In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present invention.

[0022] See also Figure 1-6 An embodiment of the present invention is a urethral dilation device for urological surgery, comprising a handheld portion 1 and a probe 4 sliding in the handheld portion 1; a sliding member 3 is also provided on the handheld portion 1, and the probe 4 is urged to extend to the outside of the handheld portion 1 through the sliding member 3; the sliding member 3 comprises a slider 30 and a piston 31 sliding inside the handheld portion 1, and is connected to the piston 31 after passing through the slider 30 through a connecting member 34, so that the slider 30 guides the probe 4 to slide in a directional manner.

[0023] In summary, since the hand-held portion 1 is provided on the outside of the probe 4, the probe 4 is easy to grasp when being taken and used, thereby reducing the problem of inconvenience for medical staff in grasping the probe due to its thinness; in particular, the movement of the probe 4 is controlled by the slider 30, and the slider 30 and the hand-held portion 1 have a large diameter, so when holding the device, it will not slip easily, and after holding the hand-held portion 1, the thumb pushes the slider 30 to move, so that the movement of the probe 4 is stable and controllable, reducing the patient's discomfort.

[0024] Based on this, the device has the following advantages when used: first, the device has a simple structure and is easy to use; second, the setting of the handheld part is convenient for medical staff to hold; third, the moving speed of the probe can be controlled by a slider.

[0025] Furthermore, since one end of the piston 31 is threadably matched with the probe 4 via the first connecting portion 32, the model of the probe 4 can be replaced simply and conveniently.

[0026] Furthermore, since the other end of the piston 31 is connected to the connecting pipe 5 via the second connecting portion 33, the connection and disassembly of the piston and the connecting pipe 5 are simple and convenient, wherein the connecting pipe 5 is also connected to the second connecting portion 33 by threaded fitting.

[0027] In addition, since the first connection portion 32 and the second connection portion 33 are connected and communicated, the probe 4 and the connection tube 5 can be connected and communicated.

[0028] On the basis of the above scheme, since the probe 4 includes a rod body portion 40, and a transition portion 41 is provided at one end of the rod body portion 40; and a spherical surface 43 is provided at one end of the transition portion 41 away from the rod body portion 40, the probe 4 is more convenient to use, and the setting of the spherical surface 43 can reduce the damage to the urethra caused by the probe 4 during the insertion process.

[0029] Furthermore, since the probe 4 is provided with a through hole 42 inside, and the through hole 42 completely penetrates the rod body 40, the transition portion 41 and the spherical surface 43, the external lubricating liquid can be drained into the probe 4 through the connecting tube 5, so when the probe 4 is inserted, the lubricating liquid can lubricate the urethra to further reduce the damage to the urethra caused by the probe 4 when it moves.

[0030] Furthermore, since a groove 2 is provided on the outer circumferential surface of the hand-held portion 1, and the slider 30 is guided by the groove 2 to slide in a directional manner, the probe 4 will not rotate axially when moving, thereby further avoiding the problem of urethral damage caused by the movement of the probe 4.
