ABSTRACT:
A surgical clip applier includes a housing, a pair of handles pivotably connected to opposite sides of the housing, a channel assembly which is anchored to the housing and a jaw assembly which is anchored to the channel assembly. The jaws are opened and closed by a cam plate which is slidably positioned in the channel assembly and is provided with cam slots at its distal end to engage drive rivets positioned on the jaw members. A pusher bar assembly is also provided to feed clips from a series of clips to the jaw mechanism, and the instrument operates such that all moving components move in the same direction during the closing stroke of the handle, and then move in the same direction opposite to the closing direction when the handles are in the opening stroke. A novel lockout mechanism is also provided to render the instrument inoperable after all the clips have been utilized from the instrument.
