Abstract
A surgical forceps comprising a first repositionable arm that includes a first prong extending distally therefrom and a second repositionable arm that includes a second prong extending distally therefrom, wherein each prong includes a distal flange that points inward and an interior surface of each prong is sloped. The surgical forceps may include a plurality of prongs for each arm. And the arms may be repositioned to reposition the prongs in order to bring the prongs closer together or farther apart. In exemplary form, the surgical forceps are adapted to grasp a semispherical device.
Claims27
A surgical forceps comprising:
- a first repositionable arm that includes a first prong extending distally therefrom, the first prong including a base mounted to the first repositionable arm where the first prong extends laterally outward from the base and distally away from the base, the first prong including a distal flange that extends laterally inward toward the base but stops short of overlapping the base, the first prong including a concave interior surface and a convex exterior surface, wherein the flange includes a widthwise dimension that is substantially greater than a thickness of the flange in a vertical direction;
- a second repositionable arm that includes a second prong extending distally therefrom, the second prong including a base mounted to the second repositionable arm where the second prong extends laterally outward from the base and distally away from the base, the second prong including a distal flange that extends laterally inward toward the base but stops short of overlapping the base, the second prong including a concave interior surface and a convex exterior surface, wherein the flange includes a widthwise dimension that is substantially greater than a thickness of the flange in a vertical direction;
- and,
- a third prong extending distally from the second repositionable arm, the third prong including a base mounted to the second repositionable arm where the third prong extends laterally outward from the base and distally away from the base, the third prong including a distal flange that extends laterally inward toward the base but stops short of overlapping the base, the third prong including a concave interior surface and a convex exterior surface, wherein the flange includes a widthwise dimension that is substantially greater than a thickness of the flange in a vertical direction;
- wherein an end of the flange of the first prong is oriented generally in the direction of the end of the flange of the second and third prongs;
- wherein the convex exterior surface of the first prong is oriented generally away from the convex exterior surface of the second and third prongs;
- wherein the concave interior of the first prong is oriented generally toward the concave interior of the second and third prongs;
- and,
- wherein an end of the flange of the third prong is oriented generally in the direction of the end of the flange of the second and third prongs.
6 more elements
A forceps comprising:
- a first arm and a second arm pivotally connected to each other, each of the first and second arms having opposing ends;
- a first jaw coupled to the first arm, the first jaw including at least one laterally outward bowed prong at least partially defining an interior concavity, the at least one laterally outward bowed prong includes a distal flange extending medially in a first plane;
- and
- a second jaw coupled to the second arm opposite the second finger hold, the second jaw including at least one medially outward bowed prong at least partially defining the internal concavity, the at least one medially outward bowed prong includes a distal flange extending laterally in the first plane.
1 more element
A forceps comprising:
- a first arm mounted to and repositionable with respect to a second arm;
- a first prong coupled to the first arm at a first junction having an X-axis that is perpendicular to a Y-axis that is perpendicular to a Z-axis that is itself perpendicular to the X-axis, the first prong extending proximally away from the first junction along the X-axis in a positive x-direction and laterally away from the first junction in the Y-axis in a positive y-direction, the first prong also including a distal flange that extends laterally toward the first junction in the Y-axis in a negative y-direction but does not overlap the first junction;
- and,
- a second prong coupled to the second arm at a second junction having the same coordinate system as the first prong, the second prong extending proximally away from the second junction along the X-axis in the positive x-direction and laterally away from the junction in the Y-axis in the negative y-direction, the second prong also including a distal flange that extends laterally toward the second junction in the Y-axis in the positive y-direction but does not overlap the second junction;
- wherein the distal flange of the first prong extends toward the distal flange of the second prong.
2 more elements
A surgical forceps comprising:
- a first leg repositionable with respect to a second leg, the first leg having mounted thereto a first hook, the first hook including a convex exterior portion and a concave interior portion, the concave interior portion of the first hook partially defining an internal cavity, the second leg having mounted thereto a second hook, the second hook including a convex exterior portion and a concave interior portion, the concave interior portion of the second hook partially defining the internal cavity, wherein the concave interior portions of the first and second hooks face one another.
