An endoscope, cannula, and obturator. The endoscope has a handle and an insertion shaft. The insertion shaft has a solid state camera. The handle contains a circuit board with circuitry for control of and receipt of signals from the camera. The handle and its components are formed of biocompatible materials. The handle is formed of inner and outer shells concentric with each other, rotation of the shells relative to each other controlled via one or more resilient components frictionally engaged between the respective shells. The handle has no metal fasteners, no adhesives, and no detachable parts small enough to travel though fluid passages of the insertion shaft, except those encapsulated by overmolding or melt-fusing to prevent dislodgement. The cannula has a connector and locking feature designed to engage with mating connectors and locking features of the obturator and the endoscope, both successively.

An endoscope comprises a light splitting device for transmitting a first illuminating light and reflecting a second illuminating light emitted by a light source. The first illuminating light passes through a first color filter transmitting a first color. The second illuminating light passes through the second color filter transmitting a second color. The first color is different from the second color. The light splitting device combines a first incident light of the first color and a second incident light of the second color. The first incident light of the first color and the second incident light of the second color pass through an imaging lens and form images of the first color and the second color on an image sensor, respectively. A CFA (color filter array) comprising a plurality of first CFA components of the first color and a plurality of second CFA component of the second color covering the image sensor.

The present invention relates to a fully integrated sterilizable one time use disposable tissue visualization device and methods for using such devices. Preferred embodiments of the invention facilitate the visualization of an internal tissue site while ausing a minimum of damage to the surrounding tissue. Further preferred embodiments may allow for the delivery of fluids and other treatment to an internal tissue site.

Single viewpoint panoramic imaging attachments for a colonoscope are disclosed that are compact in size and provide 360-degree side and rear-views in a single image. One panoramic attachment assembly includes a plurality of micro-imaging subsystems that are positioned around a central opening. Each micro-imaging subsystem includes a reflector to receive light that is reflected from a surrounding tissue, an imaging lens, and a detector to generate signals corresponding to one section of a panoramic image of the surrounding tissue. The micro-imaging subsystems are arranged to all have a common view point, and are configured to collectively form a full 360-degree image of the surrounding tissue.

An arthroscope's insertion shaft has near its distal end a solid state camera. The shaft has an outer diameter of no more than 6 mm, and has rigidity and strength for insertion of the camera into joints for arthroscopic surgery. Light conductor(s) have a flattened region shaped to lie between an endoscope camera and an inner surface of an outer wall of an endoscope shaft. The flattened region is shaped to conduct illumination light though the space between the camera and inner surface of the other wall to a distal end of the endoscope shaft for illumination of a surgical cavity to be viewed by the camera. The flattened region is formed by heating a region of a plastic optical fiber, and squeezing the heated region in a polished mold.

This invention relates generally to a medical device, and more specifically, to a vaginal surgical apparatus. In one embodiment, a vaginal device includes, but is not limited to, a shaft, the shaft including at least a space to at least partially accommodate a cervix; and a slot to secure a tenaculum; and a stopper that is positionably adjustable along at least a portion of a length of the shaft.

A direct vision cryosurgical and methods of use are described herein where the device may generally comprise an elongated rigid structure with a distal end, a proximal end, and a central lumen. The distal end may comprise a non-coring optically transparent needle tip with at least one lateral fenestration in communication with the central lumen. The distal end may also house at least one imaging device configured for distal imaging. A proximal end of the device may comprise a handle with a means for connecting the imaging device(s) to an imaging display(s), and a means for accessing bodily tissue in the vicinity of the distal end with a cryo-ablation probe through the central lumen and the lateral fenestration(s) for diagnostic or therapeutic purposes.

A sensor device, in particular a sensor head, for an inspection camera, in particular an endoscope, has at least one illumination unit for illuminating an examination object. The sensor device further has at least one camera unit for detecting the examination object. In addition, the sensor device has at least one housing unit in which the camera unit and the illumination unit are arranged. The housing unit is designed to taper along a longitudinal axis of the housing unit.

An endoscope system includes a shaft portion having a proximal end and a distal end and defining a longitudinal axis. The system also includes a first image receiver coupled to the shaft portion. The first image receiver is directed toward a first direction to receive an image of a first portion of the interior of a lumen. The system also includes a second image receiver coupled to the shaft portion. The second image receiver is directed toward a second direction to receive an image of a second portion of the interior of the lumen. The first direction is generally opposite the second direction. The system further includes a monitor, wherein the image of the first portion and the image of the second portion are displayed simultaneously on the monitor.

An imaging device (010, 10, 110) comprises a first optical system (020, 20, 120) at a distal end of the imaging device, a second optical system (080, 80, 180) towards the proximal end of the imaging device, and a sensor (074, 74, 174) at the proximal end of the imaging device. The first and second optical systems and the sensor are aligned along a common longitudinal axis. The first optical system is or comprises one or more reflective and/or refractive optical components (24, 124; 22, 122) symmetrically and/or coaxially arranged with respect to the longitudinal axis, and the second optical system comprises one or more reflective and/or refractive optical components (24, 124; 22, 122) for focussing incident light towards the sensor. A calibration system (200) and method for calibrating such an imaging device, and a method of processing image data obtained from such an imaging device are also provided.
