[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Embodiment 1:

[0027] Reference Figure 1-5A disposable ureteral dilatation balloon catheter comprises a catheter body 1, to which a tube orifice 2 is connected, and further comprises: an insertion head 3, fixedly connected to one end of the catheter body 1 away from the tube orifice 2; a plurality of side openings 301, all of which are arranged on the insertion head 3; an expansion balloon 4, fixedly connected in the insertion head 3, the expansion balloon 4 being connected to the catheter body 1; a plurality of liquid outlets 402, all of which are arranged on the expansion balloon 4, the liquid outlets 402 being located on the side openings 301, the expansion balloon 4 being provided with a plurality of protrusions 401, the protrusions 401 matching the side openings 301, the liquid outlets 402 being located on the protrusions 401, the insertion head 3 being provided with a head opening 302 on part of the side openings 301, and the insertion head 3 being provided with a rounded corner on one end away from the catheter body 1.

[0028] When the device is in use, the tube mouth 2 needs to be connected to a medical device containing a lubricant, and the medical pump is started to allow liquid to slowly enter the catheter body 1. The liquid is finally slowly discharged through the liquid outlet 402, and then the insertion head 3 is inserted into the urethra. The lubricant is used to reduce the pain caused by the insertion. At this time, it is necessary to cooperate with X-rays to facilitate the location of the stone in the urethra. When the appropriate position is reached, that is, when the insertion head 3 is close to the stone, the power of the medical pump can be increased to increase the amount of liquid outflow, and then a little force is applied, and then backed off, and the stone is supported by the insertion head 3 to move the stone slightly. Repeat this several times until the stone is loosened, and the insertion head 3 can be pulled out.

[0029] When the medical pump increases the liquid flow, the protrusion 401 will expand under pressure, and then shrink from the initial state in the side opening 301 to slightly leak out of the side opening 301, contacting the urethra, expanding the urethra, and facilitating the loosening of stones. At the same time, it will increase stability and avoid excessive displacement and urethral damage.

[0030] Embodiment 2:

[0031] Reference Figure 1-5 The disposable ureteral dilatation balloon catheter is basically the same as that of Example 1, and furthermore, the dilatation balloon 4 is provided with a head dilatation end 403, and the head dilatation end 403 is connected with a puncture head 404, and the puncture head 404 is used to puncture stones.

[0032] When encountering stones, by increasing the flow of the medical pump, the head expansion end 403 will extend from the insertion head 3 from the initial position, and then contact the stones, so as to break some weak stones and facilitate their discharge.

[0033] It should be noted that before use, it is necessary to observe whether the puncture head 404 leaks out, that is, whether it extends out of the insertion head 3, to avoid extension causing secondary damage to the urethra.

[0034] The utility model can continuously discharge lubricating liquid through the arrangement of the liquid outlet 402 and the side opening 301, thereby reducing stimulation to the urethra during movement and facilitating the progress of the operation. Meanwhile, through the arrangement of the puncture head 404, the calculi in the urethra can be effectively punctured to loosen or break them, thereby facilitating the discharge of the calculi.

[0035] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
