BEST MODE

(17) Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1A to 3C. The embodiment described below will be described to help provide more comprehensive understanding of the present invention, and those skilled in the art will appreciate that the present invention can be embodied in many alternate forms different from the embodiment of the present invention. In the following description, a detailed description of known functions and components incorporated herein will be omitted when it may make the subject matter of the present invention unclear. In addition, the shapes, sizes, etc. of components in the accompanying drawings may be exaggerated to make the description clearer.

(18) The present invention relates to a method of preparing a suture anchor using a suture in a special preparation way and to a suture anchor with a special structure prepared by the method. First, a first biologically compatibility suture 10 that has been widely used in the human body is knitted in the special way to form a plurality of knots 10a. Next, the knitted suture is cut at a predetermined length to form a knitting member 100 having a predetermined width and the predetermined length. Finally, a second suture 20 is provided between one knot 10a of the plurality of knots and another knot 10a thereof by sewing in a longitudinal direction of the knitting member 100, the second suture 20 being capable of attaching a soft tissue such as a damaged joint membrane, a cartilage, a muscle, or a ligament to a bone by sewing.

(19) The embodiment of the present invention for the method of preparing the suture anchor using a suture will be described.

(20) According to the embodiment of the present invention, the method of preparing the suture anchor using a suture is configured such that the first suture 10 having biological compatibility for use in the human body is provided as two rows of sutures constituting a pair, and the first sutures 10 are bent in a “U”-shape, as shown in FIG. 1A.

(21) An open space portion b is formed at the front of the “U”-shape and a loop space portion a connected thereto is formed at the rear thereof by crossing a first end 11 of the pair of the first sutures 10 and a second end 12 thereof into an “X”-shape, as shown in FIG. 1B. Then, using a tool such as a finger or a knitting needle, the first end 11 is pulled out rearwards by passing the tool through the loop space portion a and inserting the tool into a lower side of the open space portion b from a lower side of the “X”-shape to hook a portion of the first end 11 as shown in FIG. 1C. As shown in FIG. 1D, a first knot 10a is formed by further pulling the hooked portion of the first end 11 rearwards, in a state of passing through the inside of the loop space portion a as shown in FIG. 1C.

(22) After the knot 10a is formed as FIG. 1D, the plurality of knots 10a is formed in a long line as shown in FIG. 1E by repeating several times the process of forming the knot 10a. The process is configured by passing the tool such as the finger or the knitting needle through the loop space portion a, inserting the tool from the lower side of the “X”-shape into the lower side of the open space portion b to hook the first end 11, and passing again the hooked portion of the first end 11 through the inside of the loop space portion a and further pulling the portion. Then, the knitting member 100 having the predetermined length is formed by cutting the plurality of knots at the predetermined length and by bonding the cut portion so that the cut portion is not untied, as shown in FIG. 1F.

(23) After the knitting member 100 is formed, as shown in FIG. 2A, a predetermined number of second sutures 20 are provided between one knot 10a and the other knot 10a of the knots by sewing in the longitudinal direction of the knitting member 100, the second suture 20 being capable of attaching the soft tissue such as the damaged joint membrane, the cartilage, the muscle, or the ligament to the bone by sewing.

(24) According to the present invention, the suture anchor prepared by the method uses the suture having biological compatibility for use in the human body, so that the suture anchor of the present invention has excellent compatibility. In addition, the knitting member is cut to have a predetermined width and a predetermined length and the cut portion is bonded at the same time, so that the cut portion is not untied.

(25) The predetermined number of second sutures 20 capable of attaching the soft tissue such as the damaged joint membrane, the cartilage, the muscle, or the ligament to the bone by sewing is provided between one knot 10a and the other knot 10a of the knots by sewing in longitudinal the direction of the knitting member 100. Thus, unlike most conventional anchors, that is, anchors made of metallic materials, or absorbable or non-absorbable polymer materials, the suture anchor of the present invention is provided with the special structure configured to deform a shape of the knitting member 100.

(26) Hereinafter, a method of using the suture anchor of the present invention will be described.

(27) In order to use the suture anchor according to the embodiment of the present invention, first, on a portion to be operated, a hole 1a is bored on a bone 1 using a boring device (not shown) as shown in FIGS. 2B to 2C. Next, a middle portion of the knitting member 100 making the suture anchor is put in a groove provided in a front end of an anchor inserting device 200, and to make easy insertion of the knitting member 100, the knitting member 100 in a bent state of the “U”-shape is positioned above the hole 1a provided in the bone 1, as shown in FIG. 3A.

(28) Then, the knitting member 100 is inserted deep into the bone 1 through the hole 1a of the bone 1, as shown in FIG. 3B.

(29) In the state of FIG. 3B, the groove provided in the front end of the anchor inserting device 200 is pulled back. More preferably, as shown in FIG. 3C, after closing an opening of the hole 1a of the bone 1, opposite ends of the second sutures 20 are pulled rearwards, the second sutures being connected to the knitting member 100 by sewing the predetermined number of the second sutures in the longitudinal direction of the knitting member 100. Then, as the opposite ends of the knitting member 100 are compressed, the entire knitting member 100 is gradually deformed from a long rod shape into a lump shape, and a volume of the lump is increased more than a diameter of the hole 1a of the bone 1, so that the knitting member 100 deformed into the lump shape cannot be removed from the hole 1a of the bone 1 even when the second sutures 20 are pulled rearwards.

(30) Accordingly, the second sutures 20 are used to sew the soft tissue such as the damaged joint membrane, the cartilage, the muscle, or the ligament to the bone, and are pulled with a predetermined strength to attach the tissue close to the bone 1.

(31) The suture anchor according to the embodiment of the present invention is prepared in the following special way: the first sutures 10 having biological compatibility for use in the human body are knitted in the special way to form the plurality of knots 10a; the plurality of knots 10a is cut at the predetermined length to form the knitting member 100 having the predetermined width and length; and the other sutures that can attach the soft tissue such as the damaged joint membrane, the cartilage, the muscle, or the ligament to the bone by sewing, that is, the second sutures 20, are provided between the knots in the longitudinal direction of the knitting member 100. In addition, the knitting member 100 is deformed from the long rod shape into the lump shape, so that the suture anchor of the present invention is firmly fixed in the hole 1a of the bone 1 so that it is not removed therefrom, and has relatively large fixation strength when the soft tissue is pulled during sewing.

(32) Accordingly, when a recovery size (area) of a damaged portion is large, a surgery using the suture anchor of the present invention does not require the use of a plurality of anchors that provides appropriate fixation strength needed to proper attach the soft tissue such as the damaged joint membrane, the cartilage, the muscle, or the ligament to the bone 1, so that the surgery can be performed easily and quickly.

(33) In addition, when the recovery size (area) of the damaged portion is large, conventionally, since most anchors are anchors made of the metallic materials, or the absorbable or non-absorbable polymer materials, the number and positions of anchoring points may be restricted due to a size of the plurality of anchors. However, the use of the suture anchor of the present invention has few restrictions on the number and positions of the anchoring points.

(34) In addition, according to the present invention, it is unnecessary to perforate a plurality of holes 1a in the bone 1 in comparison with the related art, so that tissue recovery can be performed quickly without affecting the soft tissue and the bone.

INDUSTRIAL APPLICABILITY

(35) According to the embodiment of the present invention, the suture anchor using a suture can be used for suturing a soft tissue such as a damaged joint membrane, a cartilage, a muscle, a ligament, or the like.
