In one embodiment, the control unit automatically identifies the medical device and automatically adjusts its settings to control the medical device, where the device and power transceivers may be provided detachable from either or both the endoscope/camera and camera control unit or may be provide integral to either one or both.

Abstract: A system for wirelessly powering various devices positioned on an endoscope, including, for example, a light source, various electronics including an imager and/or a memory device. The system is further provided such that video signal processing parameters are automatically set for an endoscopic video camera system based upon characteristics of an attached endoscope, with reduced EMI and improved inventory tracking, maintenance and quality assurance, and reducing the necessity for adjustment and alignment of the endoscope and camera to achieve the data transfer.

Abstract: A swing prism endoscope with an actuating mechanism that comprises a control element that oscillates in between proximal and distal ends of the endoscope and is coupled to a distally mounted swing prism, a control surface with a variable profile, and an engaging element that contacts the control surface and moves relative to the control surface while contacting the control surface causing the control element to oscillate. The distally mounted swing prism that alters the viewing angle of the endoscope between a forward direction that is substantially parallel to the longitudinal axis of the endoscope and a side direction that is angled relative to the longitudinal axis of the endoscope.

Abstract: An endoscope with a wide angle lens that comprises an optical axis that is angularly offset from a longitudinal axis of the endoscope such that the optical axis resides at an angle greater than zero degrees to the longitudinal axis. The wide angle lens system simultaneously gathers an endoscopic image field at least spanning the longitudinal axis and an angle greater than ninety degrees to the longitudinal axis. The endoscope further includes an imager comprising an imaging surface area that receives at least a portion of endoscopic image transmitted by the wide angle lens system and produces output signals corresponding to the endoscopic image field and image forming circuitry that receives the output signal and produces an image signal.

Abstract: A method for presenting an indicator of the upright orientation of an endoscopic image. An electronic rotation pick-up means is fixed to the housing of an endoscope. The electronic rotation pick-up means produces signals indicating rotations of the endoscope. A microprocessor uses these signals to calculate the difference between the upright image orientation and the actual image orientation. The calculation includes factors to account for endoscope roll, endoscope pitch, and endoscope viewing direction. The upright indicator is displayed on a video display device along with the endoscopic image.

Abstract: A method and system are provided for configuring a variable direction of view endoscope, generally comprising a video display screen and an endoscope having a view controlling device for moving the view vector between predefined, discrete view vector positions. The video display screen displays a set of these view vector positions, and the view vector is moved from one of these positions directly to another in response to a command from a user via the video display screen.

Abstract: A method for capturing and displaying endoscopic maps is disclosed generally comprising providing an endoscope with a view vector that pivots relative to the longitudinal axis of the endoscope, programming a scan trajectory along which the view vector moves relative to the longitudinal axis of the endoscope to provide a redefined sequence of views of a surface, and capturing a sequence of images corresponding to the predefined sequence of views as the view vector moves along that scan trajectory. A set of configuration coordinates is associated with each of the captured images, and the images and the coordinates associated therewith are used to create a map of the interior surface that is larger than the view attending the view vector.

Abstract: A variable direction of view endoscope generally comprising an endoscope shaft, an objective optical system disposed in the distal end of the shaft that defines a view vector movable relative to the longitudinal axis of the shaft, and a viewing window located in the distal end of the shaft through which the view vector scans over a range of different view vector directions when moved relative to the longitudinal axis of the shaft. A portion of the distal section of the endoscope shaft adjacent and proximal to the viewing window has a cross-section perpendicular to the longitudinal axis of the shaft, and at least two regions within the cross section are connectable by a straight line that does not lie within or on the boundary of the cross section. In certain embodiments, cross section comprises at least two disjoint closed sets of points.

Abstract: A method is disclosed for displaying endoscopic images that includes three-dimensional surfaces, variable viewing points, directions, and orientations. A computer receives a captured endoscopic image. A virtual surface is defined in the computer with the captured image textured onto the virtual surface. A virtual viewing point, virtual viewing direction, and virtual viewing orientation are defined relative to the virtual surface. A rendered image of the virtual surface is then created. The rendered image is displayed to the user. Video is displayed on the virtual surface by updating the image texture with each new frame.

Abstract: A method is disclosed in for presenting an endoscopic image in an upright orientation. An electronic rotation pick-up means is fixed to the housing of an endoscope. The electronic rotation pick-up means produces signals indicating rotations of the endoscope. A microprocessor uses these signals to calculate a necessary amount of rotational correction for the endoscopic view orientation. The calculation includes factors to account for endoscope roll, endoscope pitch, and endoscope viewing direction. An image rotator rotates the endoscopic image by the calculated correction amount. The rotated image is displayed on a video display device.
