Figure 1-4As shown, the hook-type skin traction closure device includes an adjusting assembly and a fixing hook device. The adjusting assembly includes a threaded rod 6, a pressure adjusting component 5, a pressure adjusting spring 20, a sliding sleeve 7, and a fixing nut 1. The fixing hook device includes a first fixing hook part 3, a second fixing hook part 17, and a row of hooks 9 sequentially installed on the inner sleeve 4. The first fixing hook part and the second fixing hook part 19 have fixing screw holes 16 on their sides, in which fixing screws 23 are installed to fix the tail of the row of hooks. Specifically, the fixing hook part 3 and the second fixing hook part 17 have fixing screw holes 16 and communicating hook holes. The row of hooks is installed in the hook holes, and fixing screws 21 are installed in the screw holes 16 to fix the row of hooks 9. Figure 3 As shown, the upper end of the fixed hook part has two fixing screw holes 21, in which fixing screws 2 are installed. The fixing screws 2 are threadedly connected to the fixed hook part. The fixing screw holes 16 are connected to the guide holes 15 provided on the fixed hook part. The guide rod 8 in the guide hole can be fixed by screwing in the fixing screws 2.

[0022] The upper part of the fixed hook body 19 has a round hole 14 and two guide holes 15 arranged horizontally. The threaded rod 6 passes through the round hole 14 and is fitted with a fixing nut 1. The fixing nut 1 and the pressure adjusting component 5 are screwed onto the two ends of the threaded rod respectively. The pressure adjusting spring 20 and the sliding sleeve 7 are sequentially sleeved on the threaded rod. The pressure adjusting component 5, the pressure adjusting spring and the sliding sleeve 7 are sequentially pushed and engaged. The inner sleeve 10 and the outer sleeve 4 are fitted on the threaded rod between the sliding sleeve 7 and the fixing nut 1. The two fixed hook devices are slidably sleeved on the inner sleeve 10 through the round hole 14 and are pushed and engaged with the outer sleeve 4 and the fixing nut 1 respectively along the axial direction. The outer sleeve 4 is pushed and engaged with the sliding sleeve 7.

[0023] In this embodiment, the pressure regulating component 5 includes a nut section and a sleeve section. The nut section has an internal thread, and the pressure regulating spring 20 is disposed in the sleeve section and pushes against the inner end face of the nut section. The outer diameter of the sliding sleeve 7 is not greater than the inner diameter of the sleeve section, which can guide the pressure regulating spring 20.

A boss 18 is provided on the outer side of the connecting sleeve.

[0028] The threaded rod can be fully threaded or partially threaded and partially unthreaded. When the threaded rod is partially threaded and partially unthreaded, the skin tension closure device with the injection hole does not have an inner sleeve. The unthreaded part directly slides into the round hole provided on the first and second fixed hook parts.

[0029] Example 2, as Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that the circular holes 14 are symmetrically arranged on both sides of the fixed hook body part 1 3 and the fixed hook body part 2 19, respectively. A threaded rod 6 is installed in each circular hole. The fixed nut 1 and the pressure adjusting component 5 are screwed onto both ends of the threaded rod 6. The pressure adjusting spring 20 and the sliding sleeve 7 are sequentially sleeved on the threaded rod 6. The pressure adjusting component 5, the pressure adjusting spring 20, and the sliding sleeve 7 are sequentially pushed and engaged. An inner sleeve 10 and an outer sleeve 4 are fitted onto the threaded rod between the sliding sleeve 7 and the fixed nut 1. The two fixed hook devices are slidably fitted onto the inner sleeve 10 through the circular holes 14, and are respectively pushed and engaged axially with the outer sleeve 4 and the fixed nut 1. The outer sleeve 4 is pushed and engaged with the sliding sleeve 7. In this embodiment, tension adjustment is achieved only through two sets of adjusting components. During use, the tension on the skin can be dispersed, reducing stress concentration on the skin and promoting wound healing.
