つた。 Generally, an endoscope has an insertion section and an operation section, and the operation section is provided with an angle knob used to bend the insertion section. This angle knob is operated with the thumb of the left hand that grips the operating section, and at this time, a rotational force centered on the longitudinal axis of the operating section is applied to the operating section. As a result, the operating section gradually rotates even when gripped, making it difficult to operate the angle knob.
本考案は上記事情に着目してなされたもので、
その目的とするところはアングルノブの操作に起

て配置されている。 Reference numeral 1 in FIG. 1 indicates an endoscope, and this endoscope 1 consists of an insertion section 2 and an operating section 3 connected to the proximal end of the insertion section 2. The operating section 3 has an outer shell made of plastic and is integrally molded. Various configurations are incorporated into the operating section main body 4 using the relatively long shape. The operating section main body 4 has a proximal end 6 to which the eyepiece 5 is attached, an insertion section end 7 that connects the insertion section 2, and a grip that the operator holds with one hand (in this embodiment, the left hand). 8, and the front and left and right side parts of the proximal end 6 are connected to the other insertion part side end 7 and gripping part 8.
It is formed to protrude and be larger than the width of the For this reason, a rising wall 9 is formed at the proximal end 6 by a stepped portion formed between the proximal end 6 and the grip portion 8. Further, as shown in FIG. 2, the grip portion 8 has a substantially rectangular cross-sectional shape with rounded corners. Note that there is no step between the grip portion 8 and the insertion portion side end portion 7, and the grip portion 8 and the insertion portion side end portion 7 are formed substantially continuously. Further, a light guide cable 10 is connected to a rear portion of the right side of the proximal end portion 6 . Furthermore, a carbon dioxide gas supply operation button 12, a suction operation button 13, and an air/water supply operation button 14 are provided side by side on the front wall of the proximal end portion 6. Further, a protruding portion 16 having a treatment tool opening 15 for inserting and removing a treatment tool such as forceps into and out of the insertion channel in the endoscope 1 is integrally provided on the insertion portion side end portion 7 . That is, the gripping portion 8 is located between the protruding portion 16 and the rising wall 9.

る。 As shown in FIG. 2, this gripping portion 8 is gripped with one hand (left hand) of the operator, and the part that touches the palm of the hand and the part that touches the fingertips have anti-slip protrusions 17 and 18, respectively. is provided. As shown in FIG.
Consisting of 9..., 20..., these protrusions 19..., 2
0... are arranged parallel to each other. In addition, the number of protrusions 19 of the protrusions 17 that correspond to the palm of the hand is large, for example seven, and they are provided over a wide range, whereas the protrusions 19 that are provided in the part that corresponds to the fingertips are large.
The number of protrusions 20 of No. 8 is small, for example three, and they are provided over a narrow range. moreover,
The height h 1 of the protrusions 19 of the protrusions 17 that touch the palm of the hand is formed lower than the height h 2 of the protrusions 20 of the protrusions 18 that touch the fingertips, so that the stimulus given to the palm is not too strong and causes pain. It is set as. Note that the protrusion 18 that corresponds to the fingertip is most effective in preventing rotation, which will be described later.
また、各突条１９…，２０…は握持部８の全長

し得るようになつている。 Moreover, each of the protrusions 19..., 20... does not extend over the entire length of the grip portion 8, and both ends thereof are interrupted in the middle, as shown in FIG. In particular, it is possible to prevent the operation part 3 from moving in the longitudinal direction by hooking a finger on the discontinuous ends 21 of the protrusions 20 with a slight gap between the protrusions 16 and the protrusions 16.
さらに、握持部８を片手（左手）で握つたと

ングルノブ２２が設けられている。 Furthermore, an angle knob 22 used for bending the insertion section 2 is provided on the left side of the proximal end section 6 at a position where the thumb can reach when the grip section 8 is grasped with one hand (left hand). There is.

ことを未然に防止できる。 Therefore, when using the endoscope 1, the operator grasps the grip section 8 of the operating section 3 with his left hand. At this time,
As shown in Fig. 2, the palm of the hand touches each of the protrusions 19 of the protrusion 17, and the fingertips touch each of the protrusions 20 of the hole holder 18, so that the rotational force around the central axis of the grip is applied. It does not slip even when received, and can be held securely.
In other words, when the angle knob 22 is rotated with the thumb of that hand, a rotational force about the central grip axis is applied to the operation part 3 as a reaction, but the rotation is caused by the action of the projections 17 and 18. is suppressed and can be held in place. Therefore,
It is possible to prevent the operability from being impaired due to a change in the orientation of the operating section 3.
また、挿入部側端部７の突出し部１６と突条２
０…の途切れ端２１…との間は少しあけてあるた

握持部８の中心軸方向、つまり操作部３の長手方
向への動きを防止することができる。 In addition, the protrusion 16 of the insertion part side end 7 and the protrusion 2
There is a little space between 0... and the broken edge 21..., so if you put your little finger on this broken edge 21...,
Movement of the grip portion 8 in the central axis direction, that is, in the longitudinal direction of the operating portion 3 can be prevented.
また、手元側端部６の立上り壁９に人指し指側

間に手が位置するため、それらがストツパとなる
ため、操作部３が抜けることはない。 Furthermore, by placing the edge of the hand on the index finger side against the rising wall 9 of the proximal end portion 6, the operation portion 3 is prevented from coming off toward the insertion portion 2 side. In any case, since the user's hand is positioned between the rising wall 9 and the protruding portion 16, they act as a stopper, and the operating portion 3 will not come off.
なお、本考案は上記実施例のものに限定されな

い。さらに、突起を操作部と一体に形成すること
なく、ゴム等からなるものを貼り付けるようにし
てもよい。 Note that the present invention is not limited to the above embodiments. For example, each protrusion may be configured in a grid pattern. Furthermore, the protrusion may not be formed integrally with the operating section, but may be made of rubber or the like and may be attached thereto.

し良好な操作性を確保できる。 As explained above, the endoscope of the present invention has a grip part that can be gripped by the operator with one hand in a part of the main body of the operation part, and the outer surface of this grip part has at least the palm of the one hand that is gripping it. They are arranged long along the central axis direction of the grip part in the part that touches the fingertips, and there are more on the palm side than on the fingertip side, and the height on the palm side is lower than the height on the fingertip side to prevent slipping. It has a protrusion for use. Therefore, even if the operating section is subjected to rotational force due to operation, the gripping hand does not slip, so that the operating section can always be reliably grasped in a fixed position and good operability can be ensured.
