Abstract

A hemostatic clip device capable of being mounted to a surgical applicator and applied to a blood vessel so as to prevent blood flow. The clip device includes a pair of semi-rigid legs having free ends and opposed ends connected to a bridge. The legs are movable from an open mode in the applicator to a closed mode pinching the blood vessel. A plurality of first grooves are formed in parallel on one of the legs in a slanted direction relative to longitudinal dimension of the legs. A plurality of second grooves are formed in parallel on the other leg in a slanted direction relative the dimension of the legs approximately perpendicular to the second grooves so that the crimped vein remains stationary. A locking tab formed at the end of one of the legs is adapted to slide into a recess at the inner side of the opposed leg to prevent cross movement of the legs.

Claims

1. A hemostatic ligating clip device for closing the tube of a blood vessel capable of being applied by a clip applicator, comprising, in combination,

a pair of opposed, flexible, semi-rigid, elongated, first and second leg members having first and second connecting ends, opposed first and second free ends, and facing first and second inner sides, respectively, said first and second leg members extending in a longitudinal dimension between said first and second connecting ends and said first and second free ends, respectively,

a flexible, semi-rigid bridge portion having opposed ends connected to said first and second connecting ends,

said leg members being movable from an open mode wherein said clip device is mounted in said clip applicator and said leg members are spaced apart, to a closed mode wherein said clip device has been applied to said blood vessel and said leg members are separated by the wall of said blood vessel, said first and second leg members being in proximate association and positioned in said longitudinal dimension substantially transverse to said blood vessel,

a plurality of first grooves formed in said first leg member at said first side in parallel relationship at a first slant relative to said longitudinal dimension wherein said blood vessel is inhibited from sliding between said first and second leg members in a first direction transverse to said first slant,

a plurality of second grooves formed in said second leg member at said second side in parallel relationship at a second slant relative to said longitudinal direction wherein said blood vessel is inhibited from sliding between said leg members in a second direction transverse to said second slant, said first and second slants being generally in transverse relationship, and

wherein said first and second leg members form first and second inner channels, respectively, at the centers of said first and second facing sides along said longitudinal dimension, said first and second channels being in general opposed relationship when said leg members are in said closed mode, said blood vessel being spaced inwardly from said first and second free ends, said first leg member having a locking tab extending outwardly from said first channel at said first free end toward said second leg member, said second channel of said second leg member being adapted to receive said locking tab at said second free end, wherein in said closed mode said first and second leg members are prevented from cross-movement relative to one another and relative to said longitudinal dimension.

2. The clip device according to claim 1, wherein said first and second grooves are positioned so as to cross each other along said longitudinal direction when said leg members are in said closed mode.

3. The clip device according to claim 2 wherein said first and second grooves form crosses at approximate right angles.

4. The clip device according to claim 3, wherein said longitudinal dimension includes a longitudinal midplane, said first and second grooves being at approximate 45 degree angles from said midplane.

5. The clip device according to claim 1, wherein said first and second leg members have first and second outer sides opposed to said first and second inner sides, said bridge member having an arcuate outer side joining said first and second outer sides, said first and second leg members forming first and second outer channels at the center of said first and second outer sides that join to said arcuate outer side, whereby said outer channel is adapted to be held by said applicator when said first and second leg members are in said open mode and during the time of moving said first and second leg members from said open mode to said closed mode.

6. The clip device according to claim 5, wherein said bridge member has an arcuate inner side opposed to said arcuate outer side, said arcuate inner side forming a notch, whereby said bridge member is capale of being readily bent when said first and second leg members are moved from said open mode to said closed mode.

7. The clip device according to claim 1, wherein said clip device is made of metal.
