Descripción de una realización preferida de Ia invención Mediante el dispositivo de Ia invención, Ia pinza (11 , 12) que se aloja en el extremo distal, se puede colocar en el interior del cuerpo humano, en posición cerrada y ejerciendo una cierta presión, por medio de un dispositivo elástico.Description of a preferred embodiment of the invention By means of the device of the invention, the clip (11, 12) that is housed at the distal end, can be placed inside the human body, in a closed position and exerting a certain pressure, by middle of an elastic device.
De acuerdo con una realización de Ia invención, durante una operación se puede utilizar el trocar (2) o tubo por donde se introduce cualquier instrumento en laparoscopia, en este caso, por donde se ha introducido Ia pinza (11 , 12), y ésta al estar cerrada, ocluye el intestino, un vaso sanguíneo, o cualquier órgano tubular, es decir, ejerce su misión durante el tiempo que sea pertinente. Finalmente, se recupera de nuevo: primero se inserta en el tubo (3), donde un sistema mecánico de blocaje (21 , 22, 23) que comprende un número variable de uñetas (23) Io amarra, y una vez hecho esto, a través de un empujador (1 ) se fuerza Ia apertura de Ia pinza (11 , 12). Todo el sistema es estanco.According to an embodiment of the invention, during an operation the trocar (2) or tube can be used through which any instrument is inserted into laparoscopy, in this case, where the clamp (11, 12) has been introduced, and this when closed, it occludes the intestine, a blood vessel, or any tubular organ, that is, it exercises its mission for as long as it is relevant. Finally, it is recovered again: first it is inserted into the tube (3), where a mechanical locking system (21, 22, 23) comprising a variable number of fingernails (23) ties it, and once done, to The opening of the clamp (11, 12) is forced through a pusher (1). The whole system is tight.
El dispositivo de Ia invención comprende medios de accionamiento (31 , 32, 33, 34) en el extremo de manipulación que tienen: medios de fijación/liberación (33) de Ia pinza (11 , 12) entre una posición fijada, y liberada; medios de apertura/cierre (32) de Ia pinza (11 , 12) entre una posición cerrada y abierta.The device of the invention comprises actuation means (31, 32, 33, 34) at the handling end which have: fixing / releasing means (33) of the clamp (11, 12) between a fixed and released position; opening / closing means (32) of the clamp (11, 12) between a closed and open position.
Estos medios de accionamiento pueden comprender cilindros rotativos (31 , 32, 34) para fijar/desprender Ia pinza (11 , 12). El dispositivo de Ia invención también permite ser manipulado con otras variantes de mangos utilizadas en este tipo de instrumental.These drive means may comprise rotary cylinders (31, 32, 34) to fix / detach the caliper (11, 12). The device of the invention It also allows to be manipulated with other variants of handles used in this type of instruments.
La pinza (11 , 12) tiene un acoplamiento que permite que su extremo útil pueda ser desprendido del tubo (3) ejerciendo su función mientras deja libre el trocar (2) de inserción para ser utilizado por otro instrumento; este mismo acoplamiento permite liberar con facilidad Ia presión y recuperar el extremo distal.The clamp (11, 12) has a coupling that allows its useful end to be detached from the tube (3) exerting its function while leaving the insert trocar (2) free to be used by another instrument; This same coupling allows to easily release the pressure and recover the distal end.
Lo novedoso del dispositivo de Ia invención es que se puede abandonar Ia pinza (11 , 12) mientras se está actuando en el interior del cuerpo, al separar Ia pinza (11 , 12) del tubo (3). Esto permite dejar libre el trocar (2) (dispositivo por el que se introducen distinto instrumental quirúrgico en cirugía endoscópica) para introducir otros instrumentos, y más tarde puede recuperarse Ia pinza (11 , 12) abandonada.The novelty of the device of the invention is that the clamp (11, 12) can be abandoned while acting inside the body, by separating the clamp (11, 12) from the tube (3). This allows the trocar (2) to be released (device through which different surgical instruments are introduced in endoscopic surgery) to introduce other instruments, and later the abandoned clamp (11, 12) can be recovered.
En Ia fig. 2 puede apreciarse que el aparato posee una acoplamiento mecánico (21 , 22, 23) que permite desprender Ia pinza (11 , 12) para ser abandonada en el interior del organismo, para su posterior recuperación cuando sea necesario. Una vez desprendida Ia pinza (11 , 12), ésta mantiene su fuerza de cierre sobre el órgano tubular sobre el que ha sido colocada. El acoplamiento mecánico (21 , 22, 23) comprende un número variable de dispositivos mecánicos (23) que ejercen una fuerza prensil sobre Ia pinza (11 ,In fig. 2 it can be seen that the apparatus has a mechanical coupling (21, 22, 23) that allows the clip (11, 12) to be detached to be abandoned inside the body, for later recovery when necessary. Once the clip (11, 12) is detached, it maintains its closing force on the tubular organ on which it has been placed. The mechanical coupling (21, 22, 23) comprises a variable number of mechanical devices (23) that exert a prehensile force on the clamp (11,
12), manteniéndola unida al resto de dispositivo.12), keeping it attached to the rest of the device.
En Ia fig. 3, se muestra una realización de dichos dispositivos mecánicos (23), en número de tres. La fuerza prensil se ejerce a través del extremo más alejado de Ia pinza (11 , 12), con un dispositivo similar a unas tijeras o cualquier otro que permita elegir entre una posición abierta y una posición cerrada.In fig. 3, an embodiment of said mechanical devices (23), in number of three, is shown. The prehensile force is exerted through the furthest end of the clamp (11, 12), with a device similar to scissors or any other that allows choosing between an open position and a closed position.
En Ia fig. 1 se muestra otra realización, consistente en este caso en Ia rotación de uno de los cilindros respecto de otros (31 , 32, 33). Este dispositivo de amarre (21 , 22, 23) permite tanto abandonar Ia pinza (11 , 12) como su posterior recuperación. Por último, un sistema basado en un vastago (1 ) fuerza Ia apertura de Ia pinza. In fig. 1 shows another embodiment, consisting in this case in the rotation of one of the cylinders with respect to others (31, 32, 33). This mooring device (21, 22, 23) allows both abandoning the clamp (11, 12) and its subsequent recovery. Finally, a system based on a rod (1) forces the opening of the clamp.
