Reference numeral 281 denotes a male screw shaft, and the male screw shaft 281 is arranged in the vertical direction. The upper side of the male screw shaft 281 passes through the through hole 261 of the upper support case 259, and the upper end portion thereof can enter the hole 257 of the mounting block 251. The male screw shaft 281 is screwed into the screw hole 275 of the knob 271 on the way.
The lower side of the male screw shaft 281 is screwed into the screw hole 279 of the lower support case 277, and the lower end of the small diameter penetrates the through hole 280 of the lower support case 277 and protrudes from the lower side. ing. Further, a nut 287 is fastened to the male screw shaft 281, whereby the lower support case 277 is fixed to the male screw shaft 281.
Reference numeral 285 denotes a double nut, and the double nut 285 is attached to the male screw shaft 281.

Next, the usage method will be described.
By lowering or raising the lever 225, the degree of bending of the arm 209 is adjusted appropriately, and then the knob 237 is turned to adjust the position of the ball joint 121 and the pinch 161 in the front-rear direction with respect to the tip of the flexible pipe 117. .
Next, the posture of the shaft 157 of the ball 155 with respect to the main body 125 in the ball joint 121 is adjusted, and the push screw 133 is tightened to fix the posture.

Next, the above-described vertical and horizontal position adjusting means are operated. Specifically, the lock screw 262 is loosened and the tip 264 thereof is separated from the male screw shaft 281 to release the male screw shaft 281 from the locked state.
Next, the lower support case 277 is gripped with one hand, the knob 271 is turned with the other hand, and the male screw shaft 281 is moved in the vertical direction. When the lower support case 277 is raised, the lower support case 277 enters the knob 271. When the lower support case 277 contacts the ceiling surface of the knob 271, the ascending of the male screw shaft 281 is stopped there. On the other hand, when the lower surface of the double nut 285 contacts the knob 271, the descending of the male screw shaft 281 is stopped there. Following the vertical movement of the male screw shaft 281, the pinch 161 also moves up and down. Incidentally, FIG. 11 shows a state where the male screw shaft 281 is lowered to the maximum.

Next, the knob 271 is gripped with one hand, and the lower support case 277 is rotated with the other hand. Accordingly, the pinch 161 is rotated together with the ball joint 121 to adjust the horizontal direction of the pinch 161.
After these adjustments, the lock screw 262 is tightened and the tip 264 is pressed against the male screw shaft 281 to return to the locked state.
In this way, the pinch 161 can be finely adjusted not only in the vertical direction but also in the horizontal direction.

As described above, even in the second embodiment, even if there is no person who assists the operator J during the treatment, the suction tube P of the intraoral suction device can be inserted and held in the mouth, and the work efficiency is good. .
Further, since the lever 225 and the knobs 237 and 271 are close to the operator J, the lever 225 and the knobs 237 and 271 can be operated even during the treatment. Since various position adjusting means are provided at the tip of the flexible pipe 117, there is little blurring. Therefore, therapeutic safety is high.
Further, the male screw shaft 281 can be separated by loosening the lock screw 262, removing the support screw 263 from the upper support case 259, removing the support screw 263 from the hanging portion 265, and loosening the nut 287. Periodic inspection can be easily performed.

The embodiment of the present invention has been described in detail above. However, the specific configuration is not limited to this embodiment, and the present invention can be changed even if there is a design change without departing from the gist of the present invention. included.
In the first embodiment, the pinch 161 is connected to the flexible pipe 117 via the ball joint 121. However, the pinch 161 may be directly attached to the flexible pipe 117.
In the first embodiment, the flexible pipe 117 is rotatably connected to the arm 31. However, the flexible pipe 117 may be connected to the arm 31 in a state where the flexible pipe 117 does not rotate.
In the second embodiment, the ball joint vertical direction means and the pinch lateral posture adjustment means are provided below the ball joint longitudinal position adjustment means, but these may be reversed upside down. .
In the first and second embodiments, a flexible pipe is used as the support portion. However, the support portion can change the vertical distance and the lateral direction of the distal end portion relative to the base end portion by changing the angle. Any one may be used, and for example, a plurality of joints may be inserted in the middle so that the angle can be changed.

  The present invention can be used in the medical device manufacturing industry.
