Description

Technical Field

[0001] The present invention relates to the technical field of stone aspiration, and more specifically, to a urological stone crushing and aspiration device. Background Art

[0002] Urinary system stones refer to stones occurring in the urinary system such as the kidney, ureter, bladder, etc., which are common urinary system diseases, usually caused by metabolic abnormalities (urine pH, hypercalcemia, urinary calcium, etc.), urinary tract obstruction or infection, and certain drug factors. They are divided into upper urinary tract stones and lower urinary tract stones according to the location of the stones, with kidney and ureteral stones being the most common.

[0003] However, during the process of aspirating stone fragments with existing urological stone crushing and aspiration devices, the stone particles may block the aspiration pipeline, affecting the normal operation of the device, and usually, larger stones need to be processed twice for the patient to excrete, thereby reducing the efficiency of stone excretion. Summary of the Invention

[0004] The present invention provides a urological stone crushing and aspiration device to solve the problem that during the process of aspirating stone fragments with existing urological stone crushing and aspiration devices, the stone particles may block the aspiration pipeline, affecting the normal operation of the device, and thus reducing the stone excretion efficiency.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A urological stone crushing and aspiration device includes an aspiration tube. One end of the aspiration tube is provided with a crushing assembly, and the free end of the aspiration tube is connected with a negative pressure pump. The crushing assembly includes a plurality of clamping rods arranged at one end of the aspiration tube. The free end of the clamping rod is a smooth curved surface. An impact assembly is arranged between any two pairs of oppositely arranged clamping rods, and a bearing assembly is arranged between any other two pairs of oppositely arranged clamping rods. A cleaning assembly is arranged in the gap between the remaining adjacent clamping rods.

[0007] Preferably, the impact assembly includes a support plate rotatably clamped between any pair of the clamping rods, and a rotating frame is rotatably clamped between a set of the clamping rods opposite in position. A pair of sliding buttons is arranged inside the rotating frame, and an impact hammer is arranged between the two sliding buttons.

[0008] Preferably, sliding grooves are opened on both sides of the impact hammer, and a limiting hole is opened at one end of the sliding groove. The two sliding buttons are respectively slidably clamped in the two sliding grooves, and a control assembly is arranged between the impact hammer and the rotating frame.

[0009] Preferably, the control component includes a pair of clamping plates rotatably clamped on the turntable. Side grooves are formed in both of the two clamping plates. A moving frame is slidably clamped between the two side grooves. A control rod is arranged outside any one of the turntables. The free end of the control rod is connected with a sleeve. The sleeve is sleeved on one end of the moving frame. The moving frame is hinged to a connecting rod arranged on the impact hammer.

[0010] Preferably, a horizontal limit is arranged at the hinge joint of the support plate and the clamping rod. A through hole is formed in the support plate. The inner diameter of the through hole is equal to the outer diameter of the impact hammer.

[0011] Preferably, the bearing component includes a clamping ring arranged between any two pairs of the clamping rods. Two pairs of limiting buttons are respectively arranged at both ends of the clamping ring. Limiting grooves are formed in the inner sides of both pairs of the clamping rods. The limiting buttons are slidably clamped in the limiting grooves. A chamfer is formed in the inner side of the clamping ring.

[0012] Preferably, the cleaning component includes a push plate slidably clamped between the clamping rods. A material guiding slope is arranged on the inner side of the top end of the push plate. A control frame is slidably clamped at the bottom end of the push plate. A first wedge block is connected to the bottom end of the control frame.

[0013] Preferably, the bottom end of the clamping ring is connected with a fixing rod through a pair of support rods. The bottom end of the fixing rod is respectively connected with a plurality of second wedge blocks through a plurality of cross beams. The first wedge block is in contact with the second wedge block through an inclined surface.

[0014] Preferably, multiple groups of flushing components are arranged on the suction pipe. Each group of flushing components includes a plurality of liquid guiding windows formed on the outer side of the suction pipe. A guide plate is rotatably connected in each liquid guiding window. An elastic pad is connected to the free end of the liquid guiding window. One end of the elastic pad is in contact with one end of the guide plate.

[0015] Preferably, a traction rope is connected to one end of each guide plate. All the traction ropes in each group of flushing components are clamped in a bundling block arranged at the free end of one suction pipe.

