Definitions
- the present invention generally relates to a catheter for treating benign prostatic hyperplasia, and more particularly, to a catheter for treating benign prostatic hyperplasia which can be used for treatment after treatment of prostate hyperthermia and prostatectomy.
- Prostatic hyperplasia is a condition in which the balance of the whole hormone is disrupted by aging, and a nodule develops in the prostate, which enlarges and enlarges the urethra. Prostate hyperplasia makes urination difficult, and various treatments have been used. Typical treatments include drug therapy, resection, and hyperthermia.
- the present invention is directed to a catheter used for prostatectomy and prostate hyperthermia.
- Catheters used in prostatectomy are used to remove exudate from the bladder and to compress the prostate during or after partial prostatectomy.
- Prostate hyperthermia is a treatment that applies heat to the abnormal prostate tissue to shrink the tissue.
- a catheter is used to perfuse and wash the exudate and blood in the bladder. No catheter has ever been able to simultaneously flush the bladder with exudate, blood, etc., and perform prostate compression and hemostasis.
- catheters used for prostatectomy there are two types of catheters used for prostatectomy: double balloon type and single balloon type.
- double-balloon catheter two balloons are separately provided in series at the distal end of the catheter, and the distal balloon (capacity of 5 to 10 cc) is used for indwelling the catheter in the bladder. (0 cc or more) is used for compressive hemostasis at the prostatectomy.
- the single-balloon catheter omits the bladder indwelling balloon and uses only a compression hemostasis balloon (capacity of 30 cc or more). The tip of the single 'balloon catheter was once inserted into the bladder, the balloon was pulled back to the prostate position, and the balloon was then inflated to perform compression hemostasis.
- the catheter used for prostate hyperthermia is a single balloon type equipped with only a balloon for indwelling the bladder.
- prostate hyperthermia Immediately after the procedure, the atrophied prostate tissue was found to tend to slightly expand and recover.
- the above-described double-balloon catheter can suppress the expansion and restoration of the atrophied prostate tissue by compressing the heated tissue.
- a compression hemostasis balloon is originally designed in a spherical shape for compression hemostasis, the balloon may be displaced from the prostate when the balloon is inflated, or the compression may be uneven. As a result, the heated prostate tissue cannot be properly compressed.
- an object of the present invention is to provide a catheter capable of simultaneously performing prostatic compression hemostasis and perfusate infusion washing, so that it can be used for prostatectomy and prostate hyperthermia.
- a catheter for treating prostatic hypertrophy includes a catheter body having a perfusion passage, a first fluid passage, and a second fluid passage, and a fluid infusion provided integrally with the proximal end of the catheter body and communicating with each passage.
- a branch member having an extraction port, a first balloon for indwelling in the bladder, which is provided at the distal end of the catheter body and communicates with the first fluid passage, and which is provided at the distal end of the catheter body and is more than the first balloon. It comprises a second balloon for prostate compression provided on the upstream side and communicating with the second fluid passage, and a distal end stopper provided on the distal end of the catheter body.
- the catheter body may be provided with an implantable contrast line as needed.
- the thickness of both ends of the second balloon is smaller than the thickness of the middle portion, or the outlet of the second passage communicating with the second balloon. It is preferable to provide a plurality of these in the longitudinal direction of the catheter body.
- FIG. 1 is a plan view of a catheter for treating benign prostatic hyperplasia according to the present invention.
- FIG. 2 is a cross-sectional view of each part of the catheter of FIG. 1, and (A;), (B), (C), and (D) are respectively 2A-2A and 2B-2 of FIG. B, 2C—2C, 2D—2D view.
- FIG. 3 is an enlarged plan view of the distal end portion of the catheter shown in FIG.
- FIG. 4 is a drawing similar to FIG. 3 and shows a state in which each balloon is inflated.
- FIG. 5 is a partially enlarged sectional view of a part of FIG.
