Abstract
A cartridge is disclosed suitable for use in a surgical clip applicator. The cartridge includes a pair of channels for the receipt of a supply of clips. A clip pusher is biased toward the clip supply by a spring in order to feed the clips forwardly. Movement of the pusher is arrested or permitted by operation of a switch button which controls a triangular locking member. In a first position the locking member engages the bottom of the cartridge to prevent forward movement while in a second position the locking member permits forward movement of the pusher.
