Abstract

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.

Claims19

Dependent claims

A surgical clip comprising:

a first leg member having a first inner surface with a curvature and a pair of first outer side surfaces on opposite sides of the first leg member, the first inner surface extending laterally between the first outer side surfaces, 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, wherein the first width is greater than the first thickness along at least half of the first length, and wherein the first width is defined by at least one lateral protrusion extending from at least one of the first outer side surfaces of the first leg member;
and
a second leg member having a second inner surface with a curvature and a pair of second outer side surfaces on opposite sides of the second leg member, the second inner surface extending laterally between the second outer side surfaces, the second leg member having a plurality of teeth and a second width, wherein the second width is defined by the second outer side surfaces of the second leg member;
wherein the plurality of teeth of the second leg member are configured to extend past the first inner surface of the first leg member when the surgical clip is in a closed configuration,
wherein the plurality of teeth of the second leg member are configured to engage an inner surface of the at least one lateral protrusion when the surgical clip is in the closed configuration, and
wherein the first width of the first leg member is greater than the second width of the second leg member.

3 more elements

A surgical clip formed of a one-piece polymeric body, the surgical clip comprising:

a first leg member having a first inner surface with a concave curvature, a first outer surface, a first lateral protrusion extending from a first side surface, and a second lateral protrusion extending from a second side surface, the first leg member having a first thickness in a vertical direction defined between the first inner surface and the first outer surface, a first width in a lateral direction defined between the first lateral protrusion and the second lateral protrusion, and a first length in a longitudinal direction, wherein the first width is greater than the first thickness along at least half of the first length, the first width is greater than a second width of an inner portion of the first leg member, and the first width is greater than a third width of an outer portion of the first leg member;
a second leg member having a second inner surface with a convex curvature, the second leg member having a width and a plurality of teeth disposed laterally of the second inner surface, the width defined by opposite outer side surfaces of the second leg member, the plurality of teeth being configured to extend past the first inner surface when the surgical clip is in a closed configuration, and each of the plurality of teeth of the second leg member being configured to engage one of an inner surface of the first lateral protrusion and an inner surface of the second lateral protrusion when the surgical clip is in the closed configuration;
a hinge member pivotably joining the first leg member and the second leg member, wherein a proximal end of each of the first lateral protrusion and the second lateral protrusion is distal of the hinge member;
at least one boss member on a distal portion of the first leg member, wherein a distal end of each of the first lateral protrusion and the second lateral protrusion is proximal of the at least one boss member;
a hook member on a distal portion of the first leg member;
and
a tip member on a distal portion of the second leg member,
wherein the hook member is configured to receive the tip member to retain the surgical clip in the closed configuration, and
wherein the first width of the first leg member is greater than the width of the second leg member.