- FIG. 6 is an explanatory view showing an example of use of a catheter for treating benign prostatic hyperplasia based on the present invention.
- FIGS. 1 to 6 an embodiment of a power table for treating prostatic hyperplasia based on the present invention will be described.
- the catheter 100 for treating benign prostatic hyperplasia mainly comprises a catheter body 1, a branch member 2, a first balloon, and a second balloon. It consists of a balloon 4 and a tip end 5.
- the catheter body 1 has a perfusion channel 11, an implanted contrast line 12, a first fluid channel 13, a second fluid channel 14, and a urination channel 15.
- the implantation contrast line is embedded in the catheter body 1 as necessary.
- the catheter body 1 is made of silicon rubber, latex, or the like, and the embedding contrast line 12 is made of barium sulfate. Since the catheter body made of silicone rubber or the like has good lubricity and exfoliation property, it is most suitable for the catheter for treating prostatic hypertrophy of the present invention.
- the branch member 2 is provided integrally with the proximal end of the catheter main body 1 and has a fluid injection / extraction port communicating with each passage.
- the perfusion liquid inlet 21 (the female connector 2 11 and the cap 2 12 are connected to the inlet 21) is connected to the perfusion passage 11, while the first fluid passage 13 is connected to the first fluid passage 13.
- Fluid injection / extraction port 2 3 (One-way valve 2 31 is connected to injection / extraction port 23, and a first color tape (for example, red tape) 2 32 is wrapped around the port for a mark.)
- the second fluid passage 14 has a second fluid inlet / outlet port 24 (a one-way valve 24 1 is connected to the inlet / outlet port 24, and a second color tape (not shown) is provided on the outer periphery of the port for a mark. For example, a blue tape) 242 is wound.), And a urination outlet 15 1 is connected to the urination passage 15.
- the first balloon 3 for indwelling in the bladder is provided at the distal end of the force-telephone main body 1 as shown best in FIGS. (Fig. 2 (C)).
- a second balloon 4 for prostate compression is provided at the distal end of the catheter body 1 and upstream from the first balloon 3, as best shown in FIGS. And is connected to the outlet 14 1 of the second fluid passage 14 (FIG. 2B).
- the tip stopper 5 is provided at the tip of the catheter body 1. Near the distal end of the catheter body 1, an inlet 15 2 of the urinary passage 15 and an outlet 11 1 of the perfusion passage 11 are provided as best shown in FIGS. 3 and 2 (D).
- the first valve 3 for placing in the bladder and the second valve 4 for compressing the prostate gland are connected to the one-way valve 2 3 1 of the inlet 23 of the first fluid passage 13 and the second fluid passage 14. Fluids (for example, distilled water, physiological saline, etc.) are respectively injected from one-way valve 24 1 of extraction port 24.
- FIG. 4 shows a state in which the first balloon 3 and the second balloon 4 are each fully inflated (maximum volumes of 30 cc and 3 cc, respectively). It is preferable that the first balloon 3 expands in a substantially spherical shape and the second balloon 4 expands in a substantially cylindrical shape. This shape is suitable for compression of the prostate and even compression of the prostate in addition to hemostasis.
- the thickness of both ends of the second balloon 4 is made smaller than the thickness of the middle portion (FIG. 5), or It is preferable to provide a plurality of (three in the example shown) outlets 141 of the second fluid passage 14 communicating with the pin 4 in the longitudinal direction of the catheter body 1 (FIG. 4).
- the first balloon 3 is inflated, and the distal end of the catheter body 1 is placed in the bladder so that the catheter body 1 does not fall out of the bladder 200.
- the second balloon 4 is inflated to press the heated prostate tissue 310 from inside.
- the second balloon 4 evenly compresses the prostate tissue after heating, expands the area of atrophy, and suppresses expansion and restoration.
- the catheter for treating benign prostatic hyperplasia of the present invention is not only used for treating benign prostatic hyperplasia, It can also be applied to the treatment of urological diseases.
