Development of a laparoscopic training model using a smartphone.

Abstract

to develop a model of training in video-surgery, of low cost and that uses a smartphone as an image-generating source. We developed a 38cm high, 40cm wide, 40cm long hexagonal-shaped training box, with a front opening of 12x8 cm for coupling the smartphone. The internal illumination is made with LED lamps and for the support of the smartphone, we used a selfie stick, fixed in the upper part of the box, that allows control of height, distance, angulation, and the coupling of devices with different formats. We selected 20 undergraduate students without previous training in video-surgery, who performed four exercises in the box, with assessment of the time and amount of errors in the execution of the tasks. Each student completed the training for three consecutive weeks. We collected the data in spreadsheets for later analysis. Nineteen students completed the training program, with significant improvement in the times and in the number of errors. the developed model was feasible and promoted the acquisition of skills in this group of students. In addition, it presents low cost, is portable and uses common equipment, such as smartphones.