[0016] The principle and beneficial effects of this technical solution:

[0017] (1) The crushing assembly provided in the present invention can perform secondary crushing on the stones blocked at the suction end of the suction tube, thereby preventing the stones from blocking the suction tube and performing secondary treatment on the stones, thereby improving the suction and discharge efficiency of the stones. When the stones on the supporting assembly need to be crushed, the support plate and the rotating frame are driven to rotate 270 degrees from the outside to the inside, and after the rotating frame is rotated to the horizontal direction, the clamping plate fixed at the top of the rotating frame is driven to rotate to the vertical direction. The impact hammer will rotate synchronously along the limit hole opened at one end of the slide groove with the sliding buttons set on both sides of the hammer as the center until the impact hammer rotates to align with the through hole opened on the support plate. The telescopic rod is driven to be repeatedly extended and retracted to make the impact hammer repeatedly impact the stone until the stone is crushed.

[0018] (2) The cleaning assembly provided in the present invention can cooperate with the supporting assembly to clean other stone fragments stuck between the remaining clamping rods. When stones are stuck on the outer side of the clamping ring in the supporting assembly, the negative pressure in the suction tube will gradually increase, and the guide slope provided on the inner side of the push plate will push the stone fragments between the clamping rods onto the clamping ring, and then the stone crushing assembly will crush them uniformly, thereby improving the stone crushing efficiency of the stone crushing assembly.

[0019] (3) The flushing assembly provided in the present invention 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, the traction rope bundle stuck in the corresponding cluster block is pulled, and the traction rope bundle will pull the guide plate to rotate inward along the liquid guide window opened on the outside of the suction tube. The inward rotation of the guide plate will expose the position of the guide plate originally set in the liquid guide window. At this time, the suction pump connected to one end of the suction tube is replaced with a liquid pump and the physiological saline for flushing is pumped into the suction tube.

Detailed implementation manners

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and implementation manners:

[0026] Embodiment:

[0027] As Figures 1 to 4 shown, the present invention provides a urological lithotripsy and suction device, including a suction tube 1. One end of the suction tube 1 is provided with a crushing assembly, and the free end of the suction tube 1 is connected with a negative pressure pump. The crushing assembly includes a plurality of clamping rods 4 arranged at one end of the suction tube 1. The free end of the clamping rod 4 is a smooth curved surface. An impact assembly is arranged between any two pairs of oppositely arranged clamping rods 4, and a bearing assembly is arranged between any other two pairs of oppositely arranged clamping rods 4. A cleaning assembly is arranged in the gap between the remaining adjacent clamping rods 4.

[0028] As Figure 3 shown, the impact assembly includes a support plate 5 rotatably clamped between any pair of clamping rods 4, and a rotating frame 11 is rotatably clamped between a set of clamping rods 4 opposite in position. 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.

[0029] As Figure 3 shown, sliding grooves 14 are opened on both sides of the impact hammer 15, and limit holes 13 are opened at one end of the sliding grooves 14. The two sliding buttons 12 are respectively slidably clamped in the two sliding grooves 14, and a control assembly is arranged between the impact hammer 15 and the rotating frame 11.

[0030] As Figure 3 shown, the control assembly includes a pair of clamping plates 19 rotatably clamped on the rotating frame 11. Side grooves 7 are opened on both clamping plates 19, and a moving frame 17 is slidably clamped between the two side grooves 7. A control rod 10 is arranged outside any rotating frame 11. The free end of the control rod 10 is connected with a sleeve 18. The sleeve 18 is sleeved on one end of the moving frame 17, and the moving frame 17 is hinged with a connecting rod 16 arranged on the impact hammer 15.

[0031] As Figure 3 shown, a horizontal limit is provided at the hinge joint between the support plate 5 and the clamping rod 4. 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.

[0032] As Figure 3 and Figure 4 shown, the bearing assembly includes a clamping ring 28 arranged between any two pairs of clamping rods 4. Two pairs of limiting buttons 27 are respectively arranged at both ends of the clamping ring 28. Limiting grooves 6 are formed on the inner sides of both pairs of clamping rods 4. The limiting buttons 27 are slidably clamped in the limiting grooves 6, and a chamfer 29 is formed on the inner side of the clamping ring 28.

[0033] As Figure 3 and Figure 4 shown, the cleaning assembly includes a push plate 9 slidably clamped in the gap between the clamping rods 4. A material guiding slope 20 is arranged on the inner side of the top end of the push plate 9. A control frame 8 is slidably clamped at the bottom end of the push plate 9, and a first wedge-shaped block 24 is connected to the bottom end of the control frame 8.

