Abstract
Description
Technical Field
[0001] The present disclosure belongs to the field of medical devices, and particularly relates to a wound closure device for use after caesarean section. Background Art
[0002] Closing the wound after a cesarean section is an important step in ensuring postoperative recovery. Traditionally, the wound for a cesarean section is usually a transverse incision in the abdomen. Although this incision can effectively provide space for delivery, it also brings challenges to the closure of the postoperative wound. In the prior art, a common way to close the wound is to use a clamp to clamp the skin on both sides of the wound. However, when using a clamp to clamp the skin on both sides of the wound, the clamp will exert continuous pressure on the skin during long-term use. This pressure not only compresses the skin, but may also cause the blood circulation of the skin to be restricted, thereby increasing the risk of skin damage, which is specifically manifested as ischemia and necrosis of the skin tissue, and may even cause complications such as wound dehiscence. Since the wound after a cesarean section is large, this problem is particularly prominent and may affect the healing speed and quality of the postoperative wound; therefore, the wound closure device in the prior art has the problem of compressing and damaging the skin at the wound for a long time when used. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of the present disclosure is to provide a wound closure device for use after cesarean section, which solves the problem that the wound closure device in the existing technology may compress and damage the skin at the wound for a long time during use.

[0030] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present disclosure.
[0031] Combined with this Figures 1 to 5An embodiment of a post-cesarean section wound closure device is described below. Specifically, the post-cesarean section wound closure device is constructed as a split structure, comprising a fixing plate 100, a slide groove 101, a slider 200, a screw 300, a strip plate 400, and a bandage 600. Two medical tapes are attached to the sides of the wound. By pulling the two medical tapes 500 closer together, the skin on both sides of the wound is closed, thus resolving the problem of prior art wound closure devices causing prolonged pressure and damage to the wound skin.
[0032] Please refer to Figures 1 to 5 , a wound closure device for use after cesarean section, comprising a fixing plate 100;
[0033] The fixing plate 100 is placed vertically, and a sliding groove 101 is provided at the middle of any side wall of the fixing plate 100.
[0034] A pair of symmetrically placed sliders 200 are slidably engaged in the chute 101. A coaxially placed screw 300 is rotatably connected in the chute 101. The screws 300 are located on opposite sides of the symmetry plane of the two sliders 200 and have opposite spiral directions. The sliders 200 are both sleeved on the screw 300 and threadedly connected thereto.
[0035] A horizontally placed strip plate 400 is fixed to one end of the slider 200 away from the fixing plate 100. A medical tape 500 is provided on the side of the strip plate 400 away from the fixing plate 100. The medical tape 500 is used to adhere to the patient's abdominal skin on the side away from the fixing plate 100.
[0036] A pair of symmetrically placed straps 600 are provided at both ends of the fixing plate 100 along the axis direction of the strip plate 400. The two straps 600 are fixed to both ends of the fixing plate 100 respectively.
[0037] The fixing plate 100 is usually made of corrosion-resistant and easy-to-clean materials to ensure the hygiene of the surgical environment. Commonly used materials include high-strength plastic or aluminum alloy. The surface of the slide 101 can be specially treated, such as polishing, to reduce the wear of the slider 200.
[0038] The screw 300 is generally made of stainless steel or carbide, which has high strength and corrosion resistance and can withstand the operating pressure of the reverse thread. The thread of the screw 300 is precisely processed to ensure good fit with the slider 200 and smooth rotation.
[0039] Medical tape 500 is typically made of medical-grade adhesives and soft fabrics or non-woven fabrics to ensure skin fit and safety. It can be designed to be highly breathable and non-irritating to reduce the risk of postoperative infection and improve patient comfort.
[0040] Since the wound of cesarean section surgery is a transverse incision on the abdomen, when using, first place the two shaped plates 400 on the upper and lower sides of the cesarean section surgery wound respectively, then push the fixing plate 100, the slider 200, the strip plate 400 and the medical tape, so that the two medical tapes are attached to the skin of the patient's abdomen near the upper and lower ends of the wound; then rotate the screw rod 300, the screw rod 300 drives the slider 200 to perform thread transmission, and the slider 200 drives the two shaped plates 400 and the medical tape, so that the two medical tapes drive the skin of the upper and lower ends of the incision to move closer to each other until they are tightly attached, and finally, the two bandages 600 are wrapped from the patient's abdomen to the patient's back, and the ends of the two bandages 600 away from the fixing plate 100 are tied and bound on the patient's back;
[0041] In the prior art, when clamping the skin on both sides of the wound to close it, the skin at the wound is compressed for a long time, which can easily cause skin loss at the patient's wound and is not conducive to postoperative wound healing.
[0042] In the present application, two medical tapes are attached to both sides of the wound, and the skin on both sides of the wound is closed by pulling the two medical tapes 500 closer to each other, thereby solving the problem in the prior art that the wound closure device will compress and damage the skin at the wound for a long time when used.
[0043] During use, the sweat secreted by the patient will cause the viscosity of the medical tape 500 to gradually decrease. Therefore, the medical tape 500 needs to be replaced after a period of use. The medical tape 500 is detachably connected to the corresponding strip plate 400, so that the medical tape 500 can be removed and replaced after a period of use.
[0044] A rectangular frame 700 is provided on the side of the strip plate 400 away from the fixed plate 100, and a frame groove 401 adapted to the rectangular frame 700 is opened on the strip plate 400. The medical tape 500 is placed between the strip plate 400 and the rectangular frame 700. The rectangular frame 700 is used to press the edges of the medical tape 500 into the frame groove 401; the edges of the medical tape 500 can be pressed into the frame groove 401 through the rectangular frame 700. When the medical tape 500 needs to be replaced, the rectangular frame 700 is first separated from the frame groove 401, and then a new medical tape 500 can be replaced.
[0045] In order to automatically control the connection or separation of the rectangular frame 700 and the frame groove 401, a pair of circular through holes 402 facing horizontally towards the fixed plate 100 are opened at both ends of the strip plate 400, and a pair of telescopic cylinders 800 are fixed on the side of the strip plate 400 close to the fixed plate 100. The telescopic cylinders 800 correspond to the circular through holes 402 one by one, and the telescopic cylinders 800 are placed coaxially with the corresponding circular through holes 402. The driving rod at the output end of the telescopic cylinder 800 passes through the circular through hole 402 and is fixedly connected to the rectangular frame 700; the rectangular frame 700 is driven by the telescopic cylinder 800 to automatically move away from or close to the strip plate 400.
[0046] In order to facilitate the rotation of the screw 300 and automatically adjust the tightness of the wound closed loop, the upper end of the fixing plate 100 is rotatably connected to a turning handle 301 placed coaxially with the screw 300, and the lower end of the turning handle 301 is fixedly connected to the screw 300; by rotating the turning handle 301, the purpose of facilitating the rotation of the screw 300 is achieved.
[0047] A hook patch 900 of Velcro is fixed on the side wall of any strap 600 away from the side of the strip plate 400 and away from the end of the fixed plate 100, and a suede patch 901 of Velcro is fixed on the side wall of the other strap 600 close to the side of the strip plate 400 and away from the end of the fixed plate 100; the hook patch 900 and the suede patch 901 can be coordinated to facilitate the adhesion and fixation of the two straps 600 away from the end of the fixed plate 100.
[0048] The hook patch 900 and the velvet patch 901 are both arranged in a long strip shape along the axis direction of the corresponding strap 600, so as to facilitate tying the strap 600 around the waist of patients of different body shapes.
