Description

Visual urethra dilator for outpatient service

Technical Field

The utility model relates to a urethra dilatation apparatus, more specifically say, relate to a visual urethra dilator for outpatient service.

Background

Urethral dilation is a common operation in urology, and the traditional dilation method is to adopt a metal dilator for blind dilation, so that the urethral tissue is easy to be damaged and urethral false tract is easy to form due to the fact that the metal dilator is purely felt by hand; visual urethral dilation can reduce such damage and improve dilation success rates.

As shown in fig. 1, a visual urethra dilator (CN202876068U) comprises a fiber visual mirror 1, the end of the fiber visual mirror 1 can be connected to a camera screen (not shown in the figure) of a visualization system, the fiber visual mirror 1 is arranged in a metal sheath 2, the end of the metal sheath 2 is provided with a water outlet 3, water is flushed into the metal sheath 2, and the urethra is cleaned through the water outlet 3.

As shown in fig. 2, a visual electronic mirror urethra dilator (CN108992769A) comprises a display screen 1, a metal mirror pin 4, a balloon 5 and a visual urethroscope 6, which are positioned in a hollow straight pipe and a hollow bent pipe which are connected with each other, and are connected to a dilating head through a camera probe at the head part of the dilator; still be equipped with three way switch on the snap ring device, three way switch connects the bath system, can wash by water in to straight tube 3 and return bend 2, and the space entering of the visual urethroscope of rivers accessible and pipe wall is washed out through the delivery port on the lateral wall of return bend 2 front end, washs the urethra.

However, at present, urethral dilation is mostly performed in outpatient service, so that the device is required to be used conveniently and frequently under the aseptic condition. Therefore, the above two dilators have several drawbacks:

1. the former is not suitable for outpatient operation, and the fiber visual mirror tail end of the former needs to be externally connected with a huge imaging system and is only suitable for operating room conditions.

2. Both of them adopt the mirror pin of metal material, and the urethroscope in the sheath is linked together with the urethra environment because of the existence of the delivery port of round pin front end, therefore in case use back, must disinfect, not only need disinfect the metal mirror pin, but also need disinfect the urethroscope, so cause the disinfection time long and loaded down with trivial details, be unfavorable for the frequent use of outpatient service, in addition repeated disinfection also easily causes the damage of urethroscope.

3. The display screen of the urethroscope in the latter is designed to face the head of the metal mirror pin and can only rotate back and forth by a certain angle, and during actual operation, an operator can usually be in two positions, one is lateral operation, namely lateral operation of a patient, and the other is posterior operation, namely middle position of opening two legs of the patient, so that the display screen needs to face the side or the back to facilitate visual operation of the operator.

4. Both the two are provided with metal mirror pins, the front end of the metal mirror pins is necessarily provided with another transparent material to meet the visibility of the urethroscope, and the combination design of the two different materials is adopted to certainly increase the manufacturing cost and difficulty.
