When the hook plate is in the position, the operation is more cumbersome.

In order to solve the above problems, it is planned to adopt such a pulling device for liver exposure in laparotomy, which includes a leaf retractor, a connecting rod and a bracket. It is hinged with the lower side of one end of the connecting rod, and at least three positioning holes are vertically distributed at the end of the handle of the hook, and a sliding slot is opened on one end of the connecting rod, and the "L" shaped positioning rod is arranged in the sliding slot , and one end of the "L"-shaped positioning rod extends into the positioning hole.

In the aforementioned pulling device, the bracket includes two vertical brackets and a horizontal support rod, the two vertical brackets are respectively arranged on both sides of the operating bed, and the two ends of the horizontal support rod are respectively fixed on the two vertical brackets , the connecting rod is fixedly arranged on the transverse support rod;

In the aforementioned pulling device, the split-leaf drag hooks include three drag hooks, drag hook handles, calipers and buckles, the three drag hooks are arranged in a fan shape, and the fixed ends of the three drag hooks are all hinged to one end of the drag hook handle so that the three drag hooks Able to swing laterally, the caliper is provided with a plurality of card slots distributed along the length direction, one end of the caliper is hinged on an outer pull hook, and the other two pull hooks are respectively provided with limit blocks, and the other two pull hooks are The limit blocks are respectively clamped in the slots of the caliper, the buckles are fixedly arranged on the handle of the hook, and the buckles are also clamped in the slots of the caliper.

In the aforementioned pulling device, the buckle is also an "L" shaped structure, the middle part of the buckle is hinged on the handle of the pull hook, one end of the buckle is stuck in the slot on the caliper, and the other end of the buckle is connected to the handle of the pull hook. Springs are arranged between them.

In the aforementioned pulling device, a titanium guide wire mesh is arranged between two adjacent pull hooks.

Compared with the prior art, the utility model can not only fully pull the intestinal canal, but also expose the field of view of the operation area more ideally, and at the same time, it is convenient to use, reliable in effect, saves operation time, reduces the labor intensity of medical staff, and is suitable for popularization and application.
