Abstract
The utility model discloses a composite cylindrical water-sac prostatic splitting catheter comprising a catheter body. The catheter body is internally provided with a urethral catheterication cavity, an internal sac cavity, an external sac cavity and a flushing cavity, wherein the rear parts of the front openings of the urethral catheterication cavity and the flushing cavity are provided with a composite cylindrical high-pressure water sac, the composite cylindrical high-pressure water sac comprises an internal sac and an external sac, the internal sac is arranged at the rear segment in the external sac, the openings at the front ends of the internal sac cavity and the external sac cavity are respectively arranged in the internal sac and the external sac, and the internal sac is shorter than the external sac and is arranged at the rear end of the external sac. During treatment, the internal sac is expanded to enable the urethra and the prostate to split and keep the neck of the bladder unchanged, and thus inward slipping of the catheter can be controlled conveniently; and the expanded external sac is in a cylindrical shape, so that the expansion effect is ensured, a urethral gap at the neck of the bladder is formed, and the diameter of the urethral gap is basically identical to the splitting diameter.
Description
Technical field
This utility model relates to a kind of prostate dilator, relates in particular to a kind of compound column water pocket prostate dilator.
Background technology
Adopting back urethra dilation operation treatment prostatic hyperplasia, is the method that present medical circle should pay attention to studying the treatment prostatic hyperplasia.
As shown in Figure 1, a kind of prostate dilator of the prior art, for the ease of inserting, external capsule is 01 rounded, spherical, arc or streamlined etc.
There is following shortcoming at least in above-mentioned prior art:
When external capsule was positioned the bladder neck pressurising, interior cunning was wayward, the expansion effect instability.
The utility model content
The purpose of this utility model provide a kind of in good, the compound column water pocket prostate dilator that can form basic identical bladder neck urethra gap of sliding control easily, expansion effect with the diameter that splits.
The purpose of this utility model is achieved through the following technical solutions:
Compound column water pocket prostate dilator of the present utility model, comprise catheter main body, be provided with urethral catheterization chamber, interior blister cavities, outer blister cavities, flushing chamber in the described catheter main body, the rear portion of the front opening in described urethral catheterization chamber and flushing chamber is provided with compound column water under high pressure capsule, described compound column water under high pressure capsule comprises capsula interna and external capsule, described capsula interna is positioned at the back segment of described external capsule, and the front end of described interior blister cavities and outer blister cavities is opened on respectively in described capsula interna and the external capsule, and the shape after the described external capsule expansion is column.
The technical scheme that is provided by above-mentioned this utility model as can be seen, compound column water pocket prostate dilator described in the utility model, because compound column water under high pressure capsule comprises capsula interna and external capsule, capsula interna is positioned at the back segment of described external capsule, and the shape after the external capsule expansion is column.In sliding control easily, expansion effect good, can form the basic bladder neck urethra gap identical with the diameter that splits.
Description of drawings
Fig. 1 is the structural representation of prostate dilator of the prior art;
Fig. 2 is the structural representation of the compound column water pocket of this utility model prostate dilator.
The specific embodiment
Compound column water pocket prostate dilator of the present utility model, its preferable specific embodiment as shown in Figure 2, comprise catheter main body 8, be provided with urethral catheterization chamber, interior blister cavities, outer blister cavities, flushing chamber in the catheter main body, the open rearward end in four chambeies is respectively 1A, 2A, 3A, 4A, and front opening is respectively 1B, 2B, 3B, 4B.The rear portion of front opening 1B, the 2B in urethral catheterization chamber and flushing chamber is provided with compound column water under high pressure capsule, compound column water under high pressure capsule comprises capsula interna 5 and external capsule 6, described capsula interna 5 is positioned at the back segment of described external capsule 6, opening 3B, 4B are in described capsula interna 5 and external capsule 6 respectively for the front end of blister cavities and outer blister cavities in described, and the shape after described external capsule 6 expansions is column.
The edge of the end of described column external capsule 6 can be provided with little fillet, and the radius of described little fillet is less than or equal to 2.5mm.
The rear end of described capsula interna 5 is concordant with the rear end of described external capsule 6, the length of described capsula interna 5 be less than or equal to described external capsule 6 length 3/4ths, such as the length of capsula interna 5 can for the length of described external capsule 6 1/4th, two/first-class.
The specific embodiment preferred sizes is:
The long 40cm of described catheter main body, external diameter 5mm; The length of described capsula interna 6 is 4.5-6cm, and the length of external capsule is 7-12cm, and the external diameter of the inside and outside capsule in back that expands is 2.4---4.4cm.
The catheter main body 8 at described external capsule 6 rear portions is provided with locator protrusions 7, and described locator protrusions 7 can be 1-1.5cm apart from the capsule tail of described external capsule.
Can insert the metal inner core in the catheter main body 8, the convenient insertion also can not inserted metal-cored as required.Capsula interna and external capsule all can be withstand voltage more than or equal to 0.45MPa.
Below principle of the present utility model is described in detail:
The main innovative point of this utility model is, external capsule is made column, has changed traditional external capsule is rounded, spherical, arc or structure such as streamlined, can guarantee that prostate is split and reach the purpose of treatment, and location easily, is difficult for being slipped in the bladder.
In this utility model, at the rear portion of external capsule a capsula interna is set, in the use, capsula interna has at first expanded, and makes in the therapeutic process to fix easily, and not to the intravesical landing, afterwards, external capsule expands, and treats.
As shown in Figure 1, in the prior art, capsula interna 03 and back capsula interna 02 before in external capsule 01, being provided with, and in the therapeutic process, preceding capsula interna 03 nearly forward end does not have pivotal role to treatment and location, makes complex structure on the contrary, uses, it is all inconvenient to make.The application has removed preceding capsula interna, and a capsula interna only is set at the rear portion of external capsule.
The application has changed the prejudice of this area custom, and sliding control easily in making, expansion effect is good, can form the basic bladder neck urethra gap identical with the diameter that splits.
The above; it only is the preferable specific embodiment of this utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that this utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.
