[0002] Hepatobiliary surgery mainly studies diseases such as hepatocellular carcinoma, hepatobiliary stones, post-hepatitis cirrhosis and acute liver failure caused by severe hepatitis. Hepatobiliary surgery is characterized by precise, minimally invasive and systematic surgical treatment, covering the sub-specialty fields of liver surgery, biliary surgery, pancreatic surgery, portal hypertension surgery and transplant surgery. After hepatobiliary surgery, patients often have a central venous catheter left on the skin surface to treat the patient through this catheter. In the process of patient care, catheter care is also very important. The catheter needs to be fixed with a catheter fixing device to prevent the movement of the catheter from causing skin wound infection. The existing catheter fixing device generally needs to move the catheter left and right to fix the two side wings of the catheter on the surface of the device before the fixing device can be attached to the skin surface. Since the wound is prone to infection and damage, frequent movement of the catheter may cause a certain degree of damage to the patient's wound if not careful. Utility Model Content

[0022] The bottom of the top cover 3 is provided with a placement groove 4 and a placement seat, which is convenient for the two wings of the catheter to be inserted into the placement groove 4, so that the internal structure can clamp and fix the two wings of the catheter. The frame 5 is designed to be convenient for clamping and connecting the push rod 10 by opening a through hole on its outer surface. The inner wall of the through hole is tightly clamped with the outer surface of the push rod 10 to prevent the push rod 10 from loosening due to excessive gap and failing to clamp the side wings of the catheter. The handle 6 is designed on the outer surface of the push rod 10 to facilitate the effect of pushing the push rod 10 by applying pressure to the handle 6. The base 7 is designed. Because the two wings of the catheter connection end are symmetrically arranged, the base 7 and the placement seat are symmetrically arranged to prevent the other side wing from being unable to be fixed. A notch is opened at the center of the base 7 to facilitate the fixing column 8 to be clamped in the notch and not easy to move. The fixing column 8 movably connected to the notch 8 is used to pass through the circular hole on the side wing and fix the side wing to the upper end of the base 7. Therefore, the outer surface of the fixing column 8 is designed to be engaged with the inner wall of the circular hole. The top of the fixing column 8 is fixedly connected to the horizontal plate 9, and the two ends of the horizontal plate 9 are not fixedly connected to the connecting column 13, which is convenient for opening and closing the horizontal plate 9, so that the side wing can be clamped at the bottom of the horizontal plate 9 through the fixing column 8 without moving the side wing. By designing a push plate 11 fixedly connected to the top of the push rod 10, and the outer surface of the push plate 11 is tightly fitted with the surface of each structure it contacts, so that the push plate 11 will not move actively, and at the same time, the sponge pad 12 is relatively soft and can be attached to the surface of the side wing by the pressure of the push plate 11.

[0025] In this embodiment, by designing the card slot 14, the cross plate 9 can be fixed to the top of the connecting column 13 by the card block 15 fixedly connected at one end thereof. By fixing the protruding blocks 16 on both sides of one end of the cross plate 9, the cross plate 9 can be pulled up by buckling the protruding blocks 16 on both sides to make the card block 15 disengage from the card slot 14, and at the same time drive the fixed column 8 to move. By designing the movable sheet 17 on the outer surface of the connecting column 13 and the cross plate 9, the cross plate 9 can be rotated by the movable sheet 17 without being disengaged from the connecting column 13. The movable sheet 17 can be a thin plastic sheet or a thinner leather material, both of which can achieve the effect of one-time connection and rotation.
[0026] Working principle:
[0027] like Figure 1-Figure 4 As shown, when using the fixing device to fix the central venous catheter, pull up the horizontal plate 9 in advance by buckling the protruding block 16, so that the block 15 is disengaged from the slot 14, the fixing column 8 is disengaged from the base 7, and is flipped and placed on one side. After the patch 1 is straightened through the thin aluminum sheet 18, it passes through the bottom of the catheter, and the side wings are aligned with the placement slot 4 until the side wings completely enter the placement slot 4. Then the patch 1 can be attached to the skin surface, and then the index finger and thumb slowly press the two handles 6 to push the push rod 10 and the push plate 11 to move inward, and the sponge pad 12 can be attached to the surface of the side wing to complete the fixation of one side. The other side wing has been placed on the upper end of the base 7.
