[0020] refer to Figures 1 to 11 A urological stone flushing device comprises an outer box body 1, a movable disk 2, a push rod 3, a guide block 4, a movable disk 5, a push rod 6, a guide block 7, a drive assembly 8, a flushing tube 9 and a suction tube 10; the outer box body 1 is symmetrically provided with a storage cylinder 11 and a storage cylinder 2 12 from the upper end to the inside, the movable disk 2 is sealingly and slidably arranged in the storage cylinder 11, the push rod 3 is fixed to the center of the upper end surface of the movable disk 2, the guide block 4 is fixed to the push rod 6, the guide block 4 is fixed to the push rod 6, the guide block 4 is fixed to the push rod 6, the guide block 4 is fixed to the push rod 6, the guide block 4 is fixed to the push rod 6, the guide block 4 is fixed to the guide block 4, the flushing tube 9 and the suction tube 10; the outer box body 1 is symmetrically provided with a storage cylinder 11 and a storage cylinder 2 12 from the upper end to the inside, the movable disk 2 is sealingly and slidably arranged in the storage cylinder 11, the push rod 3 is fixed to the center of the upper end surface of the movable disk 2 ... guide block 4, the flushing tube 9 and the suction tube 10; the outer box At the upper end of rod 13, the movable disk 25 is sealingly and slidably arranged in the storage cylinder 2 12, the push rod 26 is fixed to the center of the upper end surface of the movable disk 25, the guide block 27 is fixed to the upper end of the push rod 26, the driving assembly 8 is arranged between the guide block 14 and the guide block 27, the flushing pipe 9 is sealingly connected and arranged at the lower end of the storage cylinder 11, the back-suction pipe 10 is sealingly connected and arranged at the lower end of the storage cylinder 2 12, and pressure valves 101 are arranged in both the flushing pipe 9 and the back-suction pipe 10.

[0021] It should be explained that when the push rod 13 pushes the movable disk 12 downward, the positive pressure in the storage cylinder 11 will open the pressure valve 101 on this side, and the flushing liquid in the storage cylinder 11 will enter the lesion position through the flushing tube 9 to flush the gravel, and when the push rod 26 pulls the movable disk 25 upward, the negative pressure in the storage cylinder 2 12 will open the pressure valve 101 on this side, and the flushing liquid after flushing will enter the storage cylinder 2 12 through the back suction tube 10.

[0022] As a preferred embodiment, the driving assembly 8 includes a fixed frame 81, a servo motor 82, a rotating shaft 83, a rotating rod 84, a sleeve rod 1 85, a sleeve rod 2 86 and an internal drive assembly 87; the fixed frame 81 is fixed to the upper end surface of the outer box body 1, the servo motor 82 is fixed to the fixed frame 81, the rotating shaft 83 is fixed to the output end of the servo motor 82, and rotates through the fixed frame 81, the rotating rod 84 is fixed to the rotating shaft 83, and a straight slot 1 841 and a straight slot 2 842 are respectively opened on both sides of the rotating rod 84, the sleeve rod 1 85 is fixed to one side of the guide block 1 4, and is slidably arranged in the straight slot 1 841, the guide block 2 7 is opened with a slide groove 71 along the end surface inward, the sleeve rod 2 86 is arranged in the slide groove 71, and is slidably arranged in the straight slot 2 842, and the internal drive assembly 87 is arranged in the slide groove 71.

[0023] It should be noted that when the flushed gravel is in a free state, the upper limit of the impact force of the required flushing fluid is T1. When the flushed gravel is attached to the tissue, the required impact force of the flushing fluid is T2, T2>T1. In other words, the gravel attached to the human tissue requires a larger impact force to make the gravel in a free state.

[0024] For details, please refer to Figure 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. Therefore, under the guidance of the rotating rod 84, the inner wall of the straight slot 841 can push the sleeve rod 85 to move downward. At the same time, under the guidance of the rotating rod 84, the inner wall of the straight slot 842 can push the sleeve rod 86 to move upward. Therefore, the downward movement of the moving disk 1 2 is equal to the upward movement of the moving disk 2 5, that is, the output amount of the flushing liquid is consistent with the back-absorption amount of the flushing liquid, so that while collecting the free gravel, the flushing liquid will not accumulate during the operation, ensuring a clear surgical field of view.

[0025] 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 rates of V1 and V2. When the rotating shaft 83 rotates at a rate of V1, the maximum pressure value in the flushing pipe 9 and the back-suction pipe 10 is T1. At this time, the flushing and back-suction processes are synchronized. Subsequently, the servo motor 82 continues to drive and drives the rotating shaft 83 to rotate at a rate of V2. The pressure value in the flushing pipe 9 is T2. At this time, the flushing process is carried out and the back-suction process is paused.

