The invention relates to the technical field of medical and health products, in particular to an intestinal canal traction ligator in laparoscopic surgery. The ligator comprises a ligating belt body,protruding thorns are bonded to the outer wall of one side of the ligating belt body at equal intervals, a groove is formed between every two adjacent protruding thorns on one side of the ligating belt body, one side of the outer part of the ligating belt body is sleeved with a ligating seat, a connecting belt is bonded to the outer wall of one side of the ligating seat, a traction ring is bondedto the outer wall of one end of the connecting belt, the outer wall of the traction ring is coated with a protective layer, a protruding thorn groove hole is formed in the ligating seat, the ligatingbelt body penetrates through the ligating seat to be embedded into the protruding thorn groove hole, and anti-skid lines are arranged on the two sides of the outer portion of the ligating seat at equal intervals. The ligator has the beneficial effects that: innovative surgical consumables required by the international mainstream laparoscopic surgery at present are simple and convenient to operate,the ligating belt body is provided with the anti-skid protruding thorns, loosening can be effectively prevented, the intestinal canal is sufficiently and tightly ligated, and the ligator conforms tothe tumor-free principle; the ligating belt body is a soft protruding thorn, so that the intestinal canal is not damaged; the ligating seat and the traction ring are designed to be anti-skid, tractiontension is sufficient, and surgical exposure is facilitated; and scales are arranged on the back of the ligating belt to facilitate accurate measurement of the excision range and guarantee the radical treatment effect. The ligator is made of a hot melting material, and is fused by heating so as to relieve ligating.
