Endoscope system with multiple connection interfaces to interface with different video data signal sources
Endoscopes having a tip section with viewing elements coupled to a CMOS image sensor and/or a CCD image sensor for transforming light captured by the viewing element into digital and/or analog signals are described. A main connector is coupled with the tip section for transmitting the signals to a main control unit of the endoscope. The main connector includes a pad for transmitting digital signals provided by the CMOS image sensor to a push pin probe in a receptacle of the main control unit. The main connector also include another interface for transmitting analog signals to the main control unit.
1. An endoscope system comprising:
an endoscope comprising:
a tip section having at least one viewing element;
a main connector coupled with the tip section and configured to receive and transmit a first set of video data signals from the at least one viewing element wherein the main connector comprises at least one pad; and
a control unit comprising:
a receptacle positioned on an exterior surface of the control unit and configured to receive the main connector, wherein the receptacle has a first region, wherein the first region comprises at least one probe, wherein said at least one probe comprises a spring loaded pin, and wherein, upon attachment of the main connector to said receptacle, the at least one probe abuts the at least one pad such that the at least one probe is compressed;
wherein the receptacle further comprises a second region, wherein said second region comprises a multi-pin interface configured to receive a second set of video data signals, and wherein the second set of video data signals have a lower bandwidth than a bandwidth of the first set of video data signals.
