Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a sling for treating urinary incontinence with pre-

More particularly, the present invention relates to a sling for treating urinary incontinence, which has a pretension function by folding a central portion of the mesh in a direction opposite to the urethra so as to perform a pretension function .

Urinary incontinence can be defined as a symptom of urge incontinence, in which the pressure in the bladder exceeds the maximum urethral resistance and causes involuntary urine drainage, due to a dysfunction of the bladder and urethra sphincter.

Urinary incontinence is a disease that occurs more frequently in women than in men. Specifically, incontinence is genuine incontinence, stress urinary incontinence, urge incontinence, and incontinent incontinence. The cause of urinary incontinence is the occurrence of functional defects in the tissues or ligaments that connect the vaginal wall, pelvic muscle, and pubis, or weak urethral sphincter muscle. Common causes include repeated muscle deformation, Birth, surgery, and loss of pelvic muscle tone.

In patients with urinary incontinence, coughing, sneezing, etc., the urine is leaked through the urethra irrespective of the physician '

The treatment methods of urinary incontinence include medication, surgery, and nonsurgical treatment. Anticholinergic agents, smooth muscle relaxants, and cardiovascular antidepressants are used for the drug therapy. Surgery, birch surgery, TOT, collagen injection, And non-invasive therapies include physical therapy and behavior therapy.

1 and 2 illustrate a surgical operation using a urinary incontinence device 100 and a sling 200. The operation of the urinary incontinence device 100 and the sling 200 is described in detail in Korean Patent No. 10-0877288 (registered on Dec. 26, 2008) FIG. 3 is a perspective view of a sling 200, and FIG. 4 is a perspective view of a urinary incontinence treatment device 100.

In the specific operation procedure, the central portion of the urethra 60 and the vaginae 62 are cut by 1 to 2 cm, and then the anchors 140 of the anchors 140 of the sling 200, So that the sling 200 is engaged with the needle portion 40. The knob 20 is held with the right hand so that the L 26 display of the knob 20 can be seen so that the needle portion 40 is positioned on the left side of the urethra 60, The needle portion 40 is inserted.

And then the fixing protrusion 44 is inserted into the fitting hole 142 of the other anchor 140 so that the sling 200 is engaged with the needle portion 40. Then, as shown in FIG. 2, the handle is gripped with the right hand so that the R (28) mark of the handle 20 can be seen, the needle portion 40 is positioned on the right side of the urethra, (40) is inserted. When the sling 200 is positioned at a predetermined position, the needle portion is moved backward.

When the sling is installed, the mesh portion 120 supports the lower portion of the urethra, and the anchor portion is fixed to the pelvic fascia on both sides of the vaginal opening. On the other hand, in order to support the lower portion of the urethra with a proper force, the mesh portion grips the center of the mesh portion 120 and adjusts the tension.

If the mesh part is too tightly pressed against the lower part of the urethra, it is difficult for the patient to urinate.

However, the process of adjusting the tension of the mesh portion is very cumbersome, and if the mesh portion is pulled downward, the width of the mesh portion becomes narrow.

If the width of the middle portion of the mesh portion supporting the urethra is narrowed, the urethra can not be stably supported, thereby reducing the effect of the sling operation.

The sling for treating urinary incontinence according to the present invention is used in a TOT operation or a sling operation performed on a urinary incontinence patient. Such urinary incontinence surgery commonly uses a soft mesh-like mesh to support the urinary incontinence to treat urinary incontinence .

As mentioned in the prior art, when using such a mesh, the mesh is adjusted to support the urethra with a proper tension after inserting the mesh into a specific part of the patient. At this time, excessive tension is applied to the mesh, Since the width of the mesh is deformed, the urethra can not be stably supported.

Hereinafter, the structure and operation of the mesh of the present invention will be described according to the embodiments of the present invention.

First, a first embodiment according to the present invention will be described.