[0026] As a preferred embodiment, the inner drive assembly 87 includes a micro electric push rod 871, a pressure sensing sheet 872, a control main component and a pressure rod 873; the micro electric push rod 871 is fixedly mounted on the upper end of the inner wall of the slide slot 71, the pressure sensing sheet 872 is fixed on the output end of the micro electric push rod 871, the control main component is mounted in the guide block 7, one end of the pressure rod 873 is fixed on the sleeve rod 86, and the other end is fixed on the pressure sensing sheet 872; The input end of the control main component is electrically connected to the pressure sensing sheet 872 , and the output end of the control main component is electrically connected to the micro electric push rod 871 .

[0027] For explanation, see Figure 4 When it is necessary to flush the gravel attached to the human tissue, the driving force of the servo motor 82 is adjusted to speed up the rotating shaft 83 from V1 to V2, thereby increasing the pressure of the inner wall of the straight slot 842 of the rotating rod 84 on the sleeve rod 86, that is, when the pressure sensing sheet 872 monitors that the squeezing force of the pressure rod 873 on it rises to T2, the pressure sensing sheet 872 will convert this pressure increase value into an electrical signal and transmit it to the control main component. The control main component will issue an instruction to the micro electric push rod 871 to control the hydraulic oil in the micro electric push rod 871 to flow to the side away from the hydraulic rod, so that the micro electric push rod 871 will shorten.

[0028] As a preferred embodiment, a pneumatic self-locking component 88 is also provided between the sleeve rod 2 86 and the movable disk 2 5, and the pneumatic self-locking component 88 includes a linkage rod 881, an L-shaped rod 882, a plug 883 and a rubber column 884; a through groove is provided in the guide block 2 7 and is connected to the push rod 2 6, and the linkage rod 881 is slidably arranged in the through groove, and the upper end of the linkage rod 881 is fixed to the sleeve rod 2 86, and the lower end of the linkage rod 881 is sealed and slides through the movable disk 2 5, and a plurality of flow channels 51 are provided on the inner circumference of the movable disk 2 5, and a guide groove 52 is provided under each flow channel 51, a plurality of plugs 883 are arranged on the circumference, and are respectively fixed at one end of the plurality of L-shaped rods 882 away from each other, and the plurality of plugs 883 are respectively slidably arranged in the plurality of guide grooves 52, and a plurality of rubber columns 884 are arranged on the circumference, and are respectively sealed and slidably arranged in the plurality of flow channels 51.

[0029] It needs to be explained that when the micro electric push rod 871 is not retracted, the sleeve rod 86 and the linkage rod 881 are integrated with the guide block 7, that is, when the sleeve rod 86 moves, the guide block 7 and the push rod 6 will move synchronously, so that the plug 883 is in a stationary state relative to the guide groove 52, that is, the air pressure in the flow channel 51 will not increase, and there is no friction between the rubber column 884 and the inner wall of the storage tube 12.

[0030] For details, please refer to Figures 4 to 6 When the micro electric push rod 871 contracts, that is, the limit between the sleeve rod 86 and the guide block 7 is released, the sleeve rod 86 will drive the linkage rod 881 to move upward relative to the push rod 6. During this process, the L-shaped rod 882 will push the plug 883 upward, and the space in the guide groove 52 and the flow channel 51 will be reduced, so that the air pressure in the flow channel 51 will increase. This air pressure will push 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 increases, that is, the friction force increases. Therefore, when the sleeve rod 86 moves upward with the output end of the micro electric push rod 871, In the process, there is a large friction force between the movable disk 2 5 and the inner wall of the storage cylinder 2 12, so that the movable disk 2 5 and the guide block 2 7 will remain stationary, and then the back-absorption of the flushing liquid will be suspended during this period of time, and the movable disk 1 2 will move down a certain distance during this period of time, that is, pressurized flushing is performed during the time of suspension of the back-absorption of the flushing liquid. Therefore, during this period of time, the flushing liquid at the lesion can flush the gravel attached to the tissue into a free state, and at the same time, a certain amount of flushing liquid can be retained at the lesion. The retained flushing liquid can have a certain buffering effect on the flushed gravel, thereby avoiding the impact damage of the flushed gravel to human tissue.

