Fig. 3From: Comparison of purse-string suture versus over-the-scope clip for gastric endoscopic full-thickness closure: traction and leak pressure testing in ex vivo porcine modelMeasurements of traction strength. a Traction machine (Autograph; Shimadzu Corporation, Kyoto, Japan). b Both sides of each closed specimen were fixed on the lower and upper arms. The upper arm automatically pulled the specimen toward the upper direction at the speed of 1Â mm/s. c Computer-generated waveform. Traction strength was measured in Newtons (N) when the dehiscence began, which correlated with the top of the first waveformBack to article page
