[0041] Through the above scheme: press the fixed suction disc 102 to make it tightly adsorb on the surface of the operating table, in order to cope with the possible slight inclination or unevenness of the operating table, the hydraulic buffer 103 can automatically level the second support seat 105, so as to ensure that the second support seat 105 is always in a horizontal and stable state.

[0042] As shown in Figure 1 , Figure 2 and Figure 5As shown, the posture adjustment module 3 includes a movable base 304, and the front and rear sides of the movable base 304 are fixedly connected to support slide bars 301, and the outside of each support slide bar 301 is sleeved with a sliding block 302.

The two arc-shaped fixing plates 602 are movably connected to the side facing back with an adjusting rod 603. The middle part of each adjusting rod 603 is connected to the movable pin of the connecting head 601 through a positioning pin. Both sides of the outer wall of the connecting head 601 are slidably connected with movable rings 604. Each movable ring The left and right sides of the inner wall 604 are movably connected with adjustment rods 603, and the back side of each arc-shaped fixed plate 602 is fixedly connected to a guide rod 605, and the back side of each guide rod 605 is provided with a tooth groove 606, and the inside of each tooth groove 606 is meshed with a fixed tooth block 607, and the back side of each fixed tooth block 607 is fixedly connected to a movable screw 608, and each movable screw 608 is threadedly connected to the connecting head 601.

Under the action of the thread, the fixed tooth block 607 is pushed to be inserted into the tooth groove 606 for meshing connection, thereby completing the fixation of the pipe, and the sealing performance of the connector 601 is improved by the sealing ring 6010.

[0048] Working principle:

[0049] In actual use, first, by fixing the base 1, press the fixed suction cup 102 to make it tightly adsorbed on the surface of the operating table. In order to cope with the possible slight tilt or unevenness of the operating table, the hydraulic buffer 103 can automatically level the second support seat 105 to ensure that the second support seat 105 is always in a horizontal and stable state.

[0050] Secondly, through the pipe clamping module 2, the arc-shaped clamping plates 201 on both sides are squeezed close to each other, so that the first clamping block 205 and the second clamping block 206 are clamped together, and the rotating rod 207 is used to control the limit block to complete the fixation of the first clamping block 205 and the second clamping block 206, completing the preliminary fixation of the pipe, and using the pressure adjustment knob 203, under the action of the thread, the pressure adjustment plates 202 on both sides are pushed toward each other, so that the clamping force can be finely adjusted according to factors such as the material and thickness of the pipe.

[0051] Next, through the connecting component 6, the movable ring 604 is used to push the arc-shaped fixed plates 602 on both sides to move toward each other under the action of the adjusting rod 603, so as to clamp the pipeline. The movable screw 608 is used to push the fixed tooth block 607 into the tooth groove 606 under the action of the thread to engage and connect, thereby completing the fixation of the pipeline.

[0052] Then, through the body position adjustment module 3, the telescopic connecting rods 303 on both sides are used to drive the sliding blocks 302 on both sides to move backward along the supporting sliding rod 301, so as to quickly adjust the extension length and angle of the pipeline according to factors such as the patient's body size and the depth of the surgical site. Through the universal rotation component 4, the first motor 401 is used to drive the first gear 402 to rotate, so that the second gear 403 drives the connecting sleeve 405 to rotate horizontally under the action of the first fixed shaft 404, and the second motor 407 drives the connecting block 408 to rotate vertically under the action of the second fixed shaft 406, so that the pipeline fixing system can be flexibly rotated in three-dimensional space to adapt to various changes in the patient's body position during surgery.

[0053] Finally, through the early warning module 5, the pressure sensor adopts a high-precision piezoelectric sensor to monitor the fluid pressure changes inside the pipeline in real time. The displacement sensor is based on the principle of laser interference to accurately capture the tiny displacement of the pipeline. The central processing unit has a built-in intelligent algorithm to analyze and process the received sensor data in real time. When it is judged that the data anomaly reaches the early warning threshold, an alarm is issued to medical staff through the sound and light alarm 501.
