Description

Prostate ligation procedure system

This application claims the benefit of priority based on Korean Patent Application No. 10-2021-0114934 dated August 30, 2021, and all contents disclosed in the literature of the Korean patent application are included as part of this specification.

The present invention relates to a prostate ligation (UROLIFT) procedure system with improved accuracy and convenience of the procedure.

In general, benign prostatic hyperplasia is a symptom in which the prostate is abnormally enlarged and blocks the prostatic urethra through which urine comes out of the lower part of the bladder, causing urethral obstruction and inability to discharge urine. When prostate enlargement occurs, symptoms such as frequent urination, nocturia, urgency, small urination, and residual urine appear, causing considerable inconvenience in daily life.

Treatment of benign prostatic hyperplasia is largely divided into non-surgical treatment and surgical treatment. Non-surgical treatment includes wait-and-see therapy with regular examinations and drug treatment with medications if the patient's symptoms are mild. It is known that drug treatment can improve the symptoms of benign prostatic hyperplasia to some extent. However, drug treatment has the disadvantage that symptoms recur when administration is stopped, and side effects may occur.

The most effective treatment for an enlarged prostate is surgery. Conventional surgical methods such as transurethral prostatectomy using a urethral endoscope are known for BPH surgery. Recently, less invasive methods such as prostate vaporization using a high-power laser and holmium laser prostatectomy have also been performed.

In addition, recently, a procedure method of securing the urethra by ligating the enlarged prostate by passing a medical ligature through the prostate using a UROLIFT procedure device 300 as shown in FIG. 1 has also been implemented. The detailed description of the prostate ligation (UROLIFT) procedure is as follows.

When prostatic hyperplasia occurs, as shown in (a) of FIG. 2, a pair of prostates (A, B) enlarge on both sides of the urethra and block the urethra (C). As shown in (b) of FIG. 2, the operator inserts the sheath 310 into the urethra, and as shown in (c) of FIG. 2, the medical ligature 11 is inserted into the prostate (A, B). After penetrating, as shown in (d) of FIG. 2, the first implant 20 is operated on the upper part of the left prostate (A), and as shown in (e) of FIG. 2, the right prostate (B) A second implant 20a is placed on the top.

And, as shown in (f) of FIG. 2, the third implant 20b and the fourth implant 20c are applied to the lower part of the left prostate A and the right prostate B, respectively. At this time, each of the

implants

20, 20a, 20b, and 20c includes an outer implant 21 disposed outside the prostates A and B and an inner implant 23 disposed on the urethra side by a ligation thread 25. Connected, the internal implant 23 by the length of the ligature 25 presses the prostate (A, B) outward to open the urethra.

When the sheath 310 of the prostate ligation apparatus 300 is bent in order to pressurize the prostate, the angle confirmation member 270 performs a function of allowing the operator to accurately grasp the bending angle. That is, according to the conventional treatment method, since such an angle checking means does not exist, it is difficult to grasp an accurate bending angle because the surgeon has to rely on the senses. Also, for this reason, it was difficult to perform an accurate operation.

As shown in FIG. 10, the angle checking member 270 may be in the form of a normal protractor fixed to the arm 210 adjacent to the ring-shaped penis accommodating member, but is not limited thereto, and can determine the bending angle. Any type of mechanism may be employed as the angle checking member 270 .

For example, the angle checking member 270 may be in the form of a protractor made of a transparent material, or may be in the form of fixing a plurality of rods to the arm 210 in the form of fan blades according to a predetermined angle.

In one embodiment of the present invention, as the prostate ligation procedure device 300, a known procedure device used for prostate ligation (UROLIFT) can be used without limitation, so a detailed description of the device configuration will be omitted. Regarding the configuration of the device, reference may be made to Korean Patent Registration No. 10-2170400.
