[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1 As shown, this utility model provides an adjustable hepatobiliary drainage tube fixation device, including: a fixation base 1, an adapter 2, and a fastening base 4 disposed at the end of the adapter 2. The fixation base 1 is generally configured as a circular ring structure, and bandages 11 are symmetrically arranged on both sides of the fixation base 1. When in use, the fixation base 1 is tied to the human body by the bandages 11. The drainage tube passes through the adapter 2 and is vertically inserted into the human body from the bottom of the fixation base 1 to perform the drainage function.

[0022] One end of the adapter 2 is rotatably connected to the fixed base 1, and the other end of the adapter 2 is provided with a fastening base 4. Several sets of fastening bases 4 are provided, and the several sets of fastening bases 4 cooperate with each other to achieve the effect of clamping the inserted drainage tube.

[0023] Please see Figure 2 , Figure 3 , Figure 5 , Figure 6 The inner wall of one end of the adapter 2 is provided with an inclined guide surface 24, and the outer wall of the fastening seat 4 is provided with an inclined guide surface 43. The inclined angles of the guide surface 24 and the guide surface 43 are the same, and the two fit together. When the fastening seat 4 moves along the guide surface 24, the position of its inner wall will change in the radial direction, and the position between several sets of fastening seats 4 will change, thereby clamping or loosening the drainage tube that passes through.

[0024] A limiting block 44 is provided on the second guide surface 43. The limiting block 44 is locked in the limiting groove 25 of the first guide surface 24, and the limiting block 44 passes through the guide hole 45 and is inserted into the guide rod 26 in the groove. This setting can limit the movement direction of the fastening seat 4, prevent it from deviating in direction, and also prevent the fastening seat 4 from falling off the adapter 2.

[0025] A compression spring 27 is fitted around the outside of the guide rod 26. The compression spring 27 is located on the side of the limiting block 44 near the end of the adapter 2. When the fastening seat 4 is pulled outward, the limiting block 44 moves and compresses the compression spring 27. The elastic force of the compression spring 27 always presses the limiting block 44 into the adapter 2, which is beneficial to the closed state of the fastening seat 4 and makes it convenient for the fastening seat 4 to press the drainage tube.

[0026] Several sets of buffer pads 42 are evenly arranged on the inner side of the fastening seat 4. The buffer pads 42 are in direct contact with the drainage tube and play a buffering and protective role between the drainage tube and the fastening seat 4. The fastening seat 4 is bent and equipped with a clamping plate 41. The clamping plate 41 is designed to provide a force application point for the user when operating the fastening seat 4, making the operation easier.

[0027] Please see Figure 2 , Figure 4 The fixed base 1 is provided with a through hole, which is aligned with the adapter 2. A connecting pipe 22 is provided at the end of the adapter 2 that is connected to the fixed base 1. The connecting pipe 22 ensures that the bottom end of the adapter 2 is always connected with the through hole of the fixed base 1 during the up and down movement.

[0028] The adapter 2 is externally equipped with a positioning frame 21, which moves with the adapter 2 as it moves up and down. An elastic plate 5 is located at the lower part of the positioning frame 21. The elastic plate 5 pushes the positioning frame 21 upwards, causing the positioning hole 23 on the upper part of the positioning frame 21 to engage with the positioning pin 31 in the adapter seat 3, thereby limiting the angle of the adapter 2 and preventing it from rotating. When it is necessary to change the orientation of the drainage tube, simply press the adapter 2 down, pressing the elastic plate 5 down, separating the positioning hole 23 from the positioning pin 31, allowing the adapter 2 to rotate. After rotation, releasing the adapter 2, the elastic plate 5 re-engages the positioning hole 23 with the positioning pin 31 for positioning.

[0029] The elastic structure consists of a spring rod 51 and a sleeve 52. The spring rod 51 is connected to the sleeve 52 and is connected to the return spring. When the elastic plate 5 is pressed down, the return spring is compressed through the spring rod 51.
