3. A cartridge for use with a surgical device, particularly for use with hemostatic forceps, comprising
a housing having a track provided with an outlet; -
means for advancing a string of surgical clips in direction towards said outlet so that the respectively leading clips of the string are sequentially discharged from the outlet to become cinched by jaws of the surgical device; and means for retracting the clips located upstream of the respective leading clip counter to said direction and away from said outlet prior to cinching of the discharged leading clip, so as to avoid interference by the upstream clips with such cinching, said retracting means comprising a retracting member mounted for movement between said leading clip and its adjacent clip for urging said adjacent clip and the successive clips away from said anvils; and means maintaining said housing stationary while said clips are being retracted. - View Dependent Claims (4)
