Description

Transurethral balloon catheter expansion device for ejaculatory duct obstruction

Technical Field

The invention belongs to the technical field of medical appliances, and particularly relates to a transurethral balloon catheter expansion device for ejaculation pipe obstruction.

Background

The ejaculatory duct obstruction belongs to obstruction of the distal testosterone end of the seminal duct, the cause of the obstruction is congenital and acquired, and the obstructive infertility caused by the obstruction accounts for about 1% -5% of male infertility. The main clinical symptoms are ejaculatory pain, hemospermia, scrotum pain, perineum discomfort, chronic pelvic pain, ejaculation hypodynamia, small semen volume and abnormal urethral orifice, and small part of patients can be combined with epididymitis or seminal vesiculitis. However, the traditional transurethral ejaculation tube incision has obvious defects, the operation often needs to use electrotome to climb to electrotome the verruca, the depth and the range of electrotome are needed to be mastered in the operation, and simultaneously, the operation wound surface is observed to have milky white, brown, yellow brown or dark red liquid flowing out or not so as to determine whether to expose the bilateral ejaculation tube, the experience and the operation requirements of an operator are higher, and simultaneously, higher postoperative complications such as postoperative scar formation, urine reflux, seminal fluid rarefaction, hematuria, epididymitis, seminal vasculitis, urinary incontinence or rectal perforation and the like exist. The method brings endless trouble and pain to the patient. And so many complications also place a significant burden on the care effort.

Disclosure of Invention

In order to overcome the defects in the prior art, the invention aims to provide a transurethral balloon catheter expansion device for the obstruction of an ejaculatory duct, which expands the obstruction section of the ejaculatory duct through a balloon catheter, and the method is convenient and reliable. The device can better solve the ejaculation pipe obstruction, is particularly suitable for patients with incomplete ejaculation pipe obstruction and patients with prostatic outer section obstruction, and can open the opening of the ejaculation pipe and then expand the air bag for patients with complete obstruction. The device can maintain normal ejaculation tube opening, so that the occurrence of urine reflux and other complications can be reduced.

In order to achieve the technical purpose, the invention adopts the following technical scheme:

a transurethral balloon catheter distention device for ejaculatory duct obstruction, wherein: including catheter, two expansion pipes, aerating device and display device, be provided with an axially extending's division board in the catheter, two catheterization spaces about the division board separates the catheter inner chamber into, in two expansion pipes all slidable ground inserts the catheter, and each occupy a catheterization space, the top of expansion pipe is provided with the probe, the probe passes through external display device of connecting wire, cavity in the expansion pipe, expansion pipe front end outside cover has a plurality of gasbag, and these gasbags evenly lay along the expansion pipe axial, every gasbag all communicates with the inner chamber of expansion pipe, the expansion pipe rear end is connected with aerating device, hug closely the expansion pipe wall when the gasbag is not inflated, swell after the inflation.

In order to optimize the technical scheme, the specific measures adopted further comprise:

the front half part of the expansion pipe is positioned in the catheter, the rear half part of the expansion pipe extends out of the rear end of the catheter, the expansion device further comprises a hub, and the rear half part of the expansion pipe is received in the hub.

The connecting wire is positioned in the inner cavity of the expansion tube, and the rear end of the connecting wire penetrates out of the expansion tube and is connected with the display device.

The length of the expansion pipe section sleeved with the air bag is 2cm to 2.5cm.

The inflation device is a hand-pressed air bag.

The probe is a high-light-transmittance objective lens, the connecting wire is a visual optical fiber, and the display device is a display screen.

The transurethral balloon catheter expansion device for the ejaculation pipe obstruction combines the expansion pipes with the catheter, and can be used as an outer sheath of the expansion pipes because the diameter of the catheter is larger, the two expansion pipes are delivered to the inlet position of the ejaculation pipe, and then the expansion pipes are respectively operated to enter the ejaculation pipe. The use of multiple small balloons allows for more uniform expansion of the ejaculatory duct than with only one large balloon.
