Multi-fire surgical clip applier
First Claim
1. A clip applier for applying a surgical clip, the applier comprising:
- a cartridge with a proximal end and a distal end and including;
a feeder having a proximal end and a distal end,a closure member having a proximal end, a distal end, and a slot formed therein,a pair of symmetrical opposing crimping members extending outwardly from the distal end of the closure member, anda rack mechanism having a spur gear disposed on a spindle, a first rack connected to the feeder, and a second rack connected to the closure member, wherein the spindle extends through the slot in the closure member such that the spur gear interfaces with the second rack; and
an actuator coupled to the proximal end of the cartridge and the proximal end of the closure member, the actuator arranged to open the opposing crimping members during an opening stroke and the closure member and the second rack arranged to move synchronously throughout the opening stroke.

Abstract
Clip appliers to apply a surgical clip and methods concerning the same are provided. One provided applier has a cartridge and an actuator. The rack mechanism causes a feeder to move proximally as a closure member moves distally, such that jaw members move together to crimp a clip there between. The rack mechanism also causes the feeder to move distally as the closure member moves proximally, such that a crimped clip is released and another clip is fed into the jaw members. The rack mechanism further includes a rack connected to the closure member in which the closure member and the rack are arranged to move synchronously throughout the releasing of a crimped clip and feeding of another clip, e.g., an opening stroke.
