Endoscopic devices are disclosed for viewing and/or performing a surgery on a patient's organ, such as a uterus. In an embodiment, the endoscopic deice includes a housing, a cannula, an imaging system, and a flexible printed circuit (FPC). The cannula is configured for insertion through a cervix into a uterus. The cannula has a lumen that extends from a proximal end of the cannula to a distal end of the cannula. The proximal end of the cannula is secured within the housing. The imaging system is located at a distal end of the cannula and includes a camera and one or more light-emitting diodes (LEDs). The FPC extends within the lumen of the cannula and electrically connects the camera and the LEDs to electrical components located in the housing. The lumen is configured to provide a passage for a working tool.
