[Detailed Description of the Invention] [Industrial Field of Application] This invention provides an endoscope device that allows an operator and an assistant to work freely in an endoscopy room and allows for efficient examinations. It is related to.

[Prior Art] In a conventional endoscope device, a light source device is placed on the floor of an examination room, and the operator grasps the endoscope body and connects the light source device with the light source device using a connecting tube through which a light guide fiber is inserted. It was connected to the endoscope body.

[Problems to be Solved by the Invention] Generally, when performing an endoscopy, the operator frequently rotates the endoscope body according to the observation direction, and the assistant uses the imaging device and the To operate or replace tools, etc.
It constantly walks around the caster. Therefore,
In order to perform endoscopy smoothly and efficiently, it is important that the endoscope body can be easily rotated and that assistants can move freely around the surgeon. .

However, in the conventional endoscope device described above, the light source device is placed on the floor, and the endoscope body held by the operator and the light source device are connected by a connecting tube. If you try to rotate the endoscope body, the connecting tube will twist and interfere with the rotation operation, and if an assistant tries to walk around the surgeon, he or she may get caught in the light source device or the connecting tube. They were unable to walk around freely, which was a major obstacle to operating treatment instruments and other auxiliary operations.

The purpose of this invention is to eliminate such conventional drawbacks and provide an endoscope device in which the main body of the endoscope can be freely rotated and an assistant can act freely. shall be.
