When the washed gravels are in a free state, the upper limit of the impact force of the washing liquid is T1, and when the washed gravels are attached to the tissues, the impact force of the washing liquid is T2, T2> T1, that is, the gravels attached to the human tissues need a larger impact force to enable the gravels to be in the free state.

Specifically, referring to fig. 3, when the servo motor 82 drives the rotating shaft 83 to rotate, the rotating shaft 83 can drive the rotating rod 84 to rotate synchronously, so that under the guiding action of the rotating rod 84, the inner wall of the straight slot 841 can push the first sleeve rod 85 to move downwards, and meanwhile, under the guiding action of the rotating rod 84, the inner wall of the straight slot 842 can push the second sleeve rod 86 to move upwards, so that the downward movement amount of the first moving disc 2 is equal to the upward movement amount of the second moving disc 5, namely, the output quantity of flushing fluid is consistent with the back suction amount of flushing fluid, and therefore, free broken stone is collected, meanwhile, flushing fluid is not accumulated in the operation process, and the operation vision is ensured to be clear.

It should be noted that, the servo motor 82 is controlled by an external control unit, specifically, the servo motor 82 can drive the rotating shaft 83 to rotate at the speed of V1 and V2, wherein when the rotating shaft 83 rotates at the speed of V1, the pressure value in the flushing pipe 9 and the suction pipe 10 is at most T1, the flushing and suction processes are synchronous at this time, then the servo motor 82 continues to drive, and when the rotating shaft 83 rotates at the speed of V2, the pressure value in the flushing pipe 9 is T2, the flushing process is performed at this time, and the suction process is suspended.

As a preferred embodiment, the inner driving assembly 87 includes a micro electric push rod 871, a pressure sensing piece 872, a control main part and a pressure rod 873, wherein the micro electric push rod 871 is fixedly installed at the upper end of the inner wall of the chute 71, the pressure sensing piece 872 is fixed at the output end of the micro electric push rod 871, the control main part is installed in the second guide block 7, one end of the pressure rod 873 is fixed on the second sleeve rod 86, and the other end is fixed on the pressure sensing piece 872;

the input end of the control main part is electrically connected with the pressure sensing piece 872, and the output end of the control main part is electrically connected with the miniature electric push rod 871.

It should be explained that, referring to fig. 4, when it is necessary to flush the crushed stone attached to the human tissue, the driving force of the servo motor 82 is adjusted to make the rotating shaft 83 accelerate from V1 to V2, so that the pressure of the inner wall of the second 842 of the straight slot of the rotating rod 84 to the second 86 of the sleeve rod increases, that is, when the pressure sensing piece 872 monitors that the pressing force of the pressure rod 873 increases to T2, the pressure sensing piece 872 converts the pressure increasing value into an electrical signal and transmits the electrical signal to the control main part, and the control main part instructs the micro electric push rod 871 to control the hydraulic oil in the micro electric push rod 871 to flow to the side far from the hydraulic rod, so that the micro electric push rod 871 shortens.

In a preferred embodiment, a pneumatic self-locking assembly 88 is further disposed between the second sleeve rod 86 and the second moving plate 5, the pneumatic self-locking assembly 88 includes a linkage rod 881, an L-shaped rod 882, a plug 883 and a rubber column 884, through grooves are formed in the second guide block 7 and the second push rod 6, the linkage rod 881 is slidably disposed in the through grooves, the upper end of the linkage rod 881 is fixed to the second sleeve rod 86, the lower end of the linkage rod 881 is sealed and slidably penetrates through the second moving plate 5, a plurality of flow passages 51 are formed in the inner circumference of the second moving plate 5, guide grooves 52 are formed below each flow passage 51, a plurality of plugs 883 are circumferentially disposed and are respectively fixed at one ends of the L-shaped rods 882, a plurality of plugs 883 are respectively slidably disposed in the guide grooves 52, and the rubber column 884 is circumferentially disposed and slidably disposed in the plurality of flow passages 51.