FIG. 5 is a conceptual view of the incontinence treatment sling according to the first embodiment of the present invention before the first folding retaining member is mounted. FIG. 6 is a cross- Fig. 7 is a perspective view showing a combined state of the pre-tension portion of the mesh and the first folding retaining mouth in Fig. 6, Fig. 8 is a perspective view of the first folding retaining mouth of Fig. 7, FIG. 9 is a perspective view of the first folding support of FIG. 8, FIG. 10 is a partial perspective view of the second support of the first folding support of FIG. 8, FIG. 12 is a sectional view of the first folding holding tool of FIG. 8, and FIG. 13 is a sectional view of the first folding holding tool of FIG.

The sling for treating urinary incontinence in this embodiment is made up of the mesh 110, the anchor 120, and the folded temporary occasion member 130A.

The mesh 110 is a mesh structure with elasticity and a part of the anchor 120 and the mesh 110 are inserted into the body near the quality of the patient and the mesh 110 exposed to the outside of the body is drawn in a concave shape, Not shown).

In this embodiment, the portion of the patient to be left on the body is the mesh 110 and the anchor 120.

The mesh 110 generally extends in the longitudinal direction as a mesh structure, and the anchor 120 is coupled to both longitudinal ends of the mesh 110.

The mesh 110 of the present embodiment forms a pretensioning portion 111 that is folded while its longitudinal center portion protrudes in the direction opposite to the urethra.

Since the pre-tension unit 111 is simply folded, if the tensile force is applied to the anchor 120 without a separate holding device, the pre-tension unit 111 will be flattened like the other parts of the mesh 110.

A folding temporary holding member 130A is provided to temporarily hold the folded state of the pretensioning unit 111. [

The folding temporary holding member 130A of this embodiment is the first folding holding tool 130A.

The folding temporary holding member 130A temporarily holds the folded state of the pretensioning unit 111 and must be temporarily removed and then removed. That is, the folding temporary holding member 130A is attached to the pretensioning unit 111 to temporarily hold the folded state of the pretensioning unit 111 at the time of incontinence surgery, and is removed after the operation.

The first folding support 130A temporarily holds the folded state of the pretensioning unit 111 by the first support 131 and the second support 132. [

One end of the first support 131 and one end of the second support 132 are connected to each other via a hinge 133.

Therefore, the first support 131 and the second support 132 can be opened or closed around the hinge 133. [

And the other end of the second support base 132 may be detachably coupled to the other end of the first support base 131. [

When the other end of the second support member 132 is fastened to the other end of the first support member 131, the first support member 131 and the second support member 132 are in parallel with each other to maintain the state of the pre- .

When the other end of the second support base 132 is fastened from the other end of the first support base 131, the first support base 131 and the second support base 132 are spread apart from each other, Is released.

A plurality of protrusions 132a (three protrusions are formed in the case of this embodiment) for fixing the mesh 110, specifically, the pretensioning unit 111 are attached to the second support base 132 by the first support base 131 And the first support base 131 is formed with an insertion hole 131a (in the case of the present embodiment, a long hole shape) for inserting the tip of the projection 132a.

In addition, a support protrusion 132b is protruded from the second support base 132 toward the first support base 131 in the longitudinal direction thereof. The supporting step 132b is formed to maintain the first supporting part 131 and the second supporting part 132 in close contact with each other when the first supporting part 131 and the second supporting part 132 are engaged with each other .

The first folding support member 130A has a first support base 131 and a second support base 132 after the preliminary tension unit 111 is inserted between the first support base 131 and the second support base 132, The pre-tension part 111 is sandwiched between the protrusion 132a and the insertion hole 131a, and the shape of the pre-tension part 111 is maintained.

If incontinence surgery is performed using the sling for treating incontinence in this state, the mesh 110 is pre-tensioned, and after the incontinence operation, the first folding retention opening 130A is removed from the pretensioning portion 111 The pre-tension part 111 is unfolded in its original shape (i.e., in a spread state), so that the tension applied to the mesh 110 is reduced, so that the mesh 110 can accurately and reliably support the urethra .

