Test device for intestinal canal suture and test method suitable for device

The invention discloses a test device for intestinal canal suture. The test device comprises two sections of to-be-sutured intestinal canals; each to-be-sutured intestinal canal comprises an intestinal canal incision surface and a suture zone close to the intestinal canal incision surface; and the two sections of to-be-sutured intestinal canals are a to-be-sutured intestinal canal A and a to-be-sutured intestinal canal B respectively. The test device further comprises a tension display device; and the tension display device comprises a pressure sensor arranged on the suture incision surface ofthe to-be-sutured intestinal canal A, a circuit box arranged outside the corresponding to-be-sutured intestinal canal and a tension display. Compared with non-measurement of existing intestinal canalsuture, the pressure sensor arranged on the suture incision surface of the to-be-sutured intestinal canal A can judge whether tension of the intestinal canal suture is proper or not directly according to numerical value displ
