Video system design of a miniature cable-free robot for LESS

Laparo-endoscopic single-site surgery (LESS) is a promising and important alternative improvement for the limits of classical surgical robot systems, and has become a popular issue in minimally invasive surgery (MIS). This paper describes a video system design of a miniature, low power consumption and cable-free robot which can provide real-time video of operation target area in MIS. The magnetic anchor robot can be inserted into abdominal cavity through just only an incision. The system includes: (1) a miniature wireless camera which provides realtime video, (2) a wireless control illumination subsystem, (3) a wireless control subsystem, (4) a human-machine interface to control the platform. Low-power dissipation performance of the system is verified by experiment, and the feasibility of the system is successfully verified by an ex-vivo experiment on porcine kidney. This imaging robot can be used in MIS for view feedback and integrating with surgical tools such as manipulator, it will become an in vivo anchored surgical robot for LESS.
