Abstract
The present invention relates to a clip system for ligament reconstruction, comprising a clip comprising portions forming a loop-like closed structure extending in two directions, suitable for being placed in a hole drilled in a bone, and a button-like counterpart.
Claims18
A clip for ligament reconstruction, comprising at least eight portions, wherein
- each portion has independently a cross-section having a form of a rectangle or an ellipse, wherein the largest dimension of the cross-section is from 0.5 to 3 mm,
- each portion has a first end and a second end, a distance between the first end and the second end defining a length of the portion, and
- the portions being
- a first portion defining a first plane, its length being from 4 to 10 mm,
- a second portion attached by its first end to the second end of the first portion, essentially perpendicular to the first portion, in the first plane, its length being from 6 to 14 mm,
- a third portion attached by its first end to the second end of the second portion, essentially perpendicular to the second portion and parallel to the first portion, in the first plane, extending from the second portion in a direction parallel to the direction from the second end of the first portion towards the first end of the first portion, its length being from 10 to 24 mm,
- a fourth portion attached by its first end to the second end of the third portion, essentially perpendicular to the third portion and parallel to the second portion, in the first plane, extending from the third portion in a direction parallel to the direction from the second end of the second portion towards the first end of the second portion, its length being essentially identical to the length of the second portion,
- a fifth portion attached by its first end to the second end of the fourth portion, essentially perpendicular to the fourth portion and aligned with the first portion, in the first plane, extending from the fourth portion towards the first portion, its length being from 4 to 10 mm,
- a sixth portion attached by its first end to the second end of the fifth portion, essentially perpendicular to the fifth portion, in a second plane that is perpendicular to the first plane, its length being from 4 to 8 mm,
- a seventh portion attached by its first end to the second end of the sixth portion, essentially perpendicular to the sixth portion and parallel to the first portion, in the second plane, extending from the sixth portion in a direction parallel to the direction from the first end of the first portion towards the second end of the first portion, its length being from 2 to 7 mm, and
- an eighth portion attached by its first end to the second end of the seventh portion and by its second end to the first end of the first portion, essentially perpendicular to the seventh portion and the first portion and parallel to the sixth portion, in the second plane, its length being essentially identical to the length of the sixth portion;
- wherein the first portion, the second portion, the third portion, the fourth portion and the fifth portion form a stadium like form factor, wherein an inner radius in a corner defined by an attachment point between the portions is from 1 to 3 mm and an outer radius of the corners is from 2 to 6 mm.
