Problems solved by technology

[0003] However, the above-mentioned means have considerable limitations. The current mainstream urethral dilation can only rely on the operator's touch when probing into the urethra through the urethral dilator. The risk of aggravating the injury is extremely high, and the insertion of the guide wire through cystoscopy needs to be performed in the operating room or a special venue, and the cystoscope cannot safely and gradually expand the urethral stricture, posing a safety hazard

Embodiment 1

[0024] see Figure 1-6 , by holding the handle 6 and inserting the optical fiber rod 7 into the urethral dilator 1, the curved rod 72 of the optical fiber rod 7 will bend along the bend of the urethral dilator 1 into the same arc, and when fully inserted, the position of the lens 8 is just at the At the mirror hole 2, at this time, the polygonal block 42 is inserted into the polygonal hole 32, and the ferrule 31 is controlled to rotate through the wrench 33, and the position of the polygonal hole 32 is adjusted to match the polygonal block 42, and the two are clamped together. 5 Connect with an external monitor, insert the urethral dilator 1 into the patient's urethra, the curved part of the urethral dilator 1 is thin in the front and thick in the back, which is convenient for slowly expanding the urethral stricture, and the picture transmitted by the lens 8 can be observed The internal condition of the urethra is convenient for doctors to judge.

Embodiment 2

[0026] see Figure 7-9 , by holding the handle 6 and inserting the optical fiber rod 7 into the urethral dilator 1, the curved rod 72 of the optical fiber rod 7 will bend along the bend of the urethral dilator 1 into the same arc, and when fully inserted, the position of the lens 8 is just at the At the mirror hole 2, at this time, the locking block 34 on the outer surface of the ferrule 31 is engaged with the locking groove 43 on one side of the connecting pipe 9, so that the two are fixed together.

[0027] The outer circle size of the urethral dilator 1 is divided into several models, and the inner size is always in close contact with the outer circle of the optical fiber rod 7. When exploring the urethra, the optical fiber rod 7 is inserted into the urethral dilator 1 with different outer circle sizes. , During operation, different types of urethral dilators 1 are selected for insertion and observation in order from thin to thick, so as to ensure the safety of use and not ...

Abstract

The invention discloses a portable visualized device for urethral dilatation and assistance of urethral catheterization. The device comprises a urethral dilator, wherein the urethral dilator comprisesa straight part and a curved part, the urethral dilator is of a hollow structure, and an optical fiber rod is inserted into the urethral dilator in a connected mode; optical fiber is arranged in theoptical fiber rod, the optical fiber rod is composed of a straight rod body and a curved rod body, and a lens hole is formed in the head end of the curved part of the urethral dilator; a lens is arranged at the head part of the curved rod body, the position and size of the lens is matched with the position and size of the lens hole, and the curved rod body is made from a plastic material; the outer side surface of the optical fiber rod fits the inner side surface of the urethral dilator closely, one end of the optical fiber rod extends out of the urethral dilator, and is fixedly connected witha connection tube, and an optical fiber interface is arranged at one end of the outer side surface of the connection tube; and the optical fiber interface is electrically connected with an external monitor. Through the portable visualized device for urethral dilatation and assistance of urethral catheterization, the interior of urethra can be observed, and it is convenient for doctors to operateaccording to internal conditions, so that the safety of operation is improved greatly.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a portable visualized urethral dilation auxiliary catheterization device. Background technique [0002] With the intensification of population aging, the incidence of some aging diseases such as benign prostatic hyperplasia is getting higher and higher, and some congenital stenosis, trauma and iatrogenic injury cause urethral stenosis. The general treatment is to try to indwell the catheter. If the indwelling tube is unsuccessful, it can be treated symptomatically when the cause of the patient is relatively simple. If the urethra is slightly narrowed, urethral dilatation and prostatic hyperplasia can be performed by cystoscopy, and the catheter is placed along the guide wire after the guide wire is inserted. [0003] However, the above-mentioned methods have considerable limitations. The current mainstream urethral dilation can only rely on the operator's touch when pr...
