All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-7, in accordance with the present invention, there is provided a bladder irrigation device for urology, comprising:
a catheter 1 having a one-way irrigation channel and a one-way reflux channel;
the drive assembly is connected to one end of the catheter 1, the one-way flushing channel guides flow in the direction away from the drive assembly, and the one-way backflow channel guides flow in the direction close to the drive assembly;
the drive assembly includes:
a flushing cylinder 2 with a flushing cavity and a backflow cavity is formed inside, the flushing cavity is communicated with the one-way flushing channel, and the backflow cavity is communicated with the one-way backflow channel;
two pistons 3 which are respectively arranged in the flushing cavity and the backflow cavity and can synchronously move;
a threaded rod 4 which can move along the axial direction of the washing barrel 2 and is fixedly connected with the piston 3;

From the above and in conjunction with fig. 8-11, it can be seen that:
taking the example where the N teeth 62 are all extended radially to the second position, the left incomplete gear 6 performs counterclockwise rotation, and the right incomplete gear 6 performs clockwise rotation.
In fig. 8, the left incomplete gear 6 is counterclockwise to a state of just disengaging from the threaded sleeve 5, and the right incomplete gear 6 is clockwise to a state of just engaging with the threaded sleeve 5;
in fig. 9, the two incomplete gears 6 are shown in a state formed after the rotation is continued in the position shown in fig. 8; specifically, in the state shown in fig. 9, only the right incomplete gear 6 is meshed with the threaded sleeve 5, whereby the threaded sleeve 5 is rotated counterclockwise based on the driving of the right incomplete gear 6;
in fig. 10, the left incomplete gear 6 is counterclockwise to a state of being just engaged with the threaded sleeve 5, and the right incomplete gear 6 is clockwise to a state of being just disengaged from the threaded sleeve 5;
in fig. 11, the two incomplete gears 6 are shown in a state formed after the rotation is continued in the position shown in fig. 10; specifically, in the state shown in fig. 11, only the left incomplete gear 6 meshes with the threaded sleeve 5, thereby causing the threaded sleeve 5 to rotate clockwise based on the driving of the left incomplete gear 6.
In summary, in the variation of fig. 8-9-10, the threaded sleeve 5 is always kept rotating counterclockwise; in the change process of fig. 10-11-8, the threaded sleeve 5 always keeps rotating clockwise, and the rotation of the threaded sleeve 5 in different directions forms screwing in different directions with the threaded rod 4, so that the threaded rod 4 can be effectively driven to reciprocate. Specifically, the driving directions of the two incomplete gears 6 are not changed, so that the reciprocating movement of the integral threaded rod 4 and the piston 3 can be effectively realized based on the continuous unidirectional driving of the electric device in the case of the motor driving.

based on the position shown in fig. 5, the stopper disk 65 is rotated clockwise so that the entire incomplete gear 6 is changed to the state shown in fig. 6. When the limiting disk 65 is rotated to the position shown in fig. 6, part of the teeth 62 cooperate with the limiting projections so that the part of the teeth 62 are pushed out to the second position radially protruding, and the remaining other teeth 62 remain in the first position.
Based on the position shown in fig. 6, the stopper disk 65 is further rotated clockwise, so that the entire incomplete gear 6 is changed to the state shown in fig. 4. When the limiting disc 65 is rotated to the position shown in fig. 4, all the teeth 62 are engaged with the limiting projections, whereby complete extension of the teeth 62 in the partial gear 6 is achieved.
The length of the meshing arc between the incomplete gear 6 and the threaded sleeve 5 is different depending on the number of projecting teeth 62, and the adjustment of the reciprocating distance between the threaded rod 4 and the piston 3 is effectively achieved.
