Microrobotics for future gastrointestinal endoscopy.
The impulse given by robotic technologies and imaging techniques to the development of a new way to conceive and perform surgery is clearly visible. Nowadays, minimally invasive surgical (MIS) procedures are often performed with the assistance of robots, such as the Da Vinci master-slave system, the AESOP robot with voice control, etc. In addition, mechatronic technologies are becoming the elective technologies for designing advanced hand-held surgical tools. The introduction of robotic technologies in endoscopy has been slower than in MIS, since the development of miniaturized robotic components for entering the small orifices of the human body is difficult. On the other hand, the large contribution that robotic technologies could bring to endoluminal techniques has been evident since the first development of instrumented catheters. In the 1990s, there was an increasing activity in the application of robotic technologies to improve endoscopic procedures in the gastrointestinal tract. The objective of robotic colonoscopy and gastroscopy was to obtain more effective diagnoses in terms of reduced pain for the patients, and to make uniform the diagnostic procedures, which too often depended on the manual abilities of the endoscopist. Currently, the availability of more reliable robotic technologies for miniaturization of size and integration of functions has allowed to conceive and develop robotic pills for the early screening of the digestive tract, with dramatic potential advantages for patients, endoscopists, and healthcare system.
