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.
