... accuracy. Indeed, marked residual motion of the area of interest can be observed. In this paper, we address the problem with the design of an active stabilizer, i.e., an active mechanism controlled to cancel any residual motion during the surgery. The design methodology is based on dynamic modeling...

...Matteo Zoppi; Wiktor Sieklicki; Rezia Molfino This paper addresses the design of a microwrist for needle laparoscopic surgery (needlescopy) using microelectromechanical system technology and an original three degree of freedom, 3D architecture. Advancement in needlescopy drives the development...

...Mark E. Rentschler; Shane M. Farritor; Karl D. Iagnemma A new approach to laparoscopic surgery involves placing a robot completely within the patient. These in vivo robots are then able to provide visual feedback and task assistance that would otherwise require additional incisions. Wheeled in vivo...

...Paul Breedveld; Shigeo Hirose Visual feedback during laparoscopic surgery is provided by an endoscope with a camera that is inserted through a small incision in the abdominal wall. The incision restricts the endoscope movements to 4 degrees of freedom (DOF), making it impossible to observe organs...

... Editor: C. W. Wampler II. 01 October 1999 06 08 2002 Minimally invasive surgery (MIS) is the technique of operating on the internal organs of the body without damaging a much greater amount of surrounding healthy tissue. The techniques involve insertion of instruments and viewing...

Simpson, Assistant Professor; Alan Snyder, Associate Professor The design of a variable thickness piezoelectric bimorph actuator for application to minimally invasive surgery is proposed. The actuator...
