Description

Technical Field

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

[0002] In surgical procedures, wounds are usually treated by suturing. However, sutured wounds can leave unsightly scars. Therefore, to reduce scarring after suturing, sutureless devices are often used to treat wounds and promote healing.

[0003] Existing sutureless wound closure devices use a closed structure design between the pull cord and the connecting seat, which makes it difficult to easily remove the pull cord from the side of the connecting seat. This structure makes it difficult to make secondary adjustments after tightening, especially when fine-tuning the tension or changing the dressing, making the operation steps cumbersome.

[0004] Therefore, given that the existing sutureless wound closure device has a closed structure between the pull cord and the connecting seat, making it difficult to adjust after tightening and inconvenient to operate, there is an urgent need to design a new type of sutureless wound closure device. Utility Model Content

[0005] To overcome the problem that existing sutureless wound closure devices have a closed structure between the pull cord and the connecting seat, making it difficult to adjust after tightening and inconvenient to operate.

[0006] The technical solution of this utility model is as follows: a sutureless wound closure device, including an adhesive paper; it also includes adhesive gauze, a positioning seat, a pull rod, a locking block and a side slot. The upper surface of the adhesive paper is provided with two symmetrical adhesive gauzes. The upper surface of each adhesive gauze is provided with two symmetrical positioning seats. A pull rod is connected to one side of the positioning seat. Several locking blocks are installed on the outer surface of the pull rod at equal intervals. A side slot is opened at one end of the positioning seat, and the locking blocks engage with the side slot.

[0007] Preferably, by setting a positioning seat, each pull rod connected to the positioning seat can be inserted laterally into the side slot of another positioning seat symmetrical to it. The slot of the side slot can engage with the locking block on the outer surface of the pull rod, so that the pull rod can only be pulled in one direction and will not retract. When it is necessary to disassemble, the pull rod can be moved to the side, so that the locking block slides out of the side slot. The operation is simple and the locking effect is good. This solves the problem that the existing sutureless wound closure device has a closed structure between the pull rope and the connecting seat, and the pull rope is not easy to remove from the side of the connecting seat, which makes it difficult to adjust after tightening and inconvenient to operate.

[0008] Preferably, a pull block is provided at the end of the pull rod away from the corresponding positioning seat, and the pull block is fixed to the pull rod by welding.

[0009] Preferably, the locking block has a conical structure, and the locking block and the pull rod are integrally injection molded.

[0010] Preferably, a limiting block is machined on the top of the positioning seat corresponding to the position of the side slot, and an arc-shaped protrusion is provided on the bottom of the inner surface of the side slot.

[0011] Preferably, the upper surface of the positioning seat is provided with several glue injection holes, which penetrate the positioning seat.

[0012] Preferably, all four pull blocks are flat rectangular parallelepipeds.

[0013] Preferably, connecting pieces are provided on both the left and right sides of the upper surface of the two adhesive gauzes, with two symmetrical button seats installed on the upper surface of the right connecting piece and two symmetrical push buttons installed on the bottom surface of the right connecting piece.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up positioning seats, the four positioning seats are symmetrically distributed in a matrix. Each pull rod connected to a positioning seat can be inserted into the side slot of another positioning seat symmetrical to its front and rear, thereby linking the four positioning seats together. The locking block on the outer surface of the pull rod will be engaged by the slot of the side slot, so that the pull rod can only be pulled in one direction and will not retract. When it is necessary to disassemble, the pull rod can be moved to the side, so that the locking block slides out of the side slot. The operation is simple and the locking effect is good. This solves the problem that the existing sutureless wound closure device has a closed structure between the pull rope and the connecting seat, and the pull rope is not easy to remove from the side of the connecting seat, which makes it difficult to adjust after tightening and inconvenient to operate.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5 This utility model provides an embodiment of a sutureless wound closure device, including an adhesive paper 1; it also includes adhesive gauze 2, positioning seats 3, pull rods 4, locking blocks 5, and side slots 6. Two symmetrically arranged adhesive gauze sheets 2 are provided on the upper surface of the adhesive paper 1. Two symmetrically arranged positioning seats 3 are provided on the upper surface of each adhesive gauze sheet 2. A pull rod 4 is connected to one side of each positioning seat 3. Several equally spaced locking blocks 5 are installed on the outer surface of the pull rod 4. A side slot 6 is provided at one end of each positioning seat 3. The locking blocks 5 engage with the side slot 6. By setting the positioning seats 3, each pull rod 4 connected to a positioning seat 3 can be inserted laterally into the side slot 6 of the other symmetrically arranged positioning seat 3. The slot of the side slot 6 engages with the locking blocks 5 on the outer surface of the pull rod 4, so that the pull rod 4 can only be pulled in one direction without retraction. When disassembly is required, the pull rod 4 can be moved to the side, allowing the locking blocks 5 to slide out of the side slot 6. The operation is simple, and the locking effect is good.

