Abstract
A multi-staple inserter and drill guide, and methods of use thereof, are disclosed therein. The orthopedic staples can also be used in addition to interfragmentary screws to apply further compression of the bone fragments.
Claims20
An insertion system comprising:
- a body including a first side and an opposing second side, wherein a first staple includes a first bridge and a first pair of legs each attached to the first bridge at a first elastic hinge region and a second staple including a second bridge and a second pair of legs each attached to the second bridge at a second elastic hinge region, wherein the first staple and the second staple are mounted to the body, and the first staple and the second staple are identical and comprise Nitinol;
- a first pair of plates each mounted to the first side of the body by a first proximal pin and a second pair of plates each mounted to the second side of the body by a second proximal pin, wherein each of the first pair of plates includes a first distal pin and each of the second pair of plates includes a second distal pin, and the first staple is mounted on the first distal pins and the second staple is mounted on the second distal pins, each of the first distal pins of the first pair of plates are located under one of the first elastic hinge regions of the first staple, and each of the second distal pins of the second pair of plates are located under one of the second elastic hinge regions of the second staple;
- a handle moveable in a first direction and an opposing second direction;
- a plunger having a proximal end and a distal end, wherein movement of the handle causes the distal end of the plunger to push against a bending structure;
- and
- the bending structure capable of engaging the first bridge and the second bridge, wherein rotation of the handle in the first direction causes the bending structure to engage and bend the first bridge and the second bridge simultaneously to configure the first staple and the second staple from an unrestrained state in which the first pair of legs and the second pair of legs are angled inwardly to a strained state in which the first pair of legs and the second pair of legs are substantially perpendicular to the bridge, and rotation of the handle in the opposing second direction causes the threaded rod and the plunger to move proximally and the bending structure removes pressure from the first bridge and the second bridge.

An insertion system comprising:
- a body, wherein a first staple includes a first bridge and a first pair of legs each attached to the first bridge at a first elastic hinge region and a second staple that includes a second bridge and a second pair of legs each attached to the second bridge at a second elastic hinge region, and the first staple and the second staple are mounted to the body;
- a bending structure capable of bending the first bridge and the second bridge, wherein the bending structure bends the first bridge and the second bridge to configure the first staple and the second staple from an unrestrained state in which the first pair of legs and the second pair of legs are angled inwardly to a strained state in which the first pair of legs and the second pair of legs are substantially perpendicular to the bridge.
A method of inserting at least two staples into a bone comprising:
- moving a handle of a multi-staple inserter of an insertion system in a first direction to configure the at least two staples mounted to a body of the multi-staple inserter from an unrestrained state to a strained state to bend a bridge of the at least two staples to move a pair of legs of the at least two staples to be substantially perpendicular to the bridge;
- inserting each of the pair of legs of the at least two staples into a set of holes in the bone;
- and
- releasing the at least two staples from the body of the multi-staple inserter.
