Abstract
Abstract A hemostatic clip applicator (2) 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 (32,34) attached to one end of the main body, clip feed means (18) located within the main body and actuating means (5, 7) 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.
