Development of a Master-Slave System for Active Endoscope Using a Multi-DOF Ultrasonic Motor
Endoscopes for industrial and medical fields are expected to have multi degree-of-freedom (DOF) motions. A multi-DOF ultrasonic motor we developed consists of a spherical rotor and a bar-shaped stator, and the rotor rotates around three perpendicular axes using three natural vibration modes of the stator. In this study, a multi-DOF unilateral master-slave system for active endoscope using the m...
متن کاملMiniaturized Phased-Array Ultrasonic Endoscope Initial Experience With Intracardiac Imaging in Piglets
Background. Recent advances in miniaturization of phased-array and mechanical ultrasound devices have resulted in exploration of alternative approaches to cardiac and vascular imaging in the form of transesophageal or intravascular imaging. Preliminary efforts in adapting phased-array endoscopes designed for transesophageal use to a transvascular approach have used full-sized phased-array devic...
متن کاملA Simple Stereoscopic Endoscope
A very simple method is described for producing and viewing stereoscopic endoscopic images. The addition of two simple prisms to the end of a conventional television-monitored endoscope with a simple viewing device produces a stereoscopic endoscope which appears to be suitable for surgical use.
متن کاملEndoscope-assisted myringoplasty.
INTRODUCTION To date, myringoplasty conducted under the operating microscope has been found to have its limitations. With the introduction of the endoscope into other branches of surgery, there have been attempts at its utilisation in otology. METHODS Endoscope-assisted myringoplasty was carried out in 50 patients aged 18-45 years using the temporalis fascia graft. The middle ear was examined...
متن کاملUrogenital photoacoustic endoscope.
Photoacoustic (PA) endoscopy for human urogenital imaging has the potential to diagnose many important diseases, such as endometrial and prostate cancers. We have specifically developed a 12.7 mm diameter, rigid, side-scanning PA endoscopic probe for such applications. The key features of this endoscope are the streamlined structure for smooth cavity introduction and the proximal actuation mech...
