Description

High Strength Soft Tissue Fixing Tool {strong sleeved suture}

The present invention relates to a soft tissue fixation tool used to fix soft tissues such as tendons, ligaments and muscles in bone using orthopedics in orthopedic surgery, and the outer peripheral surface adjacent to both ends of the sleeve is incised to increase surface area. The present invention relates to a high-strength soft tissue fixation tool, which has been turned on to enable the body to effectively fix soft tissue to bone.

In orthopedic surgery, rupture of soft tissues (tendons, ligaments, muscles) is the most common injury.

To reattach the soft tissue to the bone, a large incision is made and then a hole is made in the bone and passed through the suture, and the soft tissue is caught and attached to the bone, which is mostly performed through surgery and requires a long recovery period.

Recently, a procedure has been attempted to shorten the recovery period by performing surgery using arthroscopy after performing a minimal incision.

At this time, in order to reattach the soft tissue using an arthroscopy to attach the anchor to the bone and soft tissue attached, fixed method is used.

Conventional anchors used in this method used heavy anchors made of metals such as titanium, and these metal anchors had to be attached to the bones and had to be removed after surgery. There was a problem.

Recently, lightweight biocompatible plastics (PEEKs) have been developed to compensate for the shortcomings of these metals, but they also have the disadvantage of having to perform removal after surgery.

As a technique to compensate for the shortcomings of the materials, the "apparatus for fixing the suture to the tissue" (Korean Patent Publication No. 10-2010-0121531) in the bone tissue through the shank through the suture to the top in FIG. A method of insertion is disclosed, and a technique is disclosed in which the lower end of the shank portion protrudes.

The technique consists of an anchoring sleeve made of a material that can be liquefied by mechanical vibration to insert the suture and then secure the suture by curing the liquefied sleeve.

The above technology does not need to be removed after surgery when biocompatible plastics are developed and used as anchors to fix soft tissues, but biodegradable biocompatible plastic anchors are fragile and therefore have to be formed large in size. Unnecessarily large drill holes in the bone need to be drilled in the bone, so the use of a small number of anchors reduces the soft tissue holding force, and the weak anchor still retains the disadvantages of anchors or sutures under strong loads.

In other words, the bone anchor should be fixed to the bone, maintain the suture to hold the soft tissue, and should be robust, and small in size for a lot of fixing per unit area, but the present anchors presented in the related art have their disadvantages. It is necessary to develop a tool capable of efficiently fixing soft tissues to bones while overcoming the disadvantages of these anchors.

KR 10-2010-0121531 (2010.11.17)

The high-strength soft tissue fixing tool of the present invention is intended to solve the problems occurring in the prior art as described above, and does not form a large number of large holes in the bone while forming a small size of the hole while holding the soft tissue with suture bone soft tissue I want to be able to pin it efficiently.

Specifically, by forming an incision cut in the outer circumferential surface from the end of the sleeve through which the middle portion of the suture penetrates, the incision is opened in the process of pulling the suture after the sleeve is inserted into the hole formed in the bone with the suture connected. It is intended to improve the fixation strength of the soft tissue by pulling it while increasing the contact area with the.

This is to reduce the size or number of holes in the bone to simplify the procedure and to improve the speed of recovery.

In addition, the suture or sleeve is formed of a material such as UHMWPE while forming a biocompatible material to have excellent tensile strength and robustness to be able to resist strong forces.

In addition, both sides of the suture protruding through the sleeve to be visually differently recognized by the indication to the practitioner to have a discriminating power to reduce the rate of false surgery.

The high-strength soft tissue fixing tool of the present invention, in order to solve the above technical problem, is formed in the form of a tube open at both ends, the sleeve is formed with an incision cut out the outer peripheral surface to a certain distance from both ends; And a suture installed through the inside of the sleeve by penetrating both ends of the sleeve.

At this time, the sleeve has a tensile strength of 10.0 kgf ~ 30.0 kgf, characterized in that the firmness of 5.0 mgf ~ 15 mgf.

In addition, the suture is characterized in that the tensile strength is 10.0 kgf ~ 30.0 kgf, the firmness is 1.0 mgf ~ 5 mgf.

In addition, any one of the sleeve or suture is characterized in that made of a biocompatible material.

At this time, the suture is made of the same material as UHMWPE, the sleeve is characterized in that it comprises any one of UHMWPE, PET, PP, PC, PGA, PLA, PDO and the like.

In addition, the suture is characterized in that the identification mark is formed so that the two parts protruding based on the portion inserted into the sleeve to have a visual difference.

According to the present invention, the soft tissue can be efficiently fixed to the bone by holding the soft tissue with a suture while forming a small hole without forming a large number of large holes in the bone.

Specifically, by forming an incision cut in the outer circumferential surface from the end of the sleeve through which the middle portion of the suture penetrates, the incision is opened in the process of pulling the suture after the sleeve is inserted into the hole formed in the bone with the suture connected. It can be pulled while increasing the contact area with the soft tissue to improve the fixing strength.

This reduces the size or number of holes in the bone, making the procedure easier and speeding up recovery.

In addition, the suture or the sleeve is formed of a material such as UHMWPE while forming a biocompatible material to have excellent tensile strength and robustness to resist a strong force.

