Description

Urinary incontinence mesh and weaving method

The present invention relates to a mesh for treating urinary incontinence and a method of weaving the same, and more particularly, to prevent injuries on human tissues by forming intact eyes formed on the sides of a single mesh, in particular, such a single mesh. When forming the woven fabric consisting of the side of the single mesh is combined with a single strand to form a woven fabric, but through the easy unwinding of the single strand is characterized in that weaving so that the single mesh can be easily separated from the woven fabric one by one It relates to a urinary incontinence treatment mesh and a weaving method thereof.

Urinary incontinence is a phenomenon in which urine is irrelevant regardless of one's will, and the prevalence rate is increasing as the average life expectancy is extended and the elderly are increasing. Types of urinary incontinence include urinary incontinence, which causes urine to be discharged without any inducing factor, stressive incontinence that occurs when the abdominal pressure rises due to coughing, urge urinary incontinence that does not hold the urine when you want to urinate, or overflowing urine in the bladder There is first class incontinence.

Such urinary incontinence is caused by not being able to easily control the opening and closing of the urethra, which is a passage through which urine is discharged to the outside, and can control the discharge of urine by binding and fixing the urethra slightly with a mesh.

On the other hand, the urinary incontinence treatment mesh as a monofilament yarn as a woven braid form, such a urinary incontinence treatment mesh remains in the body after the procedure in accordance with the above procedure to support or fix the urethra do.

Briefly looking at the process of making the urinary incontinence treatment mesh, woven with a woven cloth with a monofilament polypropylene yarn, then cut with a laser to make a single mesh, and then formed a heat shrink tube connected to the guide thread at both ends of the single mesh This is accomplished by doing.

At this time, the single mesh is made by cutting the woven fabric with a laser. Due to the cutting process, the meshes formed on both sides of the mesh are not maintained in an intact shape, and numerous sharp cuts are formed.

Such cuts often have a sharp cross section that frequently injures the tissue surface of the urethra during surgery, as well as injuries to the surface of the urethra that is fixed and supported even during the surgery. There is a very high probability of causing tissue necrosis.

In order to solve the above problems, as described in the following prior art document, the man eyes formed on both sides of a single mesh are formed intact, so that both sides are formed in a smooth curve, and the invention to solve the above problems. (Korean Registered Patent No. 10-877288 'Urinary Incontinence Treatment Sling') has been devised.

However, the above design is not only limited to one mesh but also a detailed description of what weaving structure or weaving method is woven is omitted, and due to the characteristics of the manufacturing operation of the urinary incontinence treatment mesh, weaving fabrics using a knitting machine are used. First forming, and then inevitably undergoes a process of cutting the woven fabric to form a single mesh, in the above prior art document is described only for the single mesh.

As shown in Figure 1, the urinary incontinence treatment mesh according to the present invention has a structure as described in the solution of the problem, the description thereof is as described above will be omitted.

In addition, the urinary incontinence treatment mesh according to the present invention forms a woven fabric in a structure in which side portions of a single mesh are bonded to each other when weaving with a knitting machine, and more specifically, the joining portion formed by joining side portions of the mesh is made of a single strand. It is formed as a structure in which the meshes formed integrally with the side of the mesh.

More specifically, the meshes formed on the side of the one side mesh (A) and the meshes formed on the side of the other side mesh (B) corresponding to each other are coupled in a structure that meshes with each other, as shown in FIG. In the center of the meshes interlocked with each other are arranged in a line, the single strand (5) for joining the meshes is a simple strand-like single strand (5) is formed when joining the meshes in the single strand (5) ) Is formed by being folded, and when forming the linking ring, the linking ring n (5a) is first formed, and then the portion adjacent to the linking ring n (5a) is folded among the remaining portions of the single strand 5, and the linking ring n + Forming 1 (5b) is a structure for joining the man-eyes forming a coupling portion by the linkage of the single strand (5).

