Laparoscopy is one of the first technical competencies expected of junior surgical trainees, with widespread applications across the breadth of general, urological, and plastic surgery. However, resources for the development of laparoscopic skills are limited, with proprietary laparoscopic trainers stocked by hospitals restricted by expense, minimal stock, or outdated technology. To overcome these limitations, a number of do-it-yourself designs have been described in the literature – however, these typically employ low quality, repurposed materials such as cardboard or not-for-purpose thin plastic, with imprecise hand-cut port holes and poor visibility. Increasing access to custom fabrication technology like laser cutting and 3D printing has facilitated the design of a precise, customised template that can be used for the cheap production of multiple laparoscopic trainers with ease. We describe the use of a computer aided design (CAD) program and a laser cutter to produce 4 laparoscopic box trainers using 3mm acrylic sheets. Variations of the box trainer were made to generate separate price points ranging from $30-$80: variably incorporating a port for a phone to serve as a static camera and light; a tablet as a viewing screen; and a rod mounted camera to mimic an endoscopic camera. Instruments for dexterity training exercises were designed in CAD and 3D printed for attachment at the base of the box. Laparoscopic box trainers are evidence-based to improve performance in clinical care amongst junior trainees, and the design of a cheap, mass-producible model would be an invaluable tool to supplement the training of junior trainees in this essential surgical fundamental skill.
