Technical Field

[0004] The present invention relates generally to suture anchors, and more specifically to knotless suture anchor constructions for securing tissue relative to bone holes in a desired position. Background Technology

[0005] Surgical procedures typically require a suture anchor to provide a reliable attachment location for sutures in the base and / or against the base. The attached suture is then used to capture and retain other objects, including soft tissue. The base can be bone or bone material or soft tissue. For bone and osteoid materials, the suture anchor can be inserted into a pre-formed hole in the bone, such that the attached suture extends from the suture anchor out of the pre-formed hole. In the case of a soft tissue base, the suture anchor can reside on the soft tissue side, such that the suture extends from the suture anchor through a hole in the tissue and further extends beyond the soft tissue on the side opposite the soft anchor.

[0006] In conventional practice, suture anchors incorporate at least one feature to generate retention capability, holding the anchor within a pre-formed hole. In some anchors, this feature embodies a ridge member that deforms to create an interference fit with the substrate. Other suture anchors utilize external features (e.g., barbs, threads, etc.). These external features typically interact with the substrate to generate retention capability by piercing, cutting, and / or deforming it. In other suture anchors, this feature may be movable (e.g., a deployable barb) that translates to generate retention capability.

[0007] Many factors can directly influence the actual retention capability achieved by any suture anchor. For example, depending on the design of a particular suture anchor, the quality of bone or soft tissue can significantly increase or decrease retention capability. Therefore, some suture anchors perform well in certain situations, while others perform better in others. Similarly, the quality of installation also affects retention capability.

[0008] Therefore, a suture material is needed that is inserted into a soft, stretchable substrate to form a loop configuration, so as to pull the repair suture into the pre-formed hole and deform the substrate.

Summary of the Invention

[0010] This invention relates to a knotless suture anchor construction, which is optimal for securing tissue relative to a bone hole in a desired location. According to one aspect, the knotless suture anchor construction includes a base having a first end and a second end, and filaments woven along the base through a plurality of pass-through locations. The filaments form a first loop extending to a through branch and a reduction branch. A through portion is present in the reduction branch between two adjacent pass-through locations among the plurality of pass-through locations. In a pre-deployment configuration, the first loop of the filament extends from the first end of the base, and the through branch and reduction branch extend from the second end of the base. Similarly, in the pre-deployment configuration, the through portion extends through the first loop, thereby forming a second loop in the reduction branch.

[0011] According to another aspect, the knotless anchor construction includes a filament having a joint between a through branch and a reduction branch. The through branch extends through the joint, thereby forming a first loop. The construction also includes a base having a first end and a second end. In the pre-deployment configuration, the filament is woven through the base such that the through branch extends through a first through position on the first end of the base, and the reduction branch extends through one or more through positions toward the second end of the base. A through portion exists in the reduction branch between two adjacent through positions among these one or more through positions toward the second end of the base. In the pre-deployment configuration, the through portion extends through the first loop, thereby forming a second loop in the reduction branch.

[0012] According to another aspect, the present invention is a method for securing an object in place relative to a bone hole. The method includes the following steps: (i) providing a knotless suture anchor construction comprising a base having a first end and a second end, filaments woven along the base through a plurality of pass-through locations forming a first loop extending to a through branch and a reduction branch, wherein the first loop of the filament extends from a first end of the base, and the through branch and reduction branch extend from a second end of the base, and a through portion in a reduction branch between two adjacent through locations, wherein the through portion extends through the first loop, thereby forming a second loop in the reduction branch; (ii) inserting the knotless suture anchor construction into a bone hole; (iii) causing the through branch to extend around the object and then through the second loop; and (iv) tensioning the reduction branch to reduce the size of the second loop.

[0013] These and other aspects of the invention will become apparent and will be elucidated with reference to the embodiments described below.

[0014] The following discussion describes embodiments of a suture anchor configured to pull a repair suture into a pre-formed hole in bone or bone tissue. These configurations may have filaments (e.g., sutures) interwoven into a soft, stretchable substrate (e.g., a suture band). The interwoven filaments can form loops to receive the free ends of the repair sutures originating from a fixation site adjacent to the pre-formed hole. In use, tension on the free ends of the interwoven filaments causes the loops to translate and engage the repair suture, thereby effectively pulling the free ends into the pre-formed hole and interweaving the repair suture with the substrate to allow the filaments to translate freely across the substrate relative to the repair suture.

