Position control of a surgical robot by a navigation system

Determination of optimal non‐invasive patient fixation methods for use in robotic hip replacement surgery—an in vitro study

“…0.5 mm (4). The problem of coupling a navigator with a robotic device in orthopaedic surgery using active or semi-active robotic devices has been addressed mainly on a theoretical basis (8,9). There is agreement that a fixation of the tracking markers in orthopaedic procedures will have to be at the level of the bony structures (6).…”

Detection of the spatial accuracy of a magnetic resonance and surgical computed tomography scanner in the region of surgical interest

“…These advantages have led to safer operations and to shorter recovery times. [1][2][3][4] Usually, IGS uses preoperative image data of the patient 3 meaning that the surgeon has to take into account the possible image distortions and artifacts 5 and also changes that occur in the patient's anatomy during operations. Other sources that affect the quality of IGS include technical accuracy, registration accuracy, and application accuracy.…”

Design and analysis of a head-mounted parallel kinematic device for skull surgery

“…Autonomous or cooperative systems compensate for the surgeon's restricted view of the site of the intervention by integrating additional systems for patient localization or registration. Most autonomous systems take advantage of frameless navigation provided by stereo optical cameras [2,3,18]. To prevent a loss of registration during the intervention, the patient has to be either tracked or immobilized relatively to the robot.…”
