Disposable two-step endoscope

A disposable two-step endoscope for examining organs of a human body, comprising:

• an image capturing and transmission device, including:
• a body;
• a luminous device located in the body to provide light that projects on the organs of the human body;
• an optical image capturing device located behind the luminous device to convert light reflected off the organs to an electric signal;
• a wireless transmitter having a circuit connected to the optical image capturing device to transmit the electric signal outside the human body;
• an internal power supply located in the body having another circuit connected to the body, the luminous device, the optical image capturing device, and the wireless transmitter to provide electric power;
• a disconnection shell attached to a rear of the body, the disconnection shell having a steel ball trough formed therein;
• and
• a leaf spring electrically connected to at least the luminous device and the optical image capturing device, the leaf spring being engageable with the steel ball trough;
• a cable removably connected to the disconnection shell to channel an external power supply and transmit the electric signal via the leaf spring, and having a disconnection mechanism which is coupled with the disconnection shell to control connection and disconnection between the cable and the image capturing and transmission device, the cable further having a flexible hose which is made from a material compatible to the human body, the flexible hose having the disconnection mechanism disposed therein, the disconnection mechanism including a steel ball, the flexible hose being latched to the disconnection shell by pressing the steel ball against the leaf spring and into the steel ball trough, the image capturing and transmission device being electrically connected to at least the external power supply via the leaf spring and the flexible hose.
