Miniature in vivo cameras for use in single-incision robotic surgery - biomed 2011.

Single-incision surgery provides numerous benefits over traditional open and laparoscopic surgery techniques including reduced pain, shortened recovery times, and minimal tissue scarring. The use of miniature in vivo robots inserted through a single incision offers additional advantages over conventional laparoscopy in improved maneuverability and dexterity. One consequence of performing surgical procedures through a small single incision is the loss of direct visualization through a large open incision or visualization via laparoscopic cameras inserted through additional ports. For this reason, a miniature in vivo actuated camera was designed to pass through a single incision and attach to a miniature in vivo robot, providing live video feedback at the control of the surgeon. The device was tested in a lab setting and porcine model surgery and demonstrated successful movement, control, and high-quality visualization, indicating the device’s functionality and feasibility for use in single-incision robotic surgery.
