Problems solved by technology

Since the endoscope is used in the body where the humidity is high and the temperature is higher than the 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, and a clear view may not be obtained.

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

Provided are an endoscopy system and endoscope that accurately measure the temperature of a distal end and precisely control the temperature of an optical member, and allow for the distal end to be reduced in diameter. The endoscopy system according to the present application is characterized by comprising: an optical member positioned at a distal end; a heating part 13 for heating the optical member; a first temperature-detecting part 11 for detecting temperature information for the distal end; a second temperature-detecting part 12, connected in parallel with the heating part 13, for detecting temperature information for the distal end; a control part 43 for controlling the heating part 13 on the basis of the temperature information for the distal end as detected by the first temperature-detecting part 11; and an anomaly-identifying part 42 for identifying anomalies in the first temperature-detecting part 11 and the second temperature-detecting part 12 on the basis of the temperatureinformation for the distal end as detected by the first temperature-detecting part 11 and the temperature information for the distal end as detected by the second temperature-detecting part 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. ...
