[0025] As Figures 1 to 5As shown, the self-locking pressing structure 10 of the embodiment is used on the flush suction ablation electrode device 100 to control flushing or suction by pressing the self-locking pressing structure 10. The self-locking pressing structure 10 comprises a button 1 protruding outside the shell of the flush suction ablation electrode device 100. The button 1 is provided with a sliding block 2 slidingly arranged in a limiting frame 3. The user presses the button 1 to drive the sliding block 2 to slide in the limiting frame 3. The sliding block 2 divides the limiting frame 3 into a first area 31 for passing a catheter 5 and a second area 32 provided with an elastic member 4 pressing against the sliding block 2. The elastic member 4 has a biasing force on the sliding block 2. When the button 1 is not forced, the biasing force of the elastic member 4 makes the sliding block 2 clamp the catheter in the first area 31, so that the fluid cannot flow through the catheter, and the catheter is cut off. After the button 1 is pressed, the sliding block 2 slides to the second area 32, the elastic member 4 is compressed, and the catheter 5 is released, so that the fluid can flow through the catheter. The elastic member 4 of the embodiment is a spring. The sliding block 2 is provided with a guide groove 6, and the guide groove 6 is provided with a first side wall 61 and a second side wall 62 on both sides. The first side wall 61 has a recessed part 611, and the second side wall 62 has a protruding part 621. The protruding part 621 is arranged in opposite offset to the recessed part 611, that is, the protruding part 621 and the recessed part 611 are not arranged in opposite, but are arranged in dislocation. The axis 20 is an axis passing through the bottom of the recessed part 611, and the convex part of the protruding part 621 is located on one side of the axis 20. The limiting frame 3 is provided with a positioning rod 7, and the guide rod 71 of the positioning rod 7 is inserted into the guide groove 6. When the button 1 is pressed, the sliding block 2 moves relative to the guide rod 71, and the guide rod 71 moves in the guide groove 6. When the guide rod 71 moves to the recessed part 611, the protruding part 621 locks the guide rod 71 to prevent it from bouncing back. In the above technical solution, when the button 1 is not pressed, the sliding block 2 cuts off the catheter 5. When the catheter 5 needs to be connected to the fluid, the button 1 is pressed, the sliding block 2 moves, the catheter 5 is released and connected, the guide rod 71 moves along the guide groove 6 to the recessed part 611 and is positioned, and at this time the button 1 is released, and the elastic force of the elastic member cannot reset the guide rod 71, so that the catheter 5 realizes the normally open state. If the button 1 is pressed and the guide rod 71 has not moved to the recessed part 611, the button 1 is released, the sliding block 2 is reset by the elastic force of the elastic member, the guide rod 71 is reset synchronously, and the catheter 5 is cut off. This operation mode can realize the instantaneous opening and closing of the catheter 5, which is used for intermittent connection of the fluid. Through the above technical solution, the user can control the catheter to be normally open or intermittently open and close through the button, which is convenient for controlling the opening and closing of the catheter according to the needs.

[0026] The guide groove 6 is annular in the embodiment, and the guide groove 6 has a lower notch 63, and the lower notch 63 and the recess 611 have a first guide section 64 and a second guide section 65, respectively, and the first and second guide sections are located on both sides of the lower notch 63. The initial position of the guide rod 71 is arranged in the lower notch 63, that is, the position when the button 1 is not pressed. When the button 1 is pressed, the guide rod 71 moves along the first guide section 64 to the recess 611, and when it is released halfway, the guide rod 71 returns to the initial position along the first guide section 64, and when the guide rod 71 moves to the recess 611, the guide rod is locked. When the button is pressed again, the guide rod is released from the recess 611 and enters the second guide section 65, and at this time, the button 1 is released, the slider 2 is reset, and the guide rod 71 returns to the initial position along the second guide section 65. The first guide section 64 includes a first guide groove 641 connected to the lower notch 63 and a second guide groove 642 connected to the recess 611, and a first bending part 643 is arranged between the first and second guide grooves. The second guide section 65 includes a third guide groove 651 connected to the recess 611 and a fourth guide groove 652 connected to the lower notch 63, and a second bending part 653 is arranged between the third and fourth guide grooves. Through the above technical solution, the first to fourth guide grooves are inclined grooves, the guide rod 71 changes direction at the first and second bending parts 643, and the moving path can be shortened to enable the guide rod to move quickly in the guide groove. The recess 611 and the protrusion 621 are provided with a guide-in section 66 and a guide-out section 67 connected to each other, the guide-in section 66 is connected to the second guide groove 642, the guide-out section 67 is connected to the third guide groove 651, so that the guide rod 71 can enter the recess through the guide-in section 66 and leave the recess through the guide-out section 67, and the guide-in section and the guide-out section are inclinedly arranged on both sides of the recess.

[0027] In the embodiment, the slider 2 is connected to the button 1 through the connecting rod 8, the connecting rod 8 passes through the limiting frame 3, so that the button 1 drives the slider to move through the connecting rod 8, and two parallel connecting rods 8 are arranged in the embodiment. The elastic member 4 is at least two, and the elastic members 4 are arranged in parallel to make the movement of the slider more stable. The positioning rod 7 is provided with a fixed column 72 connected to the limiting frame at one end and a guide rod 71 at the other end, so that the two ends of the positioning rod 7 can be arranged on the limiting frame and distributed on the slider and the limiting frame. The limiting frame 3 includes a first side plate 33 and a second side plate 34, and the two first side plates 33 and the second side plate 34 are connected to form a hollow part 35, and the slider 2 is arranged in the hollow part 35, so that the slider 2 can move in the hollow part 35, and the limiting frame in the embodiment is rectangular. The slider 2 and the inner wall of the hollow part 35 are provided with mounting columns 36, and the elastic member 4 is sleeved on the mounting columns 36, which is convenient for the installation of the elastic member 4.