When explaining a structure in which the single strand is folded to form a linking ring to bond the meshes in more detail as described above, the linking ring n (5a) formed by folding a single strand is passed through the mesh on the one side of the mesh A1 (6). The single-stranded link n + 1 (5b) passes through the link n (5a) and then passes through the mesh B1 (7) of the other mesh (B). The link ring n + 2 (5c) of (5) passes through the link ring n + 1 (5b), and has the structure which passed through the mesh eye A2 (8) of one side mesh A.

At this time, when the link ring n (5a), n + 1 (5b), n + 2 (5c) passes through the eyes A1 (6), B1 (7), A2 (8) in turn It has a structure that passes from the bottom of the mesh to the top.

It will be described in more detail for the process of forming the above structure.

Coupling portion C is arranged in a straight line as described above is formed by combining into a single strand (5), one end of the single strand (5) is located on the outside of the mesh, adjacent to the one end The surplus of the single strand (5) is passed through the mesh eye A1 (6) by the link ring n (5a) formed in a ring shape, and then the surplus of the single strand (5) adjacent to the link ring n (5a). The link ring n + 1 (5b) formed at the end passes through the link ring n (5a) passing through the mesh A1 (6), and then immediately passes through the mesh B1 (7).

Subsequently, after forming the linking ring n + 1 (5b) of the single strand (5) to form a linking ring n + 2 (5c) to the portion adjacent to the linking ring n + 1 (5b) of the surplus portion, The link n + 2 (5c) passes through the link n + 1 (5b) passing through the mesh B1 (7), and then passes through the mesh A2 (8).

Here, if the mesh eye A1 (6) is the mesh eye formed at the side of one side mesh A, the mesh eye B1 (7) is the mesh eye formed at the side of the other side mesh B, and the mesh eye A2 (8) is the side of the one side mesh A. It can be said that the mesh formed on the side of the mesh A1 (6) formed by the side, by the repeated coupling method and coupling structure such that the two meshes can be combined into a single strand between the sides, such a coupling structure is gathered weaving cloth It will form.

When the single mesh is separated from the woven fabric composed of a plurality of single meshes by the above-described bonding structure, when the other end is pulled out of both ends of the single strand forming the joining portion of the single mesh, the cutting is not necessary. Bonding is released as opposed to bonding, which will be described based on the description of the bonding structure.

That is, when pulling the other end of the single strand 5 of the link ring n + 2 (5c) passing through the mesh eye A2 (8) in the bond structure forming the above-described linking portion, the link ring n + 2 (5c) The single strand (5) releases the blind eye A2 (8) as it escapes from the blind eye A2 (8), and subsequently escapes from the link n + 1 (5b), which leads to the link n + 1 (5b) and the blind eye B1. The coupling structure of (7) is the same as the coupling structure of the mesh eye A2 (8) and the link ring n + 2 (5c). As described above, the coupling ring n + 2 (5c) is pulled out from the mesh eye A2 (8). As described above, the connection ring n + 1 (5b) is released from the mesh B1 (7) and the mesh B1 (7) is also released from the coupling part C.

As the coupling portion C having the coupling and unwinding structure as described above, the woven fabric can be formed with a plurality of single meshes, as well as through the removal of the single strand 5 forming the coupling portion C. It is possible to easily separate a single mesh from the.

On the other hand, the surgical mesh for treating urinary incontinence made of the above weave structure and weaving method is woven into four bars having about 40 to 80 courses per inch and about 7 to 11 wales per inch. However, the front bar for one side of both sides of a single mesh is 1-0, 2-2, 1-0, 2-2, 1-0, 2-2, 1-0, 2-2 The middle bar, which is set to the middle of a single mesh, is 1-0, 1-2, 1-0, 1-2, 1-0, 1-2, 1-0, 1-2 The back bar, which is responsible for the other side of both sides of a single mesh, is set to 0-0, 1-2, 1-0, 1-2, 0-0, 1-2, 0-0, 1- The connecting bar, which is set to 2 and serves as a coupling part for connecting the sides of the single mesh as a single strand, is 1-0, 0-1, 1-0, 0-1, 1-0, 0-1, 1- It is set as 0, 0-1, as shown in Table 1.
