Abstract

The invention discloses a stent pipe for a ureter and relates to the field of medical devices. The stent pipe comprises a hollow pipe body arranged in the ureter of a patient as well as a first curly section and a second curly section which are arranged at two ends of the hollow pipe body respectively, wherein the first curly section is arranged in the bladder of the patient; the second curly section is arranged in the renal pelvis of the patient; multiple first through holes are evenly formed in the first curly section; multiple second through holes are evenly formed in the second curly section; a pipe is connected to outlet sides of the second through holes; a check valve is further arranged in the hollow pipe body and comprises a valve body and a ball body located at an outlet end of the valve body; the valve body is tubular; a first inner taper surface is arranged at the outlet end of the valve body. The stent pipe has the double anti-reflux effect, and reflux of urine is effectively prevented.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a ureteral stent tube. Background technique [0002] In recent years, it has been clinically adapted to diseases such as upper urinary tract obstruction and hydronephrosis caused by ureteral stenosis caused by kidney stones, ureteral stones, and other various reasons (such as inflammatory stenosis, stenosis after radiotherapy, etc.). The upper urinary tract obstruction and dilated water caused by this will seriously damage the renal function, and in severe cases will lead to the loss of renal function and endanger the health of the patient. [0003] In the past, such patients were usually treated clinically with implantation and indwelling of ureteral stents, which delayed or prevented further damage to renal function and provided the possibility and opportunity for further surgery. The patient relieved the pain caused by the disease, and reduced the risk of postoperative uret...
