Abstract
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, a laminated clip feed blade located within the clip magazine, and an actuating mechanism attached to the feed blade and deforming jaws. In operation, one of many hemostatic clips stored in the clip magazine is fed into the deforming jaws by the interaction of the actuating mechanism and the feed blade. This feeding of a hemostatic clip into the deforming jaws is a result of the clip feed means engaging a clip from the clip magazine, sliding into the deforming jaws so as to move that clip into the deforming jaws, and the retracting of the clip feed means from the deforming jaws. When the clip is properly located about a tubular member, further actuation of the actuating mechanism results in the deformation of the clip about the tubular member. Upon further activation of the actuating mechanism, 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.
