  • Patent number: 9782566
    Abstract: The present invention is an access sheath comprising a tube or sheath with a passageway primarily for endoscopic procedures accessing the ureter through the bladder. The sheath has a bend limiting feature to limit the bend angle or bend radius. The sheath exhibits flexibility up to this limit at which point it becomes rigid. Excessive force is required to bend the sheath beyond the bend limit and would result in the kinking of the tubular frame.

  • Patent number: 9770230
    Abstract: Components for an endoscopic vessel harvesting system suitable for harvesting target vessels such as the saphenous vein or radial artery for cardiac artery bypass graft surgery. The main components of such systems include a vessel dissector and a vessel harvester, both of which work in conjunction with a separately provided endoscope. The vessel dissector is an elongated cannula having a blunt tip for separating layers of facial around vessels. The tip may be movable, and is typically transparent to permit viewing forward of the tip using the endoscope. Internal features of the tip may reduce glare back to the endoscope. Several devices improve visibility through the tip by reducing interference from tissue or fluid on the tip. The vessel harvester also has an elongated cannula for receiving the endoscope. Several tools within the harvester permit manipulation, severing, and sealing of vessels forward of the distal end.

  • Patent number: 9763561
    Abstract: An attachment unit rotates in directions around a longitudinal axis with respect to an insertion main body when rotary drive force is transmitted from a drive force transmission unit provided to an insertion section, and allows propulsive force in one of directions parallel to the longitudinal axis to act on the insertion section by rotating in contact with a paries. The attachment unit includes a fin portion which is spirally extended along the longitudinal axis and whose dimension from the longitudinal axis to an outer peripheral end vary in accordance with how external force different from the propulsive force acts in the directions parallel to the longitudinal axis in a state that the attachment unit does not rotate with respect to the insertion main body.

  • Patent number: 9759903
    Abstract: A drying agent arrangement for optical instruments, in particular for endoscopic instruments, having a hygroscopic substance in the instrument housing, such that the hygroscopic substance, configured as individual molded bodies, is positioned in an intake receptacle that can be replaceably inserted in the instrument housing. To provide a drying agent arrangement that, along with simple, versatile application, allows the intake of a great quantity of drying agent, the intake receptacle may be configured as a double-walled sleeve, such that the two walls, forming an intake space for the molded bodies of the hygroscopic substance, are radially distanced from one another and positioned in such a way that the walls, closing the intake space at one axial end of the sleeve, are connected with one another at the end and on the other axial end of the sleeve, releasing the intake space, are radially distanced from one another at the end.

  • Patent number: 9649020
    Abstract: A control assembly for manipulating the movement of an endoscopic instrument includes an endoscopic instrument mounting arrangement adapted to receive an endoscopic instrument, three driving arrangements, and three independent control elements. The mounting arrangement offers only three independent degrees of freedom of movement of an endoscopic instrument received by the arrangement, each degree of freedom of movement being about or along a respective axis. Each of the three driving arrangements are configured to drive the endoscopic instrument in only one of the degrees of freedom of movement. The three independent control elements are configured to receive user input, such that the actuation of each of the three independent control elements regulates one of three corresponding control signals, each control being a respective one of the driving arrangements independent of the other two driving arrangements in accordance with the user input.
