The first direction is a moving direction when the cutter 121 cuts the double lumen tube 10, that is, a direction of feeding movement of the cutter 121. After the dicing operation is completed, the cutter 121 returns to the initial position in the direction opposite to the first direction. Thus, the first direction referred to in this application is defined as the direction indicated by the arrow a in fig. 3, excluding the direction opposite to a.

In some embodiments, the positioning mechanism 110 further includes a stopper 113. The limiting block 113 is disposed at one side of the positioning block 111 along the first direction. The stopper 113 is configured to be able to abut against one end of the dual-lumen tube 10 in the first direction. In this way, the limiting block 113 can limit the dual-cavity tube 10 in the first direction in the process of cutting the dual-cavity tube 10 by the cutter 121, so that the dual-cavity tube 10 is prevented from moving under the thrust action of the cutter 121, and the stable cutting operation is ensured.
