Description

Technical Field

[0001] The invention belongs to the technical field of ureteroscopes, and in particular relates to a foot-operated ureteroscope flushing device that is easy to precisely control. Background Art

[0002] Ureteral stones are a common disease, and with the development of ureteroscopic technology, transurethral ureteroscopic holmium laser lithotripsy is increasingly used in treatment. Continuous electric water injection pumps, or continuous irrigation after suspension of irrigation fluid, have the advantage of continuous high-flow water injection during single-person surgery, but the disadvantage is that it is inconvenient to adjust the water injection flow in real time according to surgical needs; manual water injection with a handheld water injector has the advantage of being able to adjust the water injection speed in real time according to the actual situation during the operation, but the disadvantage is that it cannot be operated by one person, and two people are required to cooperate in the operation, which increases labor costs. If the assistants do not cooperate well, it will affect the progress of the operation. Some existing foot-operated injection devices cannot control the foot force when continuing to operate after stopping in the middle, causing rebound problems, resulting in an unstable state of the overall injection. Summary of the Invention

[0003] The object of the present invention is to provide a foot-operated ureteroscope flushing device that is easy to precisely control, so as to solve the above-mentioned problems.

[0005] Preferably, the bottom of the control panel is fixedly connected to a U-shaped frame, and a trapezoidal pushing block is slidingly provided inside the U-shaped frame, and one end of the trapezoidal pushing block extends to the top of the control panel through a trigger block, and the bottom of the trapezoidal pushing block passes through the U-shaped frame and is fixedly connected to an extension plate at one end placed at the bottom of the U-shaped frame, and both sides of the extension plate are elastically connected to the U-shaped frame through a limit shaft and a spring four, and moving rods are provided on both sides of the trapezoidal pushing block and the moving rods perform telescopic motion with the movement of the trapezoidal pushing block, and a limiting assembly is provided between the moving rod and the side plate.

[0006] Preferably, the limit assembly includes a limit block, one end of the moving rod extends to the outside of the U-shaped frame and is fixedly connected to the limit block, the inner side of the side plate is processed with an arc-shaped gear-type limit groove that is compatible with the limit block, and a spring three is arranged between the limit block and the U-shaped frame, and the spring three is sleeved on the outside of the moving rod.

[0007] Preferably, a limit trigger plate is movably provided inside the control panel, the limit trigger plate is movably connected to the control panel through a rotating shaft 1, and a limit bar is provided at the bottom of one side of the limit trigger plate, the limit bar limits the limit trigger plate from rotating in the opposite direction, a spring 1 is sleeved on the outer side of the rotating shaft 1, and the spring 1 is fixedly connected between the limit trigger plate and the control panel.

[0008] Preferably, the control panel is movably connected to the boss on the side panel via the second rotating shaft, a second spring is sleeved on the outer side of the second rotating shaft and both ends of the second spring are fixedly connected between the control panel and the boss on the side panel, a metal pull wire is wound around the first rotating shaft and the second rotating shaft, and both ends of the metal pull wire are wound around the first rotating shaft and the second rotating shaft for multiple turns.

[0009] Preferably, a turntable is movably connected to the bottom of the base plate, and circular spheres are respectively provided at the four corners of the base plate, and the lowest points of the circular spheres are in the same horizontal plane as the bottom surface of the turntable.

[0010] The technical effects and advantages of the present invention are as follows: 1. By moving the sole of the foot to one side for a certain distance, the limit trigger plate is reset by utilizing the rebound force of spring 1. At this time, the trapezoidal pushing block will utilize the rebound of spring 4 to move upward, thereby pushing the moving rod to continue pressing spring 3 to move outward. When the moving rod extends outward, the limit block is used to re-engage the inside of the arc-shaped gear-type limit groove, and then the sole of the foot is released to achieve a pause effect. During this period, the limit block may hit the protrusion of the arc-shaped gear-type limit groove, but this has no effect, because the elastic force of spring 4 and the withdrawal of the sole of the foot can achieve that when the control plate hits the protrusion of the arc-shaped gear-type limit groove, the limit block will still be stuck in the groove of the next arc-shaped gear-type limit groove to achieve limitation. 2. By utilizing the winding connection between the rotating shaft 1 and the rotating shaft 2 and winding it multiple times, it is possible to achieve a limit after the control plate rotates a certain distance. At this time, the rotating shaft 2 will pull the metal pull wire to pull the rotating shaft 1 to rotate in the opposite direction, realizing a reverse force on the spring 1, thereby increasing the thrust of the limit trigger plate on the limit bar, prompting the medical staff to continue to operate after the control plate rotates a certain distance. The downward pressure resistance of the limit trigger plate will be increased according to the influence of the first position of the control plate, thereby avoiding the increase in the rebound force of the rotating shaft 2 after the control plate moves downward, but the triggering force of the limit trigger plate remains unchanged, resulting in the rebound force of the rotating shaft 2 being greater than the force applied by the medical staff on the limit trigger plate when the limit is removed, causing local contraction and abnormal overall stability.

[0013] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0014] The present invention provides a precisely controlled foot-operated ureteroscope flushing device, as shown in the figure, comprising a base plate 11, a syringe 2 mounted on the base plate 11 via a mounting bracket 3, a control panel 4 movably connected to one side of the top of the base plate 11, a pumping assembly for the syringe 2 disposed at the bottom of the control panel 4, and side panels 1 disposed on both sides of the control panel 4 and mounted on the base plate 11; A pull wire 14 is fixedly connected to the top of both sides of the control panel 4, a push plate 18 is provided on one side of the top of the bottom plate 11, and the two sides of the push plate 18 are slidingly connected to the two side plates 1 through two slide rails 13 respectively. The push plate 18 is fixedly connected to the piston rod of the syringe 2, and one end of the pull wire 14 changes direction through a guide wheel and is fixedly connected to the push plate 18.

