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.
