[0045] The liquid storage cylinder 2 is divided into multiple areas by a partition plate 502, which is convenient for storing different flushing liquids;

[0046] During use, open the top cover of the liquid storage cylinder 2 and add different flushing liquids into the liquid storage cylinder 2.

[0047] According to different patients, select different flushing liquids. Pull the sleeve 506, and the sleeve 506 slides on the fixed rod 504. The sleeve 506 drives the clamping rod 507 and the square clamping block 508 to move upward. At this time, the spring 509 is stretched until the square clamping block 508 moves out of the square clamping groove 505 and maintains the current state. Rotate the sleeve 506, and the sleeve 506 rotates on the fixed rod 504. The sleeve 506 drives the second gear 512 to rotate, the second gear 512 drives the meshing first gear 503 to rotate, the first gear 503 drives the rotating shaft 501 and the partition plate 502 to rotate, so that the flushing liquids in different areas rotate. At the same time, the rotating shaft 501 drives the pointer 510 to rotate. According to the scale disk 511, the rotated angle can be clearly observed, which is beneficial to select different flushing liquids, convenient for medical staff to use, does not require replacing the flushing liquid again, and is beneficial to the progress of the operation;

[0048] After the flushing liquid is confirmed, start the motor 308. The output shaft of the motor 308 drives the turntable 306 to rotate, the turntable 306 drives the rotating rod 305 to rotate, and the rotating rod 305 drives the piston plate 303 to reciprocate in the piston cylinder 302 through the connecting rod 304. When the piston plate 303 moves to the right, the first one-way valve on the flushing pipe 301 closes, and the second one-way valve on the drain pipe opens. At this time, the flushing liquid will enter the piston cylinder 302. When the piston plate 303 moves to the left, the first one-way valve on the flushing pipe 301 opens, and the second one-way valve on the drain pipe closes. At this time, the flushing liquid will be sprayed out through the flushing pipe 301. By continuously moving the piston plate 303, the flushing liquid can be continuously sprayed out;

[0049] Rotate the threaded rod 310, the threaded rod 310 drives the slider 307 to slide in the groove 309, and the slider 307 drives the rotating rod 305 to move, changing the moving radius, so that the sprayed flushing volume can be changed;

[0050] Rotate the lead screw 402, the lead screw 402 drives the moving block 403 to move, the moving block 403 drives the arc-shaped clamping block 406 to move, and the arc-shaped clamping block 406 drives the flushing pipe 301 to move, so that the position of the flushing pipe 301 can be adjusted;

[0051] The flushing pipe 301 can be fixed by two arc-shaped clamping blocks 406 to avoid displacement and cause discomfort to the patient. Moreover, when flushing the calculus, there is no need for manual support, saving manpower.

[0052] The usage method of a stone flushing device with controllable flushing volume includes the following steps:

[0053] S1: First, load different flushing liquids into the liquid storage cylinder 2, and then start the flushing mechanism 3;

[0054] S2: The motor 308 drives the turntable 306 to rotate. The turntable 306 drives the slider 307 to rotate. The slider 307 drives the connecting rod 304 to reciprocate through the rotating rod 305. The connecting rod 304 drives the piston plate 303. Through the reciprocating movement of the piston plate 303, the flushing liquid in the liquid storage cylinder 2 is pumped into the piston cylinder 302 and finally sprayed out through the flushing pipe 301;

[0055] S3: Pull the sleeve 506. The sleeve 506 drives the square clamping block 508 to move out of the square clamping groove 505. Keep this state and rotate the sleeve 506. The sleeve 506 drives the second gear 512 to rotate. The second gear 512 drives the first gear 503 to rotate. The first gear 503 drives the rotating shaft 501 to rotate. The rotating shaft 501 drives the partition plate 502 to rotate, thereby driving different flushing liquids to move;

[0056] S4: The lead screw 402 rotates, driving the moving block 403 to move. The moving block 403 drives the flushing pipe 301 to move through two arc-shaped clamping blocks 406. The position of the flushing pipe 301 can be adjusted. Through the relative movement of the two arc-shaped clamping blocks 406, the flushing pipe 301 can be fixed.
