Abstract: A surgical clip applying device having a main body, a clip magazine coupled to the exterior of the main body for holding a plurality of clips, clip deforming jaws coupled to the main body for receiving and deforming clips, a clip feed blade for moving clips from the clip magazine to the deforming jaws, and a spring activated actuating mechanism. The actuating mechanism includes handle portions, a ratchet member connected to the handle portions, a spring connected to the main body and the ratchet member, along with a latch adapted to engage the ratchet member. By movement of one of the handle portions with respect to the other handle portion energy is stored in the spring and retained therein via engagement of the latch with the ratchet member. In operation, a slight movement of one of the handle portions with respect to the other handle portion disengages the latch from the ratchet member so that the energy stored in the spring is converted into rapid forward movement of the clip feed blade.

Abstract: A hemostatic clip applicator useful in the rapid and automatic application of hemostatic clips for the strangulation of tubular members is disclosed. The applicator consists of a main body, a clip magazine externally attached to the main body, clip deforming jaws attached to one end of the main body, clip feed means located within the main body and actuating means attached to the feed means and deforming jaws. In operation, one of many hemostatic clips stored in the clip magazine is fed into the main body and guided to the deforming jaws by the interaction of the actuating means and the feed means. When the clip is properly located about a tubular member, further actuation of the actuating means results in the deformation of the clip about the tubular member. Upon further activation of the actuating means, the sequential process of feeding a clip from the magazine and deforming the clip about other tubular members may be rapidly repeated until the supply of clips in the magazine is depleted.
