[0034] In this embodiment, the traction device for the triple-lumen and double-balloon tube achieves an efficient and stable traction effect through its carefully designed structural components. First, the fixing mechanism 1 is connected to the bed tail through the first clamping and adjusting component 11 and is connected to the supporting mechanism 2 through the rotating seat 12. The second clamping and adjusting component 13 on the rotating seat 12 can adjust the clamping degree between the rotating seat 12 and the supporting mechanism 2. The linkage of these components ensures the firm connection between the device and the bed tail and the adjustability of the clamping degree, providing guarantee for the stability and safety of the traction device. The supporting mechanism 2 includes a pulley 3. Through the design of the supporting mechanism 2, the traction rope 4 can be smoothly transmitted, and the other end of the traction rope 4 is connected with a counterweight 5, which can ensure the precise traction of the triple-lumen and double-balloon tube. Overall, these structural components cooperate with each other to achieve reliable and accurate traction of the triple-lumen and double-balloon tube, providing a convenient and efficient tool for medical operations.

[0036] In summary, in the traction device of this three-lumen and two-balloon tube, since a contrast machine needs to be installed at the head of the DSA contrast examination bed, reliable connection is achieved through the design of the fixing mechanism on both sides of the bed tail. This enables medical staff to no longer need to hold the traction device for operation, thereby providing continuous and stable traction force, avoiding the cumbersome and inconvenient manual operation by medical staff. The continuous and stable traction force ensures that the three-lumen and two-balloon tube maintains a constant pressure and position during use, thus improving the hemostasis effect and treatment accuracy, and further ensuring the smooth progress of the operation and the safety of the patient. Secondly, the design of the first clamping and adjusting component 11 and the second clamping and adjusting component 13 of the fixing mechanism 1 allows the clamping degree of the traction device to be adjustable and is detachably connected to the bed tail. This design allows medical staff to adjust the clamping degree of the fixing device according to specific needs to meet the usage requirements in different situations.

This design enables medical staff to adjust the fixing degree of the device according to actual needs, ensures the firm connection between the device and the bed tail, and improves the stability and safety of the operation.

[0039] In summary, the design of the fixed seat 111, the threaded groove and the adjusting screw 112 enables medical staff to precisely adjust the clamping degree between the fixing mechanism 1 and the bed tail to ensure the stable connection and traction effect of the device.

[0040] Furthermore, referring to Figure 4 , a connecting member 1111 is provided on the fixed seat 111, and the connecting member 1111 is rotatably fitted with the rotating seat 12 so that the rotating seat 12 can rotate relative to the fixed seat 111.

The connecting member 1111 rotates on the fixed seat 111, allowing the rotating seat 12 to rotate relative to the fixed seat 111. This design enables medical staff to adjust the angle of the rotating seat 12, thereby flexibly controlling the direction and position of the traction device, ensuring the flexibility of operation and the accuracy of traction.

[0042] In summary, the design of the connecting member 1111 and the rotating seat 12 enables the rotating seat 12 to rotate relative to the fixed seat 111, thereby achieving the angle adjustment of the support mechanism 2, and further adjusting the position and angle of the traction device, ensuring the accuracy and comfort of traction.

The first meshing portion 1113 with a wavy end on it meshes with the second meshing portion 121 on the rotating seat 12. When these two meshing portions cooperate, the angle between the fixed seat 111 and the rotating seat 12 will be locked and no further angle adjustment can be made, thus achieving a stable connection. This design ensures the stability of the traction device, provides a reliable operating environment for medical staff, and guarantees the smooth progress of the surgical operation and the safety of the patient.

[0045] In summary, when the first meshing portion 1113 and the second meshing portion 121 are in meshing cooperation, the angle between the fixed seat 111 and the rotating seat 12 will be locked and no further angle adjustment can be made, achieving a stable connection and ensuring the stability of the traction device.

The support mechanism 2 is connected to the rotating seat 12 through this through hole, enabling the support mechanism 2 to move flexibly on the rotating seat 12, thereby adjusting the position and angle of the traction device. This design scheme provides convenience for the installation of the traction device, ensuring the flexibility of operation and the accuracy of traction.

The adjusting end of the second clamping and adjusting component 13 passes through the second through hole 123 and is abutted and connected to the support mechanism 2. This design scheme enables the second clamping and adjusting component 13 to adjust the position of the support mechanism 2 through the second through hole 123, thereby adjusting the angle and position of the traction device. Through this linkage, medical staff can easily adjust the angle and position of the traction device, ensuring the accuracy and comfort of traction.

The adjusting rod 131 is in threaded engagement with the second through hole 123 and rotates through the handle 132. When the handle 132 rotates, the adjusting rod 131 also rotates accordingly, so that the adjusting rod 131 moves along the axial direction of the second through hole 123 and abuts against the support mechanism 2. This design enables medical staff to easily adjust the position of the support mechanism 2 through the handle 132, thereby adjusting the angle and position of the traction device, ensuring the accuracy and comfort of traction.
