un dispositivo de recuperación de muestras mejorado que ayude a compactar y moldear la muestra para facilitar la extracción y evite grandes incisiones.  Despite these advances, there is still a need for an improved sample recovery device that helps compact and mold the sample to facilitate extraction and avoid large incisions.

A continuación se describe el funcionamiento del objeto de la invención aplicado a esta realización preferente, el cual viene descrito en la secuencia de las Figs. 5a a 5d: The operation of the object of the invention applied to this preferred embodiment is described below, which is described in the sequence of Figs. 5th to 5th:
• El dispositivo quirúrgico 1 contiene en su interior los medios de adaptación 9, que estarán inicialmente en posición plegada y retraída, que envuelven en su interior la bolsa 5 enrollada en el soporte de bolsa 3, teniendo la banda extensible y cerrada en posición plegada. Los medios de insuflación y succión también estarán retraídos y todo podrá moverse entre una posición proximal, al menos parcialmente dentro del elemento tubular 2 y una posición distal al menos parcialmente exterior al elemento tubular 2. • The surgical device 1 contains in its interior the adaptation means 9, which will initially be in a folded and retracted position, which wrap inside the bag 5 wound in the bag holder 3, the extendable and closed band being in the folded position. The insufflation and suction means will also be retracted and everything can move between a proximal position, at least partially within the tubular element 2 and a distal position at least partially outside the tubular element 2.
· Despliegue del dispositivo quirúrgico 1. Cuando se hace avanzar el elemento de accionamiento 10 saldrán del extremo distal del elemento tubular 2 los medios de adaptación 9, que paulatinamente van desplegándose, dejando al descubierto el soporte de bolsa 3 y la bolsa 5, y los medios de insuflación y succión. Al desplegarse los medios de adaptación 9, el soporte de bolsa 3 y la bolsa 5, pasan a la posición desplegada con la acción de la banda extensible y cerrada facilitando la apertura de 20 la bolsa 5, desplegando asimismo el tubo de succión 7 y el tubo de insuflación y succión 8 en el interior de la bolsa 5 y en el interior de la cámara intermedia 15 respectivamente.· Deployment of the surgical device 1. When the drive element 10 is advanced, the means of displacement of the tubular element 2 will exit adaptation 9, which gradually unfolds, exposing the bag holder 3 and the bag 5, and the insufflation and suction means. When the adaptation means 9, the bag holder 3 and the bag 5 are deployed, they move into the deployed position with the action of the extensible and closed band facilitating the opening of the bag 5, also displaying the suction tube 7 and the insufflation and suction tube 8 inside the bag 5 and inside the intermediate chamber 15 respectively.
• Inserción de la muestra quirúrgica en la bolsa 5. • Insertion of the surgical sample into the bag 5.
• Cierre de la bolsa 5. Para ello, se estira de la cuerda de tracción 6 hasta un primer punto en el cual horca el nudo 15 corredizo, que aparece en la Fig. 4, cerrando la bolsa 5 y separando completamente la bolsa 5 del soporte de bolsa 3, de forma que el soporte e bolsa 3 comienza a retraerse y la bolsa 5, ya separada, se cierra aunque teniendo aún los medios de insuflación y succión ubicados en su interior.  • Closing the bag 5. To do this, pull the pull rope 6 to a first point where the sliding knot 15, which appears in Fig. 4, hangs, closing the bag 5 and completely separating the bag 5 from the bag holder 3, so that the bag holder 3 begins to retract and the bag 5, already separated, closes although still having the insufflation and suction means located inside.
• Compactación y moldeo de la muestra quirúrgica. Para ello se insufla fluido en el interior de la cámara intermedia 15 a través del tubo de insuflación 8, de forma que comprime el interior de a bolsa 5 a una forma alargada, propiciando la expulsión de los líquidos y gases de la muestra. Adicionalmente, se aplica el vacío en el interior de la bolsa 5 a través de los múltiples orificios de vacío del tubo de succión 7, y finalmente, también se retira el fluido de la cámara intermedia 14 a través del tubo de succión 8. • Compaction and molding of the surgical sample. For this, fluid is blown into the interior of the intermediate chamber 15 through the insufflation tube 8, so that it compresses the inside of the bag 5 to an elongated shape, leading to the expulsion of liquids and gases from the sample. Additionally, the vacuum is applied inside the bag 5 through the multiple vacuum holes of the suction tube 7, and finally, the fluid is also removed from the intermediate chamber 14 through the suction tube 8.
• Repliegue del dispositivo quirúrgico 1. Para ello se estira de la cuerda de tracción 6 hasta un segundo punto, en el cual el soporte de bolsa 3 y los medios de insuflación y succión están completamente retraídos y ubicados en la posición proximal al menos parcialmente dentro del conducto del elemento tubular 2. Por otro lado, la bolsa 5 con la muestra, compactadas y moldeadas a la forma alargada, se acopla a los medios de adaptación 9 de la pared abdominal de forma que ambas están dispuestas una seguida de la otra, presentando una continuidad en la forma de la bolsa 5, respecto del medio de adaptación 9. • Folding of the surgical device 1. To this end, the pull rope 6 is stretched to a second point, in which the bag holder 3 and the insufflation and suction means are fully retracted and located in the proximal position at least partially inside of the conduit of the tubular element 2. On the other hand, the bag 5 with the sample, compacted and molded to the elongated shape, is coupled to the adaptation means 9 of the abdominal wall so that both are arranged one after the other, presenting a continuity in the shape of the bag 5, with respect to the adaptation means 9.
