Multistage urethral stricture dilatation type drainage tube with balloons

Abstract

The invention provides a multistage urethral stricture dilatation type drainage tube with balloons. The multistage urethral stricture dilatation type drainage tube comprises drainage tubes and a support tube, wherein the drainage tubes include a drainage tube I, a drainage tube II, a drainage tube III and a drainage tube IV; the drainage tube I is internally provided with a channel I; the drainagetube II is attached to a head end balloon, and a channel II and a channel III are arranged inside the drainage tube II; a channel IV, a channel V, a channel VI, a channel VII and a channel VIII are arranged in the drainage tube III; the outer wall of the drainage tube III is sleeved with a balloon I, a balloon II and a balloon III; a channel IX, a channel X, a channel XI, a channel XII and a channel XIII are arranged in the drainage tube IV; a connector I, a connector II, a connector III, a connector IV and a connector V are arranged on the drainage tube IV; the tail end of the support tube is connected with the connector V; and the support tube is inserted into a channel in the connector V and penetrates out of the channel I. By adopting the scheme for urethral stricture dilatation and urination, the stricture dilatation range can be expanded, the replacement frequency of the drainage tube can be reduced, and the disease course can be shortened.

Description

technical field [0001] The invention relates to the field of minimally invasive medical technology and surgical instrument technology, in particular to a multi-stage urethral stricture dilating drainage tube with a balloon, which is a minimally invasive surgical instrument for urethral stricture dilation and urine drainage. Background technique [0002] Urinary catheter is a common medical device in clinical practice. It is inserted into the bladder through the external opening of the urethra to drain urine out of the body. Its main function is to accurately record urine volume, facilitate drainage and flushing, and play an important role in clinical practice. [0003] The catheter materials currently used mainly include silica gel, rubber, EVA, PVC, etc., and its tube body is soft. For patients with diseases such as urethral stricture, benign prostatic hyperplasia, prostatitis, prostate tumor, and urethral injury, the inner diameter, course, and curvature of the urethra cha...

Problems solved by technology

The current conventional method is to dilate the urethra with a metal urethral dilator, which usually expands the urethra multiple times from small to large sizes, and then inserts a thicker catheter for a longer period of support to promote the healing of the injured mucosa. This kind of operation takes a long time, which not only increases the pain of the patient, but also makes it inconvenient to keep the metal urethral dilator during catheterization, and it is still difficult to insert a thick catheter
