[0005] In use, the simulated skin silicone strip is wound between the left and right supports, which are interchangeable when viewed from different sides. The winding sequence of the simulated skin silicone strip is: winding roller and auxiliary roller on the left support, and auxiliary roller and winding roller on the right support. Adjust the appropriate spacing between the left and right supports, keeping the simulated skin silicone strip horizontal between the two auxiliary rollers. Use pressure plates to press both ends of the simulated skin silicone strip firmly onto the auxiliary rollers. Adjust the lifting top plate to rise, taut the simulated skin silicone strip, and then cut it open along the groove to form a simulated wound for suturing practice. After one practice session, roll the simulated skin silicone strip to one side to begin the next session. This device can create simulated wounds with different tension levels for suturing practice as needed, offering high simulation accuracy, good practice results, and high material utilization.

[0006] Preferably, the lifting top plate is mounted on the left support, and the left support is provided with a vertical adjustment groove corresponding to the lifting top plate. The lifting top plate is slidably mounted in the vertical adjustment groove, and a locking bolt for locking the lifting top plate is provided on one side of the vertical adjustment groove.

[0007] Preferably, the top surface of the lifting platform is arc-shaped, with a groove in the middle. The groove is positioned to correspond to the simulated incision, preventing interference during practice.

[0008] Preferably, the left and right supports have adjustable plates on their opposite sides. One adjustable plate has several guide posts, and the other adjustable plate passes through the guide posts. Springs are fitted around the guide posts. An adjusting screw is provided between the two adjustable plates. One end of the adjusting screw is threadedly connected to one of the adjustable plates, and the other end is pressed onto the other adjustable plate using a wrench. The gap between the left and right supports is adjustable, allowing for the most comfortable spacing for different practitioners.

[0009] Preferably, the top of the left and right supports is provided with a top plate, and the top plate is provided with a pressure plate screw, which is pressed on the pressure plate.

[0010] Preferably, at least one of the winding rollers is provided with a rotating handwheel.

[0011] Preferably, the two auxiliary rollers are set at the same height.

[0012] This invention can create simulated wounds with different tension levels as needed for suturing practice, with high simulation accuracy, good practice effect, and high material utilization. Attached Figure Description