[0040] The invention, along with certain features, advantages, and details thereof, is explained more fully below with reference to the non-limiting examples shown in the accompanying drawings. Descriptions of well-known structures have been omitted to avoid unnecessarily obscuring the invention in detail. However, it should be understood that the detailed descriptions and specific non-limiting examples, while indicating aspects of the invention, are given by way of illustration only and not by way of limitation. Various substitutions, modifications, additions, and / or arrangements within the spirit and / or scope of the basic concept of the invention will be apparent to those skilled in the art based on this disclosure.

[0041] Now refer to the accompanying drawings, in which similar reference numerals always refer to similar parts. Figure 1 A top view schematic diagram of a knotless suture anchor construction 100 in a planar configuration according to one embodiment is shown. The knotless suture anchor construction 100 includes a base 102 having a first end 104 and a second end 106 and extending between the first and second ends along a central longitudinal y-axis. The base 102 can be any suture material, such as a Y-knot. Suture tape. In the depicted embodiment, the base 102 is rectangular, although other shapes and configurations may be used.

[0042] The knotless stitch anchor 100 also includes a first filament 108 woven through the substrate 102. The filament 108 can be composed of any stitching material. In a preferred embodiment, the filament 108 is composed of a hollow stitch braid that is flattened and does not flip like a circular stitch (but can be circular, flat, and / or include or exclude a core). In a first configuration, the filament 108 is folded at a central portion 110 (“central portion” herein is interpreted as any folded area of ​​the filament 108, not necessarily the middle of the filament 108), thereby forming a through branch 112 and a reduction branch 114. The filament 108 is woven through the substrate 102 from a first surface 116 to a second surface (not shown) at a plurality of through locations 118. In the depicted embodiment, the filament 108 is woven such that the central portion 110 extends from a first end on a first end 104 of the substrate 102 through location 118A, thereby forming a first loop 120 (having a first diameter) in the filament 108.

[0043] Similarly, Figure 1 As shown, the weave extends along the base 102 toward the second end 106 via additional pass position 118 through branch 112 and reduction branch 114. Branch 112 and reduction branch 114 extend from the second end at the second end 106 of the base 102 via position 118B. Therefore, in a planar configuration, as... Figure 1 As shown, the first loop 120 of the filament 108 extends from the first end 104 of the substrate 102 and extends from the second end 106 of the substrate 102 through the branch 112 and the reduction branch 114.

[0044] Now go to Figure 2 The figure shows a top view of a knotless seamless anchor structure 100 with a second ring 122 according to one embodiment. In the planar configuration of the knotless seamless anchor structure 100, the through portion 124 of the reduced branch 114 between two adjacent central through positions 118C, 118D is pulled away from the central longitudinal y-axis from the base 102. As shown, when the through portion 124 is pulled away from the base 102, a second ring 122 (having a first diameter) is formed in the reduced branch 114.

[0045] Now for reference Figure 3 and Figure 4 The diagram shows a top view of a knotless anchor construction 100 according to one embodiment, wherein a second ring 122 passes through a first ring 120. At the reduction branch 114 ( Figure 2 After the second ring 122 is formed in the substrate 102, the second ring 122 passes through the first ring 120 at the first end 104 of the substrate 102, as shown. Figure 3As shown. Then, the first ring 120 is tensioned by pulling along the second end 106 away from the base 102 through the branch 112. Tensioning through the branch 112 reduces the size of the first ring 120 to a second diameter smaller than the first diameter. As... Figure 4 As shown, when the size of the first ring 120 decreases, it surrounds or contracts around the second ring 122, thereby moving the knotless anchor structure 100 to the pre-deployment configuration.

[0046] Now go to Figure 5 and Figure 6 The diagram shows a perspective view and a side view of a knotless anchor structure 100 used around an object 126 according to one embodiment. In the pre-deployment configuration, as shown... Figure 4 As shown, the knotless suture anchor structure 100 is inserted into the bone hole 121 ( Figure 6 In ) . For example Figures 5 to 6 As shown, the knotless suture anchor structure 100 is positioned at the bone hole 121 of an adjacent object 126, such as tissue. Figure 6 In this context, although object 126 can be any other biological material, exemplary embodiments in which object 126 is an tissue are discussed below. Figure 5 As shown, the knotless suture anchor construction 100 is positioned such that the first end 104 of the base 102 is proximal to the tissue 126, while the second end 106 of the base 102 is distal. Alternatively, as Figure 6 As shown, the knotless suture anchor structure 100 can be placed in the bone hole 121 below the tissue 126, such that the first end 104 of the base 102 extends toward one side of the tissue 126 and the second end 106 of the base 102 extends toward the opposite side of the tissue.

