Definitions
- the present invention relates to an enlarged prostate treatment apparatus, and more particularly, to an enlarged prostate treatment apparatus capable of continuously opening the prostatic urethra by ligating the enlarged prostate to the outside of the urethra.
- benign prostatic hyperplasia is a symptom in which the prostate is abnormally enlarged and blocks the prostate urethra from which urine flows from the lower part of the bladder, causing urethral obstruction, which prevents smooth urine discharge.
- the enlarged prostate treatment method shown in FIG. 1 is performed.
- a pair of prostates are enlarged on both sides of the urethra to block the urethra (C) as shown in FIG. 1 (a).
- the operator inserts the cystoscope 10 into the urethra as shown in FIG.
- the first implant 20 is operated on the upper part of the left prostate (A) as shown in (d) of FIG. 1, and on the right side as shown in (e) of FIG.
- the second implant (20a) is operated on the upper part of the prostate (B).
- each of the implants (20, 20a, 20b, 20c) has an external implant (21) disposed on the outside of the prostate (A, B) and an internal implant (23) disposed on the urethra side by a ligator (25).
- the inner implant 23 by the length of the ligator 25 presses the prostate (A, B) to the outside to open the urethra.
- this conventional prostatic hyperplasia treatment method has a limitation in that the area of the prostate tissue that can be compressed using one implant 20 is limited to the size of the inner implant 23 .
- An object of the present invention is to solve the above problems, and to provide an apparatus for treating enlarged prostate, which is arranged in the upper and lower parts of the prostate and can adjust the compression area by a pair of anchors connected to each other by a ligator.
- Another object of the present invention is to provide an enlarged prostate surgery apparatus capable of continuously compressing the prostate according to the size of the prostate for each patient by adjusting the length of the ligature connecting the pair of anchors.
- the above-described object of the present invention can be achieved by a prostatic hyperplasia treatment apparatus.
- the apparatus for treating benign prostatic hyperplasia of the present invention connects a pair of anchors 210 and 220 vertically disposed on the outside of the prostate to press the prostate urethra, and the pair of anchors 210 and 220 to connect the pair of anchors 210 and 220 ) and an anchor assembly 200 having a ligation chamber 230 that continuously presses the prostate tissue to secure the prostate urethra; a sheath 300 inserted into the urethra and accommodating a needle 350 for guiding the anchor assembly 200 to be ligated to the prostate; and a needle manipulator 400 for manipulating the movement of the needle 350 so that the needle 350 is discharged through the end of the sheath 300 .
- a thread winder 500 provided on one side of the needle operation unit 400 to wind the ligation chamber 230 to adjust the strength of the anchor assembly 200 pressing the prostate; It is preferable to include a handle frame part 100 that supports the end of the sheath 300, the needle operation part 400, and the thread winder 500, and is held by the operator.
- the prostatic hyperplasia treatment apparatus has the advantage that the urinary velocity can be further accelerated because the prostate tissue compressed by the ligation chamber and the pair of anchors is continuously connected, compared to the conventional treatment method in which the tissue of the prostate is partially compressed. This may have a greater effect in patients with a long prostate.
- the prostatic hyperplasia treatment apparatus has the advantage that the operator can adjust the strength of compressing the prostate as much as the operator desires by winding the free end of the ligation chamber and adjusting the length of the ligation chamber.
- the treatment method using the prostatic hyperplasia treatment apparatus of the present invention does not require general anesthesia or long operation time, such as other laser treatment or electrical surgery using thermal energy.
- the simple anchor installation method enables fast operation time and local anesthesia, and does not cause side effects such as retrograde ejaculation, erectile dysfunction or hematuria because the prostate tissue is not cut.
- it since it is non-invasive, it has the advantage of being able to receive additional surgery at any time if there is no effect.
