Use your phone to build a simple laparoscopic trainer.

Simulation is becoming increasingly integral to surgical training with progressive restrictions on working hours. This paper describes a unique, cable free, laparoscopic trainer that can be constructed using items readily available to the average surgical trainee. The trainer described is not a substitute for surgical practice but, nonetheless, a useful tool in developing skills such as hand-eye co-ordination, triangulation and depth queuing.

Simulation has become an integral part of surgical training as it provides a safe method of acquiring core, transferable skills at a time where restrictions in working hours may limit exposure. Laparoscopic trainers are an example of a successful adjunct in developing skills such as hand-eye co-ordination, triangulation and depth queuing. Commercial laparoscopic trainers are expensive, making them unattainable to most trainees. Inexpensive, home-made laparoscopic trainers have previously been described[12] but these require the purchase of a webcam and the use of cables. Here, we describe a unique, cable free, laparoscopic trainer that can be constructed using items readily available to the average surgical trainee at no additional cost.

Four items are required: A smart phone, a tablet computer, a torch and a box. We used an iPhone 5, an iPad mini, a Petzl headlamp and a cardboard box. Step 1: Modify the box to create a bevelled surface to hold the smart phone [Figure 1]. Cut a hole for the smart phone camera. Place the torch inside the box. Step 2: Download/install an application to the phone and tablet allowing the phone camera to act as a remote camera (we used WiFi Camera). Step 3: Obtain laparoscopic tools (out-of-date equipment are often available) and the trainer is ready [Figure 2]. Many variations of the above can be constructed depending on type of smart phone, tablet computer and software available to the surgical trainee. Additionally, a conventional laptop or desktop can be used provided WiFi capability.

The trainer described is simple, can be constructed in 15 minutes, with equipment often readily available. This is not a substitute for surgical practice but, nonetheless, a useful tool in developing laparoscopic skills.