It should be noted that, when the micro electric push rod 871 is not contracted, the second sleeve rod 86, the linkage rod 881 and the second guide block 7 are integrated, that is, when the second sleeve rod 86 moves, the second guide block 7 and the second push rod 6 move synchronously, so that the plug 883 is in a static state relative to the guide groove 52, that is, the air pressure in the flow channel 51 is not increased, and no friction exists between the rubber column 884 and the inner wall of the second storage barrel 12.

Specifically, referring to fig. 4 to 6, when the micro electric push rod 871 is contracted, i.e. the limit between the sleeve rod 86 and the guide block 7 is released, the sleeve rod 86 drives the linkage rod 881 to move upwards relative to the push rod 6, in this process, the L-shaped rod 882 pushes the plug 883 to move upwards, the space between the guide groove 52 and the flow channel 51 is reduced, thereby increasing the air pressure in the flow channel 51, the air pressure pushes the rubber column 884 to squeeze the inner wall of the storage cylinder 12, so that the positive pressure between the rubber column 884 and the storage cylinder 12 is increased, i.e. the friction force is increased, therefore, when the sleeve rod 86 moves upwards along with the output end of the micro electric push rod 871, a larger friction force exists between the moving disc 5 and the inner wall of the storage cylinder 12, so that the moving disc 5 and the guide block 7 remain stationary, and further the flushing fluid is suspended in this time, and the moving disc 2 moves a certain distance in this time, i.e. the flushing fluid is pressurized in the time suspension time, so that the flushing fluid is pressurized in the time suspension time, the focal position presses the inner wall of the storage cylinder 12, thereby the broken stone is washed away, and the broken stone can be kept away, and the broken tissue is washed away.

It should be noted that, in the above description, the retraction rate of the micro electric push rod 871 is the same as the moving rate of the second sleeve rod 86 driven by the rotating rod 84 in the vertical direction, specifically, when the micro electric push rod 871 is retracted, the servo motor 82 drives the rotating rod 84 to continuously rotate, the inner wall of the first straight slot 841 extrudes the first sleeve rod 85 to move downward, the micro electric push rod 871 actively drives the second sleeve rod 86 to move upward, and when the rotating rod 84 rotates, the inner wall of the second straight slot 842 contacts with the second sleeve rod 86 but does not produce the mutual extrusion, so as to avoid the driving interference between the servo motor 82 and the micro electric push rod 871.

Specifically, in implementation:

When free broken stone is washed, the state change is shown in figures 8 to 9, the washing process is synchronous with the back suction process, no accumulated washing liquid is accumulated at the focus position, and the clear surgical field is ensured;

in the process III, after the broken stone adhered to the human tissue wall is washed, the state change of the broken stone is shown in fig. 10 to 11, the rotation speed of the rotating shaft 83 driven by the servo motor 82 is reduced from V2 to below V1, namely, when the pressure sensing piece 872 monitors that the extrusion force of the pressure rod 873 on the broken stone is reduced from T2 to below T1, the pressure sensing piece 872 converts the reduction value into an electric signal again and transmits the electric signal to the control main part, the control main part controls the hydraulic oil in the miniature electric push rod 871 to flow to one side close to the hydraulic rod, so that the miniature electric push rod 871 stretches, namely, in the process, the plug 883 moves downwards firstly, the friction force between the rubber column 884 and the inner wall of the storage cylinder II 12 is reduced, and after the limit between the second moving plate 5 and the inner wall of the storage cylinder II 12 is released, the guide block II 7, the push rod II6 and the moving plate II 5 move upwards relative to the second sleeve rod 86, and finally the downward moving distance of the moving plate II 2 is the same as the upward distance of the moving plate II 5, so that the focus can completely restore the clean focus, and the clean vision can be ensured, and the clean focus can be restored.
