Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
The first implementation mode comprises the following steps: with reference to fig. 1-4, the embodiment is described, a urethra dilation kit, comprising a safety guidewire 1, a dilator 2 and a wireless ultrasound probe;
the dilator 2 comprises a tip 21, a body 22 and a grab handle 23, the tip 21, the body 22 and the grab handle 23 are sequentially connected and integrally formed through processing, the through holes 24 sequentially penetrate the dilator,
the safety guide wire 1 is arranged in the through hole 24, the safety guide wire 1 is a hydrophilic guide wire or a zebra guide wire, the hydrophilic guide wire has an ultra-smooth property, and can be used for the first time when a patient with a heavy stenosis degree is treated, and the zebra guide wire can be reused after being sterilized, so that the use cost is reduced; the wireless ultrasonic probe is used for ensuring that the safety guide wire 1 is positioned in the bladder, the wireless ultrasonic probe 3 is connected with a display screen of a smart phone through a wireless signal, the wireless ultrasonic probe is adopted, the size is small, APP can be downloaded through the smart phone to be used, after the safety guide wire enters the bladder, the safety guide wire is pulled at the external orifice of the urethra, and an acoustic image of the activity of the safety guide wire in the bladder can be displayed on the display screen of the smart phone, so that the mode is simple and rapid;
the section diameter of the tip 21 along the body 22 direction is gradually increased and is conical, the front end of the tip is conical, so that the dilator can pass through a narrow urethra, the outer wall of the body 22 is provided with scale marks, medical staff can observe the scale marks conveniently, the length of the body inserted into the urethra can be clearly known, the side wall of the body 22 is provided with a flow hole 25 for urine circulation and discharge, the section diameter of the grab handle 23 is larger than that of the body 22, and the outer wall of the grab handle 23 is provided with an anti-skid bulge, so that the grab handle is convenient for inserting the dilator, and the limiting function can be achieved, and the dilator can be prevented from being completely inserted into the urethra and cannot be taken out due to improper use; preferably, the dilator 2 is made of polyethylene, so that the dilator has rigidity and elasticity, can realize bending and compression resistance, can bend along the physiological bending of the urethra after entering the urethra along the safe guide wire, and compared with the traditional metal dilator, the dilator with rigidity and elasticity obviously reduces the damage probability of the expansion activity to the physiological bending of the urethra, and when passing through the narrow urethra, the dilator with a hollow structure can be deformed and then continuously inserted through the narrow urethra to achieve the purpose of treatment, and the side damage is reduced; the dilator can be F8, F10, F12, F14, F16, F18, F20, F22 and F24, and the dilator with proper size can be selected according to the condition of the patient for treatment.
The operation process is as follows: the method comprises the steps of firstly, inserting a safety guide wire into a bladder from an external urethral orifice, secondly, twitching the safety guide wire back and forth in a small range at the external urethral orifice, checking the lower abdomen by using a wireless ultrasonic probe, and displaying an acoustic image of the safety guide wire on a smart phone display screen, so as to ensure that the safety guide wire enters the bladder through a narrow-section urethra, and thirdly, inserting an expander into the urethra along the safety guide wire to expand the narrow-section urethra.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
