Two-part surgical ligation clip
First Claim
1. A two-part surgical ligation clip, comprising:
- a track including two substantially symmetrical arms connected together at a proximal end to form an apex and having spaced tips at a distal end with first complementary surfaces, said track also including a connector to said apex and having a second complementary surface; and
a clip having an extended slot for slidably engaging said track and distal end tips for receiving said connector, with a distal end of said clip having a first contour surface and a second contour surface, whereinsaid first contour surface engages and interlocks with said first complementary surfaces on said track to lock said track in a closed position, said second contour surface engages and interlocks with said second complementary surface on said track to lock said track in an open position.

Abstract
A two-part surgical ligation clip includes a track having two substantially symmetrical arms and a clip for slidably receiving the track. The symmetrical arms are connected together at a proximal end to form an apex and have spaced-apart tips at a distal end with first complementary surface. The track also includes a connector connected to the apex and having a second complementary surface. The clip has an extended slot for slidably engaging the track and distal end tips for receiving the connector. A distal end of the clip has a first contour surface for engaging the first complementary surface on the track and locking it in a closed position and a second contour surface for engaging the second complementary surface on the track and locking it in an open position.

14. A surgical ligation clip, comprising:
-
a track having two arms for engaging around a vessel to be ligated, said arms being joined together at a proximal end of said track; a clip having an extended slot for slidably receiving said track; first interlocking means, located at distal ends of said track and said clip, for engaging and interlocking said track in a closed position in said clip; and second interlocking means, located at the distal end of said clip and the proximal end of said track, for engaging and interlocking said track in an open position in said clip. - View Dependent Claims (15, 16, 17, 18)

19. A surgical ligation clip, comprising:
-
a track having two arms for engaging around a vessel to be ligated, said arms being joined together at a proximal end of said track; a clip having an extended slot for slidably receiving said track; first locking means, located at distal ends of said track and said clip, for locking said track in a closed position in said clip; and second locking means, located at the distal end of said clip and the proximal end of said track, for locking said track in an open position in said clip, wherein said first locking means includes a first complementary surface at the distal end of each said arm and a first contour surface at the distal end of said clip, said second locking means includes a connector, connected to the proximal end of said track, having a second complementary surface, and a second contour surface located at the distal end of said clip, and wherein said first complementary surface is formed by large windows disposed at distal ends of said arms, and further comprising a pair of keys forming said first contour surface the distal end of said clip, and said connector comprises two posts each having a substantially T-shaped cross-section and chamfered edges to form said second complementary surface, and said second contour surface is formed by a notched portion contiguous with a chamfered surface at the distal end of said clip. - View Dependent Claims (20, 21, 22, 23, 24)

25. A two-part surgical ligation clip, comprising:
-
a track including two substantially symmetrical arms connected together at a proximal end to form an apex and having spaced tips at a distal end, said track also including a connector connected to said apex and formed with a first complementary surface; and a clip having an extended slot for slidably engaging said track and distal end tips for receiving said connector, with a distal end of said clip having a first contour surface, wherein said first contour surface is formed to receive said first complementary surface on said track and thereby to lock said track in an open position, and one of said first complementary surface and said first contour surface comprises a notch and the other of said first complementary surface and said first contour surface comprises post means formed to be received in said notch, thereby to lock said track in an open position relative to said clip. - View Dependent Claims (26, 27)
