[0019] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0020] like Figures 1 to 3 As shown, this utility model provides a disposable surgical irrigation tube. Specifically, before use, this utility model can be sterilized with ethylene oxide to achieve aseptic requirements. This utility model includes an instrument tube 5 with a sealing body 6. Specifically, both the instrument tube 5 and the sealing body 6 are existing technologies, similar to the multi-channel sealing body on a multi-channel single-port abdominal surgical trocar; or the sealing body 6 can be made of medical silicone material that can deform in the prior art, and an instrument channel 61 parallel to the axial line of the sealing body 6 is formed on the sealing body 6. In the initial state, when no surgical instruments are installed in the instrument tube 5, the instrument channel 61 can be sealed by the deformation of the sealing body 6 itself. However, when surgical instruments are installed in the instrument tube 5, such as cameras and joint suture hooks, the surgical instruments can expand the instrument channel 61 as they pass through the sealing body 6. Furthermore, the deformation of the sealing body 6 itself can also cause the sealing body 6 to fit against the surgical instruments, thus sealing the instrument channel 61. In this way, during use, it can prevent the irrigation fluid from flowing out from the instrument channel 61, thereby reducing infection.

[0021] In addition, this utility model also includes an irrigation tube 4 and two fixed protective shells 1 with hollow structures. Specifically, the inner diameter of the irrigation tube 4 can be set to 7 mm and the outer diameter can be set to 9 mm to ensure that the flow rate of the irrigation fluid meets the surgical requirements. One end of the irrigation tube 4 is fixedly connected to an infusion needle 10. In use, the irrigation tube 4 can be connected to a container containing irrigation fluid, such as an infusion bottle or infusion bag, through the infusion needle 10. The other end of the irrigation tube 4 is connected to one of the fixed protective shells 1, and a flow regulator 13 is installed on the irrigation tube 4. The flow regulator 13 is an infusion flow regulator, which can be used to adjust the flow rate of the irrigation fluid in use. Flow rate; The bottom surface of the fixed protective shell 1 is open, and the top surface of the fixed protective shell 1 is fixedly connected to the instrument tube 5. The outer side of each fixed protective shell 1 is also fixedly connected to a drain pipe 2 with a first switch valve 14 and an arc shape. The first switch valve 14 is a two-way switch valve for infusion. The first switch valve 14 can be used to open and close the drainage channel in the drain pipe 2. The end of the drain pipe 2 away from the fixed protective shell 1 is higher than the other end of the drain pipe 2, and the drain pipes 2 on the two fixed protective shells 1 are symmetrically distributed. Specifically, support frames can be set on the fixed protective shells 1 to support the drain pipes 2, and the drain pipes 2 on the two fixed protective shells 1 are distributed in a "butterfly shape".

[0022] Specifically, during use, the irrigation tube 4 can be connected to a container filled with irrigation fluid via the infusion needle 10. Then, the first switch valve 14 is opened to open the drainage channel of the drain tube 2. Subsequently, the bottom opening of the fixing protective shell 1 can be inserted into the two incision positions respectively, and the size of the fixing protective shell 1 is adapted to the size of the incision position. After the bottom of the fixing protective shell 1 is inserted into the incision position, the position of the fixing protective shell 1 can be fixed. The operation method is relatively simple. At this time, the two fixing protective shells 1 are connected, and the irrigation fluid can flow into the fixing protective shell 1 respectively to rinse the incision position. At the same time, surgical instruments can be inserted into the incision position through the instrument tube 5 to perform surgical operations. When the irrigation fluid fills the fixed protective shell 1, it can be discharged outward through the drain pipe 2. By observing the speed at which the irrigation fluid flows out of the drain pipe 2, it is possible to visually determine whether the flow rate of the irrigation fluid meets the surgical requirements. During the operation, the flow rate of the irrigation fluid can be automatically adjusted by the flow regulator 13 according to the surgical needs to ensure that the surgical field is clearly visible, thereby shortening the operation time and reducing the occurrence of intraoperative complications. Secondly, by setting up the fixed protective shell 1, it is also possible to prevent the discharged irrigation fluid from flowing back into the incision site, thereby reducing the chance of infection and ensuring patient safety. In addition, by observing the speed at which the irrigation fluid flows out of the drain pipe 2, it is also possible to determine the pressure in the wound, so as to avoid secondary injury to the patient.

[0023] Furthermore, such as Figure 1 and Figure 3As shown, the bottom of each fixed protective shell 1 is a tapered structure that is wider at the top and narrower at the bottom, which makes it easy to insert the bottom of the fixed protective shell 1 into the cut position.

[0024] The specific arrangement of the flushing pipe 4 connecting to the inner part of the fixed protective shell 1 is as follows: Figures 1 to 3 As shown, each fixed protective shell 1 is fixedly connected to an inlet pipe 3 with a second switching valve 15. The second switching valve 15 is a two-way switching valve for infusion, which can be used to open and close the inlet channel in the inlet pipe 3. The end of the inlet pipe 3 away from the fixed protective shell 1 is fixedly connected to a first connector 16, and the end of the flushing pipe 4 away from the infusion needle 10 is fixedly connected to a second connector 17 that matches the first connector 16. Specifically, after connecting the first connector 16 and the second connector 17, the flushing pipe 4 can be connected to the inside of the fixed protective shell 1 through the inlet pipe 3. In use, when one of the fixed protective shells 1 is connected to the flushing pipe 4, the second switching valve 15 on the other fixed protective shell 1 is in a closed state. In addition, in use, the two fixed protective shells 1 can be connected to the flushing pipe 4 respectively, that is, two sets of flushing pipes 4 are used to flush the two incision positions respectively.

[0025] Furthermore, such as Figure 1 and Figure 3 As shown, the end of the flushing tube 4 away from the fixed protective shell 1 is fixedly connected to the infusion drip tube 7. Specifically, by setting the infusion drip tube 7, the flow rate of the flushing fluid can be kept uniform and air can be prevented from entering. The specific arrangement of the connection between the infusion needle 10 and the flushing tube 4 is as follows: an infusion tube 9 is fixedly connected to the infusion drip tube 7, and the end of the infusion tube 9 away from the infusion drip tube 7 is fixedly connected to the infusion needle 10.

[0026] Furthermore, such as Figure 1 and Figure 3 As shown, the infusion drip tube 7 is equipped with a filter screen 8. Specifically, by setting the filter screen 8, impurities in the irrigation fluid can be filtered out to reduce the possibility of wound infection.

[0027] Furthermore, such as Figure 1 and Figure 3 As shown, there are multiple infusion tubes 9, and one end of each infusion tube 9 is connected to an infusion drip tube 7. The other end of each infusion tube 9 is fixedly connected to the infusion needle 10. Each infusion tube 9 is also equipped with a stop clamp 11. Specifically, the stop clamp 11 is a Robert clamp. The stop clamp 11 can be used to open and close the infusion channel in the infusion tube 9. In use, each infusion tube 9 can be connected to a container containing sterile flushing solution through the infusion needle 10 to ensure sufficient flushing solution.

[0028] Furthermore, such as Figure 1 and Figure 3As shown, each infusion needle 10 is equipped with a removable protective sleeve 12. Specifically, when the infusion needle 10 is not in use, the protective sleeve 12 can be placed on the infusion needle 10. This can protect the infusion needle 10 from contamination and also prevent the infusion needle 10 from accidentally injuring medical staff. When the infusion needle 10 is in use, the protective sleeve 12 can be removed.
