Description

Prostate stroma nodule takes out apparatus

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a prostate stroma nodule taking-out instrument.

Background

Benign prostatic hyperplasia is a common pathological change occurring in the prostate of middle-aged and elderly men and is also a major cause of lower urinary tract symptoms such as frequent urination, urgent urination, progressive dysuria and acute urinary retention. Even serious patients can induce urinary calculus, renal failure and cardiovascular and cerebrovascular diseases.

Early-stage asymptomatic benign prostatic hyperplasia patients only need clinical observation for waiting or medical drug treatment, but most patients progress to moderate and severe lower urinary tract symptoms over time, and finally need clinical surgical treatment to eliminate the symptoms. Transurethral laser enucleation of prostate is the main operation of benign prostatic hyperplasia surgery at present, and under the urethroscope, the hyperplasia prostate is pushed into the bladder after being excised by laser, then is separated into the schistose tissue through the pulverizator, and then is sucked out by negative pressure.

When benign prostate hyperplasia changes, there are first multiple central fibro-muscular nodules, i.e., stromal hyperplasia, in the area of the submucosal gland of the prostatic urethra, and then glandular epithelial hyperplasia. The pathology can be divided into glandular nodules and stromal nodules, which only form stromal nodules if they occur in the glandless zone. In the process of crushing the prostatic hyperplasia tissues, the glandular nodules are easy to crush and suck due to the soft texture of the glandular nodules, while the stroma nodules are hard in texture, and the surface of the glandular nodules is smooth and is not easy to grab and crush by the crusher, so that the operation time can be prolonged, and the probability of accidentally injuring the bladder wall by the crusher is increased. The matrix nodules are finally crushed and taken out through repeated suction and scraping of the prostate tissue disruptor, and the defects that the time consumption is long, and doctors with insufficient experience easily suck and scrape the bladder wall to damage the bladder wall to cause bleeding are overcome.

Therefore, how to safely and rapidly remove the prostatic stromal nodules becomes a technical problem to be solved by those skilled in the art.
