摘要:
An applicator instrument for dispensing surgical fasteners includes an elongated shaft, a housing connected with the elongated shaft, a trigger, a gear train, and a firing system disposed in the housing. The trigger is squeezed for commencing a firing cycle. The firing system includes a storage reel, a spool connected to the storage reel, a drive wheel located distal to the storage reel and the spool, a constant torque spring having a proximal end connected to the spool and a distal end connected to the drive wheel, and a flexible member in contact with the drive wheel. The flexible member has a proximal end connected to the storage reel and a length configured to be driven by the drive wheel toward the distal end of the elongated shaft. During an energy storing stage, the gear train is coupled with the storage reel for rotating the storage reel in a counterclockwise direction, which, in turn, retracts and winds the flexible member onto the storage reel, which rotates the drive wheel in a counterclockwise direction and winds the constant torque spring from the spool onto the drive wheel for storing energy in the constant torque spring.Un instrumento aplicador para dispensar sujetadores quirúrgicos incluye un vástago alargado, un alojamiento conectado con el vástago alargado, un disparador, un tren de engranajes y un sistema de disparo dispuesto en el alojamiento; el disparador se aprieta para comenzar un ciclo de disparo; el sistema de disparo incluye un carrete de almacenamiento, una bobina conectada al carrete de almacenamiento, una rueda de accionamiento ubicada distal al carrete de almacenamiento y la bobina, un resorte de torsión constante que tiene un extremo proximal conectado a la bobina y un extremo distal conectado a la rueda de accionamiento, y un miembro flexible en contacto con la rueda de accionamiento, el miembro flexible tiene un extremo proximal conectado al carrete de almacenamiento y una longitud configurada para ser impulsada por la rueda de acci
