Endoscopic surgical clip applier with connector plate
First Claim
1. An apparatus for application of surgical clips to body tissue, the apparatus comprising:
- a handle assembly including a trigger and a drive bar, the drive bar being reciprocally translatable by the trigger upon a firing stroke thereof;
a shaft assembly extending distally from the handle assembly and defining a longitudinal axis, the shaft assembly including;
a housing having a stationary feature projecting therefrom;
a plurality of surgical clips disposed within the housing;
a jaw mounted adjacent a distal end portion of the housing, the jaw being movable between an open spaced-apart condition and a closed approximated condition;
a pusher bar reciprocally disposed within the housing, the pusher bar being configured to load a distal-most surgical clip into the jaws while the jaws are in the open condition and remain in a distal-most position during an approximation of the jaws, the pusher bar including a spring clip supported thereon for detachably connecting to the stationary feature of the housing when the push bar is at the distal-most position;
a wedge plate reciprocally disposed within the housing, the wedge plate being movable between a position where a distal end thereof is disposed in the jaws and a position where the distal end thereof is free from the jaws; and
a connector plate reciprocally disposed within the housing, wherein the connector plate detachably connects to each of the pusher bar and the wedge plate during at least a portion of the firing stroke of the trigger.

Abstract
An apparatus for application of surgical clips to body tissue is provided and includes a handle assembly; a shaft assembly including a housing extending distally from the handle assembly and defining a longitudinal axis; a plurality of surgical clips disposed within the shaft assembly; a jaw mounted adjacent a distal end portion of the shaft assembly, the jaw being movable between an open spaced-apart condition and a closed approximated condition; and a pusher bar reciprocally disposed within the housing of the shaft assembly and being detachably connectable to the housing of the shaft assembly, the pusher bar being configured to load a distal-most surgical clip into the jaws during distal movement and remain connected to the housing of the shaft assembly and in a distally advanced position during an approximation of the jaws.

19. An apparatus for application of surgical clips to body tissue, the apparatus comprising:
-
a handle assembly including a trigger and a drive bar, the drive bar reciprocally translatable by the trigger upon a firing stroke thereof; a shaft assembly extending distally from the handle assembly and defining a longitudinal axis, the shaft assembly including; a housing; a plurality of surgical clips disposed within the housing; a jaw mounted adjacent a distal end portion of the housing, the jaw being movable between an open spaced-apart condition and a closed approximated condition; a pusher bar reciprocally disposed within the housing, the pusher bar being configured to load a distal-most surgical clip into the jaws while the jaws are in the open condition and remain in a distal-most position during an approximation of the jaws; a wedge plate reciprocally disposed within the housing, the wedge plate being movable between a position where a distal end thereof is disposed in the jaws and a position where the distal end thereof is free from the jaws, the wedge plate including a spring clip supported thereon, a connector plate reciprocally disposed within the housing, wherein the connector plate detachably connects to each of the pusher bar and the wedge plate during at least a portion of the firing stroke of the trigger, the spring clip of the wedge plate connected to a feature of the connector plate during an initial distal movement of the connector plate to pull the wedge plate in a distal direction such that the distal end thereof is disposed in the jaws. - View Dependent Claims (20)
