Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to an intelligent extracorporeal lithotripsy system for urology. Background Art

[0002] Stones refer to solid lumps formed in certain parts of the body. They are one of the common diseases in clinical practice. There are many reasons for their formation, including: metabolic abnormalities, urinary tract obstruction, infection, foreign bodies, drugs, etc. When stones are produced in the body, it will greatly affect our normal life, or cause symptoms such as pain, hematuria, and difficulty urinating. For the treatment of stones, when the stones are small, patients are generally required to drink more water and rely on urine to excrete the stones. For some larger stones, they are blocked somewhere in the body and cannot be excreted from the body through urine. At this time, some means of treatment are needed. There are many treatment methods, such as ultrasonic extracorporeal lithotripsy, drug lithotripsy, endoscopy and other methods. Among them, ultrasonic extracorporeal lithotripsy is a more common method. Ultrasonic waves are used to accurately hit the stones, crush them, and then excrete them from the body with urine.

[0003] In the prior art, the existing extracorporeal lithotripsy system has great limitations in position adjustment. When lithotripsy is required for different parts, the patient is often required to cooperate in changing position, and the patient's movement may cause the stone position to change, so the stone position needs to be re-determined, which greatly reduces the efficiency of lithotripsy. The operation steps are cumbersome and the degree of automation is low. At the same time, since ultrasonic lithotripsy should not be performed multiple times on the same part, the number of blows cannot be recorded.

The position of the frame 5 can be arbitrarily adjusted by sliding the frame 5 on the base 1, and the sliding of the intermediate block 7 in the track hole 6 of the frame 5 makes the position of the shock wave generator 12 arbitrarily adjusted on the frame 5, so that the shock wave generator 12 of the lithotripsy system can be used for lithotripsy at any position, avoiding the limitations of position adjustment in the prior art. During the entire lithotripsy process, there is no need to move the patient, which greatly improves the lithotripsy efficiency.

[0019] The slider 4 is provided with a first fixing mechanism, which includes a lower hole 17, which is provided in the slider 4, and a lower fixing block 19 is sealed and slidably connected in the lower hole 17, and two lower retaining rings 20 are fixedly connected to the inner side wall of the lower hole 17, and the lower retaining rings 20 limit the corresponding lower fixing block 19 to ensure that it can be reset to a specified position when resetting to avoid excessive sliding. The frame 5 is provided with two cavities 16, and the two opposite side walls of the frame 5 are fixedly connected with an electric push rod 14 and a liquid tank 13, and a piston 15 is sealed and slidably connected in the liquid tank 13, and the output end of the electric push rod 14 is fixedly connected to the upper surface of the piston 15, and the liquid tank 13 and the frame 5 are jointly penetrated and fixedly connected with a sixth tube 47, and the sixth tube 47 connects the liquid tank 13 with the corresponding cavity 16, and the slider 4 and the frame 5 are jointly penetrated and fixedly connected with a first tube 18, and the first tube 18 connects the lower hole 17 with the corresponding cavity 16.

