20150088160 | SURGICAL ROBOT FOR CHANGING POSITION OF SURGICAL EQUIPMENT - Provided is a surgical robot for changing a position of surgical equipment capable of selectively using the surgical equipment appropriate for affected areas by rotating the surgical equipment instead of changing a position of the surgical equipment by detachment, by integrating a plurality of flexible shafts having a surgical equipment attached to a leading end thereof to configure a single shaft assembly and allowing each flexible shaft to perform translation, rotation, and bending motions and rotating the shaft assembly. According to the embodiment of the present invention, the surgical robot for changing a position of surgical equipment includes: a housing | 03-26-2015 |
20150047451 | ARTICULATION FOR SURGICAL EQUIPMENT USING BALL JOINT - Provided is an articulation for surgical equipment using a ball joint fastened by the ball joint. The present invention has been made in an effort to provide an articulation for surgical equipment using a ball joint of which the shaft of pitching or yawing is not changed even though the pitching or the yawing is repeated. The articulation for surgical equipment using a ball joint is configured to include a plurality of disks; a ball joint to allow the plurality of disks to be pitched or yawed between the plurality of disks based on a longitudinal direction of the articulation for surgical equipment; and a driving wire applying a driving force to pitch, yaw, or roll the plurality of disks. According to the articulation for a surgical equipment using a ball joint according to the embodiment of the present invention, the rotating shaft of the articulation is not changed despite the repeated movement of the articulation, and since the durability of the articulation is increased, the safety of the surgical equipment can be improved when the articulation is applied to the surgical equipment. | 02-19-2015 |
20140368831 | INTERFEROMETER USING ASYMMETRIC POLARIZATION AND OPTICAL DEVICE USING THE INTERFEROMETER - The present invention relates to an interferometer and an optical device using same. Unclear interference patterns and restrictions between light source and the interferometer for conventional devices require precise control devices. The present invention enables to control a wave plate of an interferometer to make the amplitude of object beam split by a polarization beam splitter asymmetric against that of reference beam, resulting the brightness of interference patterns adjustable, while using tunable laser as light source of an optical device and adopting frequency scanning methods to prevent restrictions between light source and interferometer. The interferometer and an optical device according to the present invention comprise: a wave plate controlling polarization direction of linearly polarized light incident to a polarization beam splitter; the polarization beam splitter; a wave plate converting polarization beam for the object beam and the reference beam to be interfered in an image pick-up device; and a polarizer. | 12-18-2014 |
