Abstract
The present invention is a kind of conduit for the treatment of ureteral calculus, and it has three tube chambers and two eccentric balloons.This conduit inserts ureter through bladder, when the head of conduit surpasses calculus with its air bag subsequently, stop intubate, make two balloon occlusion ureters from the opening water filling of catheter tail, again by the ureter between two air bags of another opening water filling expansion of catheter tail, quicken the water filling calculus of can getting excited and shift to ureter distal and enter bladder at last.The present invention is applicable to the calculus at the omnidistance any position of treatment ureter, and it cooperates with ESWL can improve the calculus degradation rate and impel the rubble discharge, this conduit safe and reliable, easy to operate, good effect.
Description
The present invention is a kind of double balloon catheter for the treatment of ureteral calculus.
Adopt the conduit of approach treatment ureteral calculus in the tube chamber to be called cover stone implement or dislodger at present, they are a kind of thin and long hollow plastic catheters, the calculus catching net-like means or the lithotomy forceps that have a steel wire to make in the catheter lumen are by the steel wire control calculus catching net-like means of conduit other end opening or the switching of lithotomy forceps.This conduit is inserted into ureter through cystoscope, after it entangles or vises calculus, utilizes conduit that calculus is hauled out from ureter again.The success rate of this catheter treatment ureteral calculus and not really high reason may be that calculus catching net-like means or lithotomy forceps are not easy to entangle or vise calculus, and it is dissatisfied also may to be that calculus catching net-like means or lithotomy forceps open in the high ureteral lumen of tension force, also may be other reason; Can cause the damage by friction of ureter wall when the calculus that will entangle or vise is hauled out in addition from ureter.Even operation under the x-ray tv screen also might be clamped the avulsion injury that causes mucous membrane of ureter with ureter wall together when entangling or vising calculus.Though on the cover stone implement that has or the conduit of dislodger air bag has been installed, owing to do not change the basic method of this catheter treatment ureteral calculus, so the problems referred to above still exist.As for trap in the ureteroscope direct-view stone or pincers stone, the problems referred to above and other problem also still can appear.
A kind of double balloon catheter provided by the invention is specifically designed to the treatment ureteral calculus.
The present invention be one thin and grow, smooth surface, have graduated three chamber double balloon catheters.An air bag is being arranged near catheter head, the opening by catheter tail can make air inject this air bag and make it to expand; Against this air bag back a tube chamber opening is arranged, the liquid that another opening by catheter tail injects can flow out from this opening; There is second air bag at about 3～8Cm place apart from the air bag of catheter head, injects air through the opening of catheter tail and can make this airbag inflation.Three tube chambers of conduit are obstructed each other.The using method of conduit is: be inserted into ureter at cystoscope direct-view downcomer, catheter head is round and thin, can be easy to pass the slit between calculus and the ureter inwall, when catheter head is guiding after first air bag crosses calculus, stop intubate, injecting contrast agent through the opening of catheter tail in first air bag makes it to expand and made it tensile to stretch tight at the ureter inner chamber, this moment can be through the very low contrast agent of another opening implantation concentration of catheter tail, and contrast agent enters more than the calculus from the catheter wall opening at swelling gasbag rear, in the ureteral lumen below the swelling gasbag.On the x-ray tv screen, can see, this section ureteral lumen is because the air bag that the upper end is inflated seals, and hydrops is expanded by Stone obstruction in the lower end, and water flows to bladder around conduit and calculus, at this moment utilize second air bag of the opening conductive pipe of catheter tail to inject air, slowly make it to expand.Because this air bag has produced the effect of blocking to imperfection ureteral lumen gradually, so the ureter of calculus below is hydrops expansion gradually also, calculus is positioned at the ureteral lumen that upper and lower is all expanded, the resistance that it moves down is very little, mobile in addition contrast agent will rush at ureter distal to calculus, enters bladder at last.
The present invention utilizes the circumscribed expansion ureter of hydraulic pressure, and utilizes the impulse force of liquid flow that calculus is moved down, and not only the frictionally damage to mucous membrane of ureter is little for this, and can carry out calculi therapy at same ureter repeatedly.Use the present invention can treat the calculus of any position of omnidistance ureter, method is simple, and is faint to the influence that renal pelvis is intrinsic pressure.Therefore it can point out a kind of new method for the treatment of ureteral calculus.
Concrete structure of the present invention is provided by the following drawings and explanation:
Fig. 1 is a structural representation of the present invention.
Fig. 2 be among Fig. 1 along the profile of A-A line, its air bag is an inflated condition.
Fig. 3 is use principle figure of the present invention.
According to Fig. 1, conduit (1) is one three a chamber double balloon catheter, and it is carefully grown, and little round end and three tails that have tube chamber of a taper are arranged, and its radiopaque slick tube wall is marked with scale; Conduit (1) is to be made by nontoxic plastic cement or TEELON.Can be crooked, its diameter is not more than F
r10; Three tube chambers (2), (4) and (5) are arranged in the conduit (1), and tube chamber (4) is the thickest tube chamber in the conduit (1); Two air bags (3) and (6) are arranged on the conduit (1), and airbag chamber communicates with tube chamber (2) and (5) through opening (2 ') and (5 ').The wall of air bag is to make with the thin latex that is bonded on conduit (1) outer wall; Thin latex balloon wall is wrapping tightly conduit (1), and when the opening (2 ") by conduit (1) afterbody and (5 ") injection air, air bag (3) and (6) can expand into cylindrical.The opening (4 ') of tube chamber (4) is the rear of air bag (3) and then, shape is at an angle on the sidewall of conduit (1) for opening (4 '), the liquid that this angle can make tube chamber (4) is when opening (4 ') sprays, and its ray is as far as possible towards the afterbody of conduit (1).Three tube chambers that expand gradually of conduit (1) afterbody can be installed switchette again.
According to Fig. 2, air bag (6) expands after inflating, because the latex wall thickness difference of air bag (6), so conduit (1) is not positioned on the center of circle of swelling gasbag (6), but is partial to a side.It is the same that the situation of air bag (3) can be contrasted air bag (6).
According to Fig. 3, conduit (1) is inserted into ureteric orifice (13) through bladder (12), and the head of conduit (1) and air bag (5) and opening (4) are all crossed calculus (14); Through tube chamber (2) water filling, water (flow) direction is marked by arrow among the figure.Water has not only been expanded the ureter of calculus (14) top, and current have produced the effect that promotion calculus (14) moves, hydraulic pressure is stopped by air bag (3) can not have influence on renal pelvis (9), inject air through tube chamber (5) air bag (6) is expanded, this can increase the resistance that current are located by ureter (10).Thereby make ureter (10) the expansion hydrops of air bag (6) top.Calculus (14) is in up and down in the ureteral lumen of all expansions, and the impulse force of current in addition is so can shift to distal ureter (11) easily.From as can be seen above: after expanding in air bag (3) and (6), conduit (1) is in eccentric position and is close to ureter wall, can make the moving resistance of the unlikely increase calculus of conduit (1) (14) like this.Water flows to bladder (12) from ureter (11), excretes through catheter (7).