[0020] A second fixing mechanism is provided in the middle block 7, and the second fixing mechanism includes an upper hole 25, in which two upper fixing blocks 29 are sealingly and slidably connected, and two upper retaining rings 30 are fixedly connected to the inner side wall of the upper hole 25. The upper retaining rings 30 limit the corresponding upper fixing blocks 29 so that the upper fixing blocks 29 can be reset to the specified position when reset. The frame 5 is penetrated and fixedly connected with two second tubes 21, the top block 8 is a hollow structure, and the two opposite side walls of the top block 8 are penetrated and fixedly connected with the third tube 22, and the corresponding second tube 21 is connected with the third tube 22 through the hose 23, and the top block 8 and the middle block 7 are penetrated and fixedly connected with the fourth tube 26, and the fourth tube 26 connects the upper hole 25 with the inside of the top block 8, and the middle block 7 and the bottom block 9 are penetrated and fixedly connected with the fifth tube 27, and the fifth tube 27 connects the upper hole 25 with the column groove 10, and the first pressure relief valve 24 is arranged in the second tube 21, and the second pressure relief valve 28 is arranged in the fifth tube 27, and the liquid tank 13, the lower hole 17, the cavity 16, and the top block 8. The upper hole 25 and the column groove 10 are filled with hydraulic oil. The electric push rod 14 starts to extend, driving the piston 15 to slide down. The piston 15 will pump the hydraulic oil in the liquid tank 13 into the cavity 16 through the sixth pipe 47, and then the hydraulic oil enters the lower hole 17 through the first pipe 18. After the hydraulic oil enters the lower hole 17, the two lower fixed blocks 19 move back to back and abut against the inner wall of the sliding groove 3. After the lower fixed block 19 abuts against the inner wall of the sliding groove 3, as the hydraulic oil continues to be pumped in, the pressure continues to increase, so that the lower fixed block 19 abuts against the inner wall of the sliding groove 3 with a certain pressure, and the position of the slider 4 is adjusted by the friction between the two. The pressure is fixed, so that the position of the frame 5 is fixed. As the pressure continues to increase, until it increases to the opening value of the first pressure relief valve 24, the first pressure relief valve 24 is opened, and the hydraulic oil will enter the hose 23 from the cavity 16 through the second pipe 21, and then enter the top block 8 through the third pipe 22, and then enter the upper hole 25 through the fourth pipe 26. After the hydraulic oil enters the upper hole 25, the two upper fixed blocks 29 move in opposite directions until the upper fixed blocks 29 are against the inner wall of the track hole 6. The pressure continues to increase, so that the upper fixed blocks 29 are against the inner wall of the track hole 6 with a certain pressure, and the position of the middle block 7 is adjusted by the friction between the two. The second pressure relief valve 28 is opened, and the hydraulic oil enters the column groove 10 through the fifth tube 27, so that the sliding column 11 slides, driving the shock wave generator 12 and the water bag 34 to gradually approach the patient's skin until they are in contact with the patient's skin. The frame 5 and the middle block 7 can be fixed by operating the electric push rod 14. After the fixation is completed, the shock wave generator 12 is automatically extended, which greatly improves the automation of the system and avoids cumbersome operations.

[0021] It should be noted that the opening value of the first pressure relief valve 24 is smaller than the opening value of the second pressure relief valve 28, thereby ensuring that after the first pressure relief valve 24 is opened, the pressure needs to be further increased to open the second pressure relief valve 28, thereby ensuring that the second pressure relief valve 28 will be opened only after the upper fixed block 29 generates a certain pressure on the inner wall of the track hole 6, thereby ensuring that the position of the intermediate block 7 is fixed, and the first pressure relief valve 24 can ensure that the lower fixed block 19 can only open after generating a certain pressure on the inner wall of the sliding groove 3, thereby ensuring a certain pressure size and generating sufficient friction to fix the position.

[0022] A control mechanism is provided at the shock wave generator 12, and the control mechanism includes two hollow side blocks 31, and the two side blocks 31 are respectively fixedly connected to the two opposite side walls of the shock wave generator 12, and the bottom wall of the side block 31 is penetrated and slidably connected with a sliding sleeve 32, one end of the sliding sleeve 32 penetrates and extends into the side block 31 and is fixedly connected with a trigger plate 36, and the other end penetrates and extends to the outside of the side block 31 and is fixedly connected to the upper surface of the movable block 33, a spring 37 is fixedly connected between the trigger plate 36 and the inner bottom wall of the side block 31, a button switch 38 is fixedly connected to the inner top wall of the side block 31, and a connecting hole 35 is provided on the bottom wall of the movable block 33, and the movable block 33 is connected to the water bag 34 is filled with pure water, which can minimize the energy loss of the shock wave when passing through the water bag 34. The water bag 34 is deformed according to the shape of the patient's skin. When the water bag 34 is completely against the patient's skin, as the sliding column 11 continues to extend, the movable block 33 slides relative to the side block 31, so that the sliding sleeve 32 slides toward the inside of the side block 31, and then drives the trigger plate 36 to slide until the trigger plate 36 contacts and presses the button switch 38. At this time, the electric push rod 14 stops moving, and the fixation is completed. After the water bag 34 is completely in contact with the patient's skin, it can stop automatically, further improving the degree of automation of the system.

