A tissue ligation assembly may include a surgical clip and a clip applier. The clip applier may include a first jaw member and a second jaw member for closing and/or latching the surgical clip onto tissue. The surgical clip may be loaded in the clip applier and include first and second leg members for ligating tissue. The first leg member may include a first proximal portion, a first distal portion, a first inner surface, and a first outer surface. The first outer surface may engage and/or be received in the first jaw member of the clip applier. The second leg member may include a second proximal portion, a second distal portion, a second inner surface, a second outer surface, an inner portion, and an outer portion. The second outer surface may engage and/or be received in the second jaw member of the clip applier.

Surgical clip and clip applier

A clip applier is provided for applying a surgical clip to tissue. The clip applier may include a first jaw member that engages a first distal portion of the surgical clip, and a second jaw member that engages a second distal portion of the surgical clip. The first and second jaw members move relative to each other between an open configuration and a closed configuration. A first longitudinal channel extends through a first inner portion of the first jaw member and separates the first jaw member into a pair of first extensions. A first stabilizing member has a first distal end portion fixedly secured to the first jaw member inside of the first longitudinal channel, and a first proximal end portion that engages a first proximal portion the surgical clip to reduce movement of the surgical clip.

Flexible stabilizing member for a clip applier

A clip applier may be configured to apply a surgical clip to tissue. The clip applier may include a first jaw member, a second jaw member, and a stabilizing member, each configured to engage the surgical clip. The stabilizing member may be configured to move longitudinally with respect to the clip applier from a first position at least partially between the first and second jaw members to a second position at least partially between the first and second jaw members. The longitudinal movement of the stabilizing member may be constrained to longitudinal movement between the first and second positions. The stabilizing member may include first and second sidewalls on a distal portion, where the first and second sidewalls are configured to stabilize the surgical clip in a lateral direction. The clip applier may include a hinge pin received in a longitudinal channel of the stabilizing member.

Clip applier with stabilizing member

A clip applier may be configured to apply a surgical clip to tissue. The clip applier may include a first jaw member configured to engage a distal portion of a first leg member of the surgical clip, and a second jaw member configured to engage a distal portion of a second leg member of the surgical clip. The clip applier may further include a stabilizing member on the first jaw member. The stabilizing member may have a cavity configured to receive a proximal portion of the surgical clip and to reduce lateral movement of the surgical clip. The clip applier may not proximally abut the surgical clip when the first and second jaw members are in an open configuration. The second jaw member may also have a longitudinal channel configured to receive the stabilizing member when the first and second jaw members are in a closed configuration.

Clip applier having stabilizing member

A clip applier may be configured to apply a surgical clip and have a pair of jaw members. Each of the jaw members may have an inner surface and a stabilizing member extending from the inner surface. Each of the jaw members may be configured to engage a distal portion of a leg member of the surgical clip. The stabilizing members may be configured to be positioned on opposite lateral sides of a proximal portion of the surgical clip to reduce lateral movement of the surgical clip. An inner portion of each of the stabilizing members may be spaced apart from the opposing jaw member in an open configuration, and each of the jaw members may have a channel on the inner surface to receive the opposing stabilizing member in a closed configuration.

Clip applier

A surgical clip may include a first leg member having a first inner surface with a curvature, the first leg member having a first thickness in a vertical direction, a first width in a lateral direction, and a first length in a longitudinal direction, where the first width is greater than the first thickness along at least half of the first length. The surgical clip may also include a second leg member having a second inner surface with a curvature, the second leg member having a plurality of teeth. The first width may be defined by first and second lateral protrusion extending from opposing side surfaces of the first leg member. The first width may be greater than a second width of an inner portion of the first leg member and a third width of an outer portion of the first leg member.

Surgical clip

A clip applier assembly may include a surgical clip and a clip applier. The surgical clip may include first and second leg members configured to ligate tissue. The first leg member may include a first proximal portion, a first distal portion, a first inner surface, and a first outer surface. The first outer surface may have a convex curvature. The second leg member may include a second proximal portion, a second distal portion, a second inner surface, and a second outer surface. The second leg member may further include an inner portion and an outer portion separated by a channel. The second outer surface may be formed on the outer portion and have a convex curvature. The clip applier may have a first jaw member configured to engage the first outer surface and a second jaw member configured to engage the second outer surface.

A clip applier configured to apply a surgical clip to tissue. The clip applier may include first and second jaw members configured to engage distal portions of the surgical clip. The first and second jaw members may be configured to move relative to each other between an open configuration and a closed configuration. The clip applier may also include a stabilizing member having an end portion secured to the first jaw member. The stabilizing member may be configured to engage a proximal portion of the surgical clip and be compressed from a first configuration when the first and second jaw members are in the open configuration to a second configuration when the first and second jaw members are in the closed configuration. The stabilizing member may have at least one bend that facilitates compression of the stabilizing member.

A surgical clip may include a wire body having first and second free end portions. The surgical clip may also include first and second leg members connected by a hinge portion. The first leg member may include first and second segments of the wire body, the first segment may be spaced from the second segment, and the first and second free end portions may be disposed on a distal end portion of the first leg member. The second leg member may include third and fourth segments of the wire body, the third segment being spaced from the fourth segment. The hinge portion may join proximal end portions of the first and second leg members. The surgical clip may be movable between an open configuration and a closed configuration, wherein the second leg member is received between the first and second free end portions on the first leg member, and the first and second leg members pivot about the hinge portion to move the surgical clip between the open configuration and the closed configuration.

Latching wire clip

A method of securing a surgical clip to a clip applier may include engaging a first applier tip with a first jaw member, and engaging a second applier tip with a second jaw member. The jaw members may be secured within sleeve portions of the applier tips. The surgical clip may then be received between the first and second jaw members and secured with the first and second applier tips. The surgical clip may be secured to the clip applier by receiving a proximal portion of the surgical clip between a first protrusion of the first applier tip and a second protrusion of the second applier tip, receiving a first boss member on a first leg member of the surgical clip in a recess of the first applier tip, and receiving a second boss member on a second leg member of the surgical clip in a recess of the second applier tip.
