[0029] The technical solutions of the preferred embodiments of the present application will be further described in detail below with reference to the drawings.

[0030] Embodiment 1

[0031] As Figs. 1-3As shown, the utility model discloses a kind of wound surface paste after suture for transumbilical single-hole laparoscopic surgery of preferred embodiment 1, including transparent dressing 10 can be pasted on skin, can adopt 3M transparent dressing or similar product, yarn or gauze ball or conformal cotton ball is made into wound extrusion block 20 in the middle lower portion of the dressing, under the action of negative pressure, to the seamless filling compression wound surface of various shapes of umbilical hole.In the transparent dressing 10 below, the release paper (for known technology, not shown in the figure) is attached to the adhesive surface of the transparent dressing and covers the wound extrusion block 20.In the upper portion of the wound extrusion block 20, airway blocking switch 30 that can be passed through injection needle, air under transparent dressing is extracted to form negative pressure, injection needle is extracted and can be closed to maintain negative pressure, the function of this airway blocking switch 30 is to realize one-way ventilation, using injection needle to extract pressure inside dressing, so that umbilical hole under transparent dressing maintains negative pressure state, but gas cannot enter umbilical hole and dressing reversely, so that umbilical hole under dressing always maintains negative pressure compression wound surface state.

[0032] As embodiment 1, the preferred airway blocking switch 30 is a cylindrical solid silica gel plunger, which is fixed on the transparent dressing and penetrates the transparent dressing, can be penetrated by injection needle, and can be automatically closed after injection needle is extracted, and does not need to be very large, 2mm diameter is feasible. It can also be an elastic material such as rubber plug.

[0033] When using the wound surface paste of embodiment 1, first tear off the release paper, place the wound extrusion block 20 into the patient's navel, paste the transparent dressing on the skin 50 around the navel, penetrate the airway blocking switch (silica gel or rubber plunger) with the injection needle, extract the air under the transparent dressing to form negative pressure, and the needle hole of the airway blocking switch 30 can be automatically closed after the injection needle is extracted to maintain negative pressure. In this way, the transparent dressing is like a negative pressure suction disc around the navel, and the wound extrusion block 20 will tightly adhere to the navel to apply pressure to the sutured wound surface, press the wound and stop bleeding. According to different patients, different umbilical hole shapes and different surgical wounds, the negative pressure pressure can be adjusted.

[0034] Embodiment 2

[0035] As Figs. 4-5 shown, another preferred wound surface paste for transumbilical single-hole laparoscopic surgery after suture of embodiment 2 of the utility model, similar to embodiment 1, also includes transparent dressing 10 that can be pasted on skin, wound extrusion block 20, airway blocking switch 30 that penetrates the transparent dressing, and release paper.

[0036] Unlike Example 1, the airway blocking switch 30 is an annular switch with a through hole 31. An openable lid 40 covers the annular switch. A sealing plug 41 protrudes from the center of the lid and fits within the through hole 31. A connecting piece 42 extends from the side of the annular switch and connects to the upper surface of the transparent dressing 10 (see diagram). The airway blocking switch 30 and lid 40 can be made of silicone or rubber, but may also be made of other elastic materials.

[0037] To use the wound dressing of Example 2, remove the release paper, place the wound compression block 20 against the patient's navel, and apply the transparent dressing to the skin around the navel 50. Open the lid 40, insert a syringe through the through-hole 31, and evacuate the air under the transparent dressing, creating a negative pressure. Then, close the lid 40 to maintain the negative pressure. The transparent dressing acts like a negative pressure suction cup around the navel, and the wound compression block 20 adheres to the navel, applying pressure to the wound surface, closing the wound, stopping bleeding, and reducing oozing blood.

[0038] Example 3

[0039] like Figs. 6-7 As shown, another preferred embodiment of the utility model is a wound dressing for suturing after single-port laparoscopic surgery through the umbilicus. Similar to the embodiment 1, it also includes a transparent dressing 10 that can be adhered to the skin, a wound squeezing block 20, an airway blocking switch 30, and release paper.

[0040] The main difference from Example 1 is that the airway blocking switch 30 does not pass through the transparent dressing, but is instead a sealing adhesive patch affixed to the surface of the transparent dressing. The transparent dressing 10 has an opening 11, or an opening left by a needle passing through the transparent dressing, and the adhesive patch is removably affixed to the opening. The sealing adhesive patch is preferably a plastic adhesive patch with a non-stick edge 32 that is not attached to the transparent dressing to facilitate removal.

[0041] To use the wound dressing of Example 2, remove the release paper, place the wound compression block 20 under the patient's navel, apply the transparent dressing to the skin around the navel 50, pull up the non-stick edge 32, partially remove the sealing adhesive block, and insert an injection needle through the opening 11 or directly pierce the transparent dressing below the adhesive block to extract the air under the transparent dressing, creating negative pressure. The adhesive block is then reapplied to maintain the negative pressure. The transparent dressing acts like a negative pressure suction cup around the navel, and the wound compression block 20 adheres to the navel to apply pressure to the wound surface, thereby closing the wound, stopping bleeding, and reducing oozing blood.

[0042] Example 4

[0043] Similar to example 1, also included are a transparent dressing 10 that can be adhered to the skin, a wound expression block 20, an airway occlusion switch 30 that passes through the transparent dressing, and a release paper. Unlike example 1, the airway occlusion switch 30 is a one-way valve, similar to the solid silicone plunger of example 1, that is affixed to and passes through the transparent dressing. The one-way valve can be any commercially available medical one-way valve.
