Suture based clamping device
Systems, assemblies, and methods are provided herein for fastening of one bone to another bone using one or more sutures. The features herein enable such fastening with a more accurate strength, and which can be more easily fastened in-situ.
1 . A suture-button system comprising:
(a) a plurality of suture strands;
(b) a primary button having a plurality of primary apertures, wherein:
(i) a first suture strand of the plurality of suture strands is inserted through a first set of primary apertures of the plurality of primary apertures;
(ii) a second suture strand of the plurality of suture strands is inserted through a second set of primary apertures of the plurality of primary apertures;
(iii) the plurality of primary apertures comprises at least eight primary apertures;
(iv) the first set of primary apertures is different from the second set of primary apertures;
(v) the first set of primary apertures are equally spaced relative to each other in a least a partially circular array; and
(vi) one or both of the first suture strand and the second suture strand is inserted through the respective first set of primary apertures and second set of primary apertures in a weaving configuration; and
(c) a secondary button having a plurality of secondary apertures, wherein:
(i) the first suture strand and the second suture strand are each inserted through a first and second secondary aperture of the plurality of secondary apertures, wherein the suture-button system is configured to clamp at least one targeted tissue of a subject between a distal surface of the primary button and a proximal surface of the secondary button upon application of a tension to one or both of the first suture strand and the second suture strand.
2 . The suture-button system of claim 1 , wherein the first set of primary apertures and the second set of primary apertures are disposed symmetrical to each other on the primary button.
3 . The suture-button system of claim 1 , wherein the primary button comprises a primary threaded portion for receiving a secondary threaded portion of a lock, so as to removably couple the lock to the primary button, such that one or both of the first suture strand and the second suture strand are prevented from translating through the respective primary apertures and thereby securing the clamping of the targeted tissue.
4 . The suture-button system of claim 3 , wherein the primary threaded portion comprises a female threaded portion.
5 . The suture-button system of claim 3 , wherein the lock comprises a head and wherein the secondary threaded portion extends from the head.
6 . The suture-button system of claim 5 , wherein a distal surface of the head is tapered outwards from a center axis of the lock.
7 . The suture-button system of claim 3 , wherein the lock comprises a driver feature, an alignment feature, or both.
8 . The suture-button system of claim 7 , wherein the driver feature and the alignment feature are generally concentric.
9 . The suture-button system of claim 1 , wherein a distal surface of the secondary button comprises a channel connecting two or more of the plurality of secondary apertures.
