Problems solved by technology

In particular, in an electronic endoscope device having an imaging device corresponding to a high pixel at the front end of the insertion portion, there is a problem that the outer diameter of the insertion portion must be increased by the amount that the communication cable becomes thicker, thereby obstructing the insertion portion. thinning
[0009] For example, in order to shorten the distance from the video processor to the camera, the camera disclosed in Japanese Patent Application Laid-Open No. 2006-15078 can be integrally installed in the interior with a curved portion disclosed in Japanese Patent Laid-Open No. 10-234654. However, if this is done, the camera and the sprocket linked to the bending operation knob for bending the bending part will be built in, so the operating part will become larger
[0010] In particular, for female physicians with smaller hands than male physicians, if the operating unit is enlarged, it will be more difficult to hold and operability will be worse.

Abstract

An electronic endoscope apparatus 2 includes: an image pickup apparatus 21 mounted at a distal end portion 6 of an insertion portion 9; an operation portion 10 provided consecutively at the insertion portion, with a frame member 30 incorporated therein; and an electrical cable 17 extended from the operation portion for connection with an external device 4. In the electronic endoscope apparatus, the frame member has a circuit board portion 31 which establishes electrical connection between shields of the insertion portion and the electrical cable, and on which various electronic parts for exchanging signals with the image pickup apparatus are mounted. In spite of the arrangement of the image pickup apparatus that can acquire high-quality images at a distal end portion of the insertion portion, a size of the apparatus, in particular, a diameter of the insertion portion, can be prevented from being increased.

Description

Technical field [0001] The present invention relates to an electronic endoscope device having a solid-state imaging element at the tip. Background technique [0002] In recent years, endoscopes have been widely used in medical and industrial fields. Among conventional endoscopes, endoscopes that use an image guide and can observe the patient's body cavity or the inside of a jet engine by the user through the eyepiece portion for peeking are the mainstream. In addition, the following electronic endoscope devices have appeared in recent endoscopes: they are equipped with an imaging device that takes pictures of the patient's body cavity or the inside of a jet engine, and displays the endoscopic image on an external monitor, etc. In the display device. [0003] Regarding the technology of using an imaging device in an endoscope, for example, as described in Japanese Patent Application Laid-Open No. 2006-15078, the following medical device is proposed: a camera head with a built-in C...
