Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an endoscopy apparatus used for endoscopy.

[0002]

2. Description of the Related Art Generally, when performing an endoscopic examination, a light source device for supplying illumination light to the endoscope around a bed for a patient, and a high frequency ablation power supply device when performing a high frequency treatment. So that they do not interfere with the examination of the surgeon or the nurse,
It is placed with some spacing. An operator connects an endoscope, a treatment tool, and the like to these devices, and inserts, observes, and treats the endoscope into the body cavity.

By the way, since the endoscopic observation and treatment involve adjustment of the light source device and the high-frequency cautery power supply device, the operator conducts an examination in a standing state so that these adjustments can be performed easily.
In the examination in such a state, there is a problem that the operator is likely to feel a sense of pressure in addition to the problem that the fatigue of the operator increases due to the examination time taking a long time.

As described above, there is a demand for an endoscopic inspection apparatus which allows an operator to perform an examination while sitting from both the operator's standpoint and the patient's standpoint.

Therefore, for example, Japanese Patent Application Laid-Open No. 3-57423 is provided with an inspection chair in which at least one of a light source for supplying illumination light to an endoscope and a device used for inspection is integrally incorporated. Endoscopy devices have been proposed.

At the time of endoscopy, one end of the endoscope is inside the body cavity and the other end is connected to the light source and peripheral equipment. Since the light source and the peripheral devices move together with the chair when moving while performing an endoscopic inspection while sitting, the inspection can be continued without worrying about the positions of the light source and the peripheral devices.

[0007]

However, in the endoscopic examination, it is necessary to advance or retract the insertion portion or twist or change the patient's body position for the reason of insertion or examination procedure. The twisting motion of the part is an important motion and is frequently performed. When the insertion part is twisted in this way, the operation part of the endoscope provided on the proximal end side of the insertion part is also twisted, and air supply, water supply, suction, video,
The operation switches for shooting and bending will be located at the twisted position.

Therefore, when the operator stands up and conducts the examination, the operator needs to twist his body in order to ensure good operability of the switch of the operating portion, and in particular, the operator sits down as described above. When performing an inspection in a state, the operator cannot twist the body, and the operability of the switch is greatly deteriorated. Therefore, in reality, although the operator sits down and the examination is desired by both the operator and the patient, practically no examination is performed.

The present invention has been made in view of the above circumstances, and provides an endoscopy apparatus which reduces operator fatigue during endoscopy and has good operability of the endoscope. It is an object.

[0010]

Means and Actions for Solving the Problems: An endoscope insertion portion that is inserted into a lumen to obtain an endoscopic image; and an operation means that is connected to the endoscope insertion portion and operates the endoscope insertion portion. In the endoscopy apparatus including the endoscope, the operation means is provided at a position that does not follow the movement of the endoscope insertion portion, and the movement of the endoscope insertion portion is not transmitted to the operation means. The operator's fatigue in the examination is reduced and the operability of the endoscope is improved.
