As the boy ages, the prostate enlarges, compressing the posterior urethra and bladder neck and causing dysuria. Is a frequent condition. The symptoms are
Urinary difficulty including urinary frequency and urinary retention is common, cystitis, bladder dilation, trabeculoplasty, bladder stones, bladder diverticula, hematuria, micronephrosis,

道狭窄の有無を知り得る。The anatomical findings are that multiple fibroadenomatous nodules usually form in the so-called inner gland of the subepithelium of the urethra, which compresses the normal prostate tissue, the outer gland, into the prostate capsule. The result is a so-called surgical capsule. The diagnosis can be confirmed directly by a urethroscope, and the presence of residual urine or urethral stricture can be known by inserting a catheter into the urethra.

要なものである。There are medical treatment and surgical treatment for the treatment of benign prostatic hyperplasia, and as the medical treatment, a method mainly consisting of medication is mainly used, and as the surgical treatment, prostatectomy (cutting) and resection. [Hereinafter, simply referred to as "prostatectomy"] is the main one.

する。In the prostatectomy, a resectoscope (Resectoscop) that integrally combines a urethral endoscope and an electric scalpel is used.
There is a transurethral procedure using e). The transurethral type is
Minimal surgical invasion but requires specialized equipment and techniques.

固電流を受ける差し込み部が取り付けられている。The Resectoscope is an ablation endoscope, which is an optical machine for ablating tissue such as prostate and bladder tumor. Its structure is attached to the endoscope portion and the tip. A body capable of actuating the cutting loop as an electric scalpel at hand is covered with a plastic outer tube, and a light source and an insertion portion for receiving cutting current and coagulation current are attached.

The method of use is such that while perfusate is flowed to the target tissue, the tissue is confirmed under an endoscope, and the tissue is excised or coagulated by scraping by operating an excision loop. The working part of the loop is Nesbi

療の主流たりえない。DISCLOSURE OF INVENTION Problems to be Solved by the Invention However, although some effective drugs have been developed, the drug therapy as a medical treatment method is effective only for the duration of the drug's effect, and it becomes an immune state due to habitual addiction. There is also the problem of so-called drug dependence, in which the efficacy of the drug gradually weakens, and at present, the treatment of benign prostatic hyperplasia cannot be the mainstream.

一体構造のため、破棄せざるを得ず、不経済であった。Further, when the above-mentioned conventional resectoscope is used, a sophisticated technique for directly performing painful resection surgery by directly contacting the affected prostate with an endoscope is required. At that time, blood scattered in the perfusate is required. If the endoscope is clouded early due to the adherence of urine or endocrine fluid and the image of the endoscope becomes poor and other parts can withstand sufficient use, the equipment is inseparable, so it is discarded. It was unavoidable and uneconomical.

目を浴び、実用化されている。From the above viewpoints, in terms of the simplicity of non-contact surgery, a treatment for rapidly sinter-coagulating an affected area by laser irradiation without causing bleeding and pain, and exfoliating and excision in a scab like shape has been attracting attention and put to practical use. Has been done.

道、ｄは尿道球膜である。There is a so-called laser scalpel as a so-called conventional treatment tool by laser irradiation. As shown in FIG. 6, the laser scalpel has a reflecting mirror 2 attached to the distal end of the urethral transluminal tube 1, and the urethral transluminal tube 1 is attached. The tip 3a of the glass fiber 3 for laser light guiding inserted in the above is faced to the reflecting mirror 2, and the laser light α emitted from the tip 3a is reflected by the reflecting mirror 2 to irradiate the affected area. In the figure, a is the bladder, b is the prostate, c is the urethra, and d is the urethral bulb membrane.

こともたびたびあった。However, since the treatment tool does not have an endoscope and therefore the radiation treatment is performed with a general guide from the outside, the irradiation treatment site cannot be visually recognized from the outside, and radiography or ultrasonic waves can be used. After the fact, there was no other method than vaguely confirming it, and it was often the case that the normal prostate gland other than the affected area was also sintered and solidified.

う。Further, as shown in FIG. 6, the structure is such that the urethral tube 1, the reflecting mirror 2, the laser guiding glass fiber 3, and the irrigation fluid supply / drain tube (not shown) built in the urethral tube 1 cannot be separated. Since it is integrally formed, like the above-mentioned resectoscope, the fogging of the reflecting mirror 2 adversely affects the focusing of the laser light and causes diffuse reflection, so that the life of the reflecting mirror 2 with the shortest life is one time. Depends on and expensive 1
Inevitably it becomes a one-time disposable item, and the product price exceeds the cost of one treatment, which reduces the practical value.

Especially the reflector can be exchanged,
It is intended to provide a Prostascope with a Matioli bridge whose surface can be polished.
