Patent Images
1. A surgical clip applier, comprising:
- a housing;
at least one handle pivotably connected to the housing;
a channel assembly extending distally from the housing, the channel assembly including a camming surface;
a clip carrier disposed within the channel assembly and defining a channel therein;
a plurality of clips slidably disposed within the channel of the clip carrier;
a jaw assembly including a pair of jaws extending from an end of the channel assembly, opposite the housing, the jaw assembly configured to accommodate a clip therein and being operable to effect formation of the clip in response to movement of the at least one handle;
a clip pusher bar slidably supported within at least one of the housing and the channel assembly, the clip pusher bar having a first end operatively connected to the at least one handle and at least one flexible tab; and
a camming plate slidably supported within the channel assembly and configured to effectuate closure of the pair of jaws, the camming plate including a lost motion portion, the at least one flexible tab of the clip pusher bar being configured to;
engage the lost motion portion during an initial movement of the clip pusher bar to cause the camming plate to move with the clip pusher bar; and
disengage from the lost motion portion during a subsequent movement of the clip pusher bar to allow the clip pusher bar to move relative to the camming plate, wherein the camming surface of the channel assembly is configured to disengage the at least one flexible tab from the lost motion portion.

Abstract
A surgical clip applier is provided including a clip pusher bar having a flexible tab and a camming plate configured to effectuate closure of the pair of jaws. The camming plate includes a lost motion portion and the flexible tab is configured to engage the lost motion portion during an initial movement of the clip pusher bar to cause the camming plate to move with the clip pusher bar. The flexible tab is configured to disengage from the lost motion portion during a subsequent movement of the clip pusher bar to allow the clip pusher bar to move relative to the camming plate.

15. A surgical clip applier, comprising:
-
a housing; at least one handle pivotably connected to the housing; a channel assembly extending distally from the housing; a clip carrier disposed within the channel assembly and defining a channel therein; a plurality of clips slidably disposed within the channel of the clip carrier; a jaw assembly including a pair of jaws extending from an end of the channel assembly, opposite the housing, the jaw assembly configured to accommodate a clip therein and being operable to effect formation of the clip in response to movement of the at least one handle; a clip pusher bar slidably supported within at least one of the housing and the channel assembly, the clip pusher bar having a first end operatively connected to the at least one handle and at least one flexible tab, the clip pusher bar including a distal window; and a camming plate slidably supported within the channel assembly and configured to effectuate closure of the pair of jaws, the camming plate including a lost motion portion and a proximal flange, the at least one flexible tab of the clip pusher bar being configured to; engage the lost motion portion during an initial movement of the clip pusher bar to cause the camming plate to move with the clip pusher bar; and disengage from the lost motion portion during a subsequent movement of the clip pusher bar to allow the clip pusher bar to move relative to the camming plate, wherein the proximal flange of the camming plate is configured to be received within the distal window of the clip pusher and engaged with a distal end of the distal window when the clip pusher bar moves proximally to move the camming plate proximally.