[0023] A counting mechanism is provided at the sleeve 32 and the base 1. The counting mechanism includes a detection cavity 42. The detection cavity 42 is opened in the base 1. A conductive rod 43 and a coil 44 are fixedly connected between the two opposite inner walls of the detection cavity 42. The conductive rod 43 passes through the coil 44. When the current in the conductive rod 43 changes, the magnetic field generated by it will change, and the change in the magnetic field will cause an induced current to be generated in the coil 44 through which it passes. A pressure column 39 is sealed and slidably connected in the sleeve 32. A force-sensitive resistor 46 is fixedly connected to the top wall of the sleeve 32. The resistance value of the force-sensitive resistor 46 changes with the pressure it is subjected to. The pressure column 39 is offset against the force-sensitive resistor 46, the button switch 38, the electric push rod 14, the force-sensitive resistor 46, and the conductive rod 43 are connected through a PLC control circuit. The force-sensitive resistor 46 and the conductive rod 43 are connected to the power supply through a wire, and then connected to the PLC control circuit. The electric push rod 14 is connected to the power supply through a wire, and then connected to the PLC control circuit. The PLC control circuit can cut off the power to the electric push rod 14 and energize the force-sensitive resistor 46 and the conductive rod 43 after the button switch 38 is pressed. This is a prior art and will not be described in detail here. The side wall of the bottom block 9 is fixedly connected with a detection The detector 41 and the display 45 are used to detect the current change in the circuit and display the number of changes on the display 45. When a current flows, a count is performed on the display 45. This is a prior art and will not be described in detail here. The detector 41, the display 45 and the coil 44 are electrically connected through a wire. When the shock wave generator 12 emits a shock wave passing through the pure water in the water bag 34, the pressure of the pure water will change. When the internal pure water pressure changes, the pressure of the pressure column 39 on the force-sensitive resistor 46 will change, thereby causing the resistance value of the force-sensitive resistor 46 to change. Changes, and changes in the resistance of the force-sensitive resistor 46 will cause the current passing through the conductive rod 43 to change. When the current in the conductive rod 43 changes, the magnetic field generated around it will change. The change in the magnetic field will cause an induced current to be generated in the coil 44. When the detector 41 detects the induced current generated in the coil 44, it will count once and display the counting result on the display 45, thereby helping medical staff to better grasp the number of blows and avoid multiple operations that make it impossible for medical staff to accurately grasp the number of blows, resulting in excessive blows causing damage to the patient's body.

[0024] The side wall of the sleeve 32 is provided with a plurality of balancing holes 40, which connect the inside of the sleeve 32 with the outside. The balancing holes 40 are provided above the pressure column 39 (such as Fig. 9 As shown), ensure that the upper part of the pressure column 39 is in an open state, so that the sealing sliding pressure column 39 can slide freely up and down.

[0025] The side walls of the two corresponding lower fixing blocks 19 on the opposite side are glued with rubber pads, and the side walls of the two upper fixing blocks 29 on the opposite side are glued with rubber pads. The provision of the rubber pads can increase the friction force, thereby ensuring that the lower fixing block 19 and the upper fixing block 29 produce a better fixing effect through friction force and avoid slipping.

[0026] A sealing rubber ring is provided at the through-sliding connection between the shock wave generator 12 and the movable block 33. The provision of the sealing rubber ring ensures the seal between the shock wave generator 12 and the movable block 33 to avoid leakage at the through-sliding connection between the two.

