Surgical robotics is one of the most rapidly developing fields within robotics. Besides general motion control issues, control engineers often find it challenging to design robotic telesurgery systems, as these have to deal with complex environmental constrains. The unique behavior of soft tissues requires special approaches in both robot control and system modeling in the case of robotic tissu...

Telemedicine promises to be one of several possible solutions to some of the medical dilemmas facing India and other developing countries. The use of communication technology in the practice of medicine may change the face of health care in India by improving access to dispersed expert medical information, diagnostic tools, and consultations. Increasing demand on practitioners’ time and the inc...

Telepresence robot extends operation in remote locations. This feature can be beneficial for several applications, such as subsea exploration, telesurgery, remote physical presence, etc. Especially, the remote physical presence application will enable individuals with mobility limitations such as disabled veteran or police officer to perform regular duties through telepresence robots known as T...

OBJECTIVE To compare robotic-assisted laparoscopic hysterectomy (RALH) with a matched control group of standard laparoscopic hysterectomy (LH). METHODS A retrospective chart review of all RALH was performed. All cases were compared with a matched control group of standard LH. Comparisons were based on Fisher's exact, Mann-Whitney, and exact chi-square tests. RESULTS Between January 2006 and...

In catheter minimally invasive neuro surgery (CMINS), catheter tip collision with the blood vessel detection during the surgery practice is important. Moreover, successful CMINS is depended on the discrimination of collision by skilled surgeon in direct operation. However, in the context of teleoperated scenario, the surgeon was physically separated. Therefore, lacking of haptic sensation is a ...

Recent progresses in robotic-aided telesurgery help the surgeons to achieve comparable performances during laparoscopic operations and classical open sky procedures. In state of the art systems ([3]), the master console provides a lightweight mechanism whose ergonomy approaches real surgical tools; slave robots are becoming sufficiently dextrous to reproduce the surgeon’s motion with great fide...

This paper proposes an endoscopic forceps manipulator with 2-DOFs bending mechanism by multi-slider linkage mechanisms and 1-DOF wire-driven grasping mechanism. Careful design of the linkage channels and restoring springs enabled unique, independent and stable bending procedure from −90 to 90 degrees on the horizontal and vertical plane to secure large working space. The manipulator consisted o...

A general-purpose augmented reality apparatus was developed. The system uses rapidly scanned lasers to display information directly onto the patient using the patient as a ‘‘projection screen’’. The device is also capable of measuring the location of projected laser spots with a 3D camera to ensure that the display is accurate, to apply corrections to the projection path and to assist in regist...

T he vision of telesurgery comprises a multitude of new communicative elements influencing the way surgeons will treat their patients in the future. The first prerequisite for effective telecommunication is to digitize surgical data. Many medical imaging modalities provide primarily digital data sets, and digital image communication is already entering clinical practice under the labels of tele...
