Abstract
The invention discloses a composite columnar water-bag prostate dilation catheter, which comprises a catheter main body. A catheterization cavity, an inner capsule cavity, an outer capsule cavity and a washing cavity are arranged in the catheter main body; the rear parts of the front openings of the catheterization cavity and the washing cavity are provided with a composite columnar high-pressure aqueous capsule; the composite columnar high-pressure aqueous capsule comprises an inner capsule and an outer capsule; the inner capsule is located at the rear section of the outer capsule; the front ends of the inner capsule cavity and the outer capsule cavity are opened in the inner capsule and the outer capsule respectively; the inner capsule is shorter than the outer capsule and located at the rear end of the outer capsule; during treatment, the inner capsule is expanded so that the urethra and the prostate on the part are dilated, while the neck of a bladder is kept at original state so as to conveniently control slide in the catheter. The expanded outer capsule is in a columnar shape so as to ensure the expansion effect and form a urethra gap with a size basically the same as the dilation diameter at the bladder neck.
Description
Technical field
The present invention relates to a kind of prostate dilator, relate 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, and expansion effect is unstable.
Summary of the invention
The purpose of this invention is to 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 objective of the invention is to realize through following technical scheme:
Compound column water pocket prostate dilator of the present invention; Comprise catheter main body, be provided with urethral catheterization chamber, interior blister cavities, outer blister cavities, flushing chamber in the said catheter main body, said urethral catheterization chamber is provided with compound column water under high pressure capsule with the rear portion of the front opening in flushing chamber; Said compound column water under high pressure capsule comprises capsula interna and external capsule; Said capsula interna is positioned at the back segment of said external capsule, and the front end of said interior blister cavities and outer blister cavities is opened on respectively in said capsula interna and the external capsule, and the shape after the said external capsule expansion is column.
Technical scheme by the invention described above provides can be found out, compound column water pocket prostate dilator of the present invention, because compound column water under high pressure capsule comprises capsula interna and external capsule, capsula interna is positioned at the back segment of said 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 the present invention prostate dilator.
The specific embodiment
Compound column water pocket prostate dilator of the present invention; Its preferable specific embodiment is 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 urethral catheterization chamber is provided with compound column water under high pressure capsule with the front opening 1B in flushing chamber, the rear portion of 2B; Compound column water under high pressure capsule comprises capsula interna 5 and external capsule 6; Said capsula interna 5 is positioned at the back segment of said external capsule 6; Opening 3B, 4B are in said capsula interna 5 and external capsule 6 respectively for the front end of blister cavities and outer blister cavities in said, and the shape after said external capsule 6 expansions is column.
The edge of the end of said column external capsule 6 can be provided with little fillet, and the radius of said little fillet is less than or equal to 2.5mm.
The rear end of said capsula interna 5 is concordant with the rear end of said external capsule 6, the length of said capsula interna 5 be less than or equal to said external capsule 6 length 3/4ths, such as the length of capsula interna 5 can for the length of said external capsule 6 1/4th, two/first-class.
The specific embodiment preferred sizes is:
The long 40cm of said catheter main body, external diameter 5mm; The length of said 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 said external capsule 6 rear portions is provided with locator protrusions 7, and said locator protrusions 7 can be 1-1.5cm apart from the capsule tail of said 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.
Carry out detailed description in the face of principle of the present invention down:
The main innovative point of the present invention 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.
Among the present invention, at the rear portion of external capsule a capsula interna is set, in the use, capsula interna has at first expanded, and makes easy fixation in the therapeutic process, 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; Be merely the preferable specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, any technical staff who is familiar with the present technique field is in the technical scope that the present invention discloses; The variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.
