DETAILED DESCRIPTION

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments: Example:

[0020] like Figures 1 to 4As shown, the present invention provides a urological stone crushing and suction device, including a suction tube 1, a crushing assembly is arranged at one end of the suction tube 1, a negative pressure pump is arranged at the free end of the suction tube 1, the crushing assembly includes a plurality of clamping rods 4 arranged at one end of the suction tube 1, the free ends of the clamping rods 4 are smooth curved surfaces, impact assemblies are arranged between any two pairs of relatively arranged clamping rods 4, bearing assemblies are arranged between any other two pairs of relatively arranged clamping rods 4, and cleaning assemblies are arranged in the gaps between the remaining adjacent clamping rods 4.

[0021] like Figure 3 As shown, the impact assembly includes a support plate 5 rotatably mounted between any pair of clamping rods 4, a rotating frame 11 rotatably mounted between a group of clamping rods 4 opposite to it, a pair of sliding buttons 12 are arranged inside the rotating frame 11, and an impact hammer 15 is arranged between the two sliding buttons 12.

[0022] like Figure 3 As shown, slide grooves 14 are provided on both sides of the impact hammer 15, a limiting hole 13 is provided at one end of the slide groove 14, two slide buttons 12 are slidably clamped in the two slide grooves 14 respectively, and a control component is provided between the impact hammer 15 and the rotating frame 11.

[0023] like Figure 3 As shown, the control assembly includes a pair of clamps 19 rotatably mounted on a rotating frame 11, side grooves 7 are provided on both clamps 19, and a movable frame 17 is slidably mounted between the two side grooves 7. A control rod 10 is provided on the outer side of any rotating frame 11, and a sleeve 18 is connected to the free end of the control rod 10. The sleeve 18 is sleeved on one end of the movable frame 17, and the movable frame 17 is hinged to a connecting rod 16 provided on the impact hammer 15.

[0024] like Figure 3 As shown, a horizontal limiter is provided at the hinge between the support plate 5 and the clamping rod 4 , and a through hole is opened on the support plate 5 , and the inner diameter of the through hole is equal to the outer diameter of the impact hammer 15 .

[0025] like Figure 3 and Figure 4 As shown, the bearing assembly includes a clamping ring 28 arranged between any two pairs of clamping rods 4, and two pairs of limit buttons 27 are respectively arranged at both ends of the clamping ring 28. The inner sides of the two pairs of clamping rods 4 are provided with limit grooves 6, and the limit buttons 27 are slidably clamped in the limit grooves 6. The inner side of the clamping ring 28 is provided with a chamfer 29.

[0026] like Figure 3 and Figure 4 As shown, the cleaning assembly includes a push plate 9 slidably clamped in the gap between the clamping rods 4, a material guide slope 20 is arranged on the inner side of the top of the push plate 9, a control frame 8 is slidably clamped at the bottom of the push plate 9, and a first wedge block 24 is connected to the bottom of the control frame 8.

[0027] like Figure 3 and Figure 4As shown, the bottom end of the clamping ring 28 is connected to the fixing rod 26 through a pair of supporting rods 21, and the bottom end of the fixing rod 26 is respectively connected to a plurality of second wedge blocks 25 through a plurality of cross beams 23, and the first wedge block 24 and the second wedge block 25 are in contact through an inclined surface.

[0028] The cleaning component can cooperate with the bearing component to clean other stone fragments stuck between the remaining clamping rods 4. When stones are stuck on the outer side of the clamping ring 28 in the bearing component, the negative pressure in the suction tube 1 will gradually increase. At this time, the clamping ring 28 will drive the fixing rod 26 to move through the support rod 21 under the action of negative pressure. During the movement of the fixing rod 26, the second wedge block 25 will be driven to move through the cross beam 23. Since the first wedge block 24 and the second wedge block 25 are in contact through the inclined surface, the control frame 8 where the first wedge block 24 is located will move up under the pressure of the second wedge block 25 and slide along the bottom end of the push plate 9. When the control frame 8 moves up, it will push the push plate 9 to move up along the clamping rod 4. The guide slope 20 set on the inner side of the push plate 9 will push the stone fragments between the clamping rods 4 to the clamping ring 28, and then the stone crushing component will crush them uniformly, thereby improving the stone crushing efficiency of the stone crushing component.

[0029] like Figure 1 , Figure 2 and Figure 4 As shown, multiple groups of flushing components are arranged on the suction tube 1, and each group of flushing components includes multiple liquid guide windows 22 opened on the outside of the suction tube 1, and each liquid guide window 22 is rotatably connected to a guide plate 2, and the free end of the liquid guide window 22 is connected to an elastic pad 3, and one end of the elastic pad 3 is in contact with one end of the guide plate 2.

[0030] like Figure 1 As shown, one end of each guide plate 2 is connected to a traction rope, and all the traction ropes in each set of flushing components are clamped in a cluster block set at the free end of a suction tube 1.

[0031] The flushing component can help medical staff to clean various channels of the patient's urinary system. According to the position of the part to be flushed and the positional relationship between the suction tube 1, pull the traction rope bundle stuck in the corresponding cluster block, and the traction rope bundle will pull the guide plate 2 to rotate inward along the liquid guide window 22 opened on the outside of the suction tube 1. The inward rotation of the guide plate 2 will expose the position where the guide plate 2 was originally set at the liquid guide window 22. At this time, replace the suction pump connected to one end of the suction tube 1 with a liquid pump and pump the physiological saline for flushing into the suction tube 1.

[0032] The specific usage and function of this embodiment are as follows: The crushing assembly provided in the present invention can perform secondary crushing on the stones blocked at the suction end of the suction tube 1, thereby preventing the stones from blocking the suction tube 1 and performing secondary processing on the stones, thereby improving the suction and discharge efficiency of the stones. When the stones on the carrying assembly need to be crushed, the support plate 5 and the rotating frame 11 are driven to rotate 270 degrees from the outside to the inside, and after the rotating frame 11 is rotated to the horizontal direction, the clamping plate 19 at the top of the rotating frame 11 is driven to rotate to the vertical direction, and the impact hammer 15 will be centered along the slide groove 14 with the sliding buttons 12 provided on both sides thereof as the center. The limiting hole 13 opened at one end rotates synchronously until the impact hammer 15 rotates to align with the through hole opened on the support plate 5. Since a movable frame 17 is slidably clamped between the clamping plates 19 through the side groove 7, and since one end of the movable frame 17 is sleeved in the sleeve 18 connected to the free end of the control rod 10, the impact hammer 15 connected by the connecting rod 16 to the movable frame 17 will be pulled downward along the through hole opened in the support plate 5 during the shortening process of the control rod 10, and the impact hammer 15 can be repeatedly impacted by driving the telescopic rod to extend and retract repeatedly to complete the stone crushing.

[0033] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
