Abstract

In this endoscope 1, the temperature of an endoscope connector 5 to be connected to a processor 10 is appropriately controlled by installing, on a connector substrate 8 of the endoscope connector 5, atemperature sensor 34 for directly measuring the temperature of the connector substrate 8, and performing control to restrict the power supply from an endoscope power supply source circuit 33 (namely, limit and stop the power supply) on the basis of the measured temperature of the connector substrate 8 (namely, that of the endoscope connector 5).

Description

technical field [0001] The present invention relates to an endoscope and an endoscope system having a connector detachable from an external device. Background technique [0002] Conventionally, endoscopes capable of observing internal organs and the like in body cavities by inserting a long and thin insertion portion into body cavities have been widely used in the medical field. [0003] In such endoscopes, it is particularly necessary to take countermeasures against heat generation at the tip portion. In this regard, for example, Japanese Unexamined Patent Publication No. 2013-27418 discloses a technology in which a first circuit unit is built in the front end of an endoscope, and the first circuit unit includes an imaging device having an imaging element and its peripheral circuits, and a The first regulator of the power supply circuit has a second circuit part (connector board) built into the connector of the endoscope, and the second circuit part includes a second regul...
