Automatic guidance of an assistant robot in laparoscopic surgery

The Surgical Assistant Workstation

The Surgical Assistant Workstation (SAW) is a software development framework that can be used to develop new applications in robot-assisted surgery with augmented visualization. Robot-assisted laparoscopic surgery and micro-surgery—as presented by the da Vinci telerobotic system and the Johns Hopkins Steady Hand, respectively—can be improved by providing fully-integrated image guidance and info...

Application of visual tracking for robot-assisted laparoscopic surgery

With the increasing popularity of laparoscopic surgery, the demand for better modes of laparoscopic surgery also increases. The current laparoscopic surgery mode requires an assistant to hold and manipulate the endoscope through commands from the surgeon. However, during lengthy surgery procedures, accurate and on time adjustment of the camera cannot be guaranteed due to the fatigue and hand tr...

How Does the Camera Assistant Decide the Zooming Ratio of Laparoscopic Images? Analysis and Implementation

An important factor for defining a good image during laparoscopic surgery is the zooming ratio, which corresponds to the depth of insertion of the laparoscope along its longitudinal axis. However, it is not clear how surgeons (camera assistants) decide the zooming ratio of laparoscopic images during surgery. Conventional automatic camera positioning systems define the zooming ratio "uniformly" ...

Tumor Detection and Morphology Assessment in the Liver Tissue Using an Automatic Tactile Robot

In this paper an automatic examination robot was developed to improve the process of cancer detection, tumor localization and geometrical shape diagnosis. A uniformly distributed compressive load was applied to the top tissue surface and the resultant mechanical stress was measured that was employed for the tumor diagnosis task. The experimental examinations were performed on the soft tissue of...