[0031] It should be noted that, in the above, the retraction rate of the micro electric push rod 871 is the same as the movement rate of the sleeve rod 86 in the vertical direction driven by the rotating rod 84. Specifically, when the micro electric push rod 871 contracts, the servo motor 82 drives the rotating rod 84 to rotate continuously, and the inner wall of the straight slot 841 squeezes the sleeve rod 85 to move downward. The micro electric push rod 871 will actively drive the sleeve rod 86 to move upward. When the rotating rod 84 rotates, the inner wall of the straight slot 842 and the sleeve rod 86 are in contact but no mutual squeezing occurs, thereby avoiding driving interference between the servo motor 82 and the micro electric push rod 871.

[0032] Specifically, during implementation: Process I: When the free gravel is washed, its state changes refer to Figures 8 to 9 The flushing process is synchronized with the aspiration process, and there is no accumulated flushing fluid at the lesion site, ensuring a clear surgical field of view; Process II: When the gravel attached to the human tissue wall is washed, its state changes refer to Figures 9 and 10During this process, the sleeve rod 86 will drive the linkage rod 881 to move upward relative to the push rod 6, and the L-shaped rod 882 will push the plug 883 upward, and the air pressure in the flow channel 51 will increase. This air pressure will push the rubber column 884 to squeeze the inner wall of the storage tube 12, thereby increasing the friction between the rubber column 884 and the storage tube 12. Therefore, when the sleeve rod 86 moves upward with the output end of the micro-electric push rod 871, there is a large friction between the moving disk 5 and the inner wall of the storage tube 12, so that the moving disk 5 and the guide block 7 will remain stationary, and then the back suction of the flushing liquid will be suspended during this period of time, and the moving disk 12 will move down a certain distance during this period of time, that is, pressurized flushing is performed during the time when the back suction of the flushing liquid is suspended. Therefore, during this period of time, the flushing liquid at the lesion can flush the gravel attached to the tissue into a free state, and at the same time, a certain amount of flushing liquid can be retained at the lesion. The retained flushing liquid can have a certain buffering effect on the flushed gravel, thereby preventing the flushed gravel from causing impact damage to human tissue; Process III: After the gravel attached to the human tissue wall is flushed, its state changes can be seen in Figure 10 to Figure 11 , the servo motor 82 drives the rotation speed of the rotating shaft 83 to decrease from V2 to below V1, that is, when the pressure sensing sheet 872 monitors the squeezing force of the pressure rod 873 on it from T2 to below T1, thereafter, the pressure sensing sheet 872 will again convert this pressure reduction value into an electrical signal and transmit it to the control main component, and the control main component will control the hydraulic oil in the micro electric push rod 871 to flow to the side close to the hydraulic rod, so that the micro electric push rod 871 extends, that is, in this process, the plug 883 will move down first, and the friction between the rubber column 884 and the inner wall of the storage cylinder 12 will decrease. When the limit between the moving disk 2 5 and the inner wall of the storage cylinder 12 is released, the guide block 2 7, the push rod 2 6 and the moving disk 2 5 will move up relative to the sleeve rod 2 86, and finally move to the initial relative position with the sleeve rod 2 86, and then the downward movement distance of the moving disk 1 2 is the same as the upward movement distance of the moving disk 2 5. Therefore, the flushing fluid remaining at the lesion can be completely sucked back, so that the lesion position is restored to a dry state, ensuring a clear surgical field of view.

[0033] As a preferred embodiment, a feed end 21 is provided on the moving disk 1 2. That is to say, initially, the storage cylinder 11 is filled with flushing liquid through the feed end 21, and then it is closed to form a sealed state in the storage cylinder 11.

[0034] As a preferred embodiment, a communication channel 13 is opened between the lower ends of the storage cylinder 1 11 and the storage cylinder 2 12 , and a micro suction pump 14 is arranged in the communication channel 13 . The micro suction pump 14 is controlled by an external control unit.

[0035] It should be explained that after a flushing is completed, the flushing liquid sucked into the storage cylinder 2 12 can be pumped into the storage cylinder 1 11 by externally controlling the micro suction pump 14, so that the flushing liquid can be reused to avoid wasting resources.

[0036] As a preferred embodiment, the return suction pipe 10 is also provided with a U-shaped tube 102, a block 103, a filter screen 104 and a collection chamber 105; the two ends of the U-shaped tube 102 are respectively connected and arranged on the return suction pipe 10, the block 103 is fixed in the return suction pipe 10 between the two ends of the U-shaped tube 102, the filter screen 104 is obliquely fixed in the U-shaped tube 102, and the collection chamber 105 is connected and arranged on the U-shaped tube 102, and is located at the front end side of the filter screen 104.

[0037] See also Figure 6 The flushing liquid and the gravel are blocked by the block 103 and enter the U-shaped tube 102. The gravel is filtered by the filter screen 104 and enters the collection chamber 105, so that the flushing liquid can be reused.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
