[0036] It should be noted that the embodiments in the utility model and the features in the embodiments can be combined with each other without conflict.

[0037] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," and "back," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0038] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0039] This embodiment relates to a skin wound stapler, such as... Figure 1 As shown, it includes a locking bar 1, which is connected to a locking seat 2. The locking seat 2 is provided with an inclined elastic tongue 3. The locking seat 2 is provided with a locking hole 201 through which the locking bar 1 can pass and a first limiting part 202. The locking bar 1 and the elastic tongue 3 engage with each other.

[0040] The locking bar 1 is fixedly connected to the outside of the locking seat 2. The locking bar 1 has a toothed groove 101 along its length. The elastic tongue 3 has a ratchet part 301 and a handle 302. The toothed groove 101 engages with the ratchet part 301. The locking hole 201 is located at the edge of the ratchet part 301 of the elastic tongue 3. The first limiting part 202 is located on the back side of the ratchet part 301. The locking seat 2 is connected to a second base plate 5.

[0041] The second substrate 5 is located at the bottom of the locking seat 2; the locking strip 1 on one locking seat 2 is inserted into the locking hole 201 of the other locking seat 2; the bottom of the second substrate 5 is provided with an adhesive layer, specifically, the adhesive layer can be tape or other materials that can adhere to the skin and are not easy to fall off.

[0042] The elastic tongue 3 can be disengaged from the tooth groove 101 of the locking bar 1 by pressing the handle 302, thereby adjusting the spacing.

[0043] In this embodiment, when in use, the two second substrates 5 are respectively attached to the skin on both sides of the wound; since the groove 101 and the ratchet 301 are engaged, the two locking strips 1 are pulled, and the skin on both sides of the wound is gradually pulled together to achieve wound anastomosis; the first limiting part 202 can limit the movement of the locking strips 1 to ensure the accuracy of the operation.

[0044] The skin wound stapler using the above-described implementation scheme effectively solves the problem of the inability to reverse adjust the spacing in existing technologies. During wound anastomosis, if medical personnel apply excessive force, causing the wound to be pulled too close, simply press the handle 302 on the elastic tongue 3 to deform the elastic tongue 3, disengaging the ratchet 301 from the groove 101. At this point, the locking strip 1 can be easily pulled out, increasing the wound spacing and achieving reverse adjustment. After adjustment, release the handle 302, the elastic tongue 3 returns to its original shape, and the ratchet 301 re-engages with the groove 101, fixing the adjusted spacing. This design avoids the need to remove the entire stapler due to excessive force, thus effectively preventing secondary damage to the wound and improving the safety and flexibility of wound anastomosis. Example

[0045] This embodiment relates to a skin wound stapler, such as... Figure 2 As shown, it includes a locking bar 1, which is connected to a locking seat 2. The locking seat 2 is provided with an inclined elastic tongue 3. The locking seat 2 is provided with a locking hole 201 through which the locking bar 1 can pass and a first limiting part 202. The locking bar 1 and the elastic tongue 3 engage with each other.

[0046] The locking bar 1 is fixedly connected to the outside of the locking seat 2. The locking bar 1 has a toothed groove 101 along its length. The elastic tongue 3 has a ratchet part 301 and a handle 302. The toothed groove 101 engages with the ratchet part 301. The locking hole 201 is located at the edge of the ratchet part 301 of the elastic tongue 3. The first limiting part 202 is located on the back side of the ratchet part 301. The locking seat 2 is connected to a second base plate 5.

[0047] The locking seat 2 is also provided with a second limiting part 203, which is disposed opposite to the first limiting part 202.

[0048] The locking strip 1 is fixedly connected to the outside of the locking seat 2, and the second base plate 5 is located on the side of the locking seat 2; the locking strip 1 on one locking seat 2 is inserted into the locking hole 201 of another locking seat 2, the inner side of the second limiting part 203 slides in contact with the side of the locking strip 1 facing away from the tooth groove 101, and the bottom of the second base plate 5 has an adhesive layer.

[0049] The elastic tongue 3 can be disengaged from the tooth groove 101 of the locking bar 1 by pressing the handle 302, thereby adjusting the spacing.

[0050] In this embodiment, two second substrates 5 are attached to the skin on both sides of the wound. As the groove 101 and the ratchet 301 mesh, pulling the two locking strips 1 gradually pulls the skin on both sides of the wound together, achieving wound anastomosis. When the locking strip 1 is pulled, the second limiting part 203 and the first limiting part 202 work together to more accurately limit and guide the locking strip 1, ensuring that the locking strip 1 is pulled smoothly and accurately, further improving the accuracy and stability of wound anastomosis.

[0051] The skin wound stapler using the above-described embodiment effectively solves the problem of the inability to reverse adjust the spacing in existing technologies. When it is necessary to adjust the wound spacing, press the handle 302 of the elastic tongue 3 to disengage the ratchet 301 from the tooth groove 101. Due to the presence of the second limiting part 203, the locking bar 1 can maintain a more stable movement trajectory during withdrawal or insertion, avoiding deviation or wobbling, making the spacing adjustment operation more precise. After adjustment, release the handle 302 to restore the engagement state and fix the spacing. This design not only solves the problem of the inability to reverse adjust the spacing in traditional staplers, but also further improves the accuracy and safety of the adjustment process, reducing the potential risks to the wound caused by improper adjustment.

The locking bar 1 and the elastic tongue 3 engage with each other.

[0053] The locking bar 1 is fixedly connected to the outside of the locking seat 2. The locking bar 1 has a toothed groove 101 along its length. The elastic tongue 3 has a ratchet part 301 and a handle 302. The toothed groove 101 engages with the ratchet part 301. The locking hole 201 is located at the edge of the ratchet part 301 of the elastic tongue 3. The first limiting part 202 is located on the back side of the ratchet part 301. The locking seat 2 is connected to a second base plate 5.

[0054] The locking seat 2 is also provided with a second limiting part 203, which is disposed opposite to the first limiting part 202.

[0055] A stop 2021 is provided on the inner side of the second limiting part 203.

[0056] The locking strip 1 is fixedly connected to the outside of the locking seat 2, and the second base plate 5 is located on the side of the locking seat 2; the locking strip 1 on one locking seat 2 is inserted into the locking hole 201 of the other locking seat 2, and the stop block 2021 slides in contact with the side of the locking strip 1 facing away from the tooth groove 101; the bottom of the second base plate 5 has an adhesive layer.

[0057] The elastic tongue 3 can be disengaged from the tooth groove 101 of the locking bar 1 by pressing the handle 302, thereby adjusting the spacing.

[0058] In this embodiment, during the pulling of the locking bar 1, the stop block 2021 slides into contact with the side of the locking bar 1 facing away from the tooth groove 101, which better ensures the accurate engagement of the tooth groove 101 and the ratchet part 301, and improves the reliability of wound anastomosis. Example