• Extracción del dispositivo quirúrgico 1. Finalmente, se procede a extraer los diferentes elementos hasta extraer el elemento de accionamiento 10 y el elemento tubular 2 alargado, dejando en el interior del cuerpo la bolsa 5 y los medios de adaptación 9, de los cuales se procede a estirar de la cuerda de tracción 6 hasta extraer todo el conjunto del cuerpo humano a través del orificio realizado, de una forma que permite dilatar paulatinamente la pared abdominal.  • Removal of the surgical device 1. Finally, the different elements are removed until the actuating element 10 and the elongated tubular element 2 are removed, leaving inside the body the bag 5 and the adaptation means 9, of which It proceeds to stretch the pulling rope 6 until the entire human body is removed through the hole made, in a way that allows the abdominal wall to gradually dilate.
En la Fig. 6 se ilustra a la bolsa 5, para un ejemplo de realización, para el que ésta está formada por un elemento laminar o capa exterior 5a, definiendo un envoltorio exterior con una embocadura superior, y un elemento laminar o capa interior 5b, definiendo un envoltorio interior también con una embocadura superior. In Fig. 6 the bag 5 is illustrated, for an exemplary embodiment, for which it is formed by a laminar element or outer layer 5a, defining a wrapper outer with an upper mouth, and a laminar element or inner layer 5b, defining an inner wrap also with an upper mouth.
El envoltorio exterior se encuentra unido al envoltorio interior por una zona próxima a sus embocaduras mediante una línea de unión t, por ejemplo creada por termo sellado, de manera que se accede al interior de la bolsa 5 para insertar una pieza quirúrgica a través de la embocadura del envoltorio interior. La unión realizada mediante dicha línea de unión t deja, para el ejemplo de realización ilustrado, una pequeña porción de la embocadura del envoltorio exterior abierta de manera que pueda insuflarse el fluido, por ejemplo aire, al interior de la cámara intermedia 14, según la flecha E indicada en la Fig. 6.  The outer wrapper is attached to the inner wrapper by an area close to its mouths by means of a junction line t, for example created by heat sealing, so that the inside of the bag 5 is accessed to insert a surgical piece through the mouth of the inner wrap. The connection made by said joint line t leaves, for the illustrated embodiment, a small portion of the open outer mouth opening so that the fluid, for example air, can be blown into the intermediate chamber 14, according to the arrow E indicated in Fig. 6.
Las dos capas 5a, 5b también se encuentran unidas por otras líneas de unión C (en este caso en un número de cuatro), como se ilustra en las Figs. 7 y 8, realizadas por ejemplo mediante unas respectivas cintas adhesivas de doble cara, de manera que la cámara intermedia 14 se encuentra formada por cuatro sub-cámaras 14a, 14b, 14c y 14d (ver Fig. 8) cada una de ellas delimitada por dos de dichas líneas de unión C.  The two layers 5a, 5b are also joined by other joining lines C (in this case in a number of four), as illustrated in Figs. 7 and 8, made for example by means of respective double-sided adhesive tapes, so that the intermediate chamber 14 is formed by four sub-chambers 14a, 14b, 14c and 14d (see Fig. 8) each delimited by two of said connecting lines C.
En las Figs. 7 y 8 se ilustran sendas vistas en sección transversal de la bolsa de la Fig. 6, realizada a través del plano de corte indicado por la línea de corte A-A, donde la Fig. 7 ilustra una situación previa a la compactación y moldeo de la pieza quirúrgica P contenida en su interior y la Fig. 8 muestra una situación de uso en la que las sub- cámaras 14a, 14b, 14c y 14d están llenas de fluido, tal como aire, y presionando a la pieza quirúrgica P, compactándola y moldeándola hasta adquirir una forma largada.  In Figs. 7 and 8 illustrate two cross-sectional views of the bag of Fig. 6, made through the cutting plane indicated by the AA cutting line, where Fig. 7 illustrates a situation prior to compacting and molding the surgical part P contained therein and Fig. 8 shows a use situation in which the sub-chambers 14a, 14b, 14c and 14d are filled with fluid, such as air, and pressing the surgical part P, compacting it and molding it to acquire a long form.
Como puede verse en la Fig. 8, parte de las sub-cámaras se tocan entre sí por sus respectivas porciones de la capa interior 5b que las delimita en parte. En concreto, la sub-cámara 14a está tocando a las sub-cámaras 14b y 14d. La presión suministrada por los medios de insuflación es la suficiente como para que se produzca la situación ilustrada en la Fig. 8, es decir que las sub-cámaras 14a, 14b, 14c y 14d presionen a la pieza quirúrgica P lo suficiente como para compactarla y moldearla.  As can be seen in Fig. 8, part of the sub-chambers touch each other by their respective portions of the inner layer 5b that partially delimits them. Specifically, the sub-chamber 14a is touching the sub-cameras 14b and 14d. The pressure supplied by the insufflation means is sufficient to produce the situation illustrated in Fig. 8, that is to say that the sub-chambers 14a, 14b, 14c and 14d press the surgical part P enough to compact it. and mold it.
Un experto en la materia podría introducir cambios y modificaciones en los ejemplos de realización descritos sin salirse del alcance de la invención según está definido en las reivindicaciones adjuntas.  A person skilled in the art could introduce changes and modifications in the described embodiments without departing from the scope of the invention as defined in the appended claims.