[0034] As Figure 3 and Figure 4 shown, a fixing rod 26 is connected to the bottom end of the clamping ring 28 through a pair of support rods 21. The bottom ends of the fixing rods 26 are respectively connected to a plurality of second wedge-shaped blocks 25 through a plurality of cross beams 23. The first wedge-shaped block 24 and the second wedge-shaped block 25 are in contact through an inclined surface.

[0035] The cleaning assembly can cooperate with the bearing assembly to clean other stone fragments clamped between the remaining clamping rods 4. When a stone is clamped on the outer side of the clamping ring 28 in the bearing assembly, 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 the negative pressure. During the movement of the fixing rod 26, the second wedge-shaped block 25 will be driven to move through the cross beam 23. Since the first wedge-shaped block 24 and the second wedge-shaped block 25 are in contact through an inclined surface, the control frame 8 where the first wedge-shaped block 24 is located will move upward and slide along the bottom end of the push plate 9 under the extrusion of the second wedge-shaped block 25. While the control frame 8 moves upward, it will push the push plate 9 to move upward along the clamping rod 4. The material guiding slope 20 arranged on the inner side of the push plate 9 will push the stone fragments between the clamping rods 4 onto the clamping ring 28, and then they will be uniformly broken by the stone crushing assembly, thereby improving the stone crushing efficiency of the stone crushing assembly.

[0036] As Figure 1 、 Figure 2 and Figure 4 shown, multiple groups of flushing assemblies are arranged on the suction tube 1. Each group of flushing assemblies includes a plurality of liquid guiding windows 22 formed on the outer side of the suction tube 1. A guide plate 2 is rotatably connected in each liquid guiding window 22. An elastic pad 3 is connected to the free end of the liquid guiding window 22. One end of the elastic pad 3 is in contact with one end of the guide plate 2.

[0037] As Figure 1 shown, a traction rope is connected to one end of each guide plate 2. All the traction ropes in each group of flushing assemblies are clamped in a bundling block arranged at the free end of a suction tube 1.

[0038] The flushing assembly can assist medical staff in cleaning various channels of the patient's urinary system. According to the positional relationship between the part to be flushed and the suction tube 1, the traction rope bundle clamped in the corresponding cluster block is pulled, and the traction rope bundle will pull the guide plate 2 to rotate inward along the liquid guide window 22 opened on the outer side of the suction tube 1. When the guide plate 2 rotates inward, the position where the guide plate 2 was originally set at the liquid guide window 22 will be exposed. At this time, the suction pump connected to one end of the suction tube 1 is replaced with a liquid pump, and normal saline for flushing is pumped into the suction tube 1.

[0039] Specific usage method and function of this embodiment:

[0040] The crushing assembly provided in the present invention can perform secondary crushing on the stones blocking the suction end of the suction tube 1, avoiding the blockage of the suction tube 1 by the stones while performing secondary treatment on the stones, thereby improving the suction and discharge efficiency of the stones. When it is necessary to crush the stones on the crushing and bearing assembly, the support plate 5 and the rotating frame 11 are driven to rotate 270 degrees from the outside to the inside. After the rotating frame 11 rotates to the horizontal direction, the clamping plate 19 rotatably clamped at the top of the rotating frame 11 is driven to rotate to the vertical direction. The impact hammer 15 will rotate synchronously along the limiting hole 13 opened at one end of the sliding groove 14 with the sliding buttons 12 provided on both sides of it as the center until the impact hammer 15 rotates to align with the through hole opened on the support plate 5. Since the moving frame 17 is slidably clamped between the clamping plates 19 through the side groove 7, and at the same time, one end of the moving frame 17 is sleeved in the sleeve 18 connected to the free end of the control rod 10, when the control rod 10 shortens, it will pull the impact hammer 15 connected to the moving frame 17 through the connecting rod 16 to move downward along the through hole opened on the support plate 5. Driving the telescopic rod to repeatedly expand and contract can make the impact hammer 15 repeatedly impact the stones until the crushing is completed.

[0041] The above are only the embodiments of the present invention. Specific technical solutions and / or common knowledge such as characteristics well known in the art are 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 deformations and improvements can still be made, and these should also be regarded as the protection scope of the present invention, which will not affect the implementation effect of the present invention and the practicability of the patent. The protection scope required by this application should be based on the content of its claims, and the specific implementation manners described in the specification can be used to explain the content of the claims.