[0015] Specifically, a U-shaped frame 17 is fixedly connected to the bottom of the control panel 4, and a trapezoidal pushing block 16 is slidingly provided inside the U-shaped frame 17, and one end of the trapezoidal pushing block 16 extends to the top of the control panel 4 through the trigger block 25. The bottom of the trapezoidal pushing block 16 passes through the U-shaped frame 17 and is fixedly connected to an extension plate 22 at one end of the bottom of the U-shaped frame 17. Both sides of the extension plate 22 are elastically connected to the U-shaped frame 17 through a limit shaft 23 and a spring four 24. Moving rods 21 are provided on both sides of the trapezoidal pushing block 16, and the moving rods 21 perform telescopic motion with the movement of the trapezoidal pushing block 16. A limiting component is provided between the moving rod 21 and the side panel 1.

[0016] Specifically, the limiting assembly includes a limiting block 19, one end of the moving rod 21 extends to the outside of the U-shaped frame 17 and is fixedly connected to the limiting block 19, and an arc-shaped gear-type limiting groove 15 adapted to the limiting block 19 is processed on the inner side of the side panel 1. A spring three 20 is arranged between the limiting block 19 and the U-shaped frame 17, and the spring three 20 is sleeved on the outside of the moving rod 21.

[0017] Specifically, a limit trigger plate 5 is movably provided inside the control board 4. The limit trigger plate 5 is movably connected to the control board 4 through a rotating shaft 1 6, and a limit bar 7 is provided at the bottom of one side of the limit trigger plate 5. The limit bar 7 limits the reverse rotation of the limit trigger plate 5. A spring 1 8 is sleeved on the outside of the rotating shaft 1 6 and the spring 1 8 is fixedly connected between the limit trigger plate 5 and the control board 4.

[0018] Specifically, the control panel 4 is movably connected to the boss on the side panel 1 through the rotating shaft 2 9. A spring 2 10 is sleeved on the outside of the rotating shaft 2 9, and the two ends of the spring 2 10 are respectively fixedly connected between the control panel 4 and the boss on the side panel 1. A metal pull wire is wound around the rotating shaft 1 6 and the rotating shaft 2 9, and the two ends of the metal pull wire are respectively wrapped around the rotating shaft 1 6 and the rotating shaft 2 9 for multiple turns.

[0019] Specifically, the bottom of the base plate 11 is movably connected to the turntable 12 , and four corners of the base plate 11 are respectively provided with round spheres, and the lowest points of the round spheres are in the same horizontal plane as the bottom surface of the turntable 12 .

[0020] Working principle: When using the present invention, the device is placed on the ground and fixed, and then the medical staff can freely adjust the appropriate angle according to the setting of the turntable 12. When injection flushing is needed, the medical staff first steps on the limit trigger plate 5, and presses the trigger block 25 by rotating the limit trigger plate 5. The trigger block 25 is used to push the trapezoidal push block 16 and the extension plate 22 to move. While the trapezoidal push block 16 moves, the moving rod 21 retracts inwardly due to the rebound force of the spring three 20. When the moving rod 21 retracts inwardly, it will drive the limit block 19 to withdraw from the limiting area of ​​the arc-shaped gear-type limiting groove 15, thereby releasing the rotation limit of the control plate 4. At this time, the medical staff continues to step down to press the control plate 4 to rotate and move downward. When the control plate 4 rotates and moves downward, the pull wire 14 is pulled, and the two pull wires 14 are used to pull the push plate 18 to drive the piston rod of the syringe 2 to move inward, thereby achieving the purpose of injection; like Figure 1 As shown, the limit trigger plate 5 occupies a small area. When it is necessary to stop, the sole of the foot can be moved to the side a certain distance, and the limit trigger plate 5 is reset by the rebound force of the spring 1 8. At this time, the trapezoidal pushing block 16 will move upward by the rebound of the spring 4 24, thereby pushing the moving rod 21 to continue pressing the spring 3 20 to move outward. The elastic force of the spring 4 24 here is much greater than the elastic force of the spring 3 20. This effect can be achieved by selecting different types of springs. When the moving rod 21 extends outward, the limit block 19 is used to re-engage the inside of the arc-shaped gear-type limit groove 15, and then the sole of the foot is released to achieve a pause effect. During this period, the limit block 19 may hit the convex part of the arc-shaped gear-type limit groove 15, but this does not affect the control panel 4 because the elastic force of the spring 4 24 and the withdrawal of the sole of the foot can achieve that when the control panel 4 hits the convex part of the arc-shaped gear-type limit groove 15, the limit block 19 will still be locked in the groove of the next arc-shaped gear-type limit groove 15 to achieve the limit. By utilizing the winding connection between rotating shaft 1 6 and rotating shaft 2 9 and winding them multiple times, it is possible to achieve the limit after the control plate 4 rotates a certain distance. At this time, rotating shaft 2 9 will pull the metal pull wire to pull rotating shaft 1 6 to rotate in the opposite direction, thereby realizing the reverse force on spring 1 8, thereby increasing the thrust between the limit trigger plate 5 and the limit bar 7, prompting the medical staff to continue to operate after the control plate 4 rotates a certain distance. The downward pressure resistance of the limit trigger plate 5 will be increased according to the influence of the first position of the control plate 4, thereby avoiding the increase in the rebound force of rotating shaft 2 9 after the control plate 4 moves downward, but the triggering force of the limit trigger plate 5 remains unchanged, resulting in the rebound force of rotating shaft 2 9 being greater than the force applied by the medical staff on the limit trigger plate 5 when the limit is removed, causing local contraction and abnormal overall stability, affecting the control force of the medical staff.

[0021] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
