Fig. 2 is a partially enlarged view of a supporting unit 100 of the lifting device used in the anastomosis procedure of this embodiment. Fig. 1-2 show the supporting units 100 in a first locked state, fig. 3 is a schematic view showing the overall structure of the pulling device used in the anastomosis procedure, and fig. 4 is a partially enlarged view showing the supporting units in the pulling device used in the anastomosis procedure (fig. 3-4 show the supporting units 100 in a second locked state). In use, when the support unit 100 is in the second locked state (fig. 3-4), the support unit 100 extends from the esophageal stump into the esophagus, and then the support unit 100 is switched to the first locked state by the operation portion 320, wherein the support unit 100 extends two support ends 120 towards the circumferential side of the connecting rod 200 to support the esophageal wall. When the supporting unit 100 in the lifting device is in the first locking state, the operator does not need to continuously operate the lifting device, and the lifting device in the first locking state is fixed to a proper position. Therefore, the whole process of anastomosis can be realized by one operator, and the problem of improper action caused by poor personnel fit due to two-person operation is avoided; meanwhile, because the supporting unit 100 is a hard structure, the two supporting ends 120 can well support the esophagus, so that the stable lifting action of the esophagus can be realized, and the stability and accuracy of the whole operation are ensured.