[0024] Please see Figures 1-3 In this embodiment, a pull block 8 is provided at the end of the pull rod 4 away from the corresponding positioning seat 3. The pull block 8 and the pull rod 4 are fixed by welding. By providing the pull block 8, the user can pull the pull block 8 to drive the pull rod 4 to retract, thereby bringing the two pieces of adhesive gauze 2 closer to each other. The locking block 5 has a conical structure and is integrally injection molded with the pull rod 4. By designing the locking block 5 as a conical structure, when the pull rod 4 is pulled, the inclined side of the locking block 5 can reduce the resistance with one side of the side slot 6. At the same time, the flat structure at its bottom can form a large resistance with the other side of the side slot 6, preventing the pull rod 4 from retracting. The top of the positioning seat 3 is machined with a limiting block 7 at the position corresponding to the side slot 6. The bottom of the inner surface of the side slot 6 is provided with an arc-shaped protrusion. By providing the limiting block 7, the upper end of the locking block 5 can be limited and locked. The arc-shaped protrusion design of the bottom surface of the side slot 6 can play an anti-slip role, preventing the locking block 5 from sliding out of the inside of the side slot 6 on its own.

[0025] Please see Figures 1-5In this embodiment, the upper surface of the positioning seat 3 is provided with several glue injection holes 9, which penetrate the positioning seat 3. By setting the glue injection holes 9, the staff can inject glue into the glue injection holes 9 to fix the positioning seat 3 and the adhesive gauze 2. The four pull blocks 8 are all flat cuboid structures. By making the pull blocks 8 into flat cuboids, it is easier for the user to grip them and pull the pull rod 4 easily. The upper surfaces of the two adhesive gauze 2 are provided with connecting pieces 10 on both the left and right sides. The upper surface of the right connecting piece 10 is equipped with two symmetrical button seats 11, and the bottom surface of the right connecting piece 10 is equipped with two symmetrical press buttons 12. By setting the connecting pieces 10, button seats 11 and press buttons 12, it is easy to splice the whole device according to the size of the wound, improving flexibility.

[0026] During operation, by pulling the lever 8, the user can retract the lever 4, bringing the two adhesive gauze pieces 2 closer together. The conical design of the locking block 5 reduces resistance on one side of the side slot 6 when the lever 4 is pulled, while its flat bottom provides greater resistance on the other side, preventing the lever 4 from retracting. The limiting block 7 provides a locking mechanism for the upper part of the locking block 5. The arc-shaped protrusion on the bottom of the side slot 6 prevents slippage, ensuring the locking block 5 doesn't slide out of the slot. The glue injection hole 9 allows the operator to inject glue, securing the positioning seat 3 to the adhesive gauze 2. The flat rectangular design of the lever 8 facilitates gripping and easy lever 4 pulling. The connecting piece 10, button seat 11, and press button 12 allow for easy assembly of the device according to wound size, increasing flexibility.

[0027] Through the above steps, by setting up positioning seats 3, the four positioning seats 3 are symmetrically distributed in a matrix. Each pull rod 4 connected to the positioning seat 3 can be inserted into the side slot 6 of another positioning seat 3 symmetrical to it, thereby linking the four positioning seats 3 together. The locking block 5 on the outer surface of the pull rod 4 will be engaged by the slot of the side slot 6, so that the pull rod 4 can only be pulled in one direction and will not retract. When it is necessary to disassemble, the pull rod 4 can be moved to the side, so that the locking block 5 slides out of the side slot 6. The operation is simple and the locking effect is good. This solves the problem that the existing non-suture wound closure device has a closed structure between the pull rope and the connecting seat, and the pull rope is not easy to take out from the side of the connecting seat, which makes it difficult to adjust after tightening and inconvenient to operate.
