Description

Visual prostate expands and splits ware

Technical Field

The utility model relates to a medical instrument especially relates to a visual prostate expands and splits ware.

Background

The obstructive chronic prostatitis is a new concept recently proposed, is a disease which mainly shows that the chronic prostatitis is taken as the first symptom and then the bladder outlet obstruction is shown, and the chronic prostatitis is considered to be mainly caused by the long-term inflammation stimulation of glands to increase the local urethra, the prostate envelope and the parenchymal blood flow, the stimulation of adrenoreceptors to cause the sensation allergy of the bladder, the frequent micturition and the urgent micturition, and the threshold of the early sense of the filling of the bladder in the urodynamic examination is reduced. Long-term hyperemia causes hyperplasia of fiber tissues of the urethra and the bladder neck of the prostate part, and a normal funnel-shaped structure of the bladder neck disappears and is replaced by a dam-like structure, so that bladder outlet obstruction can be formed, urine is not smoothly flowed out, the risk of urinary infection can be increased due to urine accumulation, urinary infection can further aggravate inflammatory hyperemia and edema of the prostate part, and fibrosis is aggravated to form a vicious circle. A compensatory increase in detrusor contractility can occur in the early stage of bladder outlet obstruction, and detrusor contractility impairment can occur after the compensation is lost.

Patients with obstructive chronic prostatitis and bladder neck sclerosis often have no effect on drug treatment and show serious bladder outlet symptoms. For stubborn patients, surgical operation is often needed for treatment, and the main operation modes comprise transurethral cystocervical hump type incision, prostatectomy, transurethral prostatectomy, prostatic posterior cruciate dissection, cystocervuloplasty and the like, which have certain effects on improving urination, but the long-term effect is not ideal. At present, transurethral resection, laser enucleation and the like are used for treating prostatic hyperplasia through operations, but the operations have the problems of large trauma, influence on sexual function by retrograde ejaculation and the like. The balloon dilation can rupture the prostate gland capsule, thereby opening the gland and reducing the urethral resistance to relieve patient obstruction. In 2009, zhangyong et al performed experimental studies on this technique, and confirmed that TUDP (translation into chinese is what we call, and is not meant for balloon dilatation) can effectively dilate the prostatic urethra and the membranous urethra without functional damage to the urethral sphincter, suggesting that TUDP can safely and effectively treat prostatic hyperplasia. However, the existing medical device for performing balloon dilatation has the following defects: the device cannot be used in cooperation with an observation mirror, so that the positioning is complicated and the tube placement is difficult; since the dilating catheter is a flexible tube, it is difficult to insert the dilating catheter into the urethra.
