Abstract

Apparatus and method for hemostatically clipping an incision edge with normally biased spring clips. A magazine containing a plurality of said clips and means for conveying said clips through the magazine. A method for gathering the incision edge within a bridge, over and past which, the clip is forced thereby engaging the flesh member between the jaws of said clip.

Claims

1. An apparatus for dispensing jaw-type clips for use in achieving hemostasis along an incision edge, which comprises:

(a) clips, having two opposing surfaces which form a jaw, and means to bias said surfaces together,

(b) an elongated magazine for holding at least two of said clips, said magazine including means to direct the clips to one end thereof with the jaws of the clips in an open condition,

(c) guides, projecting from said one end of the magazine, said guides being adapted to gather that section of the incision edge to be hemostatically clipped, and

(d) means for conveying said clips through said magazine, toward and past said guides,

whereby in use, said guides position the incision edge between the open jaw of said clips, said conveying means pushes said clip over and past said guides, and whereupon the jaw of said clip closes around the incision edge to achieve hemostasis.

2. The apparatus of claim 1 wherein said clips have upper and lower quadrilateral surfaces which intersect at one edge to form the front of a jaw, and said surfaces are joined at their rear edges to the upper and lower edges, respectively, of a third face to form said surface biasing means.

3. The apparatus of claim 1 wherein said elongated magazine is a channel bounded by at least a lower surface and two side walls, said side walls each having a wedge attached thereto, said wedges are widest at the guide end of said magazine and run the length of the magazine to its other end where said wedges are narrowest, and wherein the clips are loaded into said other end of the magazine such that the wedges force open the clips'"'"' jaws so that as the clips are conveyed along the length of the magazine toward said guide end, their jaws are opened wider.

4. The apparatus of claim 1 wherein said conveying means comprises:

(a) a base having a key way;

(b) a magazine holder which is attached to said base;

(c) an elongated bar, passing through said keyway for movement relative thereto, said bar having a plate at one end thereof received within said magazine; and

(d) trigger operated bar forwarding means to selectively advance said bar into engagement with clips contained within the magazine, or permit said bar to be retracted for reloading of the magazine.

5. An apparatus according to claim 1 wherein said means to direct the clips to one end of the magazine includes divergent surfaces to spread the jaws of the clips as the clips are conveyed past the guides.

6. An improved method for hemostatically closing an incision in a flesh member, said improved method comprising:

engaging the flesh member to either side of the incision with a bridge spanning the incision;

directing a clip having normally engaged spring biased jaws over the bridge to spread the jaws of the clip; and

releasing said clip from the bridge to engage the flesh member to either side of the incision between said jaws.

7. The improved method of claim 6 wherein said clip is directed toward, and released from, said bridge by cooperation of an elongated magazine containing said clips and means for conveying said clips through said magazine, toward and past said bridge.

8. The improved method of claim 6 wherein said incision is closed by successively repeating the improved method steps, whereby a plurality of said clips engages the flesh members on either side of the incision.
