Abstract
The invention relates to a ureter internal stent placement device. The ureter internal stent placement device comprises an air source, a sheath catheter, an air hole pipe, an elastic spherical membrane and an advancing tip. A plurality of vent holes are formed in the side wall of the air hole pipe. Both the two ends of the sheath pipe are closed. One end of the sheath pipe is connected with the air hole pipe. The other end of the air hole pipe is connected with the advancing tip. A ventilation pipe penetrates through the sheath pipe. Both the two ends of the ventilation pipe penetrate through the sheath pipe. One end of the ventilation pipe is connected with the air source. The other end of the ventilation pipe is arranged in a cavity of the air hole pipe. The air hole pipe is sleeved with the elastic spherical membrane. The elastic spherical membrane is connected with the air hole pipe in a sealed mode. The ureter internal stent placement device is simple in structure, an internal stent can be placed in a narrow position of a ureter, the whole placement process is simple and rapid, the success rate of surgeries is high, the normal backflow prevention mechanism of the ureter is not changed, urine in the bladder can be prevented from flowing back to the pelvis, occurrence of nephropyelitis and exacerbation of symptoms of hydronephrosis can be avoided, pains of patients can be reduced, and quality of life of patients can be improved.
Description
Technical field
The present invention relates to medical instrument technical field, be specifically related to a kind of endoureteral stent apparatus for placing.
Background technology
On clinical medicine, stricture of ureter refers to because a variety of causes is directed at ureter tube cavity segment or full section compared with normal is narrow and small, although the seriality of tube chamber is not interrupted, has caused upper urinary tract obstruction and hydronephrosis in various degree.Except congenital reason, inflammation, damage and operative scar are main causes.Treating ureteral a kind of wherein method is at ureteral stenosis indwelling inner support, prior art is mainly through cystoscope or ureteroscope and is implanted into after seal wire to ureter, push two " J " type endoureteral stents along seal wire, its upper end is inserted renal pelvis lower end and is placed in bladder, operation process is loaded down with trivial details, and the postoperative two-way permeability due to two " J " type endoureteral stent, change ureteral normal anti-reflux mechanism, with intravesical urine pressure raise or patient when the horizontal position bladder position higher than kidney, also can cause that intravesical urine backflows in renal pelvis, cause pyelonephritis or increase the weight of the hydrops degree of kidney, have a strong impact on surgical effect, limit patient's daily life.Thereby how quick, easily inner support to be inserted to stricture of ureter place, and reduce postoperative infection and avoid increasing the weight of of hydronephrosis symptom, the quality of life of improving patient is the problem of needing solution badly.
Summary of the invention
The object of the invention is the deficiency for solving the problems of the technologies described above, a kind of endoureteral stent apparatus for placing is provided, simple in structure, inner support can be placed in to ureteral stenosis, whole put procedure is simple, fast, success rate of operation is high, and does not change ureteral normal anti-reflux mechanism, can avoid intravesical urine to backflowing in renal pelvis, can avoid the generation of pyelonephritis and increasing the weight of of hydronephrosis symptom, alleviate patient's misery, improve patient's quality of life.
The present invention is the deficiency solving the problems of the technologies described above, the technical scheme adopting is: a kind of endoureteral stent apparatus for placing, comprise source of the gas, sheath pipe, stoma tube, elastic ball film and the termination of advancing, on the sidewall of stoma tube, be provided with multiple passages, sheath pipe two ends are all sealed, one end of described sheath pipe connects stoma tube, the other end of stoma tube connects the termination of advancing, in sheath pipe, be equipped with breather, the two ends of breather all arrange through sheath pipe, one end of breather is connected with source of the gas, the other end of breather is arranged in the cavity of stoma tube, described elastic ball Membrane cover is located at stoma tube outside, elastic ball film and stoma tube junction are for being tightly connected.
The described termination of advancing is for cone column construction, the cone point stoma tube setting dorsad of the termination of advancing.
beneficial effect
Endoureteral stent apparatus for placing of the present invention, simple in structure, inner support can be placed in to ureteral stenosis, whole put procedure is simple, quick, success rate of operation is high, and do not change ureteral normal anti-reflux mechanism, can avoid intravesical urine to backflowing in renal pelvis, can avoid the generation of pyelonephritis and increasing the weight of of hydronephrosis symptom, alleviate patient's misery, improve patient's quality of life.

The specific embodiment
As shown in the figure: a kind of endoureteral stent apparatus for placing, comprise source of the gas 1, sheath pipe 2, stoma tube 3, elastic ball film 4 and the termination 5 of advancing, on the sidewall of stoma tube 3, be provided with multiple passages 6, sheath pipe 2 two ends are all sealed, one end of described sheath pipe 2 connects stoma tube 3, the other end of stoma tube 3 connects the termination 5 of advancing, in sheath pipe 2, be equipped with breather 7, the two ends of breather 7 all arrange through sheath pipe 2, one end of breather 7 is connected with source of the gas 1, the other end of breather 7 is arranged in the cavity of stoma tube 3, described elastic ball film 4 is set in stoma tube 3 outsides, elastic ball film 4 and stoma tube 3 junctions are for being tightly connected.The described termination 5 of advancing is for cone column construction, and the cone point of the termination 5 of advancing dorsad stoma tube 3 arranges.The termination 5 of advancing of this structure can make apparatus for placing more easily move in ureter,
The inner support that inner support apparatus for placing of the present invention is placed has following characteristics, the cylindrical shape of this inner support 8, the both ends open of inner support 8, inner support 8 has an initial size, but while using external force that inner support 8 is outwards strutted from inside, inner support 8 can not bounce back, in the time that the external force that struts it does not exist, inner support 8 stops deformation and keeps shape, in the time placing inner support 8, first inner support 8 is set in to the outside of stoma tube 3, then whole device stretches to stenosis along ureter, utilization is advanced the shape of termination 5 through this stenosis, inner support 8 is just strutted stenosis, then controlling source of the gas 1 inflates, gas enters elastic ball film 4 inside from the passage 6 of stoma tube 3, elastic ball film 4 is heaved, elastic ball film 4 can be strutted from the inside of inner support after heaving, after support extremely to a certain degree, controlling source of the gas 1 exits, it is flat that elastic ball film 4 can become, then whole apparatus for placing is extracted out, inner support 8 is retained in stricture of ureter place.Endoureteral stent apparatus for placing of the present invention, simple in structure, inner support can be placed in to ureteral stenosis, whole put procedure is simple, and quick, success rate of operation is higher.
