Preliminary design of an actuated imaging probe for generation of additional visual cues in a robotic surgery.
Surg Endosc
June 2016
Department of Mechanical and Industrial Engineering, Qatar University, Doha, Qatar.
Background: The aim of this study was to enhance the visual feedback of surgeons, during robotic surgeries, by designing and developing an actuated 2D imaging probe, which is used in conjunction with the traditional stereoscopic camera of the da Vinci surgical system. The probe provides the surgeon with additional visual cues, overcoming visualization constraints encountered during certain scenarios of robot-assisted minimally invasive surgery.
Methods: The actuated imaging probe is implemented as a master-slave tele-manipulated system, and it is designed to be compatible with the da Vinci surgical system.
Structural limitations of currently available microcatheters and coils for endovascular coiling of very small aneurysms.
Neuroradiology
May 2008
Department of Neurosurgery, School of Medicine, Ajou University, Yongtong-Ku, Suwon 442-721, Republic of Korea.
Introduction: Coil embolization for very small aneurysms (<3 mm in maximum diameter) has been considered a technically challenging method due to increased risk of potential aneurysm perforation during the procedure. We present our observations about the structural limitations of eight types of microcatheters and three types of detachable coils, and technical pitfalls in the coiling of very small aneurysms.
Methods: The structures of each type of microcatheter and coil were carefully evaluated under a stereoscopic microscope.
