[0021] A percutaneous transhepatic biliary drainage tube of the utility model will be described in more detail below in conjunction with the accompanying drawings, wherein preferred embodiments of the utility model are shown, and it should be understood that those skilled in the art can modify the utility model described herein while still achieving the beneficial effects of the utility model. Therefore, the following description should be understood as being widely known to those skilled in the art, and not as a limitation to the utility model.
[0022] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.
[0023] like Figure 1 and Figure 2 As shown, the embodiment of the utility model provides a convenient and practical percutaneous transhepatic biliary drainage tube, comprising a tube body and a needle connected to each other. For the sake of simplicity of the diagram, the needle is not drawn in the figure.
[0024] Specifically, the tube body includes an annular tube wall 1 and a drainage port 2 located at the center of the annular tube wall 1; a water inlet 11, a flushing cavity 12, a flushing port 13 and a fixing device are provided in the annular tube wall 1; one end of the water inlet 11 is connected to the flushing cavity 12, and the other end is used to be connected to a water supply device; the flushing port 13 is connected to the flushing cavity 12 and is close to the needle; the fixing device is located between the flushing port 13 and the water inlet 11, and is used to fix the tube body; the drainage port 2 is connected to the needle.
[0025] Preferably, the water inlet 11 can be connected to the water supply device via a joint.
[0026] By setting up the fixing device, the overall stability is improved, thereby improving the stability of the drainage process and reducing the risk of bile retention and infection.
[0027] In this embodiment, the fixing device includes a slide groove 15, a push plate 14, a device groove 18, a first rotating member 16 and a second rotating member 17 arranged in the annular tube wall 1. Specifically, the push plate 14 is slidably arranged in the slide groove 15, and extends into the device groove 18 to be rotatably connected with the first rotating member 16; the first rotating member 16 and the second rotating member 17 are both located in the device groove 18; one end of the second rotating member 17 is rotatably connected with one end of the first rotating member 16 away from the push plate 14, and the other end is rotatably mounted on the device groove 18.
[0028] The slide groove 15 is connected to the device groove 18 .
[0029] Furthermore, the fixing device further comprises a moving block 19 . Specifically, the moving block 19 is slidably disposed in the device slot 18 , one end of which is fixedly connected to the push plate 14 , and the other end of which is rotatably connected to the first rotating member 16 .
[0030] Preferably, the first rotating member 16 and the second rotating member 17 are both made of silicone. Further, the first rotating member 16 and the second rotating member 17 are both made of medical hard silicone, thereby improving durability and comfort. In addition, the adsorption property of silicone material is utilized to facilitate the first rotating member 16 and the second rotating member 17 to fit the human body, thereby improving the stability of the device.
[0031] In this embodiment, the length of the first rotating member 16 is smaller than the length of the second rotating member 17. The actual sizes of the first rotating member 16 and the second rotating member 17 can be set according to actual conditions.
[0032] In one embodiment, the slide groove 15 and the push plate 14 are both L-shaped structures or T-shaped structures.
[0033] Furthermore, the push plate 14 extends out of the slide slot 15 , making it easier for medical personnel to push the push plate 14 .
[0034] Preferably, the number of the fixing devices is multiple. For example, there may be two fixing devices, and the two fixing devices are symmetrically arranged to increase the fixing area and improve the fixing effect.
[0035] In a specific example, the flushing cavity 12 is an annular structure. The number of the flushing ports 13 is multiple. The multiple flushing ports 13 are arranged on the pipe wall in an annular arrangement and communicated with the flushing cavity 12 of the annular structure to increase the water output and improve the flushing effect.
[0036] Preferably, a one-way valve 130 is provided in the flushing port 13. Through the provision of the one-way valve 130, water can only flow out of the flushing port 13, thereby preventing bile from entering the flushing port 13 and blocking the flushing port 13.
[0037] In this embodiment, the device is inserted through the human skin tissue layer through the needle until the rest of the device is located in the human body except for the portion where the push plate 14 extends to the slide groove 15. Figure 1As shown, by manually pushing the push plate 14 (until the push plate 14 and the slide groove 15 are close to the inner wall of the device groove 18 and cannot be pushed), the push plate 14 slides in the direction of the needle tip, and pushes the moving block 19 to slide in the direction of the needle tip. When the moving block 19 moves, the end of the first rotating member 16 connected to the second rotating member 17 rotates outward from the device groove 18 with the moving block 19 as the center of the circle. When one end of the first rotating member 16 rotates, the end of the second rotating member 17 connected to the first rotating member 16 is driven to rotate with the other end of the second rotating member 17 as the center of the circle, thereby realizing the expansion of the first rotating member 16 and the second rotating member 17, so that the side of the first rotating member 16 away from the device groove 18 is attached to the human skin tissue layer through the adsorption characteristics of the silicone material, thereby realizing the fixation of the device. Then the drainage operation can be performed.
[0038] When the bile duct needs to be flushed, the water inlet 11 only needs to be connected to the water supply device through a joint, so that water can enter the bile duct through the flushing cavity 12 and the flushing port 13.
[0039] like Figure 2 As shown, when the device needs to be removed from the body, it is only necessary to pull the push plate 14 in the direction away from the needle to drive the moving block 19 to move until the moving block 19 is in close contact with the inner wall of the device groove 18 (referring to the inner wall close to the slide groove 15). The movement of the moving block 19 drives the first rotating member 16 to rotate into the device groove 18 with the moving block 19 as the center of the circle. The rotation of the first rotating member 16 drives the second rotating member 17 to rotate into the device groove 18 with the end of the second rotating member 17 away from the first rotating member 16 as the center of the circle, thereby completing the contraction of the first rotating member 16 and the second rotating member 17. Finally, the tube body can be pulled out.
[0040] In summary, the percutaneous transhepatic biliary drainage tube proposed in the utility model has the following advantages:
[0041] Through the arrangement of interconnected tube body and needle; the tube body includes an annular tube wall and a drainage port located in the center of the annular tube wall; the annular tube wall is provided with a water inlet, a flushing cavity, a flushing port and a fixing device; one end of the water inlet is connected to the flushing cavity, and the other end is used to be connected to the water supply device; the flushing port is connected to the flushing cavity and is close to the needle; the fixing device is located between the flushing port and the water inlet and is used to fix the tube body; the drainage port is connected to the needle.
