Description

Folder Type Suture Suture Anchor

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an all-suture anchor, and more particularly, to a folder type suture anchor for re-establishing soft tissues such as ligaments, tendons, and articular capsules in bone.

Ligaments are elastic fibrous connective tissue that has elasticity and is primarily located in joints and connects bones with bones. The ligaments also stabilize or limit the motion of the joints by tightly resisting the movements of the joints, which makes them liable to damage.

Ligament injuries include sprains, torsion, tearing, and tearing. Ligament breakage occurs mainly at the site where the ligaments and bones are joined. Therefore, most of the surgery to reseal the broken ligament is in the form of fixing the ligament to the bone.

In the traditional way of securing the ligaments to the bones, the sutures are first screwed to the bone, the site of attachment, and the sutures are tied to the broken ligaments. Then, the sutures bound to the ligaments are fixed to the bone using a suture anchor. In Korean Patent Laid-Open Publication No. 10-2016-0131044 (name of the invention: 2-part seamless knot suture anchor) or Korean Patent Publication No. 10-2015-0007068 (name of the invention: suture anchor), etc. It introduces.

Suture anchor in traditional tradition as described above has the advantage of having a relatively strong fixing force. However, in the process of placing the anchor in the bone does not overcome the disadvantage of damaging the bone. Accordingly, an all-suture anchor has been developed that is somewhat weak in fixation but can reduce bone damage.

Pre-sealed anchors use woven sutures, which generally consist of a thick suture (straight or braided or hollow fiber) portion and a thin suture portion connected thereto.

Examining the process of the anchor suture anchor, a small small hole is drilled in the deposition site such as bone, and a thick suture located at the end of the suture thread is inserted into the hole at the deposition site. Subsequently, when the thin suture is pulled, the thick suture is condensed, that is, the volume is increased while being folded and fixed to the deposition site.

The type of thick suture for fixing used in electric suture anchors is direct irradiation (knot), knitting yarn or hollow fiber.

The mechanism of action depends on the various types of coarse sutures used in the electric suture anchor and the condensation method of each coarse suture.

The form of direct irradiation has a disadvantage of being difficult and difficult to manufacture because we make the required shape while weaving the yarn in the manufacturing process.

Hollow fiber shape is easy to manufacture, but there is a disadvantage that the outer edge of the hollow yarns are not condensed efficiently during condensation.

On the other hand, the knitting type has an advantage that the area is large, so that the condensation efficiency is excellent and the manufacturing is easy. However, the conventional knitting type has a disadvantage in that the fixing force is somewhat reduced because the anchor portion formed by condensation is formed due to the thin thickness but the thickness is large.

As described above, various types of fixing thick sutures used in the conventional electric suture anchor have various advantages and disadvantages. Therefore, there is a need for a form that can improve the condensation efficiency by supplementing the disadvantages of the conventional.

An object of the present invention has been made in view of the above points, and in particular, to provide a folder-type electric suture anchor that can further increase the fixing force for the electric suture anchor of the knitting type with good condensation efficiency.

The second suture hole 21, the fourth suture hole 23, the sixth suture hole 25, and the eighth suture hole 27 are formed in the second knitting portion 12. will be. The number of suture holes may be appropriately increased or decreased depending on the length of the knitting anchor, and is not limited only to the example shown in FIG. 2.

As shown in FIG. 2, in the longitudinal section of the knitting anchor 10, the (2n-1) suture holes 20, 22, 24, and 26 of the first knitting portion 11 and the second knitting portion ( The second n suture holes 21, 23, 25, and 27 of 12) are disposed at equal intervals in the longitudinal direction.

However, as shown in Fig. 3, in the cross section in the width direction of the knitting anchor 10, the (2n-1) suture holes 20, 22, 24, 26 and the second knitting yarn of the first knitting portion 11 are shown. The second n suture holes 21, 23, 25, 27 of the portion 12 are staggered from one another in the longitudinal direction, respectively. That is, when the first knitting portion 11 and the second knitting portion 12 are stacked as the suture 30 is pulled, the (2n-1) suture holes 20, 22, 24, 26 and 2n suture holes 21, 23, 25, and 27 are staggered, respectively.

