In addition, in a complicated laparoscopic surgery, such as laparoscopic pancreatoduodenectomy, the organ is pulled by two assistant operation holes in a limited manner, so that the surgical field is difficult to expose, the organ is generally required to be sutured by a suture or a sling is fixed on the abdominal wall to assist in pulling the organ, and the defects of the complicated laparoscopic surgery, such as trauma, relatively complicated operation, incapability of moving and the like are caused.

Surgical field exposure is a difficulty during laparoscopic surgery, and tissue structures within the surgical field are often pulled in order to expose the surgical field. The common traction device is a magnetic anchoring traction device, and the tissues needing to be suspended are hooked by the drag hook through the magnetic attraction force of the inner magnet and the outer magnet, so that the operation visual field is exposed.

However, the technology still has the following defects: the tissue is hooked by a single drag hook, the edge part of the tissue is still in a sloughing state, and the difficulty of surgical field exposure cannot be completely solved. The traction force applied by the draw hook to the suspended tissue is fixed and inelastic, namely the suspended tissue is still in the position after being separated, and still needs to be pulled and exposed by a surgical assistant, so that surgical instruments are added, and the practicability of the traction device is low.