[0027] In the present invention, the patient lies flat or prone on the treatment table 2 according to the location of the lithotripsy, and the medical staff determines the location of the stone through B-ultrasound and X-ray, and determines the ultrasonic impact position at the same time. After the position is determined, the frame 5 is slid. After the frame 5 is slid to the required position, the middle block 7 is slid to adjust the direction of the shock wave generator 12. After the adjustment is completed, the electric push rod 14 is turned on.

[0028] The electric push rod 14 starts to extend, driving the piston 15 to slide down. The piston 15 will pump the hydraulic oil in the liquid tank 13 into the cavity 16 through the sixth tube 47, and then the hydraulic oil will enter the lower hole 17 through the first tube 18. After the hydraulic oil enters the lower hole 17, the two lower fixed blocks 19 move away from each other and abut against the inner wall of the sliding groove 3. When the lower fixed block 19 abuts against the inner wall of the sliding groove 3, as the hydraulic oil continues to be pumped in, the pressure continues to increase, so that the lower fixed block 19 abuts against the inner wall of the sliding groove 3 with a certain pressure, and the position of the slider 4 is fixed by the friction between the two, thereby fixing the position of the frame 5.

[0029] As the pressure continues to increase, until it increases to the opening value of the first pressure relief valve 24, the first pressure relief valve 24 is opened, and the hydraulic oil will enter the hose 23 from the cavity 16 through the second tube 21, and then enter the top block 8 through the third tube 22, and then enter the upper hole 25 through the fourth tube 26. After the hydraulic oil enters the upper hole 25, the two upper fixed blocks 29 move away from each other until the upper fixed blocks 29 are against the inner wall of the track hole 6. The pressure continues to increase, so that the upper fixed blocks 29 are against the inner wall of the track hole 6 with a certain pressure, and the position of the middle block 7 is fixed by the friction between the two, so that the position of the shock wave generator 12 is fixed.

[0030] At this time, as the pressure continues to increase until it reaches the opening value of the second pressure relief valve 28, the second pressure relief valve 28 opens, and the hydraulic oil enters the column groove 10 through the fifth tube 27, so that the slide column 11 slides, driving the shock wave generator 12 and the water bag 34 to gradually approach the patient's skin until they contact the patient's skin. The water bag 34 deforms according to the shape of the patient's skin. When the water bag 34 completely contacts the patient's skin, as the slide column 11 continues to extend, the movable block 33 slides relative to the side block 31, so that the sliding sleeve 32 slides toward the inside of the side block 31, and then drives the trigger plate 36 to slide until the trigger plate 36 contacts and presses the button switch 38. At this time, the electric push rod 14 stops moving, and the fixation is completed.

[0031] The shock wave generator 12 is turned on to generate shock waves to strike the stones in the patient's body to break them up. During the striking process, when the shock wave emitted by the shock wave generator 12 passes through the pure water in the water bag 34, the pressure of the pure water will change. When the internal pure water pressure changes, the pressure of the pressure column 39 on the force-sensitive resistor 46 will change, thereby changing the resistance of the force-sensitive resistor 46. The change in the resistance of the force-sensitive resistor 46 will change the current passing through the conductive rod 43. When the current in the conductive rod 43 changes, the magnetic field generated by it around it will change. The change in the magnetic field will cause an induced current to be generated in the coil 44. When the detector 41 detects the induced current generated in the coil 44, it will count once and display the counting result on the display 45, thereby helping medical staff to better grasp the number of strikes.

[0032] After the stone crushing is completed, the electric push rod 14 is started to retract, so that the shock wave generator 12 is reset and the limit fixation of the frame 5 and the middle block 7 is released. At this time, the position of the shock wave generator 12 is continued to be adjusted, and the stone crushing can be carried out again according to the above steps.