[0047] With the second ring 122 positioned adjacent to the tissue 126, a knotless suture anchor structure 100 can be deployed. To deploy the knotless suture anchor structure 100, first pass through the second ring 122 via the branch 112, then through or around the tissue 126, as follows: Figure 5 and Figure 6 As shown. Therefore, the tissue 126 is grasped by wrapping around or otherwise through the branch 112 and the second loop 122. After wrapping around (or through) the tissue 126 through the branch 112, the tissue is returned through the branch 112 and the second loop 122, as shown. Figure 5 and 6 As shown.

[0048] Now for reference Figures 7 to 9A perspective and side view of a knotless suture anchor structure 100 used around tissue 126 according to one embodiment are shown. After the through branch 112 returns through the second loop 122, the reducing branch 114 is tensioned. By pulling the reducing branch 114 in a direction away from the base 102, the first diameter of the second loop 122 decreases to a second diameter. In other words, when the reducing branch 114 is tensioned, the second loop 122 begins to tighten around the through branch 112, as... Figures 8 to 9 As shown.

[0049] Now for reference Figures 10 to 11 The diagram shows a perspective and side view of a knotless suture anchor construction 100 in a deployment configuration according to one embodiment. In the deployment configuration, the reduction branch 114 has been tensioned such that the second ring 122 is tightened around the through branch 112 extending therethrough. Due to the reduced size of the second ring 122, tissue 126 is drawn closer to or near the base 102 (and bone foramen 121, as shown). Figure 11 (as shown), thereby placing the knotless suture anchor structure 100 relative to the tissue 126 in the desired position.

[0050] Now go to Figure 12 and Figure 13 The diagram shows a top view and a bottom view of a knotless seamless anchor structure 100 with a second filament 128 (hereinafter referred to as a "locking filament") according to an alternative embodiment. Figure 12 In the middle, the knotless anchor structure 100 is in the pre-deployment configuration (such as...). Figure 4 (As shown). With the knotless anchor construction 100 in its pre-deployment configuration, the locking filament 128 is woven through branches 112 and reduction branches 114 extending from the second surface 117 of the substrate 102, as shown. Figure 13 As shown. Locking filament 128 prevents tearing through the base 102 via branch 112 and reducing branch 114. Locking filament 128 also prevents the second loop 122 from being pulled across the base 102. Locking filament 128 can be composed of any type of thread, such as monofilament, braid, or stitch tape.

[0051] Still referencing Figure 13 The locking filament 128 passes through the through branch 112 and the reduction branch 114 between two adjacent through positions 118. In other words, the locking filament 128 may pass through one or more exposed portions of the through branch 112 and the reduction branch 114 on the second surface 117 of the substrate 102. Figure 13In the illustrated embodiment, the locking filament 128 is woven through the through branch 112 and the reduction branch 114 between three pairs of adjacent through positions 118, with each pair of adjacent through positions 118 crossing below the through branch 112 and the reduction branch 114 each time. In another embodiment, the locking filament may pass through the exposed portions of the through branch 112 and the reduction branch 114 on the first surface of the substrate 102.

[0052] Now for reference Figure 14 and Figure 15 The diagrams show perspective and side views of the knotless seamless anchor structure 100 in the pre-deployment and deployment configurations according to alternative embodiments. Figure 14 The knotless anchor construction 100 includes a base 102 and a filament 108. The filament 108 includes a first end 130 and a second end 132, with an eyelet 134 between them. The portion of the filament 108 between the first end 130 and the eyelet 134 includes a through branch 112, while the portion of the filament 108 between the second end 132 and the eyelet 134 includes a reduction branch 114.

[0053] In order to achieve Figure 14 The first configuration shown first forms a first loop 120 by passing through the eyelet 134 via branch 112. Then, branch 112 is woven through at least one through-position 118 at the first end 104 of the base 102. The weaving through branch 112 extends from the first end 104 of the base 102. A reduction branch 114 is woven through the base 102 toward the second end 106 of the base 102. Specifically, the reduction branch 114 is woven through through-position 118 adjacent to the through-position 118 of branch 112. In the depicted embodiment, as shown, the reduction branch 114 is woven along the base 102 through at least two through-positions 118 and extends from the second end 106 of the base 102.

[0054] Still referencing Figure 14 The through portion 124 of the reduced branch 114 between two adjacent through positions 118 is pulled out from the base 102. As the through portion 124 is pulled away from the base 102, a second ring 122 is formed in the reduced branch 114. To achieve the pre-deployment configuration, as shown, the second ring 122 passes through the first ring 120. Figure 15 As shown, for deployment, the knotless suture anchor structure 100 is placed in the bone hole 121 ( Figure 15 The desired position of an object 126, such as an organization, relative to the object 126.

