CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application claims the benefit of United States Provisional Patent Application No. 63/226,451, filed on July 28, 2021, which is incorporated herein in its entirety.
BACKGROUND
[0002] The disclosure relates generally to orthopedic systems. More particularly, this disclosure relates to orthopedic systems for reducing fractures and openings in bone and other tissue in patients.
[0003] Broken bone and other tissue is often rejoined via staples and other devices. The probability of a broken bone healing properly is directly related to the degree to which the break site can be reapproximated, whether the break can be placed under compression and whether the break can be held under compression throughout the healing process via a device, such as one or more staples. As such, proper placement of one or more staples is critical for optimal healing. At times, more than one staple is desired to create the desired construct. However, adding more than one staple takes extra time and can be challenging to align the staples in a consistent or repeatable spacing.
SUMMARY
[0004] A multiple staple delivery device configured to deliver two or more staples via a release maneuver is disclosed. In at least one embodiment, the multiple staple delivery device can deliver two or more staples simultaneously. The multiple staple delivery device may position at least first and second staples adjacent each other to be positioned into a patient and released via a release maneuver. The numerous embodiments are configured to enable different release maneuvers to be used to release the staples. The release maneuver may be, but is not limited to being, lateral movement, rotary movement, movement of a retention member sufficient to permit release of both the first and second staples and lateral movement, removal of a restraint member, and the like.

In at least one embodiment, one or more of the first and second pins 20, 22 of the first pin set 18 and the first and second pins 28, 30 of the second pin set 26 may be aligned with each other. In at least one embodiment, all of the first and second pins 20,
22 of the first pin set 18 and the first and second pins 28, 30 of the second pin set 26 are aligned with each other. One or more of the first and second pins 20, 22 of the first pin set 18 and the first and second pins 28, 30 of the second pin set 26 may extend orthogonally from the first and second pin set support arms 24, 32, respectively. In at least one embodiment, all of the first and second pins 20, 22 of the first pin set 18 and the first and second pins 28, 30 of the second pin set 26 may extend orthogonally from the first and second pin set support arms 24, 32. One or more of the first and second pins 20, 22 of the first pin set 18 may extend from distal ends 44 of the first pin set support arms 24. One or more of the first and second pins 28, 30 of the second pin set 26 may extend from distal ends 46 of the second pin set support arms 32.
[0032] The lateral spacing 48 of the first and second pins 20, 22 of the first pin set 18 may be such to adequately support at least one staple 12, such as one or more first staples 14. In at least one embodiment, lateral spacing 48 of the first and second pins 20, 22 of the first pin set 18 may be such that the first and second pins 20, 22 support a staple 12 at first and second corners 50, 52, respectively, between legs 54, 56 and a bridge 58 of the staple 12. Similarly, lateral spacing 48 of the first and second pins 28, 30 of the second pin set 26 may be such to adequately support at least one staple 12, such as one or more second staples 16. In at least one embodiment, lateral spacing 48 of the first and second pins 28, 30 of the second pin set 26 may be such that the first and second pins 28, 30 support a staple 12 at first and second corners 50, 52, respectively, between legs 54, 56 and a bridge 58 of the staple 12.
