  • Patent number: 11090052
    Abstract: An end effector for a surgical clip applier includes a housing, opposed first and second jaw members extending past a distal end of the housing and each comprising an independent structure movable relative to the other, a first cam track provided on the first jaw member and a second cam track provided on the second jaw member, and a cam providing first and second cam surfaces slidably engageable with the first and second cam tracks, respectively. A biasing device continuously urges the cam in a distal direction relative to the first and second jaw members, wherein the first and second cam surfaces and the first and second cam tracks are angled such that axial movement of the cam in the distal direction relative to the first and second jaw members causes the jaw members to close.

  • Publication number: 20200297347
    Abstract: A surgical clip applier is provided that includes first and second jaws on a distal end of an elongate shaft, a clip advancing assembly extending through the shaft and configured to advance a distal-most clip from a plurality of clips in the shaft into the first and second jaws. The jaws have opposed inward facing surfaces, and each inward facing surface has a clip track defined therein for receiving and guiding legs of a clip into the first and second jaws. The clip track of at least one of the jaws has at least one deflectable clip retention member disposed therein and configured to apply a biasing force to a leg of a clip disposed within the jaws to thereby retain the clip within the jaws and maintain alignment of the clip with respect to the jaws. The clip track of at least one of the jaws may also have at least one recess or protrusion designed to be complementary to and mate with a protrusion or recess in a clip.
