Abstract: A handheld surgical endoscope has a disposable, single-use handle, cannula and an imaging module at a distal tip. A multiple-use display unit is removably mounted on and supported by the handle and includes a touch-sensitive display screen configured to respond to touch commands to control taking of images with the imaging module and further configured to display the images. The display unit and the handle include respective mechanical connectors that engage each other to removably mount the display unit on the handle by sliding motion relative to each other, and the display unit is removable tool-free from said handle for disposal of the handle and cannula after a medical procedure therewith.

Abstract: A handheld endoscope has a disposable, single-use portion that includes a fluid hub, cannula, distal tip and is steerable by the operator though actuation of one or two levers. The endoscope also includes re-usable portion that has a handle and display module. The distal tip includes LED illumination and an imaging module that feeds live video to the display module that is rotatable to allow viewing by the operator and others. The single-use and re-usable portions mate and un-mate with each other via physically separated mechanical and electrical connectors. The single use portion can include grasper device that can be actuated by an operator using an actuation tab.

Abstract: A handheld surgical endoscope has a disposable, single-use handle, cannula and distal tip. The distal tip includes LED illumination and an imaging module that feeds live video to a re-usable display module that connects off-axis to the disposable handle. A rechargeable battery module also attaches to the handle. The cannula includes two lumens for separate fluid in-flow and out-flow channels, as well as providing a working channel through which a surgical implement can be used. Extruded cannula and molded distal tip parts can be separately formed which aids in manufacturing and assembly. The working channel can have a substantially straight proximal access port.

Abstract: A handheld surgical endoscope has a disposable, single-use portion that includes a and a re-usable portion that includes a handle and display module. The distal tip includes LED illumination and an imaging module that feeds live video to the display module. The imaging module includes a lens system of no more than two lenses and provides the imaging module with a field of view greater than 120 degrees, preferably 130 degrees or more, and most preferably 140 degrees or more. LED illumination is provided by plural LED arranged symmetrically around an optical axis to provide a field of illumination that substantially coincides with the field of view of an imaging module. An image brightness balance arrangement selectively varies the illumination provided by different LEDs to reduce brightness differences between different areas of the displayed images.