Particularly, in the present embodiment, since the pretension portion 111 protrudes in the direction opposite to the urethra, the first fold holding tool 130A is also located in the opposite direction to the urethra, It is very convenient to remove the first folding holding tool 130A because it can be removed from the opposite side of the body. In addition, since the first folding holding tool 130A is located on the opposite side of the body of the patient, the foreign body feeling of the patient due to the first folding holding tool 130A can be minimized.

Removal of the first folding holding tool 130A is very easily accomplished by releasing the engagement between the other end of the first support 131 and the other end of the second support 132. [

Hereinafter, a second embodiment of the present invention will be described.

FIG. 14 is a conceptual view of a state in which a pretension portion is held in a folded state by a second folding retaining mouth coupled to a sling for treating incontinence according to the second embodiment of the present invention, FIG. 15 is a cross- Fig. 16 is a plan view of the second folding and holding tool of Fig. 14; Fig.

In this embodiment, as the folding temporary holding member, the second folding holding tool 130B is used in place of the first folding holding tool 130A, and the rest are the same as in the first embodiment.

The second folding holding tool 130B includes a gripping type gripping body 134 having fastening teeth 135 formed on both sides of its distal end and a gripping body 136 formed on the gripping body 134 to open the gripping body 134. [ ).

When the bulging member 136 formed on both sides of the grip member 136 is pressed, the gripper body 134 is opened. When no external force is applied to the grip member 136, The fixed teeth 135 formed on both sides of the tip are engaged with each other to fix the pre-tension part 111. [

A third embodiment according to the present invention will be described below.

FIG. 17 is a photograph of a state in which the fixing thread is stuck to the sling for treatment of incontinence according to the third embodiment of the present invention and the pretension part is kept in a folded state. FIG. 18 is a cross- This is an enlarged photograph of a state in which the fixing thread is stuck to the sling and the shape of the pretension portion is maintained.

In the present embodiment, the fixing chamber 130C, which is stuck to the pretensioning portion 111, is used as the folding temporary holding member.

The fixing chamber 130C is stuck to the pretensioning portion 111 to maintain the shape of the pretensioning portion 111. [

When the one end of the fixing chamber 130C is pulled in one direction, the fixing chamber 130C can be detached from the pre-tension portion 111 while the fixing thread 130C is released. This type of stitching is a commonly used method for sealing rice bags.

In addition, a grip portion 137 may be separately provided at one end of the fixing chamber 130C so that the grip portion can be easily gripped and pulled.

On the other hand, the foregoing examples have been described on the assumption that a separate structure is provided to remove the folding temporary holding members, and the operator removes the folding temporary holding member directly.

However, the folded temporary holding member may be removed by adopting a material that is removed naturally without having a separate structure necessary for removal.

That is, the folding temporary holding members may be made of a material which is decomposed in the body.

If the folding temporary holding member is a substance that is decomposed in the body, the incontinence operation proceeds in a state in which the shape of the pretensioning unit 111 is maintained by the folding temporary holding member, and the folding temporary holding member after the incontinence operation is within a few minutes So that a separate process for removing the folded temporary holding member becomes unnecessary.

Examples of the substance decomposed in the body include polyglycolide (PGA), polydioxanone (PDO), polylactide-co-glicolide (PLGA), and the like, or copolymers thereof.

In particular, if the fixation chamber 130C is made of a material that is decomposed in the body, the fixation chamber 130C is not stuck in a manner of being pulled by pulling one end as in the third embodiment, As shown in Fig.

It will be understood by those skilled in the art that the foregoing description of the present invention is for illustrative purposes only and that those of ordinary skill in the art can readily understand that various changes and modifications may be made without departing from the spirit or essential characteristics of the present invention. will be.

It is therefore to be understood that the embodiments described above are intended to be illustrative, but not limiting, in all respects. For example, each component described as a single entity may be distributed and implemented, and components described as being distributed may also be implemented in a combined form.

The scope of the present invention is defined by the appended claims rather than the detailed description and all changes or modifications derived from the meaning and scope of the claims and their equivalents are to be construed as being included within the scope of the present invention do.
