[0104] A housing 31 is detachably connected to the connecting cylinder 11.

[0105] A gear structure 32 is engaged with the rack 212.

[0106] A step-by-step rotation structure 33 is connected to the gear structure 32.

[0107] The step-by-step rotation structure 33 drives the gear structure 32 to rotate step by step, thereby driving the sleeve 21 and the guide wire to move step by step.

[0108] Specifically, the housing 31 is detachably connected to the connecting cylinder 11, and the housing 31 is fixed relative to the connecting cylinder 11. The gear structure 32 is engaged with the rack 212, and the rack 212 is moved by the rotation of the gear structure 32, thereby realizing the movement of the sleeve 21 relative to the connecting cylinder 11. The step-by-step rotation structure 33 can drive the gear structure 32 to rotate step by step, thereby driving the sleeve 21 to move step by step relative to the connecting cylinder 11, and realizing the step-by-step movement of the guide wire. The step-by-step rotation structure 33 is located on the side of the connecting cylinder 11 away from the branch cylinder 12 and faces the ureteroscope 40.

[0109] In a preferred implementation of the embodiment of the present application, as shown in Figure 9 and Figure 10 The step-by-step rotation structure 33 comprises:

[0110] A ring structure 331 is arranged in the housing 31.

[0111] A pressing cap 332 is located in the ring structure 331.

[0112] A turntable 333 is located in the ring structure 331.

[0113] A resilient member 334 is located between the turntable 333 and the housing 31.

[0114] The ring structure 331 is formed with a plurality of first guide columns 3311 and a plurality of second guide columns 3312, the first guide columns 3311 and the second guide columns 3312 are staggered arranged; along the radial direction of the ring structure 331, the thickness of the first guide column 3311 is smaller than the thickness of the second guide column 3312; the end surface of the first guide column 3311 and the end surface of the adjacent second guide column 3312 form a continuous first inclined end surface 3313; the side wall end surface of the pressing cover 332 forms a jagged end surface 3321; the side wall of the pressing cover 332 is formed with a plurality of first protrusions 3322, the first protrusions 3322 are located between two adjacent second guide columns 3312, and there is a gap between the first protrusions 3322 and the first guide column 3311; the side wall of the rotating disc 333 is formed with a plurality of second protrusions 3331, the end surface of the second protrusions 3331 forms a second inclined end surface 3332, the inclined direction of the second inclined end surface 3332 is the same as the inclined direction of the first inclined end surface 3313; the second inclined end surface 3332 and the jagged end surface 3321, the vertex of the jagged end surface 3321 and the vertex of the second inclined end surface 3332 are staggered.

[0115] Specifically, as shown in Figure 15 and Figure 16 The ring structure 331 is in the shape of a circular ring, the pressing cover 332 is located in the ring structure 331, the pressing cover 332 can be pressed and moved along the axial direction of the ring structure 331 (or the pressing cover 332), the pressing cover 332 is towards the ureteral flexible scope 40, when holding the ureteral flexible scope 40 with one hand, the ring finger or the little finger can press the pressing cover 332. Figure 18 and Figure 19As shown, the rotating disc 333 is located in the ring structure 331 and rotates relative to the ring structure 331. When the pressing cap 332 is pressed, the pressing cap 332 contacts and drives the rotating disc 333 to move, thereby compressing the elastic member 334. The number of the first guide posts 3311 is the same as the number of the second guide posts 3312. The end surface of the first guide post 3311 is an inclined end surface, and the end surface of the second guide post 3312 is an inclined end surface. The first guide post 3311 and the second guide post 3312 form a guide post combination, and the inclined end surfaces of the two are connected together to form a continuous first inclined end surface 3313, for example, the inclined end surfaces of the two can be coplanar. The elastic member 334 provides an elastic force for the rotating disc 333 to move towards the pressing cap 332. Under the action of the elastic member 334, the second inclined end surface 3332 of the second protrusion 3331 contacts the first inclined end surface 3313 and is located at the corresponding position of the first guide post 3311. When the pressing cap 332 is pressed, the sawtooth end surface 3321 contacts the second inclined end surface 3332 and separates the second inclined end surface 3332 from the first inclined end surface 3313. When the sawtooth end surface 3321 moves to the position of the adjacent first inclined end surface 3313, the second inclined end surface 3332 slides along the adjacent first inclined end surface 3313 under the action of the elastic member 334 and drives the rotating disc 333 to rotate. After the pressing cap 332 is released, the second inclined end surface 3332 slides along the adjacent first inclined end surface 3313 to the corresponding position of the first guide post 3311 in the adjacent first inclined end surface 3313. Each time the pressing cap 332 is pressed, the rotating disc 333 rotates by a preset angle, and the sleeve 21 moves by a preset distance. The preset distance can be 0.5mm-2mm, and the total movement distance of the sleeve 21 can be 5mm-20mm. The preset angle is related to the number of the first guide posts 3311 (or the second guide posts 3312), and the preset angle is the central angle corresponding to one guide post combination. Increasing the number of the first guide posts 3311 (or the second guide posts 3312) can reduce the angle of single rotation of the rotating disc 333; reducing the number of the first guide posts 3311 (or the second guide posts 3312) can increase the angle of single rotation of the rotating disc 333.

[0116] When the pressing cap 332 is pressed, the first protrusion 3322 is limited by the adjacent two second guide posts 3312 and moves in the axial direction of the pressing cap 332. The elastic member 334 can be a spring. The elastic member 334 has a preset elastic deformation amount. When the preset elastic deformation amount is reached, the elastic member 334 cannot continue to deform, and the pressing range of the pressing cap 332 is limited by the preset elastic deformation amount of the elastic member 334 and cannot continue to be pressed. Figure 12 and Figure 17As shown, the vertex of the jagged end face 3321 is staggered with the center of the first protrusion 3322, and the vertex of the jagged end face 3321 is flanked by a first inclined face 3323 and a second inclined face 3324, respectively. The first inclined face 3323 is substantially parallel to the first inclined end face 3313 (or the second inclined end face 3332), and the second inclined face 3324 is substantially symmetrically arranged with the first inclined face 3323. Figure 14 and Figure 15 As shown, the first protrusion 3322 is limited by the second guide column 3312, and the pressing cap 332 cannot rotate. The second inclined end face 3332 forms partial contact with the first inclined face 3323 (as shown in Figure 13 ), and the adjacent second guide column 3312 limits the second protrusion 3331, and the rotating disc 333 cannot rotate. When the first inclined face 3323 moves to the adjacent first inclined end face 3313, the first inclined face 3323 is flush with the adjacent first inclined end face 3313, the second protrusion 3331 is out of the limitation of the adjacent second guide column 3312, the second inclined end face 3332 slides along the adjacent first inclined end face 3313, and contacts with the adjacent second inclined face 3324, until the second inclined end face 3332 forms partial contact with the adjacent first inclined face 3323 after the pressing cap 332 is loosened.
