A foot-operated flushing device for ureteroscope that is convenient for precise control

Abstract

The present invention discloses a foot-operated flushing device for ureteroscopes that is convenient for precise control, including a bottom plate. A syringe is installed on the bottom plate through a mounting frame. One side of the top of the bottom plate is movably connected to a control board. A pumping and feeding assembly of the syringe is arranged at the bottom of the control board. Side plates are arranged on both sides of the control board and the side plates are installed on the bottom plate. When the moving rod extends outwards, the limiting block is used to re-lock into the internal arc-shaped gear type limiting groove, and then the sole of the foot is released to achieve a pause effect. The limiting block will still snap into the next arc-shaped gear type limiting groove recess to achieve limiting, avoiding the problem that after the control board moves downwards, the resilience of the second rotating shaft increases, but the triggering force of the limiting trigger plate remains unchanged, resulting in the resilience of the second rotating shaft being greater than the force applied by the medical staff to the limiting trigger plate when the limit is removed, causing abnormal overall stability due to local contraction.

Description

Technical Field

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

[0002] Ureteral stones are a highly prevalent disease, and with the development of ureteroscopic technology, transurethral ureteroscopic holmium laser lithotripsy is increasingly used in treatment. The advantage of a continuous electric water injection pump, or continuous flushing after suspension of the flushing fluid, is that high-flow water injection can be continuously performed during single-person surgery. The disadvantage is that it is inconvenient to adjust the water injection flow rate in real time according to surgical needs. The advantage of manual water injection with a handheld water injector is that the water injection speed can be adjusted in real time according to the actual situation during the operation. 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. In addition, if the assistants do not cooperate well, it will affect the progress of the operation. Some existing foot-operated injection devices cannot control the force of the foot when continuing to operate after stopping halfway, resulting in a rebound problem, which leads to an unstable state of the overall injection.

[0005] Pull wires are fixedly connected to the top ends of both sides of the control panel, a push plate is provided on one side of the top of the bottom plate and the two sides of the push plate are slidably connected to the two side plates respectively through two slide rails, the push plate is fixedly connected to the piston rod of the syringe, and one end of the pull wire changes direction through a guide wheel and is fixedly connected to the push plate.

[0006] Preferably, a U-shaped frame is fixedly connected to the bottom of the control panel, a trapezoidal pushing block is slidably arranged 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, the bottom of the trapezoidal pushing block passes through the U-shaped frame and an extension plate is fixedly connected to one end of the bottom of the U-shaped frame, both sides of the extension plate are elastically connected to the U-shaped frame through a limit shaft and a spring four, moving rods are arranged 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 arranged between the moving rod and the side plate.

[0007] 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.

[0008] Preferably, a limit trigger plate is movably arranged 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 arranged 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.

[0009] 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 the two ends of the second spring are respectively 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 the two ends of the metal pull wire are respectively wound around the first rotating shaft and the second rotating shaft for multiple turns.

[0010] Preferably, a turntable is movably connected to the bottom of the base plate, and circular spheres are respectively arranged 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.

[0011] 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 one, at which time the trapezoidal push block will utilize the rebound of spring four to move upward, thereby pushing the moving rod to continue to press spring three to move outward, and 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 which the limit block may hit the protrusion of the arc-shaped gear-type limit groove, but this does not affect the control plate, because the elastic force of spring four 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 limiting;

[0012] 2. By utilizing the winding connection between shaft one and shaft two and winding them multiple times, it is possible to achieve a limit after the control board rotates a certain distance. At this time, shaft two will pull the metal pull wire to pull shaft one to rotate in the opposite direction, thereby realizing a reverse force on spring one, thereby increasing the thrust of the limit trigger plate on the limit strips, prompting medical staff to continue to operate after the control board 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 board, thereby avoiding the increase in the rebound force of shaft two after the control board moves downward, but the trigger force of the limit trigger plate remains unchanged, resulting in the rebound force of shaft two 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.

[0022] Pull wires 14 are fixedly connected to the top ends 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 slidably connected to the two side plates 1 respectively through two slide rails 13, the push plate 18 is fixedly connected to the piston rod of the syringe 2, and one end of the pull wire 14 is fixedly connected to the push plate 18 by changing its direction through a guide wheel.

[0023] Specifically, a U-shaped frame 17 is fixedly connected to the bottom of the control panel 4, a trapezoidal push block 16 is slidably arranged inside the U-shaped frame 17, and one end of the trapezoidal push block 16 extends to the top of the control panel 4 through a trigger block 25, the bottom of the trapezoidal push block 16 passes through the U-shaped frame 17 and an extension plate 22 is fixedly connected to 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 arranged on both sides of the trapezoidal push block 16, and the moving rods 21 perform telescopic motion with the movement of the trapezoidal push block 16, and a limiting component is arranged between the moving rod 21 and the side panel 1.

[0024] Specifically, the limit assembly includes a limit 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 limit block 19, an arc-shaped gear-type limit groove 15 adapted to the limit block 19 is processed on the inner side of the side panel 1, a spring three 20 is arranged between the limit block 19 and the U-shaped frame 17, and the spring three 20 is sleeved on the outside of the moving rod 21.

[0025] Specifically, a limit trigger plate 5 is movably arranged inside the control board 4, the limit trigger plate 5 is movably connected to the control board 4 through a rotating shaft 6, and a limit bar 7 is arranged at the bottom of one side of the limit trigger plate 5, the limit bar 7 limits the limit trigger plate 5 from rotating in the opposite direction, a spring 8 is sleeved on the outer side of the rotating shaft 6, and the spring 8 is fixedly connected between the limit trigger plate 5 and the control board 4.

[0026] 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 outer side 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 wound around the rotating shaft 1 6 and the rotating shaft 2 9 for multiple turns.

[0027] Specifically, the bottom of the bottom plate 11 is movably connected with a turntable 12 , and four corners of the bottom 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 .

[0028] 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 and flushing are 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. When the trapezoidal push block 16 moves, the moving rod 21 retracts inwardly by 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 limit area of ​​the arc-shaped gear-type limit 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 will be pulled. 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.

[0029] like Figure 1 As shown, the occupation area of ​​the limit trigger plate 5 is small. When it is necessary to stop, the sole of the foot can be moved to one side for 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 to press 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 springs of different types. When the moving rod 21 extends outward, the limit block 19 is used to re-clamp the inside of the arc 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 bulge of the arc gear type limit groove 15, but this does not affect it, because the elastic force of the spring 4 24 and the withdrawal of the sole of the foot can achieve that when the control plate 4 hits the bulge of the arc gear type limit groove 15, it moves a unit of distance, and the limit block 19 will still be stuck in the groove of the next arc gear type limit groove 15 to achieve limitation.

[0030] By utilizing the winding connection between shaft 1 6 and shaft 2 9 and winding them multiple times, the limit can be achieved after the control board 4 rotates a certain distance. At this time, shaft 2 9 will pull the metal pull wire to pull 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 strip 7, prompting the medical staff to continue to operate after the control board 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 board 4, thereby avoiding the increase of the rebound force of shaft 2 9 after the control board 4 moves downward, but the triggering force of the limit trigger plate 5 remains unchanged, resulting in the rebound force of 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 to cause overall stability abnormality, affecting the control strength of the medical staff.

[0031] 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. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
