Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a wound surface tension-reducing and closing device. Background Art
[0002] Wound tension closure devices use the skin's own viscoelasticity to close the skin through a mechanical structure to achieve the principle of promoting primary closure of the wound. They have been widely used to treat various skin injuries, such as tissue expanders at irregular trauma sites to assist wound healing and reduce scar formation. Tissue expanders are invasive in nature and need to be placed subcutaneously in advance to gradually expand, and then taken out and re-sutured to the skin. This type of wound requires at least two surgeries, and there will also be local tissue tension, which often leads to problems such as necrosis of the tissue at the edge of the wound.
[0003] Wound skin closure devices are also used in the prior art, which use non-invasive fixation to close the wound surface, but their structure is relatively complex. To this end, the applicant has previously designed a wound skin closure device and applied for a utility model patent with application number 2023225866154, which better realizes the self-locking function of the lock. However, during processing and actual clinical applications, the applicant found that the assembly complexity of the closure device is still relatively high, and the internal elastic column is easily damaged during use.
[0004] To this end, the applicant further optimized and improved the lock structure and designed a new wound tension-reducing and closing device, which uses side teeth to achieve self-locking and simplifies the complex internal structure of the lock. The structure is simple and compact, easy to assemble, easy to operate, and not easy to damage, making it easy to promote and apply. Utility Model Content

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1
[0018] See also Figure 1-4The present embodiment provides a wound tension-reducing and closing device, the basic structural principle of which is the same as that of the existing skin tension-reducing and closing device, including a toothed bar 1, one end of which is fixedly connected to a toothed bar stretching plate 2, and a clutch stretching plate 3 that can move along the toothed bar 1 is provided on the toothed bar 1. As a conventional design, ventilation holes 10 should be provided on the toothed bar stretching plate 2 and the clutch stretching plate 3, adhesive glue is provided at the bottom of the toothed bar stretching plate 2 and the clutch stretching plate 3, and a clutch locking buckle is also provided on the clutch stretching plate 3. In the present application, the toothed bar and the clutch locking buckle are optimized and improved. A movable groove 4 is provided on the toothed bar 1, and limited internal clamping teeth 5 are arranged on the inner walls on both sides of the movable groove 4. A fixed plate 6 is provided on the upper front end of the clutch stretching plate 3, and the toothed bar 1 passes through the fixed plate 6 and is movably connected to the fixed plate 6. The clutch locking buckle includes two elastic plates 7 correspondingly arranged on the fixed plate 6, the elastic plates 7 are located in the movable groove 4, and the outer side of the elastic plates 7 is provided with a limiting outer clamping tooth 11 corresponding to the limiting inner clamping tooth 5, and the upper end of the elastic plate 7 is provided with a pressing plate 8 located on the upper side of the tooth groove bar 1. It should be noted that the relative tooth direction design of the limiting inner clamping tooth 5 and the limiting outer clamping tooth 6 is common knowledge familiar to those skilled in the art, and will not be repeated in this application.
[0019] In order to prevent the toothed bar 1 and the clutch tensioning plate 3 from being excessively deflected during relative movement, Figure 1 and Figure 3 As shown, an anti-deflection plate 9 is fixedly provided at the upper end of the clutch tensioning plate 3, the tooth groove bar 1 passes through the anti-deflection plate 9 and is movably connected with the anti-deflection plate 9, and a guide plate 12 located in the movable groove 4 is fixedly provided on the inner side of the anti-deflection plate 9. When the tooth groove bar 1 is about to deflect on the clutch tensioning plate 3, the guide plate 12 contacts with the inner wall of the movable groove 4 to play a resisting role and prevent the rack groove 1 from deflecting.

When in use, tear off the anti-sticking paper, stick the toothed strip stretching plate 2 and the clutch stretching plate 3 to the relative positions on both sides of the skin, pass the toothed strip 1 through the fixed plate 6 and the anti-deflection plate 9, so that the elastic plate 7 and the guide plate 12 are located inside the movable groove 4, and the spacing between the toothed strip stretching plate 2 and the clutch stretching plate 3 can be adjusted according to the scale line 13 by pulling the toothed strip 1;
[0023] When loosening is required, pinch the pressure plates 8 on both sides with the thumb and index finger, so that the elastic plate 7 drives the limiting outer clamping teeth 11 to move inward, so that the limiting outer clamping teeth 11 leave the limiting inner clamping teeth 5, and the tooth groove strip 1 can be released, and the wound can be treated or the distance between the two distraction plates can be readjusted.
