A surgical clip applying device having a main body, a clip magazine coupled to the main body for holding a plurality of clips, clip deforming jaws coupled to the main body for receiving and deforming clips, a clip loading mechanism for loading clips from the magazine to a clip feed blade which moves clips from the clip magazine to the deforming jaws, and a spring activated actuating mechanism. The clip loading mechanism includes a double ratchet apparatus coupled to a pawl for advancing the clips through the magazine. The actuating mechanism includes handle portions, a ratchet member having a cam follower which is coupled to a camming surface which is in turn coupled to one of the handle portions, a spring connected to the main body and the ratchet member, and a latch adapted to engage the ratchet member. By movement of one of the handle portions with respect to the other handle portion, the camming surface engages the cam follower to store energy in the spring, which is 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. This forward movement causes the clip loading mechanism to advance a clip and, in addition, causes the clip feed blade to slide through the magazine to rapidly place a clip in the deforming jaws.

Spring activated hemostatic clip applicator

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. This forward movement causes the clip feed blade to slide through the magazine and rapidly place a clip in the deforming jaws.

A magazine for a hemostatic clip applicator useful in the rapid and automatic application of hemostatic clips for the strangulation of tubular members. The magazine has a housing wherein a plurality of clips are stored. A clip loading mechanism disposed within the housing urges the clips through the housing to a clip feed mechanism. The clip feed mechanism sequentially moves the clips to a clip deforming mechanism of the clip applicator.

Hemostatic clip applicator

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.

Surgical stapler

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.

A hemostatic clip useful in the strangulation of tubular members and formed of elongate deformable material is disclosed. The clip consists of a pair of arms coupled at one end and open at the other, the arms being separated in a substantially opposed relationship and each having a flat surface facing inwardly. Located in the flat surfaces of the arms are diagonal recesses. The recesses in opposing surfaces are arranged so as to be angularly displaced with respect to one another such that when the surfaces are brought into contact the recesses on opposing surfaces form a cross-hatched pattern.
