Description
Technical field
The present invention relates to medical instrument technical field, be specifically related to a kind of apparatus for placing for scalable endoureteral stent.
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 apparatus for placing for scalable endoureteral stent 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 apparatus for placing for scalable endoureteral stent, 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, the two ends of described sheath pipe are equipped with opening, one end opening of sheath pipe connects source of the gas by pipeline, one end opening of sheath pipe and the inner chamber of stoma tube are connected, described stoma tube connects away from sheath pipe one end the termination of advancing, 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 apparatus for placing for scalable endoureteral stent, 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, the two ends of described sheath pipe 2 are equipped with opening, one end opening of sheath pipe 2 connects source of the gas 1 by pipeline, one end opening of sheath pipe 2 and the inner chamber of stoma tube 3 are connected, described stoma tube 3 connects away from sheath pipe 2 one end the termination 5 of advancing, described elastic ball film 4 is set in stoma tube 3 outsides, and 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 7, the both ends open of inner support 7, inner support 7 has an initial size, but while using external force that inner support 7 is outwards strutted from inside, inner support 7 can not bounce back, in the time that inner support 7 reaches pre-sizing, stop applying support force, inner support 7 stops deformation and keeps shape, if to inner support 7 to continue to apply support force, inner support 7 can recover (retraction) to original size again.In the time placing inner support 7, first inner support 7 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 7 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 7 is retained in stricture of ureter place, in the time needing the inner support 7 of indwelling to take out, apparatus for placing is stretched in ureter, the inner chamber of termination 5 through inner support 7 makes to advance, and by the position of corresponding inner support 7 elastic ball film 4, controlling source of the gas inflates, inner support 7 is continued to support large, make inner support 7 be subject to bouncing back to immediately initial size after power that this support is large, in retraction process, control venting, then apparatus for placing and inner support 7 are together taken out.
Further, the present invention can also arrange a through tube 8, this through tube 8 is located in sheath pipe 2 and stoma tube 3, stretch out from the open end of sheath pipe 2 its one end, the other end in the past inlet side 5 stretches out, in ureter, advance in process, can judge according to the liquid flowing out in through tube 8 whether this device has arrived stricture of ureter place, because having liquid, stenosis assembles, endoureteral stent apparatus for placing of the present invention, and 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.
