| 20100094082 | MEDICAL EXAMINING DEVICE WITH AN ANGULARLY OFFSET FIBER OPTIC CHANNEL - There is provided a medical examining device including an hollow sample tube defining a tube first end and an opposing tube second end. The sample tube includes a tube wall extending between the tube first and second ends. The tube wall includes tube inner and outer surfaces extending between the tube first and second ends. The tube inner surface defines a central sampling channel configured to longitudinally receive a sampling tool. A longitudinal channel partially extends through the tube wall between the tube first end towards the tube second end along an optical axis. The optical axis is angularly offset and extends toward the sampling channel axis adjacent the tube second end. A translucent lens is positioned in optical communication with the longitudinal channel adjacent the tube second end. A fiber optic viewing device is disposed within the longitudinal channel and is in optical communication with the translucent lens. | 04-15-2010 |
| 20100280314 | UROLOGICAL RESECTOSCOPE COMPRISING HOLES - A resectoscope comprising a shaft that has an external tube and an internal tube. A lens system which has an angular field of view and can be rotated relative to the external tube along with the internal tube is disposed inside the internal tube. The distal end region of the internal tube is designed to slide in a sealed manner along the external tube. The external tube has holes in the distal end region proximal to the end region of the internal tube. The interior of the internal tube is connected as a supply duct while the intermediate space between the tubes is connected as a discharge duct. The disclosed resectoscope is characterized in that the holes are distributed along the circumference, while the internal tube is fitted with a covering device which covers the holes in a circumferential zone. | 11-04-2010 |
| 20100312053 | RESECTOSCOPIC DEVICE AND METHOD - A surgical instrument has a channel dimensioned to receive a viewing instrument and enable the viewing instrument to be moved to or from a position near an optically transparent portion of a blunt, enclosed distal end of a shaft to provide unobstructed viewing through the distal end, and a position to the proximal side of an enclosed working area to provide viewing of the enclosed working area. A surgical instrument also or alternatively has a fluid routing switch within a shaft which can selectively connect a fluid infusion channel to at least one fluid export pore or a return channel. A method involves moving a viewing instrument to or from a position near an optically transparent portion of a blunt, enclosed distal shaft end and a proximal side of an enclosed working area. A method also or alternatively involves changing a position of a fluid routing switch within the shaft. | 12-09-2010 |
| 20100331621 | Bipolar resection device having simplified rotational control and better visualization - An improved bipolar resection device provides an intuitive finger grip control in a smaller sheath package. Bipolar electrode wires occupy less space by extending in a closely abutting relationship along the sheath and exiting in a one above the other orientation that provides a reduced profile, allowing for better visualization during resection. In various embodiments, resection motion is provided through a rotational sweep transverse to the longitudinal axis of the resection device and may include push/pull motion. The sheath may be oval in shape and the bipolar electrode connected to the bipolar electrode wires having a narrow cross-section to improve resection site visualization. | 12-30-2010 |
| 20110004055 | UROLOGICAL RESECTOSCOPE FITTED WITH AN INSULATING ELEMENT AT ITS EXTERNAL STEM - A urological resectoscope ( | 01-06-2011 |
| 20120059219 | BIPOLAR RESECTION DEVICE HAVING SIMPLIFIED ROTATIONAL CONTROL AND BETTER VISUALIZATION - An oval or ovoid electrode is used in a resectoscope. A longer dimension of the electrode preferably extends in a direction that is perpendicular to the direction in which the electrode is moved during tissue resection. | 03-08-2012 |
| 20150351826 | BIPOLAR RESECTOSCOPE - A bipolar resectoscope has an inner shaft with an insulating insert at its distal end and an electrode transporter that can be arranged in the inner shaft. A first electrode is longitudinally moveable in the electrode transporter and has a proximal end that can be connected to a first connection of a high-frequency generator and a second electrode that can be connected at its proximal end to a second connection of the high-frequency generator. A circumferential electrically conductive electrode surface ( | 12-10-2015 |
