Description

Technical Field

[0001] This application relates to the field of medical devices, and in particular to a reversible wound closure device. Background Technology

[0002] A wound closure device is a medical device that can quickly and effectively close various open wounds (including surgical wounds, traumatic wounds, etc.). By closing a wound with a wound closure device, only a linear scar remains after the wound heals, greatly improving the aesthetics of the healed wound.

[0003] However, existing wound closure devices cannot be reversed after closing the wound. If the doctor operates too much, it will cause the wound to be over-closed, which will not only reduce the patient's comfort, but also prolong the wound healing time. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this application provides a reversible wound closure device.

[0005] The reversible wound closure device provided in this application adopts the following technical solution: A reversible wound closure device includes two adhesive tapes for attaching to both sides of a wound, and a pull-open assembly disposed between the two adhesive tapes. The pull-open assembly includes a pull rod disposed on one of the adhesive tapes and a fixing seat disposed on the other adhesive tape. The pull rod is slidably inserted into the fixing seat along the arrangement direction of the two adhesive tapes. The pull-open assembly also includes an adjustment module for locking or unlocking the pull rod and the fixing seat relative to each other.

[0006] By adopting the above technical solution, the two tapes can move closer or further apart under the sliding cooperation of the pull rod and the fixing seat, so as to realize the closure or retraction of the wound closure device, which makes it easier for doctors to adjust the tightness of the wound closure, effectively improving the patient's comfort and shortening the wound healing time.

[0007] In one specific implementation, there are multiple pull-together components, and the arrangement direction of the multiple pull-together components is perpendicular to the arrangement direction of the two tapes.

[0008] By adopting the above technical solution, multiple pull-and-close components can achieve the overall closure of the two tapes, avoiding tape displacement during the closure process and effectively improving the wound closure effect.

[0009] In one specific implementation, a pull groove is provided through the fixing seat, the pull groove extends along the arrangement direction of the two tapes, and the pull rod is slidably inserted into the pull groove.

[0010] By adopting the above technical solution, the smoothness of the relative sliding between the pull rod and the fixed seat is effectively improved, reducing the difficulty of operation for doctors.

[0011] In one specific implementation, the adjustment module is mounted on the fixed base, the pull rod is located between the adjustment module and the bottom surface of the pull groove, and the distance between the adjustment module and the bottom surface of the pull groove gradually decreases along the direction from the pull rod to the fixed base.

[0012] By adopting the above technical solution, the pull rod can gradually approach the adjustment module as it moves toward the fixed seat, making it easier for the adjustment module to lock or unlock the pull rod.

[0013] In one specific implementation, the pull groove has a bearing portion, and the bearing portion has an arc-shaped bearing surface on the side near the adjustment module. The bearing surface is inclined towards the adjustment module along the direction from the pull rod to the fixed seat.

[0014] By adopting the above technical solution, the inclined arc-shaped bearing surface not only facilitates the adjustment module to lock or unlock the tie rod, but also further improves the smoothness of the tie rod sliding in the pull groove.

[0015] In one specific implementation, the pull rod is provided with a plurality of ratchet teeth along its length direction, and a locking groove is formed between each pair of adjacent ratchet teeth. The adjustment module includes a locking block provided on the fixed base, the locking block being positioned toward the ratchet teeth and capable of being embedded in any one of the locking grooves.

[0016] By adopting the above technical solution, the locking block can be embedded in the locking groove after the pull rod moves into place, which effectively improves the closing strength of the wound closure device.

[0017] In one specific implementation, the adjustment module further includes a locking handle disposed on the fixed base, the locking handle being deformably disposed along a direction close to or away from the ratchet, and the locking block being disposed on the side of the locking handle facing the ratchet.

[0018] By adopting the above technical solution, when the wound is over-closed, the lock block can be disengaged from the lock groove by pushing the lock handle outward, so as to restore the wound closure device.

[0019] In one specific implementation, the mounting base has an operating port, and the lock handle is installed in the operating port and bent in a direction away from the ratchet.

[0020] By adopting the above technical solution, doctors can easily grasp and operate the lock handle.

[0021] In one specific implementation, each of the two tapes is provided with a reinforcing plate, and the pull rod and the fixing seat are respectively mounted on the two reinforcing plates.

[0022] By adopting the above technical solution, the structural strength of the tape is effectively improved, preventing damage to the tape during the closing process.

[0023] In one specific implementation, the tape includes a first tape body and a second tape body respectively disposed on both sides of the reinforcing plate. The second tape body has an installation opening for exposing the reinforcing plate, and the pull rod and the fixing seat are respectively disposed in the installation opening.

[0024] By adopting the above technical solution, the second belt can shield the reinforcing plate, preventing the reinforcing plate from touching the patient's body and causing injury.

[0025] In summary, this application includes at least one of the following beneficial technical effects: The two tapes can move closer or further apart through the sliding cooperation between the pull rod and the fixing seat to achieve the closure or retraction of the wound closure device. This allows doctors to adjust the tightness of the wound closure, effectively improving patient comfort and shortening wound healing time. Attached Figure Description

[0029] The present application will be further described in detail below with reference to the accompanying drawings.

