Design of a multi-purpose training box for laparoscopic surgery / 第二军医大学学报

ABSTRACT

Objective To design a training box for laparoscopic skills. Methods Based on ergonomics, the size and the contour of the training box were designed with the abdominal surface data of 30 adults and extension degree of the abdominal wall under pneumoperitoneum. Port location was designed considering the optimal manipulation angel, azimuth angle and elevation angle. A flexible camera system and LED light belts were used to simulate laparoscope and light source. Training tasks were designed according to the McGill Laparoscopic Simulation study and basic laparoscopic skills. Finally, the 3D design and assembling of the training box were achieved by Autodesk Inventor, and rapid prototyping and computerized numerical control technology were used to manufacture the prototype. Results A multi-purpose training box with seven training tasks for laparoscopic surgery was successfully designed, with a size of 300 mmX 350 mmX150 mm. It was mainly composed of box, baseboard, camera system, drawer system, light belts, and seven training task modules. Conclusion The multi-purpose training box in this study is ergonomically designed and is easy to use. It can be used for training the skills of traditional laparoscopic procedures and single port surgery.
