Abstract
The utility model relates to a prostate capsule dilating catheter, in particular to a double-bladder positioning catheter for dilating prostate capsule. The double-bladder positioning catheter comprises a catheter body, and is characterized in that a urethral catheterizing cavity, an irrigating cavity, a front bladder cavity and a rear bladder cavity are arranged in the catheter body. The four cavities are respectively provided with front end openings. The front bladder cavity is arranged on the rear portions of the front end openings of the urethral catheterizing cavity and the irrigating cavity. The rear bladder cavity is arranged behind the front bladder cavity in parallel. The front openings of the urethral catheterizing cavity are two holes; and the front opening of the irrigating cavity is a single hole. In a treatment, the rear bladder cavity is dilated at first to dilate a urethra in the prostate capsule and parts of the prostate, and then the front bladder cavity is dilated to dilate the bladder neck and parts of the prostate so as to guarantee dilation effect that a urethra width of the bladder neck is basically the same as a dilating diameter, and operations during and after a surgery are facilitated.
Description
Technical field
This utility model relates to a kind of capsula prostatica and expands conduit, relates in particular to a kind of pair of capsule location capsula prostatica and expands conduit.
Background technology
It is the former internal organs of unique reservation in present many operation on prostate that present stage adopts capsula prostatica to expand art treatment hyperplasia of prostate, keep former function, wound is atomic, safety coefficient is high, and obtain Chinese Medicine health service " outstanding achievement " prize, be worth research, promote.
A kind of prostate dilator of the prior art, the rear portion of the urethral catheterization chamber of this conduit and the front opening 1B, the 2B that rinse the chamber is provided with the compound column water under high pressure capsule of capsula interna 5 and external capsule 6 formations, as shown in Figure 1.There is following shortcoming in above-mentioned prior art: 1, capsula interna is hidden in external capsule, and the location blindly; 2, complex structure, in a single day capsule breaks, and patient is hemorrhage more, must change conduit; 3, the postoperative conduit can't be fixed, easily slippage.If fix with the water filling of column external capsule, patient is more painful; 4, the front end side opening in urethral catheterization chamber is only one, and drain owes freely and easily to be stopped up by clot; 5, keep intraluminal pressure more difficult; 6, postoperative regularly reduces pressure loaded down with trivial details.Due to the problems referred to above that this prostate dilator exists, had a strong impact on effect and the quality for the treatment of.
The utility model content
In order to address the above problem, this utility model provides a kind of accurate positioning, it is effective to be difficult for sliding, to expand, and in art, easy-operating pair of postoperative capsule location capsula prostatica expands conduit.
The purpose of this utility model is achieved through the following technical solutions: a kind of pair of capsule located capsula prostatica and expanded conduit, comprise catheter main body, be provided with the urethral catheterization chamber in catheter main body, rinse chamber, front blister cavities, rear blister cavities, described four chambeies are respectively equipped with front opening, described urethral catheterization chamber is front blister cavities with the rear portion of the front opening that rinses the chamber, blister cavities after the rear portion parallel arranged of front blister cavities; The front opening in described urethral catheterization chamber is two holes, and the front opening that rinses the chamber is single hole.
The length of described catheter main body is 38cm, and external diameter is 0.7cm; Be barrel-shaped after front blister cavities is full, its length is 3cm, is tubbiness after rear blister cavities is full, and its length is 4 ~ 10cm, and when full, forward and backward blister cavities external diameter is 3.2 ~ 3.9cm.
The catheter main body of described rear blister cavities afterbody is provided with hemispherical protuberances, the rear blister cavities afterbody of described hemispherical protuberances distance 1 ~ 2cm.In addition, after the external two-way of water injection conduit or three-way cock of front blister cavities and rear blister cavities open rearward end, then connect Pressure gauge.
Found out by the technical scheme that this utility model provides, described in the utility model pair of capsule located capsula prostatica and expanded conduit, due to before the urethral catheterization chamber, two holes are arranged, drain is more abundant, and the existing dilating effect of front blister cavities can be used for again the A/C effect, anti-slip positioning can be expanded and have to rear blister cavities, guaranteeing that capsula prostatica expands, form the basic bladder neck urethra gap identical with expanding diameter, make in art postoperative easy to operate.
Description of drawings
Fig. 1 is the structural representation of prostate dilator of the prior art;
Fig. 2 is that the two capsules of this utility model are located the structural representation that capsula prostatica expands conduit.
The specific embodiment
The structure that of the present utility model pair of capsule location capsula prostatica expands conduit as shown in Figure 2.This pair capsule location capsula prostatica expands conduit, comprises catheter main body A, is provided with the urethral catheterization chamber in catheter main body, rinses chamber, front blister cavities, rear blister cavities, and the front opening in four chambeies is respectively A1, A2, A3, A4, and open rearward end is respectively B1, B2, B3, B4.The rear portion of described urethral catheterization chamber and the front opening that rinses the chamber is barrel-shaped front blister cavities B after full, be barrel-shaped rear blister cavities C after the rear portion parallel arranged of front blister cavities B is full, the front opening A1 in described urethral catheterization chamber is two holes, the long 7mm in every hole, wide 3 ~ 5mm, the front opening A2 that rinses the chamber is single hole, and this single hole is that square hole or the diameter of 1.5 * 1.5mm is the circular hole of 1.5mm.
The length of catheter main body A is 38cm, and external diameter is 0.7cm; Front blister cavities length is 3cm, and rear blister cavities length is 4 ~ 10cm, and when full, forward and backward blister cavities external diameter is 3.2 ~ 3.9cm.
Front blister cavities and rear blister cavities all can be withstand voltage more than or equal to 0.48MPa.The catheter main body of described rear blister cavities afterbody is provided with semicircular projection D, the rear blister cavities afterbody of described semicircular projection D distance 1 ~ 2cm, and this semicircular projection is as external telltale mark.
Front opening A3, the A4 of described front blister cavities and rear blister cavities is located at respectively in described front blister cavities B and rear blister cavities C, after the external two-way of the water injection conduit of both open rearward end B3, B4 or three-way cock, then connects Pressure gauge.
In addition, the upper syringe pipe length 15cm that connects of catheter main body A afterbody open rearward end B2, the water injection pipe length that front blister cavities open rearward end B3 connects is 50cm, the upper water injection pipe length that connects of rear blister cavities open rearward end B4 is 40cm.
Below in conjunction with above-mentioned, principle of the present utility model is described:
