Abstract
The utility model provides a device for preventing the crushed stone from flowing back to the renal pelvis through a ureter, which comprises a liquid pipe, a blocking end and a water inlet end, wherein the liquid pipe comprises two pipe cavities, namely a water sac pipe and a flushing pipe; the blocking end of the water bag pipe is provided with an expandable water bag, and the water inlet end is provided with a one-way elastic valve; the blocking section of the flushing pipe is provided with a water outlet, and the water inlet end is provided with a flushing pipe joint; the water sac can be filled to block the whole ureter after being expanded to form a blocking body; the water inlet ends of the water bag pipe and the flushing pipe are Y-shaped pipe orifices; the liquid pipe is also provided with a graduated scale. The utility model discloses simple structure, design scientific and reasonable can effectually prevent rubble, the problem of sparge water adverse current to renal pelvis at the in-process of the garrulous operation of ureteroscope.
Description
Technical Field
The utility model belongs to the field of medical equipment, concretely relates to device that prevents that garrulous stone ureter flows against current to renal pelvis.
Background
At present, ureteral calculus backflow prevention is a net structure used for preventing ureteral calculus backflow during calculus breaking, and due to the fact that the net structure is net, the ureteral calculus backflow prevention only can prevent large calculus backflow and is ineffective in small calculus backflow, and calculus recurrence is caused. The scheme is designed for completely preventing the stone from flowing backwards, the tail end of the scheme is cystic, the tail end of the scheme is tightly attached to the ureter after being expanded, the backflow path of large and small stones is blocked, and the saccular elasticity of the scheme is difficult to puncture by stones.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a device of garrulous stone through ureter adverse current to renal pelvis, the utility model discloses simple structure, design scientific and reasonable can effectually prevent rubble, sparge water problem to renal pelvis in the in-process of the garrulous operation of ureteroscope.
The technical scheme of the utility model:
the utility model provides a device for preventing broken stones from flowing back to the renal pelvis through the ureter, which comprises a liquid pipe, a blocking end and a water inlet end, wherein the liquid pipe comprises two pipe cavities, namely a water sac pipe and a flushing pipe; the blocking end of the water bag pipe is provided with an expandable water bag, and the water inlet end is provided with a one-way elastic valve; the blocking section of the flushing pipe is provided with a water outlet, and the water inlet end is provided with a flushing pipe joint; the water bag can be filled to cover the back side of the whole water outlet after being expanded to form a blocking body; the water inlet ends of the water bag pipe and the flushing pipe are Y-shaped pipe orifices; the liquid pipe is also provided with a graduated scale.
The utility model discloses a general concept: the design of double-barrelled pipe is favorable to binding different pipelines on same operating equipment, and one of them lumen is the circulation pipeline of water pocket, can pack in importing the water pocket with outside support liquid, and another lumen is the wash pipe, and at the in-process of ureteroscope rubble, through the inflation of water pocket, the whole ureter lumen leading to renal pelvis is stopped up, and rubble, sparge water can only flow toward the bladder, and then play and prevent through the ureter effect of flow against the current to renal pelvis. The outer pipe wall of the liquid pipe is also provided with scale marks, so that the extending distance can be visually judged.
Further, the liquid tube is a transparent and visible plastic tube.
Furthermore, the elastic valve adopts a valve cover body with a one-way circulation flap structure.
The utility model has the advantages that:
1. the ureter cavity is blocked by the expansion of the water bag, and the ureter can be flushed through the flushing pipe interface, so that the effect of preventing the ureter from flowing back to the renal pelvis is achieved.
2. The outer pipe wall of the liquid pipe is also provided with scale marks, so that the extending distance can be visually judged.
3. The utility model discloses simple structure, design scientific and reasonable can effectually prevent rubble, the problem of sparge water adverse current to renal pelvis at the in-process of the garrulous operation of ureteroscope.
