[0002] A wound is a certain amount of damage to the skin caused by external factors, including wounds caused by accidents or human surgical interventions. When treating such wounds, sutures are generally used to pull the skin wounds together and allow the wounds to heal through cell self-repair. In the existing technology, in order to allow patients to reduce the pain caused by sutures and repair scars in the later stage, skin traction equipment is currently available to repair skin wounds. The general skin traction method is to pull the skin on both sides of the wound and bring them closer to each other, but when dealing with irregular wounds, the traction on both sides of the wound may not be applicable to the repair of irregular wounds, affecting the quality of skin repair and healing. Summary of the Invention

DETAILED DESCRIPTION

[0016] In the present invention, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0017] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediary. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0018] Example 1

[0019] Please refer to Figure 1-Figure 2 The present invention proposes a full-thickness skin wound repair traction device, comprising a ring sleeve 1 and an adhesive sheet 2 adsorbed on the skin, the adhesive sheet 2 is connected to the pull strip 3, and the ring sleeve 1 is provided with multiple anti-return components 4 for circular sliding. Each pull strip 3 is connected to a corresponding anti-return component 4, and the pull strip 3 can be pulled to tighten the gap between the adhesive sheet 2 and the ring sleeve 1; in this solution, the adhesive sheet 2 needs to be pasted on the skin around the wound, and then the pull strip 3 is inserted into the anti-return component 4 and tightened, so that all the adhesive sheets 2 gather together and pull the skin closer to each other. The position of the anti-return component 4 relative to the ring sleeve 1 can be changed, so that the tension between the adhesive sheet 2 and the connecting pull strip 3 can always be maintained in the radial direction of the ring sleeve 1, which can avoid the pull strip 3 from crossing or bending, thereby improving stability.

[0020] In the specific implementation manner, reference Figure 1 、 Figure 2 , a ring groove 11 with an opening facing outward is provided in the ring kit 1, and the anti-return component 4 includes a connecting strip 41, a slider 42 and a anti-return part 43. The slider 42 and the anti-return part 43 are connected to the two ends of the connecting strip 41 respectively, and the slider 42 slides in the ring groove 11, and the pull strip 3 is connected to the anti-return part 43; in this solution, the connecting strip 41 is made of plastic material, and the connecting strip 41 can be bent. In this application, when the slider 42 slides in the ring groove 11, it can be separated from the slider 42 on the adjacent side by a certain interval. At this time, the anti-return part 43 will also change its position with the slider 42, thereby responding to the requirements of different positions of the anti-return part 43, so that the anti-return part 43 can cooperate with the pull strip 3 to pull the adhesive sheet 2.

[0021] In the specific implementation manner, reference Figure 1 、 Figure 2A mounting opening 12 is provided above the ring suite 1 to facilitate the installation of the slider 42 into the ring groove 11. The ring suite 1 is provided with a cover body 13 that can be flipped over at the mounting opening 12. The ring suite 1 is located on one side of the mounting opening 12 and connected to a limiting belt 14. A column 15 is provided on the other side of the mounting opening 12. The limiting belt 14 passes over the mounting opening 12 and is connected to the column 15. In this solution, each slider 42 corresponds to a pull strip 3, and its slider 42 can be installed in the ring groove 11 through the mounting opening 12, and then sealed by the flippable cover body 13. The top of the cover body 13 is restricted by the limiting belt 14 to prevent the cover body 13 from flipping over and causing the slider 42 to fall off.

[0022] In the specific implementation manner, reference Figure 1 、 Figure 2 The anti-return member 43 is provided with a socket 431 that is transparent at both ends, and a swingable fastener 432 is installed in the socket 431. A tooth key 31 is provided on one side of the pull rod 3. When the pull rod 3 is inserted from the socket 431, the fastener 432 engages with one of the tooth keys 31; in this solution, when the pull rod 3 is inserted into the socket, its tooth key 31 will push the fastener 432 to bounce inward, and when the pull rod 3 is pulled in the reverse direction, its fastener 432 will move closer to the tooth key 31 to prevent the tooth key 31 from moving in the reverse direction; its fastener 432 has a connecting portion, and the tail end of its connecting portion is located at the entrance of the socket 431 for connection.

[0023] In the specific implementation manner, reference Figure 1 、 Figure 2 There is a gap between the two sides of the fastener 432 and the two sides of the socket 431, and the pull strip 3 is provided with guide strips 32 on both sides of the tooth key 31. When the pull strip 3 is inserted into the socket 431, the guide strip 32 is located in the gap between the fastener 432 and the side of the socket 431 and slides; in this solution, the guide strip 32 provided on the pull strip 3 can facilitate the insertion of the pull strip 3 into the socket 431, and at the same time can avoid the phenomenon of the pull strip 3 being inserted into the socket 431 in reverse, thereby improving convenience.

[0024] In the specific implementation manner, reference Figure 1 、 Figure 2 A connecting piece 33 is provided at one end of the pull strip 3 away from the ring sleeve 1, and the connecting piece 33 is connected to the center of the upper end of the adhesive sheet 2; in this solution, the pull strip 3 can better bear the force of the adhesive sheet 2 through the connecting piece 33.

[0025] Example 2

[0026] refer to Figure 3In this solution, the ring kit 1 includes a shaft body 16 and a limiting piece 17. The two limiting pieces 17 are respectively connected to the two ends of the shaft body 16. The anti-return component 4 includes a connecting strip 41, a rotating piece 44 and a anti-return member 43. The center of the rotating piece 44 has a circular hole 441. Multiple rotating pieces 44 are sleeved on the shaft body 16 through the circular hole 441. The rotating piece 44 is located between the two limiting pieces 17. The rotating piece 44 can be rotated through the shaft body 16, which can reduce the thickness of the ring kit 1.
