Abstract

A hemostatic clip applicator tool includes a replacable magazine for storing a series of clips, a dispensing mechanism for advancing clips from the magazine, and an applicator tip which receives the advanced clip and closes the same to a controlled degree of clamping pressure.

Claims

1. A hemostatic clip applicator comprising:

a magazine for holding a plurality of hemostatic clips in a compact array, said magazine having an open ended exit passage;

a base plate having means for detachably holding said magazine, a handle, and a clip applicator tip in alignment with said exit passage of said magazine;

a trigger pivotally attached to said base plate; and

a clip dispensing mechanism carried by said base plate and actuated by said trigger, said mechanism having a pawl movable into said exit passage and means for moving said pawl to advance a clip through said applicator tip.

2. The hemostatic clip applicator of claim 1 wherein said applicator tip includes a pair of plates each having a first end pivotally connected to said base plate and a second end and engaging the upper and lower faces, respectively, of a clip being moved therethrough.

3. The hemostatic clip applicator of claim 2 further including means for simultaneously adjusting the separation of said second ends of said plates to thereby determine the degree to which a clip is closed upon movement through said applicator tip.

4. The hemostatic clip applicator of claim 1 wherein said magazine has a spiral clip storage chamber, said exit passage extending tangentially from the outermost turn of said chamber.

5. The hemostatic clip applicator of claim 4 wherein said applicator tip includes a pair of plates pivotally connected to said base plate and engaging the upper and lower faces, respectively, of a clip being moved therethrough.

6. The hemostatic clip applicator of claim 5 further including means for simultaneously adjusting the separation of the free ends of said plates to thereby determine the degree to which a clip is closed upon movement through said applicator tip.

7. The hemostatic clip applicator of claim 5 wherein said magazine is a single-use, disposable item and includes means to prevent reloading thereof.
