when the broken stones are sucked through the suction pipe 61, the anti-blocking unit 7 prevents stones with relatively large sizes from blocking the pipe orifice to influence the suction of the stones; compared with the prior art, the calculus can be flushed away without reversely spraying liquid through the 61-way suction pipe, so that the damage to the human body can be avoided, and the operation effect is improved.
In this embodiment, the anti-blocking unit 7 includes an elastic block 71; the elastic block 71 is fixedly connected with the end face of the suction pipe 61 far away from the suction device 6, and the elastic block 71 is symmetrical and is arranged close to the inner wall of the catheter 2;
in this embodiment, the end surface of the suction pipe 61 far away from the suction device 6 is fixedly connected with a buffer block 9; the buffer block 9 is made of a flexible material, and the buffer block 9 can buffer the elastic block 71 after the elastic block 71 bounces the calculus;
when the calculus removing device works, the suction tube 61 sucks broken calculus; the suction tube 61 sucks the calculus outside the tube opening, and when the calculus with relatively large size moves to the tube opening of the suction tube 61, the calculus with relatively large size contacts the elastic block 71 under the suction effect of the suction tube 61 and the elastic block 71 deforms; therefore, after the staff observes that the orifice of the suction pipe 61 is blocked by the stones with relatively large sizes through the searchlighting device 4, the staff controls the suction device 6 to stop generating negative pressure through the controller, so that the stones with relatively large sizes move outwards under the action of the self elasticity of the elastic block 71, and the stones cannot block the suction pipe 61; the staff again breaks the stones with relatively large sizes; the buffer block 9 supports the elastic block 71 when the stone bends the elastic block 71;
the elastic block 71 is used for blocking the large and small stones, and the elastic block is matched with the suction device 6 to stop generating suction force, so that the large and small stones move outwards under the action of the elastic force of the elastic block 71, the stones cannot block the orifice of the suction tube 61, meanwhile, the buffer block 9 supports the elastic block 71 when the stones bend the elastic block 71, the phenomenon that the bending degree of the buffer block 9 is too large, the pushing force on the stones is too large when the elastic block 71 recovers to the original state, the stones are flicked at too high speed and impact internal organs or tissues of a human body, and the using effect of the invention is improved again.
