Problems solved by technology

[0002] At present, in modern urological patients, calculus has become a major cause of disease for patients. Laser lithotripsy and bladder stone crushing with forceps will cause certain damage to the patient's kidneys. At present, suprapubic bladder incision is mainly used to remove stones in clinical practice. Lithotripsy, ESWL bladder lithotripsy, cystoscopic vigorous lithotripsy, cystoscopic hydroelectric effect lithotripsy, ballistic pneumatic lithotripsy, extracorporeal shock wave lithotripsy, and surgical stone removal have certain limitations in the treatment of male stones. cause unavoidable damage;
[0003] In the prior art, stones are broken by means of ultrasoni

Embodiment approach

[0056] As an embodiment of the present invention, the liquid in the hydraulic channel 81 is physiological saline;

[0057] When working, the suction device 6 generates negative pressure and sucks the sliding block 74 through the liquid in the hydraulic passage 81, so that the sliding block 74 moves toward the direction close to the suction device 6; the controller controls the suction device 6 to increase the pressure in the hydraulic passage 81. Liquid pressure, so that the sliding block 74 slides towards the direction away from the suction device 6, and then the sliding block 74 moves back and forth in the sliding groove 73, and the cutting block 72 on the sliding block 74 cuts and breaks the stones to prevent the stones from blocking the suction pipe 61; The liquid in the hydraulic channel 81 is set as physiological saline, so that the leaked liquid will not cause harm to the patient when leakage occurs between the sliding block 74 and the sliding groove 73, which ensures th...

Embodiment 1

[0064] A kind of urology calculus crushing suction equipment, comprising:

[0065] body 1;

[0066] Transfusion catheter 2, which extends into the human body and is used to widen and support the operation channel;

[0067] Sounding device 3, the sounding device 3 is located in the body 1 and is used to emit ultrasonic waves;

[0068] A search device 4, one end of the search device 4 is connected to the body 1, and the other end is located in the transmission catheter 2, and is used to scan the operation screen;

[0069] A crushing device 5, one end of the crushing device 5 is connected to the sounding device 3, and the other end is located in the delivery tube 2, for crushing stones;

[0070] The suction device 6, the suction device 6 includes a suction tube 61; one end of the suction tube 61 is connected to the body 1, and the other end is located in the delivery tube 2 for sucking crushed stones;

[0071] The front end of the suction pipe 61 is provided with an anti-block...

Embodiment 2

[0081] Compared with embodiment 1, the difference is:

[0082]In this embodiment, the anti-blocking unit 7 includes a cutting block 72; the shape of the cutting block 72 is zigzag; the end of the suction pipe 61 away from the suction device 6 is provided with a sliding groove 73; the sliding groove 73 is slidably connected with a sliding block 74; Cutting grooves 75 are evenly arranged on the inner wall of the pipe 61 away from the end of the suction device 6; the cutting grooves 75 communicate with the sliding grooves 73, and the cutting grooves 75 are slidably connected with the cutting block 72; the cutting block 72 is fixedly connected with the sliding block 74; the sliding block 74 is driven by the driving unit 8; the driving mode of the driving unit 8 includes hydraulic transmission and / or magnetic transmission;

[0083] In this embodiment, the number of sliding grooves 73 in the suction pipe 61 is at least two; the sawtooth orientations of the cutting blocks 72 fixed on...

Abstract

The invention relates to the technical field of calculus crushing treatment of urology surgery and particularly relates to calculus crushing and sucking equipment for the urology surgery. The calculus crushing and sucking equipment comprises a machine body; a catheter; a sound generating device; a searchlighting device; a crushing device, wherein one end of the crushing device is connected with the sound generating device, and the other end of the crushing device is located in the catheter for crushing calculi; a sucking device, wherein the sucking device comprises a suction pipe; one end of the suction pipe is connected with the machine body, and the other end of the suction pipe is located in the catheter and used for sucking crushed calculi; an anti-blocking unit is arranged at the front end of the suction pipe; the anti-blocking unit can be used for preventing the suction device from being blocked; and a controller which is used for controlling all the devices to operate automatically. When the suction pipe is used for sucking the broken calculi, the anti-blocking unit is used for preventing the calculi with relatively large sizes from blocking a pipe orifice and affecting the suction of the calculi; and compared with the prior art, the calculi do not need to be flushed open by reversely spraying liquid through the suction pipe, so that a human body is not injured, and the operation effect is improved.
