Abstract

The invention relates to the technical field of medical instruments, in particular to an innovative disposable catheter used for urethrostenosis soft expansion, especially urethrostenosis and bladder neck obstruction after continuous expansion treatment. A posterior urethra or a bladder neck can be expanded to 28F-40F by utilizing a fixing balloon and a highly expandable balloon in a soft expansion mode, a better long-term curative effect is achieved, urethrostenosis recurrence is effectively prevented, the balloon is radially expanded on a ureter wall, each part is uniformly stressed, bleeding is less, and the normal urethra is not obviously damaged; the disposable urethra balloon dilatation catheter can be fixed in the urethra by the aid of the fixing balloon for cases of which the dilatation time needs to be prolonged, accordingly, the disposable urethra balloon dilatation catheter can be effectively prevented from slipping off, the success rate of operations can be increased, the disposable urethra balloon dilatation catheter can be used for continuously dilating posterior urethra or bladder necks for 24-72 h, and the disposable urethra balloon dilatation catheter has good effects on intractable urethra scars.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a disposable urethral balloon dilation catheter. Background technique [0002] The incidence of urethral stricture is relatively high, and it is common in prostate surgery and urethral trauma. Urethral obstruction can be treated with internal urethrotomy or transurethral bladder neck resection, but the recurrence rate of obstruction after operation is 20%-40%. Although the regular use of 10F-26F rigid metal rods for urethral dilation can partially prevent the recurrence of urethral strictures, but there are many disadvantages: First, the shape of the metal dilation rod is thin at the front and thick at the back, but the bladder neck needs to be dilated to 28F- 40F, the metal dilation rod cannot be realized; second, the dilation time of the existing urethral dilation device for the narrow segment can only last 5-20 minutes, and cannot achieve continuous dilation for 24-72...
