The invention provides a
thrombus removing
system, which comprises a double-cavity suction pump, a fluid storage device, an operation tube and a waste liquid
recovery device, the double-cavity suction pump comprises a
piston rod, a first cavity and a second cavity, one end of the
piston rod is connected with a driving device, the other end of the
piston rod sequentially penetrates through the first cavity and the second cavity, and a first sealing cavity and a second sealing cavity are formed between the
piston rod and the first cavity and between the
piston rod and the second cavity respectively; when the
piston rod moves from one side of the second cavity to one side of the first cavity, the first sealing cavity and the second sealing cavity are enlarged; when the piston rod moves from one side of the first cavity to one side of the second cavity, the first sealing cavity and the second sealing cavity become smaller; the second cavity is communicated with a fluid storage device through a first guide
pipe and communicated with an operation
pipe through a second guide
pipe, and a valve is arranged at the communication position of the first guide pipe and the second cavity; the first cavity is communicated with the operation pipe and a waste liquid
recovery device through a third guide pipe and a fourth guide pipe, and the third guide pipe and the fourth guide pipe are provided with a first one-way valve and a second one-way valve respectively.
