| Abstract: |
| Objective To make the horizontal and vertical mechanical evaluation for different access devices (Port) in transumbilical laparoscopic surgery, and to compare the maneuverabilities of these devices during the process. MethodsA laparoscopic training box was combined with Multi-ports, TriPort and SILS Port to construct the evaluation platforms. A universal testing machine was used for evaluating the mechanics of the three devices on horizontal and vertical direction by traction experiments. ResultsIn the horizontal traction experiment, the forces were significantly different on the instruments with different access devices (Multi-ports
