DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shirt release device for an endoscope camera that performs a shirt release operation when the endoscope camera is used by being attached to an endoscope.

When using an endoscope camera attached to the eyepiece of a medical endoscope, the user, such as a doctor, generally holds the operating section of the endoscope with his left hand and uses his index finger to He operates the endoscope's suction button, and uses his middle finger to operate the endoscope's air and water supply buttons. In addition, the right hand can be used to grasp an appropriate part of the endoscope's body cavity insertion part to guide the tip of the insertion part to the target site in the patient's body cavity, or to use the endoscope's curved knob. to guide the tip of the insertion tube to the desired affected area. The patient's affected area inside the body cavity is then observed through the viewfinder of the endoscope camera and photographs are taken.With conventional systems, when the user encounters the desired location and presses the camera's release button, To do this, as described above, move the right hand that operates the curved knob or grasps the insertion section and guides the tip of the endoscope to the imaging site away from the curved knob or the insertion section, Since you have to move to the camera's shutter button and press the shutter button, there are the following drawbacks. In other words, the human body cavity is constantly moving due to the heartbeat and the oscillation of the lumen, so as mentioned above,
If you remove your right hand from the endoscope's curved knob or the insertion tube, move it, and then press the shoot button, the affected area of the subject will move during this time, and you will miss the photo opportunity, and you will have to take the trouble to move the tip of the endoscope. Even if the engine is guided to the optimum state, the shutter cannot be turned off quickly, and the operation is complicated.

Therefore, in order to eliminate such drawbacks, a release lever is pivoted on the outer peripheral surface of the endoscope attachment part on the endoscope camera side, and the release operation is performed via this release lever. A method has been proposed that allows the release operation to be performed without taking one's hand off the mirror's operating section.

However, in this method, the finger rests of the release lever are arranged so that the operation part of the endoscope can be operated with either the thumb or index finger of the left hand that grips it. It may be difficult to operate depending on individual differences and usage conditions. Normally, it is designed to be operated with the thumb, but in this case, it cannot be operated at all with the index finger of the left hand, and if it is combined with an endoscope with an orcus mechanism, it is very convenient to operate it with the index finger of the right hand. However, these demands could not be met.

The present invention has been made in view of the above-mentioned circumstances, and the purpose of the present invention is to attach a camera to an endoscope and use the camera to perform operations such as insertion, angle, and focusing of the endoscope. To provide a release device for an endoscope camera, which allows a shutter release operation to be easily performed under optimal conditions.
