Further, the catheter outer wall is provided with the gasbag, catheter afterbody lateral wall is provided with the water filling port, the water filling port is provided with the water injection hard valve, the water injection hard valve is through water injection tubule and gasbag intercommunication.

Further, the included angle between the guiding section and the central axis of the catheter is 10-20 degrees.

Further, a hard shell protecting sleeve is arranged on the outer wall of the joint of the water injection port and the catheter.

Further, the catheter head is configured as a hemisphere.

Further, the tail of the catheter is provided with an external thread interface, and the Y-shaped connecting part is provided with an internal thread interface matched with the external thread interface.

Compared with the prior art, the utility model has the beneficial effects that:

the Y-shaped connecting part with the threaded interface is arranged, a structure capable of realizing the function of directly and detachably connecting the branch ports is provided, and the technical scheme for solving the problem that the guide wire is difficult to withdraw due to the fact that the connecting part cannot be integrally dismantled is provided, so that the risk of urinary tract infection of a patient is reduced, the pain of the patient is relieved, the operation difficulty of medical staff is reduced, the treatment recovery time is shortened, and more medical resources are directly saved. Meanwhile, the front end of the catheter can smoothly enter the pubic antecedent curve and the pubic hypocedent curve in the male urethra through the guide section, and the catheter is guided to integrally pass through, so that the passing capacity of the catheter is improved, and the safety of an operation is further improved.
