Embodiment approach

[0035] figure 1 It is a diagram schematically showing the overall configuration of an endoscope system according to an embodiment of the present invention. Such as figure 1 As shown, the endoscope system 1 of this embodiment has: an endoscope 2, which is introduced into the subject's body, photographs the subject's body to generate an image signal of the subject's body; The image signal captured by the endoscope 2 is subjected to predetermined image processing, and each part of the endoscope system 1 is controlled; the light source device 4 generates illumination light for the endoscope 2; and the display device 5 controls the information processed by the endoscope. The image signal processed by the device 3 is image-displayed.

[0036] The endoscope 2 has: an insertion portion 6 inserted into the subject; an operation portion 7 on the base end side of the insertion portion 6 for the surgeon to hold; and a flexible universal cable 8 connected from the operation portion 7 ex...

Abstract

To provide an endoscope system and an endoscope capable of accurately measuring the temperature of a distal end, controlling the temperature of optical components with high precision, and reducing the diameter of the distal end. The endoscope system of the present invention is characterized in that the endoscope system has: an optical component located at the front end; a heating component (13) that heats the optical component; a first temperature detection unit (11), It detects the temperature information of the front end; the second temperature detection part (12), which is connected in parallel with the heating part (13), detects the temperature information of the front end; the control part (43), which is based on the first temperature detection part (11) The detected temperature information of the front end portion controls the heating member (13); and the abnormality determination unit (42) is based on the temperature information of the front end portion detected by the first temperature detection unit (11) and the second temperature detection unit (12) The detected temperature information of the tip portion is used to determine the abnormality of the first temperature detection unit (11) and the second temperature detection unit (12).

Description

technical field [0001] The present invention relates to endoscopic systems and endoscopes. Background technique [0002] Conventionally, an endoscope that is inserted into a subject to observe a site to be examined is known, and the endoscope is widely used in the medical field and the like. Since the endoscope is used in the body where the humidity is high and the temperature is higher than room temperature, when the front end of the insertion part is inserted into the body, the optical components such as the lens cover and the objective lens arranged at the front end may be fogged, making it difficult to obtain a clear view. Image. [0003] In order to solve this problem, the following endoscope apparatus has been proposed: the heating member and the first temperature sensor are arranged in contact with the objective lens, the second temperature sensor is arranged on the side opposite to the illumination lens through the objective lens, and the heating element is heated. ...
