[0023] The technical solution provided in the present application ensures the tension in the vertical and horizontal directions of the wound by setting oblique braces and vertical braces, which can improve the effect of wound healing without leaving scars and improve the treatment effect.

[0024] Optionally, the acute angle α is 10° to 60°.

[0025] Optionally, a handle portion 2012 is provided at the other end of each pull strip, and the handle portion 2012 is used to cooperate with the multi-stage serrations and the locking teeth after being pulled, so that the distance between the two matching strips is shortened.

[0026] In a second aspect, an anastomosis module is provided, the anastomosis module comprising: two pull rods and two anastomosis openings, wherein one end of the two pull rods are fixedly connected and the angle between the two pull rods is an acute angle;

[0027] The other ends of the two pull rods can pass through the corresponding anastomotic openings respectively; multiple levels of saw teeth are arranged between the two ends of each pull rod;

[0028] Each anastomotic opening has a toothed portion, each pull strip passes through the toothed portion of the corresponding anastomotic opening, and a toothed piece matched with the multi-stage saw teeth is arranged in the toothed portion.

[0029] In order to better illustrate the effect of the present application scheme, clinical trial data are given as examples here.

[0030] Experimental design: 30 elderly people who were undergoing rehabilitation in our hospital were selected. They were required to have complete lower limb mobility and relatively consistent lower limb mobility, and moderate activity. Two different fitting methods, horizontal and vertical, were used for testing at the knee joint. The left and right knees of the same elderly were respectively fitted with common parallel-fit products on the market (such as Figure 5 The product structure shown) and the product with oblique pulling force of the present application (such as Figure 1 The effective adhesion time was finally calculated (the test used an 8CM stapler).

[0031] Principle of the test: For bedridden surgical patients, there is little difference between the two pulling and closing methods. However, for athletes, soldiers, firefighters or patients with high-tension wounds, the two closing methods may have advantages and disadvantages. Therefore, we selected patients with symmetrical and normal activities of both lower limbs in the rehabilitation department. Their activity volume is uniform and moderate as prescribed by the department. The knee joint was selected because it is of moderate size and has one of the largest range of motion among all joints. The durability of the skin stapler in different directions was tested using both longitudinal and transverse methods.

[0032] Purpose of the experiment: By using two different skin staplers on the left and right knees of the same person, under the same usage environment and usage intensity, to compare which skin stapler provides stronger tension for the skin and has a longer usage time.

[0033] Test standard: Use a dynamometer to apply 0.8N of force to each drawstring in the direction of tension at regular intervals every day. When 30% of the drawstring bases fall off, or three drawstring bases fall off consecutively, the use time is judged to have expired.

[0034] Table 1: Lateral fit at the knee joint (perpendicular to the leg)

[0035]

[0036] Note: 2 people withdrew from the trial due to other reasons

[0037] Table 2: Longitudinal fit at the knee joint (0 degrees to the leg at the knee joint)

[0038]

[0039]

[0040] Note: 4 people withdrew from the trial due to illness

[0041] From the data in Table 1 and Table 2, it can be analyzed that the pulling force and average use time provided by Product 1 are significantly higher than those of Product 2. The advantage of Product 1 is more obvious when the wound is in the same direction as the movement. Therefore, Product 1 can provide more reliable pulling force after ordinary patients wake up from anesthesia and can move. In various track and field games, ball games and wars, when minor bleeding injuries occur, this product can be used for emergency treatment and provide sufficient tension to ensure the user's ability to continue to move. When major injuries and heavy bleeding occur on the battlefield, it can also be used as an emergency treatment to temporarily close the wound to reduce bleeding and buy time to evacuate the battlefield.
