Teleoperated Probe Manipulator for Prone-Position Echocardiography Examination.

Echocardiography probe manipulation is a strenuous task. During a procedure, the operator must hold the probe, extend their arm, bend their elbow, and monitor the resulting image simultaneously, which causes strain and introduces variability to the measurement. We propose a teleoperated probe manipulation robot to reduce the burden of handling the probe and minimize the infection risk during the COVID pandemic. The proposed robot utilizes prone position scanning that could enlarge the cardiac windows for easier scanning and eliminate the risk of the robot pressing down on the patient. We derived the robot's requirements based on a real clinical scenario. Initial evaluation showed that the robot could achieve the required range of motion, force, and control. The robot's functionality was tested by a non-clinician, in which the tester could obtain heart images of a volunteer in under one minute.
