Abstract

The utility model relates to an image-display sphere bag inflatable dilator. The utility model is composed of a catheter, a head of the terminal port at one end of a closed catheter, an inside sphere bag and an outside sphere bag which are sheathed on the catheter and whose two heads are bound and sealed, developer solution injected into a gap between the two sphere bags, spacing sleeves sheathed on the inside sphere bag and the outside sphere bag, and a pressure gauge for the inflated bag. The pressure gauge for the inflated bag matches the spacing sleeve. After the inside sphere bag is inflated, the developer solution in the gap is uniformly distributed in the gap between the two sphere bags. The utility model can develop clearly under X-ray fluoroscopy and observe the expansion degree of narrow regions directly. The utility model is suitable for the expansion of the regions of esophagus stenosis, proventriculus stenosis, aorta stenosis, heart valve stenosis.

Description

Image-display sphere bag inflatable dilator

This utility model belongs to a kind of medical apparatus and instruments that is used to expand the human body organ inner bore narrow.

Existing balloon dilatation catheter Fig. 1 that is used to expand the human body organ inner bore narrow, it is that an end of the conduit 3 used by a common interventional radiology, conduit 3 is by end socket 1 sealing, be with tube-like thin-wall sacculus 2 inflatable and that shrink from end socket 1 one section conduit inwards, be in that design on the tube wall of conduit 3 of sacculus inner segment has expansion or the air inlet/outlet K1 when shrinking constitutes.When clinical use, the opening of conduit 3 connects pressurised airbag, and the appendix of air bag is connected to the air gauge of the observation pressure that communicates with appendix, under x-ray fluoroscopy because each histoorgan overlapping, balloon wall is not developed, and dilator is difficult to grasp in the degrees of expansion of human body organ inner bore narrow.

The purpose of this utility model is to disclose to people a kind ofly to be used to expand the narrow portion of human body organ inner bore and can to show clearly under x-ray fluoroscopy that narrow positions is by the development balloon dilatation catheter of degrees of expansion.

This utility model is realized by following proposal

The development balloon dilatation catheter, it comprises the conduit that a common interventional radiology is used, the mouth of pipe of conduit one end is by end socket or stopper or binding agent sealing, be with the thin-walled tubular sacculus (interior sacculus) of the gradually thin inflatable and contraction of two ends on blind end one section conduit inwards, the two ends of tubular sacculus is pricked knot together by tying up machine and conduit.Air inlet/outlet when design has balloon expandable and contraction on the duct wall in being in the sacculus.In the tube-like thin-wall periphery of sacculus be with one with the big or small identical thin-walled tubular ectosphere capsule of tube-like thin-wall endosphere scrotiform shape.Earlier the port of outer sacculus one end of tube-like thin-wall is pricked knot together by the termination conduit of colligation and interior sacculus, inject the positive developer solution of X line between the slit outside tube-like thin-wall between the inwardly outer balloon wall of the port of the sacculus other end, then the port colligation of outer sacculus is sealed.The periphery of outer sacculus is with the stop collar of the gradually thin thin-walled nylon fabrics of two ends cylindraceous, the stop collar two ends is by colligation and inside and outside sacculus, conduit is pricked knot together, after holding gas injection from the worn-out mouth of conduit by pressurised airbag, inside and outside sacculus begins to expand, in the slit inside and outside apparent agent solution is uniformly distributed between the sacculus, and stop collar has limited the maximum swelling volume of inside and outside sacculus.Also play the protection sacculus simultaneously, prevent disruptive effect.

Also pressurised airbag need be arranged during use, Pressure gauge matches with it, and its specific requirement is: the airway of pressurised airbag is connected with the conduit of development balloon dilatation catheter, and Pressure gauge is connected with the airway of pressurised airbag.

Advantage and effect:

The development balloon dilatation catheter is when expansion human body organ inner bore narrow positions, inject in the slit that can be uniformly distributed in after the inflation of the developer solution in the slit between two balloon wall between two balloon wall, clear development under x-ray fluoroscopy, thus clearly observe the degree that the organ lumen narrow positions is expanded.Because the outermost of sacculus is with the gradually thin tubular stop collar in two of nylon fabrics, thereby effectively limits the expanding volume of sacculus, guarantee that sacculus can be because of not inflating excessive explosion, Pressure gauge also observes directly the pressure state in the sacculus simultaneously simultaneously.It is applicable to that esophageal stricture, preventricular stenosis, trunk are narrow, the expansion of valvular stenosis the development balloon dilatation catheter.

Fig. 1 is the balloon dilatation catheter of prior art, and 1 is the end socket of conduit 3 terminations among the figure, the 2nd, and tubular sacculus, K ₁Be the air inlet/outlet on the duct wall that is in the sacculus 2, T ₁, T ₂It is the fixing seal mouth of sacculus two ends.

Fig. 2 is the structure chart of development balloon dilatation catheter.4 is end sockets, the 5th of conduit one end termination among the figure, nylon tubular stop collar, the 6th, thin-walled tubular ectosphere capsule, the 7th, X line positive contrast agent solution, the 8th, thin-walled tubular endosphere capsule, the 9th, conduit.

Fig. 3 is the partial enlarged drawing of Fig. 2 I.

The development balloon dilatation catheter as shown in Figure 2, it comprises the conduit 9 of the usefulness that gets involved that classes are over, the end socket 4 of the closes ducts 9 one end mouths of pipe, be enclosed within sacculus in inboard one section supravasal inflatable and fusiform tubular sacculus of the thin-walled 8(that shrinks of end socket 4); the two ends of thin-walled tubular sacculus is in the air inlet/outlet K when design has sacculus 8 expansions or contraction on the tube wall of the conduit 9 in the thin-walled tubular sacculus 8 by colligation and conduit 9 colligations together ₂The periphery of thin-walled tubular sacculus 8 is with the thin-walled tubular sacculus 6 identical with sacculus 8, one end of sacculus 6 adopts the method and the conduit 9 of colligation, sacculus 8 is pricked knot together, to between the slit between sacculus 8 and the sacculus 6, inject the cardiografin of 76% the Compound Diatrzoatc Meglumlne that can under the X-ray line, develop or 60% or 40% iodized oil from the another port of sacculus 6, then the port colligation is sealed.The periphery of thin-walled tubular sacculus 6 is with the gradually thin thin-walled nylon fabrics stop collar 5 of two ends of a tubular, and two ends is pricked knot together by colligation and sacculus 8, sacculus 6, conduit 9.
