Asymmetric clip applier and cartridge
A clip applier may include: a first jaw member for engaging a first leg member of a surgical clip; and a second jaw member for engaging a second leg member of the surgical clip. At least one of the first jaw member and the second jaw member is asymmetric about a medial plane of the clip applier. A clip cartridge may include: a base having a first axis and a second axis, the second axis being perpendicular to the first axis; and a plurality of walls defining at least one cavity for receiving the surgical clip. At least one of the plurality of walls has a first wall portion on a first side of the first axis and a second wall portion on a second side of the first axis. The first wall portion and the second wall portion are offset to each other with respect to the second axis.
1 . A clip applier configured to apply a surgical clip, the clip applier comprising:
a first jaw member configured to engage a first leg member of the surgical clip, the first jaw member including a first longitudinal wall and a second longitudinal wall;
a second jaw member configured to engage a second leg member of the surgical clip, the second jaw member including a third longitudinal wall and a fourth longitudinal wall;
a first longitudinal channel separating the first and second longitudinal walls of the first jaw member; and
a second longitudinal channel separating the third and fourth longitudinal walls of the second jaw member;
wherein at least one of the first jaw member and the second jaw member is asymmetric about a medial plane of the clip applier, and
wherein a distal portion of the first longitudinal wall has a first width, a distal portion of the second longitudinal wall has a second width, a distal portion of the third longitudinal wall has a third width, a distal portion of the fourth longitudinal wall has fourth width, and the first width is greater than the second width and/or the third width is greater than the fourth width.
2 . The clip applier of claim 1 , wherein both of the first jaw member and the second jaw member are asymmetric about the medial plane of the clip applier.
3 . The clip applier of claim 1 , wherein at least one of the first and second jaw members has a first width on a first side of the medial plane of the clip applier and a second width on a second side of the medial plane of the clip applier, and the first width is greater than the second width.
4 . The clip applier of at claim 1 , wherein the first jaw member includes a first longitudinal channel extending through a distal end of the first jaw member, and/or the second jaw member includes a second longitudinal channel extending through a distal end of the second jaw member.
5 . The clip applier of claim 1 , wherein the first jaw member includes at least one first recess configured to receive at least one boss on the first leg member, the second jaw member includes at least one second recess configured to receive at least one boss on the second leg member, and at least one of the first jaw member and the second jaw member are asymmetric about the medial plane of the clip applier along the at least one first recess and the at least one second recess.
6 . The clip applier of claim 5 , wherein the first jaw member has a closed lateral side of the at least one first recess, and the second jaw member has a closed lateral side of the at least one second recess.
7 . The clip applier of claim 5 , wherein the at least one first recess of the first jaw member has an open lateral side and a closed lateral side, and the at least one second recess of the second jaw member has an open lateral side and a closed lateral side.
8 . The clip applier of claim 1 , wherein at least one of the first and second jaw members includes a stabilizing member configured to laterally stabilize a proximal portion of the surgical clip when the surgical clip is in an open configuration.
9 . The clip applier of claim 8 , further comprising a longitudinal channel in at least one of the first and second jaw members configured to receive the stabilizing member of the at least one of the first and second jaw members when the clip applier is in a closed configuration.
10 . The clip applier of claim 8 , wherein the first jaw member includes a first stabilizing member, the second jaw member includes a second stabilizing member, and the first stabilizing member and the second stabilizing member are configured to receive the proximal portion of the surgical clip when the surgical clip is in an open configuration.
11 . A clip applier system comprising:
the clip applier of claim 1 ; and
a clip cartridge having at least one cavity configured to receive the clip applier to load the surgical clip, wherein the at least one cavity is asymmetric about a medial plane.
12 . The clip applier system of claim 11 , wherein the at least one cavity is formed by offset wall portions of the clip cartridge.
