曲げることになるので内容物の配置上好ましくない。FIG. 3 shows a hand operation unit of such an endoscope. FIG. 1 is a view of a state in which the grip 2 of the hand operation unit 1 is gripped by the left hand 3 of the operator, as viewed from the rear of the operation unit 4. The hand operation unit 1 shown in FIG. 1 has a structure in which the center axis 7 of the wrist is separated by a distance A with respect to a vertical axis 6 passing through the center of gravity 5 of the operation unit 4. It was applied to the base of the neck, imposing an unreasonable burden on the surgeon. Note that the above problem can be solved by shifting the position of the operation unit 4 so that the vertical axis 6 overlaps the center axis 7.
Is formed in a cylindrical shape, and the contents such as an air supply pipe, a water supply pipe, a suction pipe, a light guide, and an image guide are inserted into the inside thereof. This is not preferable in terms of the arrangement of the contents.

に構成されている。Therefore, a hand operation unit 10 shown in FIG. 4 has been proposed as a hand operation unit for solving such a problem. In the hand operation unit 10 shown in FIG. 1, a corner portion 12 of the outer peripheral portion of the grip portion 11 to which the base of the finger other than the thumb 8 abuts is formed to bulge, and is formed below the corner portion 12. The belly of the hand 3 is configured to contact the tapered surface 13.

When the user grips 1 with the hand 3, the center axis 7 of the wrist approaches the vertical axis 6 (a <A).
Accordingly, the weight of the operation unit 4 can be supported by the back 15 of the hand 3. As a result, the burden on the operator is reduced, and the endoscope can be operated for a long time. 3 and 4, reference numeral 16 denotes the gripping portions 2, 11.
Reference numerals 17 and 18 denote angle operation knobs provided on the operation unit 4, and reference numeral 19 denotes a suction button.

う欠点があった。However, the hand-operated portion 10 of the endoscope shown in FIG. 4 has a structure in which the corner portion 12 of the grip portion 11 is formed so as to protrude, so that the corner portion 12 and the angle operation knob 17 are not provided. There is a problem that the distance is longer than that of the hand operation unit 1 in FIG. Due to this problem, the hand operation unit 10 has a drawback that the index finger 20 of the hand 3 holding the holding unit 11 is difficult to reach the angle operation knob 17, and thus has a drawback that the angle operation is hindered.

It is provided to be. Further, according to the present invention, when the grip portion is gripped by the operator's hand, the angle of inclination of the grip portion is set to an angle at which the back of the hand can support the weight of the operation portion. When such a grip is gripped by the operator's hand, the central axis of the wrist approaches the vertical axis passing through the center of gravity of the operation unit,
The weight of the operation unit is applied to the belly of the hand, and the weight of the operation unit can be supported by the back of the hand. Thereby, the burden on the operator can be reduced. In addition, since the bulging portion is not formed in the corner portion of the gripping portion, the inconvenience that the index finger of the hand gripping the gripping portion does not easily reach the operation knob does not occur, thereby gripping the gripping portion. The operation knob can be operated by hand without any trouble.
