Technical Field

[0001] This invention relates to the field of skin suturing practice technology, specifically a basic suturing practice device. Background Technology

[0002] Skin suturing is a fundamental surgical technique that involves joining cut or ruptured skin tissue to restore its function and promote healing. There are various types of skin suturing, mainly divided into three categories: simple suturing, inversion suturing, and eversion suturing. Each category can be further divided into interrupted and continuous types.

[0003] In real life, medical staff usually practice suturing using simulated skin practice modules. The practice modules are set up as square boards. Square simulation modules cannot simulate wounds on the human limbs, which greatly limits their use. This kind of suturing practice cannot be truly applied to the complexity and diversity of clinical work. Summary of the Invention

[0026] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0027] like Figures 1-6 As shown, the basic suturing practice device of the present invention includes a workbench 1 and a training module 2. The bottom end of the workbench 1 is fixedly connected to a symmetrically arranged first support block 3. The two first support blocks 3 are rotatably connected to a first lead screw 4. A moving plate 5 is threadedly connected to the first lead screw 4. An active rack 6 is fixedly connected to the top end of the moving plate 5.

[0028] The workbench 1 is rotatably connected to a second lead screw 7, and a movable seat 8 is threaded onto the second lead screw 7. A pressing rod 9 is fixedly connected to the top of the movable seat 8, and symmetrically arranged passage slots 10 are provided on the bottom wall of the workbench 1.

[0029] The bottom end of the workbench 1 is fixedly connected to a plurality of symmetrically arranged second support blocks 11, the plurality of second support blocks 11 being in a state of pairwise correspondence, and a rotating rod 12 is rotatably connected between each pair of corresponding second support blocks 11. A driven gear 13 is fixedly connected at the middle position of each of the plurality of rotating rods 12, and an extrusion block 14 is fixedly connected to both ends of each of the plurality of rotating rods 12. An extrusion groove 15 is opened on each of the plurality of extrusion blocks 14.

[0030] The workbench 1 is internally fixedly connected to a plurality of symmetrically arranged mounting brackets 16. Each mounting bracket 16 has a moving groove 17. Each mounting bracket 16 is internally fixedly connected to a crossbar 18. Each crossbar 18 is slidably connected to a connecting block 19. Each connecting block 19 is fixedly connected to a pressure-bearing rod 20 at a position corresponding to the moving groove 17. Each connecting block 19 is fixedly connected to a vertical rod 21. Each vertical rod 21 is slidably connected to a lifting block 22. Each lifting block 22 is fixedly connected to a spring 23 at its top. Each lifting block 22 is fixedly connected to a round rod 24 on its opposite side. The round rods 24 are in a pairwise correspondence. Each pair of corresponding round rods 24 is fixedly connected to a lifting rod 25.

[0031] Specifically, the first support blocks 3 are all fixedly connected with symmetrically arranged first guide rods 26, and the first guide rods 26 are all slidably connected to the moving plate 5. The first screw 4 is provided with a first hand crank 27 on its side end, and the first guide rods 26 facilitate the movement and guidance of the moving plate 5.

[0032] Specifically, the workbench 1 is fixedly connected with symmetrically arranged second guide rods 28, and the second guide rods 28 are slidably connected to the movable seat 8. The second screw 7 is provided with a second hand crank 29 through the side wall of the workbench 1. The second guide rods 28 facilitate the movement and guidance of the movable seat 8.

[0033] Specifically, the active rack 6 is located at the bottom end of one of the driven gears 13, and the active rack 6 is meshed with the corresponding driven gear 13, so that the active rack 6 can drive the driven gear 13 to rotate.

[0034] Specifically, one end of each pressure rod 20 passes through the moving groove 17, the top of each extrusion block 14 passes through the passage groove 10, and one end of each pressure rod 20 is located inside the extrusion groove 15, which facilitates the movement of the pressure rod 20.

[0035] Specifically, the vertical rods 21 are all located in the hollow position of the springs 23, and the top of the springs 23 are all in contact with the inner wall of the worktable 1.

[0036] Specifically, all the lifting rods 25 are located inside the worktable 1, and all the lifting rods 25 are elliptical in shape.

[0037] Specifically, the bottom of the workbench 1 is fixedly connected to symmetrically arranged support rods 30, and the bottom of each support rod 30 is fixedly connected to a suction cup 31. The top wall of the workbench 1 is provided with a through groove 32. The training module 2 is fixedly connected to the top of the workbench 1 by bolts. The suction cup 31 facilitates fixing the position of the workbench 1.

[0038] In use, the entire workbench 1 can be fixed to a certain part of the table using suction cup 31. Then, the second screw 7 is rotated by the second hand crank 29. The rotation of the second screw 7 will drive the moving seat 8 to move. The second guide rod 28 guides the movement of the moving seat 8. The movement of the moving seat 8 will drive the squeezing rod 9 to move towards the lifting rod 25. The side wall of the squeezing rod 9 will then abut against the lifting rod 25. At this time, the moving squeezing rod 9 will squeeze the lifting rod 25 upward. The lifting rod 25 is now located at the bottom center of the wound in training module 2. The upward movement of the lifting rod 25 will drive the round rod 24 and the lifting block 22 to move together. The moving lifting block 22 will squeeze and contract the spring 23. The vertical rod 21 guides the movement of the lifting block 22. At this time, the lifting rod 25 will move upward and push towards the center of the wound in training module 2, thus changing the center of the wound in training module 2 into an arc shape. The arc-shaped wound conforms to the shape of human limbs. At this time, medical staff can perform basic suturing practice on the wound in training module 2.

[0039] When it is necessary to move the lifting rod 25 to the center of the wound on the offset training module 2, the first lead screw 4 can be rotated by turning the first hand crank 27. The rotation of the first lead screw 4 will drive the moving plate 5 and the active rack 6 to move. The first guide rod 26 guides the movement of the moving plate 5. The movement of the active rack 6 will drive the corresponding driven gear 13 to rotate. The rotation of the driven gear 13 will drive the rotating rod 12 to rotate. The rotation of the rotating rod 12 will drive the two extrusion blocks 14 to rotate together. The rotation of the extrusion blocks 14 will cause the extrusion groove 15 to extrude pressure on the pressure rod 20. The pressure rod 20 will move in the direction of the rotation of the extrusion block 14 when it is extruded. The movement of the pressure rod 20 will drive the connecting block 19 to move. This will cause the vertical rod 21, lifting block 22, spring 23, round rod 24 and lifting rod 25 to move together, while the horizontal rod 18 is the moving guide for the connecting block 19. The movement of the lifting rod 25 will offset the center position of the bottom end of the training module 2. At this time, the lifting rod 25 corresponds to the side position of the bottom end of the wound on the training module 2. Then, the squeezing rod 9 will squeeze the lifting rod 25 upward, and the lifting rod 25 will squeeze the wound on the training module 2 into another shape. It can be adjusted according to the actual use needs. After the first row of wounds on the training module 2 is used up, the active rack 6 can be moved to the corresponding position of the other driven gears 13. The operation is the same. When replacing the training module 2, the bolt can be removed for replacement.