[0055] exist Figure 14 In this configuration, the knotless suture anchor 100 is positioned such that the first end 104, passing through branch 112 and base 102, is proximal to tissue 126. (As shown) Figure 15 As shown, the tissue is then wound around or passed through the tissue via branch 112. Then, the tissue passes through the second loop 122 via branch 112. To reduce the size of the second loop 122 (from the first diameter to the second diameter), the reducing branch 114 is pulled away from the bone hole 121. When the reducing branch 114 is tensioned, the size of the second loop 122 decreases and tightens around the passing branch 112, thereby pulling the tissue 126 to a position juxtaposed with the bone hole 121. When the tissue 126 is in the desired position, the passing branch 112 and the reducing branch 114 can be trimmed.

[0056] Now turn to the diagram. (Refer to...) Figure 16 This figure shows a schematic side view of a knotless anchor construction 100 on a drive 200 according to one embodiment. In the depicted embodiment, a base 102 is placed within a forked end 202 of the drive 200. As shown, a first end 104 (and a second ring 122) of the base 102 is on a first side 204 of the drive 200. A second end 106 of the base 102 is on a second side 206 of the drive 200. Figure 16 As shown, a branch 112 and a reducing branch 114 extend from the second end 106 of the base 102 along the second side 206 of the actuator 200. In the depicted embodiment, a third filament 208 passes through the second loop 122. The third filament 208 can be pulled to elongate the second loop 122, while pulling the reducing branch 114 minimizes the second loop 122. Therefore, when the knotless suture anchor structure 100 is placed in the bone hole, the third filament 208 and the reducing branch 114 can be used to stabilize the second loop 122 and facilitate the deployment of the knotless suture anchor structure 100.

[0057] Now for reference Figures 17A to 20B Schematic diagrams of various views of the knotless anchor construction 100 of the alternative embodiment are shown. Figure 17A In the illustrated embodiment, the knotless anchor construction 100 includes a through portion 124 in the reduced branch 114, which wraps around the first loop 120 in a clockwise manner, rather than in... Figures 3 to 4 The implementation plan passes through the first ring 120. Figure 17B The knotless anchor structure 100 also has a through portion 124 for wrapping around the first ring 120, but its length is consistent with... Figure 17A Wrap the first loop 120 in the opposite direction (counterclockwise) as shown.

[0058] exist Figure 17C In the illustrated embodiment, portion 124 extends through the first ring 120; however, portion 124 extends from below (i.e., from the point where...) Figure 3 (in the opposite direction shown) passing through the first ring 120. In Figure 17DThe diagram illustrates an embodiment of a knotless anchor construction 100, wherein filaments 108 are woven through a base 102 along a first direction, a second direction, and back along the first direction. The filaments 108 pass through the base 102 to form a first loop 120 and extend from opposite sides of the base 102 via branches 112 and reduction branches 114.

[0059] exist Figure 18 In this configuration, the knotless anchor structure 100 includes an eyelet 134 within a first ring 120. A through portion 124 of a reduction branch 114 is wound around the first ring 120. Then, as shown, the reduction branch 114 is passed through the eyelet 134. Figure 19 In the middle, it extends from opposite sides of the base 102 via a branch (not shown) and a reduction branch 114. Furthermore, the knotless suture anchor construction 100 includes a "finger catcher" 135 on the reduction branch 114. A third filament 308 passes through the finger catcher 135 and the first loop 120, and grips the reduction branch 114. The third filament 308 is used to pull the reduction branch 114 and the first loop 120 through the finger catcher 135.

[0060] exist Figures 20A to 20B In the knotless anchor structure 100, a finger-shaped catcher 135 is included, through which a branch 112 and a tapering branch 114 pass. (As...) Figure 20A As shown, the through branch 112 and the tapering branch 114 extend from the finger trap 135 in the pre-deployment configuration. The knotless suture anchor construction 100 also includes an eyelet 134 in the through branch 112. The through branch 112 passes through the eyelet 134 to form a second ring 122. To deploy the knotless suture anchor construction 100, the through branch 112 passes through the first ring 120, around the object 126, and through the second ring 122, as shown. Figure 20B As shown. Tensioning the shrinking branch 114 reduces the size of the first ring 120 and moves the object 126 toward the finger trap 135.

[0061] Other configurations of the knotless seamless anchor construction 100 are conceivable, and it may include various elements such as finger catchers or eye connectors.
