“…Alternatively, it shows a pair of two-dimensional views of separate abdominal fields. These images are provided while freeing a port lumen for insertion of other instruments [20,21]. University of Nebraska independently developed a mobile camera robotic system called Mobile Adjustable-focus Robotic Camera (MARC) that deploys through an access port and maneuvers throughout the abdomen.…”

“…To overcome these drawbacks, other types of endoscopes/vision devices have been explored in the literature (some are now commercialized) such as stereoendoscopes [4], or a digital camera directly placed inside the abdominal cavity [6]. Other solutions, based on software approaches have been proposed as for instance augmented reality, where a virtual model of the operative site is projected on the real image [1], [3], [7], or virtual reality where a 3-D virtual environment of the surgical scene is displayed so that the surgeon can plan the surgery or be guided in real time [11], [10].…”

7th International Workshop, AE-CAI 2012, Held in Conjunction with MICCAI 2012, Nice, France, October 5, 2013, Revised Selected PapersMinimally invasive surgery became popular as it benefits the patient, reducing pain and allowing better recovery. However, during endoscopy, surgeons face significant technical challenges such as indirect 2-D visualization, restricted field-of-view, lack of brightness, insufficient depth-of-field, distortions, etc. In this paper, we propose a new vision system for laparoscopy. This system consists of two pairs of cameras in stereoscopic conditions directly inserted into the patient through a single standard 10 millimeters diameter trocar and be deployed and fixed into the patient's abdominal cavity. It answers several problems raised by standard endoscopic systems as well as a 3-D virtual environment

“…In [17] and [18], camera robots are developed with two active internal degrees of freedom (DOFs) and magnetic anchoring. A stereoscopic robotic camera (2 DOFs: pan and tilt) is described in [19] and [20]. However, this device does not include a lighting system nor an anchoring system, and it is sutured on the abdominal wall during experimental validation.…”

In this paper, the authors present an innovative vision platform for laparoendoscopic single-site (LESS) surgery based on a wired and magnetically activated 5-degrees-of-freedom robot with stereovision. The stereoscopic vision module, developed using two off-the-shelf cameras and a light emitting diodes lighting system, is mounted on the robot tip. An autostereoscopic screen is adopted to display the surgical scenario as an alternative to 3-D helmets or polarizing glasses. A rough position of the stereocamera can be determined along the abdominal wall by dragging the robot with a set of external permanent magnets (EPMs). Once the camera is set in the desired position, the EPMs provide fixation, while the internal mechanism allows fine tilt adjustment. Considering the deformable round shape of the insufflated abdomen wall and in order to replicate the precise roll motion usually provided by the endoscopist's hands, this prototype embeds an actuated mechanism that adjusts the stereocamera horizon and thus prevents any visual discomfort. Finally, the platform was preliminarily tested in vivo in a LESS scenario, demonstrating its advantages for eliminating potential conflicts with the operative tools and enabling the introduction of an additional instrument through the same access port used for stereoscopic vision.

Initial trial of a stereoscopic, insertable, remotely controlled camera for minimal access surgery

Abstract: This preliminary proof-of-concept study suggests that a stereoscopic, insertable, remotely controlled camera may provide better visualization during minimal access surgery by overcoming many of the limitations of video-laparoscopy.
