Abstract

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.

Description

technical field [0001] The invention relates to the technical field of medical device design, in particular to a thrombus removal system. Background technique [0002] At present, the treatment methods for peripheral venous thrombosis mainly include minimally invasive interventional therapy (including catheter thrombolysis, balloon dilatation, stent implantation, etc., the main disadvantages are long catheterization time, high bleeding risk, and the need for multiple operations, etc.), surgery (Including thrombectomy, thrombectomy operation tube, etc., the main disadvantages are large trauma, large bleeding, intimal damage, etc.) and conservative drug treatment (low molecular weight heparin, warfarin and other drugs, this method has bleeding risk, Need to monitor blood coagulation, usually only for recurrence prevention) three ways, each way has corresponding disadvantages. [0003] At present, the common thrombus suction operation tube in clinical practice is to form a neg...
