Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an adjustable skin wound closure device. Background Technology

[0002] In conventional surgery, wounds are treated by suturing. However, suturing leaves unsightly scars. Therefore, sutureless skin wound closure devices are usually used to promote wound healing and reduce the risk of scarring.

[0003] Currently, traditional sutureless skin wound closure devices cannot be reopened after closure. If excessive operation during the closure process causes the closure to be too tight, the tension needs to be readjusted, or the wound needs to be cleaned, the closure device needs to be reopened. Traditional skin wound closure devices are inconvenient to achieve the above purposes because they cannot be reopened. Utility Model Content

[0004] To address the aforementioned technical problems, the purpose of this invention is to provide an adjustable skin wound closure device. This skin wound closure device is easy to open, allows for convenient adjustment of tightness and wound cleaning, and improves ease of use.

Detailed Implementation

[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0023] like Figures 1 to 3 A preferred embodiment of an adjustable skin wound closure device is shown, comprising a base band assembly, a pull rod 3, and a locking seat 4. The base band assembly includes a first base band 1 and a second base band 2, both having an adhesive surface for skin contact. In this embodiment, the non-skin contact surfaces of the first base band 1 and the second base band 2 are also adhesive surfaces. The adjustable skin wound closure device further includes a first fixing reinforcement piece 5 and a second fixing reinforcement piece 6. The first fixing reinforcement piece 5 is fixed to the first base band 1 by adhesive bonding. The locking seat 4 is integrally formed with the first fixing reinforcement piece 5. The second fixing reinforcement piece 6 is fixed to the second base band 2 by adhesive bonding. One end of the pull rod 3 is integrally formed with the second fixing reinforcement piece 6. The other end of the pull rod 3 is connected to the locking seat 4 via a locking structure. The locking seat 4 has an open structure along the radial direction of the pull rod. In this embodiment, the open structure 41 is located on the side of the locking seat 4, allowing the pull rod 3 to disengage from the locking seat 4 through the open structure 41.

[0024] The pull rod 3 has a plurality of ratchet teeth 31 distributed along the axial direction, and the ratchet teeth 31 are conical teeth; the inner side of the locking seat 4 has a latch 42, the latch 42 has hook teeth, and the hook teeth of the latch 42 can engage and lock with the ratchet teeth 31. The ratchet teeth 31 and the latch 42 constitute the locking structure, so as to achieve the pulling and closing of the skin wound through the two base bands.

[0025] The adjustable skin wound closure device further includes a first cover plate 7 disposed on a first base band 1 and a second cover plate 8 disposed on a second base band 2. Both the first cover plate 7 and the second cover plate 8 are medical non-woven fabrics. Both the first cover plate 7 and the second cover plate 8 are provided with notches. The locking seat 4 protrudes from the notch of the first cover plate 7, and the end of the pull rod 3 fixed to the first base band 2 (i.e. the part that is combined with the second fixing reinforcement plate) protrudes from the notch of the second cover plate 8.

[0026] In this embodiment, the inner side of the locking seat 4 is provided with three limiting protrusions 43 that cooperate with the limiting of the pull rod. Among them, two limiting protrusions 43 are provided on the upper and lower sides of the open structure 41 of the locking seat 4. The limiting protrusions 43 are all arc-shaped. Through the limiting protrusions 43, the pull rod 3 can be more reliably limited in the locking seat 4, and the pull rod 3 can also be prevented from accidentally disengaging radially.

[0027] For ease of operation, the end of the lever 3 near the locking seat 4 also has an operating handle 32.

[0028] A release liner 9 is provided on the side of the baseband assembly that is attached to the skin. This release liner 9 can be removed when in use.

[0029] In this embodiment, there are two pull rods 3, and correspondingly, there are two first fixing reinforcing plates 5, two second fixing reinforcing plates 6, two locking seats 4, two first cover plates 7 and two second cover plates 8.

[0030] In use, remove the release paper 9 and place the adhesive side of the skin wound closure device on the skin, with the two base bands located on either side of the wound. Press slightly to ensure the two base bands adhere firmly to the skin. Pull the lever 3 by operating the handle 32. After stopping the pulling operation, the ratchet 31 on the lever 3 engages and locks with the latch 42 of the locking seat 4, closing the wound in the appropriate position. If the lever 3 is pulled too tight, causing discomfort to the wound, the lever 3 can be pulled out from the open structure 41 of the locking seat 4. After loosening, adjust the tension of the lever and then re-engage it into the locking seat 4 to return the lever 3 to the appropriate position, thus adjusting the tension. In addition, when it is necessary to clean the wound, the lever 3 can be pulled out to loosen the lever and perform the necessary cleaning operations.
