[0031] In some embodiments, the humidifying and heating structure 2 is annular and is disposed between the two open ends of the protective tube 1. The humidifying and heating structure 2 includes a humidifying channel 21 and a heating channel 22, and the humidifying channel 21 and the heating channel 22 are isolated from each other. The humidifying channel 21 extends along the circumference of the humidifying and heating structure 2. A plurality of humidifying holes are formed on the humidifying and heating structure 2. The humidifying holes are connected to the humidifying channel 21. The humidifying channel 21 is connected to the inner cavity of the protective tube 1 through the humidifying holes. The humidifying liquid in the humidifying channel 21 can flow out through the humidifying holes. An injection hole is provided on the humidifying and heating structure 2. The injection hole is used to connect the liquid supply pipe to inject the humidifying liquid into the humidifying channel 21. The humidifying liquid can be, for example, physiological saline. The heating channel 22 extends along the circumference of the humidifying and heating structure 2. A heating component 221 is provided in the heating channel 22. The heating component 221 is used to heat the humidifying liquid and the inner and outer spaces of the protective tube 1.

[0032] In this embodiment, if Figure 2 As shown, the humidifying and heating structure 2 includes an inner wall layer 23, an interlayer 24 and an outer wall layer 25 which are overlapped, a humidifying channel 21 is formed between the inner wall layer 23 and the interlayer 24, and humidifying holes are formed on the inner wall layer 23. A heating channel 22 is formed between the outer wall layer 25 and the interlayer 24, that is, the humidifying channel 21 and the heating channel 22 are overlapped, the humidifying channel 21 is located on the radial inner side, and the heating channel 22 is located on the radial outer side. The heating component 221 in the heating channel 22 can heat the humidifying liquid in the humidifying channel 21. In addition, the heating component 221 can also heat the tissue outside the protective tube 1 to a certain extent.

[0033] In some embodiments, the exposed tissue protection device for laparotomy further comprises a fluid supply component, such as Figure 3 As shown, the liquid supply assembly includes a liquid storage part 31 and a liquid supply tube 32. One end of the liquid supply tube 32 is connected to the liquid storage part 31, and the other end is connected to the injection hole on the humidification and heating structure 2. Physiological saline is contained in the liquid storage part 31. Optionally, a speed regulating structure 33 is provided on the liquid supply tube 32 to control the flow rate of the liquid in the liquid supply tube 32. For example, the liquid supply tube 32 can be selected from an infusion set, and the speed regulating valve on the infusion set constitutes the speed regulating structure 33, which can adjust the liquid supply speed.

[0034] Optionally, the injection hole is connected to a control valve 211, which is used to connect to the liquid supply pipe 32. In some embodiments, the control valve 211 and the speed regulating structure 33 can be set at the same time to more accurately control the flow rate of the moisturizing liquid, or either one of them can be selected, which can also play the role of controlling the flow rate.

[0035] In this embodiment, the control valve 211 is a three-way valve, the first port of the three-way valve is connected to the injection hole, the second port of the three-way valve is connected to the liquid supply pipe 32, and the third port of the three-way valve constitutes a liquid discharge port. The third port can be controlled to open and close independently. The third port is closed when in use. After use, the third port is opened to quickly discharge the remaining humidifying liquid in the humidification channel 21 through the third port.

[0036] In some embodiments, the heating component 221 includes a heating wire, and a power supply interface is provided on the humidifying and heating structure 2. The heating wire is electrically connected to the power supply interface, and the power supply interface is used to connect to an external power source. Optionally, the heating temperature of the heating wire is 35°C-40°C.

[0037] In some embodiments, both open ends of the protective tube 1 are provided with support rings 11, which are elastic structures and provide elastic support for the open ends. The provision of the support rings 11 facilitates the placement of the protective tube 1 into the abdominal cavity, and can play a certain blocking and supporting role on the internal tissues of the abdominal cavity through elastic support force, ensuring that there is enough space and surgical field for the operation. Optionally, the support rings 11 are made of medical metal materials, have a certain elasticity, and are easily elastically deformed under the action of external forces.

[0038] In some embodiments, the side wall of the protective tube 1 includes a first section 12 and a second section 13, both of which are cylindrical structures, and the humidification and heating structure 2 is connected between the first section 12 and the second section 13, that is, the side wall of the protective tube 1 is composed of the first end, the second end and the humidification and heating structure 2. In this embodiment, the first section 12, the second section 13 and the humidification and heating structure 2 are all made of flexible materials, such as medical rubber materials with certain elasticity, which are easy to elastically deform and have certain flexibility, and can effectively avoid damage to the internal tissues of the abdominal cavity.

[0039] In some embodiments, the diameter of the humidifying and heating structure 2 is larger than the diameter of the first section 12 and the second section 13, so that the protective tube 1 is formed into a barrel shape with a thick middle and thin ends, which can increase the humidification and heating range of the humidifying and heating structure 2, improve the humidification and heating effects, and also increase the internal space of the protective tube 1. In addition, the first section 12 and the second section 13 have smaller diameters and are convenient for being placed in the abdominal cavity.

[0040] The method for using the exposed tissue protection device for laparotomy provided by the utility model comprises:

[0041] During laparotomy, one end of the protective tube 1 is inserted into the abdominal cavity, and the exposed tissue is extended from the lower end of the protective tube 1 into the protective tube 1, and the humidification and heating structure is located in the skin layer. The liquid supply pipe 32 is connected to the control valve 211, and the external power supply is connected to the power supply interface to start heating. Then the control valve 211 is opened to start supplying liquid into the humidification channel 21. When the humidification liquid flows in the humidification channel 21, it is heated by the heating component 221 and then flows out through the humidification hole, which can not only moisturize the tissue but also heat it, and the heating component 221 can also directly heat and keep the tissue in the abdominal cavity warm.