In addition, both sides of the suture protruding through the sleeve can be visually recognized differently, thereby allowing the practitioner to identify and reduce the rate of misoperation.

2 to 3 is a perspective view showing an example of the procedure according to the configuration of FIG.
Figure 4 is a perspective view showing a state when pulling the suture after penetrating through the paper to test the resistance of the high-strength soft tissue fasteners of the present invention.
Figure 5 is a perspective view showing an example of identifying the suture in the present invention.

The high-strength soft tissue fixing tool of the present invention is composed of a sleeve 20 and a suture 10, as shown in Figure 1, the sleeve 20 is formed in a tubular shape with both ends open, from both ends An incision 21 having an outer circumferential surface cut to a predetermined distance is formed, and the suture 10 is configured to have a structure installed through the inside of the sleeve 20 by penetrating both ends of the sleeve 20. .

Looking at the treatment method using the high-strength soft tissue fixing tool of the present invention configured as described above First, as shown in Figure 2 to form a hole (1a) in the bone 1, then the suture 10 is connected to the sleeve 20 is inserted The inner tube 31 is inserted into the hole 1a by using a tool configured to include the inner tube 31 and the outer tube 30 in which the inner tube 31 is accommodated.

Then, when the inner tube 31 is pulled outward, the incision 21 in which the outer circumferential surface of the sleeve 20 is cut while the suture 10 connected to the inner tube 31 moves to the outside of the hole 1a as shown in FIG. 3. ), And the soft tissue is pulled outward to have a firm connection with the bone tissue.

This configuration can be much simpler than when performing the procedure using a conventional anchor.

Figure 4 is a view of experiments using paper 40 to grasp the performance of the high-strength soft tissue fixing tool according to the present invention.

As shown in the drawing, a hole is formed in the paper 40 and the suture 10 to which the sleeve 20 is connected is passed through the hole so that the sleeve 20 is positioned at the top of the paper 40 and both sides of the suture 10 are formed. The tip was allowed to protrude to the bottom of the paper 40 and then pulled down the two sutures 10.

As a result, as the cutout 21 is opened, the inner surface of the sleeve 20 is spread evenly on the upper surface of the paper 40 so that the paper 40 is not easily torn.

When the paper 40 is assumed to be a bone, the incision 21 of the sleeve 20 is spread and the suture 10 is pulled as it is evenly contacted with the bone, so that the stress is evenly distributed so that the bone is not damaged. will be.

In other words, the high-strength soft tissue fixing tool of the present invention is because when the incision 21 is stretched and pulls the sleeve 20 and the suture 10 inserted in the bone evenly in contact with the bone to resist any of the sleeve 20 The force is not concentrated at the point so that it can be effectively fixed to the bone while preventing bone damage.

On the other hand, in such a configuration, the sleeve 20 and the suture 10 is preferably made of a material having a high tensile strength to withstand strong forces.

This is because the suture 10 or sleeve 20 does not boil due to the pulling force of the operator during the procedure. For this purpose, the sleeve 20 and the suture 10 have a tensile strength of 10.0 kgf or more, specifically 10.0 kgf. It is desirable to have a tensile strength of about 30.0 kgf.

In addition, the stiffness (stiffness) of the suture 10 is preferably about 1.0 mgf ~ 5 mgf, which is flexible to maintain the knot stability during surgery.

In addition, the sleeve 20 will preferably be in the range of 5.0 mgf ~ 15 mgf higher than the suture 10.

This is because the sleeve 20 must be firm enough to withstand pulling out so as to withstand stronger forces than the suture 10 and out of the hole.

In addition, the sleeve 20 is gathered or crumpled in the hole when the suture 10 is pulled because it serves to fix the length is 10-30 mm is suitable.

On the other hand, the sleeve 20 and the suture 10 is preferably made of a biocompatible material such as a homopolymer such as polydioxanone, polylactide, polycaprolactone, trimethylene carbonate or a copolymer containing them.

In particular, the suture 10 and the sleeve 20 is preferably formed of a material such as UHMWPE (ultra high molecular weight polyethylene) in order to maintain excellent tensile strength, in the case of the sleeve 20, PET, PP, PC, It may be made to include any one of PGA, PLA, PDO and the like.

In the above configuration, since the operator must work such as knotting the protruding suture 10, it is preferable to be able to distinguish two parts of the suture 10 protruding from both sides of the sleeve 20.

To this end, it is preferable to form the identification mark 11 as shown in FIG. 5 so as to have a visual difference in both or both portions of the suture 10 divided based on the sleeve 20.

The identification mark 11 may be applied to various methods such as a method of different colors, a method of forming a pattern, and a method of marking.

The present invention made as described above is configured so as to penetrate the suture 10 in the sleeve 20 of the slightly thicker than the thickness of the suture 10, so it does not occupy a large volume compared to the present bone anchor (1) Also when forming the hole (1a) has the advantage that the size is smaller and the recovery speed after surgery is faster.

Yet, the small sleeve 20 can efficiently fix the soft tissue to the bone 1 and have a high fixation strength by the incision 21.

Due to this high fixing strength it is possible to reduce the size or number of holes (1a) drilled in the bone (1).

The high-strength soft tissue fixation tool of the present invention may be used to fix various soft tissues such as muscle, fat, fascia, skin, etc. to the bone 1 or to each other.
