  • Patent number: 11116586
    Abstract: Systems and methods for controlling an elongate device include an input control console. The console includes a first input control having an infinite length of travel in a first direction, a second input control having an infinite length of travel in more than one direction, one or more transceivers for coupling the console to a control unit for the elongate device, and interface circuits for coupling the first input control and the second input control to the one or more transceivers. The first input control provides a first command suitable for controlling an insertion depth of the elongate device. The second input control provides second commands suitable for controlling steering of a distal end of the elongate device. In some embodiments, the console includes raised rings or bezels within which the input controls are mounted. In some embodiments, pockets of a drape are anchored to the raised rings or bezels.

  • Patent number: 10986321
    Abstract: A device and method for color correction of two camera systems each having an imaging device and an illumination source. The camera systems are separately white balanced with the imaging device outside a scene. Their white balance gains and color correction matrices are saved. Based on the measurements, combined white balance gains and combined color correction matrices are computed and saved. Thereafter, with the imaging devices in a scene, performing white balancing by measuring the R, G, and B values of both imaging devices together, and then white balancing by measuring the R, G, and B values of each separate imaging device with the other camera system's light off. Comparisons are made of each camera's scene measurements against the combined scene measurements. If they are significantly different, the combined light set of white balance gain and color correction matrix is applied to digital signal processing paths of each camera system.

    Abstract: A continuous flow irrigation endoscope and a continuous flow irrigation fluid management system, both designed to be compatible to each other and to function as a single system. The endoscope and the fluid management system are synergistic to each other such that both enhance the efficiency of each other. The invented system allows a body tissue cavity to be distended by continuous flow irrigation so that detached tissue pieces and waste fluid present inside a body tissue cavity are continuously automatically evacuated from the tissue cavity without causing the cavity to collapse at any stage and without the need of withdrawing the endoscope of a part of the endoscope from the tissue cavity. No type of feedback mechanism, such as mechanical or electrical, or valve or valve like systems, are incorporated in the endoscope to influence or facilitate the removal of detached tissue pieces or waste fluid in any manner.

    Abstract: The present invention relates to an endoscope, in particular an ureterorenoscope. The endoscope comprises a lumen for insertion of a light and energy transmitting fiber. According to the invention during insertion of the fiber into a working channel of the endoscope the sharp edges of the fiber are protected by a flexible sleeve in order to avoid damages of a wall limiting the working channel. Prior to using the fiber for transmitting energy emitted by a laser the flexible sleeve is completely removed from the working channel in order to free a lumen that might be used for additional instruments or delivery of a fluid. Furthermore the stiffness of the endoscope is reduced by removing the flexible sleeve.

The lumen of a medical device such as a catheter to be cleaned is first brushed with the brush end of a cleaning device selected to approximately match the lumen diameter. After brushing, the device is reversed, or preferably simply pushed through the lumen to be cleaned, and the swab end is used to remove any film remaining after the brushing. In a preferred method of cleaning, the brush end of the cleaning device is inserted into an end of the lumen to be cleaned, and pushed through only once, to avoid recontamination of the lumen by matter remaining on the brush.

  • Patent number: 5893878
    Abstract: An apparatus for surgically manipulating tissue without causing irreparable damage to the tissue during retention and manipulation is disclosed. The tissue manipulator apparatus includes a shaft having proximal and distal ends, a rod member with proximal and distal ends circumferentially contained within the shaft, a contact member having at least one tissue contact surface area comprising a plurality of projections connected to the distal end of the rod member, and a handle member attached near the proximal end of the shaft. The plurality of projections preferably point in the direction of retraction of the targeted tissue. The apparatus is designed to distribute the interdentating contact over the tissue micro surface area in an effort to reduce reliance on pressure induced friction alone.

  • Patent number: 5503616
    Abstract: A channel system for use with a conventional endoscope is provided. The system comprises a collapsible access channel that is connected to a first distal end of the endoscope. The collapsible channel includes an access opening communicating between the two ends of the collapsible channel. The endoscope may be provided with a protective sheath and/or an endcap that is integral with the collapsible channel. The collapsible access channel allows a physician to insert functional instruments such as a biopsy device or tubes for supplying air, water, suction and irrigation.

  • Patent number: 5448990
    Abstract: An improved endoscope assembly for exploratory and general surgery which permits exceptional vision while eliminating the requirement of both washing of the lense and expansion of the body cavity. Using a standard endoscope, a housing is placed over the end of the endoscope. The housing is equipped with a window for viewing through by the endoscope's viewing tip. The window is arranged at an angle different from the angle of the viewing tip so that light is reflected back into the housing, and not into the viewing tip. The interior of the housing is coated with a light absorbing material to eliminate back-scattering of light into the viewing tip of the endoscope which degrades the endoscope's vision. An air-chamber between the viewing tip of the endoscope and the window assures the crispest vision possible. Further, fogging of the window is eliminated through the use of heating wires, dry gases, or the like so that the endoscope is also useful for cadaver lessons.
