A portable surgical training device is provided. The trainer includes a top cover spaced apart from a base to form a simulated body cavity for locating model organs that are substantially obscured from the field of view of the user. The top cover includes a video display, fixed insertion ports and interchangeable inserts containing simulated tissue layers. The training device has open sides for demonstrating and training lateral surgical techniques including a simulated or live tissue colon attached to a support leg for simulating transanal minimally invasive surgery. A training endoscope with an adjustable focal length for use with the trainer and, in particular, with optical trocars is disclosed. The surgical trainer can be angled and is well suited for training laparoscopic surgery techniques and demonstrating surgical instruments.

Portable laparoscopic trainer

A cannula assembly includes a tubular element forming a lumen, a deployable element of a subassembly, and an electronic component mounted to the deployable element. The tubular element has a proximal end and a distal end adapted to be inserted into a body cavity. The deployable element is coupled through the subassembly to the tubular element, and is adapted to transition between a closed position and an open position. The electronic component has at least one imaging device and at least one illumination source. The subassembly, including the deployable element and the electronic component, are releasable from the tubular element.

Cannula with integrated camera and illumination

A system and method adaptively control sensitivity, on a pixel-by-pixel basis, of a digital imager. An illumination intensity level mapping controller determines a number of pixels of image data having illumination intensity levels within a first defined range of illumination intensity levels and determines an illumination intensity level mapping function based upon the determined number of pixels within the first defined range of illumination intensity levels. An exposure controller determines a number of pixels having illumination intensity levels within a second defined range of illumination intensity levels and determines an integration time based upon the determined number of pixels having illumination intensity levels within the second defined range of illumination intensity levels. A transfer control function generation circuit determines a composite transfer control function based on the determined integration time and determined illumination intensity level mapping function; determines each transition point between a plurality of discrete transfer control functions from the determined integration time and the determined illumination intensity level mapping function; and imposes the determined transfer control function upon a pixel of the digital imager.

Adaptive sensitivity control, on a pixel-by-pixel basis, for a digital imager

A method and apparatus for enhancing the contrast of an image. The method may include creating a histogram of an original image, determining output pixel values based on one or more thresholds that define a minimum number of pixels in each histogram bin, and correcting the original image using the output pixel values.

Algorithm to enhance the contrast of a monochrome image

An area is imaged with a non-standard aspect ratio, e.g. wide aspect ratio, digital imager to produce pixels of image data. At least a portion of the produced pixels of image data corresponding to the captured non-standard aspect ratio image is displayed beginning, for a given frame of pixels of image data, at a column of pixels of image data corresponding to a predetermined column of imaged pixels. The number of columns of display pixels is different than the number of columns of imaged pixels. Motion is detected in the imaged pixels so that a motion responsive portion of the imaged pixels corresponding to the captured non-standard aspect ratio image corresponding to a window of the imaged pixels having motion detected therein can be displayed.
