Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

The present invention relates to a tissue suspending device for pulling and fixing a diseased skin tissue in a direction opposite to the direction of retraction (for example, when the retraction direction is referred to as gravity direction, the opposite direction means gravity opposite direction).

1 and 2, the first embodiment of the tissue pendant fixing device 100 includes a pair of leg portions 110 and a pendulum holding portion 140. As shown in Fig.

The pair of legs 110 include a distal portion 120 disposed on the side of the diseased skin requiring pulling and a proximal portion 130 connected to the distal portion 120 and pulling the distal portion 120 in a direction opposite to the proximal direction .

The distal portion 120 is composed of a threaded first core member 121 disposed on the side of the stray skin requiring pulling and having a locking projection 122 formed on its surface. Such a distal portion 120 is configured to allow the initial force of perturbation to the surrounding tissue to be maintained in the surrounding tissue until the tissue is sufficiently grown and the adhesion to the tissue is firmly established in a member having a plurality of pores of the proximal portion 130 and the pendent portion 140 anchor-holding power).

Examples of the material constituting the distal portion 120 include polydioxanone, poly- (1-lactic acid), polyglycolic acid (polyglycolic acid) which are harmless to the human body and are absorbed into the living body over time, it is preferable to use a biocompatible medical polymer material composed of a bioabsorbable medical polymer material, polypropylene, and a mixture thereof, which is a copolymer of polylactic acid, polycaprolactone and a copolymer thereof.

The first core member 121 has a substantially thread-like shape, and a locking protrusion 122 is provided on the surface of the first core member 121. The locking protrusion 122 may be formed in a visible shape so as to be able to pull the tissue that is sagged when inserted into the skin, and may be inclined toward the proximal portion. At this time, it is preferable that each of the first core members 121 is arranged in a pair and the engaging protrusions 122 disposed on the respective first core members 121 are inclined toward the adjacent proximal portion 130.

The proximal portion 130 is connected to the distal portion 120 and functions to pull the distal portion 120 in a direction opposite to the proximal direction. Specifically, the proximal portion 130 connects the tissue adhered to the distal end portion 120 to the suspension fixing portion 140, and the in-tissue growth progresses to the second air gap member 132 having a plurality of pores. So as to firmly adhere to the tissue and thereby reduce the load applied to the latching member 122 of the distal portion 120 with time.

 The second air gap member 132 may have the form of a porous mesh as a member having a plurality of voids. The second air gap member 132 may have a three-dimensional network shape and may have a tube-like shape. The second gap member 132 is integrated with the second core member 131 and can be processed by extrusion molding, injection molding, weaving, braiding, finishing, cutting, heat bonding or the like. As the material constituting the second gap member 132, any biocompatible material harmless to the human body can be used. The gap of the second gap member 132 may be any shape as long as the surrounding tissue can be easily grown in the tissue when inserted into the skin.

The second gap member 132 is designed to be deformed by the central core member 131 even though it is pulled in one direction and is configured to continuously extend from one end of the proximal portion 130 to the other end of the proximal portion 130 . The second air gap member 132 is a function opposite to the members used in fields such as urinary incontinence, hernia, and breast drainage, which must minimize adhesion with the surrounding tissues, thereby maximizing adhesion to tissues, .

The second gap member 132 is designed to reinforce the second core member 131 at the center, thereby increasing the tensile force. The surface area of the second gap member 132 is much higher than that of conventional products, thereby increasing the wound response with the tissue, Synthesis is induced to effectively expose the wrinkled skin while at the same time slowing down the rate of degradation in vivo, thereby increasing the maintenance period.

The second core member 131 may be threaded by being connected to the proximal portion 130 and passing through the second gap member 132 while pulling the proximal portion 130 in the opposite direction. The second core member 131 is made of a biocompatible material harmless to the human body and connects the proximal portion 130 to the suspension portion 140 to maintain the pulling force. The second core member 131 may be fixed to both ends of the second gap member 132, but it is not limited thereto. It is also possible to integrate the second gap member 131 over the entire length of the second gap member 132 .

The pendant fixture 140 has an inverted U-shape including a member having a plurality of pores to facilitate suspension of the tissue attached to the winch 120 and the proximal portion 130, It is simple to perform without a separate fixation device, but it can be fixed firmly due to growth in tissue, prevention of cheese and kidnapping phenomenon after the operation, integral fixed part, and the like, thereby enhancing the fixing effect of the tissue.

In order to form the inverted U-shaped portion of the suspension fixing portion 140, various methods of bending the U-shaped portion by applying a force to the U-shaped portion by applying a force to the U-shaped portion may be used .

The hanging portion 140 is formed in a reverse "U" shape so as to interconnect the pair of leg portions 110 and to be fixed in the skin tissue, and the third air gap member 142 and the third core member 141 ).

The third air gap member 142 is integrally connected to the second air gap member 132 by providing a plurality of voids to induce in-tissue growth. The third air gap member 132 has a three-dimensional tube shape and a mesh shape. The third air gap member 132 is formed by extrusion molding, injection molding, weaving, braiding, finishing, cutting, Bonding or the like.

 The third core member 141 is connected to the second core member 131 and penetrates the third gap member 142 and interconnects the pair of second core members 131. The third core member 131 is made of a biocompatible material and is coupled to the third air gap member 132. The third core member 141 is configured to connect the pair of second core members 131 continuously.

3 and 4, and the suspending fixture of this second embodiment is similar to that of the first embodiment, but the second air gap member and the third The shape and shape of the gap member are somewhat different. Specifically, in the first embodiment, the second air gap member and the third air gap member all have a three-dimensional shape such as a tube. However, the present invention is not limited to this, It is possible for the first electrode 232 to have a two-dimensional flat plate shape. However, if it is a two-dimensional shape, it is not limited to a quadrangular planar shape, and various planar shapes are possible. Although not shown in the drawing, it goes without saying that the second void member has not only a two-dimensional or three-dimensional shape but also a combination of two-dimensional and three-dimensional shapes.

5 and 6, the suspending fixture 300 according to the third embodiment is provided with the second core member 331 in a visible-type locking protrusion (not shown) 331-1) are formed. When the second core member 331 is also formed with the visible-type engaging projection 331-1, there is an advantage that it is advantageous in securing the initial breaking force.

7, the suspending fixation apparatus 400 according to the fourth embodiment of the present invention is shown in FIG. 7. In the suspending fixation apparatus 400 according to the fourth embodiment, The two core members 431 are formed to penetrate through the second gap member 432 in which a plurality of pores of the proximal portion 430 are formed. That is, the second core member 431 does not extend continuously from one end to the other end of the second air gap member but extends only to a predetermined length from one end of the second air gap member 432. When the second core member is provided over the entire length of the second cavity member as in the first to third embodiments, it is advantageous in terms of the tensile force, and in the case where the second core member is formed only in a part as in the fourth embodiment There is an advantage that a foreign body feeling is minimized.

The suspension fixture 500 according to the fifth embodiment of the present invention is shown in Fig. 8, and thus the suspension fixture disclosed in Fig. 8 is characterized in that the second gap member 532 is connected to the third gap member 542 It is exemplified that they are not connected integrally but are disconnected. That is, it is possible to have a discontinuous shape.
