[0030] Please refer to Figure 2 and Figure 3 , fixed rings 141 are fixedly connected to the opposite surfaces of the lower clamp body 101 and the upper clamp body 102.

The anti-slip sheet 112 made of rubber can improve the stability of medical staff holding the traction device and enhance the safety of using the traction device.

[0038] Working principle: When in use, first, the two lower clamping bodies 101 and the upper clamping body 102 cooperate with the torsion spring 103 to clamp the patient's gallbladder wall and abdominal wall soft tissues respectively. At the same time, the resilience of the spring 107 can initially improve the clamping stability. The protective sheet 105 and the convex ribs 106 made of rubber can not only enhance the friction force to achieve an anti-slip effect, but also avoid damaging the patient's gallbladder wall and abdominal wall soft tissues. When pulling outside the patient's body, just pull the pull ring 162 to drive the pulling rope 109 to rotate along a plurality of rotating shafts 108, so as to adjust the distance between the two lower clamping bodies 101 and the upper clamping body 102. Then, hold the two lower clamping bodies 101 and the upper clamping body 102 and stretch them to control them to move away from each other. Therefore, the organ traction operation can be completed, and the safety and convenience of using the traction device can be improved.