[0030] See Figure 1-2As shown, a reversible wound closure device includes two adhesive tapes 1 for attaching to both sides of a wound, and a pull-close assembly 2 disposed between the two adhesive tapes 1. The two adhesive tapes 1 are a first adhesive tape and a second adhesive tape. The pull-close assembly 2 includes a pull rod 21 disposed on the first adhesive tape and a fixing seat 22 disposed on the second adhesive tape. The pull rod 21 is slidably inserted into the fixing seat 22 along the arrangement direction of the two adhesive tapes 1. The pull-close assembly 2 also includes an adjustment module 23 for locking or unlocking the pull rod 21 and the fixing seat 22 relative to each other.

[0031] When closing the wound, the first and second adhesive tapes are applied to both sides of the wound, and then the lever 21 is pulled. The lever 21 moves the first adhesive tape closer to the second adhesive tape. After the pull is in place, the adjustment module 23 locks the lever 21 and the fixing seat 22 relative to each other, thereby closing the wound. If the pull is too tight, the lever 21 and the fixing seat 22 can be unlocked relative to each other through the adjustment module 23, and then the lever 21 can be pulled back to adjust the tightness of the wound closure. This effectively improves the patient's comfort and shortens the wound healing time.

[0032] In this embodiment, there are two pull-close components 2, and the arrangement direction of the two pull-close components 2 is perpendicular to the arrangement direction of the two adhesive tapes 1. The two pull-close components 2 can realize the overall closure of the two adhesive tapes 1, prevent the adhesive tapes 1 from shifting during the closure process, and effectively improve the wound closure effect.

[0033] In this embodiment, a pull groove 24 is provided through the fixed base 22. The pull groove 24 extends along the arrangement direction of the two tapes 1, and the pull rod 21 is slidably inserted into the pull groove 24.

[0034] The adjustment module 23 is mounted on the fixed base 22. The pull rod 21 is located between the adjustment module 23 and the bottom surface of the pull groove 24. The distance between the adjustment module 23 and the bottom surface of the pull groove 24 gradually decreases along the direction from the pull rod 21 to the fixed base 22. Furthermore, the pull groove 24 has a bearing portion 25. The bearing portion 25 has an arc-shaped bearing surface 251 on the side near the adjustment module 23. The bearing surface 251 is inclined towards the adjustment module 23 along the direction from the pull rod 21 to the fixed base 22. In this way, as the pull rod 21 moves towards the fixed base 22, it can gradually approach the adjustment module 23 under the guidance of the bearing surface 251, facilitating the adjustment module 23 to lock or unlock the pull rod 21. The inclined arc-shaped bearing surface 251 also improves the smoothness of the pull rod 21 sliding within the pull groove 24.

[0035] In this embodiment, the pull rod 21 has a plurality of ratchet teeth 26 along its length, and a locking groove 27 is formed between each pair of adjacent ratchet teeth 26. The adjustment module 23 includes a locking block 231 disposed on the fixed base 22. The locking block 231 is disposed facing the ratchet teeth 26 and can be engaged in any one of the locking grooves 27. The locking block 231 can be engaged in the locking groove 27 after the pull rod 21 is moved into place, effectively improving the closure strength of the wound closure device.

[0036] Furthermore, the fixed base 22 has an operating port 28, which communicates with the pull groove 24, and their arrangement direction is perpendicular to the extension direction of the pull groove 24. The adjustment module 23 also includes a locking handle 232 installed in the operating port 28 and bent in a direction away from the ratchet 26. The locking handle 232 is made of a deformable material and is deformably arranged in a direction close to or away from the ratchet 26. A locking block 231 is disposed on the side of the locking handle 232 facing the ratchet 26. When the wound is over-closed, the locking block 231 can be disengaged from the locking groove 27 by pushing the locking handle 232 outward to unlock the pull rod 21, thereby enabling the wound closure device to be repositioned.

[0037] In this embodiment, two reinforcing plates 3 are respectively provided on the two adhesive tapes 1, and the pull rod 21 and the fixing seat 22 are respectively installed on the two reinforcing plates 3. The adhesive tape 1 includes a first tape body 11 and a second tape body 12 respectively provided on both sides of the reinforcing plate 3. The second tape body 12 has an installation opening 13 for exposing the reinforcing plate 3, and the pull rod 21 and the fixing seat 22 are respectively provided in the installation opening 13.

[0038] The reinforcing plate 3 effectively improves the structural strength of the tape 1 and prevents damage to the tape 1 during the closing process. In use, the first tape body 11 is placed against the body, and the second tape body 12 shields the reinforcing plate 3, preventing it from touching the patient's body and causing injury.

[0039] The implementation principle of a reversible wound closure device according to an embodiment of this application is as follows: the first tape and the second tape are respectively attached to both sides of the wound, and then the pull rod 21 is pulled. The pull rod 21 moves the first tape closer to the second tape. After the pull is closed, the adjustment module 23 locks the pull rod 21 and the fixed seat 22 relative to each other. If the pull is too tight, the pull rod 21 and the fixed seat 22 can be unlocked relative to each other through the adjustment module 23. Then the pull rod 21 is retracted and the tightness of the wound closure is adjusted.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
