More specifically, the anchor body inserted into the bone through a fixing means for fixing the contact portion easily forms an omega shape To an omega note-type sleeve anchor that can be fixed within the bone.

Description

Omega knot type sleeve anchor

The present invention relates to a sleeve anchor that is inserted into a bone to secure soft tissue and bone using a suture.

In general, when a soft tissue such as tendon, ligament, or muscle is damaged (broken) or the soft tissue is broken, an operation method is used in which the soft tissue of the damaged part is attached and fixed to the bone.

For example, if a rotator cuff rupture is diagnosed due to an increase in sports or leisure population, the injured part is removed and the rotator cuff is fixed to the bone.

At this time, to fix the soft tissue such as a rotator cuff to the bone, the bone is punctured to insert an anchor, and the outer suture connected to the anchor is attached to the soft tissue so that the soft tissue can be attached and fixed to the bone.

The method of fixing the soft tissue to the bone by using the conventional suture S is disclosed in Korean Patent Laid-Open Nos. 2015-136707 and 2015-126855, in which a bolt- 1, a sleeve anchor 10 made of an elastic material is inserted into a bone B having an insertion hole B1 formed by an anchor insertion tool to form an omega And to induce them to have a shape.

Particularly, the method of using the sleeve anchor is simple because of its easy operation, and it is widely used because there is no complication to be imposed on the patient.

However, in order to make an omega shape inside the bone, such a procedure using a sleeve anchor should perform a preprocessing process in which the outer surface faces the ring before the sleeve anchor is inserted into the bone, If the both ends are not aligned horizontally, even if the sleeve anchor is inserted in the middle of the insertion into the bone, or if the insertion is made into the inside of the bone, it is difficult to fix the omega shape.

The present invention has been proposed in order to solve the above-mentioned problems. After the sleeve anchor is inserted into the bone through the anchor insertion tool, the anchor insertion tool is removed and the sleeve anchor easily maintains the omega shape inside the bone. So that the fixing force between the sleeve anchor and the bone can be increased.

According to an aspect of the present invention, there is provided an omega note-type sleeve anchor, which is formed in a columnar shape in which at least one suture thread is inserted and inserted, and is formed to have a ring shape by a contact portion, And an anchor body inserted into the anchor body and a fixing means fixed to the anchor body so as not to separate the anchor body from the anchor body and being fixed in the inside of the bone while maintaining an omega shape, Both ends of the anchor body are aligned with each other on a horizontal line, and are formed at positions adjacent to each other at a predetermined distance from both ends of the anchor body.

The fixing means may be made of an adhesive harmless to the human body, a wire made of the same or different material as the suture material, the wire being wound around the outer surface of the anchor body or sewing and fixing the contact portion, and a tubular band fixed to surround the outer surface of the anchor body Or the like.

Further, it is preferable that a length between the contact portion and both ends of the anchor body becomes longer as the diameter of the insertion hole formed in the trough increases.

According to the present invention, the anchor body inserted into the bone through the fixing means for fixing the contact portion differently from the conventional one can be easily fixed within the bone by maintaining the omega shape.

1 is a view showing a state in which a conventional sleeve anchor is inserted into a valley;
2 is a view showing an omega note-type sleeve anchor according to the present invention;
Fig. 3 is another embodiment of the omega note-type sleeve anchor fixing means according to the present invention. Fig.
4 shows another embodiment of the omega note type sleeve anchor through hole according to the present invention.

Hereinafter, an omega note-type sleeve anchor (hereinafter referred to as "anchor") according to the present invention will be described in detail with reference to the accompanying drawings.

2, the anchor 1 according to the present invention mainly includes an anchor body 100 and a fixing means 200. As shown in Fig.

More specifically, the anchor body 100 is inserted and fixed in the bone B (see FIG. 1) with the suture S inserted therethrough so that the soft tissue can be fixed to the bone by the suture S .

The anchor body 100 is formed of an elastic material such as a surface harmless to the human body or silicone and is inserted into the anchor insertion tool and is inserted into the inside of the bone, Are intertwined with each other in a three-dimensional manner so that they can be inserted into the space of the spongy bone.

At this time, the anchor body 100 is inserted through an insertion hole B1 (see FIG. 1) drilled from the outer surface of the bone to the inside of the sponge bone, and the contact portion 120 is fixed by the fixing means 200, It is preferable to insert it into the anchor insertion tool so as to have a shape.

In addition, the contact point 120 is located at a position where both ends 130 and 130 'of the anchor body 100 having a ring shape facing the outer surfaces of the anchor body 100 coincide with each other on a horizontal line (H / L) So that it can be formed at a position adjacent to a predetermined distance.

The length L of each of the contact portion 120 and the both ends 130 and 130 'of the anchor body 100 is set to be longer in the oval shape so as to be longer as the diameter of the insertion hole formed in the bone increases. So as to increase the fixation force.

That is, as mentioned in the background art, the anchor body 100 inserted into the bone B through the insertion hole B1 by being inserted into the anchor insertion tool is inserted into both ends 130 and 130 ' Are fused so as to have an Omega shape as a whole symmetrically with respect to each other near the insertion hole, and fixed inside the bone.

Therefore, as the diameter of the insertion hole increases, the length L between the contact portion 120 and both ends 130 and 130 'of the anchor body 100 is made longer to secure a length at which the anchor body 100 can be opened .

In addition, a plurality of through holes 110 are formed in the outer surface of the anchor body 100 so as to communicate with the hollow portion so that the suture S can be inserted from the outside of the anchor body 100 through the inside thereof.

The suture S inserted through the through hole 110 through the anchor body 100 may be inserted through a plurality of sutures S per one through hole 110 to fix the soft tissue to the suture have.

Also, the fixing means 200 is configured so that the anchor body 100 can be easily fixed within the bone when the anchor body 100 inserted into the bone through the insertion hole is separated from the anchor insertion tool.

At this time, the fixing means 200 is made of a material harmless to the human body, but it is possible to use the same or different material as the adhesive and the suture S for adhering and fixing the contact portions 120, It is preferable to use at least one of a wire for preventing separation of the winding contact portion 120 and a tubular band inserted into the anchor body 100 facing each other. An example is given as an example.

The bands, which are one of the fixing means 200, are generally open on both sides and have a hollow tube shape, and are inserted and fixed to cover the entire anchoring body 100 facing each other, thereby preventing the contact portion 120 from being separated.

At this time, the outer diameter of the band having the tubular shape is formed to be smaller than the inner diameter of the insertion hole, so that the insertion of the anchor body 100 having the ring shape is facilitated, and the fixing of the band inserted through the outer surface of the anchor body 100, It is preferable to fix it with an adhesive or a staple.

As shown in FIG. 3, when the band is fixed to the anchor body 100, the band is fixed to have a longer trapezoidal shape than the upper portion so that the anchor body 100 has both ends 130 and 130 ' Thereby making it possible to increase the fixing force of the anchor body 100 inserted into the bone.

The anchor according to the present invention having the above-described structure is different from the conventional art in that the anchor body 100 inserted into the bone through the fixing means 200 fixing the contact portion 120 easily maintains the omega shape, And has an effect of being fixed in the inside of the bone.