The suture 30 includes second (2n-1) suture holes 20, 22, 24, and 26 formed in the first knitting portion 11 and second n suture holes 21, 23 formed in the second knitting portion 12. 25 and 27 are alternately penetrated. Specifically, the suture 30 is fitted in the width direction between the (2n-1) suture holes 20, 22, 24, 26 and the 2n suture holes 21, 23, 25, 27, and the (2n-) suture 30. 1) between the suture holes 20, 22, 24, 26 or between the second n suture holes 21, 23, 25, 27

That is, as shown in Figures 4 to 6, the suture 30 is fitted in the width direction on one surface of the knitting anchor 10, and is inserted in the longitudinal direction on the other surface of the knitting anchor 10. 5 shows the shape of the outer side in which the suture 30 is fitted, and FIG. 6 shows the shape of the inner side in which the suture 30 is fitted. Here, the outer and inner sides are determined when the first knitting portion 11 and the second knitting portion 12 are stacked as the suture 30 is pulled.

As shown in FIGS. 4 to 6, when the suture 30 is pulled in the state in which the suture 30 is fitted, the knitting anchor 10 overlaps the first knitting portion 11 and the second knitting portion 12. It is folded in the width direction while being folded in the longitudinal direction. In particular, the fold in the width direction is suture thread as the (2n-1) suture holes (20, 22, 24, 26) and the 2n suture holes (21, 23, 25, 27) are alternately arranged in the longitudinal direction, respectively, Pulling (30) will fold by the force to get closer to each other.

Next, the structure in which the suture 30 is fitted is detailed.

The suture 30 penetrates the first suture hole 20 provided in the first knitting portion 11 and passes through the second suture hole 21 provided in the second knitting portion 12 in the width direction. After fitting, the second suture hole 21 passes through the fourth suture hole 23 provided in the second knitting portion 12 and is inserted in the longitudinal direction.

Subsequently, after passing through the fourth suture hole 23, the third suture hole 22 provided in the first knitting portion 11 is inserted in the width direction, and then passes through the third suture hole 22. Through the fifth suture hole 24 provided in the first knitting portion 11 is fitted in the longitudinal direction.

Subsequently, after penetrating the fifth suture hole 24, the penetrating width is penetrated through the sixth suture hole 25 provided in the second knitting portion 12, and penetrates the sixth suture hole 25. It penetrates in the longitudinal direction through the eighth suture hole 27 provided in the second knitting portion 12.

Subsequently, after penetrating the eighth suture hole 27, the penetrally fits in the width direction through the seventh suture hole 26 provided in the first knitting portion 11.

As such, when the suture 30 is inserted into the suture holes 20 to 27 and the suture 30 is pulled, the external force P transmitted from the placement mechanism is applied in the direction shown, the knitting anchor 10 is placed. It is folded in the width direction and the length direction in the hole provided for. As the suture 30 is pulled, the knitting anchor 10 is folded, that is, the volume increases while condensing and is fixed to the deposition site. When the knitting anchor 10 is folded, the condensation in the longitudinal direction and the condensation in the width direction occur at the same time, and the volume of the condensed portion is further increased by the heat-adhesive portions provided at both ends. This increases.

Suture 30 may be formed to have a hollow as shown in Figure 7 by weaving two or more yarns in a tubular shape.

In addition, the suture 30 may have a band formed at regular intervals to measure the depth of implantation of the knitting anchor 10. The bands formed on the suture 30 may be formed in different colors, or may be formed in the same color.

When the bands formed in the suture 30 are formed in different colors, they may have different depths depending on the colors. For example, the practitioner may recognize to what extent the knitting anchor 10 is being implanted by checking the band color of the suture 30 exposed to the outside of the hole in the process of placing the knitting anchor 10 into the hole. Can be.

When the bands formed in the suture 30 are formed in the same color, the length of the interval at which the bands of the suture 30 are formed is determined to be constant. Accordingly, the operator checks how many bands of the suture 30 are inserted into the hole in the process of placing the knitting anchor 10 into the hole to determine how deep the knitting anchor 10 is placed. It can be recognized.

Knitting anchor 10 may be formed by weaving a thread of the same material as the suture 30 is sewn on it.

Alternatively, the knitting anchor 10 may be formed by weaving a thread of a different material from the suture 30 sewn therein, and the knitting anchor 10 is preferably formed by being woven with an absorbent yarn absorbed by a human body over time. .

Suture 30 may also be used both absorbent and non-absorbent, so the selection of material may be easily applied according to the design.

While the preferred embodiments of the present invention have been described so far, those skilled in the art may implement the present invention in a modified form without departing from the essential characteristics of the present invention.

Therefore, the embodiments of the present invention described herein are to be considered in descriptive sense only and not for purposes of limitation, and the scope of the present invention is shown in the appended claims rather than the foregoing description, and all differences within the scope are equivalent to the present invention. Should be interpreted as being included in.
